Description
This mini spray dryer is designed for easy selection and adjustment of all functions, allowing for rapid achievement of optimal spray drying conditions.
Direct drying of the sample, from solvent and suspension to a micronized powder, significantly reduces the pretreatment and posttreatment operations traditionally associated with powder production, such as filtration, separation, and spraying, and eliminates contamination during these processes.
Advantages
- Instantaneous heating of the microparticle sample ensures that even heat-stable samples are not oxidized and that a uniform fine powder is obtained.
- The sprayed micro-powders are low in moisture, non-oxidizing and non-contaminating.
- The product is dried directly from the solution or suspension sample into a fine powder without the pre-treatment and post-treatment operations of filtration, separation, and grinding associated with conventional drying methods, and eliminates the contamination problems caused by these operations.
- It can be connected to the GAS411C organic solvent recovery unit to handle organic solvents.
- The drying chamber, cyclone, etc. are of quick assembly construction, further enhancing operability.
- A lifting platform is provided as standard for attaching and detaching accessories.
- The machine is equipped with an outlet for stirrer power (2A) to facilitate stirring of suspensions while feeding samples.
- The unique peristaltic feed pump, nozzle cooling mechanism, pulsed nozzle cleaning mechanism, and anti-clogging stabbing needle provide a wide variety of spray conditions and stability.
