Dehumidification for silo storage, conveying and mixing
To prevent condensation and moisture problems in bulk material and storage processes, dehumidification systems are often used. Silos, conveyors, and mixing plants operate more efficiently when the air is cool and dry. Storing dry bulk materials in silos or transporting powders in pneumatic conveying systems can be problematic. Reduced product quality, lost production, blocked pipes, and a need for intensive regular equipment maintenance are common requirements. Lower productivity and higher production costs are the result.
Operators of silos or conveying systems are often aware of the effects of excessive moisture. Relative Humidity (RH) levels are difficult to counteract as they change throughout the day and season.
Pneumatic conveying is also affected by increases in air pressure, as this also increases the likelihood of condensation forming. The moisture regain due to condensation causes many ingredients and powder that would otherwise convey smoothly, to stick together. As a result, these products build-up in conveying lines.
To minimize the effects of product build-up, mechanical devices such as vibration pads, hammers etc., are often fitted to bulk handling equipment
