Biomass dosing technology

Versatile application possibilities


The strengths of our screw conveyor technology at a glance:

  • Delivery rate up to 50 m³/h
  • lined with wear-resistant bearing plastic
  • all parts in contact with the product are made of stainless steel
  • continuous delivery rate
  • according to ATEX-guidelines

Product specification

The intake and dosing are optimally matched to the mixing technology in the fermenter. The vertical screw conveyor also serves as a support for the fermenter screw, which is important for fermenters whose walls cannot bear any mechanical loads.


Special characteristics

Screw technology

The advantage of vertical conveying is that the screw element floats in the conveying substrate and does not touch the side walls. The special design of the screw tube prevents the substrate from winding and ensures uniform transport into the fermenter. The screw technology in the EX area complies with the ATEX directives. Durable and robust screw drive technology with parallel shaft gear motors.

 
Feeding technology to a crusher mill

Assembly-friendly system technology, as the pre-assembled screw systems can be set up ready for operation in just a few hours. The screws are available in steel, V2A and V4A.

Equipment variants and accessories

Wall feed-through

Wall feed-through

The feed-through dips into the substrate in the fermenter underneath the fill level, thus ensuring that no gas can escape, even when the fermenter screw is disassembled. What sets our system apart is that the fermenter screw can be disassembled even when the fermenter is full.

Steep conveyor screw

Steep conveyor screw

The special design of the auger tube prevents coiling of the substrate and ensures uniform transport into the fermenter. Durable and robust screw drive technology with flat gear motors.

Screw technology up to 20m height

Screw technology up to 20m height

Double-section steep screw design for filling fermenters of up to 20 m height. Assembly-friendly system technology, as the pre-assembled screw systems can be set up ready for operation in just a few hours.
