Pollinator P500 Bottomless Tumbler – Automatic 500g Dry Sifting Machine

The Pollinator P500 Bottomless Tumbler is a high-capacity automatic dry-sifting machine designed for efficient botanical screening, pollen separation and fine particle collection. Featuring a 500g batch capacity, an electric rotating mesh drum and an innovative bottomless collection system, this machine offers a convenient solution for processing suitable dried botanical materials.

Unlike a standard enclosed tumbler, the P500 Bottomless features an open-bottom collection arrangement that allows screened particles to fall directly into removable trays beneath the machine. This makes it easier to collect material at different stages without repeatedly removing the screening drum.

Supplied with a 150-micron screening drum and two food-grade collection trays, the P500 Bottomless combines automatic operation with convenient material handling. Additional Pollinator Extra Drums are available separately for users who require alternative screening sizes.

• Cold-environment compatibility: Designed for suitable temperature-controlled processing environments.
• Easy maintenance: Removable collection trays and screening components simplify routine cleaning.

What Makes the P500 Bottomless Different?

The main advantage of the Pollinator P500 Bottomless Tumbler is its combination of increased processing capacity and an accessible collection system.

The bottomless configuration allows fine screened particles to fall into collection trays positioned beneath the rotating drum. This enables material to be collected between screening rounds without repeatedly dismantling the barrel.

The two supplied trays are particularly useful when separating material collected at different stages of processing.

Benefits of the Bottomless Collection System

• Convenient access to collected botanical particles
• Reduced need to remove the screening barrel
• Two removable collection trays supplied
• Separate collection of different screening rounds
• Practical for repeatable botanical processing sessions
• Compatible with additional collection trays where available

Automatic Dry Sifting for Botanical Materials

The Pollinator P500 Bottomless Dry Sifting Machine uses a motor-driven cylindrical mesh drum to separate fine particles from larger dried plant material.

As the barrel rotates, suitable botanical material moves within the mesh drum. Smaller particles pass through the screen, while larger material remains inside the barrel.

The separated particles fall into the collection tray beneath the machine, providing a convenient method of collecting screened material.

This automatic mechanical process offers a practical alternative to manually shaking dried material through a stationary sieve.

500g Batch Capacity for Larger Processing Requirements

With an approximate capacity of 500g of dried botanical material per batch, the P500 Bottomless provides more than three times the nominal batch capacity of the smaller P150 Bottomless model.

This makes it suitable for users who require greater processing volume while retaining the convenience of a compact automatic screening system.

Actual working capacity may vary depending on the density, condition and characteristics of the material being screened.

Includes Two Removable Collection Trays

The Pollinator P500 Bottomless includes two removable food-grade collection trays designed to sit beneath the rotating screening drum.

These trays make it easier to gather screened particles and organise material from different collection rounds.

Additional compatible stackable trays may be used to expand the collection arrangement, where available.

Please Note: Additional collection trays are sold separately and are not included with the standard machine.

150-Micron Screening Drum Included

The Pollinator P500 Bottomless is supplied with a standard 150-micron (150µm) screening drum.

The micron rating describes the approximate size of the mesh openings. Particles sufficiently small to pass through the screen are separated from larger material retained inside the barrel.

The supplied drum provides a practical starting point for a variety of compatible dry botanical screening applications.

Compatible Pollinator Extra Drums – Available Separately

The Pollinator P500 Bottomless Tumbler is compatible with interchangeable screening drums, allowing users to select different mesh sizes for their botanical processing requirements.

Our Pollinator Extra Drum Range includes compatible replacement and additional barrels for the P500 model.

Available Micron Sizes

• 70 Micron: Fine particle screening.
• 90 Micron: Fine mesh separation.
• 120 Micron: Intermediate fine screening.
• 150 Micron: Standard screen size supplied with the machine.
• 185 Micron: Coarser particle screening.
• 220 Micron: Larger mesh openings for coarser screening.

Finer screens have smaller openings, while coarser screens allow larger particles to pass through.

Important: When ordering, select the P500 model and your preferred micron rating.
