Abstract
A method for assembling a rigid industrial food-cooking container is disclosed wherein metal sheets respective recesses and projecting elements are first assembled and then shaped to a specific predetermined geometry for receiving the industrial food and the sheets temporarily connected and assembled at right angles, and welded or brazed to cover the entire contact surface between the sheets to provide a leak proof container for the industrial cooking of the food.
Claims18
A method for assembling a rigid industrial food-cooking container including at least a first sheet (7) and a second sheet (1), comprising:
- (a) conferring the required shape on a first sheet (7) and providing a recess (9, 9′, 9″, 31) for receiving a projecting element (3) on a second sheet (1) at the required contact location between the said recesses (9, 9′, 9″, 31) in the first sheet (7) and a projecting element (3) on the said second sheet (1);
- (b) conferring the required shape on a second sheet (1) and providing a projecting element (3) whose geometry is adapted to enter the recess (9, 9′, 9″, 31) in the first sheet (7), at the required contact location between the projecting element (3) on the second sheet (1) and the recess (9, 9′, 9″, 31) in the first sheet (7);
- (c) providing a temporary connection of the first sheet (7) to the second sheet (1) by nesting the projecting element (3) on the second sheet (1) in the recess (9, 9′, 9″, 31) in the first sheet (7) characterized in that the two sheets are assembled at right angles;
- (d) providing the final connection of the first sheet (7) and of the second sheet (1) by welding or brazing in the same relative positions as those of the sheets (7,1) achieved at step (c), over the contact surface between the end (5) of the second sheets (1, 17, 21) and the first sheets (1, 15, 19) characterized in that the welding or brazing is carried out over the entire contact surface (13) between the end (15) of the second sheets (1, 17, 21) and the first sheets (1, 15, 19) for providing the industrial food-cooking container.
A method for assembling an industrial food-cooking container including at least a first sheet (7) and a second sheet (1), comprising:
- (a) conferring the required shape on a first sheet (7) and providing at least one recess (9, 9′, 9″, 31) for receiving a projecting element (3) on a second sheet (1) at the required contact location between the said recesses (9, 9′, 9″, 31) in the first sheet (7) and a projecting element (3) on the said second sheet (1);
- (b) conferring the required shape on a second sheet (1) and providing a projecting element (3) whose geometry is adapted to enter the recess (9, 9′, 9″, 31) in the first sheet (7), at the required contact location between the projecting element (3) on the second sheet (1) and the recess (9, 9′, 9″, 31) in the first sheet (7);
- (c) providing a temporary connection and pre-positioning of the first sheet (7) to the second sheet (1) by nesting the projecting element (3) on the second sheet (1) in the recess (9, 9′, 9″, 31) in the first sheet (7) to provide a contact surface;
- and
- (d) providing a final connection of the first sheet (7) and the second sheet (1) by welding or brazing in the same positions achieved in step (c) over at least a part of the contact surface between the end (5) of the second and first sheets to provide an industrial food-cooking container for cooking the industrial food in the container.
The method of claimed 1, wherein the container comprises a receptacle having a shape specific to the industrial food for cooking the industrial in the container.
