Patent number: 7854949Abstract: Disclosed is a waffle sheet as a long-life baked product, comprising one respective rib structure on opposite surfaces of a support layer. Said support layer has the shape of a corrugated plate (1, 10, 11, 12), e.g. with a sinusoidal or angular, trapezoidal undulation, the walls of said corrugated plate having the same thickness. Ribs (5, 5?, 6) which penetrate or bridge the wave troughs (3, 3?, 3?, 3??) extend transversal to said undulation. The wave troughs (3, 3?, 3?, 3??) of both surfaces or the top face and bottom face touch or penetrate an imaginary center line (4) of the cross-section of the waffle. The average wall thickness of the ribs (5, 5, 6) corresponds to the wall thickness of the corrugated plate (1, 10, 11, 12). The ribs (5, 5?, 6) extend at an angle from or perpendicular to the apex line of the waves. The ribs (6) in the wave troughs (3, 3?) located on the top face are offset by half a separation relative to the ribs (5, 5?) of the wave troughs (3, 3??) located on the bottom face.Type: GrantFiled: February 19, 2004Date of Patent: December 21, 2010Inventor: Franz Haas

Patent number: 6820539Abstract: A charging device for a baking oven, in which the baking molds that travel through its baking line are formed by the revolving top and bottom baking plates of the oven, whose baking surfaces, which face each other along the baking line, define the top and bottom sides of the molded bodies in the baking molds. The bottom baking plates pass through an input station situated in front of the baking line in a horizontal section of their revolution. The charging device comprises a dough piece setting device in the input station above the path of the bottom baking plates, which is temporarily movable jointly with the bottom baking plates and which sets the dough pieces down at predetermined locations on the baking surfaces of the bottom baking plates.Type: GrantFiled: June 23, 2003Date of Patent: November 23, 2004Assignee: Franz Haas Waffelmaschinen-Industrie AktiengesellschaftInventors: Franz Haas, Fritz Obermaier

Patent number: 6796301Abstract: A baking oven for producing baked molded bodies has a baking line that extends along a plane from an input station to an output station. The baking molds are each formed of a bottom baking plate and a top baking plate that is set down onto the top surface of the lower baking plate. The baking molds are transported through the baking line by a lower conveyor that carries the lower mold halves. An upper conveyor above the baking line transports the upper mold halves through their path of revolution above the plane of the baking line with the plates suspended and substantially horizontally aligned and with the baking surfaces always facing down. At the beginning of the baking line, the upper conveyor sets the top baking plates, which are substantially horizontally aligned, down onto the bottom baking plates for forming the baking molds, and at the end of the baking line, it lifts them from the bottom baking plates for opening the baking molds.Type: GrantFiled: June 23, 2003Date of Patent: September 28, 2004Assignee: Franz Haas Waffelmaschinen-Industrie AktiengesellschaftInventors: Franz Haas, Johann Haas, Fritz Obermaier

Patent number: 6575083Abstract: The baking device produces endless strips of baked goods from pourable baking dough. A cylindrical baking ring of metal is disposed to rotate about its central axis, while it is supported outside its center. The baking ring has one or more endless baking surfaces on which the strips are produced. A stationary depositing device deposits baking mass onto the rotating baking surface before the baking surface travels into a baking zone. A stationary receiving device removes the at least partially baked strips from the baking ring for further processing. A stationary electrical induction coil is disposed in the baking zone. The induction coil is arranged adjacent the baking ring so that the ring, as it moves through the magnetic field of the coil, is heated by induction for generating heat with which the strips are baked from below.Type: GrantFiled: November 2, 2001Date of Patent: June 10, 2003Assignee: Franz Haas Waffelmaschinen Industrie AktiengesellschaftInventors: Franz Haas, Johann Haas, Erich Koletnik
