The Application of Vibrating Screen in Food Industry

Vibrating screen is a highly efficient screening machinery used in food industry. It’s mainly used for high precision fine powder and other materials with its advantage of easy operation and fully enclosed structure.

It is also suitable for granular, powder, mucus and other materials screening and filtering classification，Such as powdered sugar, starch, salt, rice flour, milk powder, milk, egg, soy sauce, vinegar, fruit juice, papaya powder, green tea powder, kudzu powder, and potato processing production. Materials mentioned above are used frequently in daily life, vibrating screen will be our best assistant.

Take Starch or rice powder for example, In the first step, we usually remove the impurity of raw materials followed by screening and weighing; The next step includes soaking, coarse grinding, germ separation, fine grinding, screening of starch, protein separation, centrifugal dewatering and thermostatic drying, The last step includes weighing and product packing.

During these steps, we will have great difficulty in processing the food without the screening of vibrating screen. Vibrating screen has the superiority in easily screening fine material, and therefore bring us the food diversification and help to develop the entire food industry rapidly.

Introduction of Dewatering Screen

Have you felt very confused with wet materials put in the bag or other places?Today our dewatering screen will help you!
Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.
 

dewatering screen

To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.

linear vibrating screen

► Introduction
Linear vibrating screen is designed with dual-vibration motor drive.Two synchronous motors are reversely placed so that the exciter generate reverse excitation force, the exciting force generated by eccentric block cancel each other out on the parallel direction of motor axis,and stack together with the perpendicular direction of motor axis, so its trajectory is linear.Linear vibrating screen is suitable for particle size from 0.074 -5 mm,the maximum size should be less than 10mm.

► Application:
Linear vibrating sieve is widely used in mining, coal, refractories, metallurgy, building materials and other industries. Mineral linear vibrating screen is usually used for the screening and grading materials in large, middle and small particles.

► Introduction and working principle：
Rotary vibrating screen is designed as a high-precision screening machinery. Round vibrating sieve is composed of vertical motor,and eccentric weight installed at two ends.We can produce horizontal, vertical, inclined motions by adjusting the upper and lower eccentric weight.Diameter can be ranged from 400mm to 2000mm, with single or multiple screening decks.
► Working Principle：

XZ Rotary Vibrating Screen is a vertical-motor system, with eccentric hammers being installed on top and bottom of the machine, where the motor acts as the vibratory source. The direction of the eccentric hammers may change its rotational mode either in horizontal, vertical and inclined movement onto the sieving screener surface. The trajectories of the materials on the sieving machine can be change by adjusting the phase angle on both top and bottom parts.
