Infrared food detector

Abstract

The invention relates to the technical field of food detection and particularly relates to an infrared food detector which comprises a machine body, a detection rail and a controller. Due to the factthat when the infrared food detector operates, food needs to be placed in a fixed position of the detector, professional technical analysis is conducted on infrared spectrum images displayed in the infrared food detector to determine detection results of all components in the food, and in the production process of a food assembly line, detection efficiency of the food detector is greatly improved;the detection step performed by the infrared detector interferes with the normal operation of the assembly line, an additional detection area needs to be occupied, and assembly line type food production efficiency further is influenced; Therefore, through the arranged detection rail, the infrared food detector and food on the conveying belt are in a relatively static state, stable operation of the food on the conveying belt in the infrared detection process is further achieved, operation efficiency of the infrared food detector on an assembly line type food production line is maintained, andtherefore the application effect of the infrared food detector is improved.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to an infrared food detector. Background technique [0002] With the improvement of people's living standards, there are more and more types of food in life, and the resulting food safety issues have become a hot spot of social concern. When infrared spectroscopy is applied to food testing, certain food substances in molecules The vibration or rotation frequency of a group can be consistent with the frequency of infrared light, its molecules absorb energy, and jump from the original ground state vibration energy level to a higher energy vibration energy level, where the light of the wavelength is absorbed by the substance, and the The absorption of infrared light by molecules is recorded by an instrument to obtain an infrared spectrogram. The infrared spectrogram usually uses the wavelength λ or wave number σ as the abscissa to indicate the position of the absorption peak, an...

Problems solved by technology

[0003] When the infrared food detector is running, it needs to place the food in a fixed position of the detector, wait for the infrared spectrum image displayed in it and conduct professional technical analysis on it to determine the detection results of each component in the food, and in the food During the production process of the assembly line, the detection steps performed by the infrared detector interfere with the normal operation of the assembly line, and require an additional detection area, which also affects the food production efficiency of the assembly line

[0004] There are also some technical solutions for infrared food detection in the prior art. For example, a Chinese patent with application number 2019111770934 discloses an infrared food safety detection device, including a casing, which is provided with an inlet cavity , the left end wall of the feeding chamber is provided with a feeding mechanism, the left end wall of the feeding mechanism is provided with a driving mechanism that provides power to the device, and the left end wall of the driving mechanism is provided with a mechanism that can classify the detected food The classification transportation mechanism, when the food needs to be tested for safety, starts the drive mechanism, and the feeding mechanism transports the food into the equipment through the inlet cavity, and then transports the food to the detection position. After the detection is completed, according to the detection result, the The above-mentioned sorting and transportation mechanism transports the food that meets the requirements to the storage chamber, and the food that does not meet the requirements to the collection chamber to complete the food inspection. The detection of group food will not affect each other, and after the detection is completed, the food that meets the requirements and the food that does not meet the requirements are stored separately, which is more intelligent; It takes time to read and analyze the detected infrared spectrum, which affects the smooth flow of the production line
