Analysis on the Improvement Direction of Chinese Freeze-drying Equipment Technology

At present, China's drying equipment industry has begun to enter a more mature stage, which can better meet the actual needs of users in various fields. There are many professional drying equipment factories, and their products have both versatility and characteristics. However, China's freeze-drying equipment technology has abandoned the imitation and continuous improvement.

In recent years, freeze-drying equipment has developed rapidly in China. With the increasing demand for freeze-drying equipment and the continuous improvement of the quality requirements of pharmaceutical products, freeze-drying equipment will have a great development.

The technical improvement of freeze-drying equipment in China is reflected in three aspects.

The lyophilization equipment facilitates the request for heating temperature and vacuum at different stages of the drying of the material. In terms of traditional Chinese medicine, it is still limited to lyophilization of a small amount of Chinese medicinal materials such as ginseng, velvet, yam, and Cordyceps sinensis. A large number of proprietary Chinese medicines have not been freeze-dried, which is far from the foreign countries.

At present, most domestic food freeze dryer manufacturers are taking imitation roads. Some manufacturers have made great improvements while adopting foreign advanced technology. So how is the freeze-drying equipment improved?

First, reduce costs, reduce energy consumption: Some foreign freeze dryers are not made of stainless steel, but low-carbon steel coated food can be dried with resin, which emits infrared light at room temperature. The surface of the shelf is coated with high-performance far-infrared emitting materials to enhance its radiation ability; the surface of the tray is treated to enhance its absorption capacity. The optimization of the structure, size and frosting characteristics of the water trap is more practical, because its current cost is equivalent to the cost of the freeze-drying box, and the running power consumption is large. For the lyophilizer, the heating system only supplements the sublimation heat, and the power consumption should not be too high, but the existing equipment is not satisfactory, and the structure should be optimized and the energy consumption should be reduced.

Second, the development of continuous freeze-drying equipment: the current production of freeze-drying machines are mostly intermittent products, with the development of industrial technology, the development of continuous freeze-drying equipment, increase the output of freeze-dried products will be an inevitable trend.

Third, to ensure quality improvement performance In practical applications: some manufacturers of freeze dryers have been unable to put into normal production after installation; some freeze dryers can produce, but high energy consumption. There are also some components that are constantly failing and affecting normal production. Therefore, the quality of the lyophilizer must be guaranteed. Improving performance means enhancing the new functions of the device in addition to heating rate, pumping rate, temperature uniformity, and vacuum stability.

The vacuum freeze dryer is suitable for drying high-grade raw materials, Chinese herbal medicines, biological, dehydrated vegetables, chemicals, pharmaceutical intermediates and other materials. . It can be seen that it is widely used in the pharmaceutical industry. The advantage of vacuum freeze-drying is that it can reduce the possibility of oxidative deterioration of the material, eliminate the bacteria in the material, and ensure the quality; the original shape of the material can be well retained.

At present, China's drying equipment industry has begun to enter a more mature stage, which can better meet the actual needs of users in various fields. There are many professional drying equipment factories, and their products are both versatile and have their own characteristics. The localization of imported raw materials for raw materials and the selection of ideal dryers in line with the new GMP provide conditions. In view of the green advantages of vacuum drying equipment, the application is increasingly widespread. In terms of food and drug drying, the demand for vacuum drying equipment of larger specifications will gradually increase, and the market prospect is very huge.
