KFD-Series Industrial Vacuum Freeze Dryer
The pilot-scale vacuum freeze dryer is not only suitable for the exploration and optimization of the freeze-drying process to prepare for large-scale production, but also for small batch production. It is an ideal equipment for enterprises and scientific research institutes to conduct pilot and small batch production. It is generally divided into two types: one is a heating system that uses electric heating as the heating medium. One is a system that uses silicone oil as the heating medium. In terms of appearance, there are square cabins and round cabins.
Features
Features：
1. Pre-freezing and drying are two separated structures, which is able to freezeand dry at the same time. This can improve the efficiency of freeze-dryingand shorten the time of freeze-drying.
2.Aerospace grade aluminum alloy partition material, double-sided radiationheating, radiation rate of more than 90%, good temperature uniformity.
3.High efficiency mixed refrigerant medium, low freezing point and high boilingpoint, high heat transfer efficiency, long service life.
4.The drying curve optimization control algorithm can control the heating rateand vacuum degree value of the products in the drying stage.
5.Patented gas diversion design and control technology, strong water captureability, high drying efficiency.
6.Flexible manual + automatic control mode, manual for exploring process,automatic for mass production.
7.Accurate sensor calibration function to ensure the accuracy of processparameters in long-term use.
8.Can set user leveland password, decentralized operation management.
9.Accept customization, to meet customers'requirements.
