Pollinator P500 Pollen Tumbler Dry Sifter

For maximum kief yield, freeze your plant material before loading the drum and run the machine in the coldest environment possible — ideally inside or next to a top-loading freezer. Adding dry ice directly to the drum during the sifting cycle keeps temperatures low and helps trichomes separate more cleanly from the plant material.

Stop the machine when the plant material inside the drum turns green — this indicates that most available trichomes have been separated and continued tumbling will pull chlorophyll and plant matter into your product. At that point, remove the drum and collect your dry sift.

Yes — the Pollinator P500 is specifically designed to fit inside a standard top-loading freezer. Running the machine at sub-zero temperatures produces the best dry sift results by keeping trichomes brittle and easy to separate from the plant material.

The P500 comes equipped with a 150-micron screen drum, which is the standard size for dry sifting kief and pollen from cannabis plant material. The 150-micron mesh passes trichome heads while retaining the bulk of plant matter inside the drum.

Yes — the P500 is fully dry-ice safe. Adding dry ice to the drum is actually the recommended method for maximizing extraction efficiency. Always handle dry ice with insulated gloves and ensure adequate ventilation in your work area when using it.

The P500's 500-gram capacity makes it the step-up choice for medium to large-scale operations that have outgrown smaller entry-level tumblers. The motorized drum and food-grade construction are shared across the lineup, but the P500 processes significantly more material per run with the same ease of operation.

Remove the drum after each session and brush or tap out any remaining plant material. The food-grade components and 150-micron screen can be cleaned with a soft brush — avoid liquids on the screen mesh to prevent stretching or damage. Allow all components to dry fully before reassembly.
