Kozak grain aerators

The KOZAK Grain Aerator by Technomaszbud. A grain aerator is a device used for aerating cereal grains. This process aims to improve the quality of the grain by increasing its “respiration” through the introduction of air. Aeration stimulates enzymatic activity, which positively affects the nutritional properties of the grain. Aerating the grain is particularly important when the grain is intended for storage, as it significantly prevents spoilage by inhibiting the growth of mold and fungi and by preserving grain quality.

The KOZAK grain aerators manufactured by Technomaszbud consist of two main components: a fan and an aeration chamber. The fan generates an airstream, which is directed into the aeration chamber. In the chamber, the grain is exposed to air for an appropriately selected period.
The aeration time depends on the type of grain and the storage conditions.

Optimizing grain quality through aeration is a key process in agriculture and the grain-milling industry. This procedure offers numerous benefits that directly affect the durability and market value of the product. Its primary goal is to reduce post-harvest grain moisture and ensure proper storage conditions. It is important to remember that the maximum allowable moisture content for safe grain storage is approximately 14.5%. For oats, this value should not exceed 12.5%. Moist grain must be dried, and KOZAK grain aerators from Technomaszbud are ideally suited for this task.

In the Polish grain and milling industry, grain aeration is an integral part of the technological process. It is not only a standard operation but also an essential step with a significant impact on the quality of the processed material. Widely used in silos and grain warehouses, aeration helps maintain high product standards.

It is worth emphasizing that grain aeration not only delivers tangible benefits in terms of improved product quality but is also a relatively simple and cost-effective process. These advantages make it a crucial procedure for achieving optimal results in grain production. Technomaszbud offers KOZAK grain aerators as an essential solution for effective aeration.
