7.5kW Multi Bend Pipe Hot Air Stream wood chip drying systems

Product Specification

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.

Features of hot air stream wood chip dryer

1. 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.
2. 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.
3. 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.
4. 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.
5. Short drying time, suitable for heat-sensitive materials, the finished product is not in contact with the outside world, no pollution, good quality.
6. 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

1. Check the automatic drain valve on the pre-filter before each shift every day.
2. Check the normal operation of tower changing and pressure boosting.
3. Check the operating conditions, inlet pressure, inlet temperature, and air flow.
4. Check the moisture indicator, blue means dry, and pink means wet.
5. 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.
6. Check the pressure drop of pre-filter and rear filter, if the pressure drop is over 0.5 bar, replace the filter element.
