6. Operation
6.1 How it works
The DDC Dolphin Pulpmatic macerator combines water and a rotating blade to smash standard
medical pulp products into a slurry which is easily flushed through an existing drainage system.
A round disc in the base of the chamber is fitted with six blades. As the disc spins at high speed,
the blades smash into the pulp products breaking them down into ever decreasing pieces, each
broken piece becoming more saturated with water. This process is repeated over and over again
throughout the cycle.
The spinning disc separates the upper chamber (this is the loading area visible to the user) and the
lower chamber (this is the section connected to the drain). There is a narrow gap around the disc
and wall of the upper chamber, this narrow gap will only allow items to pass through to the lower
chamber when they have been broken down into very small pieces.
Within this lower chamber, there are three additional chopping blades that reduce the waste into a
fine slurry. An additional injection of water into the lower chamber helps flush and dispose of the
slurry through the machine into the drain network.
Throughout the entire process, a continuous flow of water is provided into the upper chamber, the
lower chamber and the waste pipe leaving the machine. This precise use of water provides the
optimum maceration and flushing of the pulp through the machine into the sewer.
The DDC Dolphin system is constantly draining from the machine into the sewer from the start of
the cycle, the slurry waste is dispersed from the machine as soon as it is small enough to exit
through the gap of the upper chamber, into the lower chamber and down into the drainage system.
This refined and continuous process ensures that blockages do not occur within the unit or the
main drainage system. The two stages, twin chamber maceration process has the added benefit of
operating like a sieve and not allowing any large or foreign objects to pass through the system that
otherwise could leave the chamber and contaminate the drainage system, such as gloves, utensils
and sharps. If it physically cannot pass though the gap between blade and chamber then it will not
enter the drainage system.
