DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pickle liquid defoaming apparatus which is used by being interposed in a pickle liquid circulation path of a pickle liquid injection device for injecting a pickle liquid into raw meat of processed meat food such as ham.

[0002]

2. Description of the Related Art Generally, when producing processed meat foods such as ham, a pickle solution composed of an aqueous solution of starch, salt or the like is injected into the raw meat soul to improve the preservability.
FIG. 3 is a block diagram of a pickle liquid injecting apparatus for injecting the pickle liquid into the raw meat soul. As shown in this figure, the collection tank 1 is
Is supplied to the injector needle 3 through the injection line 21 by the feed pump 2 and is injected into the raw material by the injector needle 3.
At this time, the pickle liquid not injected is returned to the return line 22.
Is returned to the collection tank 1 as a return pickle liquid. The reduced amount of the pickle liquid after the injection is replenished through the pickle liquid replenishment line 23.

[0003] As described above, the pickle liquid is circulated, and during this circulation, bubbles may be mixed into the pickle liquid. In particular, the injector needle 3 is configured to diffuse the pickle liquid in order to evenly inject the pickle liquid into the raw material soul, and therefore, air bubbles are easily mixed in the unpickled pickle liquid, If this is returned to the collection tank 1 as a return pickle liquid and reused, the following inconveniences occur and have been a problem.

That is, if the pickle liquid is injected into the raw material soul in a state where the air bubbles are mixed, the raw material soul embraces the air bubbles inside. Therefore, if a slice vacuum pack or the like is applied in this state and commercialized, the raw meat chunks are shipped with air bubbles contained therein, and there has been a problem that the commercial value is significantly impaired. Further, as the operation time of the injection device becomes longer, the amount of bubbles mixed into the pickle liquid also increases. That is,
Since the specific gravity of the pickle liquid is low, the amount of the pickle liquid injected into the raw material meat changes between the initial operation and the end of operation, and there is a problem that the quality of the product is not constant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. FIG.
1 is a block diagram of a pickle liquid injection device incorporating a pickle liquid defoaming device according to the present embodiment. As shown in FIG. 1, the pickle liquid defoaming apparatus according to the present embodiment includes a storage tank 4 connected to the recovery tank 1 via a connection line 24, and a vacuum pump 7 for reducing the pressure inside the storage tank 4.
A piston pump 10 that circulates pickle liquid between the collection tank 1 and the storage tank 4 via a connection line 24 and a return line 25; and a gaseous phase of the storage tank 4 that is provided in the upper part of the storage tank 4. A first pressure sensor 5 for detecting the pressure Pa of the portion 4a, a second pressure sensor 6 provided at a lower portion in the storage tank 4 for detecting the pressure Pb of the liquid phase portion 4b in the storage tank 4, A pressure adjusting device 8 for displaying the pressure in the storage tank 4 based on the output signal from the pressure sensor 5 and for arbitrarily setting the pressure range of the gas phase portion 4a of the storage tank; a first pressure sensor 5 and a second pressure; There is provided a liquid amount adjusting device 9 for displaying the liquid amount in the storage tank 4 based on the difference between the output signals from the sensor 6 and for arbitrarily setting the liquid amount range. The connection line 2
4 is provided with a control valve 13. Further, the control valve 15 and the check valve 16 are provided in the return line 25, and the vacuum pump 7
A check valve 14 is provided in a connection line between the pump and the storage tank 4 to control the flow of the pickle liquid.

In order to continuously remove bubbles from the pickle liquid with good controllability, the degree of vacuum in the storage tank 4 is controlled and the amount of pickle liquid stored in the storage tank 4, that is, the liquid level is controlled. Although it is necessary to perform the control, the pickle liquid defoaming apparatus according to the present embodiment can perform such control automatically and with good controllability.

First, the principle of controlling the degree of vacuum in the storage tank 4 will be described. The pressure Pa of the gas phase portion 4 a in the storage tank 4 is reduced by the vacuum pump 7. The first pressure sensor 5 detects the pressure Pa and outputs an electric signal corresponding to the detected pressure to the pressure adjusting device 8. This electric signal changes according to the pressure change, for example, 0.000 Kg / c.
4 mA corresponding to m2 (complete vacuum pressure) to 1.033 Kg / cm2 (standard atmospheric pressure) to 1.200 Kg / cm2
A current of ２０20 mA to 22.59 mA can be output in proportion. Then, the pressure adjusting device 8 converts the input signal into a pressure value and displays the pressure value of the pressure Pa.
As described above, the pressure adjusting device 8 can set an arbitrary pressure range, and outputs a control signal to the vacuum pump 7 so that the pressure Pa is maintained within the set pressure range. That is, the pressure P
When a exceeds the upper limit of the setting range, an operation start signal is output to the vacuum pump 7, and when the pressure Pa falls below the lower limit of the setting range, an operation stop signal is output to the vacuum pump 7. Thus, the degree of vacuum in the storage tank 4 is automatically adjusted.

Next, the principle of controlling the amount of liquid in the storage tank 4 will be described. The detection pressure P1 of the first pressure sensor 5 is the pressure Pa of the gas phase portion 4a of the storage tank 4, and the detection pressure P2 of the second pressure sensor 6 is the sum of Pa and the head pressure of the pickle liquid, that is, Pa + Pb. . Therefore, P2-P1
Is calculated, the head pressure Pb can be obtained, whereby the liquid level position (liquid amount) of the storage tank 4 can be known.

