Far-infrared drying technology utilizes the principle that materials absorb far-infrared rays with a certain degree of penetration, causing them to heat up internally and lose moisture. This allows for rapid drying of materials, offering advantages such as quality preservation, fast drying, and energy efficiency. It is widely used in universities, enterprises, research institutes, and laboratories for drying, sterilization, and heat treatment. It can also be applied to drying operations in industrial and agricultural production, drying of traditional Chinese medicine materials, and aging, drying, heat treatment, curing, and secondary vulcanization processes in industrial production.
Utilizes new far-infrared heating technology, offering advantages such as rapid drying, zero pollution, and energy saving;
Microcomputer-integrated intelligent temperature control system with PID parameter logic calculation and contactless continuous automatic adjustment of solid-state relay power, automatically completing the operation process according to set parameters;
Large-screen LCD display with three rows of digital displays shows operating temperature, set temperature, constant temperature time, and working status, allowing real-time monitoring of the experimental process;
All models come standard with sensor self-diagnosis function, timing function, over-temperature alarm function, and leakage protection function, ensuring safe, stable, and efficient operation;
Independent fan switch for drying powders or powders of varying densities... For smaller materials, the circulating fan can be turned off, achieving multi-purpose use;
* Employing a self-developed air duct circulation system, it automatically discharges water vapor from inside the chamber, accelerating the drying process and achieving energy saving and consumption reduction;
* The inner liner is made of SUS304 mirror stainless steel with rounded corners. All partitions are removable for easy cleaning;
* The outer shell is made of high-quality cold-rolled steel plate, precision machined by CNC, and then electrostatically powder-coated after phosphate treatment, making it rust-proof and corrosion-resistant;
* The heating element is a far-infrared heating tube, providing stable and uniform heating with a service life of up to 5000 hours;
* The self-locking door lock completes the locking and closing process in one step, making it easy to open and providing good sealing.
* Built-in multi-layer brackets allow for adjustable partition height, effectively utilizing internal space.
