Drying equipment industry will welcome development

In recent years, freeze-dried drying equipment has developed rapidly in China. With the increasing market demand for freeze-dried equipment and the continuous improvement of the quality requirements of pharmaceuticals, freeze-dried equipment will have considerable development.

The freeze-drying equipment is convenient for controlling the heating temperature and vacuum degree of the divergent phase when the material is dried. In traditional Chinese medicine, it is only limited to the freeze-dried ginseng, antler, yam, and caterpillar fungus, and a large amount of Chinese patent medicine has not yet used freeze-drying technology, which is a big gap with foreign countries.

At present, most domestic food lyophilizer manufacturers are taking imitation roads. Some manufacturers have made major improvements while adopting advanced foreign technologies. So how do freeze-dried devices improve?

First, reduce costs, reduce energy consumption: Some foreign freeze-dried machines do not use stainless steel manufacturing, but use low-carbon steel coating foods can be used to dry the resin, will emit infrared at room temperature. The surface of the shelf is coated with high-performance far-infrared emitting materials to enhance its radiation capability; the surface of the tray is treated to enhance its absorption capacity. The optimization of structure, size and frosting characteristics of the water trap is more practical because the current cost is equivalent to the cost of the freeze-dried box and the power consumption is greater. For a lyophilizer, the heating system only supplements the heat of sublimation. The power consumption should not be too high, but the existing equipment is not satisfactory. The structure should be optimized and the energy consumption should be reduced.

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

Third, to ensure quality and improve performance: Some manufacturers of freeze dryer after installation, can not be put into normal production; some lyophilizers can produce, but high energy consumption. Some components continue to fail and affect normal production. Therefore, the quality of the freeze dryer must be guaranteed. Increasing performance means that new features of the equipment are enhanced in addition to heating rate, pumping rate, temperature uniformity, and vacuum stability.

The vacuum freeze dryer is suitable for the drying of materials such as high-grade raw materials, Chinese herbal medicines, biological products, dehydrated vegetables, chemical products, and pharmaceutical intermediates. 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 the material being oxidized and degraded, eliminate the bacteria in the material, ensure the quality, and the original shape of the material can be well preserved.

At present, China's drying equipment industry has begun to enter a more mature stage, can better meet the actual needs of users in various fields, a large number of professional drying equipment factory, its products are both generic, but also have their own characteristics, which is used for The localization of imported raw materials for drying raw materials and the selection of an ideal dryer conforming to the new GMP provide conditions. In view of the green advantages of vacuum drying equipment, applications are 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 large.
