Description

Technical Field

[0001] The present invention relates to the technical field of meat product detection, and in particular to a food detection device for food production. Background Art

[0002] China is the largest meat product producer and consumer in the world. With the increase in the output and variety of red meat products (such as pork, beef, mutton, etc.), the detection of meat eating quality has attracted great attention from consumers and meat enterprises. There may be harmful substances such as microorganisms, heavy metals, and pesticide residues in meat products, which pose a potential threat to human health. Through detection, unqualified products can be discovered and processed in time to prevent them from entering the market, thereby protecting the health of consumers. Detecting the quality and safety of meat products can ensure that food production is in a legal state, enabling enterprises to have the right to sell food. At the same time, strict detection systems can crack down on illegal addition and counterfeiting behaviors, maintaining fair competition and order in the market.

[0003] At present, the detection methods of conventional meat product detection devices are single. The detection mainly uses sensory and physical and chemical methods. Sensory detection mainly evaluates the quality of meat by human chewing and tasting, which is greatly affected by subjective factors and is prone to errors, and cannot meet the current detection requirements; therefore, we propose a food detection device for food production to solve this problem.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. In the present invention, for a food detection device for food production, by placing the meat product to be detected at the left end of the conveyor belt and starting the conveying motor to drive the conveying roller to rotate clockwise, thereby driving the conveyor belt to run clockwise to achieve the moisture conveyance of the meat product. When the meat product is conveyed to the lower part of the lifting plate, the conveying motor is controlled to stop running, and the first driving motor is started. The first driving motor drives one of the rotating shafts to rotate, and through the transmission of the chain and the two sprockets, drives the other rotating shaft arranged side by side with it to rotate synchronously, and drives the two connecting columns to perform synchronous circular motion through the corresponding rotating arms. The connecting columns drive the lifting plate to move up and down reciprocally through the cooperation of the ear plate, the sliding seat and the slide rail, and realize the up and down movement guidance of the lifting plate through the cooperation of the guide rod and the guide frame. The lifting plate drives the translation plate to move up and down synchronously through the cooperation of the longitudinal rail and the guiding frame. The translation plate drives the moisture detector to move up and down reciprocally, so that the detection probe of the moisture detector is inserted into the meat product. Since the dielectric constant of water is much larger than that of general substances, as long as there is a slight change in the water content of the measured meat product, it will cause a large change in the capacitance of the sensor, thereby judging the moisture content of the meat product;

[0026] 2. In the present invention, for a food detection device for food production, the translation plate drives the cutter to move up and down, so that the cutter cuts the meat product and realizes the detection of the resistance of the cutter during the cutting process through the pressure sensor, thereby judging the freshness of the meat product;

[0027] 3. In the present invention, for the food detection device used in food production, during the reciprocating up and down movement of the lifting plate, the second driving motor and the driving button on its top are driven to move up and down synchronously. When the lifting plate moves to the uppermost position, the control button is squeezed by the top plate, thereby controlling the output shaft of the second driving motor to rotate by a fixed angle and driving the rotating plate to rotate. The rotating plate drives the translation plate to move back and forth through the cooperation with the round rod, the sliding frame and the cross rail, thereby driving the cutting knife and the moisture detector to move horizontally synchronously, so that the translation plate can drive the detection probe and the cutting knife to insert into different positions of the meat product during the downward movement. By repeating the above operation steps, multi-point detection of the meat product can be achieved, reducing the detection error.

[0028] 4. In the present invention, for the food detection device used in food production, the meat product is conveyed into the aggregate hopper through the conveyor belt, and then introduced into the feeding hopper through the aggregate hopper. By starting the third driving motor to drive the driving shaft to rotate, the driving shaft drives the upper crushing knife, the lower crushing knife, the stirring paddle, the sliding cylinder and the stirring blades to rotate. The upper crushing knife and the lower crushing knife are used to crush the meat product, and the solvent required for mixing is introduced through the solvent inlet pipe to mix the solvent with the crushed meat product to form a solution, and the mixing rate is increased by the rotation of the stirring paddle and the stirring blades.

[0029] 5. In the present invention, for the food detection device used in food production, the driving shaft is provided to drive the driving bevel gear to rotate synchronously. The driving bevel gear drives two crankshafts to rotate synchronously through the engagement with two driven bevel gears. The crankshaft drives the support rod and the feeding hopper to reciprocate up and down through the cooperation of the moving seat and the track plate. The feeding hopper drives the conical hopper inside it to move synchronously, thereby driving the meat product inside it to vibrate up and down to facilitate repeated crushing. At the same time, the positioning frame drives the sliding cylinder to vibrate up and down, thereby driving the stirring blades to rotate and vibrate up and down, improving the mixing effect.

[0030] 6. In the present invention, for the food detection device used in food production, by starting the delivery pump, the mixed solution is pumped out through the feed pipe and introduced into the enzyme-linked immunosorbent assay instrument, the Kjeldahl apparatus, the atomic absorption spectrophotometer, and the liquid chromatograph through the delivery pipe and the inlet pipe. The enzyme-linked immunosorbent assay instrument is used to determine the veterinary drug residues and the content of illegal additives in the meat product, the Kjeldahl apparatus is used to determine the protein content of the meat product, the atomic absorption spectrophotometer is used to determine the heavy metal elements, pesticide residues and additives in the meat product, and the liquid chromatograph is used to determine the pesticide residues and conduct qualitative and quantitative analysis of various organic compounds.

[0031] 7. In the present invention, for the food detection device used in food production, through the provided conveying mechanism, feeding mechanism and crushing and mixing mechanism, the automatic conveying and pre-treatment before detection of the meat product can be realized, thus facilitating the detection of the meat product in multiple dimensions and reducing the detection error.

By repeating the above operation steps, multi-point detection of the meat product can be realized, reducing the detection error;
