A conveyor device for food includes bar members coupled with coupling members to form a conveyor belt. A guide rail supports the belt, and a sprocket meshes with tooth-shaped portions formed on the coupling members. Each coupling members includes a metallic insert member. A wear resistant resin member incorporating the metallic insert member has a bent shape with an interior space(s), both end portions coupled to a first bar member, and a pair of slotted holes in which a second bar member which is adjacent to the first bar member is loosely fitted. Wear resistant resin members form tooth-shaped portions and slide surfaces which slide on the guide rail. Meshing portion of the sprocket which meshes with the tooth-shaped portions is formed of wear resistant resin. Contact pressure and friction in a slide portion between the belt and the slide portion is prevented from increasing in low temperature environments.

Conveyor device for conveying food

To prevent the production of metal powder in a conveyor device for conveying food (), and prevent the contact pressure and wearing from increasing at the slide portion between a conveyor belt (and) and a guide rail () in a low temperature environment. A conveyor device for conveying food includes a large number of round bars () which forms the conveyor belt (and), coupling members () which are fixed to both ends of each of the round bars (), a guide rail () which slidably supports the conveyor belt (and), and a slide block () fixed to each round bar () and configured to slide on the guide rail (). The coupling members () includes rotatable rollers (), the rollers () mesh with a sprocket (), and the sprocket () conveys the conveyor belt (and) in a conveyance direction. The rollers () and the meshing portion of the sprocket () include a wear resistant resin member.

In a food transfer heat treatment apparatus using a spiral transfer belt, heat treatment gas blowing means and a heat treatment gas circulating method for enhancing the heat transfer efficiency between a heat treatment gas and food and for improving the heat treatment effect are realized to expand the degree of freedom for the layout of the apparatus and to simplify the assembly. Provided is a spiral transfer heat treatment apparatus comprising endless conveyer belts () for circulating the food (f) in a store room (), and a spiral moving unit () for causing a heat treatment gas (c) to act on the food (f) while transferring the food (f) on the conveyer belts (). The spiral transfer heat treatment apparatus further comprises a heat treatment gas generating device () arranged in the inside space of the spiral moving unit (), a distribution duct () arranged between the heat treatment gas generating device () and the spiral moving unit () for receiving the heat treatment gas (c) generated in the heat treatment gas generating device (), and a plurality of hollow nozzle units () protruding from the distribution duct () between the conveyer belts () of the spiral moving unit (), thereby to inject the heat treatment gas flow toward the food (f) on the conveyer belts () arranged below and to form their upper faces () into the supporting faces of rails () for supporting the conveyer belts () slidably.

Spiral transfer heat treatment apparatus

The present invention is featured in that a plurality of transfer pieces composing a transfer conveyer are connected to be able to be piled vertically spirally, the transfer pieces having pairs of spacer members each of which is formed to have an inside-part and an outside part continuing to the inside-part and offsetting outward in lateral direction perpendicular to the transfer direction, an engaging part having a contact face extending in the direction parallel to the transfer direction being formed at the upper and lower end part of the outside-part of the spacer member; the transfer pieces can be piled such that vertically adjacent spacer members contact to each other with the contact face of the upper and lower engaging part; an inside chain and an outside chain are provided for allowing the inner side and outer side spacer members to ride on respective chain to advance the transfer conveyer; and the inside chain and outside chain are driven by a single motor.
