[0002] Food testing refers to the inspection of the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products based on basic theories and various technologies such as physics, chemistry, biochemistry, etc., in accordance with established technical standards (such as international and national food hygiene / safety standards) to ensure that the product quality is qualified. Its purpose is to protect the health of consumers, maintain market order, and promote the healthy development of the food industry. Before testing some liquid foods, the samples need to be treated to avoid some liquid solutes from sinking to the bottom, causing errors in the test results. Therefore, a sample pretreatment device for food testing is needed.

[0010] Two side travel grooves are arranged on one side outer wall of the top box, the feed pipe and the discharge port respectively pass through the side travel grooves and extend to the outside of the processing box, and a mounting top plate is fixedly installed at the top center position of the material receiving processing box.

[0011] As a further description of the above technical solution:

[0012] A guide rail is fixedly installed on the inner wall of the bottom surface of the material receiving and processing box, and two adsorption magnetic seats with slide grooves are slidably installed on the guide rail. The magnetic poles of one end of the two adsorption magnetic seats are different. Adsorption magnetic plates are fixedly installed on the inner walls of both sides of the processing box, and the other end of the adsorption magnetic seat is different from the magnetic pole of the adsorption magnetic plate.

[0013] As a further description of the above technical solution:

[0014] The interior of the mounting top plate is provided with a rotation hole, the longitudinal mixing assembly is rotatably mounted in the rotation hole, the longitudinal mixing assembly comprises a first mounting shaft, and the exterior of the first mounting shaft is fixedly mounted with a limited rotation rib and a plurality of longitudinal mixing blades.

[0015] As a further description of the above technical solution:

[0016] The limiting turning rib is rotatably connected to the turning groove arranged on the inner side of the turning hole, a top gear is fixedly installed on the top of the first mounting shaft, a meshing worm is fixedly installed on the bottom end of the first mounting shaft, a meshing rack is laterally fixedly installed inside the top box, and the top gear and the meshing rack are meshed and connected with each other.

[0017] As a further description of the above technical solution:

[0018] The transverse mixing assembly comprises a second mounting shaft, a meshing worm gear is fixedly mounted at the middle position of the second mounting shaft, transverse mixing blades are fixedly mounted on the outer surface of the second mounting shaft, and the meshing worm and the meshing worm gear are meshedly connected with each other.

[0019] As a further description of the above technical solution:

[0020] Two irradiation and sterilization components are arranged on the top of the material receiving and processing box, and the irradiation and sterilization components are used to detect the synchronous sterilization treatment of food processing. The irradiation and sterilization components include two mounting top plates, and the two mounting top plates are fixedly mounted on the top surface of the material receiving and processing box, and a lamp holder shaft is rotatably mounted between the two mounting top plates.

[0021] As a further description of the above technical solution:

[0022] Both ends of the lamp holder shaft are fixedly installed with a set torsion spring, one end of the set torsion spring is fixedly connected to the outer wall of one side of the top plate, a germicidal lamp holder is fixedly installed on the outside of the lamp holder shaft, an ultraviolet lamp board is fixedly installed on the outer wall of one side of the germicidal lamp holder, and touch pressure plates are fixedly installed on the inner walls of both sides of the top box, and the touch pressure plate is located on one side of the ultraviolet lamp board.

[0023] The present invention also discloses a sample pretreatment process for food testing, comprising the following steps:

[0024] S1. When pre-processing food, add liquid food into the material receiving and processing box through the feeding pipe. At this time, the driving motor can be directly started to drive the reciprocating screw to rotate. The reciprocating screw can drive the material receiving assembly to move back and forth inside the processing box. At this time, the liquid food will continue to shake in the material receiving assembly;

[0025] S2. During this process, the top gear can mesh with the meshing rack and rotate, and the first mounting shaft drives the plurality of longitudinal mixing blades to rotate, so as to stir and mix the food well. Meanwhile, the meshing worm can also drive the second mounting shaft with the meshing worm gear to rotate, and the transverse mixing blades can rotate synchronously. The longitudinal mixing blades and the transverse mixing blades can interact with each other, so that the food can flow quickly, so that the solutes in the food can collide quickly, and so that they can be quickly distributed in various positions of the food;

[0026] S3. During the reciprocating movement of the receiving component, when the receiving component approaches the adsorption magnetic plate on one side, a strong attraction will be generated between the adsorption magnetic plate and one end of the adsorption magnetic seat due to the difference in magnetic force between the two ends. At this time, the two adsorption magnetic seats can be driven to approach the adsorption magnetic plate at the same time. Otherwise, the two adsorption magnetic seats will approach the other adsorption magnetic plate.

