Abstract
Description
Technical Field
[0001] This utility model relates to the field of dairy product testing technology, and in particular to a device for detecting starch adulteration in dairy products. Background Technology
[0002] Dairy products are of great importance in daily life, serving as a key source of nutrition. However, driven by economic interests, some unscrupulous merchants often adulterate dairy products with non-dairy ingredients such as starch to reduce costs and increase weight. This practice not only significantly reduces the nutritional value of dairy products but also poses a potential threat to consumer health. To protect consumer rights and maintain normal market order, effective equipment for detecting whether dairy products contain added starch is crucial. However, existing testing equipment has significant drawbacks. During testing, when dairy products are mixed with heated water, a milky white solidified substance forms on the inner wall of the mixing and dissolving storage tank. Simultaneously, the starch in the dairy products, upon heating, coagulates into flocculent precipitates within the storage tank, adhering tightly to the tank wall. If these residual substances are not cleaned in time, they will gradually accumulate and thicken, severely interfering with the normal conduct of subsequent testing. Utility Model Content
[0003] The main purpose of this invention is to provide a detection device for starch adulteration in dairy products, which can effectively solve the problems in the background art.

Two short nozzles 135 are fixedly connected to the lower part of the outer surface of both short pipes 133. Long nozzles 136 are fixedly connected to the lower left and lower right ends of the annular pipe 134. The two long nozzles 136 and the four short nozzles 135 are located in the upper part of the inner side of the annular frame 74 and do not contact the annular frame 74. The lower part of the feed pipe 61 is located in the middle of the annular pipe 134 and does not contact the annular pipe 134.
[0036] Through the above scheme: After the test is completed, the servo motor 71 of the inner wall scraping structure 7 is started. It is fixed at the lower end of the base frame 1.

After detection, the servo motor 71 of the scraping inner wall structure 7 is activated, and its output pipe drives the connecting rod column 72 to rotate. The connecting rod column 72, through the rectangular rod 73, drives the annular groove 5 to rotate. The rotating frame 74 causes the rubber scraper 75, which is in close contact with the inner wall of the mixing tank 3, to scrape away the residual solids and sediments. At the same time, the suction pump 131 of the spray tank wall structure 13 draws water from the cleaning tank 12, through the long pipe 132 and the short pipe 133 to the annular pipe 134, and sprays cleaning liquid onto the tank wall through the short nozzle 135 and the long nozzle 136 to rinse away the scraped-off residues. Finally, the water is discharged through the discharge pipe 8. Therefore, the detachable feeding structure 6 facilitates feeding and disassembly for cleaning. The scraping inner wall structure 7 and the spray tank wall structure 13 work together to clean the residues on the inner wall of the mixing tank 3. All components work closely together to ensure the smooth progress of the testing work, improve the efficiency and accuracy of the testing, and effectively solve the problem of residue interference in dairy product testing.
