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.
 
真空冷冻干燥机
产品特点:
真空冷冻干燥机,在真空状态下除去食品中的水分而达到干燥的且的。主要是在高空的状态下,使预先冻结的物料中的水分,不经过冰的溶化,直接以冰态升华为水蒸气被除掉。从而使物料达到干燥状态。真空干燥机可以确保食物中的营养物质,物别是易挥发热敏感性成分不损失。
 
主要构件:
干燥箱,水汽凝结系统,制冷系统,真空系统,加热系统,干燥系统
 
干燥仓
集抽真空与加热干燥功能为一体的密闭容器
 
水汽凝结器
是凝结结升水气的密闭装置,通常位于干燥仓后部,内部有一个较大面积的金属吸附面,从干燥仓物料中升华出来的水蒸气可凝结吸附在其表面上,吸附面的工作温度可达到-45°C -65°C,冷凝器外形是不锈钢或铁制成的圆筒,内部盘有冷凝管,分别与制冷机组相连,组成制冷循环系统。
 
加热系统
冻十机加热系统的作用是对干燥仓内物料进行加热,使物料不断的受热升华,从而达到规定的含水率要求。
 
真空系统
真空系统是由多级真空泵及罗茨真空泵组成,罗茨泵为增压泵不能单独使用,必须先启用真空泵或水环泵。
 
制冷系统
冻干机制冷系统由制冷压缩机组
 
引用领域:
中药饮片,生物,野生蔬菜,脱水蔬菜,食品,水果,化工,药物中间体等。
