EV53 Twin Screw Extruder Barrel | OEM Replacement for Food Extrusion Applications


1. Product Overview

The EV53 Twin Screw Extruder Barrel developed by ZHITIAN is a precision-engineered OEM replacement part designed for food extrusion systems.
This barrel ensures high mechanical strength, dimensional precision, and process stability, meeting the rigorous demands of continuous food-grade extrusion such as snack foods, starch, cereals, plant proteins, and pet food.
It provides reliable extrusion performance without contamination or wear-related failures.

2. OEM-Compatible Precision Manufacturing

Each EV53 barrel is produced based on original equipment drawings and structural parameters, ensuring full compatibility and interchangeability with the OEM extruder.
By utilizing advanced CNC machining, controlled heat treatment, and strict dimensional inspection, ZHITIAN ensures every barrel section achieves tight tolerance and excellent alignment with twin screw assemblies.
This minimizes installation time, reduces mechanical deviation, and maintains consistent extrusion pressure and throughput.


3. Food-Grade Material Options (Nickel-Free)

Material Type Grade Example Key Features
Nitrided Steel 38CrMoAlA High surface hardness and fatigue strength after nitriding, suitable for food and starch extrusion
Tool Steel W6Mo5Cr4V2 Superior wear resistance for abrasive ingredients and high-load zones
Stainless Steel 316L / 440C Corrosion-resistant and hygienic, safe for food contact
Bimetallic Liner Fe-Based Alloy Extended lifetime under high filler or abrasive conditions

All materials are nickel-free and selected to meet food processing safety standards, ensuring hygienic extrusion with minimal contamination risk.


4. Key Performance Highlights

  • OEM Replacement Precision – 100% compatible with EV53 extruder configuration

  • Dimensional Accuracy – Tight machining tolerance for smooth screw operation

  • Durable Surface Treatment – Nitrided or alloy-lined for enhanced wear resistance

  • Temperature Control – Integrated cooling channels maintain stable extrusion temperature

  • Customizable Sections – Feed, venting, and discharge barrels available per customer requirement


5. Application Areas

ZHITIAN's EV53 barrel is widely used in:

  • Food extrusion systems (snacks, cereals, proteins, starch)

  • Pet food and aquatic feed extrusion

  • Powdered or viscous material processing lines

  • OEM replacement and customized extruder upgrades

It is particularly suited for high-hygiene and continuous operation environments, where consistent performance and durability are critical.
