Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, one of the purposes of the present invention is to provide a pretreatment device for preparing light fermented black beans, referring to Figure 1-Figure 8 As shown, it includes a water cylinder 100, and a water inlet and a water outlet are respectively provided on both sides of the water cylinder 100.

A gathering component 400 is provided above the stirring component 300, and the gathering component 400 is used to drain the insect-infested and floating insect beans to gather the insect beans. Collecting components 500 are provided on both sides of the gathering component 400, and the collecting component 500 is used to collect the insect beans.

[0023] The improvement of this embodiment lies in that the fan blade rod 407 is driven to rotate by the output end of the servo motor 406, and the transmission shaft provided on the surface of the fan blade rod 407 is transmitted through the transmission belt 408, so that the fan blade rod 407 blows the water body, and the water flow inside the hollow box 401 is discharged by suction, so that the water flow on the horizontal plane inside the water cylinder 100 converges to the opening of the hollow box 401, and in the process of water flow gathering, the bad beans are driven to flow to the opening of the hollow box 401, so that the bad beans are drained and gathered in the hollow box 401, which is convenient for the subsequent collection and cleaning of the bad beans.

[0024] Since there are many dust and impurities on the surface of soybeans, it is necessary to ensure that the surface of the fermented black beans is clean and needs to be rinsed during the production process. In the process of washing soybeans, manual stirring is required, which increases the labor intensity of the operators. Therefore, the stirring component 300 includes ear blocks 301 arranged on both sides of the movable frame 202, and rubber roller rods 302 are arranged on the surfaces of the ear blocks 301. The side walls of the rubber roller rods 302 are tightly fitted with the inner wall of the water cylinder 100. When the movable frame 202 moves to drive the ear blocks 301 to move, the rubber roller rods 302 are rotated on the inner wall surface of the water cylinder 100 by friction. A main gear 303 is arranged at the bottom of the rubber roller rod 302, and a slave gear 304 is arranged below the main gear 303. A stirring rod 305 is arranged between the slave gears 304. The stirring rod 305 rotates at the bottom of the movable frame 202. When the stirring rod 305 rotates, the water The soybeans inside the cylinder 100 are stirred, so that the surfaces of the soybeans roll and rub against each other, so that the dust on the surface of the soybeans falls off. When washing the soybeans, the output end of the rotating motor 200 is controlled to drive the first screw rod 201 to rotate, and the moving frame 202 provided on the surface of the first screw rod 201 moves horizontally. The moving frame 202 drives the ear block 301 to move during the movement process, and the rubber roller rod 302 is attached to the inner wall of the water cylinder 100. The rubber roller rod 302 rotates on the inner wall of the water cylinder 100 due to the friction force. The rubber roller rod 302 drives the main gear 303 to rotate coaxially. The main gear 303 drives the slave gear 304 to rotate while rotating, so that the stirring rod 305 automatically stirs the soybeans inside the water cylinder 100, thereby increasing the friction probability between the soybeans and accelerating the removal efficiency of dust and impurities, thereby reducing the labor intensity of the operators.

[0025] During the soybean cleaning process, there are bad beans, i.e., worm-eaten beans, among the soybeans. Since the inside is eroded by insects, they usually float on the water surface during the stirring process. In order to improve the production quality of light fermented black beans, the bad beans need to be removed. Therefore, the gathering component 400 includes a colored hollow box 401 above the stirring rod 305. The hollow box 401 is hollow with a side opening. The hollow box 401 is provided with through holes on the side away from the opening. The through holes are arranged in a row. A breathable plate 405 is provided at the through holes.

A fan blade rod 407 is provided at the output end of the servo motor 406. 5, a fan blade rod 407 is provided at the center, a transmission shaft is provided on the surface of the fan blade rod 407, and a transmission belt 408 is provided between the transmission shafts. In the process of stirring the soybeans, the fan blade rod 407 is driven to rotate by the output end of the servo motor 406, and the transmission shaft provided on the surface of the fan blade rod 407 is transmitted through the transmission belt 408, so that the fan blade rod 407 blows the water body, so that the water flow inside the hollow box 401 is discharged by suction, so that the water flow on the horizontal surface inside the water cylinder 100 is gathered toward the opening of the hollow box 401, and the bad beans are driven to flow toward the opening of the hollow box 401 during the water flow gathering process, so that the bad beans are drained and gathered in the hollow box 401, which is convenient for the subsequent collection and cleaning of the bad beans.

[0026] Considering that when soybeans gather on the surface of the hollow box 401, when the soybeans are adsorbed to the surface of the air-permeable plate 405, the fan blade rod 407 has a poor drainage effect on the water flow, resulting in low collection efficiency of bad beans. Therefore, a second screw rod 402 is provided inside the hollow box 401, and the second screw rod 402 passes through the hollow box 401 and is provided with fixed gears 403 on both sides. The fixed gear 403 moves under the rack 103, and a scraper 404 is provided on the surface of the second screw rod 402.

In a natural state, baffle 503 is clamped and fixed to the collection box 505 in a vertical state with the horizontal plane by the force of torsion spring 504. When scraper 404 scrapes the bad beans adsorbed on the surface of air permeable plate 405, the bad beans are collected into the collection box 505. When the bad beans are collected, baffle 503 is pulled to rotate on the surface of rotating shaft 502, so that baffle 503 stops limiting the collection box 505. The collection box 505 is tilted and taken out, so that the bad beans are quickly collected and cleaned.

[0028] When the soybeans are cleaned, in order to quickly collect the cleaned soybeans, a slope plate 105 is provided at the bottom of the water tank 100.

At the same time, the vibration motor 102 continuously vibrates the surface of the slope plate 105 to prevent the soybeans from accumulating and adhering to the surface of the slope plate 105, thereby improving the collection of the cleaned soybeans.

[0029] When in use, the soybeans to be cleaned are poured into the water cylinder 100, and water is injected into the water cylinder 100 through the water injection port. The output end of the rotating motor 200 is controlled to drive the first screw rod 201 to rotate, and the moving frame 202 provided on the surface of the first screw rod 201 moves horizontally. The moving frame 202 drives the ear block 301 to move during the movement process, and the rubber roller rod 302 is attached to the inner wall of the water cylinder 100. The rubber roller rod 302 rotates on the inner wall of the water cylinder 100 under the action of friction. The rubber roller rod 302 drives the main gear 303 to rotate coaxially. The main gear 303 drives the slave gear 304 to rotate while rotating, so that the stirring rod 305 automatically stirs the soybeans in the water cylinder 100, thereby increasing the friction probability between the soybeans and accelerating the removal efficiency of dust and impurities, thereby reducing the labor intensity of the operators. During the stirring process of soybeans, the fan blade rod 407 is driven to rotate by the output end of the servo motor 406, and the transmission shaft provided on the surface of the fan blade rod 407 is transmitted through the transmission belt 408, so that the fan blade rod 407 blows the water body, so that the water flow inside the hollow box 401 is discharged by suction, so that the water flow on the horizontal surface inside the water cylinder 100 converges to the opening of the hollow box 401, and in the process of water flow gathering, the bad beans are driven to flow to the opening of the hollow box 401, so that the bad beans are drained and gathered in the hollow box 401, which is convenient for subsequent The bad beans are collected and cleaned; when the hollow box 401 moves horizontally, the fixed gear 403 meshes and rotates at the bottom of the rack 103, and the fixed gear 403 rotates to drive the second screw rod 402 to rotate, and the scraper 404 provided on the surface of the second screw rod 402 moves horizontally inside the hollow box 401.
