The present invention provides a process for the preparation of protein hydrolysate from soy flour, which comprises preparing aqueous slurry of defatted soy flour having 6-12% wv of solid content, hydrolyzing the said slurry using fungal protease at pH 7-8 and temperature 435 C. The combined cleaning fluid and pressurized water diffused with the pressurized air is applied to the object. The application of force to the beads that are secured within the connector results in the release of beads from the internal cavity when the force exceeds a threshold. The controller is configured to capture user inputs based on an output signal produced via capacitive coupling of the at least one drive electrode of the electrode base, via the code wheel, to the respective sense electrodes of the electrode base. In each dual gear plane, at least one idler gear is used for two gears. The output circuit is operable to produce an output voltage.