[0027] S4. When the material receiving assembly reciprocates, the two adsorption magnetic seats will also reciprocate at the bottom of the material receiving assembly. When the adsorption magnetic seats move, they can scoop up a small amount of food solutes that have sunk to the bottom;

[0028] S5. During the use of the equipment, the ultraviolet light panel of the irradiation and sterilization component can continuously irradiate the food, which has a good sterilization effect on the food. When the receiving component moves back and forth, the irradiation and sterilization component can also move synchronously;

[0029] S6. During the movement, one end of the irradiation and sterilization component will come into contact with the touch-pressure plate, which can squeeze one end of the irradiation and sterilization component to cause an angular deflection of the one end of the irradiation and sterilization component, thereby changing the irradiation area of ​​the ultraviolet lamp board, and thus reciprocating to achieve stable, comprehensive and multi-angle sterilization treatment during food pretreatment. The pretreated food can be exported to the recycling box through the discharge port.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] In the present invention, a longitudinal mixing component and a transverse mixing component are provided in a matching manner. When pre-processing food, liquid food is added into a material receiving and processing box through a feeding pipe. At this time, the driving motor can be directly started to drive the reciprocating screw to rotate. The reciprocating screw can drive the material receiving component to move back and forth inside the processing box. At this time, the liquid food will continue to shake in the material receiving component. During this process, the top gear can mesh with the meshing rack and rotate. The first mounting shaft drives multiple longitudinal mixing blades to rotate, so as to stir and mix the food well. At the same time, the meshing worm can also drive the second mounting shaft with a meshing worm gear to rotate, and the transverse mixing blades can rotate synchronously. The longitudinal mixing blades and the transverse mixing blades can interact with each other, so that the food can flow quickly, so that the solutes in the food can collide quickly, and are quickly distributed in various positions of the food. Through this design, the food can be pre-processed quickly, and at the same time, the comprehensiveness and effectiveness of the food pre-processing can be guaranteed, the solutes can be effectively prevented from sinking to the bottom, and the solutes can be evenly distributed in the food, so as to ensure the accuracy of subsequent sample detection.

[0032] In the present invention, two adsorption magnetic seats are arranged in the material receiving component, and two adsorption magnetic plates with different magnetic poles are arranged on the inner walls on both sides of the device. During the reciprocating movement of the material receiving component, when the material receiving component is close to the adsorption magnetic plate on one side, due to the different magnetic forces between the adsorption magnetic plate and one end of the adsorption magnetic seat, a strong attraction will be generated between the two. At this time, the two adsorption magnetic seats can be driven to approach the adsorption magnetic plate at the same time, and vice versa, the two adsorption magnetic seats will approach the other adsorption magnetic plate. Therefore, when the material receiving component reciprocates, the two adsorption magnetic seats will also reciprocate at the bottom of the material receiving component. When the adsorption magnetic seats move, some small amounts of food solutes that have sunk to the bottom can be scooped up again. Through this design, the magnetic attraction effect can be utilized to realize the scooping processing of the solutes that have sunk to the bottom while the material receiving component reciprocates. When used in conjunction with the longitudinal mixing component and the transverse mixing component, the pretreatment effect of the food can be further improved.

[0033] In the present invention, two deflectable irradiation and sterilization components are provided in a matching manner. During the use of the equipment, the ultraviolet lamp board of the irradiation and sterilization component can continuously irradiate the food, thereby having a good sterilization effect on the food. While the material receiving component is moving back and forth, the irradiation and sterilization component can also move synchronously. During the movement, one end of the irradiation and sterilization component will come into contact with the touch plate, and the touch plate can squeeze one end of the irradiation and sterilization component to cause an angular deflection of the one end of the irradiation and sterilization component, thereby changing the irradiation area of ​​the ultraviolet lamp board. In this way, stable, comprehensive and multi-angle sterilization treatment can be achieved during the food pretreatment process, thereby ensuring the accuracy of subsequent food inspections.

