To a certain degree；
Step 3：It is mixed, the raw material screening of step 2 is handled, keep after material is in the same size mix stirring
It mixes；
Step 4：Dry and wet matches, and the material of the mixing of step 3 is carried out dry and wet proportioning, reaches ideal preparing granular
State；
Step 5：The drying of raw material, raw material substantially moisture content or bigger in recycling, needs to enter drying work
Duan Jinhang drying and processings；
Step 6：Material blown afloat inside dryer so that full of in entire drying roller, then by wind turbine twitch hot wind into
Enter, increase material and dry air contact area, accelerates moisture evaporation；
Step 7：Raw material compression moulding, raw material water content after passing through drying is moderate, is passing through biomass
It can be molded when grain machine compressed granulate fuel without adding any additive, produce the smooth glossiness granular fuel in surface.
As a preferred technical solution of the present invention, including following percentage：Stalk length 4-6cm, secondary when crushing
Grinding particle size is less than 5mm, raw material moisture 15-25%, moisture 8-10% after drying.
As a preferred technical solution of the present invention, the drying of raw material, due to raw material in recycling substantially water
Part or it is bigger, raw material can be dried if it is the user of macro-organism matter granulator, small processing just needs to dry in the air
It shines, the moisture content general control of raw material is between 15%-25%, if the excessive easy ring for blocking biomass granulation machine of moisture
Mould.
As a preferred technical solution of the present invention, drying machine outlet temperature, the temperature to cyclone separator needs
70 or more temperature, if temperature reach aridity or not enough if plus airborne dust plate and X raise plate to increase dispersion and reduce sawdust
Speed.
As a preferred technical solution of the present invention, material is blown afloat in drying roller, and wind turbine is twitched hot wind and entered, and accelerates
Moisture evaporation, improves production capacity, and drying capacity can reach drying when falling moisture/1-6 tons.
As a preferred technical solution of the present invention, conveying material link increases sub-material, charging and dust-extraction unit, in core
Center portion point increases maintenance point so that the raising of mechanization degree substantially reduces recruitment.
Compared with prior art, the beneficial effects of the invention are as follows：The main purpose of drying is to adjust the moisture content of raw material, is made
Its stable uniform is suitble to granulation machining, and during pelletizing forming, on the one hand suitable moisture can transmit the pressure of pressure roller
On the other hand power can play the role of lubricant, auxiliary particle is filled mutually, to promote raw material to be molded, but moisture content mistake
When big, moisture is easy to form separation layer between particles so that interlayer can not combine closely, and the particle of extrusion is easy expansion and dissipates
It opens, cannot be molded, therefore it is particularly important in process to control suitable moisture content of the raw material.
