Eriez vibratory feeders are commonly used to meter nuts into downstream processing equipment, acting as bulk metering devices to provide the nuts at a controllable, easily adjusted rate. The feeders are also used to sprinkle salt, sugar, or other seasonings during nut processing. Eriez electromagnetic feeders are offered in various models and designs to meet specific application requirements.
Eriez HD (high-deflection) vibratory feeders combine the higher tray deflection and lower frequency advantages of mechanical feeders with the trouble-free service and adjustability of electromagnetic feeders. When screening is required to remove undersize material, such as excess salt or oversize materials, the higher tray deflection of HD models is ideal. HD feeders are commonly utilized in nut processing applications when gentle feeding is critical.
“Softer nuts, such as walnuts, can be handled by this model with very little to no marking to the skins,” Eriez Vibratory/Screening Product Manager Rob Yandrick explains. Yandrick also notes that Eriez’ team of experts work closely with nut processors to ensure the ideal feeders are incorporated throughout their facilities to maximize efficiency and meet any unique application challenges.
Eriez HS (high-speed) vibratory feeders are specifically designed for fast feed rates and offer extremely fast startup and shutdown, making these models excellent for nut packaging applications. They provide greater economy and efficiency in feeding and filling and are ideal for use in conjunction with weigh scale and packaging machines. These compact and functional units can be installed easily in small spaces.
Eriez Model C feeders accurately feed and control material flows ranging from a few lb per minute to many tons per hour. These units have no rotating parts to wear out and feature AC-operated, electromagnetic drives, which consume up to 60% less energy than competitive DC drives.
One of the primary benefits of vibratory feeders in the nut processing industry is the simple and clean construction of the feeder tray. The trays can be easily and quickly wiped down or washed out for product changeover or sanitation protocols, according to Yandrick. “For nuts that tend to deposit residue on equipment, feeder trays can be provided with polished material contact surface to minimize any buildup. As compared to belts or screws, feeders offer a more sanitary approach.”
