[0002] Sweet potato is a high-yield and highly adaptable food crop that is closely related to industrial and agricultural production and people's lives. In addition to being a staple food, it is also an important raw material for food processing, starch and alcohol manufacturing industries. The roots, stems and leaves are excellent feed. Sweet potato flour is suitable for all ages and is deeply loved by everyone.

[0003] When it is necessary to process the sweet potatoes into potato flour, the sweet potatoes need to be cleaned first, then crushed by a grinder, and then the potato flour is extracted by stirring and settling. In the prior art, the sweet potatoes are generally washed manually before grinding. Usually, workers are required to wash the sweet potatoes in water with their hands or a brush, and wash them repeatedly. When a large number of sweet potatoes need to be washed, the method of washing them one by one will greatly slow down the work efficiency, and the efficiency of manual washing is not consistent with the grinding of the grinding device. This also leads to the fact that the sweet potatoes are generally washed in batches and then the grinding device is started to grind them in large quantities at one time. The two are carried out in steps. In addition, sweet potatoes are root crops. They are affected by the environment, soil, fertilizer, etc. during growth, and their size and shape are unstable.

After a certain amount is collected, it is transferred by the staff for filtering and screening for starch production and collection, and the juice in the box can also be poured into the screen 81 of the next process and directly filtered using the screen 81.

[0025] As a further configuration of the above scheme, the cleaning component 3 includes a cleaning cylinder 31, a circulating water pipe 32, a washing barrel 33, a rotating motor 34 for driving the washing barrel 33 to rotate, and a cylinder part 35 for driving the washing barrel 33 to dump the sweet potato raw materials. The cleaning cylinder 31 has a plurality of grooves 36 at the bottom, and the circulating water pipe 32 is used to extract the middle layer of water in the cleaning cylinder 31 and then circulate it and spray it on the washing barrel 33.

[0026] As a further configuration of the above scheme, the crushing component 4 includes a crushing knife group 41, a power mechanism 42 for driving the crushing knife group 41, and a rotating roller 43 fixed with the crushing knife group 41 and driven to rotate by the power mechanism 42. The crushing component 4 is arranged at the end of the feeding component 2. The feeding component 2 transports the sweet potato raw material and makes it fall onto the crushing knife group 41. The crushing knife group 41 driven by the power mechanism 42 is relatively stirred to crush and crush it, and after passing through the crushing knife group 41, it falls into the crushing and grinding device 6 from below. The pulping knife group 63 is used for secondary grinding of the sweet potato raw material chopped by the crushing knife group 41. The ground sweet potato slurry falls on the filter conveyor belt 65. The filter conveyor belt 65 includes a mesh conveyor belt sheet and a box-type protective cover 651. The box-type protective cover 651 is set outside the mesh conveyor belt sheet, and is used to introduce the starch water flowing down from the sweet potato slurry and the sweet potato slurry falling from the mesh of the mesh conveyor belt sheet into the collecting tank 64.

[0027] As a further configuration of the above scheme, the screen 81 of the filtering and screening powder assembly 8 of the present invention is arranged at the end of the filter conveyor belt 65 to collect the sweet potato slurry transmitted by the filter conveyor belt 65, the water pump 86 draws water from the overflow tank 85 and sprays it on the upper end of the screen 81 to wash the sweet potato slurry, the stirring member 82 is used to stir the sweet potato slurry in the screen 81, the upper end of the overflow tank 85 is provided with an overflow trough connected to the upper end of the slurry tank 83, and the bottom of the slurry tank 83 is also provided with an ultrasonic device to accelerate the sedimentation of starch. As set up above, when the filtering and screening powder assembly 8 of the present invention is working, the conveying structure at the front end delivers the raw materials into the screen 81, and the water pump 86 continuously pumps Take the water in the overflow tank 85 and spray it into the screen 81 to moisten the sweet potato slurry. The water is mixed with the sweet potato slurry to flow into the slurry tank 83 with the starch on it. After the liquid level in the slurry tank 83 of this embodiment reaches a certain height, the water will flow into the overflow tank 85 through the overflow component 84 to ensure that the water in the slurry tank 83 that continuously flows with starch water will not overflow. An ultrasonic device is also set at the bottom of the slurry tank 83. Under the action of the ultrasonic device, the starch in the water is easier to settle, so that the upper layer of water is relatively clear and the starch content of the overflowing water is lower. The overflow tank 85 collects the overflowing water, and then pumps it away through the water pump 86 for cyclic spraying above the screen 81.

[0028] With the sweet potato grinding device of the present invention, the staff only needs to put the raw materials into the washing barrel 33 at the cleaning component. The washed sweet potatoes are driven by the cylinder 35, and the washing barrel 33 is lifted on one side. The lifting process can drain most of the water, so that the sweet potatoes inside fall on the feeding component 2. The transmission process of the feeding component 2 can also further dry the water on the surface of the sweet potatoes. As shown in the above-mentioned structure, after the sweet potato raw materials are fed into the crushing knife group 4 of the present invention through the feeding component 2, they are first preliminarily cut into blocks from the whole fruit by the crushing knife group 41, and then the block sweet potatoes fall into the crushing and grinding device 6. It is worth noting that the purpose of the setting of cutting into blocks first and then crushing in this embodiment is to avoid the accumulation of irregular-shaped and sized sweet potato fruits at the pulping knife group 63 due to their own shape and size when crushed. After cutting into uniform small pieces, the pulping knife group 63 is used for grinding to improve work efficiency and speed up the grinding speed. The filter conveyor belt 65 located below the pulping knife group 63 can initially separate the plant fibers and juice that constitute the sweet potato slurry. The principle is as described above. The mesh conveyor belt piece can facilitate the sweet potato juice to flow into the water collecting box 64, and a box-type protective cover 651 is provided to collect the juice flowing down during the transmission process. The further design feature of this embodiment also includes the filtering and screening powder component 8. This feature is that after the net bag-shaped screen 81 collects the sweet potato raw materials, the stirring element 82 arranged therein stirs them, and the water pump 86 pumps water to continuously rinse the raw materials with water, so that the starch can be better and more thoroughly collected into the slurry tank 83 for subsequent collection by staff and drying and preparation of powder.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
