Multiple pass linear oven

Abstract

A multiple pass linear oven for heating food products. The linear oven has multiple passes that run through the oven vertically in order to shorten the length of the linear oven, while still maintaining the amount of time the food product is spent inside the oven. The use of multiple levels of conveyor in one linear oven saves space and money. A second multiple pass linear oven has different stations performing different functions. Each station is set up along one conveyor. This allows the food product to remain on one conveyor while being treated three different ways.

1 . A multiple pass linear oven for heating food products having:
 multiple passes carrying the food product through the oven vertically;   an entry conveyor that allows the linear oven to switch from multiple to single pass; and,   multiple stations for providing different functions to the food product as it passes through each station.
