Product overview
Precise grain separation by length for cleaner fractions and stable processing
The BST indented cylinder is designed for separating grain mixtures by length, helping remove impurities such as wild oat and other elongated admixtures from the main crop. It is also used for sorting cleaned grain into more uniform fractions, improving the quality of the finished material before further processing, storage or packaging.
BST machines are widely used in elevators, flour mills and groats mills where accurate fractionation is required. They are suitable for separating wild oat and cockle seeds from grain mixtures, as well as for technological operations such as separating oats from barley or distinguishing hulled and unhulled grains in cereal production lines.
The principle of operation is based on a rotating cylinder with specially shaped cells. Shorter particles enter the cells and are lifted before being discharged into a dedicated outlet, while longer impurities that do not fit into the cells remain outside and are directed into a separate tray. This creates a clear and efficient separation of the incoming mixture by particle length.
Thanks to its reliable mechanical design, stable rotation and straightforward discharge system, the BST trier delivers consistent performance in continuous operation. Models are available in different capacities, making the machine suitable for both medium-scale grain handling and larger production facilities that require dependable day-to-day sorting accuracy.

BST Overview
Two-stage length separation
The BST trier works in two sequential stages. The upper trier removes short impurities first, while the lower trier separates long impurities from the product flow to improve final grain quality.
01
Upper Trier
The upper trier is responsible for separating short impurities from the grain mixture. Smaller particles are captured and discharged separately before the material continues to the next stage.
02
Lower Trier
The lower trier separates long impurities from the pre-cleaned flow. This stage refines the mixture and helps deliver a cleaner, more uniform final product.
