Abstract

PROBLEM TO BE SOLVED: To provide a two-layer type fryer using oil and water, which is enabled to save labors for washing the fryer and to automate the water monitoring by providing means for adding a function to discharge fry dregs having fallen into the water.SOLUTION: When water containing dregs is discharged, the dregs are not allowed to reside at a certain portion and water is replaced at a predetermined time interval so that dregs may not clog when discharged. At this replacement, supply and discharge of the water are balanced, and weak water flows are generated from a water supply port 203 to a discharge valve 210 so that the fry dregs having fallen into the water are discharged on a water flow simultaneously as the water is replaced.

Description

A system that automates water exchange easily and inexpensively by adding to the equipment currently on sale for deep-fried food containers with water under tempura oil

The device currently sold and popular is that the deep-fried rice cake that has fallen into the water is drained once a day, draining the water, and then removing the water to wash away the straw. Realize the exchange.
The flyer technique that separates and collects the fried rice cake without using the driving device disclosed in Patent Document 1 is difficult to put into practical use and has not been put into practical use.
There is a problem with the strength of the vortex of the water in contact with the oil surface, the problem of oil entrainment and the soot in the pool are balanced with the water stream, and so there is a problem that soot is not discharged well (clogging).
The water circulation type fryer disclosed in Patent Document 2 has a complicated structure and is expensive.

In addition, the deep-fried food has moisture, and water increases when many deep-fried foods are processed.
If water increases extremely with respect to oil, water will become near a heater part, the temperature of water will rise, and the worst will be a steam explosion.

When processing many deep-fried foods, it is always necessary to monitor the position of the water.
A means to solve these problems is provided.

Japanese Patent Laid-Open No. 2010-172777 JP 2009-238797A JP 2007-275145 A JP 2005-102783 A

An oil and water two-layer fryer that is already sold and widely used can be easily added to provide an automated structure for water exchange.
Water supply, temperature, and water sensors are inserted into the top of the fryer from the top of the fryer to perform water exchange and water management.
A water inlet will be installed in the center of the back of the fryer to generate dredged water flow.
The water flow is a water flow that does not involve oil and is generated toward the drain valve to increase the effect of dredging.

It is a system to be added, and to provide a structure that can be easily added and the soot is efficiently discharged to the discharge valve.
In the technology that has already been provided, the sedimentation tank, oil tank, water tank, various valves, and piping are complicatedly configured, causing failure such as clogging.
In addition, (Patent Document 1) When using a water flow and discharging the soot, simply using the water flow, depending on the difference in water pressure depending on the water supply at the installation site, entrain oil in the case of strong (oil emulsifies), When it was too weak, there was a defect that the fried rice cake was not discharged.
For this purpose, the water pressure is set at a manual valve (also adjusting the 203 water supply point) to a water pressure at which soot is discharged without oil being caught (check with the discharged water) and stabilized.
In addition, when a discharge valve having a large diameter is used, if the opening control is not performed, the balance with the water supply (water level) is lost and the oil level is lowered, so that the work cannot be performed.
Providing the finished product will increase the price, but it can be provided at a low price and the service can be easily handled even in the event of a failure.

A water supply pipe is installed in the water tank, and the water flow of the water tank does not entrain the oil in contact with the surface of the water. The optimal water supply point (adjustable with the height and position of the water supply pipe), water is supplied with adjusted water pressure, and the water tank After the feed water flow is stable (several seconds), drain the water by opening the drain valve halfway. The drain valve is controlled by adjusting the water level with the water level sensor.
The water supply continues unless the water level sensor detects the water level or high level.
If the balance between water supply and drainage is poor, the oil level will fluctuate and work will not be possible, so the accuracy of the oil level sensor is important.
The sensor is equipped with a number of water level sensors that can judge about 5MM, which does not cause anxiety even if the oil level fluctuates.
The water flow generates a weak water flow that does not entrain oil toward the drain valve.
The drainage is about three times larger than the water supply, and the amount of drainage is large, so the drainage is half open (control can be set finely) and opened and closed repeatedly.
The water flow is an oil surface, a water flow in contact with the water surface, and four or more weak water flows that have fallen to the bottom of the water tank and involve a fried rice cake and do not involve oil.
The fried rice cake does not stay in one place (such as a pool), and the fried rice cake on the water flow is discharged with water when the drain valve is opened.
This operation is performed at regular intervals to change the water and simultaneously discharge the soot.

It can be added to the oil and water layer fryer that has already been put into practical use and has already been put into practical use (soot discharge is not automated) to automate water exchange.
Daily water exchange and cleaning operations are automated, saving labor.
Water management is automated, and steam explosions can be monitored and eliminated.

1 and 2 show a first embodiment of the present invention, and FIG. 2 is a side view of the present invention in FIG.

The drain valve is conventionally equipped with an actuator (electric drive unit).
The drain valve control unit 210 in FIG. 2 (109 in FIG. 1) includes a power supply unit and a microcomputer board. The drain valve has a structure that can be controlled to close and open at 90 degrees, and the actuator has a position sensor that can control the opening degree of 30, 60, and 90 degrees.
2, 203, 204, 211, 213, 214, 215 are inserted from the upper part of the fryer, and 202 is a sensor unit, which is installed on the boundary surface between the oil tank and the water tank. It is connected to 210 via the 211 solenoid valve control unit in FIG. Sensor information is connected to the microcomputer board via communication. There is a water exchange push button 210, and when this button is pressed, water exchange is started. If it is not pressed, it will start automatically at a certain time. This can be adjusted with the set button.
The 214 water connection port is connected to the water supply. Set the 213 water manual valve half open.
When the water exchange mode is entered, the electromagnetic valve 211 in FIG. 22 is opened to start water supply. Water is supplied to the water tank from the upper water supply pipe 203 and the lower water supply pipe 204.
Since the 202 water level sensor can observe two or more water levels, many cases are detected when the water level is appropriate.
When appropriate, drainage begins after a few seconds when the water flow stabilizes when water supply begins.
The 203 upper water supply generates the water flow shown in FIGS. 2207 and 208 that entrains the fried rice cake at the contact surface between the oil surface and the water tank.
Observe the drainage and adjust the 213 water supply manual valve to adjust the strength of the water flow so that it does not involve oil and adjusts to a water flow strength that discharges a lot of soot.
Once adjusted, this does not need to be adjusted if the water strength is stable.
Discharge starts automatically at 30 degrees, 30% of the opening degree adjustment by the microcomputer software, and closes when the sensor is no longer suitable.
Open again as appropriate. If the appropriate time is longer than a certain time, increase the degree of opening.
This operation is paused for about 30-40 seconds and then repeated for about 5 seconds. Repeat about 5 times (corresponding to the amount of water in the tank). The water in the aquarium is replaced with new water, and the trough is placed on the 207,208 water flow and simultaneously discharged from the 206 drainage port.
Filter the gutters through the net to the outside and drain only the water into the sewage.

It is a top view of Example 1 of the present invention. FIG. 2 is a side view of the present invention of FIG. 1.

Claims (3)

In a two-layer fryer that uses oil and water, the fried rice cake that has fallen into the water is supplied to the aquarium and at the same time a plurality of water flows are generated at the time of water supply, the fried rice cake is placed on this water flow and the water flow is directed to the discharge valve The water should be changed at the same time as the water is discharged. In order to keep the water level constant, the opening / closing degree of the discharge valve should be controlled to balance water supply and drainage. As a water exchange system, the water exchange function of the two-layer flyer should be integrated, separated from the normal flyer function, to maintain the minimum function as a flyer in case of failure and to simplify the service.
