Latest Patents
One of Rey-Chein Chang's latest patents focuses on the recovery of waste liquid from the production of rice liquor. This process involves recovering waste liquid from the distillation of fermented rice liquor. After filtration, the residue can be transformed into dry feed, while the filtrate, containing about 4-5% crude protein, 1% starch, and 92 wt. % water, is concentrated to reduce the water content to approximately 70-80 wt. %. The filtrate is then dried using a spray dryer, producing nutritious dry feed, with a suitable chelating agent like magnesium hydroxide employed to prevent product clinging on the dryer walls. Another significant patent is the automatic intermittent energization controller of electrostatic precipitators (ESP). This controller includes a CPU that adaptively manages the DC power used to energize the ESP. An opacimeter is mounted to detect the opacity of dust particles flowing through the ESP. The CPU searches through a predetermined table of charge-pause parameter sets until it finds one that maintains the detected opacity level within a tolerable range.
