Same starch processing, why can 50kg of sweet potatoes produce 1.5kg of starch? There are basically three points: choosing the right variety, harvesting at the right time, and selecting the right equipment.
Choosing the Right Sweet Potatoes Is Essential for Starch Processing
Although they are all called sweet potatoes, there are different types of sweet potatoes.They can be classified based on their function: edible, feed, and starch, and based on their color: red, yellow, purple, and white.
The growth cycle, taste, appearance, sugar content, and starch content vary greatly. Therefore, there are certain considerations when choosing which type of sweet potato to process starch from.
The first choice is white sweet potatoes used specifically for processing starch, with a high starch content between22%-26%.
Harvesting Sweet Potatoes During Frost Season Is Perfect for Starch Processing
When to harvest sweet potatoes is also a skill. They should not only be harvested in a timely manner but also processed as soon as possible, without long-term storage. The longer sweet potatoes are stored, the sweeter they become. This results in more sugar conversion and less starch content, which leads to lower starch extraction rate.
Digging them out right after the first frost and delivering them to the starch processing factory immediately ensures good starch quality and high extraction rate.
New Overflow Elutriation Crushers Perfect for Starch Processing
This type of overflow elutriation crushers spiked rollers, 2 sieves, secondary rotating blades for thorough and delicate grinding. It also employs dual-stage sieving and thorough washing, resulting in low loss and high filtration rate.
Sending in 50kg of sweet potatoes can produce 1.5kg of starch. However, using a poorly functioning overflow elutriation crushers can result in wasting 2.5kg of starch when sending in 50kg of sweet potatoes.
