Patent ID: 8082841

Claim:
An automatic squeezing machine comprising: a dome for retaining fruit; a set of blades disposed under the dome for slicing the fruit vertically by pressure and guiding resulting sliced fruit towards a rotating cone supporting the set of blades, the rotating cone for crushing pulp and extracting juice, wherein the rotating cone performs dual movements of rotation and upward and downward displacement such that at a start of a squeezing cycle the rotating cone and the set of blades are at a lowest position and during the squeezing cycle the rotating cone and the set of blades move upwards such that the blades slice the fruit and the rotating cone crushes the pulp, after which the rotating cone and the set of blades move downward for expelling surplus peel by centrifugal force; and a mechanism for moving the rotating cone and the set of blades comprising: a motor for rotating a tubular part; a spindle inside the tubular part, and means for allowing the tubular part and the spindle the tubular part and the spindle to turn together and the spindle to freely move upward and downward, the spindle engaging the rotating cone such that the rotating cone and the spindle rotate and move upward and downward together; a fixed nut fastened onto an end of the spindle, the fixed nut causing the spindle to move upward or downward, depending on the rotation direction of the spindle, to thereby rotate the rotating cone and displace the rotating cone and the supported set of blades upward and downward; and a cylindrical housing for housing and vertically guiding the set of blades, the cylindrical housing having internal walls with insertions engaging the set of blades, for preventing rotation of the set of blades.
