About Us
SINOTHERMO is the international brand of two established Changzhou equipment manufacturers, brought together in 2024 to serve export customers directly — with 20+ years of process engineering behind it.
How SINOTHERMO Began
Two Factories, One Export Brand
On 22 July 2024, Changzhou Xinggan Drying Equipment Co., Ltd. (founded 2002) and Rapidrex Engineering Technology (Changzhou) Co., Ltd. (founded 2006) combined their export operations to form SINOTHERMO Engineering Technology (Changzhou) Co., Ltd.
Both are manufacturers, not traders — each with its own workshops, its own engineering team and its own ISO 9001:2015 certification. Merging the two export businesses put a single English-speaking commercial team in front of international buyers, while the machines continue to be built in the same factories that have been building them for two decades.
That is why a brand registered in 2024 can speak about 20+ years of process experience: the brand is new, the factories are not.

What We Manufacture
Six Equipment Categories, One Powder Process Line
Most projects need more than one machine. Because all six categories are built in-house, a dryer, granulator, pulverizer and mixer can be specified as one line — matched on capacity, material contact surfaces and control philosophy.
Conduction and Vacuum Dryer
Vacuum and conduction technologies dry materials gently — reduced chamber pressure and a low-temperature environment remove moisture without damaging heat-sensitive or hygroscopic materials.
View equipment→Convection Dryer
Fast, uniform drying by direct contact between hot air and material — spray, flash, fluidized-bed, belt and tray configurations for continuous production.
View equipment→Granulator and Coater
Wet, dry and fluid-bed granulation equipment producing uniform, free-flowing granules for tablets, instant powders and engineered particles.
View equipment→Mixer
Ribbon, conical, sigma and V-type mixers for homogeneous blending of powders, granules and pastes — from gentle low-shear blending to high-speed mixing.
View equipment→Freeze Dryer
Laboratory to industrial lyophilizers that preserve structure, activity and flavor by drying under vacuum at low temperature.
View equipment→Pulverizer
Coarse and fine size-reduction equipment down to micron-level particle sizes, for herbs, chemicals, foods and minerals.

R&D, Manufacturing, Technical Service and Global Reach
01
Research & Development
Customised material testing is the front end of every project. Rather than selling from a catalogue, we run your material first and let the trial data decide the configuration.
02
Manufacturing & Quality Control
Production stays in our own workshops, so inspection happens at every stage rather than only on the finished machine. Both manufacturing entities hold ISO 9001:2015.
03
Technical Services
Existing designs keep being developed rather than frozen — the aim is equipment that hits the process target precisely, not equipment that merely ships.
04
Global Reach
One export team, two factories' capacity. International customers get a single commercial contact with direct access to the engineers who build the machine.
Verifiable, Not Just Claimed
Where to Check Our Work
Patent Wall
CNIPA-granted utility model certificates covering specific machines — belt dryers, 3D motion mixers and more. Certificate numbers are published so they can be looked up independently.
See the certificates→Testing Laboratory
Pilot-scale dryers, granulators, mixers and pulverizers you can run your own material on, plus particle-size and moisture analysis — trial data before you commit to a machine.

Where We Are
Changzhou, Jiangsu
Everything is designed and built in Changzhou, Jiangsu — part of the Yangtze River Delta manufacturing belt, about ninety minutes from Shanghai by high-speed rail. Customers are welcome to visit, witness a factory acceptance test, or run a trial in the lab before shipment.
