IntroductionThe domestic freeze-dryer is composed of a refrigeration system, vacuum system, heating system, and electrical instrument control system. What are the benefits of domestic freeze-dryers? Let's take a look below:
No content provided for translation.Lyophilization is performed at low temperatures, making it particularly suitable for many thermolabile substances, such as proteins and microorganisms, which do not denature or lose their biological activity. Therefore, in the medical...Please provide the Chinese content that needs to be translated into American English.The product is widely applied.
TwoDue to the drying process being conducted in a frozen state, the volume remains almost unchanged, preserving the original structure and preventing any concentration phenomena.
No content provided for translation.The dried substance is loose and porous, resembling a sponge. When water is added, it dissolves rapidly and completely, almost immediately restoring its original properties.
No translation needed, as there is no Chinese content provided..Due to the drying being carried out under vacuum with oxygen.Please provide the Chinese content that needs to be translated into American English.Some oxidizable substances were thus protected.
FiveDuring low-temperature drying, the loss of volatile components in the substance is minimal, making it suitable for drying some chemical products, pharmaceuticals, and food.
SixDuring the freeze-drying process, the growth of microorganisms and the action of enzymes cannot occur, thus preserving the original properties. The drying process removes moisture, allowing the dried product to be preserved for a long period without spoilage. The application fields of domestically produced freeze-drying machines.
Freeze-drying is a method that involves pre-freezing hydrated materials and then drying them by sublimation under vacuum to obtain dried products. Items processed through freeze-drying retain their original biological and chemical characteristics, making them easy to store for long periods. Upon rehydration, they can revert to their original dried form and maintain their inherent biochemical properties. Consequently, freeze-drying technology is widely applied in the chemical industry and the production of biological products.
Prior to freeze-drying, the items to be dried should be placed in a low-temperature freezer or liquid nitrogen to ensure they are fully frozen solid before proceeding with the freeze-drying process.
The car mobile host is connected to the vacuum pump through a vacuum pipe, and the connection externally uses a medium-intermediate standard screen. Inside the screen, there is a two-port macro sealing nipple changer. Before the connection, a vacuum grease can be applied to the nipple changer, and a longer screen is used for rain.
The power socket for the vacuum pump is located on the right side of the mainboard; connect the power cable of the vacuum pump properly.
Check the vacuum pump to ensure it has been properly filled with vacuum pump oil; it must not operate without oil. The oil level must not fall below the white line on the oil gauge. Before a second use, please refer to the vacuum pump operation manual in detail.
Above the cold trap of the mainframeThe "n" magnetic sealing fitting is designed to ensure cleanliness. When used once, simply apply a thin layer of grease to the fitting, align it with the glass sealing ring, gently rotate a few times, and it will securely seal with the cattle seal.
Lyophilizers are widely used in the pharmaceutical, biologic, chemical, and food industries. Freeze-drying technology is particularly suitable for thermosensitive substances such as antibiotics, vaccines, blood products, enzymes, hormones, and other biological tissues.
