The drying process of the pressure spray dryer is that the materials are pumped into the spray dryer and dispersed into small droplets by the atomizer; After heating, the air is sent into the drying room to mix and come into contact with the material mist; After completing the drying process, the dried products are separated and stored in storage or directly put into use.

The milk powder produced by the pressure spray dryer spray drying method is a uniform powder product. It does not need drying, jelly, crushing and other processes, and it is directly packaged into finished products, which makes the production process of milk powder mechanized, continuous and large-scale, and improves the quality of milk powder products because the surface temperature of the material is not too high. Therefore, the pressure spray dryer has played a huge role in the production of milk powder industry, and there is a trend that the amount of dry water is increasing.

Firstly, it can dry the material into powder in a short period of time, which not only greatly improves the drying efficiency, but also saves some processing steps and simplifies the processing process. In addition, using this equipment for drying treatment can also be flexibly adjusted according to actual needs to meet different drying needs.

Pressure spray dryer is a kind of drying equipment used in most chemical and food industries to make solutions and suspensions into powder. It utilizes materials that come into full contact with hot gas through co flow and other means to quickly dry, making it a powerful tool for obtaining powdered finished products.

However, the pressure spray dryer will also have some problems that will affect the drying effect of the whole material, such as uneven atomization, which is generally caused by nozzle blockage or local abrasion. The nozzles of the equipment should be cleaned and replaced frequently; Improper intake and exhaust temperatures, whether too high or too low, require proper adjustment of the machine's intake and exhaust pressures during use.

The finished product dried by the pressure spray dryer has high moisture and poor drying effect, which may be caused by many factors, such as materials, drying temperature, air inlet volume, heating area, etc., so the reason should be found first and then adjusted. Dry finished products have impurities or color differences. Generally, the air is not cleaned thoroughly, and it is also possible that the temperature during hot processing is too high or too low, which affects the form of the entire material and leads to color difference.
