Microwave drying equipment will stand out in the drying industry

In China, the development of drying equipment industry is slowly derived from some early-rising drying enterprises. This has led to many problems: for example, the geographical location of enterprises is relatively centralized, while technical proficient personnel are relatively scarce. At present, drying equipment enterprises in China are mainly distributed in Henan, Jiangsu, Zhejiang, Shanghai, Liaoning and Heilongjiang, as well as in other regions. There are no drying equipment manufacturers in other areas, and local enterprises that need drying equipment can only be transferred from other places. Competition in drying equipment industry is fierce, some enterprises pay attention to immediate interests, for the incomplete equipment technology put into use in enterprises, resulting in the status of sales without services. Businesses often complain and worry about the choice of dryers. After the reform and opening up, especially in recent years, China's economic growth potential has been effectively released, the supply-demand relationship formed by the shortage economy has changed fundamentally, and the buyer's market has initially formed. Under the pressure of the buyer's market, some enterprises are catching up with the market rather than looking for and exploring the market. The energy of enterprises is focused on the products which have more market demand and mature in the near future. Therefore, in the oven, vibrating fluidized bed, spray dryer and other products, the manufacturers are more concentrated, and the competition is fierce. There are fewer enterprises engaged in drying equipment development in the industry, and the improvement of new products and the introduction of new products mainly rely on mutual imitation.

The innovation ability of drying equipment manufacturers in China is low, and few enterprises can launch new technologies and new products with independent intellectual property rights, which is an important reason for the slow development of drying technology in China. At present, dozens of universities and research institutes in China are engaged in the development and research of drying technology, which is distributed in the east, west, north and south of China, but most of the knowledge achievements have not been effectively translated into real productive forces. In order to become the main body of technological innovation, enterprises should unite directly with these universities and scientific research institutions in various forms, so as to make rational allocation and utilization of resources, and effectively cultivate and develop the innovative ability of enterprises. The advantages of microwave vacuum drying equipment are

1. High-efficiency conventional vacuum drying equipment uses steam to heat, which needs heating from inside to outside. The slow heating speed requires a large amount of coal. The microwave vacuum drying equipment uses electromagnetic wave heating, which does not need heat transfer medium, and directly heating to the inside of the object. The heating speed is fast. The microwave energy of 1 kilowatt can be in 3-5 minutes. By heating the water at room temperature to 100 C, the shortcomings mentioned above are avoided, so the drying cycle is greatly shortened and the energy consumption is reduced. Compared with conventional drying technology, it can increase work efficiency more than four times.

2. Heating is uniform because microwave heating is used to heat the material from inside to outside at the same time. The temperature difference between inside and outside of the material is very small, and the inconsistency between inside and outside heating in conventional heating will not occur, resulting in the effect of expansion, conducive to crushing and greatly improving the drying quality.

3, easy to control, easy to continuous production and automation. Because microwave power can be adjusted quickly and without inertia, it is easy to control in real time, and can adjust the temperature arbitrarily between 40 and 100 degrees Celsius.

4, small spare volume, convenient installation and maintenance 5, good product quality, compared with conventional methods, the quality of processed products has been greatly improved. Microwave equipment has the efficacy of disinfection and sterilization, and the product is safe and hygienic. Long shelf life.

From the characteristics described above, the remarkable economic and social benefits can be seen in energy saving, consumption reduction, product quality improvement, safety and hygiene, and low investment cost of microwave equipment.
