JPS60196177A - Temperature control of canned liquid beverage - Google Patents

Abstract

PURPOSE:Cans in which beverage is included are allowed to stand upright, transferred and stopped, these operations are repeated to cause forced convection in the beverage liquid and cold or warm water is sprayed to effect cooling or cold sterilization in a short time without damage on can surfaces. CONSTITUTION:Continuous conveying guide 1 is made zigzag by frame 2 and 3 conveyors 3a-3c are set in parallel under the guide. Can A in which beverage such as coffee or juice is included are fed in the upright state and the conveyors 3a-3c are intermittently driven in the arrow directions to repeat the movement and stopping cans A to cause forced convection in the beverage liquid. At the same time, cold water lower than room temperature or hot water over 85 deg.C are sprayed to effect cooling or cold sterilization, then the cans A are conveyed out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid temperature regulating method for cooling or maintaining a liquid beverage such as coffee or juice sealed in a can at a constant temperature.

In general, coffee immediately after being sealed in a can has a high temperature and needs to be cooled down, and juices are sterilized by keeping them warm for a certain period of time at a temperature around gs@c to prevent spoilage. Pasteurization is performed.

In order to efficiently cool or keep warm, conventionally the can was placed on its side and transported while being rolled to create forced convection of the liquid beverage inside the can. This method achieves its purpose in a short time by promoting dispersion, and for pasteurization, the liquid beverage inside the can is appropriately stirred to keep the liquid temperature uniform throughout the can, thereby increasing the sure sterilization effect. It had been.

However, according to the above conventional method, when one can rolls, it violently collides with other cans, which tends to damage the surface of the can.
In severe cases, this has the drawback of deforming the can and significantly reducing its commercial value.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and the can filled with the liquid beverage is stood upright on the conveying surface of a continuous conveying device such as a conveyor, and the continuous conveying device is intermittently driven. By repeatedly moving and stopping the cans, the liquid beverage inside the can is forced to circulate, and the cans being transported are sprayed with cold or hot water. By uniformizing the temperature of the liquid throughout the can in a short period of time, sterilization can be ensured.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a continuous conveyance device in which endless conveyors 3a, 3b, and 3c are arranged in parallel at the bottom of a meandering track frame 2. Conveyor conveyors 3a, 3b of the conveyance device l,
3c are respectively driven in the directions indicated by arrows in the drawing. The cans A conveyed from other processes are spread out in multiple rows at the entrance 4, are conveyed on the conveyor 3a in the direction of the arrow, and reach the end of the conveyor 3&, where they reach the bent portion 2& of the track frame 2. The paper is transported onto the transport conveyor 3b while being guided by the transport conveyor 3B, and then transported in the same manner to the exit section 5 connected to the terminal end of the transport conveyor 3C.

Therefore, the present invention provides the transport conveyors 3a, 3 of the transport device 1.
b and 3o are driven intermittently, whereby the can is conveyed while repeatedly moving and stopping, and the change in speed is used to generate forced convection in the liquid beverage. In this state, if the canister is cooled by a sprayer (not shown), it can be cooled in a much shorter time than by spraying cold water at room temperature or below and conveyed at a constant speed, and in the case of pasteurization. By spraying hot water of about rs''c, the metal body inside the can can be kept at a uniform temperature in a short time, and the sterilization effect can be significantly enhanced, especially when it contains fruit pulp such as mandarin oranges.

As described above, according to the present invention, the cans are repeatedly moved and stopped while standing upright, thereby causing forced convection to be generated in the liquid beverage inside the can and spraying cold or hot water onto the liquid beverage, thereby causing the cans to violently collide with each other. Therefore, cooling or pasteurization can be performed without damaging the surface.
In addition, since the purpose is achieved in a short time, it is useful because the equipment can be made smaller.
