1. A food processor comprising:
a tubular member surrounding an axis and including a tubular main body having a first tubular wall located on a rear side thereof and a second tubular wall extending forwardly from said first tubular wall, a neck portion connected to a front end of said second tubular wall, and an annular flange protruding outwardly and radially from a front end of said neck portion, said tubular main body further having a plurality of angularly spaced-apart protruding ribs extending from an inner wall surface of said first tubular wall to an inner wall surface of said second tubular wall, said second tubular wall having a frusto-conical shape and tapering from a rear side to a front side of said second tubular wall; and a spindle inserted into said tubular member and rotatable about the axis, said spindle including a guide entry section disposed rearwardly of said first tubular wall, a crushing section extending forwardly from said guide entry section into said first tubular wall, a grinding section extending forwardly from said crushing section into said second tubular wall, an extension section extending forwardly from said grinding section into said neck portion, a guide exit section extending forwardly from said extension section into said annular flange, a guide thread helically wound around said guide entry section, a crushing thread connected to said guide thread and helically wound around said crushing section, and a plurality of spaced-apart grinding threads helically extending from said grinding section to said guide exit section, said guide thread having a first ring segment helically extending one revolution around said guide entry section, and a second ring segment connected to one end of said first ring segment and helically extending one revolution around said guide entry section, said first ring segment having a thread depth smaller than that of said second ring segment. |
