There are so many imputities in the grains, which also referred to as fines (any dirt or particles smaller than the grain) can collect in areas inside the storage silo. These pockets of fines can cause hot spots inside the silo, which adversely affects the aeration of the grain or seed. This can also result in moisture collecting in these areas, which can cause rot, mould and other damage to the grain.

　　1. Pre-cleaning grain before storage plays two vital roles:

　　Adding value to the grain through the removal of dirt, impurities and damaged particles.

　　Ensuring a longer life of the grain whilst it is in storage.

　　2. The importance of cleaning before storage

　　The quality of the grain or seed starts to deteriorate as soon as it has been harvested. It is therefore vital that dirt and impurities be removed as soon as possible, to delay the deterioration process and ensure that the product being stored is of a high quality for end users.

　　3. Cleaned grain and seed is of a higher quality, which helps preparing for next processing and deep-processing.

　　WIN TONE'S grain cleaners are the first and most important piece of equipment used to clean any type of grain, seed or beans. All the models can be supplied with an optional air extraction fan, galvanised ducting and receiving cyclone for the collection and recovery of all of the light impurities.

　　We have been an innovator in the field of grain and seed handling and cleaning for the last 27 years, and have developed our own range of grain and seed cleaning and handling equipment that can process at capacities of as high as 120 tonnes per hour.

　　Our complete grain cleaning plants work on the tried and tested principle of vibrating screens and air extraction to separate the grain from impurities. These impurities include anything larger than the grain such as sticks (also known as overs), and anything smaller than the grain like broken kernels or sand, as well as anything lighter than the grain such as husks and dirt (also known as fines).

　　We have a wealth of knowledge in developing solutions for the handling and processing of grain, seed and cereal products.
