    • A granular absorbent and granular absorbent making method producing granular absorbent from a carbohydrate starch-containing cereal grain, e.g., corn, based admixture extruded from a single screw or twin screw extruder forming liquid absorbing pellets having a clumping agent formed during extrusion composed at least in part of carbohydrate polymer binder. Each pellet is extruded under conditions that cause formation of carbohydrate polymer binder clumping agent at least some of which is water soluble. One preferred method of extruding granular absorbent causes starch dextrinization to occur such that at least some of the carbohydrate polymer binder clumping agent in each liquid absorbing pellet of the granular absorbent is formed of dextrin. Each pellet can be coated such as with a smectite that preferably is bentonite. During use, clumping agent formed during extrusion of a pellet dissolves and flows in between and along adjacent pellets when the pellet(s) is/are wetted causes the pellets to "self-clump" without the presence of any clumping agent additive producing a granular absorbent that not only performs well but which is faster and easier to clean up as a resulf of its "self-clumping" formulation.
    • 一种粒状吸收和粒状吸收制造方法,其由含有碳水化合物淀粉的谷物颗粒(例如,从单螺杆或双螺杆挤出机挤出形成的液体吸收颗粒)挤出形成颗粒状吸收剂,其中所述颗粒吸收颗粒具有在挤出过程中形成的聚集剂,至少在 部分碳水化合物聚合物粘合剂。 每个颗粒在导致形成碳水化合物聚合物粘合剂结块剂的条件下挤出,其中至少一些是水溶性的。 挤出粒状吸收剂的一种优选方法导致淀粉糊精发生,使得粒状吸收剂的每个吸液颗粒中的至少一些碳水化合物聚合物粘合剂团聚剂由糊精形成。 每个颗粒可以涂覆,例如优选膨润土的蒙皂石。 在使用过程中,颗粒挤出过程中形成的聚集剂在颗粒被润湿时溶解并流入相邻颗粒之间并流过,导致颗粒“自团结”,而不存在产生颗粒状的任何聚集剂添加剂 吸收剂不仅表现良好,而且更快更容易被清理,作为其“自我凝聚”制剂的一部分。
