Glutinous rice flour food industry vibrating screen

Glutinous rice flour has the characteristics of strong viscosity, easy agglomeration and fine particles, which makes it easy to have problems such as clogging and low screening efficiency during food processing and screening. The glutinous rice flour food industry vibrating screen is a special screening equipment designed for the characteristics of glutinous rice flour. It usually adopts a multi-layer design (commonly 2 to 4 layers) and is equipped with an appropriate mesh number (generally between 80 and 200 meshes) to achieve coarse and fine classification, impurity removal and particle size homogenization. The equipment disperses the glutinous rice flour evenly through high-frequency vibrating, effectively removes impurities, coarse particles or lumps, ensures the purity and consistency of the powder, and improves the quality and efficiency of subsequent processing such as steaming and molding.

How to choose a glutinous rice flour food industry vibrating screen?

When choosing a glutinous rice flour food industry vibrating screen, it is necessary to comprehensively consider factors such as the physical properties of glutinous rice flour, screening accuracy, processing capacity, production line requirements and hygiene standards. The following are detailed suggestions:

Glutinous rice flour has the characteristics of being delicate, easy to absorb moisture, and easy to agglomerate, and the swing screen is more suitable for its screening needs. The swing screen can classify glutinous rice flour more gently and effectively through low-frequency, three-dimensional swinging motion, is not easy to block the net, has high screening efficiency, and has little effect on the powder structure, which meets the comprehensive requirements of food safety, quality and production capacity. If the screening accuracy is not high and the processing volume is small, you can also choose a more cost-effective rotary vibrating screen, but in most industrial glutinous rice flour processing scenarios, the swing screen is a better choice.

Working principle of glutinous rice flour food industry vibrating screen

The working principle of the glutinous rice flour food industry vibrating screen is to imitate the manual screening action, and realize the efficient and fine classification and screening of glutinous rice flour through the swinging motion of low-frequency, three-dimensional elliptical trajectory. The screen surface of the swing screen performs a swinging motion that combines horizontal circular motion with vertical throwing motion, and the material slowly diffuses on the screen surface in a spiral shape. This movement mode is similar to that of a manual hand screen, which not only allows the fine powder to fully contact the screen, but also stays on the screen for a long time, greatly improving the accuracy and efficiency of screening.

Start the motor, the eccentric wheel drives the main shaft, and the screen body swings in a circle around the central axis; the glutinous rice flour enters the screen surface from the feed inlet and diffuses from the center to the outside under the impetus of the swing; the fine powder passes through the screen, and the impurities or coarse particles slide along the spiral trajectory to the discharge port for discharge; the multi-layer screen can realize multi-level classification screening, and each layer screens out powders of different particle sizes.

What are the advantages of the glutinous rice flour food industry vibrating screen?

Effective dispersion of agglomerates: Horizontal circumferential and radial reciprocating motions make the glutinous rice flour particles continuously roll, flip and disperse on the screen, breaking its inherent sticky agglomeration, avoiding the "bridging" phenomenon, and ensuring that the powder can be evenly spread.

Extended material residence time: Compared with the high-frequency vibrating rotary vibrating screen, the swing screen has a relatively gentle movement, and the material stays on the screen for a longer time. This provides sufficient time and opportunity for the glutinous rice flour particles to have enough passing force to pass through the screen holes, thereby greatly improving the screening efficiency and accuracy, especially for fine screening.

Reduce glutinous rice flour blocking the screen: Continuous rolling and dispersing motions, combined with its own screen cleaning device (such as bouncing balls, ultrasonic screen cleaning), can effectively prevent glutinous rice flour particles from blocking the screen holes and maintain the permeability of the screen.

Reduce glutinous rice flour damage: The gentle screening method reduces the violent collision and friction between material particles, which not only reduces the generation of dust, but also protects the particle integrity of glutinous rice flour to the greatest extent, ensuring product quality.

Recommended mesh number of glutinous rice flour food industry vibrating screen

80-120 mesh: suitable for coarse screening or primary impurity removal, used for the production of ordinary glutinous rice balls, glutinous rice balls and other products with low fineness requirements. The 80-mesh screen has a larger aperture and high screening efficiency, which is suitable for large-scale production and reduces the risk of blockage.

120-150 mesh: suitable for medium and fine screening, meeting the needs of most food-grade glutinous rice flour, such as making traditional pastries (such as Qingtuan and Matuan). This range balances fineness and output, is suitable for the low-speed movement characteristics of the screen, and can effectively separate and retain powder.

150-200 mesh: suitable for high-precision screening, used for pastries or fine foods (such as glutinous rice flour masks, refined snacks). The 200-mesh screen has a smaller aperture, which can ensure extremely fine powder, but it needs to be equipped with a scanning or bouncing ball net cleaning device to prevent iodine blockage.

Application scenarios of glutinous rice flour food industry vibrating screen

The glutinous rice flour food industry vibrating screen is widely used in the production process of glutinous rice flour related foods, especially for production lines with high requirements for powder fineness and purity. Glutinous rice flour is often used to make traditional or modern foods such as glutinous rice balls, rice cakes, glutinous rice cakes, rice cakes, rice noodle skins, glutinous rice cakes, mochi, sticky rice sausages, etc. These products have very strict requirements on the particle uniformity, fineness and impurity-free of glutinous rice flour. The swing screen is mainly used for fine classification, coarse powder recovery and impurity removal after grinding glutinous rice flour. For example, in the production of glutinous rice balls and glutinous rice cakes, screening out overly coarse or agglomerated powder can effectively avoid rough taste and difficulty in forming; in the production of rice noodle skins or rice cakes, multi-stage screening can ensure uniform distribution of powder particles and improve the uniformity and appearance quality of steaming or baking. The swing screen can be configured with multiple layers of screens and flexibly matched with 80 to 200 mesh screens to achieve classification of glutinous rice flour of different particle sizes to meet the requirements of different foods for powder fineness.

In short, the glutinous rice flour food industry vibrating screen achieves efficient grading in gentle screening by accurately matching the physical properties of glutinous rice flour with process requirements. It is a key equipment for controlling product quality in the industrial production of glutinous rice flour food. By accurately controlling the particle size of glutinous rice flour, the overall quality and market competitiveness of the product are improved.
