1、 Core Technology: Integration of Efficient Drying and Intelligent Temperature Control

Three dimensional hot air circulation system

The equipment adopts a circulation design of rear air blowing and front return air, combined with mirror stainless steel air ducts, to form a spiral flow of hot air inside the box. This structure ensures temperature uniformity≤±1.5℃Even when handling large quantities of samples, it can avoid problems such as local overheating or insufficient drying.

microcomputerPIDTemperature control technology

Built in high-precision platinum resistance temperature sensor and adaptivePIDAlgorithm, achievable1℃Accurate temperature control. When the set temperature is150℃When the actual temperature fluctuation range is controlled within±0.8℃Within, meet the requirements of medicineGMPCertification imposes strict requirements on drying processes.

Rapid heating and energy-saving design

Adopting efficient methodsUStainless steel heating tube with excellent insulation performance and ultra-fine glass wool filling layer, allowing the box to rise from room temperature to200℃only need15minute Compared to traditional drying ovens, energy consumption is reduced30%Long term use can significantly save operating costs.

2、 Feature: A security solution that adapts to the entire scene

Multi level security protection system

The independent temperature limit alarm system can detect temperatures exceeding the set value2℃Automatically cut off the heating power to prevent sample carbonization. OptionalRS485The interface can connect to a remote monitoring platform, transmit temperature curves in real-time, and achieve safety control when unmanned.

Modular structure and easy to clean design

The inner liner of the box adopts304The stainless steel integrated molding process and the four corner semi-circular transition structure avoid hygiene blind spots. Detachable stainless steel shelf supports free adjustment of spacing, with a maximum load-bearing capacity of15kg/Layer to meet the drying needs of containers of different specifications.

Optimization of experimental operation convenience

left side25mmThe test hole supports external thermometers or data collectors for easy calibration and verification. Built in lighting and observation window design allow for easy observation of sample status without opening the box, reducing heat loss and operational risks.

3、 Typical application scenario: Value extension from laboratory to production line
