Embodiment 1
[0028] Corn starch with a water content of 3% is used as raw material, deionized water is selected, and corn starch milk with a concentration of 30% is prepared at a temperature of 15°C; then it is processed by a high-speed homogenizer, and the speed is set at 300rad / min. After the slurry was treated for 15 minutes, it was set aside; a double electrode with a length of 0.5 mm and a radius of 0.5 mm was installed on the high-voltage pulse electric field device, and 75% ethanol and distilled water were selected in turn to clean the material circulation pipeline in the high-voltage pulse electric field twice; The electric field strength in the fixed device is 20kV / cm, and the electric field frequency is 2000Hz in the working state, standby; in the temperature environment of 15 ℃, adjust the constant current pump of the high-voltage pulse electric field, and keep the corn starch milk and corn starch milk flowing through the high-voltage pulse When the electrode in the electric fiel...
Embodiment 2
[0030]Corn starch with a water content of 5% is used as raw material, tap water is selected, and corn starch milk with a concentration of 36% is prepared at a temperature of 25°C; then it is processed by a high-speed homogenizer, and the speed is set at 320rad / min for high-speed homogenization After 20 minutes, set aside; install the double electrodes with a length of 3.5 mm and a radius of 0.8 mm on the high-voltage pulse electric field device, and use 80% ethanol and distilled water to clean the material circulation pipeline in the high-voltage pulse electric field for 3 times; set the device The electric field strength in the medium is 15kV / cm, and the electric field frequency is 1500Hz in the working state, standby; in the temperature environment of 25 ℃, adjust the constant current pump of the high-voltage pulse electric field, and keep the corn starch milk and corn starch milk flowing through the high-voltage pulse electric field device Under the working condition of cons...
Embodiment 3
[0032] Use corn starch with a water content of 4% as raw material, choose any one in distilled water, and prepare corn starch milk with a concentration of 37% at 22°C; then process it with a high-speed homogenizer, and set the speed at 340rad / min , after 16 minutes of high-speed homogenization treatment, set aside; install the double electrodes with a length of 1.5 mm and a radius of 0.6 mm on the high-voltage pulse electric field device, and successively select 76% ethanol and distilled water to clean the material circulation pipeline in the high-voltage pulse electric field 3 times; set the electric field strength in the device to 50kV / cm, and the electric field frequency to 2500Hz in the working state, standby; in the temperature environment of 22 ℃, adjust the constant current pump of the high-voltage pulse electric field to maintain the milk flow of corn starch milk and corn starch When passing through the inner electrode of the high-voltage pulsed electric field device, t...
