ProSpect Analytical introduces RP-200 in-line NIR analyzer/sampler for powders
PLYMOUTH, Minn. -- ProSpect Analytical recently introduced a new ProSpect RP-200 in-line near infrared reflectance (NIR) analyzer/sampler for dairy powders. RP-200 delivers accurate predictions of moisture, protein, fat and other organic constituent concentrations in real time.
Designed for powder processing applications, the state-of-the-art RP-200 requires very little maintenance and operator involvement, notes George Hutson, founder, ProSpect Analytical.
"In-line sampling and analysis save time and eliminate waste with accuracy equal to laboratory methods," Hutson says.
He adds that the RP-200 maximizes dryer performance, reduces product giveaway and out of spec product, and ensures product compliance to customers' specifications.
The combined unit is installed directly on the dryer, typically in the area just after the fluid bed in a position where the powder is "free falling," he notes.
A hygienic receptacle is inserted directly into the process line to retrieve a 1-ounce powder sample for analysis. The receptacle then retracts into the scan chamber via a doctor plate to produce a smooth sample surface.
Fiber optic source and return cables retrieve the unique light energy signature for that sample, Hutson says.
The NIR spectrometer measures the diffusely reflected energy from the sample collected. The amount of energy reflected is directly related to the concentration of each constituent, such as the moisture and protein in the product, he says.
After the scan is complete, the receptacle returns to the process line and discharges the sample back into the production flow or, alternatively, into a specially designed container for transport to the laboratory for testing and confirmation of the constituent values, he adds. The data collected is used to simultaneously calculate the level of concentration of each constituent in the sample.
Designed by process experts with more than 30 years of industry experience, ProSpect's analyzers work with existing programmable logic controllers (PLC)/Control platforms and seamlessly integrate within any existing process system, Hutson notes. Data is communicated to the factory PLC as often as every 60 seconds to facilitate automated adjustments for optimized process control.
Engineered to withstand moisture, vibrations and temperature extremes in the harsh conditions of any production environment, the sanitary sampler components comply with 3-A Sanitary Standards, and the air conditioned, waterproof, shock mounted, hygienic stainless steel enclosure meets NEMA 4X standards, Hutson adds.
