Vacuum cooling machine capable of solving food safety hygienic problems

Abstract

The invention discloses a vacuum cooling machine capable of solving food safety hygienic problems. The vacuum cooling machine comprises a tank body with a charging opening and a discharging opening, and a sealing door for sealing the charging opening and the discharging opening, wherein a waterproof door lock for locking the sealing door at the charging opening and the discharging opening is arranged on the tank body and the sealing door; a guiding and positioning mechanism is arranged on the tank body; a waterproof electrical control cabinet with electrical apparatus elements, and a waterproof junction box for leading out wires buried in the tank body are arranged on the side surface of the tank body; a temperature sensor connected with the electrical apparatus elements is arranged in thetank body; an electric control tank with a buzzer, which is rotatably connected with the tank body, is hung on the outer side of the tank body; a controller which cooperates with the electric controltank to facilitate loading and unloading and a heat exchanger connected with the tank body are arranged on the side surface of the tank body; a jet device with a steam inlet and a steam outlet communicates with the heat exchanger and the tank body; and the vacuum cooling machine also comprises a repressing mechanism which is connected with the tank body and is used for balancing the pressure difference in the tank body after cooling is completed so that the sealing door is convenient to open. According to the vacuum cooling machine disclosed by the invention, charging and discharging are convenient; the vacuum cooling machine is convenient to operate, and good in waterproof sealing properties; the waterproof grade can achieve an IP68 grade; the protection grade of steam washing can achieve an IP69K grade; the number of bacterial colonies is small; and the vacuum cooling machine is safe and hygienic.

Description

technical field [0001] The invention relates to the technical field of food machinery, in particular to a vacuum cooler capable of solving food safety and hygiene problems. Background technique [0002] Vacuum cooling is based on the principle that vaporized water molecules have higher energy than liquid water molecules, so water must absorb the latent heat of vaporization when it is vaporized, and its latent heat of vaporization increases with the decrease of boiling point. Put the material into a closed vacuum box that can withstand a certain negative pressure and is pumped by a suitable vacuum system. As the vacuum degree in the vacuum box increases continuously, the boiling point temperature of water decreases continuously, and the water becomes easy to vaporize. Only by absorbing heat from the processed object itself, the processed object can be cooled rapidly. [0003] During the long-term cooling process of the vacuum cooler, the surface is exposed to the air. If the...

Problems solved by technology

[0003] During the long-term cooling process of the vacuum cooler, the surface is exposed to the air. If the surface is not cleaned and sterilized in time after the cooling is completed, bacteria and other microorganisms on the surface will multiply at a multiple speed, threatening food safety. The waterproof level of the vacuum cooler is relatively low, and there are many dead spots. When cleaning steam sterilization, the number of bacteria residues is large, and the problem of poor sealing will cause damage to the vacuum cooler and the waterproof electric control box, affecting the box. The normal operation of the cabinet reduces the service life of the cabinet and affects food safety.
