Brief description of supporting equipment for chicken essence production equipment
Into the 21st century, people's living standards have improved significantly. The concept of "people-oriented" has been widely accepted around the world. Chicken essence, the second-generation compound condiment in the world, has gradually replaced MSG because it is not only delicious, but also without any side effects, and has become the mainstream of seasoning products.
By the end of 2005, the annual consumption of chicken essence in China has reached 150,000 tons, and the relative replacement rate of MSG is only 20%. Therefore, the market prospects are broad, and there are a large number of talented people, experts and scholars who are interested in the development and research of the condiment industry. The following supporting conditions of chicken essence production line are for reference, I hope to help everyone. The production process of chicken essence indicates the preparation of raw materials (chicken, sugar, salt, etc.) → crushing → mixing → granulation → drying → sieve powder → packaging.

I. Smash

There are two crushing goals: one is the crushing of raw and auxiliary materials, and the powder has reached a certain fineness to meet the requirements of chicken essence production. The second is to perform secondary crushing on the agglomerated product.
Salt, sugar and monosodium glutamate are the main components of chicken essence raw materials. According to the recipe process, the ratio varies from house to house. Generally, the above-mentioned raw materials provided on the market have thick crystals and are larger than 40 mesh. They cannot be directly produced. They must be crushed into a fine powder of ≤80 mesh by a pulverizer before the fine powders can be evenly mixed together.
The pulverizer usually uses (D) type B universal pulverizer, (D) represents the diameter of the pulverizer cutter, such as 20B, 30B, 40B, 60B, etc. This type of pulverizer uses a high-speed rotating knife to pulverize the raw materials, and collects the product material through a set standard screen. The crusher is not capable of crushing any material. The working condition will be affected by the moisture content, heat sensitivity, internal structure and other factors of the material. Therefore, it is best to perform a process test when selecting the material to be crushed. Like cotton sugar, the pulverizer can easily block the screen and interrupt the pulverization. Granulated sugar and crystalline MSG are easier to crush. Generally speaking, materials with a moisture content of less than 5%, crystalline and non-heat sensitive materials have good crushing effect and high efficiency. And if the material contains a large amount of cellulose (such as Chinese herbal medicine), then the pulverizer should change some structures and make certain technical treatments to meet the production requirements.
Type B crusher can directly get the material between 5-120 mesh by changing the screen, so it is more convenient to use. However, since the materials above 80 mesh are already very thin and easy to dust, you can choose (D) type BX (that is, dust removal type). And for some manufacturers with large production volume and long working hours, we can also provide (D) BS (water-cooled). To ensure that the equipment can work for a long time, and will not damage the quality of the crushed material because of the heating inside the crushing cavity.
Pay attention to three points in the production process: First, the material must be stainless steel to meet the sanitary requirements; Second, the condition of the screen must be observed frequently to prevent the screen from being damaged and increase the number of defective materials; Three: Finish each work After that, the sieves should be cleaned in time; four: Never have hard massive debris fall into the material and enter the crushing cavity.

