At home and abroad, filter washing and drying three-in-one manufacturers equipment development imbalance

In order to improve equipment production and ensure product quality, a variety of continuous vacuum drying equipment have been developed abroad more than ten years ago. However, due to the limitations of the technical level and people's perceptions, the development is relatively slow.

1) Belt continuous vacuum drying equipment

KK-VAQ belt continuous vacuum drying equipment manufactured by Japan Hiroshima Co., Ltd. is suitable for liquid materials, mud-like, paste-like concentration and high viscosity boring drying. The BV-100.5 vacuum belt continuous drying device produced by Okawa, Japan, uses steam and conduction heating. The temperature of each section is adjustable, and the belt tension and speed are adjustable. The Swiss company Buch-Gade has developed a range of belt-type continuous vacuum drying units with automatic cleaning.

Since 1995, he has been engaged in the design, manufacture, installation and service of belt continuous vacuum drying equipment, and the technology is relatively mature.

Domestic belt continuous vacuum drying equipment is rare. In 2004, Guangdong Agricultural Science Research Institute successfully developed a small test equipment for the drying of banana powder with good effect.

2) Grain continuous vacuum drying equipment

The amount of grain dried is large and continuous drying equipment must be used. In the past, many countries have developed a number of grain drying equipment, and vacuum dried grains are mostly used for seed drying because the vacuum drying cost is too high. In fact, this is a misunderstanding. According to the senior engineer of Zhengzhou Food Science and Design Institute He Xiang, the continuous corn vacuum drying equipment developed by them has a production capacity of 60t/d. The fixed investment is slightly higher than hot air drying, running cost and hot air. Dry and flat. If considering the quality of the dried product, the breakage rate of the drying process, the waisting rate, etc., the total cost of vacuum drying at low temperatures is not higher than that of hot air drying.

3) Continuous vacuum freeze drying equipment

Food raw materials are abundant, and the output of freeze-dried products is very large. Therefore, continuous food freeze-drying equipment appears earlier.
