Advantages of centrifugal sieve in starch processing

Centrifugal Sieve, also known as horizontal centrifugal Sieve, is a common equipment in the field of starch processing. Its main function is to separate pulp residue. It can be used in the processing of various starch raw materials such as corn, wheat, potato, cassava, banana taro, kudzu root, arrowroot, Panax notoginseng, etc. Compared with other ordinary starch pulp and residue separators, centrifugal Sieve has the advantages of high Sieveing efficiency, good effect and large processing capacity in the starch processing process.

Starch centrifugal Sieve mainly relies on centrifugal force to work. In the starch processing process, the raw material slurry formed by crushing raw materials such as sweet potatoes and potatoes is pumped into the bottom of the centrifugal Sieve by a pump. The Sieve basket in the centrifugal Sieve rotates at high speed, and the Sieve basket speed can reach more than 1200 rpm. When the starch slurry enters the surface of the Sieve basket, due to the different sizes and specific gravity of impurities and starch particles, under the combined action of the strong centrifugal force and gravity generated by high-speed rotation, the fiber impurities and fine starch particles enter different pipes respectively, thereby achieving the purpose of efficient separation of starch and impurities. This working principle based on centrifugal force enables the centrifugal Sieve to achieve separation more quickly and accurately when processing starch slurry.

Advantage 1: High efficiency in starch and fiber Sieveing
Centrifugal Sieve have obvious advantages in Sieveing and separation efficiency. The centrifugal Sieve separates starch particles and fiber impurities in starch slurry through the strong centrifugal force generated by high-speed rotation. Compared with the traditional hanging cloth extrusion pulp-residue separation, the centrifugal Sieve can achieve continuous operation without frequent shutdown. In large-scale starch processing and production, the centrifugal Sieve can work continuously and efficiently, greatly improving production efficiency. For example, in some large starch processing plants, centrifugal Sieve are used for pulp-residue separation, which can process a large amount of starch slurry per hour, which is several times the processing capacity of ordinary separators, greatly meeting the company's requirements for production efficiency.

Advantage 2: Better Sieveing effect
The Sieveing effect of the centrifugal Sieve is excellent. In the starch Sieveing process, 4-5-stage centrifugal Sieve are usually equipped. The raw material slurry is filtered by multi-stage centrifugal Sieve to effectively remove fiber impurities in the starch slurry. At the same time, some centrifugal Sieve are equipped with automatic control systems, which can realize automatic feeding and automatic slag discharge to ensure the stability of the starch Sieveing effect. Through multi-stage Sieveing and precise centrifugal force control, the centrifugal Sieve can reduce the impurity content in starch to an extremely low level, and the starch produced is of high purity and excellent quality, which can meet the needs of industries with high requirements for starch quality such as food and pharmaceuticals.

Advantage 3: Improve starch yield
The starch Sieveing process is one of the key links affecting starch yield. Centrifugal Sieve play a key role in reducing starch loss and increasing starch yield. Starch centrifugal Sieve are generally equipped with four or five-stage centrifugal Sieve. The mesh surface of each Sieve basket uses meshes of different finenesses of 80μm, 100μm, 100μm, and 120μm. The fibers Sieveed out at each level need to enter the next level for re-Sieveing. Clean water is added to the last level of the centrifugal Sieve to form a countercurrent washing to reduce the loss of starch in the potato residue, thereby achieving a better Sieveing effect. The starch centrifugal Sieve produced by Jinrui can control the starch content in the potato residue below 0.2%, minimize the starch loss rate, and increase the starch yield.

Advantage 4: High degree of automation, suitable for large-scale starch production
Centrifugal Sieve are more suitable for large-scale and automated production needs. It can realize continuous feeding and continuous discharging, and is convenient to connect with other starch processing equipment to form an automated production line. During the entire production process, only a small amount of manpower is required for monitoring and maintenance, which greatly reduces labor costs and improves the stability and continuity of production. For example, in a modern starch production workshop, the centrifugal Sieve can work in conjunction with crushers, pulpers, desanders and other equipment to form an efficient automated production line.
