Description

Technical Field

[0001] The invention relates to the technical field of pretreatment, in particular to a multifunctional pretreatment device for food detection. Background Art

[0002] Food testing is a key means of ensuring public health. It can detect whether there are harmful substances in food, such as microorganisms, chemical contaminants, allergens, excessive additives, etc., to prevent food safety incidents.

[0003] Food needs to be pre-processed before testing. The food needs to be crushed and then made into a solution form that is easy to measure.

[0004] In the existing technology, the pretreatment of food before testing is mostly done manually using simple tools to grind the food, add reagents to the ground food and filter it into a solution. This is time-consuming and labor-intensive when encountering foods with a relatively hard texture, thus affecting the efficiency of food testing. Therefore, a multifunctional food testing pretreatment device is proposed to solve the above problems. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides a multifunctional food pretreatment device for testing, which has the advantages of being able to quickly grind foods with a relatively hard texture, thereby ensuring the efficiency of food testing. It solves the problem in the existing technology that pretreatment before food testing is mostly done manually using simple tools to grind the food, add reagents to the ground food, and filter it to make a solution. This is time-consuming and labor-intensive when encountering foods with a relatively hard texture, thus affecting the efficiency of food testing.

[0007] (2) Technical solution

[0008] The technical solution of the present invention to solve the above technical problems is as follows: a multifunctional food detection pretreatment device comprises a lower cylinder, the bottom wall of the inner cavity of the lower cylinder is fixedly connected to the filter cartridge, the left side of the lower cylinder is provided with a discharge pipe connected to the interior thereof, the top of the lower cylinder is fixedly connected to the upper cylinder located above it by bolts, the top of the upper cylinder is fixedly connected to the cover body by bolts, the left side of the upper cylinder is provided with a water injection pipe extending to the top of the filter cartridge, the inner wall of the upper cylinder is fixedly connected to the isolation ring, the top of the cover body is rotatably connected to the main shaft extending to the interior of the upper cylinder, and the bottom of the main shaft is fixedly connected to a shaft rotatably connected to the isolation ring. The top of the isolation ring is provided with a clamping component that is symmetrically distributed on the left and right and extends to the bottom thereof, and the bottom of the clamping component is provided with the same second grinding disc that is adapted to the first grinding disc, a feeding cavity that extends to the bottom of the first grinding disc is opened inside the main shaft, and an inlet that is connected to the feeding cavity is opened on the front side of the main shaft, a pressing component that extends into the inside and adapts to the feeding cavity is provided on the top of the main shaft, the outside of the main shaft is fixedly connected to the first pulley, the top of the cover body is provided with a driving component that is transmission-connected to the first pulley, and the bottom of the first grinding disc is fixedly connected to a stirring head that is movably connected to the second grinding disc and extends into the filter cartridge.

[0009] The beneficial effects of the present invention are:

[0010] The multifunctional food testing pretreatment device injects reagents into the lower cylinder and the filter cartridge through the water injection pipe, pulls up the material pressing assembly, and then places the food into the feeding chamber through the inlet, so that the material pressing assembly is lowered. The material pressing assembly can apply downward pressure to the food in the feeding chamber, so that the food is in close contact with the top of the second grinding disc, and the driving assembly is started, and then the main shaft is driven to rotate by the first pulley. At this time, the first grinding disc is rotated relative to the second grinding disc, so that the food and the top of the second grinding disc are rubbed, and the fine particles generated by the friction enter between the first and second grinding discs due to the pressure of the material pressing assembly on the food. Because the second grinding disc is tightly attached to the bottom of the first grinding disc due to the pressing assembly, the food is thoroughly ground and finally falls into the reagent in the filter cartridge through the gap between the outer rings of the first and second grinding discs. In the above process, the main shaft rotates and then drives the stirring head to rotate, so that the fine food residue and the reagent are fully mixed to form a solution form that is convenient for measurement and discharged through the discharge pipe. It has the advantage of being able to quickly grind foods with relatively hard textures, thereby ensuring the efficiency of food testing.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the clamping assembly includes a threaded rod, a first spring, a gasket and a nut. The top of the isolation ring is slidingly connected to a threaded rod that is symmetrically distributed on the left and right and extends to the bottom thereof. The bottom end of the threaded rod is fixedly connected to the same second grinding disc. The outer side of the threaded rod is sleeved with a first spring located at the top of the isolation ring. The outer side of the threaded rod is sleeved with a gasket located at the top of the first spring. The outer side of the threaded rod is threadedly connected to a nut that fits tightly with the top of the gasket.

[0013] The beneficial effect of adopting the above further scheme is that, by opening the cover body, by rotating the nut, and by adjusting the pressing force of the nut on the first spring, the elastic force of the first spring makes the second grinding disc close to the first grinding disc through the threaded rod, and then the fitting force between the first grinding disc and the second grinding disc can be adjusted, thereby adjusting the coarseness of the food after grinding.

[0014] Furthermore, the pressing assembly includes a bending rod, a first baffle, a pressure block, a second baffle and a second spring. The top of the main shaft is slidably connected to a bending rod extending to the feeding chamber and inside the bending rod. The outside of the bending rod is fixedly connected to the first baffle located above the feeding chamber. The left end of the bending rod is fixedly connected to a pressure block adapted to the feeding chamber. The right end of the bending rod is fixedly connected to the second baffle located inside the main shaft. The top of the second baffle is provided with a second spring located outside the bending rod and inside the main shaft.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the bending rod is pulled up, and then the pressure block moves upward in the feeding chamber, and at the same time the second spring is compressed to produce elastic deformation, and the food is placed in the feeding chamber through the entrance, thereby loosening the bending rod. The bending rod slides downward under the elastic force of the second spring to restore the elastic deformation, and downward pressure can be applied to the food in the feeding chamber through the pressure block, so that the food is in close contact with the top of the second grinding disc.

