Description

Technical Field

[0001] The present invention relates to the technical field of food detection, in particular to a self-cleaning food additive detection device. Background Art

[0002] In order to achieve a longer shelf life and better taste, food often needs to be added with some additives (such as flavorings and preservatives, etc.). However, there are strict controls on the type and amount of additives added. Testing equipment can detect the type and content of additives in food.

[0003] When testing food, it is necessary to use a solvent to dissolve the food, and then the dissolved solution is tested to obtain the additive content. The tank that dissolves the additives needs to be rinsed and cleaned after use to avoid affecting the subsequent testing structure.

[0004] To address the aforementioned issues, a Chinese patent application, CN116558924A, discloses a sample pretreatment device for food testing. The device comprises a support assembly comprising a base, a rotating platform, and a lifting mechanism. The lifting mechanism comprises a lifting rod vertically mounted on the rotating platform, a first extension rod, and a second extension rod. A flushing assembly comprises a flushing barrel and a flushing nozzle. A crushing assembly comprises a crushing blade and a first motor. A sampling assembly is mounted on the second extension rod. The support, crushing, and sampling assemblies work together to achieve automatic sample crushing and sampling, enhancing the automation of sample pretreatment. The sample cup and crushing blade are mounted separately. Driven by the lifting mechanism and rotating platform, the crushing blade can enter the sample cup to crush the sample and also enter the flushing barrel for rinsing and cleaning. After sampling, the sample cup can be removed for cleaning. Its light weight makes cleaning easier and eliminates the risk of water intrusion into the motor, making it safer.

[0005] For example, in the prior art, Chinese patent publication number CN113020170A discloses a food additive content detector that is easy to clean. By setting a cylinder, a ferrule and a reset spring, the cleaning liquid then enters the water spray pipe and flows upward and flushes the inner wall of the test tube. This method can keep the inner wall of the test tube flushed when it is stored, so that the inner wall is cleaner under the flushing of the cleaning liquid. At the same time, after the flushing is completed, it can be directly stored in a tightly fitted state in the annular groove with good sealing, keeping the interior clean while facilitating long-term storage, and the inner wall of the test tube will not be contaminated during storage after cleaning.

[0006] Combined with the above materials, it can be seen that the existing technology can achieve the purpose of cleaning the device by spraying pressurized water through the nozzle, but in actual use, the position of the nozzle in the existing technology is generally fixed, so only one position can be flushed during flushing, and other positions are cleaned with flowing water. The cleaning effect of this method is limited. Summary of the Invention

[0007] The object of the present invention is to provide a self-cleaning food additive detection device for food, so as to solve the problem of limited cleaning effect of the device proposed in the above background technology.

The crushing box and the sealing cover are connected to each other, and a pair of roller-type crushing rollers are rotatably installed inside the crushing box.

[0010] A longitudinally arranged central rotating shaft is rotatably mounted in the middle of the mixing tank, and a stirring rod is fixedly mounted on the upper end of the central rotating shaft. A spectrophotometer for detecting the composition of the dissolved solution is fixedly mounted on the front side of the upper surface of the support base.

[0011] A heating pipe with a spiral structure is fixedly installed on the inner wall of the mixing tank, and a circulation mechanism for circulating air inside the heating pipe is fixedly installed on the upper surface of the support base;

[0012] A water storage tank is fixedly installed on the lower surface of the interior of the mixing tank, and a flushing nozzle connected to the water storage tank is rotatably installed on the upper surface of the water storage tank, and a swing mechanism is provided between the flushing nozzles to drive the flushing nozzles to rotate back and forth.

[0013] Preferably, the mixing tank is communicated with the spectrophotometer via a delivery pipe fixedly installed on the side thereof, and a delivery pump is provided in the middle of the delivery pipe.

[0014] Preferably, the circulation mechanism includes a heating box fixedly mounted on the upper surface of the support base, the heating pipe is connected to the upper end of the heating box, and an electric control valve is fixedly mounted on the bottom end of the heating pipe.

[0015] Preferably, a transversely arranged piston plate is slidably installed inside the heating box, and a lifting screw is threadedly installed inside the piston plate, and the lifting screw rotates synchronously with the central rotating shaft through the transmission belt at its bottom, and the piston plate is always located below the bottom end of the heating pipe.

[0016] Preferably, an electric heater for heating the air is fixedly installed at the upper end of the interior of the heating box, and a storage box for storing solid cleaning materials is fixedly installed at the lower end of the interior of the heating box.

[0017] Preferably, the heating box is connected to the water tank through a connecting pipe fixedly installed on its side, and four water tanks are evenly arranged at equal angles.

[0018] Preferably, all the water storage tanks are connected to each other via connecting pipes.

[0019] Preferably, the swing mechanism includes a connecting rod rotatably mounted on the side of the flushing nozzle, and the flushing nozzle is configured as an electric pressurized nozzle.

