Cannabis drying components and materials

Directly after harvesting cannabis is prepared for the drying process: cannabis stems/buds are placed in Canna-trays® (A). Then the operator lays four HEPA H13 filters + Filter Pads (C) on the bottom of a Ventilation-pallet (B). The operator then places the trays on the filters on the Ventilation-pallet (B). Altogether, these components will form a ‘Sandwich-unit’(D)

When the pallet is full (4 piles of x amount of trays) a forklift operator brings the pallet to the drying-cell.






After harvesting the buds are placed in Canna-trays, the central components of the Sandwich units, the buds will stay in the Canna-trays during the drying and curing process.

This component, the Canna-tray is made of ABS (acrylonitrile-butadiene-styrene) Food Safe Thermoplastic, this is the perfect material for your consumable products. ABS thermoplastic is resistant to chemicals like thinned acid, alkaline, oils, fat and aliphatic hydrocarbons.

The Canna-trays are divided into six smaller compartments, this makes sure the cannabis will not slide around and no empty spots will emerge. On the bottom of the Canna-trays, you find little holes, these holes make it possible for air to be sucked through.

The Canna-trays are made of 100% recyclable material.

The Canna-trays are easily stacked on each other with a simple clicking system

Size of the Canna-trays: 600x400x60 mm (23.5×15.5×2.4″)

Maximum service temperature: 77°C (171°F).

A Component called the HEPA-Filters

At the top and bottom of the Sandwich-unit, you will find one more very important component, the High-Efficiency Particulate Air (HEPA) filters. The function of the filters is to filter out fungi and bacteria, this makes sure your cannabis will always pass the microbial test standards.

The HEPA-filters on top of the Sandwich-unit makes sure that all air that enters the cannabis is free from fungi and bacteria. On top of the HEPA-filter, you will find a filter pad for protection.

This component, on the bottom of the Sandwich-unit, catches all the bacteria and fungi that are extracted from the cannabis. On top of this filter lays another filter pad that collects all the kief that is coming free from the cannabis. The filter pads are easily removable, so the kief can be taken elsewhere.

The frame of the filter is made of aluminum while the filter itself is made of high-efficiency micro glass fiber paper. HEPA-filters have the lowest possible air resistance, which helps to lower the energy costs


HEPA-filters are used in multiple cleanroom applications like, operating theaters, the pharmaceutical industry and micro-electronics.

HEPA-filters guarantee constant performances and make sure that the cannabis stays in a clean room environment during all stages of the process.


The component called Ventilation-pallet is made of stainless steel and is assembled in such a way that the whole pallet is easily cleaned.

The front of the pallet has 2 entries, so it can be easily transported by a forklift, no extra actions are required.

The Ventilation-pallets contain 64 to 144 Canna-trays.

Size Ventilation-pallet (without Canna-trays): 1600x 1220x 240 mm (65 x 48 x 9.5 ″) . Weight: 110 kg (240 lbs.)

The Ventilation-pallet is perfect for efficient internal transport. Once the Ventilation-pallets are stacked with canna-trays, all internaltransport can be done by a forklift
