Selection of Constant Temperature Refrigeration Equipment for Traditional Chinese Medicine Storage, Key Points of Temperature and Humidity Control Specialized Units

The storage of medicinal herbs demands stringent temperature and humidity control standards, as imbalances can lead to pest infestation, mold growth, and loss of active ingredients, significantly reducing the economic value of the herbs. General fresh produce cold storage units lack precise humidity regulation capabilities and cannot meet the long-term constant-temperature storage requirements of medicinal herbs. This article outlines the key considerations for selecting specialized refrigeration equipment for herbal warehouses.
1. Exclusive Temperature and Humidity Control Requirements for Traditional Chinese Medicine Warehousing
Most root and rhizome medicinal herbs, as well as those with ornamental leaves, should be stored at a suitable temperature of 0°C to 15°C, with relative humidity maintained between 45% and 65%. High humidity environments promote mold growth, while excessively low humidity causes dehydration, cracking, and loss of efficacy in the herbs. The equipment must be equipped with an independent dehumidification module to precisely regulate warehouse humidity based on the specific herb categories, differing from the basic temperature-only control function of conventional cold storage.
Medicine warehouses are often built outdoors in towns and industrial parks, where significant day-night temperature variations and consistently high air humidity necessitate equipment with superior corrosion and rust resistance compared to conventional indoor cold storage units.
II. Optimal Configuration of Cold Air Blowers and Condensing Units in the Herbal Medicine Warehouse
The air cooler is designed with a large fin spacing model to minimize the accumulation of herbal dust and prevent duct blockage, facilitating regular blowing and cleaning. The entire machine casing and heat exchanger feature dual-layer anti-corrosion coating to resist corrosion from high-humidity outdoor air. The electrical control system is equipped with a high-precision dual temperature and humidity control system, which records warehouse data in real time to meet the traceability management requirements for herbal storage.
The bulk medicinal material storage warehouse has a large area and employs multiple small air coolers for distributed air supply, preventing excessive temperature and humidity differences in warehouse corners to ensure a uniform and balanced storage environment for medicinal materials.
III. Category-Specific Herbal Medicine Equipment Solutions
Storable root and stem herbs: Standard constant temperature and humidity control unit with basic anti-corrosion configuration;  Flowers and fruit peel herbs prone to mold: Upgraded high-capacity dehumidification module to reduce operation time during high humidity weather;  Rare and precious herbs: High-precision variable frequency unit with temperature control fluctuations within ±0.5°C, paired with an independent zoned refrigeration storage system.
IV. Service Advantages of Source Factory Adaptation for Agricultural Herbal Medicine Storage
Shaoxing Xueying Refrigeration specializes in developing dedicated refrigeration systems for constant-temperature storage of medicinal herbs and fruit/vegetable cultivation. The equipment can adjust unit power, dehumidification modules, and corrosion resistance levels based on warehouse size, local climate, and herbal categories. It supports small-batch single-unit procurement and complete warehouse system exports. With simplified operation panels tailored for farmers and herbal processing plant staff, it comes with a graphical and text-based temperature/humidity regulation operation manual, ensuring adaptability for herbal storage projects worldwide.
V. Daily Moisture Prevention and Maintenance Recommendations for Herbal Medicine Warehouses
Install insulated buffer doors at warehouse entrances and exits to reduce the inflow of humid external air; regularly clean herbal dust from the surface of air coolers to ensure unobstructed airflow; activate the dehumidification mode of the unit in advance during the rainy season to stabilize the warehouse humidity range; conduct annual maintenance on the anti-corrosion coatings of equipment to delay the rusting and aging of pipelines and casings.
summary
The core requirement for constant-temperature storage of traditional Chinese medicinal materials is precise synchronous control of temperature and humidity. Standard refrigeration units for general cold storage cannot meet the standards for mold and insect prevention. Selecting specialized refrigeration equipment with dehumidification functions and optimized anti-corrosion structures, combined with standardized warehouse moisture management, can ensure long-term preservation quality of medicinal materials and reduce mold-related losses.