[0020] Preferably, a first magnetic block is fixedly mounted on the front end of the connecting rod for driving the connecting rod to move, and the first magnetic block and the second magnetic block magnetically repel each other, and the second magnetic block is fixedly mounted on the outer surface of the central shaft.

[0021] Preferably, the first magnetic block and the second magnetic block have the same height, and a return spring is fixedly installed on the inner side wall of the water tank, and the return spring is fixedly connected to the flushing nozzle.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-cleaning food additive detection equipment adopts a new structural design, the specific contents of which are as follows:

[0023] 1. Use the crushing roller in the crushing box to crush the food to be tested. The crushed food falls into the mixing tank and is dissolved by the solvent. The dissolved solution is transported to the spectrophotometer through the delivery pump. The spectrophotometer is used to determine the solution composition by detecting the spectrum in the solution, thereby achieving the purpose of detecting additives in food;

[0024] Furthermore, during the process of the solvent dissolving the food, the stirring rod rotates, and the transmission screw connected to the stirring rod drives the lifting screw to rotate. During the rotation process, the lifting screw drives the piston plate installed with a thread passing through its outside to move up and down, thereby blowing the air in the heating box into the heating pipe (the air in the heating box is heated by an electric heater), and the hot air flowing in the heating pipe is used to heat the solution in the mixing tank, thereby accelerating the dissolution rate.

[0025] 2. After the device is used, open the flushing nozzle and use it to spray the clean water in the water tank (clean water is pre-filled into the water tank). Under the pressurized action of the flushing nozzle, use the sprayed water flow to flush the inside of the mixing tank to achieve the purpose of self-cleaning;

[0026] Furthermore, when the food is dissolved, the central shaft rotates, causing the piston plate in the heating box to keep moving up and down. The upward movement of the piston plate creates negative pressure at the lower end of the interior of the heating box. As a result, clean water in the water storage tank is sucked into the heating box through the connecting pipe under the action of the negative pressure. The sucked clean water contacts the storage box inside the heating box, thereby dissolving the solid cleaning material in the storage box, and utilizing the cleaning material to improve the cleaning effect of the clean water.

[0027] Furthermore, the central shaft keeps rotating during cleaning, and the rotation of the central shaft drives the second magnetic block on its outer surface to rotate. When the second magnetic block rotates to the position corresponding to the first magnetic block, the magnetic adsorption effect is used to drive the connecting rod to move, and the connecting rod is used to drive the flushing nozzle to rotate. Then, under the elastic pulling action of the reset spring, the flushing nozzle swings back and forth, thereby expanding the overall flushing range and achieving better cleaning effect.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 3 In order to detect the additive components in food by spectral detection, this embodiment provides the following technical solutions, which specifically disclose: a support base 1 placed horizontally on the ground, a longitudinally arranged mounting side plate 2 is fixedly installed on the rear side of the upper surface of the support base 1, and a mixing tank 3 is fixedly installed in the middle position of the upper surface of the support base 1, a water injection pipe and a drainage pipe are fixedly passed through the side of the mixing tank 3, and a matching sealing cover 4 is arranged directly above the mixing tank 3, a driving screw 201 is rotatably installed on the front side of the mounting side plate 2 for driving the sealing cover 4 to move up and down, and a crushing box 5 is fixedly installed in the middle position of the upper surface of the sealing cover 4, the crushing box 5 and the sealing cover 4 are connected to each other, and a pair of roller-type crushing rollers 6 are rotatably installed inside the crushing box 5, a longitudinally arranged central rotating shaft 7 is rotatably installed in the middle position inside the mixing tank 3, and a stirring rod 8 is fixedly installed on the upper end of the central rotating shaft 7, and a spectrophotometer 10 for detecting the components of the dissolved solution is fixedly installed on the front side of the upper surface of the support base 1.

[0041] When using the device, first turn on the motor on the front side of the mounting side panel 2 to drive the driving screw 201 to rotate, and the rotation of the driving screw 201 drives the sealing cover 4 to move downward to the position matching the mixing tank 3, then put the food to be tested into the crushing box 5 from above, and the crushing roller 6 in the crushing box 5 rotates to crush the food, and the crushed food falls into the mixing tank 3, and then the solvent is injected into the mixing tank 3 through the water injection pipe. After the solvent reaches the specified amount, turn on the motor under the support base 1, and use the motor to drive the central shaft 7 to rotate, and drive the stirring rod 8 to rotate through the central shaft 7 to stir the inside of the mixing tank 3 and accelerate the dissolution of the food in the solvent. After the dissolution is completed, turn on the delivery pump 11, and at this time, the delivery pump 11 delivers the solution in the mixing tank 3 to the spectrophotometer 10 through the delivery pipe 9, and the spectrophotometer 10 is used to analyze the spectrum in the solution to determine the type and content of additives in the food.

