In contemporary agricultural production and industrial processing, precise environmental control has become a critical factor in 

enhancing product quality and yield. As equipment capable of accurately regulating environmental temperature and humidity, 

constant temperature and humidity units are increasingly serving as the “invisible guardians” across multiple sectors.

Environmental Guardian for Smart Greenhouses

Traditional greenhouses are significantly affected by external climates, resulting in substantial internal environmental fluctuations. 

The application of constant temperature and humidity machines has completely transformed this situation.

In modern multi-span greenhouses, these machines utilize intelligent sensor systems to monitor environmental parameters in 

real time and automatically regulate the indoor environment. When temperatures exceed preset thresholds, the units automatically 

activate cooling mode; when humidity drops too low, humidification functions immediately engage, ensuring crops consistently 

thrive in optimal growing conditions.

Especially during seedling cultivation, these units maintain stable microclimates, significantly boosting seedling survival rates and 

uniformity. Advanced systems can even automatically adjust parameters based on crop variety and growth stage, delivering precise 

environmental support for crop development.

Precision Environmental Controllers for Mushroom Cultivation

Mushroom crops exhibit extreme sensitivity to environmental fluctuations, making stable yield and quality challenging with 

traditional cultivation methods. The application of constant temperature and humidity machines in mushroom farming achieves 

true “environmental controllability.”

In shiitake mushroom cultivation, these machines precisely maintain the 24°C constant temperature and 65% constant humidity 

required during mycelium cultivation, significantly shortening mycelium germination time and improving bag success rates. During 

the fruiting stage, the equipment swiftly switches to 18°C and 90% humidity to promote primordia formation and fruiting body growth.

For industrial cultivation of mushrooms like enoki and king oyster mushrooms, constant temperature and humidity machines serve 

as core production line equipment. Through layered and zoned environmental control, fungi at different growth stages receive 

optimal conditions, enabling year-round continuous production and significantly boosting facility utilization and production efficiency.

Quality Assurance Experts for Grain Storage

In grain storage, constant temperature and humidity units serve as vital “quality guardians.” Traditional storage methods are 

susceptible to external climatic influences, leading to grain heating, mold growth, or quality deterioration.

Modern grain storage facilities equipped with large-scale constant temperature and humidity units maintain stable temperatures 

below 15°C and humidity levels between 65%-75%. This consistent low-temperature, low-humidity environment effectively 

suppresses pest and microbial activity while slowing grain aging.

Particularly in strategic grain reserve storage, constant temperature and humidity units ensure grains retain superior edible quality 

and nutritional value even after prolonged storage. Some modern grain silos also incorporate intelligent control systems that 

automatically adjust environmental parameters based on grain variety and storage duration, enabling smart management.

Preserving Medicinal Efficacy in Chinese Herbal Drying

The drying process of Chinese medicinal herbs directly impacts the retention of their active ingredients. Traditional methods like 

natural sun-drying or crude drying often fail to ensure consistent quality.

The application of constant temperature and humidity machines in drying Chinese medicinal herbs enables precise control of 

drying temperatures and scientific management of drying rates. For herbs containing volatile oils, the equipment maintains a 

low-temperature environment of 40-45°C for slow drying, effectively preserving medicinal components. For root and rhizome 

herbs, a segmented drying process—low temperature followed by high temperature—ensures thorough evaporation of internal 

moisture without scorching.

In processing valuable herbs like ginseng and astragalus, these units automatically adjust drying parameters based on moisture 

content, ensuring uniform drying, optimal appearance, and maximum preservation of internal components. This precision drying 

not only enhances herb quality but also significantly boosts economic efficiency.

Technical Advantages and Innovative Features

Modern constant temperature and humidity machines continuously innovate in technology and performance, demonstrating 

notable advantages:

• Precision Control: Utilizing advanced sensor technology and intelligent algorithms, temperature control accuracy reaches

  ±0.5°C, while humidity control achieves ±3%RH, meeting diverse precision operation requirements.

• Energy Efficiency: Incorporating DC inverter technology and heat pump systems, energy efficiency surpasses traditional

  equipment by over 30%, substantially reducing operational costs.

• Smart Connectivity: Supports IoT remote monitoring, enabling multi-unit coordinated control with real-time data uploads

  to the cloud for streamlined production management and quality traceability.

• Adaptability: Modular design enables flexible configuration to suit diverse site conditions, accommodating needs from small

  laboratories to large-scale production facilities.

Conclusion

As precision equipment in environmental control, constant temperature and humidity units play an irreplaceable role across all 

stages—from seed germination to finished product processing. With the deep integration of new technologies like IoT and big 

data, the intelligence and control precision of these units will continue to advance, unlocking greater innovation potential for 

modern agriculture and industrial drying applications.

In the future, constant temperature and humidity technology will deepen its integration with various industries, driving production 

processes toward greater precision, efficiency, and energy savings. This will provide robust technical support for ensuring agricultural 

product quality and safety while elevating industrial processing standards.
