A vacuum cooling machine

Abstract

The present invention discloses a vacuum cooling machine and the characteristics of the vacuum cooling machine are as follows: a box body and a vacuum cooling unit are connected via an air exhaust pipe, a deflating valve and a vacuum meter are installed on the top of the cabinet, an airproof gate is provide at one side of the box body, a temperature sensor is installed on the right wall of the box body, shelves are arranged inside the box body, good trays are provided on the shelves, and two truckles are provided at the lower end of the shelves. The vacuum cooling unit includes two condensers, a roots pump, a water-ring pump and a vacuum solenoid valve. The roots pump is connected to the bottom of the condensers, the water-ring pump is connected to the right side of the roots pump, and the vacuum solenoid valve is connected to the top of the water-ring pump. The beneficial effects of the vacuum cooling machine are as follows: the vacuum cooling machine has fast cooling speed, short cooling time and uniform temperatures, can avoid biochemical reactions and biological fermentation and ensure a long-term preservation of food, has small occupied area, does not produce any pollutants during the running process, and is safe and hygienic.

Description

technical field [0001] The invention relates to a cooling machine, in particular to a vacuum cooling machine. Background technique [0002] At present, the cooling time of the traditional cooling method is long, and the food is prone to bacterial contamination in the process of high temperature to low temperature, and cannot quickly pass through the bacterial reproduction period, and is prone to high temperature oxidation. It occupies a large area and the cooling temperature is uneven, so a small size, A vacuum cooler with fast cooling, uniform temperature and low energy consumption is particularly important. Contents of the invention [0003] The object of the present invention is to provide a vacuum cooler with small volume, quick cooling, uniform temperature and low energy consumption. [0004] In order to achieve the above object, the technical solution of the present invention is: a vacuum cooler, characterized in that: the box and the vacuum cooling unit are con...
