Drying equipment is widely used in pharmaceutical, chemical and other industries. At the same time, with the continuous improvement of industrial production technology and consumer requirements, also put forward higher technical requirements for drying equipment. Drying equipment is widely used in petrochemical enterprises, serving petrochemical enterprises, so it is greatly affected by the industry economy. This year, the overall economic operation of the petrochemical industry is not optimistic, which is a challenge for the drying equipment industry. The real impact is small enterprises, large enterprises have not been greatly affected, some large enterprises only reduce the profit space some, the output value does not decline.
  For example, microwave vacuum dryer is a new type of microwave energy application equipment combined with microwave energy technology and vacuum technology. It has a series of advantages of microwave and vacuum drying. It overcomes the disadvantages of long cycle and low efficiency in conventional vacuum drying. In the process of general material drying, it can increase the efficiency of 4~10 times compared to the conventional method. . With the advantages of high dry yield, good quality and low processing cost, microwave vacuum drying equipment is a new high technology product which integrates various disciplines such as electronics, vacuum, mechanics, thermodynamics, program control and so on. It is the physical change, internal and external heat and mass exchange and the moisture under the vacuum in the drying process. A new technology and technology developed on the basis of in-depth study of the migration process.
  The scientific and technological content of drying equipment initially played a leading role. Since 2004, the development situation of the national chemical industry has been steadily driven, the market situation of the drying equipment is stable, and the production enterprises have generally obtained good operating performance. At present, the remarkable characteristic of drying equipment serving the chemical industry is the increasingly prominent role of technical content. This is very different from the past selling products, mainly based on price competition. Among them, some dry equipment have high technical content and pay more attention to the development of new products. On the contrary, some enterprises with low technology content and weak development ability of new products and new technologies have begun to decline.
     After more than ten years of development, the drying equipment industry in China has begun to enter a more mature stage, and can better meet the actual needs of users in various fields. In view of the "green" advantages of the vacuum drying equipment, the application is becoming more and more widely. In food and drug drying, the demand for larger specifications of vacuum drying equipment will gradually increase, the market prospect is very huge.
  Experts say that energy efficiency, environmental protection and quality of products must be considered comprehensively in order to achieve a comprehensive, coordinated and sustainable development in the exploration of a new development road for drying technology. In order to implement the development strategy of high efficiency and green drying, the first step is to take the road of resource-saving development, and change the single extensive drying into combination and intelligent drying. We should not only transform the drying process fundamentally, but also carry out comprehensive and multi-level energy-saving technological transformation, and vigorously develop the drying technology for the application of renewable energy and industrial waste heat.
  Compared with the current drying oven method and spray drying method, the vacuum continuous drying method has many unique advantages, which can guarantee the quality of the product is much higher than that of the other drying methods. The vacuum continuous drying equipment and technology have the advantages of low temperature drying, less destruction of effective components, easy dissolution and absorption, drying and sterilization, so as to ensure high effective components, high aseptic index and good oral absorption.
 
  The industry has pointed out that domestic enterprises have accelerated the study of vacuum drying technology, some enterprises have made breakthrough progress, to a certain extent, reduce energy consumption, reduce pollution, and bring more benefits and value for the society.
 
  Although there is a certain gap between the domestic drying equipment production and the developed countries at present, the advantages of domestic equipment are being gradually established, and the domestic market is basically dominated. The vacuum drying equipment will become the mainstream of the market demand. The domestic industry must greatly improve the technical level, improve the drying efficiency, reduce the energy consumption, and contribute to the green production.