Second, mixed articles  

When the raw and auxiliary ingredients of chicken essence are prepared in a powdered state, the production process of chicken essence enters the second process stage-mixing.
The purpose of mixing is to evenly distribute a variety of raw materials to ensure that the quality of each batch of products remains consistent. The mixing of chicken essence production process can be divided into mixing before granulation (mixing the raw materials evenly to prepare for granulation) and mixing after the finished product (the finished granules are attached with some flavor or oily substance in the mixing).
According to the mixing method, it can be divided into dry mixing and wet mixing. Because chicken essence is wet granulated, it is inseparable from wet mixing. Wet mixing equipment must be equipped with a forced mixing device to facilitate uniform mixing of materials. There are usually two types of such equipment: twin screw cone mixers and CH groove mixers. Although the twin-screw conical mixer has strong stirring force, it is rarely used because of its dead angle and inconvenient cleaning. The CH trough mixer has many advantages: large opening, no dead angle, easy cleaning, and simple operation. These advantages have made the CH trough mixer an essential product in chicken essence production equipment.
The trough mixer is named for its horse-slot shape. The most common are two types: through-shaft ribbon type and double coulter type. The working principle is mostly the same: put the material to be mixed in the mixing chamber, usually with a loading factor of 0.4, dry mix for a few minutes, and then put raw materials such as egg liquid, water, oily substances, etc. Invert and stir to mix the materials thoroughly. The quality control point of the trough mixer is the tightness between the shaft and the mixing chamber. If the seal is not good, the fine powder will enter the gap and the bearing, and the mixer will not work properly in two or three weeks. At the same time, equipment cleaning is important after every shift.
The dry mixing is also mentioned earlier. Dry mixing is a method of mixing materials by gravity. Dry mixing before wet mixing has certain advantages: certain raw materials with very different ratios can be mixed uniformly (tens of kilograms to tens of grams) to ensure the best quality. Dry mixing equipment usually includes: V-type mixer, SYH three-dimensional motion mixer, high-speed mixing granulator.
Regardless of the type of mixer, you should pay attention to the following issues when selecting:
1. The material must be stainless steel, and all the inside and outside are polished.
2. The equipment should be free of dead corners, and the welding place should be polished carefully to prevent welding slag from entering the food.
3. The equipment should be operated under actual load. Listen to its sound to check the coaxiality of the equipment and the quality of the bearings. Water test to test its tightness.

Three, granulation articles  

The mixing of materials is to prepare chicken granules. After the mixing is completed, the production of chicken essence will enter the third process section-granulation.
There are two methods of granulation: dry granulation and wet granulation. Because dry granulation is made by external force, the granules produced are not easy to dissolve and are generally not used. Wet granulation equipment includes: boiling granulator, swing granulator, rotary granulator, twin screw extruder. The granules produced by the above four devices are more distinctive, and are introduced one by one.
The working principle of the boiling granulator is: put the dry powder of the material directly into the equipment and fluidize it by the air inlet system. During the powder fluidization process, the binder is continuously sprayed, and the powder is agglomerated into particles by the binder. , And the continuous hot air makes the particles dry quickly. The characteristics of this equipment are loose granules, fast dissolving speed, mixed granulation in one step, and stable product quality. Disadvantages are high equipment cost and low output, which are generally used for the production of high-end condiments.
Swing granulator is now the most common granulation equipment, which can adapt to various formulas, including high sugar, high salt, high starch, high humidity. By changing different screens, it can be made into granules of different sizes, and the produced granules dissolve fast. The equipment has small investment, easy maintenance and simple operation. In the process of use, pay attention to the use of nylon screens as much as possible to avoid the danger of metal mixed with food due to broken wires in stainless steel screens.
The advantages of the rotary granulator are: the granules are cylindrical (φ1.2-1.8mm) and the appearance is beautiful. However, the formula of chicken essence is highly critical. In general, formulas with high sugar content are not suitable for rotary granulators, because long-term friction can easily dissolve sugar, which affects the granulation continuity. Formulas with high starch and high maltodextrin are also not suitable for spinning. Granulators, this type of formula consumes considerable screen mesh. However, with the development of technology and the improvement of technology, these problems have been solved to varying degrees. At the same time, the granules made by the rotary granulator are tight and have poor solubility.
The characteristics of the twin screw extruder are: it can be made into extremely small cylindrical particles (φ0.5-1mm), the particles are particularly beautiful and neat, but they are rarely used due to their high compactness and poor solubility.
The selection of granulation equipment should be comprehensively considered and comprehensively selected according to many factors such as the shape, solubility, and composition of the granules. Only in this way can the beautiful and good quality chicken essence be produced.

