Description

Technical Field

[0001] This utility model relates to the field of sweet potato starch technology, specifically a sweet potato starch screening device. Background Technology

[0002] Sweet potato starch, also known as yam starch, sweet potato starch, sweet potato starch, yam starch, and mountain starch, can be made from two raw materials: fresh sweet potatoes and dried sweet potatoes. The process involves washing the sweet potatoes, cutting them into large pieces, mashing them into a paste, filtering, letting them stand, washing the sweet potato residue, and filtering again to finally obtain pure, additive-free sweet potato starch. Sweet potato starch is usually filtered using a sweet potato starch screening device.

[0003] Existing sweet potato starch screening devices place sweet potato starch on a filter screen and quickly filter it by shaking or vibrating to obtain sweet potato starch without impurities.

[0004] Existing sweet potato starch screening devices require manual removal of impurities left after filtration at regular intervals to prevent clogging of the filter and reduced screening efficiency. Manual removal of impurities also affects screening efficiency and increases the burden on operators. Therefore, we propose a sweet potato starch screening device. Utility Model Content
