Vibrating Feeders

Vibrating feeders include volumetric feeders and gravimetric feeders, also known as loss in weight feeders. The feeders use a vibrating, closed loop, resonant frequency to feed products and materials such as: snack food toppings, dry ingredients, plastics, chemicals, ceramics and more.

They are the feeder of choice for many types of processing applications that include friable or pelleted products that aren’t easily fed by belt or screw feeders.

Add food coating and seasoning machines that use electrostatics to improve product consistency with 100% control of powder coating usage.

Spreading Peanuts on Snack Food Conveyor using Vibratory Feeder

A volumetric vibratory feeder installed over a snack food production line is used to evenly spread peanuts across the width of the conveyor. The peanut pieces are loaded into the feeder supply hopper. The electromagnetic driven vibratory feeder will draw the peanuts out of the hopper at a controlled rate and spread them evenly across the width of the pan. Feed rate is easy adjusted by the controller supplied with the drive with a 1000:1 turndown ratio controlled by the RVS amplitude sensor and feedback loop controller built into the vibratory drive.

adding chocolate chips toppings evenly to food on conveyor with feeder spreader

A multi-channel vibratory feeder evenly adds toppings to edible products that are made in multiple rows. This feeder spreader, also known as a waterfall topping applicator, can accurately dose chocolate chunks, chocolate chips, toffee, almonds, dried fruits, chopped nuts and other toppings to a snack food production line.

Electrostatic Coating System for Cheese Processing Flavoring 1Using an electrostatic coating system can greatly reduce starch powder build-up on cheese processing lines while reducing airborne powder. This will significantly reduce the amount of waste powder during the coating process.

We accurately control the amount of powder (starch) discharged onto the shredded cheese. This feeding system is designed to atomize dry spices, starches, cellulose powders, and other anti-caking agents as they are applied to the shredded cheese rotating in the food coating drum. Located at the discharge of the dosing feeder is a negatively charged electrostatic field to create an electrostatic charge in the powder. This negatively charge field is pointing toward the cheese rotating in the drum. The starch is then attracted to the positively charged cheese rotating in the drum.

Peanut Coating Machine Uses Electrostatics to Add Seasoning

Apply seasoning, spices, sugar and other coatings to peanuts and snack products using electrostatic technology for up to 45% seasoning reduction.  It has been used with peanuts, cashews, macadamia nuts and many other types of fragile snack products like chips, pretzels, pastas, rice, cheese and more.

This type of spice application system can be installed on new or existing machines and systems.

Complete systems are also available for testing purposes to use on-site before final purchase.  Contact us for more information about setting a test system at your production facility.

loss in weight hopper with electromagnetic vibrating feeder

Free standing Loss in Weight Hopper with Feeder includes vibrating feeder to meter material from the surge or supply hopper above the feeder.  The system is mounted on load cells with a scale controller and controls to operate the system. System uses an electromagnetic vibrating feeder with flow control to control the rate of discharge from the feeder. The surge or supply hopper can be sized for each application.

It is used for metering additive materials into a mixer or blending system. It is available in stainless steel or carbon steel construction. Control system is designed for independent control or integrated with an in-house process control system.

automatic box or drum filling system with vibrating densifier

This Automatic Box or Drum Filling System with Vibrating Densifier can be a standalone station or used as part of an existing filling line.

Surge hopper feeds material into the electric powered vibrating feeder which meters the material into a box or drum located on the electric powered roller vibrating table. Box or drum is  vibrated or densified during filling. Load cells with a scale controller and controls operate the vibrating feeder and vibrating table.  These are included as part of the system. Additional powered roller conveyors are available.

Process description: Empty box or drum is indexed into the filling position. Vibrating feeders starts and meters material into the box or drum. During the filling process vibrating table starts to compact the material during the fill cycle. At set point weight the filled box is moved off the filling table.

Vibrating finger screens provide consistently accurate sizing for Waste Wood Recycling.

First, raw Waste Wood material is fed into a variable speed vibrating feeder.  The feed rate is adjusted for product density.  The first vibrating finger screen removes oversized material, which is sent back for shredding.

Next, the material is sent through a fines removal trommel.  Then, it is sent through two finger screens for secondary screening.  Spreader feeders are used for improving material distribution across the width of the finger screens.

Vibrating Tube Feeder Enclosed

This Vibrating Tube Feeder conveys crushed aggregate to a bulk storage silo. It can also be used to convey other types of bulk materials like powders, bulk solids and crushed glass.  The enclosed design prevents foreign materials from entering the product stream.  A variable frequency drive is used to control the feed rate as needed for downstream production requirements.

It is suspended in place by steel cables connected to a structure above. Isolation springs prevent transfer of energy from the feeder to the cables and structure. Abrasion Resistant liners can also be used with this feeder.

Carbon Black Batching System for Seven (7) types of carbon blacks. They are simultaneously fed into individual weigh hoppers. Vibratory Feeders meter product into 16 cu. ft. Net Weigh Hoppers supplied with air-operated fast acting Roller Slide Gates.

Carbon Black Batching SystemUpon discharge, a Quiet Single Impactor Pneumatic Vibrator cleans the Weigh Hopper, before the gate closes. The batch is then transferred by Belt Conveyor to a 16 cu. ft. confirmation (check weigh) Hopper where the final weight is either accepted or rejected. Accepted batches go directly to the mixer. If a batch is out of tolerance it is rejected via a Pantleg Diverter into a portable storage container at floor level.
