PELLET MACHINE mod. N-MIDI-B – With inverter of drawbench motor – As per E.C. rules (output 500/700 kg/h)
The pellet machines MIDI allow to obtain a constant high quality pellet production, that – according to the raw material (that determines either the quality or the quantity of the produced pellet) – will allow you to obtain the “DIN PLUS” certification for the final quality of your wooden pellet and, therefore, to sell the same to the users of the household market as well as to the users of the industrial market.
Furthermore, the MIDI pellet machines develop a production ratio like 18 kg. of pellet per each installed kW on the machine, improving competitive performances.
Besides pellet machines, even the machines of the pellettizing installation were conceived in order to guarantee the final user a pellet production of high saving of the installed/consumed energy, obtaining a further lowering of the industrial cost of your pellet and, therefore, competitive advantages in the market of the sale of combustible pellets.

Information about general typologies of theinput materials in the pellet machine:
♦ Morphology: sawdust or material with granulometry not less than 0.5 mm. and not more than 1.5 mm.
♦ Humidity ratio: between 8% and 14% at the most
♦ Features: all types of wood or other materials, free from ferrous material
Innovative features of the MIDI pellet machine (as to the pellet machines developped by the fodder sector):
– Enbloc structure and feeding system that derive from the patented technology of the PLUS pellet machine
– no use of additives or bonding agents, even of animal origin
– high energetic class motors controlled by inverter (ENERGETIC SAVING)
– sawdust loading in the compression drawplate through an only central screw
– presser rolls: not overhang ones, but hooked to the structure of the pellet machine
– hydraulic gearcase for lubrication of presser rolls and chuck
– adding by vegetal oil for working cycle start and end (in order to avoid hardening of the remaining material in the compression circuit when the machine doesn’t work)
– reduced encumbrance
– reduced cleaning and maintenance times thanks to the direct opening of teh pelletizing zone and the quick tool replacement
– Pellet machine with mechanical and electric working system
– Control and management by means of programmed logic systems
– Manual adjustment of presser rolls (that allow the rotation of the compression drawplate)
– Material loading system through an inox steel tank and a batching screw adjusted by an inverter, that is controlled proportionately to the working couple of the compression screw
– Compression holes of the drawplate = mm. 14-50 long, variable according to the material that must be worked (sawdust or other vegetal/agricultural wastes)
– Front pellet evacuation
– Min./max. level indicator on the loading tank of materials
– Automatic motor greasing controlled by PLC
– Grease lubrication of presser roll and chuck
– Safety electric lock of the opening door of the drawplate and presser rolls
– Protection carter of motor belts
– Lifting sockets for truck on theground
– Prearrangement for connection of dust and steam suction intakes
– Use and maintenance handbook and E.C. marking
General features of infeed materials:
– Morphology: sawdust or material with granulometry not less than 0,5 mm. and more than 1,5 mm.
– Humidity ratio: included between 8% and 12% at the most
– Features: pure material (free of ferrous material or other if different from the main one)
All models include electric board ans a group of tools (to be considered like expendable materials) composed by: nr. 1 compression die plate and nr. 2 presser rolls. Such mechanical parts are fundamental for pellet production, for this reason the machine must be equipped – according to the type of wood to be processed – with the proper die plate and the consequent couple of rolls.
Therefore for each sypply it’s required to send a sample of material to be reduced into pellet in order to determine the suitable tools for customers.
