Description

Technical Field

[0001] This utility model relates to the field of pig feed processing technology, specifically to a fermentation device for fermenting pig feed using tea leaves in a combined crop and livestock farming system. Background Technology

[0002] The combination of tea cultivation and black pig farming is a typical "planting-livestock cycle" ecological agricultural model. It can improve resource utilization and reduce environmental pollution, achieving a win-win situation for both economic and ecological benefits. Waste generated during tea cultivation can be fermented and used as supplementary feed for black pigs, reducing feed costs. Excrement such as manure and urine generated during black pig farming can be composted or treated in a biogas digester and used as organic fertilizer for tea cultivation, replacing chemical fertilizers, reducing chemical pollution, and improving tea quality.

[0003] The tea-pig feed fermentation device is a specialized device for mixing tea by-products with other feed ingredients and then converting them into high-quality pig feed through microbial fermentation. Its core function is to provide suitable temperature, humidity, and ventilation conditions for the fermentation process, promote the reproduction of microorganisms (lactic acid bacteria, yeast, etc.), degrade crude fiber, neutralize astringency, and improve the palatability and nutritional value of the feed.

[0004] A patent with authorization announcement number "CN222758218U" discloses a pig feed fermentation device, including a fermentation box. The top of the fermentation box is provided with a drive box and a feed inlet, and the bottom of the fermentation box is provided with a feed outlet. The inner bottom of the fermentation box is provided with two inclined blocks, and the fermentation box is provided with a cavity, which is located at the bottom of one of the inclined blocks. This utility model, by setting a stirring mechanism, makes the feed and fermentation agent fully mixed, accelerates the fermentation efficiency of the feed, and improves the quality of the feed. By setting a blocking mechanism, the blocking block can be moved up and down repeatedly, which can prevent the feed from clumping and blocking the feed outlet, and at the same time accelerate the feed discharge speed. By setting a discharge mechanism, the discharge and stop discharge can be switched between each other, and the limiting groove increases the bearing capacity of the baffle.

[0005] However, this device has the following shortcomings:

[0006] 1. When processing tea-fermented pig feed, the feed needs to be stirred to ensure uniform mixing and increase the oxygen-receiving surface area. However, the above-mentioned device has poor stirring effect on tea and feed, resulting in poor material flowability. The material is easily pushed to the edge of the tank, affecting the fermentation effect.

[0007] 2. When using the fermentation tank, it is necessary to ensure continuous ventilation to provide oxygen to the feed. Due to the temperature required for fermentation inside the tank, a certain amount of heat remains when the air inside the tank is discharged. The above-mentioned device fails to effectively utilize the heat from the exhaust, resulting in a significant waste of energy. Utility Model Content

[0034] Working principle: When fermenting tea by-products such as tea dregs, broken tea, and tea branches with raw materials such as corn, soybean meal, and wheat bran, the tea by-products can be added to fermentation tank 1 along with other feed. At this time, the hot air blower 31 is started to draw in and heat the air. The hot air is then delivered to the annular pipe 32 through the air guide pipe 33 to raise the temperature inside the tank and reach the temperature required for feed fermentation. The water pump 35 is started to draw water from the water tank 34 and deliver it into fermentation tank 1 through the connecting pipe 36 to mix with the feed. This ensures the moisture required for feed fermentation and provides a good fermentation environment for the fermentation bacteria.

[0035] When hot gas is discharged from the device, it can enter the guide channel 37 through the exhaust pipe. In the guide channel 37, it is divided into three sets of heat exchange tubes 38. At this time, the water in the water tank 34 can exchange heat with the gas in the heat exchange tubes 38. The residual heat in the gas is used to heat the water. When the heated water is injected into the fermentation tank 1 and mixed with the feed, it can optimize the microbial environment and improve the raw material processing efficiency.

[0036] When fermenting feed, the motor 45 can be started to run. The motor 45 can drive the rotating rod 46 to rotate, and then the rotating rod 46 drives the gear 47. Through the meshing of the gear 47 with the internal gear ring 43, the two sets of stirring rods 44 can be driven to rotate, which stirs the feed in the fermentation tank 1, speeds up the mixing of tea by-products and raw materials, improves the uniformity of heat and oxygenation of the feed, and improves the fermentation efficiency.

[0037] When the rotating rod 46 rotates, the screw conveyor rod 51 can be driven to rotate through the belt drive assembly 52. ​​Due to the conical shape of the bottom of the fermentation tank 1, the material can continuously flow towards the center of the bottom of the fermentation tank 1. At this time, the feed can enter the sealed cylinder 24 through the feed inlet 53, and then the screw conveyor rod 51 will continuously convey the feed upward and discharge it from the discharge outlet 54 to the top of the feed, so that the feed will continuously circulate in the fermentation tank 1. The stirring of the stirring rod 44 can prevent the feed from accumulating, improve the fluidity of the feed, and enhance the mixing effect.

[0038] When the device discharges the feed after fermentation, the electric push rod 21 can be activated to move the movable plate 22 upward. Then the movable plate 22 will move the sealing cylinder 24, so that the sealing cylinder 24 can release the blockage of the discharge pipe 23. At this time, the material can be discharged outward through the discharge pipe 23.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
