DRYER

Introduction:

The tower-shape dryer is specifically used to dry agricultural products. The system uses horizontally parallel inverted V-formed channels of “distributing hot air” and “discharging humid air” so as to keep hot air passing through the material and to take out waste water. Humid air, after passing through the dust filters, will be discharged out of the system; the waste air, therefore, will certainly be clean and friendly to the natural environment. The heat supplied to the system can be taken directly from a husk furnace, charcoal burner, oil burner... or indirectly from a boiler with a radiator, etc.

There are two types:
1- Batch drying:
The system includes a drying section and a holding section. The maximum amount of material dried in batch is the same capacity of the dryer.
2- Continuous drying:
The system includes only a drying section. It is connected to material conveyors, holding tanks and possibly to the second dryer.

Features:
- Usually used with fresh rice after harvest (with initial moisture content above 16%).
- The dryer helps fresh rice reach the standard moisture (14% - 15%) before being put into the peeling process.
- There are 2 basic types of drying: Horizontal drying (Traditional) and Tower drying (Batch drying and Continuous drying).
