Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food additive testing device. Background Technology

[0002] Food safety has always been a major problem affecting people's daily lives. With the development of the times, in order to ensure the taste of food, many manufacturers choose to add a certain amount of food additives to food. However, if the additives are added in excess, they may harm people's health. Therefore, it is necessary to test the content of additives in food.

[0003] For example, Chinese utility model patent (CN217060166U) discloses a detection device for food additives, which describes: "The food can be pulverized and fully mixed with water by a motor driving a stirring rod and pulverizing blades, so that the additives dissolve in the water. Then the cover can be lifted and removed from the pulverizing tank. During the lifting process, the filter screen will rise together, directly filtering and carrying away the pulverized residue in the mixture, avoiding the removal of pulverized residue during sampling, which would affect the test results."

[0004] In summary, the existing technology has the following problems: some existing food additive testing equipment is too time-consuming and labor-intensive when filtering and crushing residues, and is inefficient. Therefore, this application proposes a testing equipment for food additives. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a food additive detection device that allows for residue removal through disassembly, thus saving time and effort and improving efficiency.

[0006] The food additive testing device proposed in this utility model includes a mixing tank, a connecting pipe fixed at the bottom center of the mixing tank, a filter tank fixed at the bottom center of the connecting pipe, a support rod fixed in the middle of the interior of the filter tank, a filter plate located inside the filter tank sleeved on the outer surface of the support rod, a slot opened at one end of the filter tank, a fixing ring fixed at one end of the filter plate, a locking plate rotatably connected to the outer surface of the fixing ring and embedded in the slot, and a rotating handle fixed at the end of the fixing ring away from the filter plate.

[0007] Preferably, a bolt is inserted through the surface of the rotating handle and threadedly connected thereto, and threaded holes that mate with the bolt are opened at both ends of the surface of the filter can.

[0008] Preferably, the filter can has a pair of limiting blocks at both the left and right ends of its surface for limiting the rotation handle.

[0009] Preferably, a motor is fixed at the top center of the mixing tank, and a rotating shaft located inside the mixing tank is fixed at the rotating end of the motor, with a blade fixed on the outer surface of the rotating shaft.

[0010] Preferably, a feed chute is provided through the top of the mixing tank.

[0011] Preferably, a solenoid valve is installed inside the connecting pipe, and a discharge pipe is fixed at the bottom of the filter tank.

[0012] Preferably, the outer surface of the mixing tank is fixed with support legs, and each of the four corners of the filter tank is fixed with a connecting rod between the support legs and the support legs.

[0013] Preferably, the inner wall of the slot and the outer surface of the card plate are both fixed with rubber pads.

[0014] The beneficial effects of this utility model are: the filter plate can be rotated 180° and fixed, and combined with the reverse flushing water flow, the filter plate does not need to be completely disassembled. Cleaning can be completed with only partial operation, which saves time and effort and improves efficiency; the filter plate adopts a quick-release structure with the fixing ring, clamping plate, clamping groove and support rod, which supports the replacement of filter plates with different pore sizes and adapts to a variety of testing needs.

[0022] Reference Figure 1-6 A food additive testing device includes a mixing tank 1, a connecting pipe 2 fixed at the bottom center of the mixing tank 1, a filter tank 3 fixed at the bottom center of the connecting pipe 2, a support rod 4 fixed in the middle of the interior of the filter tank 3, a filter plate 5 located inside the filter tank 3 fitted on the outer surface of the support rod 4, a slot 6 opened at one end of the filter tank 3, a fixing ring 7 fixed at one end of the filter plate 5, a locking plate 8 rotatably connected to the outer surface of the fixing ring 7 and embedded in the slot 6, a rotating handle 9 fixed at the end of the fixing ring 7 away from the filter plate 5, a bolt 10 threadedly inserted through the surface of the rotating handle 9, and threaded holes 11 that cooperate with the bolts 10 opened at both the left and right ends of the surface of the filter tank 3.