Fourth, dry articles  

After the chicken essence granules are made, the next step is to choose suitable drying equipment to dry them for subsequent screening and packaging services.
Drying is a very critical step in the entire chicken essence production line. The drying temperature and drying rate have a direct impact on the quality (color, aroma, taste) of chicken essence.
According to the method of drying materials, we can divide the drying equipment into intermittent equipment (such as oven, ebullating bed, high-efficiency boiling dryer, etc.) and continuous equipment (such as vibrating fluidized bed, belt dryer). The characteristics of the sexual equipment are described in detail.
The oven is commonly called "universal dryer", which is named for its strong adaptability and simple operation. Specifically, a plurality of drying cars are placed inside the box dryer, and a plurality of drying plates are placed on the drying machine. Materials to be dried are placed in the drying plate, and the door is closed for heating.
Now the hot air circulation oven has complied with the national industry standards after food and medicine management. Compared with the soil drying room and thermal efficiency that appeared before, it has become an entry-level equipment in the production of chicken essence. Because it is small and easy to operate.
While the oven embodies its advantages in use, it also has many deficiencies, such as low efficiency, high labor intensity, easy to agglomerate materials (reduced yield), long drying time, easy to destroy color, fragrance and taste.
In response to the above situation, the manufacturer has made many improvements and increased its thermal efficiency by installing a thermal insulation layer. The inlet air adopts adjustable air distribution plate to uniform the temperature difference between the top and bottom of the oven. At the same time, the microcomputer and sensitive thermometer are used to control the temperature of the oven to ensure that the temperature in the oven is uniform and stable. The stable temperature control system is the guarantee of the quality of chicken.
When using the oven to dry chicken essence, pay attention to the following points: The baking tray must use a stainless steel mesh plate or a stainless steel punching plate (the mesh number and punching diameter of the baking tray depends on the size of the chicken essence particles), and the material must be evenly distributed. So that the drying effect is more even. The opening of the air-conditioning blade is as large as possible, so that there is enough air volume to carry away water. An air filter should be installed at the air inlet and outlet to ensure compliance with sanitary requirements.
Owing to certain shortcomings of the oven, horizontal boiling dryers were welcomed by many manufacturers as soon as they appeared.
The principle of the boiling dryer is: let the hot air quickly pass through the bed with many small holes, design the wind speed and wind pressure, and blow the chicken essence particles staying on the bed to form a boiling shape. Because the whole particles are suspended in midair, the chicken essence particles are completely wrapped by the hot air, the dry surface area is greatly increased, and the air that completes the heat exchange is discharged out of the drying chamber by the induced fan. Because the hot air is passed through in a single pass, the drying rate is greatly accelerated. At the same time, for the same reason, the thermal energy of the entire drying system is a one-time use, and the energy consumption is large.
The operation method of the boiling dryer is also one-time feeding, discharging after the drying, and belongs to the intermittent drying equipment with the oven, which has obvious advantages, higher drying rate and less labor intensity (compared with the oven). Because there are many control points, the quality of dried chicken essence is better and the yield per unit time is high. At the same time, because the entire equipment is composed of the host, heater, cyclone separator, dust collector, fan and other equipment, and has a large number of controllable factors, the equipment manufacturers and equipment operators have higher requirements.
Because boiling dryers are still intermittent production equipment, for manufacturers who need high output. Continuous production equipment is inevitable. The linear vibration fluidized dryer is currently used in the chicken essence industry to use more continuous drying equipment . It can complete the drying of chicken essence in 2-5 minutes. Due to the shortening of the drying time, it can make the chicken essence particles completely. It is possible to maintain the color and fragrance shape in the design, and the capacity is designed according to the customer's needs. Generally speaking, the width of the equipment determines the yield, and the length of the equipment determines the drying time and final moisture content of the chicken fine particles. One end of the linear vibration fluidized dryer feeds the other end, and the chicken fine particles are on the perforated bed. The running power is from the forward excitation force generated by the vibration motor of the equipment. At the same time, the designed wind direction also makes the particles continue to move forward. In addition, the excitation force generated by the vibration motor simultaneously throws the chicken fine particles off the bed board and penetrates at high speed. The combined hot air forces the particles into a fluidized state and completes the drying on a similar drying principle to an ebullated bed.
Because the chicken essence particles have their own characteristics: moisture ≤10% (holding the material into a ball, falling and spreading), and at the same time there is a certain amount of oily substances (mainly onion oil, ginger oil, sesame oil and other components), oil-water combined materials have Certainly sticky. And how to ensure that the material flows smoothly on the drying bed? How to ensure that the equipment has no dead ends? (Materials accumulating in dead corners for a long time will cause coking of the materials, which will affect the quality of chicken essence.) How to ensure that the exciting force of the equipment can fluidize the fine particles of chicken, and it will not break the particles due to the excessive excitation force. Crushed particles mean that the product powder is increased and the qualified rate is decreased.
