Used Hemraj PSD 02 Stainless Steel Spray Dryer – 22 Lb/Hr Water Evaporation, Two-Fluid Nozzle Atomization

Manufacturer Information
Hemraj
Hemraj manufactures industrial processing equipment for drying and powder-production applications. The PSD 02 spray dryer is designed to convert compatible liquid feeds, solutions, suspensions, or slurries into dry powders through atomization into a controlled stream of heated air.
This unit features 316 stainless steel product-contact parts and 304 stainless steel non-contact components, making it suitable for compatible sanitary, chemical, agricultural, food ingredient, and specialty powder-processing applications.
Description
Available for sale is a used Hemraj Model PSD 02 spray dryer, built in 2014, with a rated water evaporation capacity of approximately 10 kg/hr (22 lb/hr).
The drying chamber measures approximately 36" diameter x 69" straight side and features 316 stainless steel product-contact parts, with non-product-contact components constructed of 304 stainless steel.
Atomization is accomplished through a two-fluid compressed-air nozzle, creating fine droplets of the liquid feed for rapid moisture evaporation inside the drying chamber. At a feed containing approximately 30% dry solids, the system has a stated feed rate of approximately 14.5 kg/hr (32 lb/hr) and powder production rate of approximately 4.5 kg/hr (10 lb/hr).
The system is designed for an inlet temperature ranging from ambient up to approximately 260°C (500°F), with a stated outlet temperature of approximately 95–100°C (203–212°F). Heat is supplied by an electric air heater.
Powder is recovered using a "blown down" powder collection method. Design conditions include approximately 30–40°C (86–104°F) ambient temperature, 760 mm Hg atmospheric pressure, and 50% relative humidity.
Previously used in the production of organic biopesticides, this Hemraj PSD 02 may be suitable for research, pilot, specialty chemical, agricultural, and other lower-throughput powder-production applications.

Frequently Asked Questions

What is the evaporation capacity? The Hemraj PSD 02 has a stated water evaporation capacity of approximately 10 kg/hr, or 22 lb/hr.

How much finished powder can it produce? At the stated design basis of approximately 30% dry solids, the specified powder rate is approximately 4.5 kg/hr (10 lb/hr) from a 14.5 kg/hr feed rate.

What type of atomizer does it use? The dryer uses a two-fluid compressed-air nozzle atomizer, which atomizes the liquid feed into fine droplets for rapid drying.

What materials are used in construction? Product-contact components are 316 stainless steel, while non-product-contact components are 304 stainless steel.

What was the spray dryer previously used for? The unit was previously used for organic biopesticides. Buyers should evaluate cleaning requirements and material compatibility before introducing a new product.

Can Aaron Equipment assist with shipping and logistics? Yes. Aaron Equipment can assist with dismantling and rigging coordination, loading, domestic and international freight, and logistics planning for spray dryers and other industrial process equipment.
