Desiccant Dehumidifiers used in Spray Drying product area are manufactured by Hygro to maintain desired humidity and temp levels inside the manufacturing area. for more details please visit Click Here / Contact Our Engineer @ 9886144100 for more details. Increase Throughput From Spray Dryers Up To 30% Without Adding Capacity Spray Dryers require large quantities of hot air for drying. The quality of the final product is affected by the quality of inlet air entering the dryer. The Spray Dryer mixes heated air with an atomized (sprayed) liquid stream within a vessel (drying chamber) which leads to evaporation and produces free-flowing dry powder with a controlled average particle size. Thus, the inlet air has to be dry, free of contamination, foreign particles and odourless. However, since the ambient changes throughout 24 hours, 365 days a year, the humidity present in the air, entering the Spray Dryer is not constant. Thus, the drying temperature and time inside the dryer needs close monitoring to restrict loss due to varying level of humidity present in the inlet air. These varying inlet conditions need to be monitored by an experienced operator to adjust the parameters for stable outlet conditions.
Desiccant Dehumidifier for humidity control in chocolate storage rooms Installing a HYgro desiccant Dehumidifers can preserve the Chocolates by maintaining a conditions at 35±5% RH at 25°C (77°F) for it to retain its original flavour and aroma. For more details please visit
DESICCANT ROTOR The desiccant rotor is a high capacity desiccant media captivated in a circumference rim with radial spokes. The spokes attach to a central hub with integral sealed ball bearings. The sealed bearings ride on a solid center shaft. The rotor is held in place with a lock ring on each side the desiccant material, usually a silica gel impregnated into a support. This looks like a honeycomb, which is open on both ends. Air passes through the honeycomb passages, giving up moisture to the desiccant contained in the walls of the honeycomb cells. The desiccant structure is formed into the shape of a wheel. The wheel constantly rotates through two separate air streams. The first stream, called the process air. Is dries by the desiccant. The second air stream, called reactivation or regeneration air, is heated. It dries the desiccant. Technical Specifications Rotor material Desiccant: Solid silica gel Silica Gel Si02 - 82% Glass-fibre- 16% Acrylic surface coating - 2% Technical Data Density: 240kg/m3 Surface compression strength: >200kpa Water vapour absorption capacity :> 40% Max temp: 160Deg C PATENTED Desiccant Rotor Product NOT classified as harmful to the environment Properties No limitation of process air relative humidity. As long as no droplets are introduced in rotor during operation Dehumidification performance after continuous operation for: 5 years: approx. 90% 10 years: approx. 90% 15 years: approx. 90% Incombustible Washable in water or non alkaline detergent after saturation in humid air HYGRO DEHUMIDIFIER ADVANTAGES The Dehumidifier Manufactured by Hygro Tech is non cyclic, rotary type and removes the moisture by process of continues physical adsorption. The desiccant used by Hygro Tech is non toxic, non flammable with maximum moisture removal Capacity Hygro Dehumidifier can maintain Relative humidity (RH) as low as 1% regardless of ambient conditions.
moisture during PCB assembly can increase the number of failures during assembly, and decrease the circuit assemblies and its life. Exposure to high moisture during Printed Circuit Board (PCB) assembly and manufacturing, leads to Microscopic corrosion Adhesion failures Surface defects Decreased performance of the circuit board. Increase electrical resistance Decrease capacitance. Hygro Desiccant Dehumidifiers provide the ideal low humidity environment in the manufacturing, assembly and storage of these precision, high quality electronic Printed Circuit Boards since they are capable of maintaining RH as low as 1% or even lower at a constant level, regardless of ambient conditions.
