High Water Consumption in Cassava Starch Processing, Centrifugal Sieve Empowers Water-Saving Starch Extraction

In the industrial production of cassava starch, the water washing and starch-fiber separation section is the core link of water resource consumption, and also a common operational pain point for large and medium-sized starch processing plants. The inefficient design of traditional separation equipment exacerbates this problem, and the Centrifugal Sieve, a special separation equipment for starch processing, is optimized in process and structure precisely for this pain point. Traditional separation equipment mostly adopts the forward flow washing mode. To ensure the starch extraction rate, a large amount of clean water needs to be continuously injected to complete the slurry washing, which not only increases the water resource cost in production, but also raises the process pressure of subsequent wastewater treatment, running counter to the green and water-saving production requirements of the food processing industry in the overseas market.

At the same time, the fiber characteristics of cassava raw materials determine that the water washing efficiency of the separation link directly affects the quality of starch milk. If water consumption is simply reduced, the problem of incomplete separation of starch and fiber is prone to occur, leading to a decline in starch extraction rate. This forms an industry dilemma of "it is difficult to balance water saving and efficiency improvement". The Centrifugal Sieve adapted to cassava starch processing is the core equipment to solve this dilemma and the key solution to restrict the cost reduction and efficiency improvement of cassava starch processing enterprises.

Aiming at the water consumption pain point in cassava starch processing, the special Centrifugal Sieve for starch processing has become the mainstream water-saving solution in the industry by virtue of its counter current washing and separation process, and is also the core selection equipment in the cassava starch production line. Designed exclusively for the separation of cassava starch slurry, the equipment is adapted to the starch milk treatment process after rasping and desanding, achieving the dual goals of water saving and high-efficiency separation from the aspects of process design and structural configuration, and is the preferred separation equipment for overseas cassava starch processing plants at present.

The Centrifugal Sieve adopts a multi-layer composite screen made of all stainless steel, and cooperates with the centrifugal separation principle of the rotating sieve basket, allowing the starch milk to complete fine separation under the action of centrifugal force. The counter current washing mode makes clean water and slurry flow in the opposite direction, maximizing the utilization efficiency of water resources, and the effective separation of fiber and starch can be completed without a large amount of water supplement. Meanwhile, the dead-corner-free structural design of the Centrifugal Sieve avoids slurry residue, which not only meets the food hygiene production standards, but also reduces the additional water consumption caused by residue cleaning, further achieving water-saving effects from the structural end.

In the equipment selection of cassava starch processing plants, to achieve a stable water-saving effect through the Centrifugal Sieve, it is necessary to focus on the process adaptability and structural design of the equipment, which are also the core points in the Centrifugal Sieve selection guide. First of all, it is necessary to confirm whether the Centrifugal Sieve is equipped with a counter current washing system, which is the core process to achieve water saving and a key design different from traditional forward flow washing equipment. Secondly, attention should be paid to the matching degree between the processing capacity of the Centrifugal Sieve and its own power, to ensure that the equipment can not only adapt to the industrial production needs of the production line under the continuous working mode, but also avoid energy waste caused by excessive power.

In addition, the material and separation accuracy of the Centrifugal Sieve also directly affect the water-saving effect. The Centrifugal Sieve with food-grade stainless steel for parts in contact with materials can reduce slurry wall hanging and residue, and lower the cleaning frequency and water consumption. The implementation of this special Centrifugal Sieve in cassava starch processing enables enterprises to greatly reduce the water consumption in the washing link on the premise of ensuring the starch extraction rate, and simplify the production process without additional configuration of transfer storage tanks. It realizes water-saving starch extraction from the process end, adapting to the green production trend and cost reduction demand of the overseas cassava starch processing industry.
