Erase Recipe or Entire Book
The Erase Recipe or Entire Book function is used to eliminate old or outdated recipes from the
recipe book. If the operator only wants to delete one recipe, the configuration for that recipe should
be currently displayed on the screen. The controller will only prompt the operator if they want to
erase the entire book when that key is pressed. Once a recipe number is deleted, the contents of that
recipe are lost. The recipe number may be used again in the future for new recipes.
Color Changes
The color change procedure is meant for use with the basic Slide Gate/Auger Blender. This
procedure assumes that the color component of the blend is in an additive ingredient hopper (#2, #4,
#5, or #6).
1. Disable and clean any color loading equipment. Please refer to the loading equipment
manual for any clean up recommendations.
2. Using the blender “Abort” or “Push to Start or Stop” key put the blender in stop mode. After
the cycle has completed, switch “OFF” the main power switch and unplug the blender power
supply.
3. Open the upper mixer access door. This shuts off air to the blender circuit by deactivating
the master air valve. Then unplug the quick disconnect from the air supply hose to the
blender to further ensure that no air pressure is supplied to the blender.
WARNING! Always unplug the main power cord and disconnect the air supply to the blender
prior to performing any operations inside any access areas of the blender where
there are moving parts.
4. Remove the weigh hopper by unplugging the air line disconnect fitting, holding the dump
door closed, lifting the hopper to clear the load cell brackets, and gently pulling the weigh
hopper out of the blender.
Caution! To reduce the chance for damage to delicate load cells, use care when lifting the
weigh hopper off load cell locating tabs and when reinstalling the weigh hopper
on load cell brackets.
5. If you want to catch the color, use a small plastic pail or chute to collect the material from
the slide gate assembly. Reach up inside the blender to the color slide gate and push it open.
At this point, there should be no air pressure on the blender, and the slide gate should move
easily. Drain the color out in the bucket. Blend and Reclaim normally provides a JIT (Just in
time) approach to the minor ingredients, so that a minimum amount of material is held in the
blender so that color changes can be made easily.
6. If any other ingredients need to be changed for the next recipe, simply drain the larger
hoppers with the drain tubes provided on the side of the hoppers. When the material level is
below the drain tube, open the slide gate manually to dump the rest of the material. If you
wish to speed the emptying process, material can be manually drained out of the slide gate
assembly into a dump chute or bucket, while draining from the drain tube.
Note: The blender must be stopped to make color changes. The processing machine
can operate on virgin material only during this procedure with an optional
quick color change bypass tube that can be installed to bypass the blender.
