What is a Vacuum Freeze Dryer? How does it work? 
Freeze dryer and lyophilizer are synonymous names for the same equipment. A freeze dryer executes a water removal process typically used to preserve perishable materials, to extend shelf life or make the material more convenient for transport. Freeze dryers work by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to sublimate.

According to customer's production capacity, the size of the design layout in the vacuum container 3-11 layer of conveyor belt, through continuous feeder will need to dry raw materials under the condition of vacuum continuous feeding, and uniform cloth in a dry, because the material in the drying process continuously turn, accelerate the evaporation rate and time, at the same time ensure product uniformity in the process of drying, the drying temperature in the 20-150 ºC, material from entering the dryer to about 20-80 minutes after drying can be adjustable.

The dried products can be crushed under vacuum if the crushing process is needed, avoiding dust flying, increasing product yield and solving pollution problems.The dried products can be discharged continuously through vacuum continuous feeder and vacuum reclaimer, and the organic solvent can be recovered at the same time, which solves the problem of environmental protection and increases the benefit of solvent recovery.

1. Complete continuous feeding and discharging under vacuum state, vacuum crushing, achieve dryness and meet GMP hygiene requirements

2. The drying temperature is controllable (40ºC ~ 180ºC), the heat-sensitive materials are variable, the solvent can be recovered 95% of the solvent, and the oxidized materials can be vacuum dried without oxidation

3.20 ~ 80 minutes continuous discharge, product yield reaches 99%

4. The highly viscous material does not stick to the belt (the guide belt is teflon), and the crystal material does not damage the crystal shape after drying

5. PLC automatic programming control system, high degree of automation, greatly reduce the cost of human operation

6. Operating cost is one third or less of that of similar drying equipment

7. CIP automatic online cleaning system, the cleaning effect is complete and fast, in line with GMP requirements


Working principle:
1.Powder: materials from the hopper into the transfer bin → the transfer bin falls freely into the distributor and are distributed on the teflon guide belt (the fabric thickness and speed can be adjusted).

2.Liquid: the material is continuously and evenly coated on the moving guide belt by the feeding agitator into the 2 swing distributor. Under the guide belt, the heating zone is continuously guided to provide heating and drying, and the material on the guide belt is being transported.During the feeding process, water content continuously evaporates, and the steam is quickly removed by vacuum → the material reaches the cooling zone and cools down/becomes brittle rapidly. Then it enters the screw conveyor and is transported to the pulverizer for crushing. The number of mesh (20-200) is adjustable.

3.Water evaporation: the water of the material is continuously evaporated by vacuum pump.Water is quickly frozen by the condenser, and the condensing liquid is discharged or collected automatically.

4. Cleaning: CIP automatic online cleaning system, diversified cleaning methods, can be used to dry the equipment after a full range of cleaning, cleaning effect is complete, fast, in line with GMP requirements.
