Use Characteristics of Vacuum Dryer

Use characteristics of vacuum dryer

1. High-efficiency conventional vacuum dryers use steam for heating, which needs to be heated from inside to outside. The slow heating speed requires a large amount of coal. The microwave vacuum drying equipment uses electromagnetic wave heating without heat transfer media. Inside the object, the heating speed is fast, the efficiency is high, the drying cycle is greatly shortened, and the energy consumption is reduced.

2. Uniform heating. Due to microwave heating, the material is heated from the inside to the outside at the same time. The temperature difference between the inside and the outside of the material is very small, and the inconsistent heating between the inside and the outside will not occur in the conventional heating, thereby producing the effect of puffing, which is good for crushing and making The drying quality is greatly improved.

3. Easy to control, convenient for continuous production and automation, because the microwave power can be adjusted quickly and without inertia, it is easy to control in real time.

4. The equipment is small in size, easy to install and maintain, and does not take up too much space.

5. The product quality is good. Microwave vacuum drying equipment can extend the shelf life of food, preserve the original flavor and nutrients of the food, retain the physiological activity of the raw materials, enhance the functionality of the food, and increase the added value of agricultural products. Compared with conventional methods, the quality of processed products has been greatly improved.

6. The microwave drying equipment has the functions of disinfection and sterilization, the products are safe and sanitary, and the shelf life is long.