[0042] Example 2: Please refer to Figure 4-Figure 6 In order to increase the dissolution rate of food by the solvent, this embodiment provides the following technical solutions, which specifically discloses that: a heating pipe 12 with a spiral structure is fixedly installed on the inner wall of the mixing tank 3, and a circulation mechanism for circulating air inside the heating pipe 12 is fixedly installed on the upper surface of the support base 1. The mixing tank 3 is connected to the spectrophotometer 10 through a delivery pipe 9 fixedly installed on its side, and a delivery pump 11 is provided in the middle of the delivery pipe 9. The circulation mechanism includes a heating box 13 fixedly installed on the upper surface of the support base 1, and the heating mechanism is fixedly installed on the upper surface of the support base 1. The heat pipe 12 is connected to the upper end of the heating box 13, and an electric control valve 14 is fixedly installed at the bottom end of the heating pipe 12. A horizontally arranged piston plate 15 is slidingly installed inside the heating box 13, and a lifting screw 16 is installed through a thread inside the piston plate 15. The lifting screw 16 rotates synchronously with the central rotating shaft 7 through the transmission belt 17 at its bottom. The piston plate 15 is always located below the bottom end of the heating pipe 12. An electric heater 18 for heating the air is fixedly installed at the upper end of the heating box 13, and a storage box 19 for storing solid cleaning materials is fixedly installed at the lower end of the heating box 13.

[0043] During the process of the solvent dissolving the food, the central rotating shaft 7 drives the lifting screw 16 to rotate through the transmission belt 17. During the rotation of the lifting screw 16, the piston plate 15 installed with a thread passing through the outside of the lifting screw 16 is driven to move up and down. By moving the piston plate 15, the air in the heating box 13 is blown into the heating pipe 12 (at this time, the electric control valve 14 at the bottom of the heating pipe 12 is closed, and the air can only flow in the heating pipe 12 and the heating box 13 and cannot be discharged). The air in the heating box 13 is heated by the electric heater 18, so that the heating pipe 12 is used to heat the solution in the mixing tank 3, thereby accelerating its dissolution speed of the food.

[0044] Example 3: Please refer to Figure 7-10In order to solve the problem that the nozzle position is fixed and the flushing effect is limited during cleaning of the traditional device, this embodiment provides the following technical solutions, which drive the flushing nozzle 23 to swing back and forth through a swinging mechanism, thereby expanding the flushing range and improving the cleaning effect. Specifically, a water tank 21 is fixedly installed on the lower surface of the mixing tank 3, and a flushing nozzle 23 connected to the water tank 21 is rotatably installed on the upper surface of the water tank 21, and a swinging mechanism is provided between the flushing nozzles 23 to drive the reciprocating rotation thereof. The heating box 13 is connected to the water tank 21 through a connecting pipe 20 fixedly installed on its side, and the water tank 21 is evenly provided with four equal angles. All water tanks 21 are connected to each other through connecting pipes 22. The swing mechanism includes a connecting rod 24 rotatably mounted on the side of the flushing nozzle 23, and the flushing nozzle 23 is configured as an electric pressurized nozzle. A first magnetic block 25 for driving the movement of the connecting rod 24 is fixedly mounted at the front end thereof, and the first magnetic block 25 and the second magnetic block 26 magnetically repel each other, and the second magnetic block 26 is fixedly mounted on the outer surface of the central rotating shaft 7. The first magnetic block 25 and the second magnetic block 26 have the same height, and a return spring 27 is fixedly mounted on the inner side wall of the water tank 21, and the return spring 27 is fixedly connected to the flushing nozzle 23.

[0045] After the device is used, the flushing nozzle 23 is turned on to spray the water in the water tank 21 through the flushing nozzle 23 to achieve the purpose of flushing and cleaning the inside of the mixing tank 3. In the early stage of dissolving the food, the piston plate 15 moves up and down. When the piston plate 15 moves upward, a negative pressure is generated at the lower end of the heating box 13. Under the action of the negative pressure, the water in the water tank 21 is sucked into the heating box 13 through the connecting pipe 20. The penetrated water contacts the storage box 19 in the heating box 13, thereby dissolving the solid cleaning material in the storage box 19, thereby improving its cleaning effect on the inside of the mixing tank 3. At the same time, the central shaft 7 keeps rotating, and the central shaft 7 rotates. During the process, the second magnetic block 26 outside it is driven to rotate. When the second magnetic block 26 rotates to the position corresponding to the first magnetic block 25, the magnetic repulsion between the first magnetic block 25 and the second magnetic block 26 is used to drive the connecting rod 24 to move, so that the connecting rod 24 drives the flushing nozzle 23 to rotate, and then cooperates with the elastic action of the reset spring 27 to reset the flushing nozzle 23, so that the flushing nozzle 23 swings back and forth, thereby expanding the overall flushing range and improving the cleaning effect. After flushing and cleaning are completed, the electric control valve 14 at the bottom end of the heating pipe 12 is opened. At this time, the hot air in the heating pipe 12 is ejected from the electric control valve 14, so as to achieve the purpose of drying the mixing tank 3.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
