Description

Technical Field

[0001] The utility model relates to the technical field of starch processing, in particular to a high-efficiency sand removal device for potato starch. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for food quality. Sweet potatoes are favored by people for their high nutritional value. In order to ensure that the products produced meet people's needs, the sweet potato processing industry is very important to remove the sand from sweet potato starch. The desanding of sweet potato starch refers to filtering out the ash in the sweet potato starch to obtain high-purity sweet potato starch. Most of the existing desanding processes use sweet potato starch desanders to remove the sand from the sweet potato starch suspension.

[0003] For example, the patent announcement number CN203625271U is a sweet potato starch sand removal device, which can add a sand collecting tank at the bottom of the cyclone tank to quickly discharge the heavy liquid containing sand and prevent it from flowing back, which is beneficial to improving the sand removal efficiency. The design is scientific and reasonable, the structure is simple, and the practicability is strong. By arranging a hollow partition above the feed port in the cyclone tank, the surrounding starch emulsion with high sand content is further reduced from being discharged from the discharge port, and the impurity content at the discharge port is further reduced.

[0004] The above-mentioned equipment adds a sand collecting tank at the bottom of the swirl tank to enable the sand-containing heavy liquid to be discharged quickly to prevent its backflow. By setting a hollow partition above the feed port in the swirl tank, the discharge of starch emulsion with high sand content in the surrounding area from the discharge port is further reduced. However, the process of the above-mentioned device is too reciprocating and complicated, and it is not convenient to clean the inside. For this reason, we propose a new type of potato starch high-efficiency sand removal device. Utility Model Content

[0029] A sand removal mechanism 7, arranged on the top of the base 4, is used to remove sand from potato starch;

[0030] The auxiliary mechanism 8 is arranged on the top of the top cover 6 and is used for fluidizing the transportation of potato starch.

[0031] The auxiliary mechanism 8 includes:

[0032] A storage box 801 is installed on one side of the top of the top cover 6, and a connecting pipe 802 is installed at one end of the storage box 801, a pump body 804 is installed at the other end of the connecting pipe 802, and a delivery pipe 803 is installed at one end of the pump body 804. The delivery pipe 803 penetrates the top cover 6 and extends to the inner side of the sealing plate 5, and the delivery pipe 803 is located above the sand removal mechanism 7.

[0033] like Figure 4 As shown, it should be noted that: starch is placed in the storage box 801 to fluidize the starch, and the fluidized starch in the storage box 801 is transferred to the inner side of the sand removal mechanism 7 via the connecting pipe 802 and the conveying pipe 803 by using the pump body 804.

[0034] The sand removal mechanism 7 comprises:

[0035] A fixing seat 721 is installed on the top of the base 4, and a trapezoidal slope 720 is arranged on the inner side of the fixing seat 721. A fixing frame is installed on one end of the trapezoidal slope 720, and a filter screen 719 is installed on the inner side of the fixing frame. A flow hopper 711 is installed on one end of the filter screen 719. A sealing sleeve 713 is connected to the output end of the flow hopper 711. The sealing sleeve 713 is located on the inner side of the sealing plate 5, and a discharge valve 712 is installed on the inner side of the sealing sleeve 713.
