The drainage water tray. under the
perforated plates, may be divided into
compartments to Permit recycling of only
a portion of the water with the balance
going to sewer. The discharge
consistency from the unit is about 15%.
Another self—cleaning unit which also
permits washing of the dewatered bagasse
is the "Circular Dewatering Table“ [see
Fig. 4). This is a patented design
invested by J. Badiuk. The circular
Dewatering Table is an annular tub with a
perforated stainless plate drainage
surface on the bottom. on which the
slurry of bagasse fiber is dewatered.
The slurry enters the tub from a headbox
and is transported over the perforated
plate by a series of paddles fitted with
rubber or neoprene scrapers connected to
drive arms projecting from a vertical
drive shaft. The drained water is
collected under the perforated plate and
returned to the process. During the
transport of the slurry. it can be
dewatered and then washed a number of
times if desired. The dewatered fiber.
at a consistency of about 15%. then drops
to a discharge chute located at about 320
degrees from the point of entry that
passes through the perforated plate and
the bottom of the tub.
