Control the compressor (60), the control valve (72), the opening / closing valve (52) for the air supply unit, and the like to automatically filter and discharge the concentrated liquid supplied from the water bath.

That is, the microcomputer 86, when the automatic mode is selected by the automatic mode selection unit 86, the air pressure setting process for setting the air pressure inside the body 10 in advance, if the concentrated liquid is supplied, the filtration for filtering the concentrated liquid Process, the discharge process for discharging the filtered concentrate, when the discharge of the concentrate is completed, the washing process for washing the filtration member 30 with the washing water is automatically executed sequentially, the manual mode by the manual mode selection unit 88 If is selected, the air pressure setting process, the filtration process, the discharge process, and the washing process will be respectively controlled to be executed manually.

Referring to the operation of this embodiment configured as described above are as follows. Referring to the drawings based on FIGS. 1 to 2 as follows.

First, the user selects what kind of concentrate is to be filtered and sets the type and air pressure of the filter paper 32 according to the viscosity. The air pressure is set on the control panel of the control unit 80. Further, the manual mode selection unit 88 and the automatic mode selection unit 86 select whether to perform the filtration process manually or automatically. In the following description, the automatic mode is selected.

When the concentrate is supplied into the filtration member 30 through the concentrate supply pipe 40 in the state in which the automatic mode is selected, the first concentrate sensor 42 detects the concentrate supplied and generates a detection signal. The microcomputer 86 receiving the detection signal operates the compressor 60 to generate compressed air, and operates the heating element 66 to heat the air supplied by the compressor 60. At this time, the air temperature detection oath 67 detects the temperature of the air passing through the heating element 66 and transmits it to the microcomputer 86. Therefore, the microcomputer 86 controls the power applied to the heating element 66 based on the temperature sensed by the air temperature sensor 67 to control the temperature of the air to a set value.

Therefore, the air compressed while passing through the air filter 62 is warmed while passing through the heating element 66 and is supplied into the filtration member 30. At this time, the control valve 72 is controlled by the microcomputer 86 of the control unit 80 so as to pass only by the set amount, the air pressure inside the body 10 is maintained in the set state.

In this process, the compressed air supplied into the filtration member 30 through the door 20 pressurizes the surface of the concentrated liquid with a uniform pressure, and thus the concentrated liquid is filtered while forcibly passing through the filter paper 32. do.

The filtered concentrate is discharged to the concentrate packing machine through the discharge opening and closing valve 52 opened by the control unit 80 through the concentrate discharge pipe 50.

In this case, the control unit 80 may operate the discharge pump 56 so that the filtered concentrate is quickly discharged, and the concentrate passing through the concentrate discharge pipe 50 is discharged by the second concentrate detecting sensor 54. Whether it is detected. Therefore, when it is detected by the second concentrate sensor 54 that the discharge of the concentrate is completed, the microcomputer 86 stops the operation of the compressor 60 and the heating element 66.

Thus, the concentrated liquid supplied from the water bath to the filtering member 30 can be filtered while being forced through the filter paper 32 by the forced filtration means, and then can be quickly discharged by the discharge pump 56. Operation is automatic, and since the compressed air supplied to the filtration member 30 is warmed by the heating element 66, the concentrate is not subjected to a sudden temperature change by the temperature of the compressed air. In addition, since the compressed air is heated while passing through the heating element 66, various bacteria can be eradicated, so that the effect of sterilization can be obtained.

In this case, the filtered concentrate may be discharged by the pressure of the compressed air supplied, but the discharge pump 56 may be used for faster discharge.

In this state, if the second concentrate detecting sensor 54 does not detect the concentrate, that is, when the discharge of the concentrate is completed, the microcomputer 86 stops the operation of the discharge pump 56, and the The operation is stopped and the operation of the heating element 66 is stopped. At this time, it is a matter of course that the concentrate is not detected from the first concentrate sensor 42. If the concentrate is detected from the first concentrate sensor 42, the heating element 66 and the compressor 60 continue to operate even if the second concentrate sensor 54 does not detect the concentrate.

