China Drying Network At present, domestic researchers have successfully developed a series of vacuum freeze-drying equipment, which has laid a good foundation for the development of vacuum freeze-drying technology in China. With the increasing demand for freeze-dried foods in the international market and the gradual improvement of China’s accession to the WTO and people’s living standards, freeze-dried equipment will have considerable development. In addition to the imitation of domestic freeze- drying equipment , the domestic research and development capability is also improving. Some units have been decoupled from the imitation of foreign models. The suction system uses a low-profile steam jet pump to pump water vapor, eliminating the water trap and refrigeration system. , Lowered equipment prices. However, the common disadvantages of food lyophilizers, whether they are domestic equipment or imported equipment, are high prices, high energy consumption, and slow investment recovery. Lowering costs and reducing energy consumption are the main directions for freeze dryers in the future. Therefore, relevant experts concluded that the research direction and development trend of food freeze dryers are as follows: (1) Reduce costs and reduce energy consumption Some foreign freeze dryers do not use stainless steel, but use low-carbon steel to coat foods with a dryable resin that emits infrared light 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 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. (2) Guaranteeing quality improvement performance In practical applications, freeze dryers of some manufacturers cannot always be put into normal production after installation; some lyophilizers can produce but have 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. (3) Development of continuous freeze-drying equipment Most of the lyophilizers currently produced are batch-type products. With the development of a large number of industrial technologies, the development of continuous freeze-drying equipment and the increase of freeze-dried product output will be an inevitable trend. (4) Improvement of hygiene standards In recent years, Western countries have started implementing HACCP systems in food production companies, and have put forward more stringent requirements for the disinfection and sterilization of food processing equipment and health management. Many Japanese manufacturers have changed the vacuum drying chamber of the original galvanized steel sheet into a stainless steel vacuum chamber, reducing pollution.
