The market demand for drying equipment is gradually increasing, and resources should be allocated rationally.

Drying equipment, also known as dryers and dryers, is the equipment used for drying operations. The moisture (usually referred to as moisture or other volatile liquid component) in the material is vaporized by heating to obtain a solid material that is specified to contain moisture. In the process of development, drying equipment has experienced a growth process from scratch to small.

It is known that the current common drying equipment includes belt dryer, drum scraper dryer, hollow blade dryer (blade dryer), vacuum target dryer, double cone rotary vacuum dryer, spray dryer, Vacuum oven, rotary flash dryer, etc. At present, the domestic market share of drying equipment in China has reached more than 80%. It is expected that the domestic market share of domestic drying equipment will reach over 90% in the future.

However, some viewpoints point out that from the current development status, there is still a big gap between the development of China's drying equipment industry and the world's advanced level. At the same time, the long-term backwardness of technology has made China's drying equipment sector face a situation of internal and external troubles. With the intensification of international competition, various ills have gradually emerged, such as lack of innovation.

In view of the lack of innovation in the domestic drying equipment industry, some experts suggest that relevant enterprises should vigorously promote the original innovation, integrated innovation and the ability to introduce, absorb and re-innovate drying equipment, and promote product development with independent intellectual property rights.

At the same time, enterprises must increase investment in independent innovation, focus on breaking through common key technologies, and take strong independent innovation capabilities as the strategic basis for technological development as a central link in adjusting industrial structure and transforming long-term methods. In addition, relevant enterprises should also take the path of resource-saving development, carry out comprehensive and multi-level energy-saving technological transformation, and vigorously develop drying technologies that apply renewable energy and industrial waste heat.

Drying equipment companies also need to innovate in equipment technology, and operators must also properly select equipment. Some manufacturers say that the operator needs the form of the material, including the size, shape, solid or liquid state; the material characteristics of the material, including density, adhesion and water and its combined state; drying characteristics, including heat sensitivity or heat shrinkage, Surface induration and other properties.

In addition, the operator should also consider the requirements for product drying, including product production: finished product production per unit time, raw material processing or water evaporation calculation; product form: including geometry, crystal luster and structure (such as porous structure) Etc.; product moisture: the level of product moisture; the requirements for uniformity of product drying, and the requirements for product hygiene.

In terms of selection, the selection step is, first, the type of the dryer selected according to the form of the wet material, physical properties, and requirements for product form, moisture, and the like. Secondly, the equipment size, operation method (continuous operation or intermittent operation) and degree of automation should be determined according to the investment ability and the size of the treatment.

Then, according to the drying characteristics of the material and the requirements on the quality of the product, it is determined to use a dry drying in a normal pressure or a vacuum drying zone or a drying in a multi-temperature zone. Again, the heating device is determined according to the heat source conditions and the drying method; finally, the volume of the dryer is estimated according to the treatment, and the product cost is estimated according to the cost of raw materials, equipment and operations.

Some insiders said that although China's drying equipment industry started late, the innovation ability is still insufficient, but relying on the rapid development of China's chemical, pharmaceutical, food and other industries, the market demand for China's drying equipment industry is gradually increasing, more and more New products are constantly on the market.

However, in order to shorten the gap with foreign advanced technology, the domestic drying equipment enterprises should be combined with universities and scientific research institutions in various forms to rationally allocate and utilize resources, and effectively cultivate and develop the innovative capabilities of enterprises. Continued healthy development.
