Beltomatic Configurations

Recycle Heat Model

This model takes advantage of the gradient exhaust temperature produced by the lower air chamber design in all Beltomatic dryers. The most useable exhaust air is identified and recycled for best efficiency. This also produces an air up/air down pattern for gained moisture consistency. This model can be used independently or in combination as the final stage unit in a multiple stage system.

Product is loaded by various spreading mechanisms at the beginning of the conveyor and discharged at the opposite end. There is only one control for product depth. Airflow velocity, resident time, and air temperature can be set to a wide range of adjustments. Normal operating temperatures are from 10°F heat rise to 240°F. Special applications can be constructed for up to 400°F. Air velocity through the bed can be set from 25 fpm to 200 fpm. Normal operating range is 100 to 150 fpm. Percentage of exhausted airflow verses recycled airflow can be altered by the exhaust fan speed.

These models are sold as all heat or heat and cool. Heat from the cool section can be recycled for gained efficiency with certain products. Standard widths are 2', 6', and 8' and standard lengths are in increments of 12". Custom widths and lengths are available.

These models are usually selected for drying of various food and feed products for applications with a small percentage of moisture removal or low final moisture content. This model is also selected for heating and roasting of various food and feed products and as a final stage unit in a multiple-stage/multiple-pass system when a higher degree of controllability and quality is necessary.
