Abstract

The invention discloses a sweet potato starch production method. The sweet potato starch production method comprises the following specific steps: sweet potatoes are cleaned, specifically, the sweet potatoes are placed into a cleaning machine to be cleaned for 1-2 hours; crushing and jordaning are conducted, specifically, dried sweet potatoes are smashed, clear water is added according to the massratio of feed liquid, after even stirring, a certain quantity of lime milk solution is added, and soaking is conducted; slurry residue is separated, specifically, grinding is conducted after soaking,and starch milk is obtained through sieving; starch is extracted, specifically, the starch milk is divided into ten equal parts and placed into a centrifugal machine in batches to be separated, upper-layer waste liquid is removed after centrifugation, and the starch is obtained. According to the sweet potato starch production method, the water using amount can be significantly decreased, meanwhile, the starch yield can be increased, and waste of the sweet potatoes is avoided.

Description

technical field

[0001] The invention relates to the technical field of sweet potato starch processing, in particular to a production method of sweet potato starch. Background technique

[0002] Sweet potatoes are widely grown in China, from Hainan Province in the south to Heilongjiang in the north, and to the mountainous areas in western Sichuan and the Yunnan-Guizhou Plateau in the west. dietary fiber etc. Carotene, vitamin B1 and other vitamins in sweet potatoes are necessary for maintaining human health.

[0003] Sweet potato starch is one of the main products of sweet potato processing. Sweet potato starch can be divided into two types: fresh sweet potato and dried sweet potato. However, since the quality of fresh sweet potato starch is better than that of dried sweet potato, most starch processed from fresh potato is used. When the existing sweet potato starch is processed, the yield of starch is relatively low, and the sweet potato is relatively wasted. For this reas...

Examples

Embodiment 1

[0041] Such as figure 1 Shown, a kind of sweet potato starch production method, described concrete steps are as follows:

[0042] (1), sweet potato cleaning: put the sweet potato in the washing machine to clean for 2 hours;

[0043] (2), crushing and refining: crush the dried potato, and add clear water according to the mass ratio of material to liquid, after stirring evenly, add a certain amount of lime milk solution for soaking;

[0044] (3), pulp and residue separation: grind after soaking, and sieve to obtain starch milk;

[0045] (4) Starch extraction: Ten equal portions of starch milk are placed in a centrifuge for separation in batches, and the upper layer waste liquid is removed after centrifugation to obtain starch.

[0046] The washing machine in the step (1) is a paddle washing machine.

[0047] In the step (2), after the dried potato is crushed, it is added into clean water according to the mass ratio of solid to liquid, and the mass ratio of solid to liquid is ...
