Two parallel straw pellet production lines:
Straw transport and grinding,
transport of ground straw to the tank,
transport of ground straw to the conditioner and conditioning of the raw material,
dosing straw for steam and ironing with full control of the technological process of ironing,
transport of pellets to the cooler and further to the tank of the finished raw material,
feeding on scales and to the wrappers.
