Medical Hemp: Gentle Drying of Cannabis Buds

Harter Logo

Trolley Dryer für Medical Hemp / Cannabis Buds

Many countries have adopted statutory regulations allowing the cultivation and processing of cannabis for medical purposes. Others are about to follow suit and make the necessary preparations. We are already prepared!

Those who want to subject cannabis buds to extraction or want to condition cannabis buds to preserve and transport them will find themselves confronted with the drying issue. Cannabis buds must be dried in a gentle, reliable and, of course, uniform manner. Our way of drying fulfils all these requirements – and in an efficient manner on top of it!

> gentle through low processing temperatures
> reliable through drying in a closed system
> uniform through an evenly directed airflow
> efficient through heat pump technology

In co-operation with one of the leading cannabis specialists we have developed a trolley dryer perfectly suited to dry the sensitive buds. Some of these dryers are already in operation.

Other Advantages

_ Higher product quality in terms of bioactivity, aroma and ingredients through closed system
_ Condensate may be collected.
_ High process confidence through controllable and constant process parameters
_ Higher throughput may be obtained easily. The system may be enlarged every direction.

The trolley dryer may also be a building block of a process in conformance with GMP requirements.