When the filtration of the concentrate is completed by the above process, the microcomputer 86 opens the solenoid valve 110 of the washing apparatus so that the purified washing water is supplied into the filtration member 30 and the compressor ( 60). When the compressor 60 is operated while supplying the washing water in this way, the washing water is forced through the filter paper 32 to wash the filter paper 32. Therefore, the washing water washes the inside of the filter paper 32 and the body 10 as well as the inside of the filtration member 30.

Subsequently, the washing water that has been washed is discharged through a separate discharge pipe or discharged through the concentrate discharge pipe 50 to wash the inside thereof.

The microcomputer 86 may open the solenoid valve 110 only for a set time, and operate the compressor 60 so that washing is performed only for a set time, or a predetermined amount of washing water may be supplied.

On the other hand, if the user has selected the manual mode, the control unit 80 is configured such that each process can be performed by operation of the manual button.

That is, when the filtration button is operated among the control buttons of the control panel (not shown), the microcomputer 86 operates the compressor 60 and the heating element 66 to supply the heated compressed air to the filtration member 30. This compressed air is pressurized to force the supplied concentrate to pass through the filter paper 32.

When the filtration is completed in this process, the user operates the discharge button again to open the discharge valve 52 for discharging the filtered concentrate. At this time, the discharge pump 56 may be operated.

Subsequently, when the user operates the washing button, the microcomputer 86 opens the solenoid valve 110 so that the washing water is supplied to the filtration member 30 and simultaneously operates the compressor 60 so that the compressed air is operated. The filter paper 30 is supplied into the filter member 30 to wash the filter paper 32 and the filter member 30 while the washing water is forced through the filter paper 32.

In this way, the user can manually select each process.

3 to 4 show a second embodiment of the present invention.

As shown in FIGS. 2 to 4, in the filtration apparatus according to the second embodiment, a vacuum pump 90 is used instead of the compressor 60, and an air discharge pipe 92 is used instead of the compressed air supply pipe 70. , The heating element 66 is deleted, the air temperature sensor 67 is deleted, and has the same configuration as the first embodiment except that the air inlet valve 94 is used instead of the air discharge valve 26. .

That is, the filtration device according to the second embodiment is a vacuum pump 90 installed inside the case 14, one end is installed in the vacuum pump 90, the other end penetrates the upper cover member 12A. And an air inlet valve (92) installed in the door (20) to introduce external air when the pressure inside the filtration member (30) is below a set pressure. A first concentrate sensor 42 for detecting whether the concentrate is supplied or not, and a second concentrate sensor 54 for detecting whether the concentrate is discharged; The control unit 80 and the control unit 80 having a microcomputer 84 for generating a control signal based on each detection signal of the detection unit 82.

Therefore, the microcomputer 86 of the controller 80 drives the vacuum pump 90 when the supply of the concentrate solution is detected from the first concentrate sensor 42 to discharge the air inside the body 10 to the outside. . As such, when the air inside the body 10 is discharged to the outside through the air discharge pipe 92 and the vacuum pump 90, the pressure inside the body 10 is lowered, and thus into the filtration member 30 Concentrated liquid was forced to pass through the filter paper 32 to move into the lower pressure body (10). In this process the concentrate is filtered.

When the discharge pump 56 is operated in this state, the concentrated liquid filtered while passing through the filter paper 32 is discharged to the packing machine through the concentrated liquid discharge pipe 50.

That is, the vacuum pump 90 discharges the air inside the body 10 to lower the pressure, so that the liquid (concentrate) inside the relatively high pressure filter member 30 is forced through the filter paper 32. The lower pressure is to move into the body (10).

In this process, the concentrated liquid in the filtering member 30 is filtered while forcibly passing through the filter paper 32, and the filtered concentrated liquid is discharged to the outside by the discharge pump 56.

At this time, the control unit 80 may perform the operation of filtering and discharging the concentrate according to the user's operation is made automatically or by manual operation.
