[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the solid-liquid mixture tube transfer apparatus and method in the food brewing industry of the present invention will be described in more detail.
[0012]
FIG. 1 is a schematic view of a solid-liquid mixture tube transfer apparatus of the present invention. As a specific example, for example, in a shochu manufacturing facility, raw wheat is stored as a solid in the solid tank 1, and the liquid tank 2 is a water tank. These are generally mixed in the mixer 3 with wheat 1: water 1.2. This mixture is sent to the preparation tank 6 by a transfer pump 4 and a main pipe 5 as main transfer means. The length of the main pipe 5 varies depending on the arrangement of each device in the factory, but may be close to 100 m.
[0013]
In the solid-liquid mixture pipe transfer device according to the present invention, the sensor unit detects that some abnormality has occurred in the main transfer means, generates a signal, and is provided with detection / control means 7 for eliminating the abnormality by the signal. . The detection / control means 7 detects a stop of the transfer pump 4 or an abnormality in the transfer state. A thermal relay, a motor relay, an ammeter, a tachometer, a photoelectric sensor, a proximity sensor, etc. are used to detect the stop of the pump. Yes, pressure sensors, vibrometers, flow meters, ammeters, etc. are effective for detecting abnormalities in the pump or transfer state.
[0014]
More specifically, an example of the sensor unit that detects the stop of the transfer pump will be described. The thermal relay is incorporated in the drive motor circuit of the transfer pump 4 and detects the relay signal. The ammeter detects that the current value of the drive motor of the transfer pump has become zero, and the tachometer detects that the shaft rotation of the pump has become zero. The photoelectric sensor detects the stop signal when the light that is interrupted intermittently during the rotation of the pump is continuously blocked or passed by the protrusions attached to the pump shaft for detection. It is a thing.
[0015]
As an example of a sensor for detecting various phenomena due to abnormalities in the transfer pump or the transfer state, the pressure sensor notifies that the pressure of the pressure gauge attached to the pipe on the secondary side of the pump has exceeded a predetermined value. . The vibration meter detects that the vibration value of the vibration meter attached to the pump exceeds a predetermined value, and the flow meter detects that the value of the flow meter attached to the main pipe is outside the predetermined range. Further, the ammeter detects that the current value of the drive motor of the transfer pump 4 has exceeded a predetermined value, and in order to operate the auxiliary transfer means 8 of the present invention described below, the ammeter is connected to the main pipe 5. Open / close control of each connected valve. The opening / closing drive source of the valves is a mechanical type using compressed air, a battery, or a spring.
[0016]
As described above, the auxiliary transfer means 8 detects an abnormality of the transfer pump 4 as the main transfer means, and eliminates clogging of the transferred material in the main pipe 5, as shown in FIG. In addition, an air supply path 11 communicating with the main pipe 5 via the high-pressure air tank 9 and the air valve 10, and a liquid supply path 15 comprising an air inlet valve 13 branched from this to the auxiliary liquid tank 12 and an outlet liquid outlet valve 14. Is provided.
[0017]
If another specific example of the auxiliary transfer means 8 of the present invention is shown, an elastic body supply path for forcibly pushing out the solid-liquid mixture clogged in the main pipe 5 using the air supply path 11 or the liquid supply path 15. 16 can be mentioned. The elastic body supply path 16 includes a spherical elastic body 17, an extrusion device 18 thereof, and a pinch valve 19 through which the elastic body 17 passes. Also, instead of a pinch valve, a pin is inserted at right angles to the path through which the elastic body passes, so that the elastic body does not move to the main pipe during normal operation, and when the auxiliary transfer means is activated, the pin can be pulled out by an air cylinder etc. and moved to the main pipe It may be a thing. As the extrusion device 18, for example, an air cylinder or an air gun is used.
