A new fluid bed dryer and cooler uses a fraction of the energy of a
standard machine, claims its manufacturer.

The huge jump in energy prices over the past 18 months has driven processors to search for more efficient machines that can save them costs. Ventilex's Ventura 130 is capable of delivering the same drying capacity as a standard fluid bed dryer while using less energy, the company claimed. The machine is designed to capture and re-use almost all of the latent heat. For most products with a 4 per cent moisture content and above, the Ventura 130 will use about 1,200 British thermal units (BTU) per pound of water evaporated, or less, the company claimed. The higher the input moisture, the lower amount of btus are used per pound of water evaporated. The company calculates that the design cuts energy use by 60 per cent compared to a typical rotary dryer system. Energy use is about 35 per cent less than all other known fluid bed dryer systems, the company claimed. The Ventura has two exhaust air streams. The one off the cooling section is at 110 F, and the one off the heat exchangers/heat recovery units is 95 F degrees. The lower the exhaust air, the better use of the energy.
