Microwave vacuum drying equipment is a new type of microwave energy application equipment combining microwave energy technology and vacuum technology. It has a series of advantages of microwave and vacuum drying, and overcomes the shortcomings of conventional vacuum drying cycle and low efficiency. In the drying process, the work efficiency can be improved by 4 to 10 times compared with the conventional method.
The purpose of drying is for the purpose of material use or further processing. In addition, the dried material is also convenient for transportation and storage, such as drying the harvested food to a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, various mechanized dryers are becoming more and more widely used.
1. Efficient and conventional vacuum drying equipment is heated by steam. It needs to be heated from the inside to the outside. The heating speed is slow and it takes a lot of coal. The microwave vacuum drying equipment uses electromagnetic wave heating. It does not need heat transfer medium and is directly heated to Inside the object, the heating rate is fast, the efficiency is high, the drying cycle is greatly shortened, and the energy consumption is reduced. Compared with conventional drying technology, it can improve work efficiency by more than four times.
2, heating evenly due to microwave heating, the material is heated simultaneously from the inside to the outside, the temperature difference between the inside and outside of the material is very small, does not produce the situation of internal and external heating inconsistent in the conventional heating, resulting in the effect of puffing, which is conducive to crushing, so that The quality of drying is greatly improved.
3, easy to control, easy to continuous production and automation, due to the rapid adjustment of microwave power and inertia, easy to control, you can adjust the temperature between 40 °C -100 °C.
4, small volume, easy installation and maintenance 5, product quality is good, compared with the conventional method, the quality of processed products has been greatly improved.
6, microwave has the effect of disinfection, sterilization, product safety and hygiene. The shelf life is long.
7. The economic benefits are significant.
From the above-mentioned characteristics, energy saving, consumption reduction, product quality improvement, safety and hygiene, and low equipment investment cost can be seen to show significant economic and social benefits.