The material receiving assembly 9 is used to detect the stable material receiving of food, and the longitudinal mixing assembly 7 and the transverse mixing assembly 12 are used for all-round mixing processing of food.

[0048] The material receiving assembly 9 includes a material receiving and processing box 91, the reciprocating screw 10 is threadedly connected to the threaded hole arranged inside the material receiving and processing box 91, a feed pipe 92 and a discharge port 93 are fixedly installed on the outer wall of one side of the material receiving and processing box 91, the feed pipe 92 is located above the discharge port 93, and two side stroke grooves 5 are arranged on the outer wall of one side of the top box 2, the feed pipe 92 and the discharge port 93 respectively pass through the side stroke grooves 5 and extend to the outside of the processing box 3, and a mounting top plate 94 is fixedly installed at the top center position of the material receiving and processing box 91.

[0049] A rotating hole is provided inside the mounting top plate 94, and the longitudinal mixing assembly 7 is rotatably installed in the rotating hole. The longitudinal mixing assembly 7 includes a first mounting shaft 72, and a limiting rotating rib 73 and a plurality of longitudinal mixing blades 74 are fixedly installed outside the first mounting shaft 72. The limiting rotating rib 73 is rotatably connected to a rotating groove provided on the inner side of the rotating hole. A top gear 71 is fixedly installed on the top of the first mounting shaft 72, and a meshing worm 75 is fixedly installed on the bottom end of the first mounting shaft 72. A meshing rack 11 is laterally fixedly installed inside the top box 2, and the top gear 71 and the meshing rack 11 are meshedly connected with each other.

[0050] The transverse mixing assembly 12 includes a second mounting shaft 122 , a meshing worm gear 123 is fixedly mounted at the middle position of the second mounting shaft 122 , a transverse mixing blade 121 is fixedly mounted on the outer surface of the second mounting shaft 122 , and the meshing worm 75 and the meshing worm gear 123 are meshedly connected with each other.

[0051] The specific implementation method is as follows: when pre-processing food, liquid food is added into the material receiving and processing box 91 through the feed pipe 92. At this time, the drive motor 6 can be directly started to drive the reciprocating screw 10 to rotate. The reciprocating screw 10 can drive the material receiving component 9 to move back and forth inside the processing box 3. At this time, the liquid food will continue to shake in the material receiving component 9. During this process, the top gear 71 can mesh and rotate with the meshing rack 11, and the first mounting shaft 72 drives multiple longitudinal mixing blades 74 to rotate, so as to stir and mix the food well. At the same time, the meshing worm 75 can also drive the second mounting shaft 122 with the meshing worm gear 123 to rotate, and the transverse mixing blades 121 can rotate synchronously. The longitudinal mixing blades 74 and the transverse mixing blades 121 can interact with each other, so that the food can flow quickly, the solutes in the food can collide quickly, and they can be quickly distributed in various positions of the food.

[0052] Through this design, food can be pretreated quickly, and at the same time, the comprehensiveness and effectiveness of food pretreatment can be guaranteed, solutes can be effectively prevented from settling to the bottom, so that solutes can be evenly distributed in the food, thereby ensuring the accuracy of subsequent sample testing.

[0053] A guide rail is fixedly installed on the inner wall of the bottom surface of the material receiving and processing box 91, and two adsorption magnetic seats 14 with slide grooves are slidably installed on the guide rail. The magnetic poles of one end of the two adsorption magnetic seats 14 are different. Adsorption magnetic plates 13 are fixedly installed on the inner walls of both sides of the processing box 3, and the other end of the adsorption magnetic seat 14 is different from the magnetic pole of the adsorption magnetic plate 13.

