Abstract: An object of the present invention is to provide a circulation type conveying device easily transportable, easily assembled in installation, and useful for a user by projecting tables. The circulation type conveying device (1) comprises a base (2), a carrying unit (3) placed on the upper part of the base (2) and cyclically moving carried articles, and the tables (4a) and (4b), wherein the base (2) is opened at least on one part of its upper side, the tables (4a) and (4b) are movable between a position where the opening of the base (2) is closed and a position where they are projected outwardly from the base (2) to open the opening, the carrying unit (3) is able to be placed on the opening portion of the base (2), and the tables (4a) and (4b) and the carrying unit (3) are immovably assembled into the base (2) when the carrying unit (3) is placed on the base (2).

Abstract: A circulation conveyor for foods and drinks effectively controls internal temperature of a tunnel section covering an upper portion of a circulation-type conveyor path for foods and drinks. The conveyor has a tunnel section covering an upper portion of and in the longitudinal direction of the carrying path. A cooling and heating pipe 24 inside the tunnel section in its longitudinal direction controls internal temperature of the tunnel section. In the tunnel section, upper and lower ventilation openings 32 and 33, disposed above and below, respectively, of the cooling and heating pipe 24 are provided. The ventilation openings communicate via communication pipes 30a to 30c to circulate air, and an air blowing section 34 circulates air in the tunnel section by drawing air from one of the upper or lower ventilation openings, into the pipes, and discharges the air from the other opening.
