FAQ

How to choose the suitable freeze dryer model?
Please confirm what sample and loading capacity you will do, then we can recommend suitable one for you.
Does the quote include a vacuum pump?
Yes, our freeze dryers all include vacuum pumps, there is no need to purchase a vacuum pump.
What are the differences between multiple series of laboratory freeze dryers?
A Ordinary type: suitable for freeze-drying of bulk (liquid, paste, solid) . conventional substances. B top-press type: suitable for the drying of the material in vials. C manifold type: suitable for different kinds sample. D manifold top-press type: combining the features of top-press and manifold type. E:It is suitable for microbial strains of bacteria, fungi and other microorganisms in ampoule tubes. T:Adopting aubergine and wide-mouth vials for freeze-drying polarized acidic materials. S: With shelf heating function, can do programmable.
What temperature can the partition of the freeze dryer reach?
Our freeze dryer partitions can reach -55℃, -65℃, -75℃, -100℃.
How long will take per cycle process?
Normally takes 20-24hours, including pre-freezing time. Different sample and size takes different time.
Will food produced in a freeze dryer grow mold?
Normally freeze-dried food will not grow moldy, because during the freeze-drying process, the water in the food sublimates into a gaseous state, maintaining the original structure of the raw materials. If moldy occurs, check whether the freeze-drying process time is sufficient and whether the storage method is correct.
Why do freeze dryer need to be pre-frozen?
Because during the freeze-drying process, the water in the sample becomes free water after losing its fixed structure, which can easily lead to structural damage, changes in physical and chemical properties, and reduction in biological activity of the sample. Therefore, the sample needs to be pre-frozen, to ensure freeze-drying quality and stability.
Can the freeze dryer work normally when the ambient temperature is below 0℃?
If the indoor temperature is lower than 9°C, the compressor oil of the freeze dryer will become viscous, which will affect the normal operation of the compressor. When the ambient temperature is lower than 0°C, auxiliary heating equipment can be used to raise the ambient temperature and try to keep the temperature at 5°C to 30°C.

  • Freeze dryer parts and usage analysis
    The freeze dryer consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. It works by freezing the dried item below the triple point temperature and then sublimating the solid water (ice) in the item to water vapor under vacuum conditions, removing it from the item and drying the item.
  • Advantages of freeze drying technology for laboratory freeze dryers
    Drying methods are various, such as drying, boiling, drying, spray drying, and vacuum drying, but ordinary drying methods are usually carried out at temperatures above 0 ° C or higher. The products obtained by drying generally have problems of shrinking size and hardening of the texture. Most of the volatile components are lost, some heat-sensitive substances are denatured and deactivated, and some substances are even oxidized. Therefore, the dried product has a large difference in properties compared with that before drying. The freeze drying technology of the laboratory freeze dryer has the following advantages over the advantages of ordinary drying technology:
