Rendering for poultry operations
Turn the by-products from your poultry processing — carcasses, bones, offal, feathers, fat and blood, none of it intended for human consumption — into proteins, minerals and oils you can sell. Haarslev helps you recover that value with equipment, automation and service support built for steady operation.
Talk to our teamPoultry processing produces three very different by-product streams — meat, bones and offal; feathers; and blood — each with its own processing requirements and its own end-markets.
We configure rendering lines around each of those streams, so you recover the maximum value from every kilo: higher end-product quality, lower energy use per tonne, and meal and fat grades that open up better-paying markets in pet food, aquafeed and livestock nutrition.

Whatever comes off your line, there's a route to a commercially valuable product.
Here's how we help you get there — by output stream.
Meat, bones and offal→ poultry by-product meal and fat
Your meat, bones and offal become poultry by-product meal (PBM) and poultry fat — high-protein, highly digestible ingredients valued in pet food, aquafeed and broiler diets.
Continuous dry rendering
A reliable, high-capacity process that keeps your operating costs low.
Batch dry rendering
A versatile route for handling all of your raw materials, well suited to lower volumes and to sterilisation requirements.
Continuous pre-cooking and batch sterilisation
High evaporation capacity, with less need to reduce particle size first.
Continuous low-temperature wet rendering
Reduced steam consumption and lower operating costs, with better quality in both your meal and your fat.
Dewatering using waste heat
More dewatering capacity for less energy, and with less environmental impact.
Equipment
Feathers→ feather meal
In hydrolysis, keratin-rich feathers are broken down under heat and pressure into a digestible protein. With direct hydrolysis, steam is injected straight into the material for fast, even heat transfer. With indirect hydrolysis, heat is transferred through the vessel wall without direct steam contact, producing a drier product that is more economical to dry downstream. After hydrolysis, the material is dried, typically in a Haarslev disc dryer or ring dryer, into a stable, storable feather meal: a valuable, high-protein ingredient for animal feed. Higher digestibility earns a higher price, so the process you choose has a direct effect on what your meal is worth.
Batch hydrolysation
Straightforward and reliable, normally best for low-to-medium-capacity operations.
Continuous indirect hydrolysation
A continuous process suited to medium-to-high capacities.
Continuous direct hydrolysation
An energy-efficient, medium-to-high-capacity process. Add evaporators to lift yield further and improve feather-meal quality.
Equipment
Blood→ blood meal
Your poultry blood — typically 16–18% protein solids — becomes blood meal: a high-lysine ingredient for non-ruminant feed, or a nitrogen-rich fertiliser for higher-value markets. Removing more than half the water mechanically, before any drying, keeps the energy cost down.
Coagulation and dewatering
Steam-injection coagulation followed by mechanical separation takes out the bulk of the water before drying.
Continuous drying
Gentle, controlled drying that protects protein quality.
Premium spin-flash drying (IDX)
For high-digestibility blood meal that commands a premium price.
