The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A process for production of hydrogel particles, which is a process for production of the hydrogel particles from a high-concentration hydrogel sheet and comprises:
a step (a) of providing a cutting means and cutting a continuous sheet of a crosslinked high-concentration hydrogel polymer of 50 to 80 weight % in solid component concentration every 10 to 100 cm lengthwise of the continuous sheet while running it lengthwise, thereby obtaining cut pieces, said step (a) including a step (a-3) of supplying a medium to the cutting means for cutting the continuous sheet, wherein the medium is selected from the group consisting of water, warm water, and water vapor; and
a step (b) of continuously supplying the cut pieces (obtained from the step (a)) to a continuous disintegrator to continuously carry out disintegration and discharge under conditions where the supply amount of the cut pieces and the disintegrating and discharging abilities of the continuous disintegrator satisfy (supply amount) \u2266 (disintegrating and discharging abilities), thereby obtaining the hydrogel particles.
2. A process according to claim 1 for production of hydrogel particles, wherein, in the step (a), the continuous sheet is cut off lengthwise by meshing between a fixed blade and a rotary blade, wherein the fixed blade is fixed and disposed crossing widthwise on one face side of the continuous sheet, and wherein the rotary blade rotates on the opposite face side of the continuous sheet, around a widthwise crossing axis as a rotational center, and along the running direction of the continuous sheet.
3. A process according to claim 1 for production of hydrogel particles, wherein the step (a) includes: a step (a-1) of cutting the continuous sheet off widthwise into widths of 10 to 100 cm with a rotary blade that rotates within a plane along the running direction of the continuous sheet; and a step (a-2) of cutting the continuous sheet (having been cut off widthwise) off lengthwise to thereby obtain the cut pieces of 10 to 100 cm in widthwise size and 10 to 100 cm in lengthwise size.
