    摘要: A method for cleaning fruit and vegetable ingredients is provided, in which the washing basket assembly agitates the water in the washing barrel to rotate upward to achieve the cleaning of fruit and vegetable. During the process of “cyclic cleaning in the barrel”, the drainage outlet in the center of the bottom of the washing barrel is closed to prevent the water from flowing out of the barrel cavity; when the drainage outlet in the center of the bottom of the washing barrel is opened and drained, the water body rotates to form eddy current drainage; fruits and vegetables in the washing basket alternately move centripetally and centrifugally. The number of exercises is proportional to the number of washes.

    摘要: Provided is a residual toxicant detection system and a residual toxicant detection method, the residual toxicant detection method including: allowing an aqueous solution containing a residual toxicant to flow into a detection portion including a cavity; providing at a side of the cavity a light containing a specific wavelength range to react with the residual toxicant; receiving the light that passes through the cavity on another side of the cavity, thereby generating a sensing signal; and calculating an amount of change in absorbance of the aqueous solution according to the sensing signal, wherein when the amount of change in absorbance is less than a threshold value, a detection count is accumulated, and when the accumulated detection count is greater than a predetermined value, a detection result is generated. Therefore, whether or not the residual toxicant on the object is cleaned can be determined easily and accurately.
