The utility model discloses a device for separating kitchen residual food from oil and water. The device comprises a box body, a first separating structure, a second separating structure, a third separating structure and a fourth separating structure, wherein the first separating structure is arranged on the box body and used for separating oil and water in the collected residual food on a dining table from the food; the second separation structure is used for separating
grease in the oil-containing water separated by the first separation structure from
sewage; the
grease discharging structure is used for collecting and discharging
grease in the oily water; and the blow-off
pipe is used for discharging the
sewage separated by the second separation structure. The kitchen residual food and oil-water separation device is simple in structure, convenient to use, low in
energy consumption, clean, environment-friendly, capable of fully separating oil-containing water and grease in the oil-containing water from
sewage in the residual food on a dining table, high in separation speed, capable of automatically discharging the grease in the oil-containing water, convenient to collect and reuse the grease and capable of saving energy. The residual
food processing cost and the equipment
purchasing and maintaining cost are reduced, and the residual
food processing efficiency is improved.
