A ball-shaped food forming machine, which is adapted to cut a food slug to form ball-shaped foods, comprising
- a casing, having a receiving chamber where the food slug is adapted to be placed in;
- a pair of sheet-forming rollers, rotatably disposed in the casing, wherein a sheet-forming gap is defined between the pair of sheet-forming rollers, the sheet-forming gap is communicated with the receiving chamber in a manner that the food slug placed in the receiving chamber is able to be pressed to form a food sheet;
- a sheet guide, fixed in the casing and having a cutting end, wherein the sheet guide is adapted to guide the food sheet from the sheet-forming gap to the cutting end;
- a cutter roller, rotatably disposed in the casing;
- a cutter blade, disposed on the cutter roller, the cutter blade being drivable by the cutter roller to rotate about an axis of the cutter roller;
- when the cutter blade rotates to a first position, a distal end of the cutter blade is right adjacent to the cutting end of the sheet guide in a manner that the food sheet is able to be cut into food strips;
- a first ball-forming roller, rotatably disposed in the casing, wherein the first ball-forming roller includes a wavy surface having a plurality of annular first peaks and a plurality of annular first valleys, each of the first valleys is between two of the adjacent first peaks;
- and
- a second ball-forming roller, rotatably disposed in the casing, wherein the second ball-forming roller includes another wavy surface having a plurality of annular second peaks and a plurality of annular second valleys, each of the second valleys is between two of the adjacent second peaks, the first peaks are respectively corresponding to the second peaks while the first valleys are respectively corresponding to the second valleys, a plurality of ball-forming gaps are defined between the first ball-forming roller and the second ball-forming roller, the first peaks are right adjacent to the corresponding second peaks respectively, the first ball-forming roller is closer to the cutter blade than the second ball-forming roller;
- wherein the first ball-forming roller and the second ball-forming roller are adapted to further cut and press the food strips cut by the cutter blade through the ball-forming gaps to form a plurality of ball-shaped foods;
- wherein the cutter blade and the first ball-forming roller are disposed without any food-strip-transporting component disposed therebetween;
- wherein the width of the sheet-forming gap is D1, a shortest distance between the distal end of the cutter blade and the first peaks is D2 when the cutting blade rotates to a second position, wherein the ball-shaped food forming machine satisfies the following relation:
- D2/D1<1.5.
