The traditional heating method is carried out by conduction, convection and radiation. Under vacuum, air convection is difficult to carry out. Only by conduction, heat energy is transferred to the material, from the surface of the material to the inside. When the paste material is dried, the surface is first Dry hardening, forming a "solid" shell, the internal moisture discharge is more difficult, therefore, the drying speed is slow, the efficiency is low, the cycle is long, the thermal inertia is large, the temperature is not easy to control, and directly affects the dry quality of the article.
Static microwave vacuum drying features
The evaporation temperature of the material during the drying process is directly related to the atmospheric pressure. The lower the atmospheric pressure, the lower the boiling point of water. The boiling point of water is 100 ° C at one atmosphere, and the water is less than -0.08 MPa. The evaporation temperature is 30 to 40 °C. Therefore, the object can be dried under low temperature conditions under vacuum conditions.
The static microwave vacuum dryer can complete uniform drying without rotating device, which is twice as large as that of rotary dryer. There is no problem of turning over, falling off, jamming, etc. There is no safety problem inside the equipment, which can be reduced. More than 15% of energy consumption, therefore, it has the characteristics of high quality, low cost, large output, high efficiency, and stable equipment operation.
Microwave drying is the self-heating of the material after absorbing microwave energy. The transmission of microwave energy in the vacuum state will not be affected. Therefore, the material can be quickly heated by the microwave as a whole, and the thermal efficiency is high. At the same time, the material is not easy to form in the drying process. The problem is that the gas is easily discharged during drying, the drying temperature is low, the speed is fast, the quality is high, and the active ingredients of the material can be more retained.
Intelligent static microwave vacuum drying equipment is a comprehensive high-tech equipment combining microwave energy application technology and vacuum drying technology. It is mainly used for Chinese medicine extracts, pills, granules, beef sauce, chicken sauce and vegetables in food. When the material is dried at low temperature, the material is uniformly dried in a static state. It has the characteristics of fast drying speed, high thermal efficiency, low drying temperature, high drying quality, low cost, stable operation of the equipment, etc. It is a high quality, fast and low temperature drying. equipment.
