SD-18A PRO is the New Inert Loop Spray Dryer suitable for drying both water solution and organic solvent into powder, it’s the module design model which allow user to choose the basic version and to upgrade to inert loop system version in future.
Module design
- User can purchase the closed-circuit system module separately for organic solvent processingin future.
- Quick-release design, closed-circuit system modulecan be removable and connect in one second, use can use air compressor or inert gas to process water-based or organic solvent in one machine.
- Spray dryer can be put on table and also placed in floor to convenient use using.
- Can be connect to Nitrogen generator* or nitrogen bottle.
- Developed base on Labspray® SD-18A flagship mini spray dryer with it excellent configurationand performance.
Main configuration
Inert gas closed loop module main include:
- Double condenser for solvent cooling and recovery
- Can connect to tap water or circulation chiller* base on demand.
- Advance oxygen monitor system to detect the oxygen level make sure easy and more safety.
- Advance bag filter system, full stainless steel chamber, used U.S. Donaldson brand filter core which is best and easy to replace and clean.
Meticulous & stable
- Professional designers surgeon design, patent application has been submitted
- Full body high quality stainless steel material
- Mechanical parts grinding secret agents, only the pursuit of perfection
- S. spray brand Two fluid spray nozzle, SS316 material
- Deblock interval adjustable
- Power supply & Fan imported from Taiwan
- Siemens PLC & Schneider electric components
- LCD touch display from Taiwan

U.S. Spray two-fluid atomizer
- American Spray double fluid nozzle is an excellent high precision spray nozzle. The instrument uses an external mixing nozzle, the air and liquid streams can be individually controlled to effectively spray highly viscous liquids and suspended abrasives.
- Double fluid nozzle is installed at the center of the top of the air distributor and sprays directly down into the tower. The feed enters at a minimum pressure through a tube inlet of the nozzle and is atomized with compressed air.
AIR SUPPLY SYSTEM
- Medium pressure blower imported from Taiwan
- Fan is the internal mechanical structure of the rotor
- The air supply system of the instrument adopts frequency conversion control to realize the stepless adjustment of the air volume, so as to meet the requirements of different process spray drying experiments.
APPLICATION
- SD-18APRO small spray drying apparatus can be used for drying flammable organic solvent as well as aqueous solution and suspension. It is suitable for the experiment and production of uniform powder. Such as: pharmaceuticals, dyes, pigments, food and beverage, milk, egg products plants and vegetable products, heat sensitive materials, plastics, polymers, resins, ceramics, perfume, soap, detergent, blood, adhesives, oxides, textiles, bone, teeth etc.
- SD-18APRO is particularly applicable to the laboratory for liquid material directly into micro powder, without materials filtration, concentrating and crushing before drying, applicable for all solutions such as emulsion, suspension.
