Description

Technical Field

[0001] The invention belongs to the technical field of microbial culture medium, and in particular relates to a system and method for preparing carbon source raw materials for microbial culture medium. Background Art

[0002] In the carbon source raw material formulation system of microbial culture medium, cottonseed protein embryo flake drying is a key pretreatment step because it directly affects the quality of the culture medium and the effect of microbial growth. The traditional method of drying cottonseed protein embryo flakes usually uses a fixed dryer, which faces some technical challenges in actual operation.

[0003] First, in order to ensure that the cottonseed protein flakes can be dried evenly and avoid partial overdrying or excessive humidity, operators need to manually lay the flakes flat on the conveyor belt of the dryer. This manual laying operation is not only time-consuming and labor-intensive, but also difficult to maintain consistency during batch processing, thus affecting the drying efficiency and flake quality.

[0004] Secondly, traditional dryers are often designed with single-angle hot air circulation, which means that only one side of the cottonseed protein embryo can fully contact the hot air, resulting in uneven drying. This drying method not only reduces the drying efficiency, but also may cause some parts of the embryo to deteriorate in quality due to over-drying, while other parts cannot reach the low moisture content required by the microbial culture medium due to insufficient drying. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a system and method for preparing carbon source raw materials for a microbial culture medium, so as to solve the problem that the manual leveling operation proposed in the above-mentioned background technology is not only time-consuming and labor-intensive, but also difficult to maintain consistency during batch processing, thereby affecting the drying efficiency and the quality of the embryo flakes. Traditional dryers are often designed for single-angle hot air circulation, which means that only one side of the cottonseed protein embryo flakes can fully contact the hot air, resulting in uneven drying. This drying method not only reduces the drying efficiency, but may also cause some parts of the embryo flakes to deteriorate in quality due to excessive drying, while other parts cannot reach the low moisture content required by the microbial culture medium due to insufficient drying.

[0013] Preferably, the output end of the driving motor is transmission-connected with a threaded screw, and the surface of the threaded screw is threadedly connected with a connecting structure.

[0014] Preferably, a non-contact humidity sensor is installed inside the connection structure.

[0015] The method of the carbon source raw material batching system of microbial culture medium comprises the following steps:

[0016] Step 1: Processing of peanuts and soybeans: Peanuts and soybeans are ground into powder using a peeling machine and a micronizer to increase their surface area for easy contact and decomposition by microorganisms; optional steps include acid hydrolysis or enzymatic hydrolysis of proteins, and fermentation of complex carbohydrates and proteins using specific microorganisms to increase their availability;

[0017] Step 2: Shell the cotton seeds with a toothed roller sheller, soften the cotton kernels with a drum softener and roll them into embryo sheets; then, dry them in a drying box, degrease with solvent oil and dephenolize with methanol to finally obtain detoxified cottonseed protein; the upper and both side surfaces of the drying box are provided with drying ports, and are equipped with air guide plates and conveyor belts to achieve fast and uniform drying, and the material thickness is adjusted by a scraper to ensure the drying effect; in addition, the drying box is also equipped with a non-contact humidity sensor and a material discharge buffer plate, which are used to detect humidity and protect material integrity respectively;

[0018] Step 3: Production of peanut protein / soy protein: After cleaning, drying, peeling and embryo rolling of peanuts / soybeans, leaching is performed using an ethanol-hexane mixed solvent, and the peanut protein / soybean protein is obtained by desolventizing;

[0019] Step 4: Compounding: Mix cottonseed protein, peanut protein and soybean protein in a mass ratio of 4-6:2-4:1-3, and homogenize and blend to ensure a uniform mixture;

[0020] Step 5: Secondary compounding: Calculate the amount of trace elements to be added according to product requirements, and use an automatic control system to accurately add the amount, and perform a second homogenization compounding with the protein material after the first compounding;

[0021] Step 6: Culture medium powder production: lift the prepared materials to the upper layer and carry out preliminary crushing, screening, second grinding, adjustable air duct screening, micronizer crushing, magnetic separation, and airflow treatment steps to finally obtain culture medium powder with a fineness of 120-180 mesh and seal it for packaging.

