Precautions for operating the sweet potato starch production line

Sweet potatoes have a high content of lysine, which is relatively lacking in cereal foods, and are rich in vitamins, and starch is also easily absorbed by the human body. As a result, the sweet potato starch production line has also been favored by consumers, but many manufacturers are not clear about the specific operation of the high-quality and durable sweet potato starch production line, so this article specifically introduces the precautions for operating the sweet potato starch production line:

Precaution 1: Purification of fresh potatoes

Usually, the sweet potato starch production line adopts wet washing, that is, fresh potatoes are added to the washing conveyor for water washing. Since the potato pieces after the initial washing may be mixed with a small amount of fine sand, the rotating cage is designed as a grid structure, so that the potato pieces roll, rub, and wash in the cage, while the small pieces of sand and gravel are discharged from the gaps of the rotating cage, thereby achieving the effect of cleaning and removing sand and gravel.

Precaution 2: Fine grinding

The purpose of fine grinding in the sweet potato starch production line is to destroy the cells of fresh potatoes and free the starch particles in the cell wall so as to separate them from fibers and proteins. In order to further increase the starch free rate, the sweet potato starch production line needs to be finely ground, and the grinding should not be too fine, which can reduce the difficulty of fiber separation.

Note 3: Separation of fibers and proteins

Fiber separation adopts the screening method, commonly used vibrating flat screen, rotary screen and conical centrifugal screen, pressure curved screen, in order to make the free starch fully recovered, generally two or more screenings are used to make the free starch in the fiber residue reach the specified value on dry basis. Before separating protein, it is necessary to use cyclone desanders and other sand removal to purify starch.

Note 4: Storage of powder milk

Due to the short processing period of fresh potatoes, the sweet potato starch production line of the factory usually concentrates the crushing and processing of fresh potatoes, stores the starch milk in multiple storage tanks, seals after the starch precipitates, and then slowly dehydrates and dries. And it should be noted that the pH of the powder milk should be adjusted to a neutral range or other preservatives should be added before the sweet potato starch production line is stored.

Pay attention to the relevant information of the direct sales of the sweet potato starch production line manufacturer, which will help consumers better choose the sweet potato starch production line.
