In northern China, winter ambient temperatures regularly drop below -10°C. Jujube (red date) processing requires rapid heating and short processing cycles, but conventional drying rooms suffer from severe energy loss during dehumidification — the exhaust of moist air causes sharp temperature drops inside the chamber, extending drying times and producing inconsistent results.
The AOBOTE Solution
Superior drying room design combined with AOBOTE’s split-type heat pump equipment solves these critical challenges. The system ensures rapid heating and short processing cycles while preventing the energy loss and sharp temperature drops typically caused by moisture exhaust.
This configuration delivers the functionality of an open-closed loop dryer at a significantly lower cost, giving processors a powerful competitive advantage for winter production without the capital investment of a full closed-loop system.
Results
The retrofit enables reliable, year-round jujube processing even in the harshest winter conditions. Rapid temperature recovery after dehumidification cycles keeps the drying process efficient and consistent, while the lower capital cost compared to open-closed loop systems makes the technology accessible to a wider range of processors.