[0022] Compared with the prior art, the present invention provides a system and method for preparing carbon source raw materials for microbial culture medium, which has the following beneficial effects:

[0023] First, the present invention provides structures such as scrapers, and when drying cottonseed protein embryo flakes, the cottonseed protein embryo flakes are poured into the limiting grooves on the surface of the conveyor belt through the hopper or directly, and the cottonseed protein embryo flakes are conveyed to the direction of the drying machine box by the conveyor belt. When the cottonseed protein embryo flakes pass the position of the scrapers, the cottonseed protein embryo flakes are flattened by the scrapers, thereby ensuring that the thickness of the cottonseed protein embryo flakes at the front, back, left and right positions when the cottonseed protein embryo flakes enter the drying machine box for drying is relatively uniform, and at the same time, the threaded rod can be rotated by the handle to drive the connecting rod and the scraper to be raised and lowered, so as to achieve the purpose of adjusting the thickness of the cottonseed protein embryo flakes entering the drying machine box, making the system more convenient to use, and effectively avoiding the problem that the manual flattening operation is not only time-consuming and labor-intensive, but also difficult to maintain consistency during batch processing, thereby affecting the drying efficiency and the quality of the embryo flakes;

[0024] Second, the present invention provides an air guide plate, and when the cottonseed protein embryo sheet is dried through the drying box, hot air is blown out through the drying ports provided at the upper end and the left and right ends for drying, and the hot air is conducted to the lower surface of the conveyor belt through the air guide plate to dry the lower surface of the cottonseed protein embryo sheet, thereby achieving the purpose of drying the surrounding surfaces of the cottonseed protein embryo sheet at the same time, making the drying more rapid and uniform, and effectively avoiding the problem that the traditional dryer is often designed as a single-angle hot air circulation, which means that only one side of the cottonseed protein embryo sheet can fully contact the hot air, resulting in uneven drying. This drying method not only reduces the drying efficiency, but also may cause some parts of the embryo sheet to deteriorate in quality due to over-drying, while other parts cannot reach the low moisture content required by the microbial culture medium due to insufficient drying;

[0025] Third, the humidity sensor of the present invention is used to drive the threaded screw to rotate through the driving motor, thereby driving the connecting structure to move up and down inside the lifting groove, and finally driving the humidity sensor to adjust the height, so that the humidity of the cottonseed protein embryo flakes after the drying process is directly detected through the humidity sensor;

[0026] Fourth, the present invention provides a material discharge buffer plate, and the material discharge buffer plate is an arc-shaped plate structure. After the cottonseed protein embryo pieces are dried in the drying box, they are discharged through a conveyor belt. After the conveyor belt conveys the cottonseed protein embryo pieces out of the equipment, the cottonseed protein embryo pieces fall on the surface of the material discharge buffer plate. The material discharge buffer plate provides buffering, thereby ensuring the integrity of the cottonseed protein embryo pieces, and protecting the cottonseed protein embryo pieces.

[0027] Fifth, the present invention uses the transmission gear, meshing teeth and meshing grooves to convey the cottonseed protein embryo flakes through the conveyor belt during use, and the transmission gear is driven to rotate by the driving motor. When the meshing teeth and the meshing grooves on the surface of the transmission gear mesh with each other, the conveying roller is driven to rotate and conveyed through the conveyor belt. When the meshing teeth are away from the meshing grooves, the driving motor drives the transmission gear to continue to rotate, and the conveyor belt stops conveying at this time. The cottonseed protein embryo flakes in the drying box are dried through the drying port inside the drying box. After a period of drying, the meshing teeth continue to rotate until they mesh with the meshing grooves. The conveyor belt continues to convey the cottonseed protein embryo flakes, and the next round of cottonseed protein embryo flakes are conveyed to the inside of the drying box for drying. The cottonseed protein embryo flakes after drying are discharged, thereby achieving the purpose of intermittent conveying. BRIEF DESCRIPTION OF THE DRAWINGS
