Drying Cart

For drying large amounts of cannabis buds we use a Drying Cart whether in existing or new drying rooms.

The main difference between the traditional drying racks that cannabis growers currently use and our drying racks is that in traditional methods the air blows over the product, while, on the other hand, in our innovative method the air is sucked from top to bottom throughout the whole product. As a result, each and every cannabis bud is evenly dried and the quality of the final product is significantly improved.

You can use drying racks for medical and recreational cannabis as well. 

To clarify, you can place a maximum of three sandwich units in one rack.  

Per one drying cycle, in the properly filled rack, you can dry 25kg(55lbs) of cannabis buds at the same time. And one drying room can certainly be filled up with a lot (like a dozen) of it.

How do we fill the Drying Cart?

  • Firstly, at the top of the piles of Canna-trays, there are 3 filters.
  • Secondly, 6 piles of Canna-trays you can place on these 3 filters in the rack.
  • Finally, at the bottom of the rack, as well as at the top, there are 3 filters.

Details of how the Drying Cart works:

  • There are 4 ventilators (D) that suck the process air (1) through a specific row of racks above them.
  • Therefore that process air (1) goes through the HEPA filter and filer pad (B&C) and through the Canna-trays (A) full of cannabis.
  • While going through cannabis, process air absorbs moisture from it.
  • A part of the wet process air (2) goes towards the drying unit (F), through the tubes (E).
  • In the drying unit (F) moisture is then absorbed from the air and the temperature of the air is going up.
  • This dried and warm air (3) mixes with the process air (4) that already circulates.
  • Finally, the mixed air is at the wanted humidity and temperature again and enters the racks (1).

The Drying Carts standing in a row:

The Carts in the middle

Standing in the middle of a row, all racks have both, the slide (at the bottom) and the valve (on top) open.


The Cart at the back

Standing at the end of the row, the rack has the valve closed and the slide open.


The Cart at the front

Standing at the beginning of the row, the rack has the valve open and the slide closed.


ABC-processor for the drying racks:

  • You can control the quantity of the airflow for each and every rack individually; if there is more humidity then you need more airflow.
  • There are two sensors for measuring temperature and relative humidity, and in this case, the first measures the ingoing, and the second measures the outgoing air.


Note: racks for cannabis drying are designed so that they can be used in new drying rooms as well as in existing ones. Most importantly, it is possible to implement the ABC-processor in an existing drying room.
