การลดการดูดซับน้ำมันในผลิตภัณฑ์แห้วทอดด้วยเทคโนโลยีสนามไฟฟ้า

This research is studying of an electric field combine with a frying process in a Chinese water chestnut product for reducing oil absorb. An electric field that is used in an experiment will have a stress from 1-3 kV/cm. This will be generated by using a direct current high Voltage from 1066 to 3200 V. which is distributed to an electrode in an uniform and non-uniform of an electric field. This will have a dielectric barrier discharge. There is an analysis for finding a relationship of a moisture on absorbing oil of a Chinese water chestnut fried product due to a moisture has an effect on absorbing oil directly. From an experimental result this is found that the best electric field stress which will have an effect on reducing a moisture of a Chinese water chestnut is an non-uniform electric field form that is created from a direct current high voltage at 3200 V. and this will have an electric field stress at 3 kV/cm. This will have an average of a difference of a moisture at 0.6 g. This will select to use a direct current non-uniform electric field at 3 kV/cm. In an experiment combine with a fried process in a Chinese water chestnuts fried product this is done for reducing of absorbing oil. By this will fry at the temperature of 180๐C for 5 minutes. This is found that this can reduce an absorbing of oil best at 17.93% when this has compared to a Chinese water chestnuts fried that hasn’t passed an electric field.

The experimental models of electric fields were set up by using 4 forms of electric poles a point - point point - rod parallel rod and coaxial ring. The equipotential lines and electric line of force were drawn by using Microsoft Office Visio Program 2007. The drawing of equipotential lines and electric field had shown the direction of electric field moving from the positive electrode toward the negative electrode and perpendicular to the equipotential line. The point - point poles in 10 cm. distance have constant and the highest electric fields which is 28.64 V/m. The electric fields of point - rod parallel rod and coaxial ring are 60.51 V/m 45.81 V/m and 181.98 V/m respectively.
