Manufacturer Information

Manufacturer: EnviroStar Model: ES 500 Equipment Type: Centrifugal Spray Dryer

EnviroStar spray drying equipment is designed for converting compatible liquid feeds, solutions, suspensions, and emulsions into dry powders through controlled atomization and heated-air drying.

The EnviroStar ES 500 features a stainless steel drying chamber, rotary atomization technology, integrated powder collection, and automated process controls.

This unit incorporates 304 stainless steel construction, Allen-Bradley PLC and HMI controls, HEPA-filtered inlet air, and a stated drying capacity of up to 2.0 kg per hour.

Description

Available for sale is a used EnviroStar Model ES 500 centrifugal spray dryer, designed for laboratory, research and development, pilot-scale production, and small-batch industrial spray drying applications.

The unit features a 304 stainless steel drying chamber measuring approximately 41-1/2" in diameter x 36" straight side, with a 26" conical bottom and 3" center bottom outlet.

The system has a stated drying capacity of up to 2.0 kg per hour and operates with an inlet air temperature of 350°F.

A rotary atomizer disperses liquid feed into fine droplets within the heated drying chamber, allowing moisture or compatible solvents to evaporate and leaving dried particulate material for collection.

The system includes a vacuum exhaust blower with collection cyclone, along with a high-efficiency collection cyclone equipped with integrated lighting and inspection ports for monitoring the collection process.

An Allen-Bradley PLC and HMI provide process control and operator interaction. The system also incorporates HEPA inlet air filtration.

Utility requirements include 5 CFM compressed air at 45 PSI and atomizer cooling water at approximately 1 liter per minute through a 1/4" poly line.

Main dryer electrical requirements are 208/240V, 3-phase, 50/60 Hz, 54 amps. The peristaltic pump requires either 110V, 2A or 220V, 1A, at 50/60 Hz.

The equipment is described as having an FDA-compliant design and UL certification, with certification scope and documentation to be verified.

This EnviroStar ES 500 could be suitable for powder development, food ingredient processing, specialty chemical drying, pharmaceutical research, and other compatible spray drying applications.

Specifications

Drying capacity should be confirmed as feed throughput or moisture evaporation capacity. Actual production rates depend on feed solids, viscosity, inlet and outlet temperatures, atomizer settings, desired final moisture, and product characteristics.
