Description

Technical Field

[0001] The utility model belongs to the technical field of food detection sample processing, and in particular relates to a sample processing device for food detection. Background Art

[0002] Food testing refers to the process of detecting harmful substances in food in accordance with national standards. It plays a very important role and significance in ensuring public food safety and consumer health, promoting the improvement of food production levels, enhancing food supervision capabilities, and promoting the development of food safety science and technology.

[0003] The current common food testing process mainly consists of the following steps: sampling, sample processing and preparation, and sample analysis and testing. Among them, the food testing sample processing and preparation process mainly includes sample crushing, mixing, filtration, and test liquid extraction.

[0004] The Chinese utility model patent with the patent number CN220650245U discloses a sample processing device for food safety testing. The sample processing device disclosed in the application relates to the technical field of food safety testing and includes: a main body; a support seat, which is arranged directly below the main body and is mutually connected with the main body; a top cover, which is arranged on the upper surface of the main body; a stirring mechanism; and a placement mechanism. The utility model provides a stirring mechanism, which can achieve uniform stirring of the sample. By starting the electric push rod to push the lifting push block to move up and down, the limit rotating rod drives the linkage rotating plate and the stirring slide to rotate through the internal thread that matches the external thread of the lifting push block. At the same time, the two rotating rotating rods slide under the drive of the linkage rotating plate. At the same time, the gear and the main body are engaged through the tooth block to drive the rotating rotating rod to rotate, and drive the stirring plate to crush and stir the sample. At the same time, the sample fragments are raised by the rotation of multiple stirring slides, thereby achieving uniform stirring of the sample.

[0005] However, in combination with the contents recorded in the specification and the drawings, it can be seen that the sample processing device for food safety testing in this application can only crush and mix food samples, and does not have a filtering function, so that the obtained sample mixture contains more impurities, which increases the need for subsequent steps to filter impurities in the sample mixture, making the actual application effect of the food testing sample processing device poor.

[0006] Therefore, in response to the above technical problems, it is necessary to provide a sample processing device for food testing.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0032] like Figures 1 to 7 As shown, a sample processing device for food testing in one embodiment of the present invention includes: a base 1, a crushing and mixing component 2, and a filtering component 3.

[0033] like Figures 1 to 2 As shown, multiple groups of evenly distributed support legs 101 are fixedly mounted below the base 1. The base 1 is supported and fixed by multiple groups of support legs 101, thereby ensuring the support stability of the base 1.

[0034] like Figures 1 to 2 As shown, an assembly support rod 102 is fixedly assembled on the top of the base 1. The assembly support rod 102 plays a role in assembling and fixing the guide rail 207.

[0035] like Figures 1 to 4 As shown, the pulverizing and mixing assembly 2 is assembled above the base 1. The pulverizing and mixing assembly 2 includes a pulverizing and mixing drum 201, which is slidably assembled above the base 1. The pulverizing and mixing drum 201 provides a processing space for pulverizing and mixing food test samples.

[0036] like Figures 1 to 3 As shown, a sleeve ring 205 is sleeved on the outer side of the grinding and mixing drum 201. The sleeve ring 205 plays the role of assembly positioning for the grinding and mixing drum 201.

[0037] like Figures 1 to 4 As shown, a guide slider 206 is fixedly mounted on one side of the collar 205 close to the assembly support rod 102, and a guide rail 207 is slidably mounted on one side of the guide slider 206. The guide rail 207 is fixedly mounted on the side wall of the assembly support rod 102. The sliding cooperation between the guide slider 206 and the guide rail 207 serves as a sliding guide for the collar 205.

[0038] like Figures 6 and 7 As shown, locking bolts 208 are threadedly connected to both sides of the guide slider 206. One end of the locking bolt 208 located inside the guide slider 206 contacts the guide rail 207. By controlling the rotation of the locking bolt 208, the locking bolt 208 contacts the side wall of the guide rail 207, thereby locking and fixing the guide slider 206.

[0039] like Figures 6 and 7 As shown, the side of the collar 205 away from the guide slider 206 is threadedly connected with an assembly bolt 209. By controlling the operation of the assembly bolt 209, the collar 205 is tightened and limited, so that the grinding and mixing drum 201 is clamped and fixed by the collar 205.

[0040] like Figures 2 to 4 As shown, a stirring shaft 202 is rotatably arranged in the crushing and mixing drum 201. The stirring shaft 202 plays the role of assembling, fixing and rotating the multiple groups of crushing blades 203 and the augers 211.

[0041] like Figures 1 to 4 As shown, a grinding motor 210 is fixedly mounted above the assembly support rod 102, and the output shaft of the grinding motor 210 is fixedly connected to the stirring shaft 202.

[0048] like Figures 2 to 5 As shown, a filter cloth cylinder 303 is provided inside the lower filter cylinder 302. The crushed and mixed food test sample is filtered through the filter cloth cylinder 303.

[0049] like Figures 2 to 5 As shown, the inner wall of the lower filter cartridge 302 is fixedly connected with a supporting ring 304, which is sleeved on the outer side of the filter cloth cartridge 303 and arranged below the filter cloth cartridge 303. The supporting ring 304 plays a role in supporting and limiting the filter cloth cartridge 303.

[0050] like Figures 2 to 5 As shown, a drip pipe 305 is fixedly connected to the bottom of the lower filter cartridge 302. The drip pipe 305 guides the filtrate in the lower filter cartridge 302.

[0051] like Figures 2 to 5 As shown, the outer side of the drip tube 305 is integrally formed with a drip valve tube 306. The drip valve tube 306 plays a role of moving limit to the drip valve core 307.

[0052] like Figures 2 to 5 As shown, a drip valve core 307 is rotatably mounted in the drip valve tube 306, and a drip hole is provided in the drip valve core 307. The position of the drip hole is adjusted by controlling the rotation of the drip valve core 307, thereby controlling the conduction state between the drip hole and the drip tube 305.

[0053] like Figures 2 to 5 As shown, one end of the drip valve core 307 outside the drip valve tube 306 is fixedly connected to the control valve plate 308. The drip valve core 307 is rotationally driven by controlling the rotation of the control valve plate 308.

[0054] During use, the locking state of the guide slider 206 is released by rotating the locking bolt 208, and the position of the grinding and mixing drum 201 is adjusted by sliding the guide slider 206 along the guide rail 207. Subsequently, the food sample to be processed can be added to the grinding and mixing drum 201. After addition, the grinding and mixing drum 201 can be moved upward by sliding the guide slider 206. After moving to the mixing position, the guide slider 206 is locked and fixed by rotating the locking bolt 208 in the opposite direction.

[0055] Then, the grinding motor 210 is controlled to rotate, driving the stirring shaft 202 to rotate, thereby controlling the rotation of the multiple sets of grinding blades 203. The rotation of the multiple sets of grinding blades 203 grinds and mixes the food sample in the grinding and mixing drum 201. At the same time, the augers 211 rotate along with the rotation of the stirring shaft 202 to lift and elevate the food sample at the bottom of the grinding and mixing drum 201, so that the food sample in the grinding and mixing drum 201 can be fully ground and mixed.

[0056] When the food is crushed and mixed, the drain hole in the valve core 212 can be connected to the drain valve pipe 204 by rotating the rotating end 213. The mixed solution in the crushing and mixing cylinder 201 can flow along the drain valve pipe 204 to the filter cloth cylinder 303 for filtration. The filtered solution can be discharged through the drip tube 305, thereby completing the crushing, mixing and filtration of the food test sample.
