In recent years, the sales volume of freeze-dried foods in China has become higher and higher, and the freeze-dried foods on the market have emerged in an endless stream. With the continuous expansion of the freeze-dried food market, vacuum freeze-drying equipment has also ushered in a new wave of development. In recent years, China's vacuum freeze-drying equipment is in a period of rapid development, and its development prospects are optimistic.
The vacuum freeze-drying technology firstly rapidly freezes the material, and then heats the material in a vacuum environment, so that the moisture in the material is rapidly sublimated from the solid state into a gaseous state to complete the drying. The lyophilized material retains its original color, taste and nutrients to a large extent. In addition, the vacuum freeze-drying process makes the interior of the material loose and porous, not only crisper, but also has better rehydration.
China's vacuum freeze-drying technology started relatively late. Before 1995, it mainly introduced advanced foreign freeze-drying production lines. Until 1995, China's development of vacuum freeze-drying technology equipment has made gratifying progress, and the process technology has reached the same kind of equipment in foreign countries*.
Earlier, China's vacuum freeze-drying equipment was mainly based on imitation of foreign equipment. But nowadays, with the continuous advancement of technology, domestic production organizations have put forward practical solutions for the improvement of equipment, and the equipment control system has been redesigned, which not only realizes the independent research and development of vacuum freeze-drying equipment, but also improves China. The overall design and control level of large food freeze dryers.
However, whether it is self-developed equipment or imported equipment, the common disadvantages of vacuum freeze dryers are that they are expensive, consume high energy, and recover investment slowly. Therefore, reducing the lyophilization cost is still the main trend of the future development of vacuum freeze dryers. So, how can we effectively reduce the freeze-drying cost? In this regard, many lyophilized equipment manufacturers and research institutions in the world have conducted in-depth research and achieved results.
A lyophilization equipment manufacturing company from Denmark has developed a double cold trap structure. The simultaneous operation of two lyophilizers and two cold traps enables deicing and drying to be synchronized, reducing costs from shortening the freeze-drying cycle. The two technology companies from Denmark have jointly studied the drying method combining freeze drying and air drying. It is reported that this method can reduce the lyophilization cost by 25%. A French-based researcher started with a new freeze-drying technique that reduced the cost of lyophilization by mixing the hygroscopic agent with frozen particles.
In addition to reducing costs, another development of vacuum freeze-drying equipment is the development of continuous freeze-drying equipment. In recent years, successive companies at home and abroad have begun to explore and use continuous vacuum freeze-drying equipment, which simplifies manual operation and management, and is easy to implement automatic control. It is suitable for products with a single variety and large output and sufficient raw materials. However, from the overall market of vacuum freeze-drying equipment, the market penetration rate of continuous vacuum freeze dryers is not high, and the development space is still very large.
In addition, improving hygiene standards is also one of the development directions of the mother vacuum freeze-drying industry. In recent years, as the government and society have paid more and more attention to food safety, domestically imposed stricter requirements on the sterilization and sanitation management of food processing equipment. It is understood that many domestic enterprises have changed the vacuum drying chamber of the original galvanized steel sheet into a stainless steel vacuum chamber. Some enterprises have reduced microbial contamination and prevented food safety by optimizing and innovating the details of each subsystem of the freeze dryer.
As the freeze-dried food market is further opened, the vacuum freeze-drying equipment market is bound to usher in fierce market competition. In this regard, freeze-drying equipment manufacturing enterprises should promptly solve the existing pain points, start from multiple directions, give new equipment capabilities, and enhance the comprehensive competitiveness of equipment.
