Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alcohol concentration detection device for a potable alcohol distillation device.

Conventionally, in equipment for distilling drinking alcohol such as malt whiskey, the alcohol concentration was detected using a Baume meter, and distillation was stopped when the alcohol concentration fell below a predetermined value.However, measuring alcohol concentration using a Baume meter requires manual labor. Therefore, it was difficult to automate the control of the distillation equipment.

Alcohol concentration is generally detected by measuring its density.

Density measuring instruments for this purpose have a wide variety of structures, measurement principles, etc., and the measuring instruments used are selected according to usage conditions such as required accuracy and temperature.

It has been proposed to configure an alcohol concentration measuring device by combining a density meter, that is, a density meter and a flow meter, but the difficulty in measuring the concentration of distilled alcohol with this type of measuring device is that Alcohol contains a large amount of air bubbles and impurities (esters, patina, etc.), so a linear relationship cannot be established between density and alcohol concentration.

Air bubbles must be removed when measuring density, and impurities not only cause errors in density measurement results, but also
Adhesive impurities need to be removed because they clog the detection element of the density meter, piping, and flowmeter.

Due to the above-mentioned special properties of drinking alcohol, it has been difficult to continuously and automatically measure the concentration of distilled alcohol.

After examining various density meters to continuously measure the concentration of distilled alcohol, the inventor discovered that a vibrating density meter was suitable. An attempt was made to construct an alcohol concentration measuring device.

The present invention provides a drinking alcohol concentration detection device that fully utilizes the performance of the alcohol concentration measuring device having the above-mentioned vibrating density meter, and makes it possible to automatically and continuously measure alcohol concentration, which has been considered difficult in the past. It is.

According to the present invention, a potable alcohol distillation device receiver includes a sampling device for sampling clean alcohol flowing into a tank, an alcohol concentration measuring device provided on the downstream side of the sampling device, and a sampling device for sampling clean alcohol flowing into a tank after stopping distillation of the distillation device. a discharging device for discharging a sample of clean alcohol that has flowed into the device and the alcohol concentration measuring device; a purifying device for cleaning and air purging the alcohol concentration measuring device; and a purifying device for cleaning and air purging the alcohol concentration measuring device; There is provided an alcohol concentration detection device for a drinking alcohol distillation device, comprising a control device that stops the distillation device, operates the discharge device, and then operates the purification device when the alcohol concentration falls below a certain value.

The above sampling device is equipped with a defoaming tank that removes air bubbles from clean alcohol and a filter that removes impurities, minimizing the measurement error of the alcohol concentration measuring device. All the sample alcohol remaining in the device and the alcohol concentration measuring device is discharged, and the purifying device includes a device for flowing a cleaning liquid for cleaning the alcohol concentration measuring device and an air purge device.

As described above, in the alcohol concentration measuring device of the present invention, all the sample alcohol is discharged after the distillation device is stopped, and the sample alcohol is not trapped in the device for a long time, which is sanitary.

Furthermore, since the measuring device is purified by the purifying device, viscous impurities will not stick and accumulate and cause clogging.

Furthermore, according to the embodiment of the present invention, the sampled alcohol (i.e., sample alcohol) is returned to the tank after receiving clean alcohol from the distillation device after measurement, so that the downstream side of the measuring device is not operated during operation of the distillation device. The receiver communicates with the tank, and a switching valve is provided which is switched by the control device so that the downstream side of the measuring device is communicated with the drain after the distillation device is stopped.

Therefore, the sample alcohol is used as a product without being discarded after measurement, which is economical.

However, it is provided to switch the pipe line 31 to communicate with the pipe line 10.

The purification device includes a cleaning water supply device for supplying cleaning water and an air supply device for air purging.

The cleaning water supply device includes the main components of a water supply source 26, a needle valve 28, a shutoff valve 30, and a pipe line 27 connecting these components.
, 29.

As a result, cleaning water flows into the pipe line 31 via the shutoff valve 30.

The air supply device has an air supply source 32, a needle valve 34, an air filter 36, a pressure control valve 38, and a cutoff valve 40 as main components, and pipes 33, 35, 37, 39 are connected therebetween.
It communicates with

This allows compressed air to flow into the pipe line 31 from the shutoff valve 40.

A directional control valve 1 is installed downstream of the vibrating density meter 13 of the measuring device.
5 is provided.

This switching valve 15 forms a part of the discharge device described below, and when the distillation device 1 is in operation, the sample liquid after measurement is allowed to flow through the pipe line 18 to the receiving tank 16, and after the distillation device 1 is stopped, The flow direction is changed so that the water flows into the drain tank 20a through the channel 19.

The discharge device discharges the sample liquid from the defoaming chamber A of the liquid tank 6, which is composed of a pipe line 21 branched from the sample liquid supply pipe line 5, a shutoff valve 22, and a pipe line 23, and a pipe line 24. , a shutoff valve 25, and a pipe line 20 for discharging the sample liquid from the filtration chamber B.

The control device 52 operates upon receiving the output signal from the concentration meter 51.

That is, when the alcohol concentration falls below a predetermined value, the control device switches the cutoff valves 22 and 25 and the directional control valve 15 to discharge the sample liquid in the sampling device and the measuring device to the drain 20a, and then drains the sample liquid in the sampling device and the measuring device into the drain 20a. After cleaning, the cleaning water is flowed into the measuring device by switching the directional control valve 9, and then the shutoff valve 40
Sequence control is performed to flow compressed air to the measuring device and purge the measuring device.

The operation of this embodiment will be explained below.

When the distillation apparatus 1 is in operation, clean alcohol flows through the pipe 2 into the tank 16, where it is stored.

Sampled by pipe line 3 branching from pipe line 2,
A sample liquid for measurement is taken out.

The amount of sampling can be changed by adjusting the needle valve 4.

The sample liquid flows into the defoaming chamber A from the lower part of the liquid tank 6.

At this point, air bubbles mixed into the sample liquid are removed, and the sample liquid enters the filtration chamber B by crossing the partition plate 6a.

The sample liquid from which impurities and sticky substances have been removed by the filter 7 sequentially flows through the pipe line 8, the directional control valve 9, the pipe line 11, the flow meter 12, and the vibration density meter 13.

Alcohol concentration is detected by the concentration meter 51 based on the relationship between the flow meter 11 and the density meter 13.

The alcohol concentration detected by the concentration meter 51 is converted into an electrical signal and sent to the control device 52.

At the same time, the control device 52 opens the shutoff valves 22 and 25 to drain the sample liquid in the degassing chamber A and the filtration chamber B of the liquid tank 6, and switches the directional switching valve 15 to drain the sample liquid in the measuring device.

After the sample liquid is drained, the control device 52 switches the directional control valve 9 to the side where the purifying device and the measuring device communicate with each other, and opens the cutoff valve 30.

This causes cleaning water to flow into the measuring device and flushing the measuring device.

After flushing the predetermined time measurement device, the control device 52
The shutoff valve 30 is closed, the shutoff valve 40 is opened, and compressed air is sent to the measuring device for air purging.

As a result of the above, sticky substances, etc. pass through the filter 7 to the flow meter 11.
Even if it gets into the vibration density meter 13 and adheres to it, it is cleaned and air purged every time the distillation device 1 stops operating, so the measuring device is always kept clean and does not interfere with its function.

Furthermore, all of the sample liquid is discharged from the concentration detection device,
It is hygienic because it is not trapped while the operation is stopped.

Although the present invention has been described above in the form of embodiments, the present invention is not limited to the above embodiments, and can be modified in various ways within the scope defined by the claims.
