Multi-Bend Pipe Hot Air Stream Wood Chip Dryer Machine Hot air stream wood chip dryer is a continuous, efficient, and fast
solid fluidization drying equipment, which can suspend loose powder
granular material scattered in hot air, and remove water instantly
in the process of air entrainment, and is suitable for drying the
surface water of powder granular material with particle size
ranging from 5μm ~ 0.5mm. The high-temperature hot air in the hot air stream wood chip dryer
flows in the drying tube at a high speed, and the residence time is
very limited. Therefore, it is generally only suitable for the
constant-speed drying process in which the unbound water of the
material undergoes surface evaporation. Practice shows that in the
presence of moisture in these states, granular materials can be
dried in the air-flow drying tube, and a product with a moisture
content of 0.3% to 0.5% can be obtained. As for the wet material
whose moisture content diffuses and migrates in the material, it is
totally unsuitable for the air drying process. Hot air stream wood chip dryer parameter | Model | TYQL-30 | TYQL-40 | | Power (kW) | 7.5 | 7.5 | | Capacity (kg/h) | 800 | 900 | | Big pipe diameter (mm) | 320 | 400 | | Small pipe diameter (mm) | 220 | 320 | | Pipe thickness (mm) | 2 | 2 | | Supply air volume (m3/h) | 9000 | 10000 | | Energy efficiency index | 85% | 85% | | Moisture content of raw materials | 20% | 30% | | Note: customized service is available. |
Features of hot air stream wood chip dryer - Dry intensity, equipment investment province. Air flow drying
equipment to deal with larger, large water evaporation capacity,
and equipment, small volume, investment province, is incomparable
to other drying equipment.
- High degree of automation, good product quality. Drying materials
in the whole process in the pipeline, drying time is very short
(only 2-10 seconds), during this period, the heat is mainly used
for water evaporation, the temperature of the material itself does
not rise much, temperature impact on the product is relatively
small. Therefore, the product does not contact with the outside
world, small pollution, good quality.
- Hot air stream wood chip dryer is supplied in complete sets and the
heat source is free to choose. The basic type is composed of air
filter, heater, feeder, drying pipe, cyclone dryer, cyclone
separator, pulse bag dust collector, fan, etc. The equipment can be
configured according to the material conditions and process
requirements. Users can configure the equipment according to
material conditions and process requirements.
- Heating mode selection, airflow drying equipment has greater
adaptability. Users can choose according to the conditions of the
location of the equipment, can choose electric heating, steam
heating, heat transfer oil heating, coal-fired hot air furnace, gas
hot air furnace, and steam + electric heating and other
combinations of type.
- Short drying time, suitable for heat-sensitive materials, the
finished product is not in contact with the outside world, no
pollution, good quality.
- Basic hot air stream wood chip dryer, suitable for loose, viscous
small powder materials, the viscous need to configure the dry
powder mixing device.
Maintenance of hot air stream wood chip dryer - Check the automatic drain valve on the pre-filter before each shift
every day.
- Check the normal operation of tower changing and pressure boosting.
- Check the operating conditions, inlet pressure, inlet temperature,
and air flow.
- Check the moisture indicator, blue means dry, and pink means wet.
- Check whether the muffler is dirty and clogged, if the backwash
pressure of the regeneration tower is too high, the muffler needs
to be replaced.
- Check the pressure drop of pre-filter and rear filter, if the
pressure drop is over 0.5 bar, replace the filter element.