Specifically, the liquid amount is controlled as follows. That is, the first and second pressure sensors 5 and 6 output electric signals corresponding to the respective detected pressures P1 and P2 to the liquid amount adjusting device 9. According to the conversion rate of the electric signal output from the first pressure sensor 5 to the pressure adjusting device 8 described above, the first pressure sensor 5 is 0.000 kg / cm 2 (complete vacuum pressure) to 1.033 kg / cm 2 (standard size). Atmospheric pressure) ~ 1.2
4 mA to 20 mA to 2 corresponding to 00 kg / cm 2
The second pressure sensor 6 outputs a current of 2.59 mA and outputs a current of 0.29 mA.
000Kg / cm2 (complete vacuum pressure and no pickle liquid)-0.062Kg / cm2 (complete vacuum pressure and maximum pickle liquid level)-1.033Kg / cm2 (standard atmospheric pressure and no pickle liquid)-1.095Kg / cm2 4 mA to 4.96 mA to 20 mA to 22.96 mA corresponding to the detection pressure of (standard atmospheric pressure and highest level of the pickle liquid)
Output current. Then, the liquid amount adjusting device 9 outputs the respective electric signals, that is, 4 mA to 20 mA to 22.59 mA.
And 4 mA to 4.96 mA to 20 mA to 22.96 mA
Is the corresponding liquid level length, that is, 0 cm to 1033 cm
1200cm and 0cm ~ 62cm ~ 1033cm ~ 1
It converts to 095 cm and calculates P2-P1 to display the range of 0 cm to 62 cm as the liquid level length of the pickle liquid. Note that 62 cm corresponds to the depth of the storage tank.

Further, as described above, the liquid amount adjusting device 9 can set an arbitrary liquid amount range, and controls the control valve 13 so that the liquid level of the pickle liquid in the storage tank 4 is maintained within the set range. Control opening and closing. That is, the liquid amount adjusting device 9 outputs an open signal to the control valve 13 when the liquid amount of the pickle liquid becomes lower than the lower limit of the set range. The control valve 13 is opened by this open signal. Since the pressure Pa in the storage tank 4 is set to be equal to or lower than the atmospheric pressure, the storage tank 4 is moved from the collection tank 1 by suction pressure.
The pickle liquid is sucked into. Then, when the amount of the pickle liquid becomes higher than the upper limit of the set range, a close signal is output to the control valve 13. The control valve 13 is closed by this closing signal, and the supply of the pickle liquid to the storage tank 4 is cut off.
Thus, the amount of the pickle liquid in the storage tank 4 is automatically adjusted.

The flow of the pickle liquid from the storage tank 4 to the recovery tank 1 is performed as follows. That is, the control valve 15 is opened and the pickle liquid is fed into the piston pump 10 until the piston of the piston pump 10 shifts from the forward position to the backward position in the cylinder. Then, until the piston of the piston pump 10 shifts from the retracted position to the advanced position in the cylinder, the control valve 15 is closed, and the pickle liquid in the piston pump 10 is returned to the collection tank 1 via the check valve 16.

According to such a pickle liquid defoaming apparatus according to the present embodiment, it can be used by being incorporated in a pickle liquid injecting apparatus for injecting the pickle liquid into the raw meat. While the defoaming of the pickle liquid can be performed continuously, it is possible to effectively prevent air bubbles from being mixed into the raw material soul, and it is possible to keep the injection amount of the pickle liquid constant for a long time. .

Further, according to this embodiment, the level control of the pickle liquid in the storage tank is performed by using two pressure sensors, so that a float switch, an electrode rod, an ultrasonic sensor, and the like are used. In this case, problems such as strength problems and malfunctions that occur when liquid level control is performed are less likely to occur. Further, in the case of the control for detecting the liquid level in the storage tank in a depressurized state, bubbles are generated on the liquid surface portion by defoaming, whereby it is not possible to know an accurate liquid level, but in the present embodiment, Since the liquid level of the pickle liquid is controlled by the head pressure of the pickle liquid, such a problem does not occur, and the amount of the pickle liquid can be accurately controlled.

The connection pipe 44 from the recovery tank 1 to the inside of the storage tank 4 is preferably attached in a direction tangential to the inner peripheral wall of the storage tank 4. In the present embodiment, as shown in FIG. 2, a cylindrical storage tank 4 is used,
The connection pipe 44 is attached in the tangential direction of the inner peripheral wall, that is, in the tangential direction of the cylindrical portion. Thereby, the pickle liquid sucked into the storage tank 4 can be swirled on the inner wall surface of the tank, and the liquid surface area can be widened and the deaeration effect can be increased.

Further, in the present embodiment, the storage tank 4 has a double structure, and the inner peripheral wall 41 and the outer peripheral wall 42
Is filled with a catalyst such as antifreeze. Usually, the pickle liquid is injected at a low temperature. However, according to the storage tank 4 according to the present embodiment, such a double structure is employed, so that the pickle liquid can be effectively prevented from absorbing heat and raising the temperature. Can be. Further, a pressure error caused by a temperature change in the storage tank 4 can also be prevented.
