Energy-Saving Continuous Dryers provide a significant fuel reduction when drying grains. In the LAW dryer, part of the output thermal energy is recovered again for the drying process, leading to fuel savings of up to 20%.
The LAW Economizer dryer is composed of:
- A buffer zone that separates the two drying zones
Reasons to choose a LAW Energy Saving Dryer
Energy savings:
- The drying column consists of a number of compartments that correspond to the chosen evaporation flow
- The lower part of this column has compartments for multipurpose uses, which can be used both in drying compartments and in cooling compartments
- The movement of air in the dryer is ensured by two ventilation groups
- The first ventilation unit, located at ground level, allows the recycling of insufficiently saturated air at the end of drying, as well as cooling air
- The second ventilation group is located in the upper part of the humid air box and allows the extraction of saturated air
- Pneumatic valve systems allow the regulation of the air flow that passes through the grain
- Medium-pressure axial fans (air flow higher than a centrifugal fan for the same electrical power)
- All fans are equipped with anti-dust cleaning filters
- Two-temperature heating system depending on the height of the drying column
- The columns for supplying hot air and used air (recycling) are insulated with 50 mm thick glass wool
- Insulation of the high temperature air circuit by coated double wall
Safety:
- Safe interior access to the height of the hot air column and used air (recycling) by ladder, in all 3 compartments
- Outdoor access security by stairs with intermediate rest platform and roof access platform
- Operational safety thanks to an automated system with proven operation
- Air circuit safety: recycled air is injected into the hot air out of the combustion circuit
- Combustion safety with a pulsed, non-radiant air burner
