High Speed Centrifugal Spray Dryer

High Speed Centrifugal Spray Dryer

Drying delicate bio-compounds, pharmaceutical intermediates, and heat-sensitive organic materials requires precise thermal management to prevent denaturation, active component degradation, or color alteration. The LPSD-3L Pro High Speed Centrifugal Spray Dryer provides a controlled, rapid-evaporation environment that preserves the biological and chemical activity of sensitive materials while producing clean, high-purity dry powders.

High Speed Centrifugal Spray Dryer Structure

Equipped with an adjustable high-speed centrifugal atomizer reaching up to 36,000 r/min and a variable-speed peristaltic pump feeding system, the LPSD-3L Pro High Speed Centrifugal Spray Dryer allows precise fine-tuning of droplet diameter, final particle size, bulk density, and residual moisture levels.

• Filtered Air Preparation: Air is scrubbed through high-efficiency filters before entering the 6 kW heating stage, ensuring zero ambient contamination in technical powders.
• Spiral Distribution: The air distributor creates an optimized helical flow inside the drying chamber, keeping particles suspended until fully dry.
• Instantaneous Mass Transfer: With a 1.0–1.5 second residence time, liquid suspensions, slurries, and solutions are instantly converted into dry powder.
• Efficient Separation: Coarse powders drop directly into the stainless-steel collection jar, while fine fractions and exhaust gases are managed cleanly by the 0.75 kW draft fan.

High Speed Centrifugal Spray Dryer Application

Widely applicable for egg products, milk and dairy derivatives, tannic acid, plant extracts, herbal concentrates, slaughterhouse by-products, blood meal, fish protein hydrolysates, herbicides, and biopesticides.

RFQ

Q1: Can the LPSD-3L Pro dry heat-sensitive biological samples? Yes, the unit is designed for gentle drying; it features an average drying time of just 1.0–1.5 seconds and an adjustable inlet temperature as low as 30°C to minimize thermal stress. However, as biological materials vary in their properties, please verify performance using your specific material before relying on the results.

Q2: What is the minimum feed volume for valuable extracts? The minimum feed volume is just 50 mL, making it ideal for processing rare or expensive extracts and biological products.

Q3: How is powder fineness adjusted? The rotary atomizer operates at speeds up to 36,000 rpm; by adjusting this speed alongside feed rate and temperature settings, you can precisely control droplet size and the characteristics of the final powder.

Q4: Can the unit handle high-viscosity extracts? Rotary atomization technology generally accommodates a wider viscosity range than simple nozzle systems, though suitability depends on your specific feed material-we recommend confirming this through testing.

Q5: Does the unit support low-temperature drying? Yes. Inlet temperatures can be set between 30°C and 300°C, and outlet temperatures between 30°C and 140°C, enabling low-temperature, gentle drying processes.

Q6: What is the evaporation capacity for plant extracts? Specific evaporation capacity depends on the feed's solids content, concentration, and process parameters-please confirm testing conditions with us before evaluating yield.
