Description

các High Capacity Square Plansifter For Flour Mill Sieving is a core screening and grading machine designed for modern flour mills that process wheat flour, maize flour, rice flour, and other fine powdery or granular materials. Flour and similar powders are not uniform products. They have a wide particle-size distribution, low bulk density, strong tendency to become airborne, and varying flowability due to moisture, fat, and electrostatic charge. Wheat flour also contains starch granules, protein particles, fine bran specks, germ fragments, and semolina or middlings that must be separated precisely.

This high capacity square plansifter is built around these material characteristics. It uses a compact square sieve body, multiple sieve sections, precision screen meshes, and a gentle gyratory motion to classify flour and powdery materials by particle size. It separates fine flour, middlings, semolina, coarse bran, and other fractions in one continuous, enclosed operation. For flour mills, it is not simply a screening machine. It is a high-capacity purification and grading platform that protects flour quality, improves extraction rate, and keeps the milling line running efficiently.

Square Plansifter Working Principle

các High Capacity Square Plansifter For Flour Mill Sieving works through a controlled, multi-layer sieving process:

1. Uniform feed distribution
   Ground flour and powdery materials enter the plansifter through an inlet and are evenly distributed to each sieve section. Because flour is light and easily airborne, the feeding system is designed to avoid dust leakage and uneven loading.

2. Gyratory motion and material movement
   A motor drives an eccentric counterweight system, causing the square sieve body to perform a horizontal gyratory motion. Flexible suspension rods or rubber springs support the sieve body and allow smooth movement. The flour particles move across the inclined screen surface in a circular path, spreading evenly and separating by size.

3. Multi-layer precision screening
   Each sieve section contains multiple screen frames with different mesh sizes. Fine flour passes through the fine screens, while coarser particles remain on the upper screens. By arranging screens from coarse to fine, the machine separates flour, middlings, semolina, bran, and other fractions at the same time.

4. Discharge of different flour fractions
   Each screen layer has its own discharge outlet. Clean flour, coarse flour, fine bran, and other products are discharged separately. This makes the plansifter suitable for producing different flour grades and for controlling flour quality in a flour mill.

5. Screen cleaning and dust control
   Rubber balls, brushes, or other cleaning devices keep the screen meshes open and reduce blockage caused by moist or electrostatic flour. The entire sieve body is enclosed and can be connected to a negative-pressure aspiration system, preventing flour dust from escaping into the workshop.

Features

1. High-capacity square sieve body with multiple sections
   The square plansifter is designed with a compact square structure and multiple sieve sections. This gives a large sieving area in a small footprint, allowing high output while fitting easily into modern flour mill layouts.

2. Precision screen grading for flour and powdery materials
   The machine uses multiple layers of interchangeable screen meshes. Operators can adjust mesh size according to flour fineness, wheat variety, moisture content, and target product grade. This is essential for flour with a wide particle-size distribution and fine bran specks.

3. Gentle gyratory motion with effective screen cleaning
   The horizontal gyratory motion moves flour gently across the screen surface. It avoids violent vibration that can damage starch or compact the material. Rubber ball cleaners and brushes help prevent screen blinding, especially when flour is fine, hygroscopic, or electrostatic.

4. Enclosed dust-tight and food-grade construction
   The sieve body, inlets, outlets, and inspection doors are sealed to control flour dust. Contact parts are made of food-grade materials. This design reduces dust explosion risk, improves worker safety, and meets food hygiene requirements.

Advantages

1. High capacity per floor area
   Because the square plansifter uses a compact multi-layer design, it can handle large volumes of flour and powdery materials without occupying excessive floor space. This is a major advantage for flour mills with limited building area but high production targets.

2. Accurate separation and stable flour quality
   Flour quality depends on precise separation of fine flour, bran specks, germ, and coarse particles. The plansifter’s multi-layer screening and adjustable mesh sizes provide sharp separation, helping mills produce consistent flour with better color, texture, and baking performance.

3. Low screen blockage and reduced maintenance
   Flour particles can blind screens when they are moist, oily, or electrostatically charged. The gyratory motion, proper screen tension, and effective cleaning devices reduce blockage and extend screen life. This lowers maintenance frequency and production downtime.

4. Energy-efficient, dust-free, and safe operation
   The machine uses an optimized drive system and balanced gyratory motion to reduce power consumption and vibration. Its enclosed structure and aspiration connection keep flour dust under control, improving workplace safety and helping mills meet dust control and food safety standards.

Benefits

1. Higher flour extraction and better product value
   By accurately grading flour and separating bran and coarse fractions, the square plansifter helps increase the extraction rate of high-grade flour. Mills can sell cleaner flour, reduce waste, and improve profit per ton of wheat.

2. Consistent quality for different flour grades
   The machine can be adjusted for bread flour, noodle flour, cake flour, whole wheat flour, and other products. This flexibility allows flour mills to respond to changing market demand without replacing major equipment.

3. Lower operating cost and longer equipment life
   Reduced screen blockage, lower power consumption, and easy maintenance mean lower cost per ton of flour. The robust square frame and balanced motion also reduce wear on bearings, suspension parts, and screens.

4. Cleaner and safer flour mill environment
   Flour dust is combustible and harmful to workers. The enclosed design and dust control system reduce airborne flour, lower explosion risk, and create a cleaner working environment. This supports both occupational safety and food hygiene.
