The bacterial strains includeBacteriaactinomycetesFour major categories: yeast and mold，It's microbiology andlife sciencesThe basic materials for research areFood, industry, agriculture, andmedicineclassIn the fieldWidely used. Because the collection, distribution, storage, and use of bacterial strains require low temperatures, it is extremely inconvenientThe freeze-drying machine for biological products produces freeze-dried powder of bacterial strains, which canSolving bacterial strainslong period of timeStorage and transportationConvenient for resurrection.

By vacuum freeze-drying methodIt is a standard method for long-term preservation of bacteria, yeast, fungi, viruses, and rickettsia.Before the freeze-drying treatment of bacterial strains, the biological product freeze-drying machine needs to cultivate microorganisms through a culture medium, collect bacterial cells and add protective agents, and thenDivide the bacterial suspension into sterile containers in a sterile environment.After pre-treatment and packaging of the bacterial strains, they enter the biological product freeze-drying machine compartment for ultra-low temperature freezing and crystallization into a solid state. It is necessary to operate under the guidance of a technical engineer to prevent the formation of large ice crystals during pre freezing, which may cause bacterial cell death. After the pre freezing is completed, a drying sublimation and analytical drying stage is carried out. The temperature control range, heating rate, and vacuum control values are set under the guidance of a technical engineer. The biological product freeze-drying machine is used to remove more than 99% of the moisture and obtain freeze-dried powder of bacterial strains with very little water content. Then seal the packaging as soon as possible and store it away from light.

SFD freeze-drying machine engineers provide freeze-drying solutions and freeze-drying process technology for bacterial strains, assisting enterprises in bacterial strain processing and production, and supplying high-quality bacterial strain freeze-dried powder.
