Low Temperature Microwave Vacuum Dryer,Pharmaceutical Vacuum Dryer

Summarize:In traditional heating methods, heat is conducted by convection, conduction, and radiation, and penetrates from the outside to the inside. However, it is difficult to conduct heat through convection in air under vacuum conditions. Only heat conduction and radiation are used to provide heat energy to the material. High surface temperature The internal temperature is low, the temperature difference between inside and outside is large, and the temperature is difficult to control. Therefore, the conventional vacuum drying method has slow thermal conduction speed, large energy consumption, low efficiency, and long drying time.Microwave heating is a type of radiant heating, in which microwaves directly act on an object, causing it to be heated both inside and outside, without having to transfer heat by convection or conduction. Therefore, the heating speed is fast, the thermal efficiency is high, the processing time is short, and the temperature inside and outside the material is uniform. Energy conservation, high drying efficiency, and good drying quality. Intelligent static microwave vacuum drying equipment is a new type of microwave energy application equipment that combines microwave energy technology and vacuum technology and is controlled by high-tech intelligence. It combines the advantages of microwave drying and vacuum drying, while overcoming conventional vacuum. The disadvantages of high drying temperature, long time, large energy consumption, drying temperature in the general material, drying temperature 30-60 degrees Celsius, with high drying yield, good quality, low processing cost, and can accurately control the moisture through intelligent control system advantage. In addition, when the oxygen content is low at low temperature and low pressure, the oxygen content of the material to be dried is reduced and the oxidation reaction of the material to be dried is weakened, which ensures the flavor, appearance and color of the material. It is easy to dry the heat-sensitive material, especially the extract of traditional Chinese medicine extract, beef sauce, and chemical raw materials. The low temperature drying of agricultural products has its unique advantages.Application:Microwave vacuum dryer is mainly used for dehydration drying of high value-added and heat-sensitive agricultural and sideline products, health products, food, medicinal materials, fruits and vegetables, chemical raw materials, etc.; used for low-temperature concentration of chemical products, removal of crystal water, enzymes drying of preparations; vacuum extraction of medicinal herbs; suitable for laboratories of scientific research institutes.Technical Parameters:
