Filling The Hopper - Conair TrueFeed User Manual

7.8 Filling the hopper

MANUAL FILLING
The controller automatically detects when the hopper is manually filled. During the time that the hopper is
being filled, the TrueFeed is feeding with a fixed RPM, this means the unit runs temporarily volumetric. As soon
as the hopper filling is complete, the TrueFeed immediately resumes working gravimetric.
AUTOMATIC FILLING (optional)
Introduction
Conair Truefeed feeders are capable of handling a variety of pelletized materials. Two different filling systems
are available depending on the material properties.
The Conair Ejector (ME) system is for dust-free or nearly dust-free materials.
The Conair Vacuum (MV) system is for materials that are NOT entirely dust free.
The ME and MV systems are both driven by low-pressure compressed air and mounted directly on top of the
hopper lid of the TrueFeed. The TrueFeed controls the operation of the ME or MV systems.
All parts are aluminum or stainless steel and are virtually maintenance-free. Only the filter needs to be cleaned
periodically. To increase reliability and safety, there are no moving parts except for the pneumatically-operated
closing valve of the MV system.
How the ME works
The ME system blows the material from a bag, drum or container into
the feeder's hopper. The hopper lid of the housing has a simple and
easy-to-clean dust filter to keep any dust particles in the
The system is triggered by the filling start weight (CONFIGURATION menu).
This parameter also generates a low-level alarm if the hopper is empty.
How the MV works
The MV system uses a 3-stage vacuum generator driven by compressed air
to create a vacuum that draws material into a chamber that closes. Once the
chamber is filled with material, the cone that closes the chamber will open
and the material will be discharged into the hopper.
The system is equipped with a superior filter to ensure that the finest
particles (> 5 micron) stay in the system and are not released into the
atmosphere. This makes the MV system the most practical and user-friendly
system for both free-flowing powders and granules.
