Laboratory Aqueous‑system Spray Dryer

The laboratory aqueous‑system spray dryer is developed for universities, research institutes, pharmaceutical, food and chemical enterprise laboratories, dedicated to micro‑scale and small‑batch granular powder preparation. It features broad compatibility for solutions, emulsions and suspensions. It is especially suitable for drying heat‑sensitive materials, such as biological products, biological pesticides and enzyme preparations.

After atomization, materials are exposed to high temperature only for a very short moment as fine droplets. This instant‑heating drying mode maximally preserves active components without thermal degradation. It acts as core experimental equipment for new‑material research, lithium‑ion battery materials, pharmaceutical and food sample development. Two collection chambers are available: glass chamber and stainless‑steel chamber, freely selectable according to material corrosiveness and experimental conditions.

✅ SUS304 stainless‑steel construction & human‑oriented layout

The whole main unit is built with SUS304 stainless‑steel. Compact footprint saves lab space. Buttons, temperature meters and air pipelines follow ergonomic design. Quick‑disconnect connectors simplify disassembly and cleaning, well‑suited for frequent sample switching in laboratory work.

✅ Integrated PLC & 7‑inch touch screen control system

Equipped with PLC controller and 7‑inch touch panel for one‑click full‑machine operation. Inlet air temperature, outlet air temperature and all process parameters can be set and monitored in real‑time on screen. Visualized data lowers operation barriers for fast process debugging.

✅ Standard‑grade electrical components for stable performance

All electrical parts including air switches, relays, protectors and push‑buttons adopt high‑quality original components. It ensures long‑term safe and stable operation, extends service life and reduces maintenance frequency.

✅ High‑power heater & PID constant‑temperature control for precise temperature

Fitted with 3.5 kW customized heater together with real‑time PID temperature regulation algorithm. Temperature accuracy reaches ±1℃ with minor fluctuation. Consistent drying conditions are guaranteed batch‑to‑batch for repeatable and comparable experimental results.

✅ Variable‑frequency fan system for diversified material processes

Fan rotating speed and air pressure are adjustable. Since atomizing effect and product yield are closely related to air volume, variable‑frequency adjustment allows researchers to obtain optimal air‑flow setting for lithium‑battery precursors, protein, polysaccharides, chemical powders and other substances.

✅ Two‑fluid atomizing structure with automatic nozzle anti‑blocking pin

Proven two‑fluid atomizing structure, compact and easy for maintenance. Built‑in automatic cleaning pin clears nozzle blockage automatically. Users can adjust pin movement frequency to reduce manual disassembly and sustain continuous experiments.

✅ Uniform powder particles with excellent flowability

Spray‑dried powder presents normal particle‑size distribution with great flowability. Over 95 % of finished dry powder falls within identical particle‑size range. Stable powder quality meets lab requirements for particle morphology and particle‑size consistency.

✅ Wide feeding‑rate range, support micro‑volume sample test

Feeding volume is precisely controlled by peristaltic pump. Minimum sample volume reaches 80 ml, maximum feeding capacity hits 2 L/h. Operators can adjust feeding speed based on material viscosity, solid content and experimental objectives, covering micro‑lab‑test and small‑batch sample production.

✅ Built‑in oil‑free air compressor, low noise for lab environment

Integrated oil‑free air compressor eliminates external air source requirement. Operating noise is lower than 60 dB, complying with national laboratory noise standards. It can be placed directly on ordinary lab benches without extra gas‑source reconstruction.

✅ Reliable shutdown protection to prevent mis‑operation damage

Special shutdown protection logic: after pressing stop button, all components stop immediately except cooling fan. It effectively prevents heater burnout caused by forced power‑off by human error and protects hardware from improper operation.

Widely adopted in university labs, research institutes and enterprise R&D centers. Covering lithium‑ion new‑energy materials, fine chemicals, biomedicine, food processing, biological pesticides, enzyme preparations and nanomaterials. It supports formula development, process exploration and sample preparation, and provides credible pre‑experimental data for pilot‑scale and mass‑production projects.
