Breakthrough in the technological paradigm of heat conduction drying for double drum drum scraper dryer
Date: 2025-07-18Read: 12
The dual drum drum scraper dryer developed by Changzhou Xiangteng innovatively adopts a dual drum opposite rotation design. By precisely controlling the speed difference of 0.1-5r/min, a shear force field is formed, which stabilizes the film thickness in the range of 0.3-1.5mm, and improves the drying efficiency by 60% compared to traditional single drum models.
Engineering wisdom of modular architecture
Intelligent temperature control system
The inner part of the drum consists of 12 independent heating chambers, which achieve precise temperature control of ± 1 ℃ through PID algorithm. A production case of vitamin B12 shows that this design increases the retention rate of active ingredients in thermosensitive materials from 78% to 95%.
Dynamic scraper device
The tungsten carbide scraper system equipped with pressure sensors can automatically adjust the bonding pressure of 0.05-0.3MPa according to the viscosity of the material. On the production line of a lithium battery material enterprise in Changzhou, the device has been running continuously for 8000 hours without any scratches on the cylinder surface, which is three times longer than the traditional spring compression type.
MVR thermal energy recovery module
The optional mechanical steam recompression system heats up the secondary steam and returns it to the drum for heating, reducing the comprehensive energy consumption to 1/3 of the traditional spray drying.
Cross industry application graph
Pharmaceutical fieldWhen processing antibiotic residue, adjusting the distance between the double drums to 0.8mm can achieve one-step drying with a moisture content ranging from 85% to 8%, avoiding material loss in traditional multi-stage drying.
new energy materialsSpecially designed roller surface micro texture structure for lithium iron phosphate precursor to prevent material adhesion and increase production capacity.
food processingDuring the drying of soy protein concentrate, dual temperature zone control is used to effectively inhibit the Maillard reaction, resulting in a product color difference value Δ E<3.5.
