A household freeze dryer is a device that can directly change the water in food from solid to gas to produce dehydrated and dried products.
The operation of the freeze dryer is very simple, and it can be started by pressing a button, which is suitable for home use. It freezes very quickly, and fruit slices are generally ready in ten hours, which is much faster than natural air drying. Moreover, it can operate in a low-temperature vacuum state, without destroying the nutritional components of the ingredients. Vitamins, enzymes, etc. can be preserved, and the nutritional retention rate can reach more than 90%. In addition, the freeze-dried ingredients have a complete structure and taste very good. It can freeze dry many things, such as fruits, vegetables, meat, medicinal materials, pet food, candy, etc.
The process of making freeze-dried candy is as follows: Spread the candy to be freeze-dried on the material tray of the freeze dryer and put it into the freeze-drying chamber. Turn on the refrigeration system and quickly freeze the candy to about minus thirty to fifty degrees to make it completely frozen. Then, in a vacuum environment, use the heating system to turn the ice crystals in the fruit directly into water vapor, which is pumped away by the vacuum pump. The temperature and pressure should be controlled during this process to avoid damaging the nutrition and structure of the candy. After the sublimation drying is completed, the pressure and temperature are further reduced to remove the residual moisture and ensure that the moisture content is less than 5%. Finally, take out the freeze-dried candy and wrap it with sealed, moisture-proof packaging materials.
Freeze dryers can keep food fresh and extend its shelf life while retaining nutrition, taste and color. Freeze-dried food is small in size and light in weight, easy to store and carry, and suitable for travel, camping and other occasions. Home freeze dryers can also be used to make a variety of unique freeze-dried foods, such as freeze-dried rose tea, freeze-dried yogurt, freeze-dried soup, etc.
