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....

I began to hear that when I was lyophilized, I was puzzled by hot drying, but it seems a little impossible to freeze-dry. Let us look at how freeze drying is applied to the technology of vacuum dryers. After reading it, I must be able to lift the doubts in everyone's mind....

For the freeze dryer, everyone is familiar, but the freezing principle is certainly not very familiar, today Xiaobian will explain the principle of freeze-drying curve of freeze dryer, let's learn together!...

There are two traditional methods for the treatment of moisture in the gas source. One is that the adsorbent absorbs the water in the gas source, and the resulting equipment is an adsorption dryer; the other is by lowering the gas temperature to below the dew point temperature. The water in the air is condensed into a liquid and then separated to reduce the water content in the gas source, and the resulting equipment is a freeze dryer....
