lab equipment freezer technology has a wide range of applications in the fields of bioengineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products. So what are the advantages of freeze-drying technology? Xiaobian is here to introduce you one by one.
1. In the process of lab equipment vacuum freeze dryer, the growth of microorganisms and the action of enzymes cannot be carried out, so the original sex can be maintained. Since the drying is carried out in a frozen state, the volume is almost constant, the original structure is maintained, and concentration does not occur.
2. Since the drying is carried out under vacuum, there is very little oxygen, so some easily oxidizable substances are protected.
3. Drying can exclude more than 95-99% of water, so that the dried product can be preserved for a long time without deterioration.
4. The dried material is porous and spongy. After adding water, it dissolves quickly and completely, and immediately restores the original trait.
5. lab equipment vacuum freeze dryers are carried out at low temperatures and are therefore particularly suitable for many heat sensitive materials. Such as protein, microorganisms and the like will not degenerate or lose biological vitality. Therefore, it is widely used in medicine.
6. When drying at low temperature, some volatile components in the material are lost little, suitable for some chemical products, medicines and foods to be dry.

lab equipment freezer energy saving measures from freeze-drying process
1. Shape processing and concentration adjustment of materials
For solid materials, if there is no excessive shape requirement, the heat transfer mass transfer area can be increased by cutting treatment, thereby speeding up the freeze-drying rate and reducing the freeze-drying time; if the shape of the material is high, cutting is not allowed, and puncture can be taken. The treatment is to facilitate the escape of water vapor inside the material, and the lyophilization rate is enhanced by strengthening the mass transfer process.
For liquid raw materials, if there are more colloidal substances, when the concentration is higher, appropriately lowering the concentration of the materials will help to increase the freeze-drying rate. However, the material concentration should not be too low, otherwise the energy consumption will be increased due to too much moisture removed, and the water vapor diffusion pores may be clogged and the freezing rate may be lowered. If the liquid material has a high water content, such as a water content of more than 80%, it should be concentrated as much as possible before lyophilization to increase the drying rate.
2. Vacuum freeze drying system
For vacuum freeze-drying systems, energy-saving measures should be taken from three aspects: maintenance of vacuum, refrigeration system and drying system. First, the low vacuum is beneficial for the outward diffusion of heat, but at the same time the resistance to outward diffusion of water vapor increases; the result is reversed at high vacuum. The higher the vacuum, the greater the energy required to maintain the vacuum. Therefore, choosing the right degree of vacuum is conducive to reducing consumption. Secondly, reducing the condensation temperature, increasing the evaporation temperature, adopting a scientific and reasonable heat transfer method, adopting an automatic system, and achieving comprehensive energy utilization are all conducive to the reduction of energy consumption in the freeze-drying process.
3. Improve heating method and heating temperature
The control of the heating temperature includes temperature control of the frozen layer and the dried layer. In the case of ensuring that the material does not melt, the higher the temperature of the frozen layer, the better. Under the premise of not denaturation of the material or disintegration of the dried layer structure, a higher dry layer temperature is used as much as possible to shorten the drying time.
4. Control pre-freezing speed and tray loading
When studying the vacuum freeze-drying process, it was found that the pre-freezing speed affects the formation of ice crystals, and the faster freezing rate of ice crystals is smaller, which is not conducive to sublimation, long dehydration time, but dissolves quickly after drying. The slower freezing rate is larger for ice crystals, which is good for dry dehydration, but slower after drying. In addition, the thinner the thickness of the material piled up on the unit area tray, the faster the heat transfer and mass transfer rate, and the shorter the drying time. However, if the thickness of the material is thin, the amount of material dried per batch per unit of freeze-drying area is small, which is unfavorable for increasing the unit freeze-drying area and unit time production. Therefore, choosing the right tray loading and cooling rate can reduce energy consumption.
