Gravimetric Batch Blenders w/Mitsubishi Control Chapter 3: Installation 38
The Recipe Format screen allows the user to change many parameters concerning the way
that the recipe is entered by the operator. It is accessed by touching the manufacturer’s icon
on either the Recipe screen or the Inventory Screen. The user must enter in the User
Password to gain access (see User Password Setup for details.). The following Recipe
Modes are described on the next page:
“Quickset” Mode (Most common in injection molding)
The “Quickset” menu structure allows recipes to be entered and adjusted by touching the
buttons on the panel face (for 1 to 6 components). In this mode, hopper #1 is configured as
virgin, hopper #3 is configured as regrind, and the others are configured as additives, i.e.
color. The operator enters in the percentage of regrind and additives, and the virgin
percentage is automatically calculated. The regrind percentage represents a percentage of the
total batch, and the additives are based on a percentage of the virgin weight. This is useful
because the percentage of regrind can be changed without affecting the ratio of color or
additive to the virgin weight. Each percentage can be up to 100%, but not greater. The virgin
percentage is automatically calculated by the blender and the operator is not required to enter
it.
The ingredient names selected will be displayed on the run mode display so the operator will
know what material is being blended.
Note:
The #1 hopper (“NAT” - Virgin Material) recipe ingredient will not be shown
on the recipe setup menu.
Note: ADD (Additive) designations will weigh the ingredient as a percentage of
natural material only.
Note: RGD (Regrind) designations will weigh the ingredient as a percentage of the
total batch. (It is assumed the regrind has been generated from pre-blended
production and already contains the same color and/or additives.)
Note: Virgin material must be loaded into hopper #1 and regrind into hopper #3.
Note: Component #3 is designed to handle regrind and most models come equipped
with a larger, square gate to reduce the likelihood of bridging. If regrind is
being used, it should always be run through component #3. If you don’t have
regrind, another major
ingredient can be run through component #3.
Please see Figure 21 on the next page for example calculations (setup).
