Description

Technical Field

[0001] The invention relates to the technical field of rapid food detection, in particular to rapid food detection equipment with a self-cleaning function. Background Art

[0002] Food testing equipment is a tool used to detect the various ingredients, properties and possible contaminants of food.

[0003] Existing food testing equipment can be used to detect various ingredients in food, such as protein, fat, vitamins, minerals, etc. It performs quantitative analysis by measuring the degree of absorption of light of different wavelengths by the substance.

[0004] Principle: When a beam of parallel monochromatic light passes through a solution containing an absorbing substance, the absorbance of the solution is proportional to the concentration of the absorbing substance and the optical path length. The detection device uses the light emitted by the light source to pass through the monochromator to produce monochromatic light. After the monochromatic light passes through the sample cell, it is received by the photodetector and converted into an electrical signal, thereby measuring the absorbance.

[0005] When using existing food testing equipment, the food to be tested needs to be placed in a test tube first. After the test is completed, the test tube needs to be taken out and cleaned before it can be stored. In the process of taking the test tube out of the testing device, when the test tube shakes or tilts, the test liquid inside will splash to the outside, causing external pollution. The staff needs to clean the test liquid in time, and then clean the test tube, which undoubtedly increases the workload of the staff.

[0045] In one embodiment, the rotating cleaning assembly 52 includes a waterproof cover 23, a rotating cylinder 36, a gear 41, and a second motor 42.

Since the first bevel gear 32 is meshed with the second bevel gear 33, the first bevel gear 32 rotates, and the rotation of the first bevel gear 32 drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the pulley 27 to rotate, and the pulley 27 drives the belt 28 to move.

When the belt 28 drives the first brush 25 to move and rotate, the turning block 24 turns the first brush 25 passing by so that it falls into the waste liquid tank 12, thereby preventing the test food from being hidden between the gaps of the first brush 25 and affecting the cleaning of the next test tube 13 by the cleaning module 11; S6: Sending pure water into the water spray box 26 through the pure water pipe 22, and spraying it out through the water spray port to finally flush the inside of the test tube 13; S7: When a test tube 13 is cleaned, the first motor 19 drives the turntable 17 to rotate, so that the test tube 13 leaves the cleaning area. At this time, the infrared receiver 10 cannot receive the infrared rays emitted by the infrared transmitter 9, and the rotating drive member 16 drives the placement tube 14 to rotate and reset. Subsequently, it is only necessary to manually press the clamping switch 8 to release the clamping drive member 15 from fixing the test tube 13, so that the clean test tube 13 can be taken out; The present invention can clean the test tube 13 directly after the test is completed, so as to avoid the test tube 13 from shaking or tipping over during the transfer to the clean water tank, causing the internal test liquid to splash to the outside and cause pollution. There is no need to perform subsequent cleaning work on the test tube 13, and the test tube 13 is automatically cleaned, which effectively reduces the workload of the staff.
