High voltage electric field drying rate of the main factors
    1 drying rate and voltage relationship
    Telegram from the same case, the electric voltage is higher , the greater the rate of drying .
    If the polar distance of 12cm, voltage 25kv , the evaporation rate of water evaporates faster than natural 14.24% , sodium gluconate solution evaporation rate accelerated 117.1% ; the pole pitch of 12cm, voltage 35kv , the water evaporation evaporate faster than the natural rate of 312.7% , compared with the voltage of 25kv accelerated evaporation rate of 70.3% , sodium gluconate solution accelerated evaporation rates were 266.1% and 68.2% .
    (2) drying rate between the pole pitch
    Drying rate and electric pole pitch of a great relationship , in addition to and paving material thickness are also related.
    Fresh white radish as raw materials for high voltage electric field drying test study , the ambient temperature is between 24-26 ℃ , the material temperature is maintained at between 36-39 ℃ , shop materials area of ​​0.42m2, shop material thickness is 1.5cm when very were taken from 4cm, 6cm, 8cm; shop material thickness of 3cm, pole pitch to take 6cm, 8cm, 10 cm, 12cm for high voltage electric field drying . The results showed that: the material thickness of 15cm and 3cm are measured at polar distance of 6cm when shortest drying time , drying fastest.
    So for the different materials , the choice of parameters in the high pressure applied to the maximum voltage only , and for the choice of pole pitch according to the size and shape of the material , material thickness and spread to select the size of the pole pitch .
    In short , the impact of high voltage electric field drying parameters are: electric voltage , pole pitch , in addition to the effective area of ​​drying , temperature and humidity, ventilation , material properties, etc. .
