Probiotics Freeze Dryer
Probiotics Freeze Dryer
Probiotics are accepted by larger and larger amount of people nowadays, it is used in various ways. Probiotics are difficult to be stored. There are many technical problems in the existing products, such as the easy death of live bacteria and unstable bacteria count, which lead to the short shelf life and unstable quality of probiotics products.
Due to this properties of probiotics, during the manufacturing process, only freeze dryer could be used. The FD process happens under a low temperature, which suits the heat-sensitive substance’s request. During the FD process, malignant variation of probiotics, and infection of bacteria will not be carried out. Therefore probiotics’ original properties will not be affected by this process. Lyophilized probiotics powder is porous, spongy, dissolve quickly and completely.
While talking about how to choose a freeze dryer, it is quite obvious that the traditional type of freeze dryer can not meet the requirements for processing probiotics. However, medical freeze dryer costs too much, it is important to design, and produce a suitable freeze dryer used for health care products like probiotics.
Pre-freeze drying is carried out in situ to reduce the tedious operation of the drying process; Silicone oil as a circulating medium, shows a good control accuracy in high temperature, shelf temperature difference is less than 1℃, to ensure uniform drying effect and qualified rate of finished products. The temperature of the shelf is adjustable and controllable, and the rising or cooling rate of the drying process is controllable. Also, the freeze drying process is optimized. Both manual and automatic control mode are available.
The automatic production and system correction makes the FD process of probiotics reduces the cost.
