[0026] Example 1

[0027] like Figures 1-2As shown, this embodiment provides a yam extrusion device, including a peeling device 1, a cooking device 2, a stirring device 3, an extrusion tube 4, and a forming cylinder 5 connected in sequence; this embodiment also includes a control unit, including a main controller, which is connected to modules such as baffle control, cooking time, forming control, and conveyor belt control to achieve unified control of the operation of each device.

[0028] This device provides a fully automated yam processing system that integrates peeling, steaming, mud preparation, and extrusion molding functions. The devices are connected in sequence and work with the control unit to achieve fully automated operation of the entire process of yam processing, from peeling, steaming, stirring to extrusion molding. This can improve production efficiency, reduce manual intervention, and lower labor intensity.

[0029] This device is also equipped with a peel and residue filtration device 6, a biochar preparation device 7, and a control unit. The control unit regulates the operation of each module to realize the automated processing of yam from peeling to shaping, and the peel, residue, and wastewater are recycled.

[0030] The specific structure of the yam extrusion device provided in this embodiment includes:

[0031] The peeling device 1 is equipped with a conveyor motor, a first conveyor belt, a skin peeling device 8, and a rinsing device. The beginning and end of the first conveyor belt correspond to the inlet and outlet of the peeling device 1, respectively. The skin peeling device 8 is located above the first conveyor belt, and the rinsing device is installed at the top of the inside of the peeling device 1. The bottom of the peeling device 1 is connected to the inlet of the skin residue filter device 6, and the outlet of the skin residue filter device 6 is connected to the biochar preparation device 7.

[0032] The peeling device 8 is a rotating peeling brush roller assembly. One or two high-speed rotating food-grade nylon brush rollers or rollers with flexible friction protrusions are installed above or to the side of the conveyor belt (the height is adjusted according to the size of the yam). The brush rollers apply gentle but continuous pressure to the surface of the yam, while the friction protrusions scrape the surface of the yam to remove the skin.

[0033] The rinsing device is a spray pipe that carries low-pressure clean water to rinse away the skin flakes that have just been peeled off the yam, preventing them from re-adhering to the yam or equipment. At the same time, it can lubricate the yam surface, reduce friction and heat generation and secondary adhesion, and maintain the color of the yam.

[0034] It is feasible to install a peeling and scrap collection device 9 at the bottom of the peeling device 1, which is designed in a V-shape or has a certain inclination angle, and the discharge end of the peeling and scrap collection device 9 is connected to the feed end of the peeling and scrap filtration device 6.

[0035] The feasible solution is to install a third conveyor belt inside the sludge filtration device 6, with a wastewater storage area 11 below the third conveyor belt. Both the first and third conveyor belts are equipped with several grids, with the grid density of the third conveyor belt being less than that of the first conveyor belt. The sludge is filtered through the grids in a graded manner, the solids are used to produce biochar, and the wastewater is purified and recycled.

[0036] The implementable method also includes a water storage device 10, a rinsing device, a cooking device 2 and a wastewater storage area 11, all of which are connected to the water storage device 10, and a wastewater filtration device 12 is provided between the wastewater storage area 11 and the water storage device 10.

[0037] The cooking device 2 includes a second conveyor belt and baffles disposed inside the cooking device 2. The second conveyor belt and its corresponding motor are disposed inside the cooking device 2. The second conveyor belt has a grid with a discharge port at its end. The baffles are disposed above the second conveyor belt and each baffle is provided with a corresponding driving device. A heating device is disposed at the bottom of the second conveyor belt.

[0038] It is feasible to connect the feed pipe to the flange at the beginning of the extrusion tube 4, install a solenoid valve in the feed pipe, and set a screw rod coaxially inside the tube, which is driven by the motor of the extrusion tube 4. A vortex generator is embedded at the junction of the end of the extrusion tube 4 and the conical extrusion head.

[0039] In practice, the forming cylinder 5 includes a transport channel and several microchannel cooling pipes. The beginning and end of the transport channel are respectively connected to the inlet and outlet of the forming cylinder 5. The microchannel cooling pipes are arranged inside the cylinder wall of the forming cylinder 5, and each of the microchannel cooling pipes is connected to the circulation control system, which is controlled by the forming control module.

[0040] The specific implementation process of this embodiment includes:

[0041] Peeling stage: Yam is transported by the first conveyor belt. During transportation, it is mechanically peeled by the peeling device 8 set above the first conveyor belt. During the peeling process, the peel scraps are washed into the V-shaped peel residue collection device 9 by the washing device, and then further filtered by the peel residue filtration device 6. The peel residue enters the filtration device to separate solid and liquid. The peel scraps are sent to the biochar preparation device 7 by the third conveyor belt. The wastewater is temporarily stored in the wastewater storage area 11. The wastewater in the wastewater storage area 11 passes through the wastewater filtration device 12 and then enters the water storage device 10 for circulation.

[0042] Steaming stage: A heating device is installed at the bottom of the second conveyor belt. After the yam enters the steaming device 2, it passes through the baffle and reaches the second conveyor belt. At this time, the baffle is closed and the heating device is turned on to heat. After heating for a preset time, the second conveyor belt is started. The steamed yam is transported to the mixing device 3 through the second conveyor belt, where water is added and the mixture is stirred to form yam paste.

[0043] Extrusion molding stage: Yam paste enters the extrusion tube 4 through the feed pipe (the flow rate is controlled by a solenoid valve), the auger rod rotates to propel the material, the end vortex generator homogenizes it, the material enters the transport channel of the molding cylinder 5, and is quickly cooled and shaped by the microchannel cooling pipe before being discharged.

[0044] Resource recycling: Wastewater in wastewater storage area 11 is purified by wastewater filtration device 12 and enters water storage device 10; purified water is recycled for rinsing, cooking and stirring processes.

[0045] In this embodiment, continuous automation of peeling, steaming, and extrusion is achieved, reducing manual intervention. Furthermore, wastewater recycling and the resource utilization of peel residue can reduce energy consumption and waste disposal costs.

[0046] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
