Design and manufacture of biomass samplers

Tailor-made and manufactured in our workshops, our biomass systems are suitable for sampling from moving-bottom lorries, chain conveyors or conveyor belts.

Biomass sampler with one rotating arm

Removal of chips, pellets or other materials during the emptying of the moving floor lorry.

Sampler adaptable to a gravity chute for powder or granules.

Staff safety during the operation.

Préleveur biomasse à bras rotatif

Principle

A mobile trough of a size adapted to the desired quantity is fixed to the end of a rotating arm. The sample is taken at the end of a conveyor belt. The trough is positioned under the product flow and then emptied into a recovery tank for the accumulated samples. The equipment can be adapted to suit the conditions of use.

How it works

An electrical control box equipped with a touch-sensitive display and a PLC enables :

  • Ensure and secure the operating cycle.
  • Set the number of sampling cycles
  • Set the frequency of sampling

Equipment

All components are made from materials suited to the product and operating conditions (generally painted steel).

Biomass sampler two rotating arms (fixed)

Removal of chips, pellets or other materials during the emptying of the moving floor lorry.

Staff safety during the operation.

Principle

A mobile trough of a size adapted to the desired quantity is fixed to the end of an arm with two joints. The sample is taken when the truck begins unloading. The trough is positioned under the product flow and then emptied into a recovery tank for the accumulated samples. The equipment can be adapted to suit the conditions of use, depending on the number of pits.

How it works

An electrical control box equipped with a touch-sensitive display and a PLC enables :

  • Ensure and secure the operating cycle.
  • Set the number of sampling cycles
  • Set the frequency of sampling
  • Choosing the pit

Equipment

All components are made from materials suited to the product and operating conditions (generally painted steel).

Biomass sampler with two retractable rotating arms

Removal of chips, pellets or other materials during the emptying of the moving floor lorry.

Staff safety during the operation.

Principle

A mobile trough of a size adapted to the desired quantity is fixed to the end of an arm with two joints. The sample is taken when the truck begins unloading. The trough is positioned under the product flow and then emptied into a recovery tank for the accumulated samples. The equipment can be adapted to suit the conditions of use, depending on the number of pits.

If a grapple is used, this version of the sampler frees up the storage area.

How it works

An electrical control box equipped with a touch-sensitive display and a PLC enables :

  • Ensure and secure the operating cycle.
  • Set the number of sampling cycles
  • Set the frequency of sampling
  • Choosing the pit

Equipment

All components are made from materials suited to the product and operating conditions (generally painted steel).

Cross sampler on conveyor belt

Sampling of agglomerates, aggregates, powders, granules and forestry chips at the belt jetty. Designed for use under piers up to 3 metres wide.

The principle behind this system is to ensure representative sampling.

Principle

A mobile trough moves at a set speed under the full width of the product throw and evacuates the captured sample:

  • Either continuously in a refocusing sampling hopper.
  • Or at the end of the stroke, when the trough is capable of receiving the entire sample before being emptied.

Each levy is proportional:

  • The flow rate, the opening of the trough and its speed of passage under the flow.

How it works

A control panel is used to run a sampling cycle (which may include one or more passes under the flow). The equipment can be used to programme and count samples at regular or variable intervals.

This equipment enables representative samples to be taken.

Equipment

All components are made from materials suitable for the product to be sampled, such as steel or stainless steel. The design is particularly robust. The dimensions and configuration of the system depend on the layout of the installation.
