How to make microwave vacuum dryer dry at low temperature

What is the difference between the intelligent static microwave vacuum dryer and the traditional dryer?
The heat energy of traditional heating method is conducted by conduction, convection and radiation, and it is difficult to conduct air convection in vacuum state Only by conduction, heat energy is transmitted to materials, from the surface of materials to its interior When drying paste like materials, its surface is first dried and hardened, forming a "solid" shell, and it is more difficult to discharge internal moisture Therefore, the drying speed is slow and effective Low rate, long cycle, large thermal inertia, temperature is not easy to control, which directly affects the drying quality of the goods The characteristic of static microwave vacuum drying is that the evaporation temperature of water in the drying process is directly related to atmospheric pressure The lower the atmospheric pressure is, the lower the boiling point of water is The boiling point of water at an atmospheric pressure is 100 ° C when the real air is less than - 0.08 MPa, the evaporation temperature of water is 30-40 ℃ Therefore, under the condition of vacuum, the material can be dried at low temperature The static microwave vacuum dryer does not need the rotating device, it can complete the uniform drying, which is twice the loading capacity of the rotating dryer There are no problems such as turning over, dropping, blocking, etc there is no safety problem of internal ignition of the equipment, which can reduce more than 15% of the energy consumption Therefore, it has the characteristics of high quality, low cost, large output, high efficiency, stable operation of the equipment, etc
Microwave drying is that the material absorbs the microwave energy and generates heat by itself The transmission of microwave energy will not be affected in vacuum state Therefore, the material can be heated by microwave rapidly and has high thermal efficiency At the same time, the material is not easy to form the problem of external drying and internal humidity in the drying process When drying, the gas is easy to be discharged, the drying temperature is low, the drying speed is fast and the quality is high, and the effective composition of the material is more Of them
Intelligent static microwave vacuum drying equipment is a comprehensive high-tech equipment integrating microwave energy application technology and vacuum drying technology It is mainly used for low-temperature drying of materials such as extract, pill, granule of traditional Chinese medicine, beef sauce, chicken sauce and vegetable in food The materials are dried evenly under static state, which has fast drying speed, high thermal efficiency It is characterized by low drying temperature, high drying quality, low cost and stable operation of equipment It is a high-quality, fast and low-temperature drying equipment.
