Description

Technical Field

[0001] The utility model relates to the technical field of nitrite detection in pickles, in particular to a nitrite detection and extraction device in pickles. Background Art

[0002] At present, kimchi is a lactic acid fermented vegetable product with a unique flavor. It has the advantages of diverse raw materials, simple preparation, low cost, convenient consumption, good sensory quality and suitable taste.

[0003] Among them, there are some food safety issues in the fermentation process of kimchi. The most noteworthy one is nitrite. Nitrite poisoning usually manifests in three types: after nitrite enters the human body, nitrite oxidizes normal hemoglobin in the human blood into methemoglobin, which reduces the oxygen-carrying capacity of the blood, thereby leading to methemoglobinemia; nitrite synthesizes nitrosamines in the body and induces cancer; it causes hypertrophy of the renal gland glomeruli, but nitrite will not cause harm to the human body if it is controlled within a safe range. Therefore, nitrite testing needs to be carried out after kimchi is made.

[0004] When testing for nitrite in kimchi in the market, most people first take out a certain amount of kimchi water from the kimchi jar, then take out the kimchi from the jar, take out a small amount of kimchi, crush it, and finally mix it with the kimchi water after multiple processing steps for testing. This process is very time-consuming and labor-intensive. Therefore, it is necessary to design a new technical solution to solve this problem, which can improve the efficiency of sampling inside the kimchi jar. Utility Model Content

[0005] The purpose of the utility model is to provide a device for detecting and extracting nitrite in pickles, which solves the problems raised in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a device for detecting and extracting nitrite in kimchi, comprising a sampling box, a mounting frame fixedly mounted on one side of the sampling box, a negative pressure pump fixedly mounted on the top of the mounting frame, and an extraction mechanism mounted on the negative pressure pump;

[0007] The suction mechanism includes a material guide pipe connected to and installed at the negative pressure pump outlet port, a hose connected to and installed at the negative pressure pump inlet port, a suction pipe connected to and installed at the other end of the hose, a suction head connected to and installed at the other end of the suction pipe, a motor fixedly installed inside the suction head, and a crushing blade fixedly installed at the other end of the motor shaft.

[0008] As an optional solution of the technical solution of the present application, a battery is fixedly installed at the bottom of the mounting frame, and the battery is fixedly connected to the negative pressure pump and the motor through wires.

[0009] As an optional solution of the technical solution of the present application, a cover is detachably installed on the top of the sampling box, and a rubber pad is sleeved on the side wall of the cover to close the top of the sampling box.

[0010] As an optional solution of the technical solution of the present application, a sealing cover is fixedly installed on the outer wall of the motor, and the side wall of the sealing cover is fixedly installed on the inner wall of the suction head through a bracket, so as to seal the motor.

[0011] As an optional solution of the technical solution of the present application, the side wall of the material guide pipe is connected to and installed with multiple groups of equally spaced branch pipes, and valves are fixedly installed on the multiple groups of branch pipes to control the internal flow of the multiple groups of pipes.

[0012] As an optional solution to the technical solution of the present application, a positioning cover is fixedly installed on the bottom side of the sampling box, and multiple groups of equidistantly distributed sampling cups are placed inside the positioning cover. The multiple groups of sampling cups correspond to the multi-component connecting pipes respectively and can be docked with the multi-component connecting pipes.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The technical solution of the present application is to pick up the suction tube in the suction mechanism, insert the suction head at one end of the suction tube into the kimchi jar, turn on the switch of the negative pressure pump, and quickly take out the kimchi water inside the kimchi jar. A motor is installed inside the suction head, and the driving motor drives the crushing blades to rotate, so that the kimchi attached to one end of the suction head can be crushed. The negative pressure pump delivers negative pressure to the suction tube, so that the kimchi water and kimchi residue can be extracted simultaneously, avoiding the operator's time-consuming and laborious removal of kimchi and kimchi water from the kimchi jar, thereby greatly improving the efficiency of nitrite detection in kimchi.

[0015] 2. The technical solution of the present application is to place multiple groups of equally spaced sampling cups inside the positioning cover, and the multiple groups of sampling cups correspond to the multiple groups of connecting pipes.