[0023] The mixture of food and water in mixing tank 1 is introduced into filter tank 3 through connecting pipe 2. The horizontally arranged filter plate 5 can filter food residue from the water containing additives. When it is necessary to clean the residue, the screw 10 can be rotated to remove it from the threaded hole 11. Then, the rotating handle 9 is rotated, which drives the fixing ring 7 and the filter plate 5 to rotate 180° around the support rod 4. The screw 10 is then inserted into the threaded hole 11 on the other side to fix the filter plate 5. By injecting water into the feed trough 16, the food residue on the surface of the blade 15 and the filter plate 5 can be backwashed, thereby quickly cleaning the connecting pipe 2 and the filter tank 3.

[0024] The rotatable bolt 10 removes it from the threaded hole 11. By pulling the rotating handle 9, the fixing ring 7, filter plate 5 and clamping plate 8 are moved away from the filter tank 3, thereby quickly replacing the filter plate 5 with different pore sizes to meet the testing needs of different food samples. For example, a large pore size filter plate is used when testing liquid food, and a small pore size filter plate is used for solid residues. This design significantly reduces downtime for maintenance.

[0025] A pair of limiting blocks 12 are fixed at both ends of the surface of the filter tank 3 to limit the rotation handle 9, thereby fixing the position of the rotation handle 9 and ensuring the stability of the filter plate 5.

[0026] A motor 13 is fixed at the top center of the mixing tank 1. A rotating shaft 14 located inside the mixing tank 1 is fixed to the rotating end of the motor 13. A blade 15 is fixed to the outer surface of the rotating shaft 14. When the motor 13 is started, the motor 13 drives the blade 15 to rotate at high speed through the rotating shaft 14. The blade 15 is made of stainless steel and has a corrosion-resistant coating on its surface, which can quickly crush food samples into fine particles.

[0027] The top of the mixing tank 1 is provided with a feed trough 16. The operator adds the food sample to be tested and an appropriate amount of solvent into the mixing tank 1 through the feed trough 16. At the same time, a sealing cover can be installed on the top to avoid external contamination.

[0028] The connecting pipe 2 is equipped with a solenoid valve 17, which can control the communication between the mixing tank 1 and the filter tank 3. The bottom of the filter tank 3 is fixed with a discharge pipe 18.

[0029] The outer surface of the mixing tank 1 is fixed with support legs 19, and the four corners of the filter tank 3 are all fixed with connecting rods 20 between the support legs 19 and the support legs 19.

[0030] Rubber pads are fixed to the inner wall of the slot 6 and the outer surface of the card plate 8. The rubber pads can enhance the sealing and prevent liquid leakage, while using their friction to enhance the stability of the card plate 8.

[0031] When using this device, open the sealing cover of the feed trough 16 and put the food sample to be tested and an appropriate amount of solvent into the mixing tank 1. Start the motor 13 to drive the blade 15 to rotate at high speed, which can quickly crush the food sample into fine particles, allowing it to mix thoroughly with the solvent to form a suspension. After mixing, open the solenoid valve 17 in the connecting pipe 2, and the mixture flows into the filter tank 3 through the connecting pipe 2. After entering the filter tank 3, the mixture flows through the horizontally set filter plate 5, which can trap food residue. The water containing the additives can be easily collected through the discharge pipe 18 for testing. Rotate the bolt 10 to remove it from the threaded hole 11, releasing the filter plate 5 from its fixation. Rotate the handle 9 to rotate the fixing ring 7 and the filter plate 5 180° around the support rod 4. Reinsert the bolt 10 into the corresponding threaded hole 11 to fix the filter plate 5. Inject clean water from the feed trough, and the water flow back to flush the filter plate 5 and the blade 15. The residue is discharged from the discharge pipe 18 with the water flow. This design avoids the tedious traditional disassembly and cleaning. When the filter plate 5 needs to be replaced, rotate the bolt 10 to remove it from the threaded hole 11, pull the rotating handle 9 outward to drive the clamping plate 8 and the filter plate 5 out of the filter tank 3, and replace the filter plate 5 with a different pore size as needed.
