In technological collaboration with M/s. NARA MACHINERY COMPANY, JAPAN, KILBURN makes Fluid Bed Dryers and Coolers. These dryers/coolers efficiently dry a variety of chemical, petrochemical, and other materials using the FLUIDIZED BED TECHNIQUE.

Fluid Bed Dryers can be designed as batch or continuous units depending on the customers' needs. Extensive facilities are available for Pilot Plant Tests at the full-featured Test Centre owned and operated by KILBURN Engineering Limited.

All variable parameters can be changed to investigate a substance's drying characteristics and discover the values of significant factors afterward. This data is further complemented with empirical and real-world field data to construct actual equipment.


Hot air is delivered via the distributor plate positioned at the base of a rectangular chamber. Wet material is continually fed in a fixed quantity and spread by dispersing.

The dried product is continually discharged at the overflow outlets once the intended residence period has passed. The exhaust air is vented outside after passing through a dust separation system.

Salient Features

  • An operation can be conveniently controlled by regulating the hot air feed and temperature following the product temperature at the exit.

  • Over and underflow characteristics offer consistent drying of tiny and big-size particles.

  • Products with higher moisture content can also be fluidized and dried since wet feed is mixed with semi-dried products in the chamber.

  • Additionally, the drying chamber can be divided by baffle plates for more even drying.

  • When hot air and solids come into close contact, the heat transfer coefficient is high. As a result, the drying system is small.

  • Rapid heat and mass transfer rates enable high operating temperatures.

  • Due to unique construction features, heat-sensitive products won't overheat. The embedded heat exchanger has distinctive and energy-efficient design.

  • Additionally, the drying chamber can be divided by baffle plates for more even drying.

  • The capital expenses are much reduced

  • Easy adjustments to dried product moisture level and residence duration; simple handling of feed and product.

  • Due to absence of any moving components, the operation is stable, and maintenance is minimal.