[0016] Furthermore, the drive assembly includes a motor, a second pulley and a synchronous belt. The top of the cover is provided with a motor, the output end of the motor is fixedly connected to the second pulley, and the outer side of the second pulley and the first pulley are provided with the same synchronous belt.

[0017] The beneficial effect of adopting the above further solution is that the motor drives the second pulley to rotate, and then drives the first pulley to rotate through the synchronous belt, thereby driving the main shaft to rotate.

[0018] Furthermore, a sealing ring adapted to the isolation ring is fixedly connected to the outer side of the first grinding disc.

[0019] The beneficial effect of adopting the above further solution is that the isolation ring places the food crumbs into the upper part of the isolation ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The clamping assembly 10 includes a threaded rod 101, a first spring 102, a gasket 103 and a nut 104. The top of the isolation ring 7 is slidably connected to the threaded rod 101 that is symmetrically distributed on the left and right and extends to the bottom thereof. The bottom end of the threaded rod 101 is fixedly connected to the same second grinding disc 11. The outer side of the threaded rod 101 is sleeved with the first spring 102 located at the top of the isolation ring 7. The outer side of the threaded rod 101 is sleeved with the gasket 103 located at the top of the first spring 102. The outer side of the threaded rod 101 is threadedly connected to the nut 104 that fits tightly with the top of the gasket 103.

[0029] Open the cover 5, turn the nut 104, and adjust the pressing force of the nut 104 on the first spring 102. The elastic force of the first spring 102 causes the second grinding disc 11 to be in close contact with the first grinding disc 9 through the threaded rod 101. Then, the contact force between the first grinding disc 9 and the second grinding disc 11 can be adjusted, thereby adjusting the coarseness of the food after grinding.

[0030] The pressing assembly 13 includes a bending rod 131, a first baffle 132, a pressure block 133, a second baffle 134 and a second spring 135. The top of the main shaft 8 is slidably connected to the bending rod 131 extending to the feeding chamber 12 and inside the feeding chamber. The outer side of the bending rod 131 is fixedly connected to the first baffle 132 located above the feeding chamber 12.

[0031] Pull up the bending rod 131, and then move the pressing block 133 upward in the feeding chamber 12, and at the same time compress the second spring 135 to produce elastic deformation, and put the food into the feeding chamber 12 through the insertion port 18, thereby releasing the bending rod 131. The bending rod 131 slides downward under the elastic force of the second spring 135 to restore the elastic deformation, and the pressing block 133 exerts downward pressure on the food in the feeding chamber 12, so that the food is in close contact with the top of the second grinding disc 11;

[0032] The driving assembly 15 includes a motor 151, a second pulley 152 and a synchronous belt 153. The motor 151 is provided on the top of the cover 5. The output end of the motor 151 is fixedly connected to the second pulley 152. The second pulley 152 and the outer side of the first pulley 14 are sleeved with the same synchronous belt 153.

[0033] The motor 151 drives the second pulley 152 to rotate, which in turn drives the first pulley 14 to rotate through the synchronous belt 153, thereby driving the main shaft 8 to rotate;

[0034] A sealing ring 17 adapted to the isolation ring 7 is fixedly connected to the outer side of the first grinding disc 9;

[0035] The isolation ring 7 is used to place food crumbs onto the isolation ring 7 .

[0036] Working principle:

[0037] Step 1: Inject the reagent into the lower cylinder 1 and the filter cartridge 2 through the water injection pipe 6, pull up the bent rod 131, and then move the pressing block 133 upward in the feeding chamber 12. At the same time, the second spring 135 is compressed to produce elastic deformation, and the food is placed into the feeding chamber 12 through the insertion port 18. The bent rod 131 is then released. The bent rod 131 slides downward under the elastic force of the second spring 135 to restore the elastic deformation. The pressing block 133 then applies downward pressure to the food in the feeding chamber 12, so that the food is in close contact with the top of the second grinding disc 11.

[0038] Step 2: Start the motor 151, which drives the second pulley 152 to rotate, and then drives the first pulley 14 to rotate through the synchronous belt 153, thereby driving the main shaft 8 to rotate. At this time, the first grinding disc 9 is rotating relative to the second grinding disc 11, so that the food rubs against the top of the second grinding disc 11, and the fine particles generated by the friction enter between the first grinding disc 9 and the second grinding disc 11 due to the downward pressure exerted by the pressure block 133 on the food in the feeding chamber 12. The elastic force of the first spring 102 makes the second grinding disc 11 close to the first grinding disc 9 through the threaded rod 101, and the food is thoroughly ground. Finally, the food falls into the reagent in the filter cartridge 2 through the gap between the outer rings of the first grinding disc 9 and the second grinding disc 11;

[0039] Step 3: During the above process, the main shaft 8 rotates and then drives the stirring head 16 to rotate, so that the food residue and the reagent are fully mixed to form a solution that is convenient for measurement and discharged through the discharge pipe 3.
