Moisture Control in Powder Food Powdered foods like juice concentrates, whey powder, protein supplements, soup powders, cocoa, gelatin, dehydrated soft drink concentrates, instant coffee powders and milk powders are gaining popularity in the growing world. The presence of moisture during processing of food powders and beverage powders causes: Stickiness, Lumping and caking, Cluster formation, Reduce shelf life Recommended RH for Powdered Foods Food Powder Temperature in ºC RH % Instant Coffee Processing 26ºC 20% RH Fruit Powder Handling 20°C – 22°C 35% RH Tomato Powder Production 19°C – 23°C 25% – 35% RH Dry Soup Packaging 21°C 20% RH Powdered Drink Mix Packaging 21°C 20% RH Cooling of Spray Dried Milk Powder 10°C 35%- 40% RH Milk Powder Packaging 22°C– 25°C 35% – 40% RH Whey Powder Manufacturing/Storage 21°C – 26°C 15% – 30% RH Hygro Tech Engineers has a complete turnkey solution in treating moisture problems for powdery products. for more details please contact www.hygrotechindia.com / 9886144100

Desiccant Dehumidifier to maintain Humidity/Moisture for Switchgear rooms are manufactured by Hygro tech engineers. Kindly visit www.hygrotechindia.com / contact our engineer @ 9886144100 for more details. The high humidity level in a switchgear room causes several damaging effects. It results in condensation of moisture on the switchgear surfaces when there is a sudden change in temperature because of outside (Weather) or inside (Air Conditioning) factors. The condensed moisture on the switchgear surface is detrimental to switchgear. The moisture may condense on switchgear insulator surface causing it to absorb moisture. The best way to prevent damage from condensation and corrosion is to control the humidity and airborne molecular contamination in the switchgear rooms. Switchgear failure due to short-circuiting can be avoided by controlling the moisture levels to less than 50% RH at ambient condition in the room or in conjunction with an air-conditioner if the switchgear needs temperature controlled environment also. Dehumidifying the switchgear room ensures that the insulating components do not fail and power outages are prevented due to high humidity.
Desiccant Dehumidifier for Moisture Control in Safety Glass manufacturing through Hygro Dehumidifiers. for more details please visit www.hygrotechindia.com Effects The hygroscopic film absorbs moisture and leads to Improper bonding of two layers of glass Reduces clarity of the glass Solution Install Desiccant Dehumidifier to control The RH level in the glass laminating area at 20-22% with 20°C (68°F).
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.

I pharmaceutical Industries Vial Filling operations entail include conveying of powdered substances to packaging areas in a high velocity air-stream and filling minute quantities of the powder in the vials and capsules. High humidity may cause the powder to stick and cluster together in the conveyor thus hampering air conveying and filling operations. Hygro Tech Engineers has a complete solution to maintain the low RH levels in the desired areas in pharmaceutical industries For more details please visit www.hygrotechindia.com
Improper drying can damage the product. Products needs to be dried to recommended moisture content level & optimum drying is difficult given the variability of the product being dried and thus, proper understanding of the drying requirement and process is extremely important. Drying criteria vary from product to product, given the unique characteristics/requirement of different products. Some products are more temperature sensitive than others and hence, require special type of drying. Products, generally have surface moisture (present free on the product surface and can be removed easily) and inherit/core moisture (which is difficult to remove) and require special drying techniques. Drying is also often the largest energy consuming process, and the process needs to be understood to effectively to rationalize energy needs. It is important to understand the drying techniques and technologies to reduce spoilage and enhance the quality of the product. Hygro provides complete drying solution with HYgro products in applications like food drying, Pharmaceutical, mechanical industry, Aviation, Leather, spices, tea & coffee drying, film drying, parachute drying, investment casting drying etc...
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.
