Description
Technical field
The present invention relates to starch processing technique field, in particular to a kind of processing method of starch from sweet potato.
Background technique
Sweet potato is that the important low investment in China, high production, drought-resistant, resistance to lean book, multipurpose i.e. grain, feed and industry are former
Expect crop.Sweet potato nutrient is abundant, removes and contains much starch, Vc, VB1, VB2, VE, carrotene, dietary fibre and a variety of amino acid
(especially lysine rare in rice and flour is very abundant) outside, also containing minerals such as calcium, phosphorus, iron, potassium, and has anti-cancer, anticancer
The substances such as mucus protein, dehydrobenzene, quasi- female sex hormone and the selenium of effect.Sweet potato nutrient balances, is complete, and nutritive value is not low
In rice, face, fresh sweet potato eats the status in structure in people and draws attention again.In recent years, China's starch industry achieved length
Foot development, especially supply falls short of demand for starch from sweet potato.
In the prior art, the process flow of starch from sweet potato processing technology are as follows: raw material selection → cleaning → size degradation → screening →
It removes sand → precipitates (or concentration) → dehydration → drying → air-cooled packaging, production technology production efficiency is low, and product quality is relatively less
Stablize, and a large amount of water source can be wasted in process, and the discharge for generating waste water and waste residue can cause one to environment
Fixed pollution constitutes certain threat to ecological environment.For this purpose, it is proposed that a kind of processing method of starch from sweet potato.
Summary of the invention
The main purpose of the present invention is to provide a kind of processing methods of starch from sweet potato, can effectively solve in background technique
The problem of.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of processing method of starch from sweet potato, comprising the following steps:
(1), the high new fresh sweet potatoes of the white flesh of red skin of good content of starch are chosen, sweet potato is immersed in clear water, when immersion
Between be 20-30 minutes, after the mud gravel on sweet potato surface is loose, is cleaned up, drained away the water with hairbrush, it is standby to obtain clean sweet potato
With；
(2), the sweet potato cleaned up addition fiberizer is crushed, refining process processing, obtains sweet potato paste, controls defibrination
Granularity be 20-50 mesh, sweet potato paste obtained and water are mixed to uniformly by 1:2.5-3.5, it is spare to obtain sweet potato slurries；
(3), sweet potato slurries made from step (2) are subjected to first time filtering by 50-60 mesh filter screen, by first time mistake
It filters resulting filtrate and second of filtering is carried out by 90-100 mesh filter screen, the oversize filtered twice is collected, and is added to
Step (2) carries out second-time breakage, refining process processing；
(4), second of resulting filtrate of step (3) is sent into sedimentation basin and carries out depositing technology processing, the filtrate after precipitating
It can be separated into upper, middle and lower-ranking, upper layer is supernatant layer, and middle layer is stratum granulosum, and lower layer is waste residue layer, and supernatant layer is filtered out return
Abovementioned steps, for sweet potato immersion, cleaning and preparation sweet potato slurries, by stratum granulosum carry out dewatered drying both starch at
Product become irrigation water, precipitating silt after waste water, waste residue, silt that waste residue and step (1) generate to be passed through to the fermentation process of wastewater disposal basin
Mud returns field use.
Compared with prior art, the invention has the following beneficial effects: the present invention overcomes conventionally produced low efficiency,
The shortcomings that unstable product quality, and being recycled with water to starch process, reduce processing cost, avoid pair
It is polluted caused by environment.
