Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a continuous electric heating device for a fluid which performs Joule heating while continuously moving a fluid food material or the like in a pipeline, and in particular, uniformly disperses various kinds of fluids having different electrical conductivity in a short time. The present invention relates to a continuous electric heating device for a fluid that can be heated to a predetermined temperature.
[0002]
[Prior art]
In order to cook or sterilize liquid food materials such as liquid food materials, solid-liquid mixed food materials, highly viscous fluid food materials, etc. There is known a continuous conduction heating apparatus for a fluid which heats Joule in a pipeline while continuously transferring the fluid in the pipeline by a sanitary pump or the like.
[0003]
As an example of such a continuous heating device for a fluid, there is an apparatus described in Japanese Utility Model Publication No. 7-26949. In this continuous electric heating device, a conduit is formed in a rectangular tube shape having a rectangular cross section, and a long flat electrode plate is disposed in parallel on two opposing surfaces of the rectangular tubular conduit, and heating is performed. To improve the uniformity and cleanability.
[0004]
However, in this continuous electric heating device, since the plane electrode plates arranged in parallel have a large area and the distance between the electrodes is short, a minute voltage is applied to a highly conductive fluid. However, there is a problem in that the electric current flows too much, the amount of electric heating becomes small, and the temperature rises slowly.
[0005]
In Japanese Utility Model Laid-Open Publication No. 7-39320, a pair of ring-shaped electrodes are arranged in a cylindrical conduit at intervals in the longitudinal direction so as to speed up heating of a fluid. Although the current-carrying heating device is disclosed, the ring-shaped electrode has a problem that the fluid cannot be heated uniformly because the current does not flow uniformly in the fluid and tends to be short-circuited.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned problems of the conventional continuous-flow heating device for a fluid, and has been developed to continuously heat a variety of fluids having different conductivity in a pipe in a short time. It is an object to provide a heating device.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the continuous heating device for a fluid according to the present invention performs Joule heating between power supply electrodes installed in the flow path while continuously moving a substance having fluidity in the flow path. In a continuous current heating device for a fluid, a pair of electrodes are arranged substantially in parallel at a predetermined interval, and a plurality of linear flow paths whose both ends are closed by each electrode are arranged in parallel between the electrodes, A continuous energizing flow path is formed by connecting ends of adjacent linear flow paths.
[0008]
The continuous current heating device for a fluid has a pair of electrodes arranged in a substantially parallel manner at a predetermined interval, and a plurality of linear flow passages whose both ends are closed by the respective electrodes between the electrodes. Since a continuous energizing flow path is formed by connecting the ends of the adjacent linear flow paths, by increasing the distance between the electrodes sufficiently, the energizing heating amount is increased even for a highly conductive fluid. By heating in a short time and arranging a plurality of linear flow paths between a pair of electrodes, a long current flow path can be easily formed with the structure of one electrode.
[0009]
In this case, the inflow portion and the outflow portion of the fluid can be formed so as to protrude from both ends of the current flow path.
[0010]
Thereby, the inflow part and the outflow part are formed in the same direction as the energization flow path, and the energization heating device can be made compact.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a continuous current heating device for a fluid according to the present invention will be described with reference to the drawings.

And the electric heating device is provided compactly.
[0013]
The linear flow paths 1 are formed by penetrating a plurality of long holes in an axial direction in a trunk body 6 made of an insulator of rubber or synthetic resin. It is closed by fixing the large-diameter electrode 2 to the body 6.
The linear flow path 1 is connected at its end to the adjacent linear flow path 1 in a zigzag manner through a connection hole 7 in a direction perpendicular to the axis, so that one long current-carrying flow path 3 is formed. Is formed.
At both ends of the energizing flow path 3 thus formed, an inflow portion 4 and an outflow portion 5 of a fluid to be subjected to a heat treatment are formed so as to penetrate and protrude through the electrode 2.
In addition, the length of each linear flow path 1 can be changed according to the conductivity of the fluid, and accordingly, it can correspond to various kinds of fluids.
[0014]
Further, as shown in FIG. 3, the energizing flow path 3 can be formed in the trunk body 6 as a set of a plurality of linear flow paths 1.
The energizing flow path 3 is connected to two parallel linear flow paths 1 a communicating with each other through a connection hole 7 of the inflow portion 4, and the linear flow path is connected to the downstream end of the linear flow path 1 a through the connection hole 7. It has two parallel straight flow paths 1b communicating with the path 1a and communicating again with the connection hole 7 of the outflow section 5, and flowing a fluid through these two flow paths 1a and 1b at the same time to energize. It is designed to be heated.

The fluid is sent to the linear flow path 1 by a liquid feed pump or the like, and is energized to the electrode 2 when the inside of the linear flow path 1 is completely filled.
In this case, the fluid is energized between the electrodes 2 in each linear flow path 1 and is heated by self-heating.
[0016]
Thus, the fluid continuous heating apparatus according to the present embodiment has a plurality of electrodes 2 arranged in a substantially parallel manner at a predetermined interval, and between the electrodes 2, both ends of which are closed by the respective electrodes 2. Since the continuous flow paths 3 are formed side by side and the ends of the adjacent linear flow paths 1 are communicated with each other, the distance between the electrodes 2 is sufficiently long. Accordingly, even a fluid having high conductivity can be heated in a short time by increasing the amount of energized heating, and a plurality of linear flow paths 1 can be arranged between a pair of electrodes 2 to form one electrode. Thus, the long energizing flow path 3 can be easily formed.
