How to use YAM to produce YAM starch?
YAM has high starch content, and fresh YAM tubers are one of the best raw materials for starch production. Aware of this fact, the African government has begun to restrict starch imports in recent years and encourage factories to produce starch from YAM tubers to meet high demand and reduce YAM waste. Therefore, more and more people are interested in YAM starch business and Want to know how YAM produces starch? if you
There is still this problem, please read this article.
Starch processing is actually a physical extraction process. Generally, it is divided into three parts: raw material cleaning, starch extraction and refining, dehydration and drying.
First, we need to remove impurities from YAM's raw tubers. Here we mainly use two steps-dry cleaning and wet cleaning.
YAM raw materials will first enter the dry sieve, and impurities such as sand, weeds, stones, etc. mixed with the harvested YAM tubers will be removed. These impurities will fall through the gaps between the machines and be discharged regularly. After that, the cleaned YAM will be transferred to the paddle washing machine for deep cleaning. Under the action of paddle agitation and countercurrent washing principle, the other on YAM
Attachments such as sand and soil are thoroughly washed.
After cleaning the part, we need to extract starch and separate out non-starch impurities to obtain pure starch.
To extract starch, we need to crush YAM into pulp to release starch. As YAM roots are long and large, we usually cut YAM into small pieces and crush them. Then distribute the YAM block to the wood grinder. Rasper is currently the most advanced crusher, it can fully destroy YAM cells to ensure maximum release of starch. A sharpener can achieve a fracture rate of over 94%.
After crushing, we can get YAM, which contains starch and other impurities, such as fiber, protein, fat, etc. If you want to get purified starch, you need to remove them all at once. The separation process can be divided into two parts: centrifugal sieve and fine fiber sieve to separate fibers and fine fibers. Equipped with disc separator and hydrocyclone to remove protein and other liquid impurities
. After these steps, we can finally get high-quality purified starch slurry.
In the starch extraction part, coarse grinding is a key equipment that directly affects starch production. Our files have a high crushing rate and efficiency. If the starch content of YAM tubers is not less than 23%, we can ensure that every 4 tons of tubers can produce 1 ton of starch as a finished product.
Finally, we need to dehydrate and dry YAM starch to obtain dry edible starch.
In this section, we need to dehydrate the pure starch milk first to obtain wet starch with a moisture content of 38-40%. The wet starch is then sent to a rapid dryer to obtain dried starch with a moisture content of about 12%. The dehydrator we use here is a peeler centrifuge, which has a high speed, so it can separate water more thoroughly. In the drying process, in order to reduce
For starch loss and clean working environment, our flash dryer adopts negative pressure design. In addition, all parts in contact with materials are made of food grade stainless steel.
