Tube Dryer

SFE tubular dryers are widely used in the preparation of special flours. Typical applications include:

• Heat treatment and moisture reduction of flours for soup thickeners.
• Enzyme activation.
• Treatment of special flours to prevent infestation and give long shelf life.
• Treatment for flour products for industrial use.
• Treatment of biscuit and cake mixture flours.

Lowers labor and operational costs and simplifies material handling. The drying material is uniformly agitated and flows through the drum at the rate fixed for efficient drying of the particular material.

Achieved through the efficient transference of heat through the product with optimum use of heating surfaces plus the ease of operation and low maintenance cost.

The product of experience enables operating and maintenance costs to be kept at a low level. The robust construction gives the equipment a long and economical working life.

These units are constructed to meet the particular requirements of the process industry and the nature of the processed material, such as treatment of corrosive material, high quality food, chemical and pharmaceutical products, etc.

Drying is effected by a concentric revolving reel of parallel tubes, charged with live steam. The wet processed material is fed in at one end of the machine and passes over and amongst the tubes, at the same time being conveyed at a measured rate until discharged in a dry state at the opposite end. It is a continuous process. Simon coolers are of similar design with a coolant replacing steam in tubes.

The heating (or cooling) element known as the tube reel comprises high grade steel tubes rigidly held between substantial endplates, each endplate being fitted with a cast steel, fabricated steel, or suitable alloy header which is designed to facilitate the flow of steam or coolant, and the removal of condensate through trunnions. The distributing and conveying elements are placed around the periphery and along the length of the reel.

The materials of construction are chosen to meet each particular application.

The dryer or cooler casing is of robust construction, in a variety of materials to suit the application and is thermally efficient.

For better performance and ease of maintenance, outboard roller bearings are used.

Additional features which can be fitted as required are drop bottom doors to facilitate cleaning, and built-in expansion chambers to reduce fine dust carry over in vapour extraction systems.
