Clean and safe: How trommel screen cleaners and co. are used as pre-cleaners for grain and seed cleaning

As an experienced milling company, we know how important effective grain cleaning is for the quality and safety of flour and other grain products. Contaminants such as stones, dirt, dust, and weed seeds can not only affect quality, but also pose health risks to consumers. Therefore, here we would like to offer basic information on grain cleaning, including some facts about the use of trommel screen cleaner as a pre-cleaner for grain and seed cleaning. Let us show you how we can help you make your production safe and effective.

How grain cleaning works

Step by step to purified grain

Grain cleaning is an important process in the milling industry as it ensures that the grain is free from impurities and foreign bodies that can affect the quality of the final product. Grain cleaning consists of several stages aimed at removing all impurities and preparing the grain for the following processing steps.

Grain cleaning is an essential part of the milling industry. There are different types of grain cleaning, which focus on the type and severity of impurities. Coarse cleaning and black cleaning are two important types of grain cleaning. Coarse cleaning deals with coarse impurities such as stones and dirt, while black cleaning focuses on removing finer impurities such as sand and dust. Both types of grain cleaning are necessary to ensure that the final product is of the highest quality.

With this technique succeeds grain cleaning

There are different methods of grain cleaning, which focus on the type and severity of impurities. In this article, we will focus on three methods of grain cleaning: the sieve cleaner, the air classifier, and the drum sieve cleaner. The sieve cleaner is often used for coarse cleaning of grain, while the air classifier and the drum sieve cleaner are used for black cleaning. It is important to select the correct method for the type of contamination to ensure that the final product is of the highest quality.

Sieve Cleaner

The sieve cleaner is one of the most common methods for coarse cleaning of grain. A sieve with different mesh sizes is used to remove impurities such as stones, dust and dirt from the grain. The grain is placed on the sieve and set in motion by a rotating motion so that the impurities fall through the openings in the sieve and are removed. Sieve cleaners are simple and cost effective and are often used in combination with other cleaning methods.

Windsifter

The air classifier is usually used for black cleaning of grain. It is a type of dust removal machine that blows the grain through a stream of air and removes the fine impurities. The airflow is adjusted to blow away the lighter impurities, such as dust and dirt, while leaving the heavier grain behind. The air classifier is particularly effective at removing light impurities such as sand and dust.

Drum sieve cleaner

The drum sieve cleaner is another method for black cleaning grain. Here, the grain is passed through a rotating drum equipped with various openings. Impurities smaller than the openings fall through the sieve, while the grain remains on the drum and is discharged from the machine. Drum sieve cleaners are particularly effective in removing weed seeds and other smaller impurities.

From purified grain to flour!

With purified grain to wholemeal flour

Best wholemeal flour. With TREFFLER milling technology.

Cleaned grain serves as a basic prerequisite for the qualitative milling of wholemeal flour. This is possible dust-free by means of our milling technology and especially the Millomat. Due to the fully automated milling in the TREFFLER Millomat, the milled material heats up only minimally and thus retains all important nutrients. Thus, the processing of seeds into high-quality flour is possible without any problems.
