Vacuum freeze-dried Western Europe mainly uses imported dehydrated vegetables. Dehydrated vegetables can be added directly to convenience foods, and can also be used as raw materials for further processing. Drying methods of dehydrated vegetables include hot air drying, far-infrared drying, microwave drying and puffing drying. Vacuum freeze-drying is a drying method in which the cut material is frozen in a sealed container, the contained water is changed into ice, and then heated under a high degree of vacuum to directly sublimate ice crystals inside the material into water vapor. Compared with other drying methods, the vacuum freeze-drying technology has the advantages of less heat consumption, good reduction properties, little change in nutrient composition, color, taste, shape, etc. after drying, avoiding the discoloration caused by the traditional dehydration method, Loss of taste, loss of components, dry shrinkage and other defects, and high product quality. At present, dehydration vegetables in the world are sending vacuum-dried dehydrated vegetables to dovetails. The disadvantage is that the equipment is more complex and the processing cost is expensive. However, the product after vacuum freeze-drying is light in weight (losing 95% to 97% of water content) and is easily transported. After drying, water-deficient bacteria cannot grow and multiply. After being packaged, it can be stored at room temperature for a long period of time, up to 1 to several years. Its storage and transportation costs are low, which compensates for the high cost of processing fees to some extent. Modified Atmosphere Modified Atmosphere Refrigeration is a refrigerating method of controlling the gas composition of the storage environment of fruits and vegetables on the basis of cold storage, so as to obtain better results of storage of fruits and vegetables. Atmosphere refrigeration has been recognized as the most advanced fruit and vegetable preservation in the world. storage. Compared with ordinary cold storage, the storage period is extended by 1 time. The delivery period of fruits and vegetables after delivery can be extended to 21 to 28 days, which is 3 to 4 times that of ordinary cold storage, so that the fruits and vegetables are kept brittle, the nutrient composition and hardness, color, and weight There is little difference between the rationale and the new picking status, and it has an excellent storage effect. The products stored in the air-conditioned storeroom must be stored in and out of the storehouse, and large-scale, long-term storage of fruits and vegetables (such as products sold in off-season and products used in off-season) should be stored in a special air-conditioned refrigerator. Storage environment for gas composition detection and regulation. However, the air-conditioned warehouse has a higher cost than an ordinary cold storehouse, and it is necessary to increase the price of the complete set of air-conditioning equipment. Decompression, storage, decompression, depot, and fresh-keeping are also known as pressure storage, preservation, or vacuum storage and preservation. They are the development of controlled atmosphere storage. They place fruits and vegetables and other fresh foods in sealed warehouses (containers), and store them during the cooling process. The air in the (container) is withdrawn and decompressed and reduced in oxygen. As the pressure continues to decrease, some gases harmful to the storage (such as ethylene) are also reduced or almost disappeared. This has created favorable results for the long-term storage and preservation of fruits and vegetables. condition. In contrast to controlled atmosphere storage, decompression storage only changes the total air content and density in the storage environment and does not change the air composition and the combination ratio. In the normal operation, the vacuum decompression library can simultaneously and continuously complete the vacuum pre-cooling and decompression refrigeration process, which reduces the storage process. Since the stored fruit vegetables in the library do not need to be airtightly packed, the ozone can be conveniently disinfected and decontaminated in the library. Bacteria and mildew have met the four major elements of low temperature, high humidity, low oxygen, and high-efficient anti-corrosion during storage of fruits and vegetables. The storage and fresh-keeping period is 1 to 2 times longer than ordinary cold storage and preservation. The decompressed refrigerator can not only store fresh fruit and vegetables, meat, aquatic products and flowers, but also store advanced biological products and archives, films, cultural relics, etc., which should not be stored under normal temperature and pressure. At present, the decompression warehouse cost is basically similar to that of the air-conditioning warehouse.

Alternating Pressure

Alternating pressure devices typically utilize multiple bladders to facilitate routine patient turning. These devices may also assist the nursing staff to move the patient to change bedding and move the patient out of bed.

Low Air Loss

Low air loss devices are typically powered with blowers that run continuously. Air is allowed to escape through the device in specific areas designed to provide further comfort and treatment of the patient. The blower maintains constant air pressure and inflation of the device.

Static Overlay Mattresses

Static overlay mattresses are filled with a specific volume of air once prior to use. These devices are often used for the prevention and treatment of pressure ulcers (bed sores).
