Development of automatic control system for small spray dryer
In the whole process of pellet drying, in order to ensure the quality of the food after drying and improve labor productivity, it is necessary to control the drying equipment and drying process. Manual control is basic, but due to the complexity of the controlled equipment and drying process, it is often difficult to achieve better post-baking particle quality and more economical results. With the development of the electronics industry, the continuous improvement of electronic instruments and equipment has opened up a broad road for automatic control of particle drying.
The automatic control of the small spray dryer can reduce the labor intensity of the operators, reduce the number of operators, reduce the operating costs, and improve the quality of the grains after dicing. The advantages of this series make the dryer improve vitality. With the increase of equipment for small spray dryers, the cost of small spray dryers is bound to increase, which is a problem to be solved in the future.
The small spray dryer (small spray dryer / small spray dryer) of Shanghai Bilang Instrument Manufacturing Co., Ltd. is mainly suitable for the production of trace particles in universities, research institutes, and laboratories of food, pharmaceutical and chemical enterprises. It is suitable for all solutions such as emulsions and suspensions. The liquid has a broad spectrum of applicability, suitable for drying heat-sensitive substances such as biological products, biological pesticides, enzyme preparations, etc., because the sprayed material is only subjected to high temperature when sprayed into mist-shaped particles, so it is only heated momentarily It can keep these active materials from being damaged after drying.
