Common bottlenecks and solutions of cassava flour production

With the growth of market demand, the efficiency and stability of cassava flour production lines have become the focus. However, the production of cassava flour is fraught with several bottlenecks that impede production efficiency, product quality, and scalability. In this article, Henan Jinrui will provide a detailed analysis of common bottlenecks in cassava flour production lines, from raw material supply to cassava flour packing, and propose corresponding optimization solutions to improve the overall operational efficiency of the production line.

1. Bottlenecks and Solutions in the Raw Material Processing Stage

In the production of cassava flour, common bottlenecks in the raw material processing stage include raw material supply insufficient and incomplete cleaning. Insufficient raw material supply will lead to unstable production operation of cassava flour, while incomplete cassava cleaning will lead to poor quality of cassava flour products.

Cassava supply channel

1.1 Unstable supply of raw materials

- The seasonal supply of cassava raw materials leads to production fluctuations.

- Improper storage of raw materials can easily lead to mold growth or flour loss.

Solution:

- Establish a stable raw material supply chain, cooperate with planting bases, and ensure year-round supply

- Optimize warehouse management, adopt ventilated and dry storage methods, and add mold inhibitors if necessary.

1.2 Incomplete cleaning and impurity removal

- The impurities such as sediment and stones on the surface of cassava affect the subsequent crushing and flour extraction efficiency.

Solution:

- Adopting a multi-stage cleaning system in cassava flour production (such as dry sieve+paddle washer machine+high-pressure spray) to improve impurity removal efficiency.

- Add manual or automated sorting processes to ensure the cleanliness of raw materials.

2. Bottlenecks and Solutions in the Cassava Flour Processing Stage

After completing the cassava cleaning stage, the next stage is the cassava flour processing, including cassava peeling, grinding and dehydration, in which, poor peeling effect, low crushing rate and incomplete dehydration are the three common bottleneck problems in the cassava flour processing.

2.1 Poor peeling effect

- Peeling is a key step in cassava flour production. Poor peeling effect and low efficiency are a major problem in cassava flour processing.

Solution：

- Equipment the excellent peeling machine, such as Henan Jinrui's cassava peeler, which adopts sand roller peeling, up to 90% peeling rate, enhancing the efficiency and ensuring the quality.

2.2 Low grinding rate

- Traditional crushing equipment has high energy consumption and uneven particle size, which leads low crushing rate.

- The cassava cell wall was not fully damaged, resulting in incomplete release of the whole powder.

Solution:

- Adopt efficient hammer crusher or rasper, such as rasper designed by Henan Jinrui, optimize blade structure and speed, can achieve 98% crushing rate.

- Use of cutting machine and rasper together to fully destroy the cassava cell wall and improve the overall powder yield.

2.3 Incomplete dehydration

- The traditional filter press still has a high flour moisture content (>40%) after dehydration, which increases drying energy consumption.

Solution:

- Adopting a plate-frame filter press to improve dehydration efficiency.

3. Bottlenecks and Solutions in the Cassava Flour Drying Stage

Drying is a key step in cassava flour production and determines the quality of cassava flour. However, during the cassava flour drying process, bottleneck problems such as cassava flour gelatinization and low drying efficiency often occur.

3.1 Cassava flour gelatinization

- During the drying process, the cassava flour often becomes gelatinized due to the high moisture content of the dehydrated cassava flour or the high drying temperature.

Solution:

- Ensure that the moisture content of the cassava flour entering the drying equipment is below 40%, and control that the temperature of the drying equipment is not too high.

3.2 Low drying efficiency

- Traditional drying equipment has high energy consumption, poor drying effect and increased production costs.

Solution:

- Using the advanced drying equipment to improve thermal efficiency and avoid local overheating, such as flash dryer provided by Henan Jinrui, adopting a pulse tube design to increase the drying time and using negative-press drying to prevent powder loss.

4. Bottlenecks and Solutions in the Sieving and Packaging Stage

Uneven cassava flour particles (too coarse or too fine) and slow packaging speed are common bottlenecks encountered in the final stage of cassava flour production.

4.1 Uneven cassava flour particles

- During the sieving stage, if the mesh size of the sieving equipment is not appropriate or it is not equipped with a multi-stage screen, the cassava flour particles will be uneven.

Solution:

- Use multi-stage sieving equipment to screen cassava flour, such as Henan Jinrui's sifter, which is equipped with sieves of different mesh sizes. The processed cassava flour has uniform particles and meets the production standards of high-quality cassava flour.

4.2 Slow packaging speed

- Slow manual packaging speed, susceptibility to contamination, and inaccurate measurement.

Solution:

- Introduce automated packaging lines and use quantitative packaging machines to improve packaging speed and accuracy.

The efficiency and quality of cassava flour production line are affected by multiple links, from raw material processing to final packaging, each stage may become a bottleneck. By optimizing equipment selection, improving process parameters, enterprises can significantly improve the stability and production capacity of their production lines. In the future, with the application of automation and intelligent technology, cassava flour production will develop towards higher efficiency and energy conservation, further meeting market demand.
