Apparatus and method for mass sterilization and pasteurization of food products

This system cooks or sterilizes prepackaged food by moving it through a series of sealed chambers. Food packages enter through an inlet with parallel screws, are heated by microwaves in a pressurized tunnel, and then held at temperature and cooled, often while submerged in liquid. The claims specifically describe a system for cooking prepackaged products.

Why it matters: Since 2008, industrial microwave technology has advanced in efficiency and control, making precise heating in complex, pressurized environments more feasible. Additionally, improvements in automation and sensor technology could simplify the operation of such a continuous, multi-stage system.

Status: ExpiredProtection ended and was never renewed
How hard to build: SpecializedCustom pressure vessels, industrial microwaves, screw conveyors.
