1. The close-coupled waste handling system is designed to reduce the volume of waste created in the food
service operation thereby reducing the expense associated with conventional methods of waste removal
and disposal. The waste handling system accomplishes this by combining food, paper and water,
removing the water and then compressing the waste for disposal.
2. The waste handling system consists of a grinding tank, (pulper), and a water press, (water extractor).
The 2 components are physically connected (close-coupled) and share a common electrical control
system.
3. The pulper contains a spinning grinding disk and cutting blocks which shred food waste and paper
to a water-laden mixture called slurry. The pulper forces the slurry into the water extractor.
4. The water extractor contains an auger and screen. The auger rotates inside the circular screen
moving the slurry upward to the top of the water extractor. Water is gradually removed from the
slurry by the action of the auger and screen.
5.
A compression cone, located at the top of the water extractor is the final stage in the water
extraction process. The cone compresses the waste into a semi-dry, papery pulp
and then pushes it out of the water extractor and into waste containers for disposal.
6.
The pulper is filled with fresh water initially. After that, the water-level in the pulper and the water
extractor is maintained by the combination of recirculated slurry water and fresh make-up water.
Slurry moves from the pulper into the extractor, water is removed from the slurry and then returned
to the pulper via cross-flow piping or via an optional recirculating pump and waste trough system.
The cross-flow piping is blocked when the optional recirculating pump is used. A drain/overflow
skims excess water from the water extractor during normal operation and is used to drain the system
during the clean-up operation.
7.
There are 2 methods for feeding waste into the pulper. In the first method, the operator manually
feeds the waste directly into the pulper. In the second method, waste is conveyed into the pulper
via a water-fed trough system.
8.
The standard electrical controls consist of a common remote-mounted control box , 1 Start/Stop
push-button station on the pulper and 1 push-button station on the water extractor. The pulper water-
level is controlled by a pressure switch mounted on the side of the pulper. Safety switches mounted on
the pulper and the water extractor protect the operator from rotating components. An optional deodorizer
injector can be mounted on the water extractor.
9. The waste handling system must be cleaned
daily after the day's operation. Optional flushing
systems in the pulper and the water extractor
aid in removing solids that may be present.
Foreign matter must be removed manually and
the machine interiors must be flushed with fresh
water. The machine exteriors must be cleaned
as well as the surrounding work areas to prevent
odors and reduce the accumulation of debris.
Theory of Operation
Theory of Operation
Refer to the illustration on the preceding page as you read the theory of operation below.
The close-coupled waste handling system is made up of 2 units: a pulper and a water extractor.
Waste is compressed into a semi-dry, papery pulp.
