Pet Food Manufacturing: Consistency, Nutrition & Innovation Engineered by PerMix

Pet food manufacturing has evolved into a high-precision science where consistency, nutrition, and food safety define brand success. From kibble and treats to plant-based meats and pâté, every formulation requires controlled mixing, hydration, and coating. That’s where PerMix delivers an edge — designing sanitary, high-efficiency mixing systems that ensure perfect texture and nutrition in every batch.


The Challenges of Modern Pet Food Manufacturing

1. Moisture & Texture Control

Pet food formulations span a wide moisture range — from 5 % dry kibble to 75 % moist pâté or meat analogues. Each demands specific shear, dwell time, and heat control. Over-mixing destroys structure; under-mixing creates uneven texture and nutritional hot spots.

2. Protein & Ingredient Diversity

Pet foods blend meats, plant proteins, vitamins, and minerals with very different densities and flow properties. Achieving a uniform blend without segregation requires mixers that maintain precise shear control and batch consistency.

3. Fat & Oil Coating

Flavour, palatability, and aroma come from post-extrusion fat and oil coating. Too little coating reduces flavor; too much causes rancidity and short shelf life. Controlled spraying and even distribution are critical.

4. Hygiene & Allergen Control

Multiple SKUs — including grain-free or allergen-free formulas — share the same plant. Equipment must allow fast washdown or full Clean-in-Place (CIP) to prevent cross-contamination and microbial growth.

5. Process Integration

Manufacturers want seamless systems — loading, mixing, drying, coating, and packaging — all automated for speed, consistency, and traceability.


How PerMix Answers the Need

Twin-Shaft Paddle Mixers for High-Moisture Blends

PerMix PFB Twin-Shaft Paddle Mixers create a “zero-gravity” fluidized zone that blends meats, slurries, binders, and flavor additives in seconds.
Advantages

  • Rapid, homogeneous blending with minimal shear.
  • Uniform moisture distribution across high-protein or meat mixes.
  • Optional liquid additive nozzles for fats, oils, or gravies.
  • Jacketed heating & cooling for thermal control.
  • Built in 304 / 316 stainless, fully sanitary and CIP-ready.

Ribbon Mixers for Dry Kibble & Premixes

For dry powders, vitamins, and premix bases, the PerMix Horizontal Ribbon Mixer ensures precise, repeatable results at high throughput.
Key Features

  • Gentle, efficient blending of grains, proteins, and supplements.
  • Smooth-welded sanitary construction and quick-release covers.
  • Pneumatic or screw discharge directly to extruders.
  • Optional load cells for gain-in-weight batching.
  • ATEX/ExP designs for dust-sensitive operations.

Plow Mixers for Rapid Hydration, Coating & Uniformity

PerMix Plow Mixers (PTS) are ideal for fast, uniform mixing of powders, seasonings, and partially hydrated materials — including plant-based proteins and fibers.
Why They Excel

  • Short blend times with outstanding dispersion.
  • Liquid spray lances for oil, palatant, or emulsion addition.
  • Choppers to de-agglomerate sticky or fibrous ingredients.
  • Easy discharge and full access for CIP.
    Applications
  • Kibble base blending and seasoning.
  • Hydrating pea or soy proteins for plant-based treats.
  • Uniform vitamin and probiotic distribution.

Sigma (Z-Blade) Mixers for High-Viscosity Doughs & Plant-Based Meats

When your mix behaves like a paste or dough, the PerMix Sigma Mixer (PSG) is unmatched.
Advantages

  • Handles ultra-viscous formulations for meat analogues and pâté.
  • Low-speed, high-torque kneading prevents overheating.
  • Vacuum option for deaeration and better density control.
  • Extruder discharge for sealed, hygienic transfer to fillers.
  • Washdown or CIP-ready with full PLC/HMI recipe control.
    Applications
  • High-moisture meat or plant-based loaves.
  • Fat-rich pâté bases needing structure without phase separation.

Vacuum Paddle Mixers & Dryers for Moisture Reduction

For semi-moist pet foods or meat slurries requiring dehydration, PerMix Vacuum Paddle Mixers/Dryers combine drying, cooling, and mixing in one unit.
Benefits

  • Gentle, uniform drying under vacuum.
  • Condensate recovery to control odor and emissions.
  • Tight moisture specification and fast cycle times.
  • Fully jacketed and polished for sanitary operation.

Inline Emulsifiers & High-Shear Mixers for Wet Pet Foods

PerMix Inline Emulsifiers create fine, stable emulsions for gravy, sauce, and pâté systems.
Features

  • Rotor–stator technology for uniform fat dispersion.
  • Continuous mixing inline with canning or filling.
  • Improved texture, gloss, and shelf stability.

Coating Systems for Palatability & Shelf Life

PerMix coating technology ensures consistent flavor and nutrition on every kibble:

  • Vacuum coaters for deep liquid absorption.
  • Spray manifolds for accurate fat and palatant dosing.
  • Integration with loss-in-weight tanks and PLC control for perfect repeatability.
  • Hygienic design for quick cleaning and allergen control.

Safety, Hygiene & Compliance

PerMix designs all mixers for EHEDG, CE, and UKCA compliance. Surfaces are fully polished, crevice-free, and available with:

  • CIP or air-assisted dry-cleaning options.
  • Steam-in-place sterilisation.
  • Explosion-proof and ATEX configurations for dust zones.
  • Full documentation for validation and audits.

FAQs

Q: Which mixer is best for high-moisture pet food?
A: The Twin-Shaft Paddle Mixer ensures even blending of meats and slurries without damaging proteins or emulsions.

Q: How can I hydrate plant proteins without clumping?
A: The Plow Mixer with liquid lances and choppers disperses water or oil evenly for lump-free hydration of pea, soy, or potato proteins.

Q: When should I use a Sigma Mixer?
A: Choose Sigma (Z-Blade) when the material becomes a viscous dough — such as pâté, loaf, or plant-based meat analogues — and needs structure development.

Q: Are PerMix mixers easy to clean between recipes?
A: Yes. Sanitary design, smooth welds, quick-access covers, and CIP options make cleaning fast and verifiable.

Q: Do you provide full systems?
A: PerMix and partner brand Fuxion MME supply complete turnkey systems for ingredient handling, dosing, coating, and packaging.
