Ratio of cassava to starch: How many tons of cassava can extract one-ton starch?

The ratio of cassava to starch has always been a concern for cassava processors. Theoretically, the cassava to starch ratio is 4:1, meaning that 4 tons of fresh cassava can extraction one ton of starch. However, this is only achievable under ideal conditions. In reality, starch extraction yield is often affected by a variety of factors, such as raw material quality and processing equipment.

Henan Jinrui Food Company, as the professional starch equipment manufacturer, will provide a detailed analysis of the factors influencing starch extraction yield and provide comprehensive guidance on maximizing cassava starch extraction yield.

Factors Affecting Starch Extraction Yield

1.Cassava Varieties: Different cassava varieties have significant differences in starch content. Generally speaking, high-quality edible or industrial cassava varieties have relatively high starch contents, typically between 20% and 30%. For example, some improved high-starch cassava varieties can reach starch contents exceeding 25%. This means that when using these cassava varieties for starch extraction, approximately 4 tons of cassava are required to extract 1 ton starch. In contrast, some wild or low-yielding cassava varieties may only have a starch content of around 15%, naturally requiring more cassava raw material to extract 1 ton of starch.

2. Starch Processing Technology: The starch processing technology significantly impacts the extraction rate of cassava starch. Traditional cassava starch processing, using sedimentation tanks, results in a starch loss rate of 15% to 20%, requiring a significant amount of raw cassava to extract one ton of starch. Modern cassava processing, using multi-stage hydrocyclone plus centrifugal dehydration technology, achieves a starch extraction rate of up to 92%, reducing the amount of cassava required to extract one ton of starch, and the resulting cassava starch is of higher quality.

3.Processing Equipment Selection: Choosing efficient starch processing equipment can also improve starch extraction rates. Grinding and purification equipment have a significant impact on starch extraction efficiency. For example, a Nigerian customer using a hammer mill required 5-6 tons of cassava to produce one ton of starch, while using Henan Jinrui's rasper only required 4 tons. This is mainly because the rasper can achieve a cassava crushing rate of up to 98%, maximizing starch release. Similarly, choosing an advanced horizontal centrifuge sieve (1,200 rpm) for starch extraction is more effective than a vertical sieve (600-800 rpm) in separating fibers, minimizing starch loss in the residue (residual starch 0.2%), and improving starch extraction rates, which means that less cassava can be needed to process one ton of starch.

Guidance for Maximizing Cassava Starch Extraction Rate

After learning the factors that influence starch extraction, here is the guidance for maximizing cassava starch extraction, reducing the amount of cassava raw material needed to extract 1 ton of starch, and maximizing your starch processing business profits:

- Using right cassava variety: Choose cassava varieties with high starch content. The best variety is cassava with 25% starch content. Only 4 tons of this variety of cassava are needed to process 1 ton of starch.

- Fully grinding: Using grinding equipment with a high crushing rate, such as Henan Jinrui's rasper, with the cassava crushing rate of 98%, and can fully release the starch, which means that less cassava is needed to process 1 ton of starch.

- Optimize extraction technology: Use advanced cassava starch purification equipment, such as Henan Jinrui's bedroom centrifuge sieve and 18-stage hydrocyclone stations, which adopt innovative design to reduce starch loss while separating fiber, protein and other impurities, thereby improving starch extraction rate.

- Water Recycling: Countercurrent washing in paddle washers and centrifuges recycles water, reducing waste and improving starch extraction yield.

In summary, under ideal conditions, using a high-starch cassava variety (25% starch content) and advanced processing technology (90% extraction yield), approximately 4 tons of cassava are required to extract 1 ton of starch. However, the cassava to starch yield ratio is affected by various factors. In actual production, choosing high-quality varieties, improving processing technology, and selecting efficient processing equipment can effectively increase starch extraction yield, reduce raw material consumption, and thus improve production efficiency.
