发明名称 CONVECTION OVEN WITH LINEAR COUNTER-FLOW HEAT EXCHANGER
摘要 A convection oven includes a cooking chamber for cooking a food product, an air circulator that circulates process air in a first direction through the cooking chamber and along a circulation path in a circulation passage. A heat exchanger includes one or more heat transfer ducts longitudinally arranged along the circulation path. One or more heating elements heat a fluid that is circulated in a second direction through the one or more heat transfer ducts which is opposite to the first direction. The process air absorbs heat from the heated fluid as the process air travels along the circulation path back to the cooking chamber. A partition wall may separate first and second parallel portions of the one or more heat transfer ducts. A heat exchanger may preheat fluid entering the one or more heat transfer ducts using heated fluid leaving the heat transfer ducts.

主权项 1. A convection oven comprising: a cooking chamber having a process air entrance and a process air exit; a circulation passage connecting the process air entrance and the process air exit; an air circulator configured to move process air along a circulation path through the circulation passage in a first direction from the process air exit to the process air exit, and configured to circulate process air through the cooking chamber; and a heat exchanger configured move the heated fluid through the one or more heat transfer ducts in a second direction opposite to the first direction, the heat exchanger including one or more heat transfer ducts longitudinally arranged in the circulation passage along the circulation path, each of the one or more heat transfer ducts being separately sealed from the cooking chamber and the circulation passage, one or more heating elements configured to heat a fluid in the one or more heat transfer ducts.
