Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 Shown in, a kind of processing method that fresh sweet potato produces high-quality starch comprises the steps:

[0020] (1) Remove the root hairs, insect eyes and black spots on the surface of the potato, then cut off the rotten part of the wound with a knife, and then put it in water for stirring and cleaning to remove the soil and impurities on the surface to obtain a clean potato;

[0021] (2) Put the clean sweet potato into the grinder, process and grind the sweet potato into fine fiber flocs, flow out from the discharge port of the grinder, and then collect;

[0022] (3) Put the collected potato fiber floc into clear water 8-10 times higher, stir and mix into a thick liquid to free the fine fibers in clear water, then pour it into a 140-180 mesh vibrating screen for deslagging Filter to remove slag, and wait until the potato flocs are re...

Abstract

The invention discloses a method for producing high-quality starch from fresh sweet potatoes. The method comprises cleaning for impurity removal, mechanical grinding, uniform stirring with water, mechanical vibration for filtering sweet potato fiber floccules, water removal and oil powder layer scraping after precipitation, beating molding, drying and crushing for preparation of powdery sweet potato starch. The method is simple, is easy to operate, realizes efficient, fast and clean slag removal based on a slag removal vibrating screen, and prevents sweet potato fibers in the filtrate. After precipitation, the oil powder layer is scraped. The starch is clean, bright and white and has no other color. Through slag removal vibrating screen-based filtration, the starch in the sweet potato flocculent fibers are thoroughly released, a yield is high and sweet potato weight is light.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a processing method for producing high-quality starch from fresh sweet potatoes. Background technique [0002] At present, in the production and processing industry of edible sweet potato starch in my country, due to the lack of national standards to regulate, the industry standards implemented by different enterprises are not the same, resulting in large differences in the quality of starch and uneven product quality. In recent years, some unscrupulous traders have adulterated and faked products for their own benefit, shoddy and shoddy products, endangering the interests of consumers. [0003] Sweet potato starch is processed from sweet potatoes and is of poor quality. The color is dark, the texture is rough, the viscosity is poor, but the swelling is strong. Sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, and sweet potato. It is no...
