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.
What are the benefits of a freeze dryer?
The design of the freeze-drying machine automatic control system requires simple operation, starting from the material into the button, quick-freezing vacuum sublimation and drying in one go, prompting the shutdown after the freeze-drying is completed. Relevant temperature and pressure control points should be carefully selected and properly controlled. The correlation between quick freezing, vacuum holding and heating should be properly controlled, and the process curve should be set for different materials.
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.
