A More Efficient Way to Process & Package Produce

The Challenge:

The client needed to be able to sort up to 6000 lbs. of produce an hour, grade that produce,
and then package it in a variety of ways including loose product, cased product, and
bagged product. Prior to the Wrabacon system, the grading portion of the operation was
done by opening a box of produce and hand picking the good from the bad and transferring
the bad product into a separate box which was then disposed of, which was time
consuming and inefficient.

The Solution:

• An automated conveyor system to improve overall efficiency
• An inclined feed conveyor that is manually loaded
• A grading conveyor that allows operators to physically sort different grades of
produce quickly and easily
• A waste conveyor to remove unwanted produce efficiently
• A portable conveyor used for bagging produce that can be easily added when
needed
• Easy controls to allow certain parts of the system to be halted as product is moved
by hand without interrupting the overall process

Produce Handling System Operation
After manually loading the produce onto the conveyor, operators stand along the conveyor
and grade the produce as it passes by. The grading conveyor consists of ¾” diameter
rollers that rotate the produce as it passes by. Unwanted produce is placed onto the waste
conveyor that travels in the opposite direction. The good product is transferred into a
hopper that brings the produce up to the top of a small hopper. From the hopper, the
product is handled one of two ways; into a bulk case or directly onto a takeaway conveyor
for individual packaging.
For packaging, the boxes or bags (the portable bagging conveyor can be easily moved onto
place when needed) are placed on a scale and filled to the required weight. When that
weight is reached, the conveyor feeding produce can be easily stopped via a button so the
operator can move the box or bag off the scale. However, the grading conveyor is still filling
the hopper, so the overall process does not get delayed. When the operator is ready to
continue, a simple press of the button starts the process again.
Once the product is packaged, it is set along another conveyor that allows the containers
to be clipped or tied and easily labeled.
