Description

Technical Field

[0001] This invention belongs to the field of sampling and testing technology, specifically relating to a sampling device for testing soybean products. Background Technology

[0002] Food safety is of paramount importance at present. Soy products need to be sterilized during the production process to extend their shelf life. This requires sampling and testing of soy products for microbial content before they leave the factory. The current sampling and testing method involves placing soy products and physiological saline in a homogenization bag in a certain ratio and manually tapping it to obtain a sampling solution. The sampling solution is then diluted to obtain a test solution for testing.

[0003] However, for factories with large production needs, manually beating the soy products and placing them in homogenization bags in proportion will increase factory costs and the workload of staff. Furthermore, different beating strengths can lead to uneven mixing of soy products and saline solution. During the process of preparing the sample solution from the dilution solution, microorganisms may enter the sample solution. Finally, the test data may contain more errors, which may affect the quality of the finished product and the health of consumers. Summary of the Invention

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Existing sampling of soybean products is done manually. However, the present invention sets up a moving device, a homogenizing device, a beating device, a sterilization device and a saline feeding device in the sampling box to realize the integrated sampling of soybean product testing. It eliminates the need for manual step-by-step operation, reduces labor intensity and avoids the risk of contamination and operation error caused by manual operation. (2) A combination of 75% food-grade ethanol atomization spray and high-temperature ozone deep sterilization is adopted. The alcohol spray achieves full coverage atomization inside the sampling box through spray pipe three and spray pipe four. The ozone diffuses through the sampling box cavity, the tapping box cavity, and various fluid pipes. This not only completes the sterilization of the surface of the internal cavity of the equipment, but also performs aseptic pretreatment on the fluid channels such as pipe one, sampling pipe, and spray pipe one, thus avoiding the sample from being contaminated during the sampling process and ensuring the accuracy of the test. (3) All seals are made of 2-3 layers of food-grade fluororubber or high-temperature resistant silicone lip seals, and are interference fit with the contact surface, which effectively prevents external contaminants from seeping in or leakage of the internal sterile environment, fully complies with the safety standards for food testing, and avoids secondary contamination of the samples by the materials of the equipment itself. (4) The cylinder drives the sliding parts to reciprocate, driving the first and second rotating shafts to rotate synchronously, so that the hammer repeatedly hits the pressing plate; combined with the compression and rebound of the strong spring, the pressing plate presses down and rebounds the bean products in the homogenization box. Combined with the pre-wetting and dilution of physiological saline, the bean products are fully mixed with physiological saline, effectively avoiding local clumping, forming a sample solution with excellent uniformity, and reducing the systematic error of the test results. (5) The slapping device makes the slapping hammer move smoothly and be evenly stressed through the coordinated transmission of rotating shaft one, rotating shaft two, connecting part one, cam, connecting rod one and connecting rod two; (6) The pressure sensor can monitor the weight of the bean products in the homogenizing chamber. Combined with the total flow meter and the split flow meter to control the amount of saline injected, the dilution ratio can be adjusted as needed to meet the sample concentration requirements of different detection items.

[0053] The working principle of this invention is as follows: After the equipment is started, pump two is activated first, and 75% food-grade ethanol in the alcohol storage tank is transported through spray pipe two 13 to spray pipe one 12, spray pipe three 27 and spray pipe four 28. The sampling box 1 is fully covered by atomized spraying from spray head two and spray head three to achieve surface sterilization. After a period of time, pump two is turned off and the ozone system is turned on. High-temperature ozone is delivered to ozone flat pipe 15 through ozone inlet pipe 19. The controller opens valve one, valve two 18 and valve three 16, so that ozone diffuses through three branches. The first branch, ozone branch pipe one, connects to the inside of sampling box 1. The second branch, ozone pipe four 31, connects to the inside of tapping box 29 to achieve deep sterilization of the cavity. The third branch, ozone pipe two 14 connects to pipe one 5, ozone pipe three 17 connects to spray pipe two 13, and ozone pipe one 11 connects to sampling pipe 10 to achieve aseptic pretreatment of each fluid pipe. After a period of time, the ozone system is turned off.

[0054] An external aseptic crushing device performs aseptic crushing on the formed soybean products. The crushed soybean products are temporarily stored above the feeding device. Cylinder 23 is activated, causing the baffle 22 to disengage from the feeding cone 21, allowing the crushed soybean products to fall into the homogenizing tank 26 below. After a period of settling, the pressure sensor transmits the weight of the soybean products entering the homogenizing tank 26 to the controller. Based on the sampling and dilution ratio, extraction pump 6 is activated, transferring the saline solution from the saline storage tank 4 to multiple pipes 7 via pipe 5. This saline solution is then injected into the homogenizing tank 26 below the feeding cone 21, achieving preliminary wetting and dilution pretreatment of the raw materials. The flow meter on pipe 7 is used to measure the saline solution according to the sampling... The sample dilution ratio is adjusted so that a set amount of physiological saline enters the homogenization tank 26. Pump 6 is turned off, and servo motor 2 is turned on. Servo motor 2 drives the ball screw to rotate, causing slider 25 to slide along guide rail 30 to below cylinder 20. Servo motor 2 is turned off, and cylinder 20 is turned on. Cylinder 20 pushes connecting plate 35 downwards until the protrusion 1 of pressing plate 36 mates with the groove 1, and connecting base 33 contacts adsorption element 2. Cylinder 20 is turned off, and adsorption element 2 is turned on. Adsorption element 2 adsorbs connecting base 33. Adsorption element 1 is turned off (adsorption element 1 adsorbs the column connecting plate 35 before the equipment is turned on). Cylinder 20 is turned on, and cylinder 20 returns to its initial position. Servo motor 2 causes the homogenizing box 26 to move the pressing plate 36 to the specified position. Servo motor 2 is then turned off, and cylinder 3 48 is activated. Cylinder 3 48 drives the sliding member 47 to reciprocate along the sliding through hole of the tapping box 29. The sliding member 47, through connecting rod 1 44 and connecting rod 2 46, drives rotating shaft 1 39 and rotating shaft 2 to rotate synchronously. This causes the tapping hammer 37 at the end of connecting rod 38 to tap the pressing plate 36 inside the homogenizing box 26, pressing the pressing plate 36 downwards. The strong spring is compressed, and during the downward pressing of the pressing plate 36, the soybean products and saline solution inside the homogenizing box 26 are mixed. After the pressing plate 36 is pressed down, the corresponding tapping hammer 37 disengages from the pressing plate 36 under the drive of cylinder 3 48. A strong spring drives the pressing plate 36 to move upward. At this time, the height of the pressing plate 36 is lower than the bottom of the sliding groove of the homogenizing box 26. After a period of reciprocating motion, during the process of the pressing plate 36 pressing down and rebounding, sample liquid is obtained in the homogenizing box 26. The cylinder 3 48 is closed, and the extraction pump 3 9 is turned on to extract the sample liquid in the homogenizing box 26 into the sample liquid storage box 8 through the sampling pipe 10. The extraction pump 3 9 is turned off, and the servo motor 2 is turned on to move the homogenizing box 26 and the pressing plate 36 to the initial position of the homogenizing box. The staff removes the baffle door 3, cleans the bean products and pressing plate 36 in the homogenizing box 26, replaces the filter screen, resets it after cleaning, and then restores the baffle door 3.

[0055] In this invention, the entire assembly connected to the pressing plate 36 returns to its initial position in use, i.e., the adsorption element adsorbs and holds the connecting plate 35.

[0056] In this invention, the above process can be automatically controlled by a controller.

[0057] In this invention, the above process can be adjusted according to the on-site conditions.
