Available as an option on new equipment, or as a retrofit upgrade for existing machines, Kuhn has introduced a dust control system for its range of straw bedders.
Kuhn’s Cleanstraw system reduces dust in livestock buildings by applying a fine mist of water to straw as it is distributed for bedding purposes.
The system comprises a 64 litre water tank and three misting nozzles mounted at the exit of the straw blowing chute. Nozzles are fed by a 12 volt/15 amp pump which provides water at a flow rate of 1.8l/min, enough to treat 12 to 18 bales of straw at a rate of one litre of water per 100kg of straw, says the manufacturer.
Applying a mist of water at this rate and in this way eliminates excessive levels of airborne dust by reducing the amount of time that these particles remain suspended in the air, says the manufacturer. Trials have shown that the air in a typical livestock building will be dust-free within 30 seconds after straw-blowing with the new system, compared to several minutes under normal conditions, adds Kuhn.
Cleanstraw is available for all Kuhn straw bedders and mixer wagons equipped with a blowing turbine. These include the Polydrive-equipped range of Primor straw bedders and feeders and the Profile Plus range of mixer wagons with straw bedding capabilities.
Mounted at the front of the machine, the systems’ nozzles and pump components are protected against blockages by a suction filter, and all the system’s components sit within the original footprint of the machine. The water tank is equipped with a drain valve for cleaning and maintenance and is transparent allowing water levels to be checked. A pressure gauge and manually operated thumbwheel are used to adjust tank pressure and water flow.
The system is automatically activated when the feed system is engaged and can also be armed or disabled via an in-cab switch.This enables users of a combination straw bedding and feeding wagon to turn the system on when blowing straw for bedding, or off when dispensing feed.
