As in the case of spraying hot water on the conveyor, the conveyor does not get in the way when the injection nozzle is installed, and the installation is simple.

According to the invention described in claim 3 , the same effect as that of the invention described in claim 1 or 2 is obtained, and by blowing air from above the container, water droplets on the surface of the container are blown off and gravity is reduced. Water drops can be dropped using it.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 is a cross-sectional view taken along line AA of the container heat treatment apparatus shown in FIG. 3, FIG. 2 is a cross-sectional view taken along line BB of the container heat treatment apparatus shown in FIG. 3, and FIG. FIG.

  The container heat treatment apparatus 1 according to the present embodiment warms a barrel container (container) S filled with beer and raises the beverage temperature to prevent condensation on the surface of the barrel container.

As shown in FIG. 3, the container heat treatment apparatus 1 includes a conveyor 3 that conveys the barrel container S and a guide unit 5 that guides the movement of the barrel container S conveyed by the conveyor 3. The guide unit 5 forms a transport path T for the barrel container S between the two left and right guide members 7 and 7 and receives the barrel container S to guide the movement along the guide surface 5a. The guide member 7 is provided with meandering to the conveying direction, a barrel with a liquid S is in sliding contact with the forward direction to one of the guide member 7a positioned on the conveying direction lower stream side (in one direction, in the drawing C sliding contact with the reverse rotation direction (the other direction to the other guide member 7b which will be located on the downstream side in the carrying direction while being conveyed while rotating shown), as is conveyed while rotating shown in figure D) It has become.

  The guide member 7 is provided with a plurality of injection nozzles 9 for spraying hot water toward the barrel container S moving in the conveyance passage T along the conveyance direction, and the injection nozzle 9 is heated toward the barrel side surface 10 of the barrel container S. It comes to spray. Moreover, the injection nozzle 9 is arrange | positioned at the both sides of the barrel container S, and the injection nozzle 9 on either side is arrange | positioned so that it may become alternate along a conveyance direction, respectively. The injection nozzle 9 includes an upper nozzle 9a that blows hot water on the upper side of the body side surface 10 of the container, and a lower nozzle 9b that blows hot water on the lower side of the body side surface 10 of the barrel container S. The injection nozzle 9 is connected to a branch pipe 11 provided in a direction orthogonal to the transport direction, and the branch pipe 11 is further connected to a water distribution pipe 13 disposed along the transport direction. And the warm water is supplied to the injection nozzle 9 through the branch pipe 11.
