Freeze Dry Machine
There are two types of vacuum freeze dryer at Hawach, one is a desktop freeze dryer and the other is in-situ freeze dryer. To use a desktop dryer, you need to first freeze the material in the cold trap and then take it out and put it into the vacuum drying room. And the in-situ freeze dry machine, just as the name indicates, is more convenient since you just need to place the material in the machine, and it will automatically freeze and dry without taking materials from one chamber to another.
Hawach’s two types of freeze dry machine have different use occasions. Desktop one is mostly used in the laboratory, a lab freeze dryer. It is relatively smaller and cheaper than the in-situ dryer. And in-situ freeze dry machine is mostly used in industry, and sometimes in the commercial market and pilot-scale testing.
Freeze dry machine is suitable for heat-sensitive materials, and its application involves food, herbs, cosmetics, chemistry, biology, etc. The machine’s working principle makes the dried materials remain the same in appearance and properties.
From cold trap temperature, Hawach has six types of freeze dry machine for you to choose from -50. -55, -56, -60, -75, -80 degrees centigrade. You can also choose desktop or in-situ for different occasions. Furthermore, a freeze dry machine with or without heating function, using electric or silicone oil for heating, and different drying room (Hawach has five here) is also available at our company.