[0021] The suction mechanism includes a material guide pipe 2 connected to the outlet port of the negative pressure pump 13, a hose 21 connected to the inlet port of the negative pressure pump 13, a suction pipe 22 connected to the other end of the hose 21, a suction head 23 connected to the other end of the suction pipe 22, a motor 24 fixedly installed inside the suction head 23, and a crushing blade 25 fixedly installed at the other end of the motor 24 shaft. A cover 14 is detachably installed on the top of the sampling box 1, and a rubber pad is sleeved on the side wall of the cover 14 to close the top of the sampling box 1.

[0022] In this technical solution, by picking up the suction tube 22 in the suction mechanism, inserting the suction head 23 at one end of the suction tube 22 into the kimchi jar, and turning on the switch of the negative pressure pump 13, the kimchi water inside the kimchi jar can be quickly taken out. A motor 24 is installed inside the suction head 23, and the driving motor 24 drives the crushing blades 25 to rotate, so that the kimchi attached to one end of the suction head 23 can be crushed. The negative pressure pump 13 supplies negative pressure to the suction tube 22, so that the kimchi water and kimchi residue can be sucked out simultaneously, avoiding the operator's time and effort in taking out the kimchi and kimchi water from the kimchi jar, and greatly improving the efficiency of nitrite detection in kimchi.

Valves 31 are fixedly installed on the multi-component pipes 3 to control the internal flow of the multi-component pipes 3. A positioning cover 32 is fixedly installed on the bottom side of the sampling box 1. Multiple groups of equally distributed sampling cups 33 are placed inside the positioning cover 32. The multiple groups of sampling cups 33 correspond to the multi-component pipes 3 respectively and can be docked with the multi-component pipes 3.

[0024] In this technical solution, when one group of sampling cups 33 is filled with kimchi samples, the valves 31 on the corresponding branch pipes 3 can be closed, and the valves 31 on the other group of branch pipes 3 can be opened to allow another group of samples from the inside of the kimchi jar to be taken again. After measuring and comparing multiple groups of kimchi samples, the accuracy of nitrite detection in kimchi is greatly improved.

[0025] In some technical solutions, a sealing cover 26 is fixedly installed on the outer wall of the motor 24 , and the side wall of the sealing cover 26 is fixedly installed on the inner wall of the suction head 23 through a bracket, so as to seal the motor 24 .

[0026] In this technical solution, when the kimchi water continuously flows from the inside of the suction head 23, the sealing cover 26 is fixedly installed on the outside of the motor 24 to seal the motor 24 and prevent the kimchi water from corroding the motor 24.

[0027] In some technical solutions, a battery 12 is fixedly installed at the bottom of the mounting frame 11, and the battery 12 is fixedly connected to the negative pressure pump 13 and the motor 24 through wires.

[0030] When in use, first open the top cover 14 of the sampling box 1, open the valve 31 on one group of branch pipes 3, close the valves 31 on the other branch pipes 3, and at the same time pick up the suction pipe 22 in the extraction mechanism, so that the suction head 23 at one end of the suction pipe 22 is inserted into the kimchi jar, and the switch of the negative pressure pump 13 is turned on, the kimchi water inside the kimchi jar can be quickly taken out, and the motor 24 is installed inside the suction head 23, and the driving motor 24 drives the crushing blades 25 to rotate, which can crush the kimchi that is attached to one end of the suction head 23, and cooperate with the negative pressure pump 13 to deliver negative pressure to the suction pipe 22, so that the kimchi can be crushed synchronously. The kimchi water and kimchi residue can be extracted, which avoids the operator from taking out the kimchi and kimchi water from the kimchi jar in a time-consuming and laborious manner, thereby greatly improving the efficiency of nitrite detection in kimchi. At the same time, multiple groups of equidistantly distributed sampling cups 33 are arranged inside the positioning cover 32, and the multiple groups of sampling cups 33 correspond to the multi-component connecting pipes 3 respectively. When one group of sampling cups 33 is filled with kimchi samples, the valves 31 on the corresponding branch connecting pipes 3 can be closed, and the valves 31 on the other group of connecting pipes 3 can be opened, so that another group of samples from the inside of the kimchi jar can be newly extracted.
