Abstract
The drying process of hemp flowers is crucial for preserving the quality of cannabinoids, terpenes, aromas, and other valuable compounds. This study investigates the drying of hemp flowers using a condensation dryer, combined with a heat pump. This type of dryer allows for significant energy savings by retaining both the latent and sensible heat within the chamber. Although the drying process is somewhat slower than in conventional dryers, the quality of the drying is exceptional. The dryer operates at slightly lower temperatures, up to 60ºC, making it ideal for delicate products such as hemp flowers, herbs, and chopped fruits and vegetables. The drying process plays a key role in the retention of aroma and in the overall quality of the products. Key drying parameters, including air temperature, humidity, and the amount of condensate collected, are continuously monitored. Results will provide detailed hourly insights into these parameters, along with an analysis of the drying regime, offering recommendations for optimizing the process to preserve product quality.