To answer the above series of questions, it is necessary to communicate with the customer before the equipment design and actively understand the parameters. In the design, the equipment should be given a certain capacity and adjustability margin based on production design experience. Generally speaking, the selection of the opening rate, opening direction, hole size, and fan model of the bed board should be determined in the design of the equipment, and some parameters should be given a certain adjustable range. The specific operating parameters should be obtained after the equipment is installed, carefully debugged, and continuously revised.
The chicken granules are fed from the feed inlet of the vibrating fluidized bed to the feed outlet after drying, and the time is about 2--5 minutes. Although the time is short, the entire drying process is quite complicated.
In view of the characteristics of chicken essence particles, our company has adopted the following steps in the production equipment: rough bed surface and fast forward drying air are used at the beginning of the fluidized bed to avoid the accumulation of chicken essence at the feeding opening. Piece). In the second stage, the medium-high temperature drying with large air volume is adopted, so that the chicken essence can be dried in a short time.
At the end of the vibrating fluidized bed, there are usually two forms: one is the drying section connected to the sieve section (this section is not covered), allowing the chicken essence particles to directly contact the natural air to complete the cooling. The advantage is that screening and cooling are completed in one step. The disadvantage is the higher environmental requirements for the entire workshop (sanitary conditions and workshop temperature). The other is to connect the drying section with the cooling section (this section has an upper cover), so that the natural wind or cooling air with large air volume can complete the cooling. The advantage is that the cooling is more thorough. The disadvantage is that one-time screening cannot be completed and a separate screening machine is required.
Because the air volume of the vibrating fluidized bed is relatively large, some powder is usually discharged with the induced draft fan. Therefore, the fluidized bed should be equipped with a cyclone separator to collect some fine materials.
The vibrating fluidized bed is prone to metal fatigue due to long-term working in the excitation force (such as defective design or production, the bed welds are easily cracked, causing loose beds), and the longer or wider bed, and It is easy to deflect the materials (the materials are gathered in the middle of the screen or dispersed on both sides of the screen to run towards the discharge port, which causes a partial bed.) Therefore, when selecting equipment, be sure to choose equipment that meets the design requirements, not for price. Cheap, choose equipment that doesn't guarantee business quality.
The following introduces the mesh belt dryer (highly recommended)
This unit has the advantages of large output (500-2000 kg per hour is more suitable), uniform particles, not easy to break, and small product powder. It is a commonly used continuous static drying equipment . It is generally composed of a material conveying mechanism, One or several separate drying chambers. The material is evenly spread on the mesh belt and driven by the conveying mechanism to move in the drying chamber. The hot air penetrates the material layer to make the water evaporate to achieve the purpose of drying. Each drying chamber is heated by the cabinet System, hot air circulation fan, exhaust system, etc. Under the same output, compared with fluidized bed, it has the advantages of low power, low energy consumption and noise, good unit stability, low failure rate, and less fine powder.
According to our many years of experience and the requirements of the pharmaceutical and food industries for our equipment, our company has made great improvements to the original traditional belt dryer.It mainly has the following characteristics:
1. The hot air passes through the material from bottom to top and from top to bottom, which increases the contact area between the material and the hot air and improves the drying speed.
2. The entire equipment adopts a fully enclosed structure. In addition to the exhaust air duct, there is no outer duct, thereby ensuring that the materials are not polluted, improving thermal efficiency, and improving working conditions.
3. With unique internal air supply duct, hot air with low humidity in the rear unit can be delivered to the front unit as a preheating of high humidity materials in the front, which not only improves the thermal efficiency, saves energy, but also increases the drying speed.
4. The drying room heating system and circulation fan are placed separately on the side, and at the same time, there are access doors on both sides, which can easily access all the parts of the dryer, which is convenient for cleaning the inside of the host.
5. The temperature of each unit can be independently and automatically controlled by a solenoid valve, so that the materials can be used at different temperatures under different humidity conditions.
6. All key parts and components are made by domestic and foreign well-known manufacturers to ensure the long-term normal operation of the equipment.
7. The speed of the mesh belt is controlled by frequency conversion, and the line speed of the mesh belt can be displayed on the electrical control box intuitively.
8. All air inlets are equipped with medium efficiency filters to ensure clean air inlet.
9. The temperature of each unit of the unit is controlled independently and automatically, and has digital display, which greatly improves the operability of the equipment.
10. The unit is equipped with a cooling section, which is convenient for screening and packaging after the material is cooled.
11. It is used in conjunction with a special swing granulator (YK-1200F, with granulation and cloth function) and a linear square vibrating screen (FS1-2, three outlets) to reduce labor intensity and improve the cloth and screening effect.