[0018]
The control method of the detection is demonstrated below, further demonstrating more specifically the solid-liquid mixture pipe | tube transfer apparatus in the food brewing industry of this invention. For example, in a shochu facility, the solid raw material wheat (steamed barley) and water as a solid-liquid mixture are mixed at a ratio of approximately 1: 1.2, and the tank (3B x approx. There is a main transfer line to send to. When an emergency such as an abnormality or a power failure occurs in the pump, a method for automatically avoiding an emergency such as blockage of a pipeline due to swelling of wheat by providing auxiliary transfer means 8 has been implemented.
[0019]
Here, the auxiliary transfer means is operated as follows. First, at the time of a power failure, the auxiliary transfer is performed immediately after the sequencer operating by the emergency battery charged during energization detects the power failure electrically because the relay signal of the transfer pump is closed. In order to ensure the power required to operate the means, the generator is activated. The air valve 10 of the high-pressure air tank 9 containing compressed air connected to the main pipe 5 through the air valve 10 is opened and air is blown into the main pipe 5 through the air supply path, and the water / wheat mixture is urgently transferred in the pipe by the pressure. .
[0020]
When it is determined that the solid in the main pipe cannot be sufficiently transferred by air blowing alone, the liquid discharge valve is connected to the auxiliary liquid tank 12 via the air inlet valve 13 so that water can be pushed out with compressed air. 14 is opened, water is pushed out from the liquid supply path 15 into the main pipe 5, and the water / wheat mixture clogged in the main pipe is urgently transferred. If water alone is insufficient, air is simultaneously blown into the main pipe 5 from the air supply path 11.
[0021]
If the transfer is still inadequate, in addition to these air and water, an elastic body 17 that can be substantially slidably contacted with the inner surface of the main pipe 5 is moved from the pinch valve 19 into the main pipe 5 through the elastic body supply path 16 by the extrusion device 18. Extruding and moving the elastic body 17 in the pipe with the pressure of the air from the air supply path 11 and / or the water from the liquid supply path 15 and moving the water / wheat mixture in the pipe Emergency transfer at. By properly using air, water, and elastic bodies from the three paths of these auxiliary transfer means 8, most troubles of tube clogging can be solved. This means can also be used for simple cleaning of the main pipe 5. In addition to the above-mentioned means, the auxiliary transfer means can be controlled by a two-port single-coil solenoid valve by using a two-port single-coil solenoid valve that opens with a spring and flows compressed air at the same time as the power failure.
[0022]
The above is a case where the transfer pump 4 is stopped due to a power failure, but an abnormality is detected even if the transfer pump 4 is not stopped. For example, when the pressure gauge provided on the secondary side of the transfer pump 4 exceeds a predetermined pressure, the transfer pump 4 is turned off. This can be solved by urgently transferring the water / wheat mixture in the pipe by operating the auxiliary transfer means while moving it and increasing the water ratio in the water / wheat mixture ratio. When the clogging of the main pipe is slight, it can be dealt with only by lowering the solid ratio of the mixed transfer by the detection / control means 7 without using these auxiliary transfer means.
[0023]
As a specific example of the other solid-liquid mixture of the apparatus and method of the present invention, the soy sauce production facility is mixed with straw and salt water at a ratio of 1: 1.4 and transferred to the tank through the transfer pump 4 (Mono pump). There is a means to make it. In addition, there is a means for mixing rice and water in the sake production facility and transferring the inside of the pipe to the dipping facility by the transfer pump 4. Furthermore, there is a means for mixing soybeans and water in the miso manufacturing facility and transferring the inside of the pipe to the dipping facility by the transfer pump 4. In any case, troubles such as clogging of the main pipe can be solved by the same operation as the above-mentioned water transportation of wheat.
[0024]
【Effect of the invention】
As is apparent from the above description, according to the present invention, in the liquid transfer device containing solid matter, appropriate measures in an emergency are automatically performed, and troubles at the start-up of the production line after the cancellation in the emergency are avoided. This makes it possible to prevent product deterioration in the next process in advance. As a result, in the tube transfer process of the solid-liquid mixture in the food brewing industry, it guarantees a safe and stable operation and greatly contributes to the maintenance of product safety and quality.
