The coffee grounds dryer can be used to process waste coffee
grounds from coffee factories. The dried coffee grounds can be used
as biomass pellet fuel. The coffee grounds dryer is also suitable
for wood chips, wood flour, brewer's grains, cocoa residue, etc.
Process flow of coffee grounds dryer:
Raw material → feeder → heat source → dryer → discharger → induced
draft fan → cyclone unloader → water bath dedusting and deodorizing
device → waste gas exhaust and power distribution cabinet.
Working principle of coffee grounds dryer:
The heat source of the coffee grounds dryer comes from the
supporting combustion device, and the dryer adopts a downstream
heating method. The coffee grounds enter the barrel from the
feeding device, and are pushed backward by the spiral flight board.
Due to the inclined placement of the dryer, on the one hand, the
material flows to the rear end under the action of gravity and
rotation; on the other hand, the material is repeatedly picked up
by the lifting board, brought to the upper end and then
continuously sprinkled down, so that the material forms a uniform
curtain in the cylinder. , to fully exchange heat with the hot air
in the cylinder, as the material is repeatedly scattered, the
moisture contained in it is gradually dried, so as to achieve the
purpose of drying.
Features of Hengyang coffee grounds dryer:
1. The self-insulation thermal efficiency of the cylinder is as
high as 70% (the thermal efficiency of the traditional single
cylinder drying is only 30%).
2. The tail transmission is adopted, and the transmission is more
stable and reliable; it completely changes the phenomenon that the
supporting wheel often slips and affects production.
3. Compared with the single cylinder dryer, it occupies about 50%
less land, about 50% less civil construction investment, and 60%
less power consumption.
4. A variety of circumferential lifting materials are combined and
distributed to effectively control the drying time and achieve a
good drying effect.
5. The desired final moisture index can be easily adjusted
according to user requirements.
6. The material flow is controlled by frequency conversion, and the
desired final moisture index can be easily adjusted according to
user needs.
7. The whole system is equipped with material blocking alarm and
anti-riot device.
