Tunnel Drying Equipment

Tunnel Drying Equipment

Tunnel Drying Equipment Introduction:

(1) The Tunnel Drying Equipment is one kind of batch, tunnel type continuous production drying equipment.

(2) It is mainly used for better breathability slice, strip and briquettes and bulk material, like coal bar, coal tablet, etc. drying process.

(3) Heating source is power, steam and hot air, etc. The Tunnel Drying Equipment is conceptually very simple. Product is carried through the dryer on conveyors and hot air is forced through the bed of product.

(4) Tunnel Drying Equipment is often described as simply a conveyor in a box with hot air. The reality, however, is that the belt dryer is one of the most versatile dryers available.

(5) Few drying technologies can match the belt dryer’s ability to handle such a wide range of products.

Tunnel Drying Equipment Features:

(1) Tunnel Drying Equipment feeding part has feeding device, which laid material evenly on the mesh belt through distributor. When first layer move to driving chain wheel, material fall down to second layer by self-weight.

(2) Use blower delivery hot air to bottom from upper both wall side inter-layers, make hot air flows up from bottom, so that wet material fully absorb heating, and reach to perfect drying effect.

(3) The wet air from dried material is transported by weep hole on the upper middle part of dryer. Not dried briquettes, the strength is a little bad at the beginning. When fall down from layer to layer, the impacting and rubbing of each briquette will bring powder.

(4) Traditional drying machine get manual clean, but it takes big labor intensity, and need open door to clean, which cause drying machine inside temperature lose.

(5) Now, our factory adds a scraper slag removal machine on the dryer bottom can get rid of powder quickly and conveniently.

Tunnel Drying Equipment Advantages:

(1) Materials are uniformly put on the mesh-belt by the feeder.

(2) The drier is composed of several units.

(3) For each unit, the hot air is circulated separately.

(4) Some exhausted gas is discharged with a special moisture elimination blower.

(5) The waste gas is controlled through an adjustment valve.

(6) The hot air passes through the mesh-belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the heat and mass transfer process.

(7) This process will bring the material water away.

(8) The mesh-belt moves slowly, Running speed can be freely adjusted according to the material temperature. The final products after the drying will fall into the material collector continuously.

(9) The top and low circulation units can be freely equipped according to the users' demand.The unit number can be selected according to the demand.
