  An object of the present invention is to provide a low-temperature distillation separation apparatus which can be separated into a plurality of different distillates and concentrates and a separation method thereof, which are excellent in flavor and aroma by distillation at a low temperature.

A low-temperature distillation separation apparatus according to the present invention includes a reduced-pressure low-temperature heating tank, a swirl separation tank that swirls and separates primary distilled steam generated from the reduced-pressure low-temperature heating tank, and a secondary distillation distilled from the upper part of the swirl separation tank. A cooling condenser for cooling and condensing steam and a distillate tank for storing a distillate condensed in the cooling condenser are provided.
Here, the swirl separation tank preferably has a storage tank in the lower part and can be switched so that the concentrated liquid flowing down along the side wall can be returned to the reduced-pressure low-temperature heating tank.
In the present invention, the reduced-pressure low-temperature heating tank refers to one that can be depressurized so that the treatment liquid boils at 60 ° C. or less, and can be adjusted to a vacuum degree of 0.5 × 10 ^{−6 to} 0.95 × 10 ⁻⁶ Pa, The thing which can be temperature-controlled to the temperature of 30 to 60 degreeC is good.
Preferably, it can be adjusted to ^{0.8 × 10 -6 ~0.95 × 10 -6} Pa degree of vacuum, it is intended to be controlled at a temperature of 40 ° C. to 50 ° C..
In addition, the swirl separation tank is a swirling flow created by jetting steam from the tangential lateral direction into a tank having a circular cross section, and a relatively light steam is taken out from the upper part. It moves to the tank wall and flows down.

The low-temperature distillation separation method according to the present invention includes a step of charging a stock solution into a reduced-pressure low-temperature heating tank and performing low-temperature heating at 60 ° C. or less under reduced pressure, and a primary distilling steam generated from the reduced-pressure low-temperature heating tank to the swirl separation tank. A distillate obtained by cooling and condensing light secondary distilled steam collected from the upper part of the swirl separation tank with a cooling condenser. The conc liquid flows down to the lower part of the swirl separation tank, and the concentrate is separated and recovered into the concentrate remaining at the bottom of the reduced-pressure low-temperature heating tank.

In the present invention, the stock solution to be separated is put into a reduced-pressure low-temperature heating tank, depressurized to a predetermined vacuum, and distilled at a low temperature of 30 ° C. to 60 ° C., for example, fragrance components and vitamins Components that decompose at high temperatures can be separated as they are as distillate or concentrate, so that they can be separated by distillation even for liquids containing thermally decomposable components.
In addition, since it has a swirl separation tank that swirls and separates the primary distilled steam generated from the low-pressure low-temperature heating tank, it is included in the distillate collected from the upper part of this swirl separation tank and the distillate collected from the lower part thereof. The components can be separated into distillates having different flavors and the like.
When the separation apparatus and the separation method according to the present invention are applied to the production of distilled liquor, it is possible to obtain distilled liquors having different flavors, etc., from the upper part of the swirl separation tank and from the lower part. .
It is also possible to distill and separate as it is after making a rice cake and fermented using sake rice and koji, without adjusting the pressure using this reduced-pressure low-temperature heating tank, and only adjusting the heating temperature.
In addition, when applied to various extracts such as fruit juice, the distillate condensed and recovered from the upper part of the swirl separation tank can be used for lotion etc. near pure water, and the distillate condensed and recovered from the lower part can be used in a low-pressure low-temperature heating tank. When returning and concentrating repeatedly, the concentrate concentrated at the bottom of the reduced-pressure low-temperature heating tank becomes a water tank-like shape, and when recovered and cooled and solidified, a drop-like health food can be obtained.

It is the schematic diagram which showed the flow of the low temperature distillation separation apparatus which concerns on this invention. (A) shows the planar structure of a swirl separation tank, (b) shows the planar structure of a cooling condenser.

As shown in FIG. 1, the low-temperature distillation separation apparatus according to the present invention has a concentration tank 1 for introducing a stock solution to be separated by distillation. The concentration tank 1 includes a heater 6 and a thermometer 7 and is 30 ° C. The heating temperature is adjusted to -60 ° C, preferably 40 ° C to 50 ° C.
The upper part of the concentration tank 1 is connected to the upper part of the swirl separation tank 2 by a pipe 1a.
Moreover, the bottom part of the concentration tank 1 has the concentrate outlet 11 which takes out a concentrate by switching valve | bulb 11a.
As shown in FIG. 2A, the swirl separation tank 2 has a cylindrical shape with a circular cross section, and the spout 1b of the pipe 1a connected to the concentrating tank 1 is generally directed in the tangential direction. .
Thereby, a swirl flow is generated in the primary distilled steam from the concentration tank 1, relatively light steam collects in the upper part, and relatively heavy steam collects on the inner wall side of the swirl separation tank 2 and flows down.
The upper part of the swirl separation tank 2 is connected to a serpentine tube 3a provided in the next cooling condenser 3 by piping 2a.
In addition, the partition member 2b for vapor | steam separation surrounding the piping 2a connection port periphery of the ceiling part of the rotation separation tank 2 is provided.
On the other hand, the lower part of the swirl separation tank 2 is a reservoir 2c for the concentrated liquid C1 that has liquefied and flowed down along the peripheral wall.
The concentrated liquid C1 stored in the storage section 2c can be recovered from the concentrated liquid outlet 12 or returned to the concentrated tank 1 through the pipe 12b by switching the valves 12a and 12c.
The cooling condenser 3 has a serpentine tube 3a disposed therein, and the periphery of the serpentine tube is hollow, and the cooling water is circulated through the pipes 6a and 6b.
The snake tube 3 a passes through the inside of the cooling condenser 3 and is connected to the distillate tank 4 by piping.
The distillate tank 4 has a role as a tank for storing the condensed distillate C2 distilled and separated from the upper part of the swirl separation tank 2, and a role of depressurizing the entire system to a predetermined degree of vacuum.
Therefore, the distillate tank 4 is connected to the vacuum pump 5 and the air supply port 17 by the pipes 14 a and 15 a by switching the valves 14 and 15.
Specifically, when the valves 13a, 15, 12a, 12c, and 11a are closed and the valve 14 is opened, the inside of the distillation liquid tank 4 communicates with the inside of the snake tube 3a, the swirl separation tank 2 and the concentration tank 1, and the distillation liquid tank By operating the vacuum pump 5 and depressurizing the inside of the system 4, the entire system can be depressurized, and there is an effect of inducing distilled steam.
When the operation of the vacuum pump 5 is stopped and the valve 15 is opened, the atmosphere flows into the interior and returns from the reduced pressure state to the atmospheric pressure.
The distillate tank 4 has a distillate outlet 13 for collecting the distillate by switching the valve 13a, and a pressure gauge 8 is attached.
Reference numeral 9 is an operation panel for automatically controlling the entire apparatus.
