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.

A grilling machine is described, which comprises a base body, a plate, arranged on the base body and defining a cooking surface whereon foods to be cooked are laid, and heating means operationally associated with the plate for heating the cooking surface. There is also a circuit, associated with the plate, for treating the fumes produced during the food cooking process. The fumes treatment circuit comprises: a hood arranged above the plate, which comprises at least one suction mouth, a filtering unit fluidically connected to the hood, and at least one recirculation outlet fluidically connected downstream of the filtering unit and located near the plate. In this manner, the cooking fumes sucked in through the suction mouth of the hood are treated by the filtering unit in order to obtain a purified flow with a given percentage of humidity. The purified flow is then recirculated towards the cooking surface through the recirculation outlet in order to exert a humidifying action on the foods.

Disclosed is a hand-shook pizza oven, including: an oven body, a baking tray, a burner assembly, and a hand-shook driving structure. The oven body is provided with a cooking chamber. The baking tray is arranged in the cooking chamber along an axis extending in an up-down direction. The burner assembly includes a burning portion extendable into the cooking chamber. The hand-shook driving structure includes a rocker rotatable around an axis extending in a horizontal direction, a driving portion rotatably provided along the axis extending in the up-down direction, and a transmission structure provided between the rocker and the driving portion, at least part of the driving portion can be extendable into the cooking chamber to connect to and drive the baking tray.

Devices, systems, and methods are provided for baking a food product in a portable baking oven. The baking oven includes a main body, lower and upper stones, a heat shield suspending the upper stone above the lower stone, and a heat element emanating heat upward to a rotating flat panel having the lower stone thereon. Convection heat from the heat element moves upward from below the rotating flat panel and past a periphery of the flat panel, channeled by the heat shield to the upper stone, to move along the upper stone, and then down along the heat shield, on the opposite side. With this arrangement, the heat element heats the upper and lower stones with convection heat moving between the lower and upper stones in a side-to-side manner.

An oven comprising a housing, a cavity located within the housing, and a rotator having a first food loading section and a second food loading section is disclosed. The cavity includes a single opening for loading a food item into the cavity. If one of the first food loading section and the second food loading section is located outside of said cavity, then the other of the first food loading section and the second food loading section is located within said cavity. A first cook setting of the oven when the first food loading section is within the cavity and a second cook setting of the oven when the second food loading section is within the cavity are independently controllable. The first food loading section and the second food loading section may be separated by a divider, which prevents heat from escaping from the cavity through the opening.
