[0033] When in use, the bottom of the material plate 8 is also connected to a motor 14 for controlling its rotation, so that the material discharge or drainage can be controlled.

[0034] In one embodiment:

[0035] The dewatering assembly includes a plurality of vacuum rods 16 connected to the side walls of the discharge bin 5 and a vacuum drainage pump 15 connected to the ends of the vacuum rods 16. The side walls of the discharge frame 6 are connected with a plurality of water-permeable holes 17 for accommodating the seepage of water, and the bottom end of the discharge bin 5 is provided with a discharge port. The bottom end of the discharge frame 6 is provided with a lower sealing cover 18 in conjunction with the discharge port, and the bottom end of the lower sealing cover 18 is connected with a hydraulic drive cylinder 19.

[0036] When the present invention is implemented,

[0037] The invention comprises the following steps: step 1: selecting sweet potatoes, and using fresh sweet potatoes free of pests and diseases, and free of decay as raw materials; step 2: pre-treating the sweet potato raw materials; step 3: opening a top cover 2 and feeding the treated sweet potatoes into a grinding box 1; step 4: introducing steam through a steam head, and starting a motor 13 so that a crushing fan blade 12 grinds and crushes the sweet potatoes; step 5: discharging condensate of the steam through a drain port, and starting a vacuum drainage pump 15 to absorb liquid; step 6: starting a motor 2 14 after grinding and mud making so that an opening 1 9 overlaps with an opening 2 10, and the sweet potato mud falls into a discharging frame 6; step 7: after the vacuum drainage pump 15 continues to absorb liquid through a vacuum rod 16, it starts a hydraulic drive cylinder 19 to contract, and the discharging frame 6 is taken out; and step 8: sending the sweet potato mud in the discharging frame 6 to a rice grain mold for drying and forming.

[0038] The sweet potato pretreatment in step 2 includes soaking in clean water for 15 to 30 minutes, peeling the sweet potatoes, cutting the peeled sweet potatoes into pieces and steaming them, the pieces being 2 to 3 cm in size, the steam temperature in step 4 being 100 to 120° C., and the steaming is performed once every 5 minutes, and the water content of the sweet potato puree is controlled at 40 to 50% in step 7, and the drying temperature in step 8 being 60 to 80° C., and the drying time being 6 to 10 hours.

[0039] Soak the selected sweet potatoes in clean water for 15-30 minutes to soften the impurities such as mud on the surface. Rinse the sweet potatoes with running water, remove the skin of the sweet potatoes manually or mechanically, and cut them into even-sized blocks with a side length of 2-3 cm. Send the processed sweet potato blocks into the grinding box, pour them slowly and evenly, and spread them around the crushing blades to ensure the consistency of the crushing effect. Close the top cover of the grinding box and seal it to prevent steam leakage. Control the temperature at about 100-120℃ to make its texture softer, so that the crushing motor can drive the crushing blades to rotate at high speed to grind the sweet potato blocks. The rotation speed of the crushing fan blade is 1000-1500 rpm, and the sweet potato is gradually crushed into fine particles until sweet potato puree is formed. At the same time, the drainage hole cooperates with the vacuum suction to suck out the remaining small amount of liquid and water in the grinding box, further reducing the water content of the sweet potato puree, making the texture of the sweet potato puree thicker, and facilitating the subsequent molding and drying treatment. At this time, start the second motor, and the second motor makes the opening one and the opening two gradually overlap to discharge. After the sweet potato puree falls into the discharge frame, the vacuum drainage pump continues to absorb liquid from the sweet potato puree in the discharge frame through the vacuum rod, further removing excess water therein, so that the water content of the sweet potato puree reaches the requirement suitable for molding, and the water content is controlled at about 40%-50%. At this time, the discharge is completed. In the molding area, the sweet potato puree is evenly filled into the pre-prepared rice grain mold, and a hot air dryer, a vacuum dryer or a microwave dryer is selected according to the actual production needs and conditions. The temperature is 60-80°C, and the drying and molding are carried out.
