DRY TRIMMING OPERATING PROCEDURE
1. Install dry barrels
2. Use Zoom 100micron dry bags top & bottom or plastic vacuum
bags on bottom of vacuum for reduced airflow.
3. Dry tumbling is 70% tumbling action and 30% cutting action
Material condition & processing procedure
Material conditions are critical for successful dry tumbling results. Anything outside of the idea dryness conditions will result with less than perfect results and possible loss of material.
The material needs to be crispy on the outside and have higher moisture content on the inside to keep the flowers from breaking up.
Outer leafs need to crumble when touched before starting. If leafs bend the dry trimming process will not work and requires more drying. With flash drying you have a limited window of time to process as the material will reconstitute itself and become rehydrated on the outside over time.
Medium to large stems need to be previously trimmed before the dry tumbling operation. Stems can be extremely hard and may cause damage to barrel if not properly trimmed.
Idea shape is round or semi round flowers for best results as material gets tumbled.
Keep the material volume in the barrels as uniform as possible with the proper flow rate. Too much volume will stop the tumbling action and to little will reduce efficiency and final results, usually about ½ full.
You may need to increase the barrel angle (machine tilt angle) to overcome the vacuum force for proper material flow.
