The development of drying equipment in China

With the progress of the times and the continuous innovation of science and technology, the domestic drying technology has matured The main drying equipment, such as airflow drying, spray drying, fluidized bed drying, microwave drying, freeze drying and other equipment, are basically nationalized, meeting the basic needs of the market For new technology equipment such as impact drying, impinging stream drying, superheated steam drying, heat pump drying and so on, some of them have also been put into operation For the pharmaceutical industry of traditional Chinese medicine, the application of microwave drying technology has its unique role It greatly simplifies and shortens the process and time from the extract of traditional Chinese medicine to the semi-finished products or finished products of preparations, and improves the production efficiency and product quality Compared with developed countries, there is still a big gap between China's drying equipment production and that of other countries However, it is gradually establishing the advantages of domestic equipment, basically realizing the leading role in the domestic market Microwave vacuum drying equipment will become the mainstream of market demand China's drying industry must greatly improve the technical level, improve the drying efficiency, reduce energy consumption, and contribute to the realization of green production In the future, the development of drying equipment in China will show five major trends 1 Comprehensive application of several heat transfer forms to make them play the advantages of various heat transfer forms in different stages of drying, so that the energy consumption of drying equipment is more reasonable; 2 The equipment will be developed to a large scale; 3 The drying equipment will be specialized; 4 It will tend to the development of multi-level and combined drying system; 5 The equipment will be multifunctional Industry insiders said that domestic dryer equipment manufacturers should make full use of the opportunity of China's accession to the WTO, strengthen technical exchanges with foreign countries, absorb the advantages of foreign advanced drying equipment, and make China dry Therefore, China's drying equipment manufacturing enterprises must constantly learn from the international advanced technology, combined with practical experience, explore new technology, develop new technology, take out products to participate in international competition Compared with foreign enterprises, there is a gap in the manufacture of dryer in China When exploring the new development path of drying technology, it is necessary to comprehensively consider energy efficiency, environmental protection and product quality in order to achieve comprehensive, coordinated and sustainable development In order to implement the development strategy of green drying, we should first take the road of resource-saving development, and change the single extensive drying into the combined and intelligent drying Not only the fundamental transformation should be carried out from the drying process, but also the comprehensive and multi-level energy-saving technical transformation should be carried out, and the drying technology of renewable energy and industrial waste heat should be vigorously developed and applied.
