Hereinafter, the operation and effect of the food processing apparatus using the high voltage weak current of the present invention having the above configuration will be described.

According to the present invention, when the device is operated, the transformer 20 modulates the AC power received from the primary coil 24 by an electromagnetic induction action to supply a desired current to the secondary coil 26. Therefore, the impedance is converted and the weak waveform is obtained to output the desired weak current through the resistor 27 to the output terminal 29 of the secondary coil 26.

Since the output terminal 29 is connected to the current carrying plate 320 of the frying vessel 200, the current carrying plate 320 always generates a high punch pressure weak current of about 10 kΩ and 10 kW. Is discharged in the frying vessel 200. At this time, the weak current discharged is very weak in progress and reaches its reach, that is, the current forming band is about 200 mm.

Table 1 is a table that tested the acid value, peroxide value, carbonyl value in the frying vessel 200 of the present invention. This is the result of testing the change of the composition in the oil which changes with time by applying an electric current to the said electricity supply board 320 using the high voltage weak current generator 1 of this invention.

The test method is based on the standard maintenance test method [carbonyl value (absorbance per 1g of test data)], and the test specifications are as follows.

(1) Maintenance test: soy salad oil 27ℓ / 27.3㎏

(2) Tempura container: 30ℓ medium heating direct fire table oil container

(3) Applied voltage: 10㎸, current 100㎃

(4) Surface Area: 1,760㎠

(5) Temperature: 150 ± 2 ℃

(6) Water injection amount: 300㏄ at 2 hour intervals (6.2g water / ㎏ oil / Hr)

(7) Air connection area: (72㎠ / oil ㎏)

In addition, the acid value at the time of oil exchange standard reached 2.0.

As described above, in the fryer using the high voltage weak current of the present invention, the high voltage feeble current is always generated in the cooking oil so that the acid value 2.0, which is referred to as the replacement time of the frying oil, or the increase of the peroxide and carbonyl levels are increased. By suppressing it, it becomes possible to save cooking oil by delaying the exchange time of cooking oil.

Therefore, since frying oil can be used for a long time, it is very effective in reducing waste flow rate and improving working environment.

See the graphs of FIGS. 6 (a) and 6 (b). In these graphs, the fryer of the present invention was operated for 10 hours a day to compare the acid value of the cooking oil in the fryer and the acid value according to the evaporation of water in the frying oil.

As can be seen from these graphs, the time to reach the acid value 2.0, which is the point of cooking oil replacement, was within 100 hours in the past (sharp curve), but the impulse frying vessel equipped with the high voltage weak current generator 1 of the present invention ( In the case of 200), acid value 2.0 is reached (curved line) in 500 hours, and the moisture contained in the food ingredients is removed from the food and mixed with cooking oil during frying. In order to test the acid value due to the evaporation of water, a water spray test in which water was forcibly sprayed on cooking oil, the conventional oil had to be replaced at 35 hours, but in the case of the impulse type of the present invention, 200 hours When the acid value was reached, the acid value was only 1.0. From this result, in the present invention, the time for reaching the acid value 2.0 becomes long, and the time for cooking oil to become waste oil. By extending the time, it is possible to save the material, to reduce the amount of waste oil generated and to uniform the taste of the fried food.

When the power is turned on to operate the device, the weak current flows through the current carrying materials 450 and 452, and the high voltage weak current flows in the corresponding food material in the container body 410.

Therefore, the stored food material is minutely pulsated by the high voltage weak current generated in the high voltage weak current generators 1 and 1A, and consequently suppresses propagation of various germs. The present invention can be used in a refrigerator.
