Food vacuum freeze dryer, abbreviated as food freeze dryerIt is the process of low-temperature freezing of food substances containing water into a solid state based on the principle of sublimation, and then directly sublimating them into a gaseous state in a vacuum environment to obtain freeze-dried food with very little water content. The nutritional components, color, aroma, taste, and shape of the original food substances remain basically unchanged. Kiwi fruit is a highly valuable nutritional fruit, as it is difficult to preserve and traditional processing can damage its nutritional components. In order to better preserve the nutritional and trace element substances of kiwifruit, the application of food vacuum freeze-drying machine in kiwifruit freeze-drying slice processing has successfully solved the existing problems.

Kiwi freeze-dried slicesIt is the process of pre cleaning and slicing kiwi fruit materials, which are then subjected to low-temperature drying in a food vacuum freeze dryer-45After freezing crystallization at ℃, it is stored in the material compartment of the food freeze dryer45PAUnder the following vacuum environment, perform primary and secondary drying to remove the moisture in kiwi slices by directly sublimating them into a gaseous state without passing through a liquid, resulting in water content3~5%Freeze dried kiwi slices. Because kiwi slices dry at low temperatures, they contain a large amount of thermosensitive substances such as vitaminsChlorophyllbeta-caroteneWhen it is preserved, the enzyme reaction is basically stopped, so the original nutrients are greatly preserved. During the vacuum freeze-drying process, the material is continuously dried in a high vacuum and oxygen free environment, so the material is hardly oxidized. After freeze-drying, the moisture of the material is removed to obtain a porous substance, making it easy to rehydrate and restore its original properties, fully preserving nutrients and trace element substances, and maintaining basic shape and color.

FZG Food Vacuum Freeze Drying MachineIt has been widely used in the processing and production of kiwi freeze-dried slices and kiwi freeze-dried powder in Guizhou, Yunnan, Sichuan and other places. At the same time, during the non kiwi picking season, it can be used for freeze-drying lemon slices, wild mushrooms, shiitake mushrooms, mangoes, peaches and Chinese medicinal materials.
