Description

Technical Field

[0001] The invention relates to the technical field of solid-state fermentation, and in particular to a solid-state fermentation device for producing soybean protein which is convenient for loading. Background Art

[0002] Solid-state fermentation in soy protein production is a process that uses microorganisms to grow and reproduce on a solid matrix to change the properties of soy protein. It uses soy protein as a substrate and adds appropriate microorganisms, such as molds, bacteria, yeasts, etc., to ferment under certain temperature, humidity and ventilation conditions. Microorganisms decompose soy protein by secreting enzymes in a solid environment, causing a series of reactions such as hydrolysis of soy protein to produce nutrients such as bioactive peptides and amino acids, and can also reduce anti-nutritional factors. At the same time, it may produce beneficial ingredients such as organic acids and flavor substances, thereby improving the nutritional value, functional properties and flavor of soy protein. This fermentation method is widely used in food, feed and other fields; Soybean meal is a byproduct obtained after soybean oil is extracted from soybeans. After soybeans are pressed or leached to extract oil, the remaining material is properly processed to form soybean meal. It is rich in protein and is an important source of plant protein. It is often used as a native substrate for soybean protein fermentation. Soybean meal is usually compressed in irregular flakes, which can easily cause blockage during feeding, which is not conducive to feeding during fermentation. In addition, the irregular flake-shaped compressed soybean meal makes it impossible for microorganisms to be fully mixed, which can easily cause a series of problems such as uneven fermentation. Therefore, we proposed a solid-state fermentation device for soybean protein production that is easy to load. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a solid-state fermentation device for soybean protein production that is easy to load, comprising: A bottom plate, the top of which is fixedly connected to a support plate; A fermentation mechanism, wherein the fermentation mechanism is fixedly connected to a side of the support plate away from the bottom plate; Wherein, the fermentation mechanism comprises: A cylinder, wherein the cylinder is fixedly connected to a side of the support plate away from the bottom plate, a top cover is fixedly connected to a side of the cylinder away from the support plate, and an inner side surface of the top cover is set to be circular; A rotating shaft, one end of the rotating shaft close to the bottom plate passes through the bottom of the cylinder, and a stirring blade is fixedly connected to the surface of the rotating shaft; A driving assembly, wherein the driving assembly has a transmission structure for driving the rotating shaft to rotate, and the driving assembly is fixedly connected to the top of the bottom plate; A heating component, which is arranged inside the cylinder and is used to heat the soybean meal inside the cylinder, and the surface of the heating component is fixedly connected to the inner side of the cylinder; A feeding assembly, wherein the feeding assembly has a dispersion structure for dispersing aggregated soybean meal blocks, and the feeding assembly is arranged on a side of the rotating shaft away from the bottom plate, and a surface of the feeding assembly is fixedly connected to a surface of the rotating shaft, and a side of the feeding assembly away from the rotating shaft is slidably connected to an inner side surface of a top cover; The inner side of the top cover is set to be circular, and the cavity formed by the cylinder and the top cover is a dome. The curved surface structure of the dome reduces the ratio of surface area to volume. Under the same volume, compared with the flat top, its heat dissipation area is relatively small, and the speed at which heat is dissipated through the top cover will be slower, which can achieve better insulation effect. The driving component is started, and the driving component drives the shaft to rotate, thereby driving the stirring blade to rotate, and at the same time drives the feeding component to rotate, and starts the heating component. The heating component heats the soybean meal inside the cylinder. The soybean meal and yeast are put in from the top of the top cover and are broken up by the feeding component, so as to avoid the soybean meal clumping that affects the fermentation effect and accumulates inside the cylinder. The stirring blade rotates to stir the soybean meal and yeast inside the cylinder. Thereby, the soybean meal and yeast are fully mixed. At the same time, during the fermentation process, the soybean meal and yeast can be mixed again, so that the nutrients, microbial cells, etc. in the cylinder are fully and evenly mixed, so that the fermentation conditions in each part are consistent, and local nutrient deficiency or excess is prevented, and the stability and efficiency of the fermentation process are ensured. During aerobic fermentation, the contact area between oxygen and the culture medium is increased, so that oxygen can be better dissolved and transferred to the fermentation liquid to meet the metabolic needs of microorganisms. Microbial metabolism will produce waste gas and waste such as carbon dioxide. Stirring can prompt these substances to be discharged as soon as possible to avoid their accumulation in the fermentation liquid and negative impact on microorganisms. It is beneficial to the metabolic activity of cells and ensures the smooth progress of the fermentation process.

