Potato Starch Vibrating Screen

What is a Potato Starch Vibrating Screen?

Potato starch vibrating screen are used in key stages of starch processing, including extraction, fine residue screening, pulp screening, and sand and impurity removal, separating fibers, potato residue, and fine particles. Commonly used equipment includes 60-mesh, 80-mesh, and 100-mesh stainless steel screens with 1-5 layers and diameters of 1000mm or 1500mm. The sieved starch is then packaged. The screening area is typically around 0.5–3㎡, with a production capacity of approximately 2–3.5 tons/hour.

Potato starch vibrating screens can screen potato starch, corn starch, wheat starch, cellulose, soybean starch, peanut protein, flour, cassava starch, and other starch raw materials and their derivatives. They are used to remove impurities and lumps from potato starch and also have the function of loosening materials.

What are the advantages of a Potato Starch Vibrating Screen?

The Potato Starch Vibrating Screen is made of 304 stainless steel. The cleaning and sealing devices use silicone balls and silicone rings, respectively, which meet the hygiene standards of the food industry. The movement of the bouncing ball and other net cleaning devices has a high penetration rate on the net surface, which is conducive to removing potato starch residue from the net surface. It has good airtightness, no dust splashing, and ensures a clean operating environment. The air outlet can be adjusted 360 degrees for easy connection to the field.

Technical parameters of potato starch vibrating screen

What are the working principles of a Potato Starch Vibrating Screen?

Potato starch vibrating screen uses the YZUL vertical vibration motor as the excitation source, and uses the eccentric weights at the upper and lower ends of the vibration motor to convert the rotary motion into a horizontal, vertical, and inclined three-dimensional motion, which is transmitted to the screen surface of the rotary vibrating screen; The material enters the equipment through the inlet. According to different material screening requirements, the material passes through the sieve of the sieve for layering. In this process, the bouncing ball, a cleaning device located under the sieve, continuously hits the sieve, causing the sieve to be layered. The material can be screened through the mesh smoothly and effectively solves the problem of material blockage. The over-screen material and under-screen material are discharged from different outlets , so as to achieve the purpose of screening and removing impurities or filtering and grading.

Recommended mesh number of potato starch vibrating screen

What is the applicable material range of the potato starch vibrating screen?

Core applicable materials

Starch

Root starch (potato starch, cassava starch, sweet potato starch, taro starch) has coarse particles (15-100μm) and needs to be graded to remove fibers and impurities.

Cereal starch (corn starch, wheat starch, rice starch) has finer particle size (5-50μm) and requires a high mesh screen (200 mesh or more).

Modified starch (hydroxypropyl starch, acetate starch, etc., need anti-sticking screening)

Food powder

Edible powder (impurity removal or classification of dry powders such as flour, rice flour, bean flour, lotus root powder, etc.)

Seasoning (screening of powdered sugar, monosodium glutamate, yeast powder, moisture-proof design is required)

Industrial powder

Soluble powder (cellulose powder, plant protein powder) (easy to absorb moisture, need closed screening)

Inorganic powder (talcum powder, diatomaceous earth) (particle size close to starch, can share equipment)

Unsuitable/cautious materials

What is the purpose of a potato starch vibrating screen?

A potato starch vibrating screen is used in starch processing to screen, filter, and remove impurities such as fibers and sand from starch slurry or dry starch, resulting in uniform and high-purity finished starch granules. In the initial screening of starch slurry, it separates the ground starch slurry from potato fibers, ensuring the initial purity of the starch. During multiple refining and washing processes, the vibrating screen grades the starch slurry through screens of different mesh sizes, removing residual fine fibers and impurities, improving the whiteness and fineness of the starch. In the dehydrated dry starch stage, it can also be used to screen the finished starch, ensuring uniform starch granules that meet the fineness requirements of different customers for potato starch.

How to fix a potato starch vibrating screen?

Check the screen for damage or looseness and replace it promptly. Check the motor for smooth operation, abnormal noise, or overheating. Check the springs for breakage or deformation, which could affect vibration performance. Inspect the screws; after prolonged use, the vibration screen bolts may loosen and need to be tightened periodically. Replace the grease every 6 months to prevent bearing wear. If the motor overheats abnormally or the vibration intensity weakens, the coil may be damaged and needs replacement or repair. If the screen needs to be replaced, first turn off the power to ensure equipment safety. Remove the screws securing the screen frame, remove the old screen, install the new screen, and tighten it to prevent loosening. Check the sealing strip to prevent dust leakage.
