retort sterilizer main unit

Product Introduction

Retort autoclave integrates heating, pressurizing, circulating spray and cooling function. Multiple sterilization modes for different food packaging. No need complex foundation, install and put into production directly. Widely used for food factory, cannery, ready‑to‑eat food and wet pet‑food production line.

Core Advantages

Built for long‑term 24‑hour continuous food‑factory operation

Excellent Thermal Uniformity

±0.3℃ chamber temperature distribution, multi‑point PT100 sensors, ensure stable F₀ value for every batch of products.

Multi‑Redundant Safety System

Mechanical‑electronic dual‑interlock door, dual safety relief valves, pneumatic seal monitoring for pressure‑vessel protection.

Energy‑Saving Heat Recovery

Closed‑loop hot‑water recycling system, reduce steam & water consumption by up to 30% for multi‑batch production.

Intelligent PLC Control

Store over 100 sterilization recipes, auto heating‑holding‑cooling cycle, data logging for FDA audit requirement.

Working Principle

Different sterilization modes for different packaging requirements

Water‑spray / water‑immersion / steam‑air mixing retort adopt circulating hot‑medium to realize high‑temperature pressure sterilization inside chamber.

  • Adjust over‑pressure dynamically to avoid pouch / jar deformation & leakage.
  • Complete heating, F₀ holding and forced cooling full‑auto cycle.
  • Real‑time record temperature & pressure data for QA traceability.

Rotary retort drives basket rotation during sterilization, accelerate heat penetration for high‑viscosity sauce, soup products and prevent local scorching.
