Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a cold/warm machine (cold bottle machine) that heats or cools a product liquid filled in a bottle, can, paper container, or plastic container handled in a food machine. A liquid heating or cooling method that can be used in a device that efficiently heats or cools a liquid other than food, even if the liquid to be filled into a container is a liquid other than food. It is related to the device.

(Prior art) A conventional liquid heating or cooling device sprays a heating medium or a cooling medium while conveying the liquid in a bottle, can, paper container, plastic container, etc. using a walking beam or a conveyor. This was used to heat or cool the liquid inside the container.

(Problems to be Solved by the Invention) Conventional methods for heating or cooling the liquid filled in a container are carried out in an upright position, and the heat transfer depends on natural convection within the container. There are problems such as poor heat transfer efficiency, long processing time for heating or cooling, and problems such as the inability to uniformly heat or cool the liquid filled in the container.

The present invention was proposed to solve these problems.

(Means for Solving the Problems) Therefore, the present invention involves spraying a heating medium or a cooling medium on a container filled with a liquid while it is placed horizontally, or immersing it in a heating medium or a cooling medium, and shaking the container. The liquid in the container is stirred and simultaneously heated or cooled by being conveyed while stirring, and this is a means to solve the problem.

The present invention also provides a carrier for holding a container, a conveying device for the carrier, a swinging means for swinging the carrier,
This device is equipped with a built-in device for spraying or dipping a heating medium that heats or cools the container by bringing it into contact with the container, and is configured to sequentially receive the supply of the container and discharge it after processing, which solves the problem. It is intended as a means for

(Function) By transporting a container filled with liquid in a horizontal state and shaking the container in the a' state where it is immersed in or sprinkled with a heating or cooling heat medium, the head space gas in the container is released. It flows and stirs the liquid in the container, while at the same time promoting heat transfer for heating or cooling, allowing for uniform heating or cooling in a short time.

(Example) The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of the present invention.

In the figure, reference numeral 1 denotes a container for heating or cooling, which is held in a carrier 2 by an appropriate method (not shown). 3 is a nozzle for discharging the heating medium or cooling medium, 4, 5, 6.7

2. Reference numerals 13 and 14 are trays (or tanks) for the heating medium or cooling medium that has been destroyed in the nozzle 3. 15 is a heated or cooled container, 16 is the main body of the apparatus, 17 is a section for taking out the treated container, 18 is a section for supplying the container to the apparatus, and 19 is a chain for transporting the carrier 2, etc.

In the example of Figure 1, the tanks 8.9.10 are heating zones, and the tanks 11
An example is shown in which the tanks 12, 13 and 14 are cooling zones, and the tanks 12, 13 and 14 are cooling zones, and if only heating or cooling treatment is performed, the structure will be simpler than that shown in the figure. Furthermore, although the example shown in Figure 1 has a three-dimensional structure to save space, it can also have a two-dimensional structure if necessary. It is not necessarily necessary to start the section from one side.

Figure 2 shows the movement of containers transported by carrier 2,

Transport 3. That is, the carrier 2 is connected to the guide plates 4 to 7.
Since the container in the carrier 2 swings as shown in the figure D due to the unevenness of the guide plate, the navel space gases 20a, 20b, and 20c in the container move from the upper part to the side wall of the container due to the swinging of the container. It flows with the bottom of the container, thereby stirring the liquid in the container and at the same time promoting heat transfer for heating or cooling.

Figures 3 and 4 show another embodiment in which the container is rocked. FIG. 3 shows an example in which a container 23 held on a carrier 2 is swung by a guide plate 30 while being transported horizontally by a chain. The guide plate 30 shows the details of the guide plate 4 in FIG. 1, and as shown in the figure, the carrier is conveyed and swings the containers 23 on the trapezoidal upper surface. Reference numeral 31 includes, for example, a cylinder or a link mechanism (not shown), a cam, etc., and allows the guide plate 30 to reciprocate horizontally as necessary.
This is a guide drive vJ device that allows the container 23 to swing more frequently.

In the example shown in FIG. 4, the guide plate is composed of a fixed guide plate 40 and a vertically movable guide plate 41, and the vertically movable guide plate 41 is a guide consisting of a cam 42 or a cylinder or link mechanism (not shown) The container 23 is moved up and down by a drive device, and the container 23 held on the carrier 2 is horizontally conveyed by a chain, while the container 23 is swung.

As shown in Figures 3 and 4, the magnitude and frequency of rocking can be adjusted according to the size and shape of the container to achieve the most efficient stirring and heat transfer of the liquid in the container. can. Figure 5 shows a container 23 for horizontal transportation using a chain or the like.
This is a case where the carriers are arranged in two rows so that a larger number of carriers can be processed, and even more rows can be formed depending on the structure of the carrier 2a.

(Effects of the Invention) As explained in detail above, the present invention transports the container while rocking it, thereby increasing the heat transfer for heating or cooling the liquid in the container by 1.5 to 2.0 times compared to the conventional method. It is possible to reduce the processing time by approximately half the time. Moreover, by rocking, the liquid in the container is sufficiently stirred, and the temperature and concentration become uniform.
