Drying System

We offer different types of drying systems depending on the nature of products to be dried and the characteristics of dried product required. The drying systems are designed for one-step transformation of liquid feeds/ wet cakes / pastes to powder. Depending on the nature of product the suitable material of construction is selected for product contact parts. The system is supplied as a turnkey equipment consisting of following systems.

Slurry preparation/ Mixing / Feeding System. Air heating system. Feed atomization/ dispersion/ agitation system. Dry product collection/ conveying system. Dust / Fines collection of either one or combination of following systems. High efficiency cyclone separator. Bag filter. Wet scrubber. Electrostatic precipitator. Controls and instrumentation comprising of simple motor control center and indicating and controlling instruments. Option of PLC controlled system for automatic operation of the complete plant is also offered. The drying systems are either open loop, semi closed loop or closed loop depending on the nature of solvent in the feed and the necessity of recovering the solvent. Depending on the nature of feed following types of drying systems are offered.

Special features:

Semi or fully automatic cleaning system Rotary atomiser with inert gas purging Air disperser for rotary and nozzle atomiser Controlled noise level

Explosion protection for Drying chamber Weather proof finish for outdoor installation Wide range of applications, sizes and Configurations. Tailor made system as per customer requirement..

Advantages:

Flexibility of drying different product in one dryer. Shortest down time for maintenance. Efficient controlling system for powder quality.

Save energy. Increased production rate. Better powder quality.

Applications:

Dyestuffs, Pigments Starch Detergents Milk Powder Plants Food Industries Herbal Extract

Protein Hydrolysate Ceramics, Clay Minerals Pharmaceuticals Enzymes

Spray dryers are offered for feeds in liquid form containing either water or any other solvent. Feeds may be solution, slurry or emulsion. Depending on the particle size of the final product required any one or combination of following atomization system is used. Two fluid atomization. High pressure single fluid atomization. Rotary disc atomization.

Typical applications of spray dryer are Dyestuffs, pigments, starch, detergents, milk powder, fruits, herbal extracts, food flavours, ceramics, china clay, enzymes etc. These pharmaceutical spray dryers, industrial spray dryers are usen in most of the pharmaceutical imdustries.

Flash dryers are used for drying of wet cakes which are sensitive to heat. There are different variations of flash dryers available depending upon the need to disperse the wet cake or pastes. These are:

Spin Flash Dryers: This consists of a horizontal agitator, which disperses the feed while it comes in contact with the hot air and gets dried.

Cage Mill Flash Dryers: This consists of a vertical pin type rotary and stationary cages. The wet feed is fed at the center of the rotating cage, where it comes in contact with hot air. The rotating cage disperses the feed while drying.

Rotary dryers are used for wet cakes, which are easily breakable and dispersible. The rotary dryer consists of a rotating drum with angle lifting blades which lift the feed as the drum rotates and showers it in the steam of hot air flowing through the drum. GMP plants are offered for pharmaceutical, food, and biochemical applications.

Fluid bed processing involves drying, cooling, agglomeration, granulation, and coating of particulate materials. It is ideal for a wide range of both heat sensitive and non-heat sensitive products. Uniform processing conditions are achieved by passing a gas (usually air) through a product layer under controlled velocity conditions to create a fluidized state.

We offer Fluid bed drying process which is well suited for powders, granules, agglomerates, and pellets with an average particle size normally between 50 and 5,000 microns. Very fine, light powders or highly elongated particles may require vibration for successful fluid bed drying.
