Noodle string treatment apparatus and treatment method

A noodle string treatment method, comprising steps of:

• conveying a batch of noodle strings;
• cutting the batch of noodle strings at a constant cutting time interval by using a rotary blade that has a flat shape, is attached to a rotating shaft and extends out from the rotating shaft;
• and
• extruding the cut batch of noodle strings by the rotary blade, wherein:
• a blade edge of the rotary blade extends along a direction in which the rotating shaft extends,
• the rotary blade cuts the batch of noodle strings at a cutting point, which is a point where the blade edge of the rotary blade is closest to or comes into contact with an outer circumferential surface of an oppositely disposed roller,
• in the step of cutting the batch of noodle strings, a blade edge peripheral speed of the rotary blade is changed during rotation thereof between a cut and a next cut,
• in the step of cutting the batch of noodle strings, the batch of the noodle strings is cut at a position where a lengthwise direction of the batch of noodle strings extends in a vertical manner,
• the rotary blades comprises a plurality of rotary blades attached to the rotating shaft,
• in the step of cutting the batch of noodle strings, the blade edge peripheral speed of the plurality of rotary blades is changed periodically with a constant time interval over a plurality of cycles, wherein each of the plurality of cycles is a time period from one cutting timing by one of the plurality of rotary blades to a next cutting timing by another of the plurality of rotary blades cutting the batch of the noodle strings subsequent to the one of the plurality of rotary blades, and
• the blade edge peripheral speed when one rotary blade among the plurality of rotary blades extrudes the cut batch of noodle strings after the one rotary blade cuts the batch of noodle strings is set to be lower than the blade edge peripheral speed of the rotary blade when the one rotary blade cuts the batch of noodle strings.
