Problem
Moisture absorption by an ingredient being conveyed and condensation inside storage and conveying equipment often cause costly problems with pneumatic conveying systems that transport and store bulk materials. Moisture can affect the quality of the final product, spoil materials, inhibit the smooth transfer of ingredients, corrode equipment, and contribute to maintenance related downtime.
Many moisture related problems in pneumatic conveying systems have a toll on production levels, quality, and operating costs
Dry ingredients stored in bulk readily absorb moisture and quickly become sticky. The problem often manifests itself in the form of product agglomeration and adhesion to silo walls.
Problems associated with moisture inside storage silos and conveying systems often affect productivity, cause poor product quality, contribute to increased labor, lead to spoilage, and ultimately costs money.
Solution
Stulz DESICAiR dehumidification utilizes silica gel desiccant to remove water vapor from air. The amount of water held in the air is actually reduced. The result is dry air supplied to the conveying systems and bulk storage system. Old technology hot air systems simply raise air temperature without changing the specific humidity. The amount of water contained in the air remains unchanged. The desiccant dehumidification process does not rely on condensation as in refrigerant systems. Desiccant units are effective year round, even in sub-freezing conditions.
Our systems are designed to supply your process with dry air for pneumatic conveying. By combining the dehumidifiers with cooling coils, a customer can have an air stream that best fits the particular process.
By controlling the temperature and relative humidity inside the silo, we lower the dew point to a temperature that is less than ambient conditions. Since the dew point is never reached, we prevent the buildup of product on the interior of the silo walls, as well as decrease the likelihood for product lumping and mold growth.
Stulz dehumidification systems are an efficient and cost effective solution to your humidity and temperature control problems.
