Problems solved by technology

[0005] The object of the present invention is to provide a modified atmosphere packaging machine with an oxygen-consuming secondary deoxygenation structure to solve the problem that the existing modified atmosphere packaging machine proposed in the background technology is not provided with a special secondary deoxygenation link. If the replaced gas in the vacuum chamber still contains oxygen, the packaged product will still contain oxygen, which will lead to poor freshness of the packaged product.

Embodiment example 1

[0029] see Figure 1-4 , a modified atmosphere fresh-keeping packaging machine with an oxygen-consuming secondary deoxygenation structure, comprising a modified atmosphere packaging machine main body 1, a lower module 2 is slidingly arranged in the middle of the modified atmosphere packaging machine main body 1, and the lower module 2 Including the outer shell 3, the inner shell 4 is fixedly installed inside the outer shell 3, the inside of the inner shell 4 is provided with a placement cavity 5, and the top corner of the upper surface of the inner shell 4 is fixedly installed with Oxygen detection sensor 6, a cavity 7 is provided between the inner shell 4 and the outer shell 3, and a cycle deoxygenation mechanism 8 is fixedly installed inside the cavity 7, and the middle position of the cycle deoxygenation mechanism 8 is right The bottom is provided with a waste collection box 9 installed on the lower wall of the outer shell 3, and the middle position of the side wall of the ...

Embodiment example 2

[0038] see image 3 , the waste valve mechanism 18 includes a discharge valve 22 that is rotatably hinged at the lower end of the middle of the horizontal pipe 14, one end of the lower surface of the discharge valve 22 is rotatably hinged with an electric telescopic rod 23, and the other end of the electric telescopic rod 23 Rotation is installed on the mounting plate 24 that is vertically installed at the bottom of the inner casing 4 .

[0039] When the electric telescopic rod 23 of the waste valve mechanism 18 shrinks, the discharge valve 22 is rotated downward to one side of the horizontal pipe 14 to open, so that the oxygen-removing substance reacted with oxygen can be dropped into the waste collection box 9 below the horizontal pipe 14 Inside.

[0040] see image 3 , the blanking valve 22 is a semi-cylindrical tubular structure with the same outer diameter and inner diameter as the horizontal pipe 14, and the lower end of the middle position of the horizontal pipe 14 is...

Abstract

The invention discloses a modified atmosphere fresh-keeping packaging machine with an oxygen consumption type secondary deoxidizing structure, which comprises a modified atmosphere packaging machine main body, a lower module is slidably arranged in the middle of the modified atmosphere packaging machine main body, the lower module comprises an outer shell, an inner shell is fixedly mounted in the outer shell, and a containing cavity is formed in the inner shell; an oxygen detection sensor is fixedly installed at the top corner of one end of the upper surface of the inner shell, a cavity is formed between the inner shell and the outer shell, a circulating deoxidizing mechanism is fixedly installed in the cavity, and a waste collecting box installed on the lower wall of the outer shell is arranged under the middle position of the circulating deoxidizing mechanism; and a deoxidizing material box is fixedly mounted in the middle of one side wall of the outer shell. According to the modified atmosphere fresh-keeping packaging machine, the purpose of deoxidizing can be achieved through chemical reaction between deoxidizing substances and oxygen, and automatic feeding of the deoxidizing substances, automatic flowing of air in the circulating deoxidizing mechanism and automatic discharging of waste obtained after deoxidizing reaction can be achieved.

Description

technical field [0001] The invention relates to the technical field of modified-atmosphere fresh-keeping packaging machines, in particular to a modified-atmosphere fresh-keeping packaging machine with an oxygen-consuming secondary deoxygenation structure. Background technique [0002] Modified atmosphere fresh-keeping packaging machine is a food packaging machine that uses composite gas replacement fresh-keeping packaging technology. [0003] Existing modified atmosphere fresh-keeping packaging machines are not equipped with a special secondary deoxygenation link. If the gas after replacement in the vacuum chamber still contains oxygen, the packaged product will still contain oxygen, which will lead to poor freshness of the packaged product. [0004] Based on this, the present invention designs a modified atmosphere fresh-keeping packaging machine with an oxygen-consuming secondary deoxygenation structure to solve the above problems. Contents of the invention [0005] The...
