There are many advantages of freeze dryers, so we are not surprised that freeze dryers are widely used today. Yes, in fact, the application of freeze dryer covers many fields such as bioengineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products. Today we briefly introduce the application of freeze dryer in medicine and bioengineering....
How to choose the degree of vacuum in the drying process of the freeze dryer? It is a scientific method to determine the appropriate pressure for freeze drying by the vapor pressure of ice. ...
The quality requirements of the freeze-drying machine for freeze-dried products are: constant biological activity, uniform appearance and color, full shape, firm structure, fast dissolution rate and low residual moisture. ...
Dehydrated food: As the name suggests, it is to remove foods with low water content or low water content; there are many ways to process dehydrated foods, including drying, lyophilization, microwave drying, vacuum low-temperature frying, drying, etc., to remove fresh food moisture. Dry foods can be called dehydrated foods. Therefore, dehydrated vegetables contain freeze-dried vegetables....
Because J refers to the vacuum, it means that there is no space state of gas, but it is actually a vacuum environment that does not exist. Therefore, we generally say that the vacuum of a vacuum freeze dryer refers to a space of one D, and the atmospheric pressure is lower than the gas state, that is, the density of gas molecules in the space is lower than the density of gas molecules in the atmospheric pressure of the region....
