The invention discloses dry raw potato granules of which the granular sizes are larger than 0.1
millimeter and smaller than 30 millimeters and the water contents are higher than 1% and lower than 10%; and the prepared dry raw potato granules are convenient to store. The dry raw potato granules are cheap nutritious and health-care staple-food-like
food products which can be cooked as whole potato granules or in a mixture with rice, or used for other purposes. The
slicing and dicing
machine for preparing the dry raw potato granules is composed of the following components: an upper body, a
lower body, rotary cutters, a rotary cutter crossbeam, a core worktable, a
pile base, an
electric motor and an
electric motor room; the upper body is shaped like a hopper; the
lower body is a cone-shaped
barrel; the lower opening of the upper body and the upper opening of the
lower body are identical in diameters, but the lower opening of the upper body is the smallest; the upper body and the lower body are connected and positioned by a
flange; the core worktable is formed by connection of the upper part and the lower part; the upper part of the core worktable is shaped like a round cake, and the lower part of the core worktable is a right circular cylinder which is inserted and fixed in the
pile base; the
pile base is supported in the lower body by using radial ribs, and makes the core worktable, the upper body, the lower body and the
electric motor coaxial; the height of the upper
circular surface of the major
diameter of the core worktable is identical to the heights of the upper body and the lower body; the lower
caliber of the upper body is larger than the major
diameter of the core worktable; the center of the rotary cutter crossbeam is perpendicularly connected to the lower end of the electric
motor shaft in T-shaped state; the rotary cutter crossbeam is higher than the top of the upper part of the core worktable; the rotary cutters are respectively connected to the two end heads of the rotary cutter crossbeam in T-shaped state; the lower tips of the rotary cutters are inserted in a gap between the lower opening of the upper body and the major
diameter of the core worktable; and the raw materials are fed through the upper opening of the upper body, and prepared materials are discharged through the bottom opening of the lower body.
