Dog Chew Production Line ‑ High‑efficiency Pet Treat Extrusion Machinery
2026-08-26
As an innovator in the field of pet‑food equipment manufacturing, Shandong Zhennuo Dog Chew Production Line features core strengths of **high fresh‑meat inclusion, precise cooking and flexible production**, delivering efficient and healthy solutions for pet‑food enterprises worldwide.
1. Full‑process Intelligent Production: One‑stop Operation from Raw Materials to Finished Products
Cooking & Extrusion — Cooling & Shaping — Drying
(1)Extrusion Section: Two‑stage screws realize raw‑material homogenization and high‑temperature sterilization.
(2)Cooling Section: Dual air‑cooling and water‑cooling modes enable rapid shaping to guarantee precise product geometry.
(3)Drying Section: Multi‑layer variable‑frequency drying system reduces energy consumption and ensures uniform and stable moisture content in finished products.

2. Technical Highlights: Four Industry‑leading Breakthroughs
(1)Extrusion System with Large Length‑to‑diameter Ratio
Custom‑designed screws deliver sufficient material cooking and texture adjustment. It solves loose forming caused by insufficient shearing force in conventional equipment, improving product density and greatly enhancing durability.
(2)High Fresh‑meat Inclusion Capacity
Low‑temperature staged cooking technology fully preserves nutrition and flavor of fresh meat while preventing protein denaturation. It meets requirements for natural ingredients in high‑end dental dog chews and achieves notably higher fresh‑meat addition rates compared with competing equipment.
(3)Dynamic On‑line Adjustment Function
Equipped with intelligent temperature control and pressure sensor systems, the production line adjusts extrusion parameters in real time to adapt to diverse formulas and target product hardness. Product specification switching can be completed without shutdown for higher production efficiency.
(4)Pet‑safe Dental‑care Design
Original angle‑optimized dies and stepped drying process eliminate sharp edges to prevent oral injuries for pets. Combined with high‑temperature sterilization and drying, the line realizes both molar cleaning and deodorizing effects.
