Sigma blade mixer

in-linebatchsolid/liquid

Product Overview
The Sigma mixer for dog food is designed to mix and knead high‑viscosity dog and pet food formulations. It is optimized for meat‑rich and semi‑moist recipes and achieves rapid, uniform mixing and plasticization through opposing double ∑‑shaped blades and a high‑shear kneading action.

Applicable Dog Food Product Types

• High‑meat content soft dog food
• Semi‑moist dog food
• Functional pet food base ingredients
• Treat gum base and premixes

Key Benefits

• 1. Powerful kneading capability: Opposing double ∑ blades deliver strong squeezing and shearing for effective processing of high‑viscosity, plastic materials.
• 2. Uniform mixing: Repeated squeezing and folding ensure thorough dispersion of meat, starch and additives.
• 3. Temperature control: Jacketed heating/cooling limits temperature rise during mixing to protect sensitive ingredients.
• 4. Hygienic, easy‑to‑clean design: Rounded internal corners reduce residue and simplify cleaning operations.

Function & Typical Use
The mixer is typically used as a front‑end pre‑mixer or as a high‑viscosity base preparation unit prior to downstream molding, extrusion or drying processes. It is suitable for producing semi‑finished bases and feed blends requiring intensive kneading and homogenization.
