Common drying equipment currently includes belt dryers, drum scraper dryers, hollow blade dryers (blade dryers), vacuum target dryers, double cone rotary vacuum dryers, spray dryers, vacuum ovens, and 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 enhance the ability of independent innovation as the strategic basis for technological development, as the central link to adjust the industrial structure and transform the growth mode. 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 shape of the material, including the size, shape, solid or liquid state; the material properties of the material, including density, adhesion and water content and their 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 yield: finished product output per unit time, raw material processing or water evaporation; product form: including geometry, crystal luster and structure (such as porous tissue) ); product moisture: the level of product moisture; the requirements for product uniformity of 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, it is necessary to determine the equipment scale, operation method (continuous operation or intermittent operation) and degree of automation according to the investment capacity and the amount of processing.
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 amount of processing, 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 and 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 being put 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.

Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
Notable Characteristics:
Cost effective
Requires no consumables
High speed accuracy
Will mark any material (including hardened steel)
Compressed air is not required.