[0054] The specific implementation method is as follows: during the reciprocating movement of the material receiving component 9, when the material receiving component 9 is close to the adsorption magnetic plate 13 on one side, due to the different magnetic forces between the adsorption magnetic plate 13 and one end of the adsorption magnetic seat 14, a strong attraction will be generated between the two. At this time, the two adsorption magnetic seats 14 can be driven to approach the adsorption magnetic plate 13 at the same time, and vice versa, the two adsorption magnetic seats 14 will approach the other adsorption magnetic plate 13. Therefore, when the material receiving component 9 reciprocates, the two adsorption magnetic seats 14 will also reciprocate at the bottom of the material receiving component 9. When the adsorption magnetic seat 14 moves, it can shovel up a small amount of food solutes that have sunk to the bottom.

[0055] Through this design, by utilizing the magnetic effect, the solutes that have settled on the bottom can be scooped up while the material collecting component 9 reciprocates. When used in conjunction with the longitudinal mixing component 7 and the transverse mixing component 12, the pretreatment effect of food can be further improved.

[0056] Two irradiation and sterilization components 8 are arranged on the top of the material receiving and processing box 91. The irradiation and sterilization components 8 are used to detect the synchronous sterilization treatment of food processing. The irradiation and sterilization components 8 include two mounting top plates 84. The two mounting top plates 84 are fixedly mounted on the top surface of the material receiving and processing box 91. A lamp holder shaft 85 is rotatably mounted between the two mounting top plates 84. Both ends of the lamp holder shaft 85 are fixedly mounted with a set torsion spring 83. One end of the set torsion spring 83 is fixedly connected to the outer wall of one side of the mounting top plate 84. A sterilization lamp holder 82 is fixedly mounted on the outside of the lamp holder shaft 85. An ultraviolet lamp board 81 is fixedly mounted on the outer wall of one side of the sterilization lamp holder 82. Touch pressure plates 15 are fixedly mounted on the inner walls of both sides of the top box 2. The touch pressure plate 15 is located on one side of the ultraviolet lamp board 81.

[0057] The specific implementation method is as follows: during the use of the equipment, the ultraviolet lamp board 81 of the irradiation and sterilization component 8 can continuously irradiate the food, thereby having a good sterilization effect on the food. While the material receiving component 9 is moving back and forth, the irradiation and sterilization component 8 can also move synchronously. During the movement, one end of the irradiation and sterilization component 8 will come into contact with the touch plate 15. The touch plate 15 can squeeze one end of the irradiation and sterilization component 8, causing the one end of the irradiation and sterilization component 8 to produce an angular deflection, thereby changing the irradiation area of ​​the ultraviolet lamp board 81. In this way, stable, comprehensive and multi-angle sterilization treatment can be achieved during the food pretreatment process, thereby ensuring the accuracy of subsequent food testing.

[0058] The present invention also discloses a sample pretreatment process for food testing, comprising the following steps:

[0059] S1. When pre-processing food, add liquid food into the material receiving and processing box 91 through the feeding pipe 92. At this time, the driving motor 6 can be directly started to drive the reciprocating screw 10 to rotate. The reciprocating screw 10 can drive the material receiving assembly 9 to reciprocate inside the processing box 3. At this time, the liquid food will continue to shake in the material receiving assembly 9;

[0060] S2. During this process, the top gear 71 can mesh with the meshing rack 11 to rotate, and the first mounting shaft 72 drives the plurality of longitudinal mixing blades 74 to rotate, so as to stir and mix the food well. Meanwhile, the meshing worm 75 can also drive the second mounting shaft 122 with the meshing worm gear 123 to rotate, and the transverse mixing blades 121 can rotate synchronously. The longitudinal mixing blades 74 and the transverse mixing blades 121 can interact with each other, so that the food can flow quickly, so that the solutes in the food can collide quickly, and so that they can be quickly distributed in various positions of the food.

