The present invention discloses instant porridge potato chips which are cooked. The thicknesses of the potato chips are more than 0.01 mm and less than 1 mm, the lengths of the potato chips are less than 10 mm, the widths of the potato chips are less than 8 mm, and the water contents of the potato chips are more than 1% and less than 10%. The potato chips are instant foods. A production method is as follows: the potatoes are washed clean, the washed potatoes are 
cut into thick potato slices, the thick potato slices are cured, the cured thick potato slices are dried, the dried thick potato slices are 
cut into potato granules using a granule 
slicing machine, the potato granules are rolled into dried potato slices, the dried potato slices are dried, the dried potato slices are sterilized, and the sterilized dried potato slices are packaged. The granule 
slicing machine consists of an upper body and a 
lower body, rotary cutters, a rotary cutter beam, a core table, a 
pile base, a motor and a motor house. The lower mouth of the upper body and the upper mouth of the 
lower body have the same 
diameter and are connected and located using a 
flange, the upper part of the core table is in a round pie shape, the lower part of the core table is a straight cylinder and inserted into and fixed to the 
pile base, the 
pile base is supported in the 
lower body to enable the core table, upper and lower bodies, and motor in a same shaft axis, the 
diameter of the lower mouth of the upper body is larger than the 
diameter of the large diameter of the upper part of the core table, and the height of the lower mouth of the upper body is the same as that of the upper part of the core table, the center of the rotary cutter beam is vertically connected to the lower end of a 
motor shaft in a T-shaped manner and higher than the core table, the rotary cutters are connected to the two end heads of the rotary cutter beam in a T-shaped manner, the lower tips of the rotary cutters are inserted into gaps between the lower mouth of the upper body and large diameter of the upper part of the core table, and raw materials enter from the upper body and 
discharge from the lower body.
