Spray drying equipment is a type of drying equipment used in most chemical and food industries to make solutions and suspensions into powder. It uses materials and hot gas to make full contact through co-current, etc., so as to dry quickly, and is a powerful tool to obtain powdery finished products. Spray drying equipment has a good drying effect, and the dust pollution is small, so it is very popular in the industry. However, there are also some problems with the spray drying equipment that will affect the drying effect of the entire material. So I will briefly analyze the problems and solutions that often occur during the use of the spray drying equipment .
1. The spray drying equipment has uneven atomization. This situation is usually a blocked nozzle or abrasion in some places. The nozzles of the replacement equipment should be cleaned frequently.
2. Intake and exhaust temperatures are inappropriate, too high or too low. This situation is all about stress. During use, the air intake and exhaust pressure of the machine must be adjusted correctly.
3. After drying, the finished product has high moisture content and poor drying effect. There are many possibilities to cause this situation. Materials, drying temperature, air intake, heating area, etc. may all affect, so you should first find the reason and adjust it.
4. The dried product has impurities or color difference. Generally, it is not cleaned in the air. It may also be affected by the temperature being too high or too low during thermal processing. The entire material is a form, which causes color difference.
The above is a brief summary of the editor, the specific situation is to ask a professional maintenance master.