During aerobic fermentation, the other feeding branch pipe injects oxygen, and is closed during anaerobic respiration. When feeding, first open the feeding pipe, start the driving component, and finally drive the stirring blade to rotate to break the fermentation raw materials. The liquid produced by fermentation and the crushed fermentation raw materials flow out from the feeding pipe. After the fermentation raw materials can no longer flow out, inject clean water into the upper feeding main pipe, and feed again until the raw materials are completely discharged. Then, through post-treatment such as filtration, powdered fermented soybean protein and mash are obtained.

The rotating shaft 33 rotates, driving the arc-shaped material baffle plates 373 to rotate, and the raw materials fall to the top of the arc-shaped material baffle plates 373 and are initially broken up by the arc-shaped material baffle plates 373, and then enter under the arc-shaped material baffle plates 373 and contact the fan-shaped plate 371 to further break up the raw materials, so that the raw materials can be processed in layers to avoid blockage caused by too much feeding at one time, and the arc-shaped material baffle plates 373 are bent toward the side near the axis of the rotating shaft 33, and the gap generated by the rotation can be used for the passage of uncompacted soybean meal, thereby reducing the breaking pressure and ensuring rapid feeding.

[0030] When in use, the feeding main pipe 38 is used to connect the soybean meal conveying pipeline, one feeding branch pipe 310 is used to connect the oxygen conveying pipeline, and the other feeding branch pipe 310 is used to connect the yeast conveying pipeline. The soybean meal is fed from the feeding main pipe 38, and one feeding branch pipe 310 is used to inject yeast. The rotation of the rotating shaft 33 drives the fan plate 371 to rotate, drives the fan-shaped curved plate 372 to rotate, and drives the arc-shaped baffle plate 373 to rotate. The raw material falls to the top of the arc-shaped baffle plate 373 and is initially broken up by the arc-shaped baffle plate 373, and then enters under the arc-shaped baffle plate 373 and contacts with the fan plate 371 to further break up the raw material and spread it around under the action of centrifugal force. The raw material is evenly covered on the inside of the cylinder 31, and the fan-shaped curved plate 372 scrapes the inner side of the top cover 32 to scrape off the adhered soybean meal powder when feeding. During aerobic fermentation, the other feeding branch pipe 310 injects oxygen The motor 355 is started, and the output end of the motor 355 drives the rotating shaft 354 to rotate, thereby driving the transmission of the conveyor belt 353, thereby driving the transmission of the conveyor belt 353, thereby driving the shaft sleeve 352 to rotate, driving the rotating shaft 33 to rotate, and finally driving the stirring blade 34 to rotate. The stirring blade 34 rotates to stir the soybean meal and yeast inside the cylinder 31, so that the soybean meal and yeast are fully mixed. The stirring blade 34 rotates, driving the scraper 311 to rotate, thereby scraping the inner side of the cylinder 31. When unloading, first open the unloading pipe 39, and the stirring blade 34 rotates to break the fermentation raw materials. The liquid produced by the fermentation and the crushed fermentation raw materials flow out from the unloading pipe 39. After the fermentation raw materials can no longer flow out, inject clean water into the upper feeding main pipe 38, and unload again until the raw materials are completely discharged, and then obtain powdered fermented soybean protein and mash through post-treatment such as filtration.
