Production line of sweet potato starch

Abstract

The invention discloses a production line of sweet potato starch. The production line comprises a drum washing machine, a sweet potato crusher, a residue and pulp separator, a potato residue dehydrator, a potato residue storage depot, a vacuum suction filter, an air current drying tower and a starch storage depot; a water inlet of the drum washing machine is communicated with a water outlet end of a filtering basin through a guide pipe; a water outlet of the drum washing machine is communicated with a water inlet end of the filtering basin through another guide pipe; a discharging end of the drum washing machine is connected with the sweet potato crusher through a conveyor belt; the sweet potato crusher is connected with the residue and pulp separator through a conveying pipeline; a potato residue outlet of the residue and pulp separator is connected with a feed opening of the potato residue dehydrator through the conveying pipeline; a discharge opening of the potato residue dehydrator is connected with a dryer through the conveyor belt. According to the production line disclosed by the invention, wastewater generated in a production process of starch is filtered and purified by arranging the filtering basin and a purifying pond, and clear water generated after purification is continuously used for production, so that the water consumption in the production process of starch is greatly reduced, and the production cost of enterprises is reduced.

Description

technical field [0001] The invention relates to the field of agricultural product processing and production equipment, in particular to a production line of sweet potato starch. Background technique [0002] The roots of sweet potatoes are not only rich in protein, starch, pectin, cellulose, amino acids and various minerals, but also there are many kinds of vitamins in sweet potatoes, such as carotene and vitamin B1. Sweet potatoes are not only nutritionally balanced, but also have little-known effects on preventing sub-health, weight loss, bodybuilding and anti-cancer. Scientific data shows that its calories are only 1 / 3 of that of rice, and because it is rich in cellulose and pectin, it has a special function of preventing sugar from turning into fat. At this stage, dietary fiber is becoming more and more important for modern people. Sweet potatoes in sweet potato starch contain a variety of nutrients needed by the human body. In particular, sweet potatoes are rich in l...

Problems solved by technology

[0003] The traditional sweet potato starch production line consumes a lot of water. Not only will a large amount of wastewater carrying sediment be generated in the cleaning process before sweet potato processing, but also a large amount of wastewater will be generated in the process of potato dregs dehydrator and starch slurry concentration. These The waste water has hardly been reused. If it is discharged directly, it will easily pollute the water source; in addition, in the traditional sweet potato starch production line, the potato dregs produced in the processing of sweet potatoes are simply dehydrated. If they are not dried, they will be stored directly. After long-term accumulation, it is prone to mildew and odor, which will affect the air quality nearby
