    • A tunnel-type conveyor oven having two types of heat sources is provided. The oven includes a conveyor for carrying items through the oven along a conveyor path. The conveyor has first and second opposite sides. A plurality of radiant heaters are located transverse to and extend across the conveyor path. The radiant heaters are spaced apart in a direction of the conveyor path. Each radiant heater includes an inner tube having a wall with a plurality of openings defined therethrough, an open first end and a second end. A burner is directed into the open first end of the inner tube. An outer tube is located around the inner tube. The outer tube has an outer surface which is adapted to radiate heat, a first end and a second end. An exhaust outlet is located on the second end of the outer tube. The radiant heaters are arranged such that with every other heater, the burners are located on the first side of the conveyor, and with the remaining heaters, the burners are located on the second side of the conveyor for uniform radiant heat distribution across the conveyor. An exhaust manifold is connected to the exhaust outlet of at least one of the heaters. A penthouse chamber is located above the plurality of radiant heaters, and the exhaust manifold is connected to the penthouse chamber. A convection heating system is also provided which includes an upper convection heater located above and extending across the conveyor path. The upper convection heater has an upper plenum with supply areas located between each of the radiant heaters. The supply areas each have a plurality of openings directed toward the conveyor path. A lower convection heater is located below the conveyor path and includes a lower plenum having a plurality of openings directed toward the conveyor path. A convection air manifold is connected between the penthouse chamber and the upper and lower plenums to deliver the products of combustion from the radiant heaters collected in the penthouse chamber to the upper and lower plenums to provide convective heat along the conveyor path.

    • The present invention comprises a rotary drive nozzle die machine for use with at least first and second dough extruders. The machine includes at least one rotatable nozzle having at least two openings for extruding at least two strands of dough therethrough, a first compression head for directing a first flow of a first type of dough under pressure from the first extruder toward the at least one rotatable nozzle and a second compression head for directing a second flow of a second type of dough under pressure from the second extruder toward the at least one rotatable nozzle. A mixing chamber is connected to the first and second compression heads for receiving the first and second flows of dough, for mixing the second dough into the first dough and for directing the mixed dough to the at least one rotatable nozzle and a drive assembly rotates the at least one nozzle whereby the at least two strands of the mixed dough extruded through the at least two openings of the at least one nozzle are spiral wound together to form a single dough stream.
    • 本发明包括用于至少第一和第二面团挤出机的旋转驱动喷嘴模具机。 该机器包括至少一个可旋转的喷嘴,其具有至少两个开口,用于挤出至少两股面团通过其中;第一压缩头,用于将压力下的第一种面团的第一流从第一挤出机引向至少一个可旋转的 喷嘴和第二压缩头,用于在来自第二挤出机的压力下朝向至少一个可旋转喷嘴引导第二类型面团的第二流。 混合室连接到第一和第二压缩头,用于接收第一和第二面团流动,用于将第二面团混合到第一面团中并将混合面团引导到至少一个可旋转喷嘴,并且驱动组件使 至少一个喷嘴,其中通过所述至少一个喷嘴的所述至少两个开口挤出的所述混合面团的至少两股被螺旋缠绕在一起以形成单个面团流。
