Abstract: An appliance, system, and method for operating an appliance and determining presence of water softener at water provided to an appliance is provided. The system is configured to obtain a first water hardness value; obtain a second water hardness value based on a location of the appliance; determine a ratio of the first water hardness value and the second water hardness value; compare the ratio of the first water hardness value and the second water hardness value to a threshold limit; transmit a first water hardness signal when the threshold limit is exceeded, wherein the first water hardness signal corresponds to the first water hardness value; transmit, to the database storage device, a second water hardness signal when the ratio is within the threshold limit; and adjust operation of the appliance based on whether the first water hardness signal or the second water hardness signal is transmitted.

Abstract: An appliance, system, and method for operating an appliance is provided. The appliance, system, and method include performing a wash cycle and draining wash water from the wash chamber, flowing a quantity of water to a wash chamber, determining a water hardness value based on a water conductivity measurement and a temperature measurement, and draining the quantity of water from the wash chamber.

Abstract: A dryer appliance and a method of operating a dryer appliance are provided. The dryer includes a drum defining a drying chamber rotatably mounted within a cabinet, an additive dispensing assembly to provide a dryer additive to the drying chamber, and a controller for initiating a drying operation. The controller obtains washer operating parameters from a washing machine, determines a drying operation based on the received parameters, initiates a dry cycle, and directs a dryer additive to be dispensed based on the dryer operating schedule.

Abstract: A method of operating a washing machine appliance includes measuring a humidity value with the humidity sensor and comparing the measured humidity value to an expected humidity value. The method also includes flagging a fault in response to the measured humidity value differing from the expected humidity value by at least a predetermined threshold.

Abstract: Provided are a method of concentrating protein in grain powder, grain powder including protein that has been concentrated by using the method, and a feed additive including the grain powder including concentrated protein. According to the method of concentrating protein in grain powder, grain powder is treated with enzyme to increase the water-soluble saccharide content in a source, and by inoculating bacteria or yeast and fermentation, the increased water-soluble saccharide is removed, leading to a higher concentration of protein. Thus, the protein content ratio increase effects and the function of grain powder as a protein source are enhanced.

Abstract: The present invention relates to a method for separating protein from food by using an iso-electric point precipitation, comprising: obtaining a protein extract by adjusting pH of a raw material food in a media; precipitating the protein by adjusting pH of the protein extract to an iso-electric point of the desired protein; and recovering the protein precipitated after separating a protein filtrate through centrifuging the precipitated protein; in which the method may further include a heat-precipitation of the protein by heating the protein extract or the protein filtrate to 60˜145° C. The protein obtained in high yield according to the above method can be used as a food additive or a food nutritional enhancer.
