Continuous dryers with overhead conveyor
This type of dryer is specially designed for use with an overhead conveyor. This is especially advantageous when you need to save space by hanging the batch or when you simply cannot place or support the batch.
It is a continuous dryer. The batch therefore enters at one end and leaves the dryer at the other. To minimize losses at the open ends of the dryer, we are able to supplement the device with sliding or swing doors that are only open for the necessary time during the movement of the conveyor. Heating and circulation of the oven are ensured by fan units placed on the ceiling of the oven, the dryer can be equipped with thermocouples or non-contact temperature sensors to monitor the temperature of the batch.
Dryers can be multi-zone and, like continuous dryers with a belt conveyor, the movement of the overhead conveyor can also be coordinated with regulation in individual zones in order to achieve the desired temperature profile on the batch. One possible option is to use a gravity conveyor to move the furnace charge. Individual hangers are discharged from the furnace at a set time interval.
