Processing of mixed waste from poultry slaughtering

In the traditional processing of waste, the mixed waste is collected, sterilised and hydrolysed. In this way, the raw material is processed  into meat bone flour with high fat content. In the next step the fat is extracted from the meal, which is then packaged. The fat is filled separately. Both final products are used as feed additives.

Example layout plan:

1. Processing of separated waste from poultry slaughtering. Here, the waste is collected and processed according to kind and type.

2. Processing of waste from large animal slaughtering

Layout examples

  • Silo
  • Screw conveyor
  • Batch cooker
  • Metal detector
  • Cooling track
  • Grinding system with meal weighing and filling into sacks
  • Exhaust air cleaning and bio-filter unit
  • Connecting pipes, electrical cabling and system switch cabinet

Depending on requirements, these systems are adjusted or even expanded. We offer for you complete project planning according to the building specifications, the supply of equipment and assembly supervision, as well as commissioning and the training of your personnel. For this purpose, our reliable partner is HAARSLEV a/s.

Organic and slaughterhouse waste

Organic and slaughterhouse waste are processed by means of a batch procedure, the raw materials are pre-mixed in the raw materials container and transported to the boilers by means of conveyors.

The batch cooker is the main component of the waste processing plant and serves the following purposes:
Sterilisation, hydrolysation and drying of wastes. Delivery as a complete assembly group with TÜV (Technical Control Board) acceptance.

Organic and slaughterhouse waste are processed by means of a batch procedure, the raw materials are pre-mixed in the raw materials container and transported to the batch cooker by means of conveyors.

Here, the slaughterhouse waste is cooked by means of a batch procedure, the dry mass is then separated from fats and processed to produce feed meal. The photo shows a dry melting system with 2 boilers, each with 5,000 kg batch output.

Fat processing
