Crop Ventilation Systems Efficient Ventilation for Grain Storage

Why Safe Storage Matters When grain is harvested, securing safe storage is the next priority. Regardless of the conditions under which the grain is harvested, it is an organic material that contains moisture, making it vulnerable to mould growth, fungal contamination, and insect infestation if not stored properly. It is all about maintaining the right moisture levels, temperature, and aeration of the stored grain. A well-constructed and well-operated storage solution is essential to ensure safe storage that meets food safety standards while avoiding quality losses and financial consequences....

On-Floor Systems with Lateral Ducts A common and cost-effective method of supplying air to grain storage is by using lateral ducts; these semi-circular ducts are positioned on the floor, above floor level. Kongskilde’s lateral ducts ensure optimal air distribution, making them ideal for all crop types, including small seeds. With varied sizes and tapered design options, the ducts can be combined to suit any drying or aeration setup, providing a highly customizable solution for grain storage and drying facilities. This solution is especially effective for integration into existing flat storage...

Underfloor Aeration Systems Drive-over Ventilation Grates Drive-Over Grates & Underfloor Shuttering An on-floor drying and storage solution with underfloor aeration channels and perforated drive-over grates provides a fully unobstructed floor area, allowing easy access for lorries and other traffic. The channels are formed using shuttering boxes, also referred to as steel troughs or formers. Once the channel system is positioned and embedded in the concrete floor, the drive-over grates are installed in the shuttering, functioning as below-floor laterals. For bulk and free-flowing grain and seeds...

Teyfun Point Aerator Teyfun Point Aerator The Teyfun Point Aerator is designed for aeration and limited drying of grain and seed crops. It is a flexible tool that can supplement on-floor drying systems in flat storage or for temporary grain stacks where no aeration system is installed. Portable and easy to relocate, the Teyfun can blow cool ambient air into the grain to improve ventilation or use its suction function to extract warm air, remove heat pockets, and help prevent combustion risks. • Available in two models: KM 15 with 1.5 kW motor and KM 22 with 2.2 kW motor Galvanised perforated...

Backwards curved rotor blades ensure high airflow and optimal efficiency. Rain cover for outdoor installation available as optional. Kongskilde offers a wide range of high-volume lowpressure blowers ideal for drying and aeration of grain and other crops. Suitable for different applications The air flow rate of this type of blower varies little with changes in the air pressure resistance, caused by the different types of crops in on-floor-storages, silos or driers. The HVLs are therefore an ideal solution, also for smallseed crops like rape seed having a higher resistance to the air flow. Owing...