V. Screening and auxiliary equipment  

Crushing, mixing, granulating, and drying are the four major steps in the production of chicken essence. The equipment involved is the main equipment, but at the same time it cannot be separated from many auxiliary equipment, such as: screening, packaging, heating systems, conveying systems, etc. Let me explain.
After the chicken essence particles are dried, the dried particles need to be sieved to separate particles of uniform size as a commodity package. Normally, the screening machine chooses a three-outlet vibrating sieve, which has both cooling and screening functions. The size of the upper and lower screens is determined according to the size of the granulation, which usually covers the number of granulation meshes. For example, granulation is performed with a 16-mesh screen, and the vibrating screen is selected from 10 to 20 mesh. If the screen adjustment interval is large, the yield is increased, otherwise it is decreased.
In the production of chicken essence, most of them will produce agglomeration. If it is reworked, it will be too wasteful. Now there is a granulator to solve this problem. The granules can be obtained immediately when the agglomerate enters the granulator. But also there is partially powder end produce.
Packaging can be divided into mechanical packaging and manual packaging, usually small-scale production requires only manual packaging. You can also manually pack, wait for market feedback, and then launch a packaging machine that sells well.
The heating system can be divided into steam heating, electric heating, heat transfer oil heating, fuel oil / coal hot air stove heating. A common heating method is steam. The advantage is clean energy, easy to control, and the temperature produced is similar to the temperature required for production. Electric heating is usually used on small equipment. The advantages are easy to use and strong adaptability. But compared to other energy sources, the running cost is higher. Heat transfer oil heating is generally not used due to the high temperature. Oil-fired / coal-fired hot air stoves are also often used. In the selection, the inner stainless steel should be selected. At the same time, the indirect heat exchange type should be selected, and the direct combustion type should not be used.
The conveying equipment needs to be comprehensively designed according to the conditions of the production site. The usual selection method is ① linear feeding method: the conveyor belt is at the same height as the feeding port, and the granules are directly sent to the dryer through the conveyor. But the premise is that either the granulator is on the platform, or the dryer needs to be sunk and placed. ②Slant wire feeding method: The granulator makes the granules forward through a linear conveyor, and falls to the slope conveyor at the end, and the slope conveyor feeds upwards. Depending on the formulation of the material, a belt or a smooth belt can be selected.
The above-mentioned equipment is made from the pulverization process. If chicken essence is made from fresh chicken, the process will be more complicated and the equipment will be more. The following equipment is usually involved: meat grinder, colloid mill, digestion tank, filter, homogenizer, spray dryer, etc. It is also important to note whether the manufacturer has a certain scale of technology, rich production experience and debugging experience. This will make yourself less detours. If you buy the equipment by yourself, there will be certain risks.
When equipping the production line to purchase equipment, we must pay attention to the following aspects to avoid affecting the normal operation of the enterprise due to mistakes in selecting equipment.
1. The actual scale of the equipment manufacturer, whether the operating conditions are stable production sites or temporary leases and so on.
2. The comprehensive technical strength of the equipment manufacturer and the design ability of a single product, customer reputation, market share, company financial resources and other factors.
3. Actual production supporting experience and debugging experience of the production line.
Various factors must be considered before making a firm decision, avoiding detours, cheap maps, hasty choices, and even patchwork,
Otherwise there is a lot of risk.
All in all, only the perfect combination of recipe-process-equipment can produce high-quality chicken essence.
