The Role Of Grain Cleaning Machine In Flour Processing

Mar. 21, 2024

In the regular operation of the complete set of flour processing equipment (flour machine), raw grains tend to accumulate in different parts, resulting in varying levels of residue. It's essential for equipment operators to promptly clean up these raw grain residues to maintain equipment hygiene and ensure normal operation.


The complete set of flour processing equipment is primarily utilized in flour mills, serving as an indispensable component for their operations. To optimize its performance and ensure production efficiency, Pingle Machinery advises timely removal of grains and other impurities from the equipment during usage. In the following discussion, Pingle Machinery will provide a brief analysis of the importance of using a grain cleaning machine to remove grains from the flour processing equipment, aiming to assist you in achieving better operational efficiency in your flour mill.

Why Do We Need to Clean up the Grains in the Flour Mill Processing Equipment?


1. On one hand, enhancing the technological efficiency of the complete set of flour processing equipment ensures product purity and safeguards public health. Simultaneously, it reduces transportation and storage costs.


2. Wheat may contain bulky and lightweight impurities like straw, weeds, paper scraps, and hemp rope. These impurities have the potential to clog the conveying pipeline, disrupt smooth production flow, or obstruct the feeding mechanism of flour processing equipment. This can lead to uneven feeding and reduced feed volume, subsequently diminishing the technological efficiency and processing capacity of the flour mill equipment.


3. When wheat contains hard impurities like stones and metals, it poses a risk of damaging the cleaning machinery during the manufacturing process. This damage can adversely affect the technological efficiency of the complete set of flour mill processing equipment and shorten its service life. Additionally, the collision and friction between hard impurities and the metal surfaces of the flour milling machine may generate sparks, leading to potential fires and dust explosions.


Use Grain Cleaning Machine to Clean up Impurities


What role does the grain cleaning machine play? The destoner machine is a key component of grain cleaning equipment. Throughout harvesting, transportation, and storage, grains inevitably accumulate various impurities such as soil, pebbles, sand, and grass. Prior to processing, it's essential to cleanse the grains using the grain cleaning machine. Failure to do so can compromise product quality, jeopardize human health, and even impede the performance of subsequent flour mill processing equipment.


The destoner is an innovative and highly efficient grain cleaning equipment. It's designed to eliminate both large and small impurities from various grains like wheat, beans, rice, and sorghum. By leveraging the disparity in specific gravity and suspension velocity between particles and stones (or sand), it separates stones from the flowing grains, dividing the grains into lighter and heavier components. This equipment comprises two sieves: the upper sieve facilitates the latter function, while the lower sieve facilitates the former function.


The presence of impurities in wheat can significantly diminish product purity and compromise the quality of the final product. Hence, the cleaning of wheat is a crucial step in the flour manufacturing equipment process.
