Industrial Dryers

Spray Dryer
SSP Spray Dryers are relatively simple in operation which accept feed in fluid state and convert it into a dried particulate form by spraying the fluid into a hot drying medium.

Feed Atomisation is done using high pressure Nozzle, High pressure Nozzle, High Pressure Air, or two fluid Nozzles. The heating method of drying air can be of either steam coils or thermic fluid or Air Heater according to the service conditions available. The hot air is distributed into the chamber from top by an Air Disperser.

The fines produced are taken out from the top/ centre along with air to a cyclone separator & separated, and the final powder gets collected at the bottom. Additional systems like fines recycling into the chamber for agglomeration, powder cooling, conveying, storage & bagging are optionals.

SSP'S UNIQUE SPRAY DRYER DESIGN ENSURES

• Less wear and tear of atomising system due to absence of any moving parts.
• Flexibility in controlling powder quality and production of instant powders.
• Less down time for maintenance purposes.
• Possibility of expanding capacity upto 100%
• Flexibility of Drying different products in one Dryer.
• Winch Driven special cleaning lift.

Vacuum Band Dryer
It is best suited for continouous drying of temperature sensitive and sugar containing products at low temperature under vacuum conditions. The dryer consists of a vacuum chamber in which conveyer bands of food grade quality are arranged. The band passes over the hot plates heated internally by steam or hot water. Feed product is spread on the moving band and is dried as it moves on the hot plates. Dried product is obtained at the other end

APPLICATIONS

Fruit and vegetables Pharmaceuticals Extracts

Gelatin Enzymes Beverage Mix

Fluid Bed Dryer
Versatile Drying method (Batch or continuous type) used for drying of various types of solids efficiently. It can also reduce the energy requirement of a spray drying plant when used as a second stage dryer for production of instant quality powders.

Fluid Bed Dryer comprises of a top fluidising chamber & a bottom air distribution chamber separated by a specially designed perforated plate.

The feed of wet materials is dried by intimate contact with hot air when the material is in a fluidised state. A vibrating mechanism can be attached to give a forward motion cum agitation to the product at a controlled rate.

APPLICATIONS

Mile Powder Detergents Lactose Agglomerated Powders

Cheese Powder Fruit Pellets Salt

Rotary Dryer
In direct heat Rotary Dryers a continuous feed of wet paniculate material is dried by contact with heated air, while being transported along the interior of a rotating cylinder, with the rotating shell acting as the conveying device and stirrer.

SSP offers Rotary Dryers in co-current and counter current operation. In the former the wet material is exposed to the hottest air which enables heat sensitive or sticky materials to be dried successfully. In counter current operation dried material is exposed to the hotest air helping to achieve very low moisture content. The hot gases may enter at the temperature of 16500 C.

APPLICATIONS

• Ammonium Sulphate
• China clay
• Sodium sulphate
• Citric acid
• Mineral sand
• Effluents etc

Spin Flash Dryer
Spin Flash dryers are ideal for drying of wet cake, slurry, paste which is normally difficult to dry in other Dryers. The material is fed by Screw feeder through a variable speed drive into the vertical drying chamber where it is heated by air and at the same time disintegrated by a specially designed disintegrator. The heating of air may be direct or indirect depending upon the application. The dry powder is collected through cyclone separator/ bag filter or with a combination of both.

APPLICATIONS

• Amino Acids
• Dyes & Dye intermediates
• Pigments etc
• Starch
• Gluten

Steam Tube Dryer
Steam tube dryers is one of the indirect heat rotary dryers, contain rotating shell, rows of steam tubes arranged in concentric circles and extended throughout the length of the dryer.

Steam tubes are designed to transfer heat from steam to the material being dried.

SSP offers tubes with or without fins according the design specifications. The tubes and radial flights together serve to agitate the material.

APPLICATIONS

• Fine dusty particles.
• Maize Germ
• Waste cofee grain
• Grains And Cereals
