Description

Technical Field

[0001] The utility model relates to the field of equipment for preparing soybean meal fermentation agent, in particular to a device for preparing soybean meal fermentation agent. Background Art

[0002] As a kind of biological feed, fermented soybean meal does not contain antibiotics and is rich in nutrients such as probiotics and lactic acid. It is a good substitute for animal protein such as fish meal. Moreover, the fermentation substrate of fermented soybean meal is soybean meal, which has a wide source, stable quality, and relatively low price. The fermentation process is relatively simple and can achieve large-scale production. Its application in livestock and poultry farming can save a lot of costs without reducing the production performance of livestock and poultry. Lactic acid bacteria is a probiotic preparation widely used in food and feed processing. During the fermentation process, it can produce a large amount of acidic substances and reduce the pH value of the fermentation environment, which is important for reducing the loss of nutrients in food and feed and increasing digestibility. Studies have also pointed out that in addition to inhibiting the reproduction of molds, yeasts and other pathogenic bacteria, lactic acid bacteria can also produce a large amount of lactic acid, regulate the balance of gastrointestinal flora, and have a positive effect on the growth and production performance of animals. There are many types of lactic acid bacteria naturally attached to feed raw materials, but the number is small, usually less than 10 5 cfu / g, so it is difficult to achieve good fermentation and storage effects by only using these natural lactic acid bacteria.

[0003] According to the prior art, the use of composite probiotic preparations to ferment soybean meal can better improve the fermentation quality and reduce the loss of nutrients during the fermentation process, and can also inhibit the growth of mold and reduce the content of mycotoxins. In the process of using composite probiotic preparations to produce fermented soybean meal feed, the production enterprise also needs to use the purchased probiotic preparations for cultivation to achieve the self-production of probiotics, thereby reducing the operating costs of the enterprise. The specific process is divided into: inoculating composite probiotics in the seed tank to form a bacterial solution; then transporting the bacterial solution to the fermentation tank to continue culturing to form a semi-finished mixed bacterial preparation, the semi-finished mixed bacterial preparation is concentrated to form a concentrated mixed bacterial preparation, and the concentrated mixed bacterial preparation is mixed with soybean meal to promote the fermentation of soybean meal to form a semi-finished feed, and then further processed to form different feed products as needed. The composite probiotics include some strains of Lactobacillus plantarum, Enterococcus faecium, Pediococcus pentosaceus, yeast, Bacillus subtilis and Lactobacillus acidophilus. In the process of producing bacterial solution in the seed tank and further culturing the fermentation tank to form a semi-finished mixed bacterial preparation, it is necessary to cultivate the strains at a stable temperature. There are various methods used in the prior art to provide a suitable temperature environment for cultivating bacteria. However, in terms of enterprise application, it should be considered to reduce costs as much as possible while being able to provide a stable temperature suitable for the growth of bacteria, so as to better meet market needs.

[0025] The usage of this product is as follows: Figures 1 to 3 As shown, the following steps are included:

[0026] S1. Add inoculating liquid into the body of the seed tank 1 until the second liquid level sensor 35 installed on the body of the seed tank 1 reaches the preset liquid level height; turn on the stirring device on the body of the seed tank 1 to stir the inoculating liquid in the body of the seed tank 1, and then add probiotic strains into the body of the seed tank 1. The strains undergo a first anaerobic fermentation in the inoculating liquid to form liquid strains. After the first anaerobic fermentation is carried out within a preset time range, it is necessary to pay attention to the parameters fed back by the online chromatograph 36 installed on the body of the seed tank 1 to indirectly judge whether the state of the liquid strains meets the requirements.

[0027] S2. After the state of the liquid strains reaches the requirements, the cultured liquid strains can be used for the next step of culture; specifically, first, liquid culture medium is added into the tank body of the fermentation tank 2 until the second liquid level sensor 35 installed in the tank body of the fermentation tank 2 reaches the preset first liquid level height; then, while the stirring device on the tank body of the seed tank 1 keeps stirring the liquid strains in the tank body of the seed tank 1, liquid strains are added from the tank body of the seed tank 1 into the tank body of the fermentation tank 2 until the second liquid level sensor 35 installed in the tank body of the fermentation tank 2 reaches the preset second liquid level height. finally, turn on the stirring device on the tank body of the fermentation tank 2 to carry out a second anaerobic fermentation under stirring of the liquid bacteria and liquid culture medium in the tank body of the fermentation tank 2. After the second anaerobic fermentation is carried out within a preset time range, attention should be paid to observing the parameters fed back by the online chromatograph 36 installed on the tank body of the fermentation tank 2 to indirectly judge the state of the liquid bacteria until the parameters fed back by the online chromatograph 36 installed on the tank body of the fermentation tank 2 reach the preset required range, and the probiotic semi-finished product in the tank body of the fermentation tank 2 is sent to the next process for processing.

