A pneumatic pressure pulse cleaning machine includes a container body, which has a rear side to which a container cover is rotatably mounted and also has an interior space in which a pipe assembly that includes pipes connected together to form a grating configuration is received. The pipe assembly has a plurality of through holes formed therein and facing upwards. A support board is received in the interior space and arranged above the pipe assembly so that an article disposition zone is provided in the container body above the support board. The pipe assembly includes a joint, which is connectable with a tube for connection with a pneumatic pressure source. Articles to be washed are positioned on the support board. The pneumatic pressure source is activated to generate pneumatic pressure pulses that are ejected through the through holes to impinge and thus clean the articles.

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.

Various embodiments relate to a manual centrifuge food processing device. An example device includes a bowl and a spindle extending from an inner surface of the bowl. A mesh basket is removably coupled to the bowl and is structured to receive a food product. The mesh basket defines a hub structured to receive the spindle so as to facilitate rotation of the mesh basket relative to the bowl about the spindle. A lid is removably coupled to the bowl. The lid includes a drive mechanism structured to rotate the mesh basket in response to a manual input so as to drive liquid from the food product due to centrifugal force. Each of the bowl and the mesh basket is formed of metal.
