Horizontal wheat scourer is widely used in the process of cleaning wheat flour, especially in medium and large factories. Our horizontal wheat scourer is primarily designed for applications in the first and second cleaning sections for the surface treatment of wheat. First, it is used to remove impurities and adhering contamination like dust, sand, earth lumps, and hair, etc. Second, it is used for improving product sanitation by reducing the microbe count like bacteria and the insect, insect fragment count, and other fifth counts. Besides, the scouring rotator can also reduce mud and other impurities in the cream of wheat.Generally speaking, our horizontal wheat scourer is equipped with an aspiration channel or an air-recycling aspirator at its discharge. The unwanted particles are discharged afterward by passing through the holes of the arc-shaped screen to ensure lower percentage of fine wheat damaging. Our horizontal wheat scourer efficiently removes detached hull particles or surface contamination from the wheat. What’s more, with the appropriate rotor and screen jacket designs, our horizontal wheat scourer is also successfully used in intensive durum scouring and oats processing.Our horizontal wheat scourer ’s drum sieve is welded and manufactured with high-quality stainless steel, and its beating plate is made of high-quality carbon steel. Our horizontal wheat scourer has many advantages like compact structure, high precision, dynamic balance, stable running, low noise, small vibration, low power consumption, easy operation and long service life.

Benefits of Dry Scrubbing

Researchers with Omas Industries, Padova, Italy, have developed a new approach to scouring wheat in the cleaning house.

This approach, called dry scrubbing technology (DST) combines existing technology in a new way to remove a portion of the bran gently to reduce the amount of mold, bacteria, mycotoxins, and the portion of the kernel’s pericarp that resists water penetration during tempering.

The procedure has been under development since 2015 and currently is being used at a flour mill near Venice, Italy.

Plans call for rolling out DST at a U.S. location some time later this year or early in 2024.

How DST Works

Traditional scouring is done in a horizontal machine, while DST is a vertical process. Wheat is fed into the top of the machine. As kernels fall, they are scrubbed by eight vertically-stacked abrasion disks, which are made from a composite material with a very fine grit to ensure that the abrasive action is not too aggressive. The disks are surrounded by stainless steel grates angled to reduce the aggressiveness, as well.

Each DST machine also is equipped with a high-pressure fan generating roughly double the force found in a conventional scourer. That forces air between the rotors to remove the bran. It also helps cool the wheat, so excessive heat is not generated.

The DST machine is outfitted with an outlet gate with an actuator. A control panel allows the operator to select a target amperage of the drive motor, which in turn, controls the actuator, thereby regulating the quantity of bran removed from the kernel.

In addition, equipment components are coated with a food-grade epoxy paint, and belts are equipped with rotation sensors.

The DST is installed after the cleaner and destoner in the cleaning house. You want the FM and the stones out of the product flow before it gets to the fine grit in the DST.

DST Benefits

The charts show both economic and hygienic benefits of the DST approach compared to traditional scouring. Data for these charts were developed during testing of the system in Italy.

Overall, the DST process removes 0.5% to 1.0% of the pericarp from the kernel. Not only is that the most water-resistant portion of the kernel, but it also contains a significant amount of contaminants, including mycotoxins like vomitoxin and residual pesticides.
