Probiotics vacuum freeze dryer is currently more advanced drying technology, compared with the traditional freeze dryer has a great improvement. In drying probiotics and maintaining the activity of probiotics has a unique advantage, at present, a large part of probiotic products are freeze-dried using freeze-drying machine for vacuum freeze-drying and storage.
However, the freeze-drying process still
faces problems such as loss of activity, long freeze-drying cycle, and
difficulty in discharging, which makes the application of vacuum freeze-dryer
in the production of probiotics subject to certain limitations.
In recent years, a variety of freeze-drying
related technologies have emerged, especially the vacuum low-temperature drying
technology, both the advantages of spray vacuum freeze dryer, but also to solve
the spray freeze dryer can not solve the problem, at the same time, the energy
consumption is much smaller than the spray freeze dryer, and the output is much
Vacuum Belt Dryer is a widely used equipment in the field of industry and food processing for converting liquid or high humidity materials into powder or dry form. Drying probiotics through a vacuum belt dryer has the following key benefits:
1. Maintaining Activity: Vacuum drying is a
gentle drying method that can help maintain the activity of probiotics. High
temperatures and prolonged drying may kill or reduce the activity of
probiotics, but vacuum drying is usually able to be performed at relatively low
temperatures and with a short drying cycle, which helps to keep probiotics
2. Long-term storage: Drying probiotics
allows for easier long-term storage. The low humidity environment prevents
bacterial growth and decomposition, thus extending the shelf life of probiotic
3. Continuous and convenient discharging: continuous feeding and continuous discharging under vacuum, and the integration
of drying, crushing and granulating process, convenient receiving.
4. Convenient transportation: dried
probiotic products are usually lighter and easier to pack and transport. This
helps to reduce transportation costs and ensure that the product is not damaged
5. Powder or granule form: Vacuum belt dryers
can dry probiotics into powder or granule form, which makes them easier to mix
with other products, such as the manufacture of nutraceuticals, dairy products,
medicines or foods.
It is believed that in the future, vacuum low-temperature continuous dryer will gradually replace most of the including spray vacuum freeze dryer, boosting the high-speed development of probiotic drying industry chain.
