Latest company news about Pressure swing vacuum drying equipment is easy to dry heat-sensitive materials

Vacuum drying equipment is a device that removes moisture from the internal components of packaging containers by evacuating the air inside to a predetermined vacuum degree. It is specially designed for drying heat-sensitive, easily decomposing and easily oxidizing substances. Inert gas can be filled inside, and even some complex items can be dried quickly.

 

When drying under low pressure, the oxygen content is low, which can prevent the oxidation and deterioration of the dried materials and is suitable for drying flammable and explosive dangerous goods. It can vaporize the moisture in the material at low temperatures, making it easy to dry heat-sensitive materials. It can recover the valuable and useful components from the dried materials. It can prevent the emission of toxic and harmful substances in the dried materials and is an environmentally friendly type of "green" drying equipment.

 

As a green drying equipment, the market prospect of vacuum dryers is broad. Domestic enterprises have now accelerated their research on vacuum drying technology. Some enterprises have even made breakthrough progress, which to a certain extent has reduced energy consumption, alleviated pollution, and brought more benefits and value to society. At the same time, they have also gained a relatively large share of the drying machine market for themselves.

 

Although there is still a certain gap in the production of drying equipment in China compared with developed countries at present, the advantages of domestic equipment are gradually being established and the domestic market has basically been dominated. Vacuum drying equipment will become the mainstream of market demand. Domestic industries need to significantly enhance their technological levels, increase drying efficiency, reduce energy consumption, and contribute their own strength to achieving green production.

 

 

When exploring new development paths for dry skills, it is necessary to comprehensively consider energy efficiency, environmental protection and product quality in order to achieve comprehensive, harmonious and sustainable development. To implement an efficient and green drying development strategy, it is essential to first embark on a resource-conserving development path, transforming from a single and extensive drying method to a combined and intelligent one. Not only should fundamental renovations be made in the drying process, but also comprehensive and multi-level energy-saving technological renovations should be carried out, and the application of drying technologies using renewable energy and industrial waste heat should be vigorously promoted.

 

Efficient and conventional vacuum drying equipment all use steam for heating, which requires heating from the inside out. The heating speed is slow and it consumes a lot of coal. However, microwave vacuum drying equipment uses electromagnetic wave heating, does not require a heat transfer medium, and directly heats the interior of the object. It has a fast heating speed, high power, a significantly shortened drying cycle, and reduced energy consumption. Uniform heating: Due to microwave heating, the material is heated from the inside out simultaneously, resulting in a very small temperature difference between the inside and outside of the material. This avoids the inconsistent heating between the inside and outside that occurs in conventional heating, thus creating a puffing effect, which is conducive to crushing and significantly improves the drying quality.
