2, according to the way into the wind: down ventilation, upward ventilation, composite ventilation type.
3, according to the exhaust way points: a counter-current exhaust, and the flow of exhaust, separate exhaust type.
4, sealing: low ventilation resistance and high ventilation resistance.
Adapt to the drying of the material has some limitations. The structure is much more complicated than the drying box.
Hot air circulation oven is a kind of intermittent drying equipment
This type of drying equipment only two: First, parallel flow pattern; then there is ventilation flow pattern.
Adapt to the drying of the material more. Equipment structure is simple; but the drying time is long; labor intensity, dry material out of uniformity as ribbon.
