Second hand freeze dryer - Freeze dryer - High price recycling of various modelsFreeze drying of drugs includes two parts: Western medicine and traditional Chinese medicine. Western medicine freeze-drying has achieved certain development in China, and many larger pharmaceutical factories have freeze-drying equipment. In terms of injections, freeze-drying technology is widely used, which improves the quality and storage period of drugs, bringing benefits to both doctors and patients. There are not many varieties of freeze-dried drugs, high product prices, and poor drying processes. In terms of traditional Chinese medicine, it is limited to the freeze-drying of a small amount of traditional Chinese medicine, such as ginseng, yam, and so on. A large number of traditional Chinese patent medicines and simple preparations have not yet adopted the freeze-drying process, which has a large gap with foreign countries.Freeze drying (hereinafter referred to as freeze-drying) is a method of preserving substances by first freezing them into a solid state, and then sublimating the water from the solid state to a gaseous state to remove the water. In the process of compressed air drying, freeze-drying is achieved by reducing the temperature of the compressed air to remove moisture from it. The working principle of a freeze dryer (refrigerated dryer) is the same as that of a refrigerator. After the compressed air passes through the frozen compressed air pipeline, the temperature of the compressed air drops to the required temperature to meet the drying requirements.There are various drying methods, such as sun drying, boiling drying, drying, spray drying and vacuum drying, but common drying methods are usually carried out at temperatures above 0 ℃ or higher. The products obtained from drying generally have problems of volume reduction and texture hardening. Most of the volatile components are lost, and some heat sensitive substances undergo denaturation and deactivation. Some substances even undergo oxidation. Therefore, there is a significant difference in the characteristics of the dried product compared to before drying. The freeze-drying method is basically carried out below 0 ℃, that is, in the frozen state of the product. Only when the residual moisture content of the product is reduced in the later stage, can the product be raised to a temperature above 0 ℃, but generally not exceeding 40 ℃. Under vacuum conditions, when water vapor sublimates directly, the drug remains in the frozen ice shelf, forming a sponge like porous structure. Therefore, its volume size remains almost unchanged after drying. Before reuse, simply add injection water and it will dissolve immediatelyLiangshan Jiyoupin Machinery Equipment Co., Ltd. is engaged in second-hand pharmaceutical equipmentUsed chemical equipment, used grain and oil processingequipment, as well as variousequipmentRelated factory spare parts, all second-hand equipment are imported, domestic products.Our main business is second-hand equipment,PP environmental protection equipment processing, environmental purification tower, PP storage tank, stainless steel storage tank, fiberglass storage tank, various models of drying machines, dryers, reaction kettles and other processing customization, engaged in the maintenance, recycling, dismantling, installation and purchase of second-hand equipment such as starch equipment, flour equipment, agricultural equipment, feed equipment, emulsification equipment, beverage equipment, food equipment, drying equipment, alcohol equipment, environmental protection equipment, plastic environmental protection equipment, biomass pellet equipment, biological fermentation equipment, chemical storage tanks, filter presses, dryers, centrifuges, freeze dryers, tablet presses, ovens, condensers, heat exchangers, packaging machines, mixers, crushers, granulators, kneaders, dispersers, crushers, extruders, cleaning machines, filters, etc.Our company has a large reserve of vacuum freeze dryers, including food type freeze dryers and pharmaceutical type freeze dryers, with a complete range of models and sizes.

During the freeze-drying process, the growth of microorganisms and the action of enzymes cannot be carried out, so the original characteristics can be maintained. Due to drying in a frozen state, the volume remains almost unchanged, maintaining the original structure and preventing concentration. Due to the presence of water in the material in the form of ice crystals after pre freezing, inorganic salts dissolved in water are evenly distributed throughout the material. During sublimation, dissolved substances in water precipitate, avoiding the phenomenon of surface hardening caused by inorganic salts carried by the migration of internal moisture to the surface in general drying methods. After drying, the substance is loose and porous, appearing sponge like. It dissolves quickly and quickly after adding water, almost immediately restoring its original shape. Due to the drying process being carried out under vacuum with very little oxygen, some easily oxidizable substances are protected. Drying can remove over 95% to 99% of moisture, allowing the dried product to be preserved without deterioration. Due to the frozen state of the material and the low temperature, the temperature requirement for the heating source is not high. A heater at room temperature or low temperature can be used to meet the requirements. If the freezer and dryer are separated, the dryer does not need to be insulated and there will not be a lot of heat loss, so the utilization of thermal energy is very economical.
