Importance of Grain Cleaning

Harvested grain is usually quite clean. Often the operative word, as this depends on many key factors; using the correct settings and volumes, grain drying, no heat damage occurring during harvest and grain not breaking - many factors that are difficult to control. In addition, the quality of the grain begins to deteriorate as soon as it is harvested, so dirt and impurities must be removed to slow down the deterioration process and ensure that the stored grain is of good quality for the end user.

Therefore, it is highly recommended to pass the harvested grain through a grain cleaner and/or pre-cleaner to ensure that the quality of the grain is optimized before it enters storage.

Pre-cleaning grain prior to storage serves two important purposes.

1. to ensure a longer life of the grain during storage

2. add value to the grain by removing dirt, impurities and damaged particles.

The importance of cleaning grain prior to storage is important for several reasons. Foreign matter, also known as fines (any dirt or particles smaller than the grain) may collect in areas within the storage silo. These pockets of fines can cause hot spots to develop inside the silo, which can negatively affect the aeration of the grain. This can also cause moisture to collect in these areas, which can lead to grain spoilage, mold and other damage.

Additional impurities can also take up valuable storage space in the silo - an unnecessary cost that can be avoided if the grain is cleaned before it goes into storage. Impurities can also contain harmful or toxic seeds or grains that can cause further damage and negatively affect the quality of the grain.

Clean grain is of higher quality and therefore better priced than grain filled with impurities. Even if a grain producer does not have its own storage facilities, clean grain provides a higher return on investment for the producer. Grain rejected by buyers or cooperatives often results in sellers incurring cleaning and resubmission costs that can ultimately be avoided.

Grain cleaners are the first and most important piece of equipment used to clean any type of grain, seed or legume. When analyzing all the elements that can affect grain quality, it makes good business sense for grain producers to seriously consider purchasing their own grain cleaners. It is estimated that the cost of a grain cleaner can usually be recovered within two to three seasons, making it a viable purchase even for smaller grain producers.

Innovation in the field of grain cleaning

We are an innovator in the field of grain handling and cleaning. We have developed a range of grain cleaning machines capable of handling grain at a capacity of up to 120 tons per hour.

All models of our grain cleaning machines can be used to clean a wide range of different grains, for pre-cleaning or fine cleaning. This is achieved by changing the settings on the machine and the ability to install different screen sizes on the removable screens.

These easy-to-operate machines work according to the tried and tested principle of vibrating screens and extraction to separate the grain from impurities. These impurities include anything larger than grain, such as bars (also known as residue), anything smaller than grain-like fractions or sand, and anything lighter than grain, such as husks and dirt (also known as fines) .

All models can be equipped with optional extraction fans, galvanized ducts and receiving cyclones for the collection and recovery of all light impurities.

We also offer other machines for cleaning, separating and classifying grains, seeds and cereals. These include de-stoners and gravity separators.

Our process division works extensively in the agri-food sector, providing solutions for the storage, conveying, cleaning, separation, grading, mixing, sorting and bagging of grain, seeds and cereal products.
