Spray Dryers are widely used in many process industries for drying the materials. This is designed with a large cylindrical and vertical chamber into which the material is fed in the form of small droplets. In addition to this, the hot air is also fed to generate heat in the chamber for completing the evaporation of liquid.

Fluidized Spray Dryers are extensively used in various industries for dry sticky products. The working of the system is simple, based on spray drying and fluid bed drying technologies. Ensure to achieve improved aroma retention, it is also suitable for drying hygroscopic, fats and sticky products that are difficult to handle. Operation:
Down to the fluid bed, a spray nozzle atomizer is present from where the spray is created and agglomeration incorporating finer, recycled material takes place
Exhaust air moves out through the roof causing agglomeration in the spray zone
A recirculation system is integrated that uses cyclones or bag filters, or a combination of both for recycling fines to the spray dryer chamber
This process yields non-dusty, free flowing agglomerated powders with high flavor retention
Cause drying at low temperature
Highly thermal efficient
Yields non-dusty, free flowing agglomerated powders with high flavor retention
Specially designed spray drying chamber for efficient drying
Long production time between CIP
Can be integrated with spray dryers to achieve safer temperatures without the risk of over-drying
Nozzle atomization for optimum spray of feed material
Options in air distribution for complete control of air flow
Cage Mill Flash Dryers are specifically designed for drying of relatively hard lumpy feeds. The excellent design, efficiency and automatic control make the operation of the dryer seamless and hassle free. The system is wisely designed by implementing advanced technology to ensure excellent fuel efficiency. Operation:
The feed is introduced through the rotating cage at the centre
Here, it comes in contact with the hot air
In this cage, the feed gets scattered into the flash tube
It leads to instant drying of feed without any degradation
Compact design saving a lot of floor space
High thermal efficiency
Effective crushing of lumps
Integrated with vertical pin type stationary and rotary cages
Incorporated with latest technology, these Spin Flash Dryers are widely used for dry high-viscosity products, pastes and filter cakes. It is specially attached with an agitator that breaks the cake into pieces. Designed to achieve fast operation, this dryer is proved to be ideal in applications where very fine powder as output is required. Operation:
A screw feeder is attached through which the material is fed into a vertical drying chamber with the help of a variable sped drive
This is heated by air and at the same time a specially dis- integrator disintegrates the material
Direct or indirect heating of air is applied depending on the application
Dry powder is collected through cyclone separator/ bag filter or with a combination of both
Flexible and efficient operations
Eliminates every possibility of sticking, accumulation or deposits
User friendly design
Easy periodic and shutdown maintenance schedules
Ensure emission of clean exhaust process air with effective bag filters
Yields super fine powder to eliminate the need of milling
Specially designed chamber for drying of highly flammable products
Integrated Fluid Bed Dryers are specially developed for use in industries of toxic products, oxygen sensitive products, or flammable solvent wetted materials. The advanced technology of the dryer makes it capable of handling heat sensitive materials that are dried at temperatures lower than the boiling point due to reduced vapor pressure. Usp:
Excellent heat and mass transfer rate
Ideal for heat sensitive materials
Customized for increasing capacity or reducing bed area
Capable of handling toxic products, oxygen sensitive products, or flammable solvent wetted materials
Continuous Vibration Fluid Bed Dryers is specifically designed for direct or indirect heating depending on the properties of substance to be dried and other technical constraints. It is suitable for achieving heavy heat and mass transfer values by passing the drying air through a bed of the solid to be dried. Integrated with advanced technology, the dryers offer controlled and uniform drying in short lead time. Usp:
Customized design maintains the crucial thermal equilibrium for correct moisture content of material
Rotary Dryers are suitable for applications where moisture content in the feed is required to be minimized. It is constructed with a large sized rotating cylindrical tube with internal fin lining supported by steel frames or beams. Aligned on a slight slope, these are widely used in industries where the feed has high moisture content and relatively longer residence time. Usp:
Ensure uniform and efficient drying
Durable and compact design that can withstand heavy load
Suitable for large volume production
Smooth movement of material throughout the barrel
Convenient to repair in case of any problem
Suitable for handling diverse applications with varied material characteristics

Spray dryers consists of a large cylindrical & usually vertical chamber. In to which material to be dried is fed in the form of small droplets. And hot air is fed to supply the heat necessary to complete evaporation of liquid.
Spray drying process is applicable to a wide range of products and industries.
Shachi handles the project ranging from laboratory size to large industrial spray dryer processing lines and plants.
Design Consideration of Industrial Spray Dryers : Co-current type : Feed and hot air is from same side. Feed is from rotary atomiser and nozzle.
Counter current : Feed is from top side and hot air from bottom side. Feed is from from rotary atomiser and nozzle.
Co- counter type : Feed is from bottom side and hot air from top (Fountain) side. Feed atomisation is through pressure nozzle or two fluid nozzle.

We have gained expertise in manufacturing a wide range of flash dryers that are extensively used for drying powders and granules, crystalline material. Wet material is diffused in to the stream of hot air or gas fetched through a drying duct. There are cyclones or bag filters for product separation and with the help of flash dryers, feed materials such as powders, gels, slurries, granules and flakes can be easily processed.
Back mixing of the wet feed with a portion of dry product for pastes, or sticky materials for producing a suitable conditioned material is required. Our flash dryers are used in industries such as food, mineral, polymer and chemical.
Benefits of Flash Dryers:
Cost effective during installation
High efficient thermal power
No need of extra machinery for drying with pneumatic conveying
With additional cage mill crushing of lumps very easy
• Useful for moderately heat sensitive product • Compact and simple design • Most suitable for corrosive liquids
In rising film feed, solution forms a rising film in the tubes. These are unsuited to salting or severely scaling liquids. These evaporators are compact, simple in construction. They are suitable for corrosive liquids.
Evaporators are thermal concentrators. Our industrial evaporators are for concentrating dilute liquids, for increasing solids content & for reducing volume by evaporating water.
Evaporators are based on steam economy i.e. kg of solvent evaporated per kg of steam used. Reusing evaporated solvent as heating medium, higher steam economies are achieved. This method of increasing utilization of steam is used in multi-effect evaporator. In multi-effect evaporator vapour from the first effect is passed over to the next effect in which boiling takes place at lower temperature & pressure.
Thermo-compression evaporator is another alternative to increase steam economy. Vapor of solvent evaporated is compressed & is used as heating medium in the same evaporator.
• Reclusively less expensive • Facilitate easy de-scaling • Can be widely used in sugar industry
Short tube evaporators are the oldest but still widely used. They are most widely used in Sugar Industry in evaporation of cane-sugar juice
They are relatively inexpensive & easy de-scaling. This type is seldom used as a crystallizing evaporator. By installing a propeller, propeller calendria type evaporator can be used for crystalline products. They suffer from mild scaling but can be cleaned mechanically.
We offer single effect or multi-effect evaporators according to product properties & /or clients requirement with or without thermal compression to lower temperatures & reduce residence time of product.