[0028] In the first anaerobic fermentation in step S1, it is necessary to continuously deliver circulating water to the jacket of the seed tank 1 to keep the first anaerobic fermentation process stable; in step S2, it is necessary to continuously deliver circulating water to the jacket of the fermentation tank 2 to keep the first anaerobic fermentation process stable; the specific circulating water supply process is as follows:

[0029] First, the circulating water temporarily stored in the first buffer tank 6 is driven by the boost filtering device in working state and is divided into two parts, namely, the first part of circulating water and the second part of circulating water. The first part of circulating water is continuously transported to the third buffer tank 9 and is continuously transported to the high-pressure steam in the third buffer tank 9 through the steam delivery pipe 10 for direct heat exchange to form high-temperature circulating water. The third buffer tank 9 continuously receives the first part of circulating water and continuously delivers the high-temperature circulating water to the second buffer tank 8. During this process, the first liquid level sensor 29 on the third buffer tank 9 always remains within the preset liquid level height range, and the delivery volume delivered to the upstream steam delivery pipe 10 keeps the third temperature sensor 37 on the third buffer tank 9 always within the preset temperature range. The second part of circulating water is continuously delivered to the second buffer tank 8, the first booster pump 16 is turned on and the first stop valve 20 is kept in a closed state, the second part of circulating water entering the second buffer tank 8 forms a first circulating liquid flow through the circulating water pipe 15, and the high-temperature circulating water delivered by the third buffer tank 9 to the second buffer tank 8 is continuously delivered to the first circulating liquid flow, thereby causing the temperature of the first circulating liquid flow to rise until the temperature parameter feedback by the first temperature sensor 17 reaches the preset range.

[0030] Then, when the temperature parameter fed back by the first temperature sensor 17 reaches the preset range, the temperature-adjusting water is formed in the second buffer tank 8, the first stop valve 20 is opened and the opening of the first regulating valve 13 on the first circulating water delivery branch pipe 3 connected to the seed tank 1 is adjusted, or the first stop valve 20 is opened and the opening of the first regulating valve 13 on the first circulating water delivery branch pipe 3 connected to the fermentation tank 2 is adjusted. At this time, the temperature-adjusting water transported outward from the bottom of the second buffer tank 8 is pressurized by the first booster pump 16 and is divided into two parts again, namely the first part of temperature-adjusting water and the second part of temperature-adjusting water, and the first part of temperature-adjusting water still remains through the circulating water pipe 1 5 is used to transport and maintain the first circulating liquid flow, and the first circulating liquid flow continuously receives the second part of the circulating water and the high-temperature circulating water continuously transported by the third buffer tank 9 to the second buffer tank 8; the second part of the temperature-adjusted water is transported to the jacket of the seed tank 1 or the jacket of the fermentation tank 2 and then returned to the first buffer tank 6 through the circulating water return main pipe 5 to form a second circulating liquid flow, so that the second part of the temperature-adjusted water is used to heat the seed tank 1 or the fermentation tank 2 until the first anaerobic fermentation process in the tank body of the seed tank 1 is completed or the second anaerobic fermentation process in the tank body of the fermentation tank 2 is completed.

[0031] Through this embodiment, by utilizing the high-pressure steam provided by the boiler built in a conventional feed processing plant as a heat source for heating circulating water, high-temperature circulating water is formed and mixed with unheated circulating water to form a suitable heat source to maintain the heat demand of the first anaerobic fermentation process in the tank body of the seed tank 1 or the heat source demand of the second anaerobic fermentation process in the tank body of the fermentation tank 2. Although the structure is slightly complicated, the steam thermal energy used does not require additional equipment. In the formal operation stage, only steam thermal energy and electrical energy to maintain the operation of the boosting and filtering device and the electrical energy to maintain the operation of the first boosting pump 16 are required. This product can be realized. Since electric heating is not used, the power consumption is correspondingly low, thereby reducing the power consumption.

[0032] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
