Description

Technical Field

[0001] The utility model relates to the technical field of fruit processing, in particular to a vacuum fruit freeze-drying low-temperature dehydrating machine. Background Art

[0002] The vacuum fruit freeze-drying low-temperature dehydration machine is an advanced food processing equipment specially used to dehydrate fresh fruits under low temperature and vacuum environment to produce freeze-dried fruit products. This equipment combines the principles of low-temperature freezing and vacuum drying, and can effectively remove moisture from fruits in a very short time, while maximally retaining the original nutrients, color, flavor and shape of the fruits. The fruits are fixed during the dehydration process to prevent direct contact between the fruits and the fruit plate, which affects the taste after freeze-drying.

[0003] Traditional dehydrators first wash, peel, and core the fruit, cut it into slices, strips, or blocks of appropriate size, and place it in a fruit plate for fixation. The fruit is quickly frozen at a temperature of -20°C to -40°C to form ice crystals, and then vacuum dried to reduce the pressure in the drying chamber to sublime the ice crystals into water vapor. Hot air or other forms of heating are used to remove the remaining moisture, and the equipment is turned off to allow the fruit to cool naturally.

[0004] The above-mentioned traditional vacuum freeze-drying equipment has a high investment cost, including equipment purchase, installation and operation costs. Traditional equipment may have limitations in processing certain fruit varieties or fruits of specific shapes and sizes. During the drying process, due to differences in fruit density and morphology, the product may be dried unevenly, affecting the quality of the final product. Utility Model Content
