Making sure there is no water left in the input material is crucial prior to fat separation. This makes an effective cooker vital for any batch-based dry rendering process to operate profitably.

The Haarslev Batch Cooker is a straightforward, quickto-install unit that you can bring on line quickly for the cooking, pressure cooking, hydrolysis or drying of an exceptional range of animal and poultry by-products. These include mixed meat offal and bones, poultry offal and wet feathers.

It can operate at the 133°C temperatures important for sterilization, and is ideal for smaller-batch processing of particularly large particles (up to 50mm) – which helps cut back on pre-cooking crushing requirements.

Furthermore, this solidly engineered, well-proven cooker can operate under pressures of up to 5 bar, ensuring your processing setup complies with the 2009/2011 EU Animal By-products Directive and can even process inputs containing hair, wool or feathers, for use in pet food.

A Haarslev Disc Dryer is the ideal solution for removing as much water as possible, as gently as possible, from coarser fish, animal or poultry by-products with a low fat content.

Designed to use steam pressures of up to 10 bar, these dryers have become the solution of choice for coarser inputs featuring lower fat levels, because they make use of the natural fatty content in the material.

These sturdy, reliable units are built around a rotor consisting of a central shaft fitted with multiple steamheated discs. These apply indirect heat over a very large area, in a compact design that quickly and effectively removes the evaporated water vapor. This means as much heat as possible gets transferred to the material in the dryer.

The dried material is discharged at the bottom, using a screw conveyor fitted with variable-speed drive. This can be adjusted independently of the dryer itself, providing maximum flexibility. Vacuum drying configurations are also available to provide exceptional end-product quality.

The Haarslev Fat Screw Press provides highly effective mechanical extraction of the fat content from cooked and dried animal and poultry by-products, in a continuous flow. This enables you to achieve a hard cake with a low fat content.

The new Fat Screw Press is based on the wellproven HM3000 screw and cage design.
It comes in a new hygienic design with several improvements making installation and service easier.

Among the major improvements are the newly developed pat. pending cage open assist as well as the optional pat. pending automatic cage cleaning system.
This new press is available both with or without a hydraulic choke. It also has a modular drive setup where the main motor can be fitted on either side or on the top of the press.

The Haarslev Spin Flash Dryer System is a straightforward, reliable milling and air drying system that enables you to maintain the integrity of the highvalue protein chains in coagulated animal blood.

This fully automated EU standards-compliant integration of milling and drying operations differs from the vast majority of comparable installations by carrying out the milling before the drying. This maximizes thermal transfer between your inputs of coagulated blood and the surrounding 220oC air.

This means that the moisture content flashes off within one second, ensuring gentle, swift treatment of the protein chains that are essential for good meal digestibility and high commercial value.
