Spray dryer LABSPRAY MINI LOOP

continuouslaboratoryfor pilot plants

Product Overview

• Inert gas loop system replaces air to prevent ignition and explosion risks.
• Explosion protection at source for enhanced safety.
• Oxygen content monitoring system.
• Multi-condensing solvent recovery system.
• Bag filter to improve yield and prevent particulate emissions.
• Automatic operation with touch screen; multiple nozzle options available.

Summary
LABSPRAY MINI LOOP Lab inert-loop spray dryer is designed for use with organic solvents. It employs a nitrogen (N2) closed-loop inert gas medium instead of ambient air for spray drying, allowing recovery of both powder product and solvent. The unit is intended for low flash point, flammable, slightly toxic or oxidizable materials and provides a closed-loop solution for laboratory and pilot-scale drying tests.

Applications
Standard laboratory/pilot spray dryer suitable for water-based solutions and organic solvents. Ideal for drying tests of low‑flash‑point, flammable, slightly toxic or oxidizable materials where solvent recovery and oxygen control are required.

Features

• Color LCD touch screen: displays inlet/outlet temperatures, peristaltic pump speed, air volume, etc.
• Touch-screen control with one-button start and process parameter setup; process animation displayed on screen.
• Manual control mode to adjust parameters during experiments; dynamic real-time process display.
• Spray, drying and collection components in high-grade stainless steel to ensure contamination-free drying.
• Two-fluid atomization; compact design without need for auxiliary equipment.
• PID real-time temperature control; temperature accuracy ±0.5°C.
• Air inlet filter to maintain sample purity.
• Peristaltic pump feeding, adjustable feed rate; minimum sample volume: 50 ml.
• Uniform particle size distribution; >95% of dry powder within same size range.
• Equipped with oxygen content detector to monitor internal oxygen for safe operation.
