Cannabis Drying Rack

A Cannabis Drying Rack is used to dry large volumes of cannabis buds in an existing or new drying cell.

The main difference with drying racks currently used by cannabis growers is that the process air is sucked top-down through the product by a ventilator. In the traditional method air is blown over the product. Our Top-down drying method results in an evenly dried end-product. 

For medical and recreational cannabis. 

In the drying rack, 3 sandwich units are placed.  

One drying rack is capable of drying 25kg (55lbs) per drying cycle. A drying cell can be filled with dozens of drying racks.

How is the Drying Rack filled?

  • 3 filters are placed at the bottom of the drying rack.
  • 6 piles of Canna-Trays are placed on the filters in the rack.
  • 3 filters are placed on the piles of Canna-Trays.

Drying Rack – Details of how it works:

  • The 4 ventilators (D) suck the process air (1) through a row of drying racks.
  • The process air (1) goes through the filters (B&C) and the Canna-Trays (A) where it dries the cannabis by adsorbing moisture.
  • A part of the wet process air (2) goes through the tubes (E), towards the drying unit (F).
  • In the drying unit (F) water is adsorbed from the air and the temperature of the air rises.
  • This warm and dried air (3) mixes with the circulating process air (4).
  • The mixed air is at the desired temperature and humidity again and enters the drying racks (1).

How are the Drying Racks placed in a row:

Racks in the middle

The racks placed in the middle of a row of racks all have the slide (below) and the valve (on top) open.

M

Back

The rack at the end of the row has the valve closed and the slide opened.

B

Front

The rack at the beginning of the row has the valve opened and the slide closed.

F

ABC-processor for the drying racks:

  • The amount of airflow can be controlled for each drying rack individually; more moisture means more airflow.
  • Two sensors to measure temperature and relative humidity. The first sensor measures the ingoing air from the cell, the second sensor measures the outgoing air.

 

Note: Drying racks can be used in existing and new drying cells. The ABC-processor can be implemented in an existing drying cell.