[0061] S3. During the reciprocating movement of the material receiving component 9, when the material receiving component 9 approaches the adsorption magnetic plate 13 on one side, since the magnetic forces of the adsorption magnetic plate 13 and one end of the adsorption magnetic seat 14 are different, a strong attraction will be generated between the two. At this time, the two adsorption magnetic seats 14 can be driven to approach the adsorption magnetic plate 13 at the same time, otherwise, the two adsorption magnetic seats 14 will approach the other adsorption magnetic plate 13;

[0062] S4. When the material receiving assembly 9 reciprocates, the two adsorption magnetic seats 14 also reciprocate at the bottom of the material receiving assembly 9. When the adsorption magnetic seats 14 move, they can scoop up a small amount of food solutes that have sunk to the bottom;

[0063] S5. During the use of the device, the ultraviolet lamp board 81 of the irradiation and sterilization component 8 can continuously irradiate the food, which has a good sterilization effect on the food. When the receiving component 9 moves back and forth, the irradiation and sterilization component 8 can also move synchronously;

[0064] S6. During the movement, one end of the irradiation and sterilization component 8 will come into contact with the touch-pressure plate 15. The touch-pressure plate 15 can squeeze one end of the irradiation and sterilization component 8, causing the one end of the irradiation and sterilization component 8 to produce an angular deflection, thereby changing the irradiation area of ​​the ultraviolet lamp board 81. In this way, stable, comprehensive and multi-angle sterilization treatment is achieved during the food pretreatment process. The pretreated food can be exported to the recycling box 4 through the discharge port 93.

[0065] Working principle: When pre-processing food, liquid food is added into the material receiving and processing box 91 through the feed pipe 92. At this time, the drive motor 6 can be directly started to drive the reciprocating screw 10 to rotate. The reciprocating screw 10 can drive the material receiving assembly 9 to move back and forth inside the processing box 3. At this time, the liquid food will continue to shake in the material receiving assembly 9; during this process, the top gear 71 can mesh and rotate with the meshing rack 11, and the first installation shaft 72 drives the multiple longitudinal mixing blades 74 to rotate, so as to stir and mix the food well. At the same time, the meshing worm 75 can also drive the second installation shaft 122 with the meshing worm gear 123 to rotate, and the transverse mixing blades 121 can rotate synchronously. The longitudinal mixing blades 74 and the transverse mixing blades 121 can interact with each other, so that the food can flow quickly, so that the solutes in the food can collide quickly, and they can be quickly distributed in various positions of the food;

[0066] During the reciprocating movement of the receiving component 9, when the receiving component 9 approaches the adsorption magnetic plate 13 on one side, since the magnetic forces of the adsorption magnetic plate 13 and one end of the adsorption magnetic seat 14 are different, a strong attraction will be generated between the two. At this time, the two adsorption magnetic seats 14 can be driven to approach the adsorption magnetic plate 13 at the same time, and vice versa, the two adsorption magnetic seats 14 will approach the other adsorption magnetic plate 13; when the receiving component 9 reciprocates, the two adsorption magnetic seats 14 will also reciprocate at the bottom of the receiving component 9. When the adsorption magnetic seats 14 move, some small amounts of food solutes that have sunk to the bottom can be shoveled up again;

[0067] During the use of the equipment, the ultraviolet lamp board 81 of the irradiation and sterilization component 8 can continuously irradiate the food, which has a good sterilization effect on the food. When the material receiving component 9 moves back and forth, the irradiation and sterilization component 8 can also move synchronously. During the movement, one end of the irradiation and sterilization component 8 will come into contact with the touch plate 15, and the touch plate 15 can squeeze one end of the irradiation and sterilization component 8, causing the one end of the irradiation and sterilization component 8 to produce an angular deflection, thereby changing the irradiation area of ​​the ultraviolet lamp board 81. In this way, stable, comprehensive and multi-angle sterilization treatment can be achieved during the food pretreatment process. The pretreated food can be discharged into the recycling box 4 through the discharge port 93.

[0068] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.

During the reciprocating movement of the material receiving component (9), when the material receiving component (9) approaches the adsorption magnetic plate (13) on one side, since the magnetic forces of the adsorption magnetic plate (13) and one end of the adsorption magnetic seat (14) are different, a strong attraction will be generated between the two. At this time, the two adsorption magnetic seats (14) can be driven to approach the adsorption magnetic plate (13) at the same time.
