• Processes Up to 108 lbs Dry Per Hour
• Variable Speed Control with Integrated Timer
• Adjustable Industrial Stand for Mobile Positioning
• 3-Year Manufacturer Warranty

Unlike trimming systems that rely on aggressive suction or high-impact cutting, the DBT Model 4 gently rotates dried material inside a large electropolished stainless steel tumbler. This controlled movement encourages unwanted leaf matter to pass through the plastic blade sheet while helping preserve the natural structure and appearance of the finished material.

The integrated Variable Speed Control allows the tumbler rate to be adjusted according to material size, density, moisture level, and desired finish. Lower speeds provide gentler handling for delicate batches, while higher settings increase movement and throughput for denser material.

An automatic timer allows operators to establish repeatable cycle lengths and stop the machine at the end of each programmed run. Once the ideal settings have been identified, teams can reproduce the same process across future batches while reducing the risk of over-processing.

The DBT Model 4 includes an adjustable industrial stand with locking casters. This mobile platform improves loading, unloading, cleaning, and facility positioning while allowing the machine to be moved between processing areas as production requirements change.

Its oversized tumbler measures approximately 66 inches long and 20 inches in diameter, providing the capacity required for high-volume dry processing. The machine measures 67 inches long, 36 inches wide, and 53 inches high, creating a substantial but efficient footprint for commercial facilities.

The anodized aluminum frame and electropolished stainless steel tumbler are engineered for repeated industrial use. A 1/4 HP motor provides dependable movement while drawing only approximately 3 amps from a standard North American 110V supply.

A removable trim collection system captures separated plant material beneath the tumbler, helping keep the surrounding workspace organized and simplifying recovery after each batch.

The DBT Model 4 is also compatible with an optional Sorter Conversion Kit. This accessory transforms the trimmer into a high-capacity size sorter in less than five minutes and can sort up to approximately 125 pounds of material per hour.

Backed by a 3-year manufacturer warranty, the CenturionPro DBT Model 4 is built for commercial operators who need industrial dry-processing capacity, adjustable control, automated timing, mobile positioning, and dependable batch-to-batch consistency.
