Purple sweet potato chip low-temperature drying equipment

Abstract

The invention provides purple sweet potato chip low-temperature drying equipment. The equipment comprises a box, a box cover, a liner, wheels, a motor, a driving wheel, a driven wheel, inner gears, racks, an air extracting device, a one-way valve and a deaerating device; the box cover and the rear side of the box are connected together in a hinged mode, the wheels are installed on the bottom of the liner, and the liner is arranged in the box, so that a containing portion is formed; the motor shaft and the driven wheel shaft penetrate an inner cavity of the box and extend into the inner wall ofthe left side of the box, the four inner gears are in pin-connection with the motor shaft and the driven wheel shaft in pairs and located on the left and right sides of the inner cavity of the box, and the racks are connected to the outer walls of the left and right sides of the liner in a welded mode and meshed with the inner gears on the left and right sides, so that an oscillating portion is formed; the one-way valve abuts against the deaerating device and is installed in the right side wall of the box, and the deaerating device is installed in the left side wall of the box, so that an airdrying portion is formed; materials are placed in the liner, the oscillating portion drives the liner to conduct reciprocating motion back and forth in the inner cavity of the box, and the air dryingportion drives air without oxygen to flow through the liner, so that moisture in the materials is taken away.

Description

technical field [0001] The invention relates to an anthocyanin extraction and preprocessing device, in particular to a low-temperature drying equipment for purple potato slices. Background technique [0002] Purple sweet potato is rich in anthocyanins. In chemical experiments or cell experiments in the laboratory, anthocyanins have shown powerful antioxidant functions. Many people have conducted research on this, and many related scientific papers have been published, and it has been confirmed that the antioxidant damage of cells is related to the occurrence of many chronic diseases, such as cancer, aging, etc.; It shows a strong inhibitory effect; for experimental animals such as mice, anthocyanins also show a certain resistance to artificially induced tumors. [0003] At present, the anthocyanins in berries are mainly extracted by freeze-drying technology, the water-containing material is frozen below the freezing point, the water is frozen into ice, and then the ice is d...

AI Technical Summary

Problems solved by technology

Compared with other potatoes, the water content of purple potatoes is already low, but for the skin and seeds suitable for freeze-drying technology, the water content of purple potatoes is very high, which greatly increases the difficulty and cost of drying
