Auto straining apparatus

Disclosed is a straining machine which uses centrifugal force generated by the rotation of the bottomed cylindrical container having a filtration hole in the circumferential side surfaces, the clogging of even filtration through hole while maintaining foodstuffs pressing pressure and duration optimally eliminated, providing a driving method and an automatic straining device optimally sustainable straining machine straining action. A and around the rotatably supported by the circumferential side plate vertical bottomed cylindrical container which is filtration through holes bored in the central axis, in the inner circumferential side plate inner peripheral surface of the bottomed cylindrical container capturing a filtrate collecting emitted filtrate to rotatably and supported rotating presser, outside the container from the filtration through hole of the bottomed cylindrical container around the contact or close to being the central axis and a collecting member, while the bottomed cylindrical container straining object is turned to a predetermined rotating direction is rotated at a first rotational speed, the rotational pushing element to the bottomed cylindrical container in the same rotational direction When comprising the step of rotating at a second rotational speed with a predetermined speed difference between the first rotational speed. .FIELD 8
