Introduction of potato starch vibrating screen

Potato starch vibrating screen is a screening equipment specially designed for potato starch, corn starch, wheat starch, cellulose, soybean, peanut protein, flour, tapioca starch and other starch materials and derivatives of starch materials. It is used to remove impurities and agglomeration in potato starch, and also has the function of loose material.

Potato starch vibrating screen commonly used 60 mesh, 80 mesh, 100 mesh stainless steel screen with a diameter of 1000mm or 1500mm, single layer. Screen starch before packaging. The production capacity is about 2-3.5 tons/hour.

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

Material type	reason	alternative solution
High viscosity slurry (such as sauce)	easy to block the screen, poor fluidity	centrifugal screen or filter press
Highly corrosive chemicals	damaged stainless steel screen	plastic material vibrating screen
High temperature materials (＞80℃)	affect the life of seals	screening after cooling or high temperature resistant equipment
Slag with fiber content ＞30%	need to be pre-treated by centrifugation or coarse screening	screw extrusion screen + vibrating screen combination

Benefits of potato starch vibrating screen

1. It adopts 304 stainless steel, and the cleaning device and sealing device adopt silica gel ball and silica gel ring respectively, which meets the hygiene standards of the food industry.

2. The movement of the net cleaning device such as the bouncing ball, the screen has a high penetration rate, which is beneficial to clean up the residual materials on the screen.

3. Good airtightness, no dust flying, ensuring the cleanliness of the operating environment.

4. The discharging port can be adjusted 360 degrees arbitrarily, which is convenient to connect with the scene.

Working principle of 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

Screening purpose	Recommended mesh number (mesh)	Function description
Primary screening (impurity removal)	10-40 mesh	Remove large particle impurities, fibers, and uncrushed lumps
Fine screening (finished product grading)	80-120 mesh	Increase starch fineness, remove coarse particles, and ensure uniformity
Ultrafine screening (high purity requirements)	150-200 mesh	Improve starch quality to meet the needs of high-end food, pharmaceuticals, etc.
Starch slurry filtration	200-300 mesh	Filter fine impurities in starch slurry to improve extraction rate

What is the purpose of a potato starch vibrating screen?

Potato starch vibrating screen can be used for screening, impurity removal, loose materials, etc. It is suitable for 24 hours continuous production and large processing capacity. In addition, it is also suitable for wheat starch, corn starch, tapioca starch, sweet potato starch, potato starch, starch derivatives, cellulose, soy protein powder, peanut protein powder, flour, PVC powder, steel grit and other powders.

How to fix a potato starch vibrating screen?

Daily inspection

Check the screen (whether it is damaged or loose, and replace it in time); check the motor (whether it runs smoothly, whether there is any abnormal noise or overheating); check the spring (whether it is broken or deformed, affecting the vibration effect); check the screws (after long-term use, the vibration screen bolts may loosen and need to be tightened regularly).

Motor maintenance

Replace the grease every 6 months to avoid bearing wear.

If the motor is abnormally hot or the vibration intensity becomes weak, it may be that the coil is damaged and needs to be replaced or repaired.

Screen replacement: Turn off the power, ensure the safety of the equipment, remove the screws that fix the mesh frame, remove the old screen, install the new screen, tighten and fix it to prevent loosening, check the sealing strip to avoid dust leakage.
