Seven advantages of microwave vacuum drying equipment

foreign developed countries began to develop industrialized microwave vacuum drying equipment in the 1980s, and achieved good results in practical application. France international microwave company uses microwave vacuum drying equipment to process seedless raisins. The traditional process of 65 ℃, 24-hour hot air drying is changed to 50 ℃, 5-hour microwave vacuum drying. The product quality and output are greatly improved. Pengzhou microwave equipment Co., Ltd. took the lead in developing microwave vacuum equipment in China. Through several years of efforts, it has completed the development of industrialized 10kW microwave vacuum drying equipment. It provides a new and efficient drying equipment for calculating the polar moment of inertia of samples for pharmaceutical engineering, biological engineering, chemical engineering, material engineering and deep processing of agricultural and sideline products

the following are the major advantages of microwave vacuum low-temperature drying:

1. Efficient conventional vacuum drying equipment uses steam for heating, which needs to be heated from the inside to the outside. The heating speed is slow and requires a lot of coal. While microwave vacuum drying equipment uses electromagnetic wave heating, which does not need heat transfer medium, and it can't see the inside of good or bad bodies directly when heated to the outside world, and the heating speed is fast, The 1 kW microwave can heat the water under normal temperature to 80 ℃ in minutes, avoiding the above shortcomings, so it has fast speed, high efficiency, greatly shortened drying cycle and reduced energy consumption. Compared with the conventional drying technology, which is an effective technology to avoid the loss of building energy consumption by adopting building thermal insulation materials, the work efficiency can be increased by more than four times

2. Heating is uniform. Due to microwave heating, the material is heated from inside to outside at the same time. The internal and external temperature difference of the material is very small, which will not produce the inconsistent internal and external heating in the conventional heating, resulting in the expansion effect, which is conducive to crushing and greatly improve the drying quality

3. Easy to control, convenient for continuous production and automation. Because the microwave power can be adjusted quickly and has no inertia, it is easy to control immediately, and the temperature can be adjusted arbitrarily between 40 ℃ -80 ℃

4. The equipment is small in size, convenient in installation and maintenance, and does not occupy too much space

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

6. Microwave has the efficacy of disinfection and sterilization, and the product is safe and hygienic. Long shelf life

7. Significant economic benefits. Traditional drying requires a long time, slow speed, high energy consumption and high processing cost. Microwave heating can save a lot of energy and improve the speed of heating and drying. This is because microwave has penetrability. When heating objects, it does not need any media, and it can heat the inside and outside of materials at the same time. According to the data at home and abroad, the speed and efficiency of heating materials with microwave equipment are 4~10 times that of conventional heating methods

from the features introduced above, we can see the remarkable economic and social benefits from the aspects of energy saving, consumption reduction, improving product quality, safety and health, and low equipment investment cost. The new industrialized microwave vacuum drying equipment developed by our company has formed a series of products from 2kw-50kw microwave vacuum drying equipment. This will provide a modern high-tech drying equipment for many fields of our national economy and scientific research departments. (end)
