4.3 Feeding-out
During mixing, the mixing chamber is separated from the feed-out chamber by a variable feed
control (VFC) door, thus ensuring complete mixing. The feed-out chamber contains an auger,
which runs the entire length of the machine.
When chopping/mixing is complete, the feed-out tray should be set to the required position and
the VFC-door dropped, allowing the material to be swept up by the paddles and pushed onto
the auger (see Figure 2). At first, the VFC-door should only be partially opened (not more than
halfway). When feed is seen discharging, allow 15
–20 seconds to pass before fully opening
the VFC-door. Door position and ground speed should be set and used to allow for an even
feed-out rate.
CAUTION:
The VFC-door should only be opened or closed when the PTO is engaged
(with
paddles turning) when material is in the machine.
4.4 Maintenance
Figure 1: KEENAN MechFiber400
A properly operated and maintained KEENAN diet feeder promises to operate trouble-free for
years.
Regular maintenance of the machine is essential both for long machine life and
also to meet the warranty requirements
. Refer to instructions in the maintenance section of
this manual. Weekly cleaning of the machine is recommended to prevent corrosion to the mixer
body from old feed.
The level of cleaning required will depend on the material being
mixed, but any material that sits or lodges on the machine may adversely affect both the
operation of the machine and the quality of the mix, if it subsequently falls into the
feeder during mixing. It is therefore essential to routinely clean and wash down the
feeder.
