Vacuum Cooler
Product features and main components
Vacuum cooler is not a cold storage equipment, but cooling processing equipment, it is mainly based on the physical attribute that the boiling point of water reduces as the pressure drops. During the process, pre-cooling materials are vacuumized in vacuum tank, and the surface moisture will start to boil and evaporate when pressure reaches a certain numerical value, meanwhile, taking away plenty of heat. Through these steps, so that the material to achieve rapid cooling effect.
Main feature:
- Fast cooling time : generally takes 20-30 minutes to cool down to the required temperature for refrigerated storage.
- Clean and uniform cooling : for the surface moisture evaporates and takes away internal heat in a vacuum environment, material will achieve uniform cooling inside- out, so as to restrain the growth of bacteria.
- High quality of the thin-layer drying effect : it can heal material epidermal damage, retaining the color, smell, taste, and extending storage period.
- High degree of automation , safe, reliable, and wide applied.

真空预冷机
产品物点及主要构件
真空预冷机不是冷藏设备,而是冷却加工设备。主要依据水的沸点随着压力下降而降低的物理属性,将预冷的物料置于真空槽子中抽真空,当压力达到一定数值时,物料表面的水分开始沸腾蒸发,并带走大量的热。从而使物料达到快速降温的效果。
主要特点:
- 冷却时间快:一般20-30分钟即可降到物料冷藏所需的温度
- 干净卫生,冷却均匀:真空环境下可以杀死并抑制细菌的滋生。且由于是物料表面水分蒸发带走自身的热量,实现由内而外的均匀降温。
- 薄层干燥效应品质高:有治愈保鲜物表发损伤,可保有物料本身的色,香,味,延长贮存期。
- 自动化程度高,安全性可靠,应用方面广
主要构件:
真空系统

Vacuum freeze drier
Features :
Vacuum freeze drier, removing moisture in the food in vacuum situation to dry it. In the state of high vacuum, freeze driver lets the water of pre-freezing material turned into water vapor and removed directly under ice state without melting. During this process, vacuum drier can keep the nutrients in the food, especially for the volatile heat sensitive ingredients.
Main Components:
Drying oven, vapor condenser, cooling system, vacuum system, heating system, control system
Drying Oven:
A closed container integrated vacuum with drying function.
Vapor Condenser :
a sealing device for water vapor condensation and sublimation, usually located in the rear of drying oven and a large oven can be adsorption surface area inside. The vapor distilling from drying oven can be adsorbed in the metal surface, whose temperature will down to -45°C~ -65°C.While the condenser is a cylinder made of stainless steel or iron with inner condensing tube, which connects with the refrigerating units respectively and forms refrigeration cycle system.
Heating System :
The function of freeze drier heating system is to heat the material in drying oven, reaching constant sublimation so as to achieve the specified requirement for moisture content.
Vacuum System:
It is composed by multi-stage vacuum pump or water ring pump and Roots vacuum pump. For the roots pump is booster pump that can not be used alone, the vacuum pump or water ring pump must be firstly enabled.
Cooling System:
Freeze drier cooling system is composed by refrigeration compressors.
Application:
Chinese herbal medicine, creature, wild vegetable, dehydrated vegetable, food, fruit, chemical engineering, pharmaceutical intermediate, etc.
