Title: Innovations by David A Johnson

Introduction

David A Johnson is an accomplished inventor based in Metairie, LA (US). He has made significant contributions to the field of food processing technology, holding 2 patents that showcase his innovative approach to cooking and chilling food products.

Latest Patents

One of his latest patents is titled "Apparatus and method for continuous high-volume steam cooking." This invention presents an improved apparatus and method for uniformly cooking thick layers of food products in a saturated steam environment. The design features a foraminous conveyor belt that transports food into a cooking chamber, where pure saturated steam is trapped to ensure even cooking. The system utilizes a pressurized source of cooking energy that supplies steam through a network of pipes, allowing for effective penetration of steam into thick product layers. This innovation enhances cooking uniformity and prevents the formation of turbulent flow paths that could introduce unwanted air into the cooking region.

Another notable patent is the "Conveyor system for chilling food products." This invention comprises an elongated water tank and a modular movable belt conveyor unit that carries warm food products through water for chilling. The system is designed to optimize cooling efficiency by recirculating and rechilling cooling water, while controlling the temperature of the efflux water. The design includes multiple cooling stations along the conveyor belt path, which incrementally chill the product, thereby reducing the average cooling time. The apparatus is particularly effective for cooling steam-cooked food products, such as lobster and seafood.
