ABSTRACT:
A system and corresponding process for cleaning sugarbeet pulp comprising: (a) a tank wherein a sufficient amount of water is added to the pulp to form a first slurry containing about 0.1 to 4 wt-% pulp; (b) a screening apparatus for separating the first slurry into a top portion containing substantially all of the pulp and a bottom portion containing a major proportion of the free foreign material; (c) a mill for reducing the particle size and loosening of adherent foreign material from the pulp; (d) a tank for adding a sufficient amount of water to the top portion to form a second slurry containing about 0.1 to 4 wt-% pulp; (e) a screening apparatus for separating the second slurry into a upper portion containing substantially all of the pulp and a minor proportion of the loosened foreign material and a lower portion containing a major proportion of the loosened foreign material; (f) a tank for adding a sufficient amount of water to the upper portion to form a third slurry containing about 0.1 to 4 wt-% pulp; (g) a screening apparatus for separating the third slurry into a overflow portion containing substantially all of the pulp and an underflow portion containing a major proportion of the minor proportion of loosened foreign material; and (h) a pulp press and thermal dryer for removing water from the sugarbeet pulp to form a dried product having less than about 11 wt-% water.
This system may optionally include a hydrocyclone for removing foreign material from the bottom and lower portions so as to form recyclable water.
