Technical Field

The invention relates to the field of food, in particular to vacuum heat insulation type food low-temperature cooking equipment.

Background

The food sold in the market often needs the processes of bagging, vacuumizing, sealing and the like. After bagging and sealing, expansion often occurs due to the rise of air temperature, so that the vacuum effect is poor. In addition, sometimes the food needs to be heated after being bagged in the food processing process, and the phenomenon is more remarkable.

Disclosure of Invention

The invention aims to provide vacuum heat insulation type food low-temperature cooking equipment, which can heat and vacuumize food packages at the same time.

In order to achieve the purpose, the invention adopts the following technical scheme:

a vacuum heat insulation type food low-temperature cooking device comprises a U-shaped heat insulation cavity and a cover plate, wherein the cover plate is covered on the upper part of the heat insulation cavity and forms an inner space with the heat insulation cavity; a heater is arranged at the bottom of the inner space, and a filter screen is erected above the heater; the side wall of the bottom of the heat insulation cavity is hermetically penetrated with a wire channel pipe, and a wire connected with the heater penetrates out of the wire channel pipe to be connected with the outside;

the upper part of the inner wall of the left side of the heat insulation cavity is provided with an air suction hole which is communicated with an air suction hose arranged in the inner space; the bottom of the left side of the heat insulation cavity is communicated with a suck-back prevention cavity through an opening, and the side wall of the upper part of the suck-back prevention cavity is communicated with the vacuum pump through a pipeline with a pressure gauge; the bottom of the suck-back prevention cavity is communicated with a liquid discharge pipe with a valve;

the bottom of the heat insulation cavity penetrates through a drain pipe with a valve in a sealing mode, one end of the drain pipe is communicated with the inner space, and the other end of the drain pipe is communicated with the outside.

An observation window is arranged on the cover plate.

The cover plate is provided with a handle.

The cover plate is internally vacuum.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the vacuum heat insulation type food low-temperature cooking device of the present invention comprises a U-shaped heat insulation chamber 1 and a cover plate 5, wherein the cover plate 5 is covered on the upper part of the heat insulation chamber 1 and forms an inner space with the heat insulation chamber 1; a heater 7 is arranged at the bottom of the inner space, and a filter screen 8 is erected above the heater 7; the side wall of the bottom of the heat insulation cavity 1 is hermetically penetrated with a wire passage pipe, and a wire connected with the heater 7 penetrates through the wire passage pipe to be connected with the outside;

the upper part of the inner wall of the left side of the heat insulation cavity 1 is provided with an air suction hole 11, and the air suction hole 11 is communicated with an air suction hose arranged in the inner space; the bottom of the left side of the heat insulation cavity 1 is communicated with a suck-back prevention cavity 2 through an opening, and the side wall of the upper part of the suck-back prevention cavity 2 is communicated with a vacuum pump 4 through a pipeline with a pressure gauge; the bottom of the suck-back prevention cavity 2 is communicated with a liquid discharge pipe 3 with a valve;

the bottom of the heat insulation cavity 1 is hermetically penetrated with a drain pipe 9 with a valve, one end of the drain pipe 9 is communicated with the inner space, and the other end is communicated with the outside.

The cover plate 5 is provided with an observation window.

The cover plate 5 is provided with a handle 6.

The cover plate 5 is internally evacuated.

The side wall of the heat insulation cavity 1 penetrates through a water inlet pipe 10 with a valve in a sealing mode, one end of the water inlet pipe 10 is communicated with the inner space, and the other end of the water inlet pipe is communicated with the outside.

When the present invention is used, the cover plate 5 is opened, a packaging bag containing food therein and having an opening is placed on the screen 8, and the opening of the packaging bag is hermetically connected to the suction hole 11 of the heat insulating chamber 1 through a suction hose (not shown). Starting a vacuum pump 4 to pump air, and simultaneously vacuumizing the food bag when the vacuum pump 4 vacuumizes the heat insulation cavity 1; the injected water (can be injected through the water inlet pipe 10 or directly injected), the heater 7 is electrified, the food in the packaging bag can be heated, in the heating process, the food is inevitably expanded and gas is possibly discharged, the vacuum pump 4 can still vacuumize the food, and some food liquid which is accidentally pumped enters the suck-back preventing cavity 2 and cannot enter the vacuum pump 4 to cause damage. The heat insulation cavity 1 can effectively insulate the liquid in the heat insulation cavity due to vacuum, so that the heating efficiency is higher. And after heating, separating the food package from the air suction hose and sealing the opening, thus finishing the food processing process. The substance liquid and the heating water can then be discharged through the drain pipe 3 and the drain pipe 9.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
