Abstract
The present invention relates to an oven comprising: —a first chamber and a second chambers, which are separated by separation means—conveyor means for guiding products from the inlet through these chambers to the outlet, —temperature control means for controlling the temperature and/or humidity in each chamber individually using a fluid, respectively, and—a passage in the separation means through which the conveyor means are directed from the first chamber to the second chamber.
Claims21
A method for operating an oven comprising a first chamber and a second chamber, the method comprising:
- cooking a product in the first chamber and in the second chamber with a heated fluid,
- transporting the product with a conveyor means in a transporting direction, from an inlet of the oven, through the first chamber and the second chamber, to an outlet of the oven, the conveyor means are at least partially arranged in a helical path,
- wherein the oven comprises a separation means to separate the first chamber and the second chamber, the conveyor means pass through the separation means,
- wherein the method comprises establishing a pressure difference or establishing and reducing the pressure difference between the heated fluid in the first chamber and the heated fluid in the second chamber in a region of the separation means,
- wherein the method comprises adjusting a dewpoint of the heated fluid in the first chamber and in the second chamber by adjusting a recirculation rate of the heated fluid in the first chamber and in the second chamber,
- wherein the dewpoint of the heated fluid is lower in the first chamber than in the second chamber, and the first chamber has a higher recirculation rate than the second chamber, and
- wherein the first chamber is located further downstream than the second chamber, relative to the transporting direction of the product through the oven.
A method for controlling an oven comprising a first chamber and a second chamber, the method comprising:
- cooking a product in the first chamber and in the second chamber with a heated fluid,
- transporting the product with a conveyor means in a transporting direction, from an inlet of the oven, through the first chamber and the second chamber, to an outlet of the oven, the conveyor means are at least partially arranged in a helical path,
- wherein the oven comprises a separation means to separate the first chamber and the second chamber, the conveyor means pass through the separation means,
- wherein a pressure difference between the heated fluid in the first chamber and the heated fluid in the second chamber in a vicinity of the separation means is controlled,
- wherein the method comprises adjusting a dewpoint of the heated fluid in the first chamber and in the second chamber by adjusting a recirculation rate of the heated fluid in the first chamber and in the second chamber, and
- wherein the first chamber has a higher recirculation rate than the second chamber and is located further downstream than the second chamber, relative to the transporting direction of the product through the oven.
