Title: Dryness control device for grain drier of circulation type
Inventor: OZAKI HIROSHI
IPC: F26B17/14
Filed: 1988-02-02
Abstract: PURPOSE:To make it possible to utilize thermal energy effectively and at the same time prevent any unevenness in the drying at the final stage of drying by the constitution of a control device in which the blast volume is increased more than a set blast volume as the moisture which was detected comes near the range of set values of a set finish moisture. CONSTITUTION:Until the moisture detected by moisture detection means S1 comes near the range of set values for a set finish moisture, the blast volume of a blower device 13 is maintained at a set blast volume and drying is carried out efficiently by utilizing the heat generated by a burner 12. And, at the final stage of drying in which the detected moisture comes near the range of set values for the set finish moisture the blast volume is increased to make small the temperature difference between the side of air inlet and side of air discharge of a drying section 5 for suppressing uneven drying. Accordingly it is possible to suppress uneven drying at the final stage of drying by keeping unnecessary discharge of thermal energy in the starting and intermediate stages as low as possible.

IPC: G03G15/02
Filed: 1993-02-12
Abstract: PURPOSE:To make a maximum potential difference between a discharge wire and a shield low and to prevent a leakage phenomenon even in constitution that an alternating current and a direct current are superposed by allowing a self-bias generating element generating self-bias in a shield to intervene in a ground circuit grounding the shield. CONSTITUTION:An AC power source 11 and a DC power source 12 are connected to a corona discharger 4, and a constant-voltage element generating the self-bias, for example, a Zener diode 15 is allowed to intervene in the ground circuit 14 grounding the shield 13. As a Zener diode 15, the diode whose reference voltage is the same as the voltage (a) of the DC power source 12 is selected. Thus, the shield 13 of the discharger 4 has the self bias having the same polarity as the DC voltage (a). As a result, the voltage (a) is cancelled by the self-bias of the shield, and the maximum potential difference between the wire 10 and the shield 13 is only AC voltage (b), thereby preventing the occurrence of leakage.
