Project Overview
On October 26, 2026, Western Flag successfully completed the delivery of two 30 HP air-source heat pump drying rooms for a shiitake mushroom processing project in Qujing, Yunnan, China.
The equipment is designed to support local mushroom drying operations, helping the customer establish a more consistent and efficient drying process.
Drying shiitake mushrooms requires more than moisture removal. Appropriate temperature and humidity control at different stages is important for maintaining product appearance, natural color, aroma, and overall quality. Air-source heat pump drying technology offers a clean and energy-efficient approach to mushroom processing, with the added benefit of programmable process control.
Key Advantages of Air-Source Heat Pump Drying
1. Precise Temperature Control for Consistent Drying
Shiitake mushrooms require different drying conditions at different stages of the process. With a properly designed drying program, operating parameters can be adjusted according to the processing requirements, helping achieve more consistent drying results while reducing the risk of discoloration, cracking, or localized overdrying.
2. Energy Efficiency and Lower Operating Costs
Air-source heat pumps extract thermal energy from the surrounding air and use it to provide heat for the drying process. Compared with direct electric heating, heat pump technology can reduce energy consumption under suitable operating conditions, helping processors manage long-term operating costs. Actual energy savings depend on ambient conditions, equipment configuration, drying procedures, and operating practices.
3. Cleaner Processing with Reduced Smoke Exposure
Air-source heat pump drying rooms use heated air rather than direct combustion as the drying heat source. When operated without coal-fired or other direct-combustion heating, they can reduce smoke and combustion-related pollutants around the drying process, helping minimize unwanted smoky odors on the finished mushrooms.
4. Intelligent Control for Easier Operation
With a PLC-based control system, operators can manage equipment operation and relevant process parameters according to preset drying programs. This helps reduce the need for frequent manual intervention and makes daily operation more convenient. Specific automation functions depend on the actual project configuration.
5. Reliable Production with Less Dependence on Weather
Unlike traditional sun drying, indoor drying rooms allow mushroom drying to take place under controlled operating conditions. This reduces dependence on sunlight and helps minimize disruptions caused by rainy weather or seasonal changes, supporting more predictable production planning.
6. A More Energy-Conscious Drying Solution
By utilizing heat from the surrounding air, heat pump technology offers an energy-efficient alternative for suitable drying applications. Combined with appropriate equipment selection and process management, it can help food processors improve energy utilization and support more sustainable production practices.
