Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feed production technology, and specifically relates to a wet-based fermentation raw material addition device and fermentation tank. Background Technology
[0002] Wet-based fermentation is a process that uses microbial fermentation to transform traditional soybean meal into a more nutritious feed ingredient. The key to this process lies in selecting suitable microbial strains, such as lactic acid bacteria and yeast, which can break down anti-nutritional factors in soybean meal, improving its digestibility and nutritional value. To enrich the taste and nutritional composition of the fermented feed, small amounts of additives (vitamins, amino acids), minerals (limestone powder, shell powder, bone meal), and functional ingredients (preservatives, acidifiers) are added. Currently, the most common method is to directly add the ingredients to the fermentation tank and then mix the small amounts of raw materials with the large amount of raw material (soybean meal) within the fermentation tank. However, due to the large volume of the fermentation tank, it is difficult to evenly mix the small amounts of raw materials. Therefore, to address this problem, a wet-based fermentation raw material addition device that can pre-mix small amounts of raw materials is provided. Utility Model Content
[0003] The purpose of this invention is to provide a wet-based fermentation raw material addition device and a fermentation tank.
[0004] This utility model is achieved through the following measures: a wet-based fermentation raw material addition device, characterized in that it includes an annular plate, an inner annular plate and an outer annular plate are respectively provided on the inner and outer edges of the annular plate, the outer annular plate is higher than the inner annular plate and a sealing top plate is provided at the top, a stirring shaft is rotatably provided at the center of the sealing top plate, a driving rod is fixedly provided on the stirring shaft, a push plate is provided at one end of the driving rod between the inner annular plate and the outer annular plate, and a stirring plate is provided at the other end between the inner annular plate and the outer annular plate, a plurality of strip-shaped openings are provided on the stirring plate, the inner and outer sides of the push plate are in contact with the inner annular plate and the outer annular plate respectively, and the bottom is in contact with the annular plate;
[0005] A discharge port is provided on the annular plate and located between the inner and outer annular plates. An ear plate is fixedly provided on the upper inner side of the inner annular plate. Gear 1 and gear 2 are rotatably provided on the ear plate and mesh with each other. Gear 2 is located inside gear 1 and a material outlet baffle that can block the discharge port is fixedly provided at the lower end of the gear shaft of gear 2. At least two tooth blocks that mesh with gear 1 are fixedly provided at either end of the drive rod. Gear 1 is a partial gear.
[0006] The upper end of the stirring shaft extends out of the sealing top plate and the extended end is connected to a motor with a speed reducer.
[0007] The annular space formed by the inner and outer ring plates enables premixing of small quantities of raw materials. The stirring plate improves mixing uniformity through the strip-shaped inlet. The intermittent meshing of gear one with the drive rod controls the opening of the feed inlet baffle. The partial gear design ensures that the drive rod triggers gear two only at a specific angle. After the feed inlet baffle opens, gear one disengages, and the main stirrer continues to operate unaffected. The push plate slides close to the inner and outer ring plates and the annular plate to remove residual raw materials in the premixing zone. The angle of the partial gear is generally 160 degrees.
[0008] The sealing top plate is provided with an exhaust port, a pressure gauge interface and several feed pipes, of which at least one feed pipe is located between the inner ring plate and the outer ring plate, and also includes a feed pipe located inside the inner ring plate.
[0009] An observation port is provided on the sealed top plate at a position corresponding to gear one and gear two, and the observation port is sealed by a removable cover plate. The observation port can be used to reset the material outlet baffle, which can be manually reset by rotating gear two.
[0010] A fermenter with the aforementioned wet-based fermentation raw material addition device is characterized in that it includes a tank body with an open upper end, and flanges are fixedly provided on the outer edge of the upper end of the tank body and the outer edge of the annular plate, and the two flanges are connected by a number of bolts.
[0011] A stirrer located inside the tank is fixedly mounted at the lower end of the stirring shaft. The same motor drives the stirring plate in the premixing zone and the stirrer in the main tank, reducing energy consumption and providing synchronous control. The stirring shaft and the stirrer are coaxially fixed.
[0012] Both the annular plate and the tank body have annular grooves for placing sealing rings on their contact surfaces. This double-sealing-ring design prevents fermentation gas leakage and maintains the stability of the anaerobic / aerobic environment inside the tank.
[0013] Several support legs are fixedly installed on the lower outer wall of the tank.
[0014] A discharge port is provided at the bottom of the tank.
[0015] How to use:
[0016] Secure the additive device to the top of the tank using flange bolts, and check that the sealing ring is tightened. Connect the motor power supply, and add a large quantity of raw material through the inlet on the inner side of the inner ring plate. Add various small quantities of raw materials through the feed pipe between the inner and outer ring plates. Start the motor; the stirring shaft drives the stirring plate to rotate, and the strip-shaped nozzle cuts the raw material to improve the mixing uniformity of the small quantities. The stirring shaft simultaneously drives the agitator to stir and disperse the large quantity of raw material. When the drive rod rotates, the teeth at its end mesh with gear one, driving gear two to rotate, and the discharge port baffle opens. The premixed raw material falls into the main tank through the discharge port, and the pusher plate simultaneously removes residual raw material in the annular area. After gear one disengages, the discharge port baffle remains open, and the main tank agitator continues to run, mixing the small and large quantities of raw materials.
