A food processing apparatus (20) such as a coffee brewer having functional elements (45) protectively contained with a housing assembly (43) composed off a wall assembly (44, 448, 44B) having wall panels (58,60,62 and 64) being formed from a single, thin-sheet, metallic work piece (50) that extend b
A food processing apparatus (20) such as a coffee brewer having functional elements (45) protectively contained with a housing assembly (43) composed off a wall assembly (44, 448, 44B) having wall panels (58,60,62 and 64) being formed from a single, thin-sheet, metallic work piece (50) that extend between corners (66,68,70 and 72) formed in the work piece by folding the work piece (50) at each of the corners with at least one fold having an angle substantially different from a right angle. After the corners are formed, opposite ends (52,54) of the work piece are aligned in abutting relationship at a location laterally spaced from all the plurality of corners and permanently welded together with a weld joint (56). As a result of bringing together the opposite ends, at least one of the panels is stressed into an arcuate shape and also forms interior corner angles at opposite sides that are substantially different from a right angle. A closure base (48) is attached to the bottom of the wall assembly (44) to close and support the open bottom of the wall assembly (44), and a closure top (46) attached to, supported by and closes the open top of the wall assembly (44).
