Descrição

The Horizontal Wheat Scourer With Low Breakage Rate is a specialized wheat surface cleaning machine designed for flour mills, seed processing plants, and grain cleaning lines. Wheat kernels are oval-shaped, slender, and protected by a thin bran layer, but they also have a deep ventral groove that easily traps dust, sand, microorganisms, and fine impurities. At the same time, the wheat endosperm is fragile and can crack if the scouring action is too aggressive. This horizontal wheat scourer uses a gentle, controllable scouring action to remove surface dirt, mud, wheat hairs, light impurities, and microbial contamination while keeping the wheat kernel intact. It is an ideal solution for wheat cleaning before milling, têmpera, and further separation.

Horizontal Wheat Scourer Working Principle

Wheat enters the horizontal scouring chamber through the feed inlet and is evenly distributed by the feeding mechanism. Inside the chamber, a horizontal rotor with specially designed paddles rotates at an adjustable speed. The paddles gently throw the wheat against a perforated screen cylinder and wear-resistant inner plates. Through controlled friction and light impact, the surface impurities attached to the wheat bran are loosened and removed.

The perforated screen cylinder allows fine sand, dust, broken bran, and small impurities to pass through, while the whole wheat kernels continue moving forward along the chamber. At the same time, an integrated aspiration system removes light impurities such as dust, wheat hairs, chaff, and fine bran particles. The cleaned wheat is discharged from the outlet, ready for destoning, magnetic separation, têmpera, or milling.

The low breakage rate is achieved through optimized rotor speed, paddle angle, paddle-to-screen clearance, and optional variable frequency control. These design features allow the machine to clean wheat thoroughly without causing excessive impact or cracking.

Parameter

Features

• Low-breakage horizontal rotor design: The rotor is equipped with optimized paddles and a carefully controlled paddle-to-screen clearance to reduce hard impact on wheat kernels.

• Adjustable rotating speed with optional VFD: The scouring intensity can be adjusted according to wheat variety, moisture content, hardness, and impurity level, making the machine suitable for different wheat conditions.

• Wear-resistant perforated screen cylinder: The screen cylinder effectively removes sand, dust, and fine impurities while maintaining stable wheat flow and long service life.

• Integrated aspiration and dust control system: The machine removes light impurities such as dust, wheat hairs, chaff, and fine bran, improving both cleaning efficiency and the working environment.

Advantages

• Gentle scouring for fragile wheat kernels: Compared with aggressive wheat scourers, this machine reduces broken kernels, fine cracks, and bran loss, which is especially important for wheat with low moisture or thin bran.

• High cleaning efficiency for wheat surface impurities: The horizontal scouring action reaches the wheat surface and ventral groove, removing dirt, mud, microorganisms, and light impurities more effectively than simple screening.

• Flexible adjustment for different wheat qualities: Rotor speed, feeding rate, and aspiration volume can be adjusted to match soft wheat, hard wheat, durum wheat, and wheat with different moisture levels.

• Continuous and reliable operation: The heavy-duty rotor, balanced structure, and wear-resistant components ensure stable performance in continuous flour milling production.

Benefits

• Higher flour yield and better flour quality: Cleaner wheat with less surface contamination helps reduce ash content, improve flour whiteness, and increase usable flour yield.

• Lower breakage losses and less waste: Low breakage rate means fewer broken kernels and fines, reducing grain loss and improving economic benefits for flour mills.

• Protection for downstream equipment: Removing sand, dust, and surface impurities protects roller mills, sifters, purifiers, and conveyors from wear, blockage, and unnecessary maintenance.

• Cleaner and safer production environment: The enclosed structure and aspiration system reduce dust escape, improve operator safety, and help meet food hygiene requirements.
