In what year did Clarence Birdseye file his first patent for a system using belts and brine-cooled trays?
Answer
1923
The successful engineering phase of Clarence Birdseye's quick-freezing technology culminated in the filing of his foundational patent in 1923. This patent described a specific mechanical system designed to replicate his natural observations in an industrialized setting. The system involved the use of two continuous belts that carried food items between metal trays cooled by the super-chilled brine solution. This mechanism represented the formalization and invention of modern quick-freezing technology, setting the stage for the first commercial sales the following year.
