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.

  • How To Control The Pressure Of The Pilot Freeze Dryer?
    Pilot freeze dryer is common in daily life. Air freeze-drying technology, referred to as freeze-drying, is also known as sublimation air-drying. Freeze-drying is a specific method of pre-freezing water-containing materials and then subliming them in a vacuum state to obtain air-dried objects. Freeze-dried objects have basically unchanged original biological and chemical properties, and are easy to store for a long time. After soaking in water, it can be restored to the form before freeze-drying, and its original biochemical properties can be maintained. Therefore, freeze-drying technology is widely used in various fields such as industrial chemistry and medical equipment.
  • Use Of Food Freeze Dryer
    Food Freeze Dryer is currently a more advanced method of material dehydration, the technology is water-containing substances frozen at low temperatures, and then make the water in the vacuum state directly sublimation, and condensation method to capture the sublimation of water vapour, to achieve the purpose of material dehydration and drying. After the food freeze dryer of the material, its physical, chemical and biological state is basically unchanged, the material in the volatile components and heat denaturation of the loss of nutrients is very small, after freeze drying of the material is porous, its volume is basically the same as before drying. Therefore, after adding water, due to the large contact area, it can be recovered very quickly and has a longer preservation period in the sealed container.
  • What about the refrigerant leak in the laboratory freeze dryer?
    Refrigerant, also known as refrigerant, is commonly known as snow in some areas of the South. It is a working substance that continuously circulates in a refrigeration system and undergoes its own state change to achieve refrigeration. The refrigerant absorbs heat in the evaporator by heat of a cooling medium (water or air, etc.), and transfers heat to the surrounding air or water in the condenser to condense.
