Preparing animal by-product streams for
consistent processing

Milling and homogenization support the preparation of animal by-product streams before thermal treatment, rendering, separation, or further processing. The goal is to create a more consistent material flow that can be handled, heated, and processed more reliably. In animal by-product projects, the right preparation concept depends on raw material type, particle size, moisture content, fat content, variability, and the requirements of the downstream process.

What is milling and homogenization?

Milling and homogenization refer to the mechanical preparation of animal by-products to reduce size differences and create a more uniform material stream. In practice, this may be connected to size reduction, shredding, mixing, pumping, sterilization, rendering, or separation. It is not an isolated process step: it must be designed around the full processing line and the expected output quality.

Why milling and homogenization matters

Uneven material streams can make processing harder to control. Large particles, mixed textures, or inconsistent moisture and fat distribution may compromise heat transfer, process stability, energy consumption, separation, yield, and final product quality. A well-designed material preparation concept supports more predictable thermal treatment, better integration with downstream systems, and more stable industrial operation.

How WALDT can help

WALDT is a specialized engineering and technology partner for animal by-product processing projects.
01

Assessment

We start by understanding the raw material stream and the downstream process requirements.

  • Raw material type, volume, and variability
  • Particle size and material consistency
  • Moisture, fat, and solids content
  • Pumping, conveying, or mixing requirements
  • Target outputs and quality expectations
  • Site conditions, utilities, and operating constraints
02

Technology Study

A Technology Study can define the technical basis for milling and homogenization within the full processing concept.

  • Raw material and target output assessment
  • Particle size reduction and preparation requirements
  • Mass balance calculations
  • Process concept development
  • Yield, energy consumption, and product quality assumptions
  • Site, layout, and utility requirements
  • Total cost of ownership considerations
03

Integrated process design

WALDT helps connect material preparation with the wider animal by-product processing system.

  • Material intake and preparation logic
