Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an internal heating device for a boiling kettle for boiling wort, which is a raw material for beer, or a distillation kettle for evaporating wort, a raw material for whisky.

Prior Art The boiling process is an important process in which hops are mixed into the wort supplied to the boiling kettle and boiled to coagulate proteins and extract the hops, thereby determining the taste of beer.

The distillation process is a process for boiling the wort or the still supplied to a still (initial distiller, second distiller) and cooling the generated steam to obtain distilled water.

What all processes have in common is that it is necessary to vigorously boil or bring the stock solution to a boil and to achieve convection of the stock solution at a high flow rate.

For this reason, conventionally, as shown in Fig. 1a, the pot 1
A method of immersing the entire internal heating device 3 of the double circular tube 2 in the undiluted solution and heating the undiluted solution by passing steam through the passage 4, or as shown in FIG. 1b, the internal heating device of the coil 5 Methods such as passing steam through the pot 6 have been put to practical use, but since all of these methods have low boiling or boiling strength (indicated by the two-dot chain line in the figure), a steam jacket 7 is further placed at the bottom of the pot 1. I was making up for it.

That is, in the double circular tube 2 or the coil 5, the surface area in contact with the stock solution was larger than the surface area in contact with the steam, which caused the boiling or boiling strength to be weak.

In addition, in the case of the double circular tube or coil 5, when dirt such as scale is attached, the contact surface of the raw solution is uneven, making cleaning difficult, which causes a decrease in thermal efficiency.

Purpose of the Invention The present invention aims at convection of the stock solution in this type of boiling pot or distillation pot without using a steam jacket or the like, with strong boiling or boiling strength, at a high flow rate, and at the same time cleaning the solution quickly and completely. By doing so, the efficiency of boiling or boiling of the stock solution is improved.

SUMMARY OF THE INVENTION The present invention provides a device main body in which a large number of small-diameter inner tubes passing through the upper and lower plates are arranged in a hollow space between the upper plate and the lower plate surrounded by an outer cylindrical body. The present invention provides an internal heating device for a boiling pot or distilling pot, which is installed in the center and is configured to instantaneously heat the stock solution in the inner tube by the steam supplied to the hollow chamber.

Embodiment As shown in FIG. 2, the pot body 13 has a large-diameter container shape supported on a vertical support 12 erected on a work floor 11, and an exhaust duct 14 is provided at the top of the pot body 13. A boiling pot 16 is provided with a cone-shaped ceiling 15 integrally connected, and hops are introduced from a hop input pipe 18 into the wort that has been supplied from a wort introduction pipe 17 into the pot body 13 to a set level L. Then, the wort is heated and boiled by an internal heating device 20 erected in the center on the bottom surface 19 of the pot, and then the wort is taken out of the pot from a discharge port 21 on the bottom surface 19 of the pot.

As shown in FIGS. 3 and 4, the internal heating device 20 is constructed by welding and fixing a thin, large-diameter outer cylinder 24 to a disk-shaped upper plate 22 and a lower plate 23. A device main body 26 is provided which airtightly surrounds the outer peripheries of the plates 22 and 23 and has a hollow chamber 25 formed therein.

A medium-diameter steam introduction pipe 27 is inserted into the center of the hollow chamber 25 of the device main body 26 from the lower plate 23 side, and its tip is fixed to the lower surface of the upper plate 22.
7 is provided with an air vent pipe 28, and a drain discharge pipe 29 extending coaxially from the lower plate 23 surrounding the steam introduction pipe 27, so that the drain discharge pipe 29 and the steam introduction pipe 27 are connected to the pot. The device main body 26 is erected on the pot bottom surface 19 by penetrating the bottom surface 19 and fixing the drain discharge pipe 29 to the pot bottom surface 19 via a bracket 30.

The height of the device main body 26 is set so that the upper plate 22 and the set level L are separated by a predetermined distance L.

The lower part of the steam introduction pipe 27 is connected to a steam supply means, and the introduced steam is supplied into the hollow chamber 25 from the slit 31 on the upper side, while the air vent pipe 2
8, the upper part passes through the steam introduction pipe 27 and enters the hollow chamber 25.
The lower part passes through the steam introduction pipe 27 and is connected to the air venting means, and the drain discharge pipe 2
The upper part of 9 opens into the hollow chamber 25 at the lower plate 23 surface,
The lower part is connected to a drain discharge means.

On the other hand, inside the hollow chamber 25, an upper plate 22 and a lower plate 23 are provided.
A thin-walled, small-diameter inner tube 32,...
..., 32 are arranged in large numbers at predetermined small intervals P.

For example, if the inner diameter of the hollow chamber 25 is about 1600 mm, the inner tube 32 with an outer diameter of 50 mm and a spacing P of 75 mm is
330 pieces will be placed.

If the internal heating device of the boiling pot is configured as described above, the wort is supplied into the pot body 13 up to the set level L, and the steam is introduced from the steam supply means into the steam introduction pipe 27 with hops mixed therein. Slit 31
When supplied into the hollow chamber 25 from the inner tubes 32,...
..., 32 are heated from the outer peripheral side.

Air in the steam is discharged from the air vent conduit 27 to the air vent means, and condensate in the steam is discharged from the drain discharge pipe 29 to the drain discharge means.

A small amount of wort that has flowed into each of the inner tubes 32, . It comes to be ejected from the upper plate 22 side.

Therefore, the wort is spouted out from each of the inner tubes 32, .

Next, to clean the internal heating device 20, high-pressure cleaning water is injected into the inner tube 32 from the upper plate 22 side and the lower plate 23 side, and the inner surface of the inner tube 32 is quickly and completely cleaned. It becomes like this. Since the flow rate inside the inner tube 32 is fast, it is difficult for dirt such as scale to accumulate.

In addition, in the above embodiment, only an example in which the present invention is employed in a wort boiling pot is shown, but it may be adopted in a whiskey first distillation pot or a second distillation pot to evaporate the stock solution.

In this case, as shown in FIG.
It is effective to disperse and arrange about five internal heating devices 20 within the heating device 3.

Effects of the Invention The present invention is capable of instantaneously heating the stock solution using a large number of inner tubes penetrating the hollow chamber formed by the upper and lower plates and the outer cylindrical body. , can produce convection at a high flow rate,
No need for a traditional steam jacket.

Furthermore, during cleaning, scale and other dirt can be completely removed by simply jetting high-pressure cleaning water into the inner tube.
