Move from small paper bags to super sacks meets increased product demand.

Dinovite’s bulk filling system has 14 dispensers (seven by two deep). A Rockwell RSView station (far right) communicates batching (filling) information to a PLC, which controls valves at each dispenser. Source: Ingredient Masters.

Ed Lukacevic, a respected breeder and biologist, spent 10 years researching canine diets and nutritional needs and, over that period, developed a recipe that replaces the enzymes cooked out of commercial dog food. The recipe contains all natural ingredients in the form of a powder that customers mix into standard kibble or canned food. 

For four years, Lukacevic made, packed and shipped his product, Dinovite, from his farm in Dry Ridge, KY. Last year, it was time for a new plant and batching system. “With sales of Dinovite dog supplement on a tear,” says Lukacevic, “we purchased a 52,000-sq.-ft. manufacturing plant and decided to see what Ingredient Masters could do for us in the very competitive, and highly regulated, field of canine nutrition.”

Dinovite used to receive its major dry ingredients in 50- and 100-lb. paper bags, but the bags soon became problematic in six areas: inventory management, material handling, ergonomics, spillage, housekeeping and dunnage. Ingredient Masters’ system replaced the bags with 2,000-lb. FIBCs (flexible intermediate bulk containers), which eliminated bag-handling problems. 

Bulk bags containing Dinovite’s major ingredients are bar coded with lot numbers and specifications by each supplier. When the bags are received, bar codes are read to assure the right ingredients are directed to the proper dispensers. Bulk bags are emptied by forklift into one of 14 70-cu.-ft., rotationally molded polyethylene dispensers, each with a computer-controlled valve. 

The system incorporates one bag dump station for the few ingredients that cannot be delivered in bulk bags. Minor ingredients, those used in amounts per batch of less than five pounds, are premixed and added to each batch.   

There is a support structure for the dispensers, which consists of 14 lifting frames to hold a full bulk bag over a full dispenser and a scale cart that spans the length of the configuration. Control of the system, including its robotic scale cart, resides within a Rockwell CompactLogix PLC and RSView HMI software. System recipes reside in a Microsoft SQL database, and each recipe contains ingredients, tolerances and system-specific data such as valve position requirements and vibration sequencing.      

At the start of each batch, the operator selects the recipe to be run, and whether to process one or multiple batches.  The system informs the operator if any required ingredient is missing or unavailable. Initiating a batch activates the scale cart, which drives to the first dispenser and loads. Flow rate and ingredient weight values are accurate to within ±0.2 lbs. The scale then resets and indexes to the second dispenser. When all ingredients are dispensed, a report is created, and the batch bag on the scale cart is lifted off and transferred to the mixer, where it is discharged. 

Following the mix cycle, final product is reloaded into the batch bag and transferred via monorail to the pack-off station where it’s packaged in three-pint jars and one-, three- and five-gallon pails.  A customized label with the dog’s name is applied to each container.  The system is network-compatible and RFID-capable. 

Lukacevic is pleased. “The Ingredient Masters system can process a 2000-lb. Dinovite recipe in five-six minutes-one batch every 10 minutes-to satisfy the demands of the more than 100,000 dog owners who have become repeat customers for Dinovite since 2004.”

Diverter valves

Cyclonaire pinch diverter valves, which are available in diameters from 2 to 12 inches, provide obstruction-free flow of dry materials conveyed under pressure in dilute, semi-dense and dense phase pneumatic systems.  They can direct material to two different destinations or be set up to combine material flows from two different sources. Each valve can be adapted for its application and configured to a specific divergence or convergence.  The valves handle pressures up to 85 psig and may be furnished with flanged, plain or grooved pipe connections with integral pressure switches that indicate flow direction.

Bag dump stations

Constructed with 304 stainless steel, Airlanco bag dump stations are compact, self-contained units built to eliminate the labor, waste and potential health hazards associated with the spillage and dust normally caused when bagged materials are introduced into processing systems. Each station has a large collection hopper equipped with polyester cartridge filters and a 2 hp, 865 cfm fan. When the hopper’s door is opened, the fan automatically starts, ensuring that any dust is drawn through the filter. Programmable pulses of reverse air periodically dislodge the material that collects on the surfaces of the cartridge filters and allow it to fall into the collection hopper.

Bulk bag conditioner

Flexicon’s bulk bag conditioner-unloader system loosens bulk solid material that has solidified during storage and shipment, allowing the material to discharge through a bag spout. Integral configuration of the conditioner eliminates the time, labor and equipment needed for separate loading of bulk bags into a stand-alone conditioner.

Non-stick bucket for conveyors

Gough Econ Inc. has created a heavy-duty, textured bucket for its Swinglink bucket elevator, which improves product release and eliminates the problem of product sticking.  The injection-molded buckets feature a raised inside pattern that decreases surface contact and tension.  The buckets also feature increased strength and rigidity, improved impact characteristics and a longer life with abrasive products.

Bulk bag discharger

The Spiroflow Model T5 bulk bag discharger works in height-restricted areas where the raised forklift frame is higher than actual heights.  The unit uses a special removable frame that reduces the necessary height for forklift tines.  The operator can load the bag and frame at the lower half of the discharger.  The upper frame uses a sealing mechanism that ensures no product loss during discharge.  A special locking system allows easy access to the bag spout through a large viewing porthole.  Multiple options are available for the system including loss-in-weight load cells and pneumatic massage arms.  The discharger is available in carbon steel, stainless steel and an architecture meeting USDA/3A dairy specifications.

Orifice gate valve

Vortex Valves’ Quantum series orifice gate valves handle dry bulk solids in gravity flow, dilute phase or vacuum conveying up to 15 psig (1 bar), depending on size and modifications.  The valves feature a full-flange, weather-resistant design with improved sealing performance. Sizes range from 2 to 14 inches.  The valves’ blade and seal design allows self-cleaning on the opening stroke, which prevents material from packing on internal seals, and inhibits material leakage across the valve or into the atmosphere.

Dust explosion protection

BS&B Pressure Safety Management’s IQR System protects powder and bulk solid process plants and personnel from explosions and flames. The system provides protection against fire and explosions by trapping dust within its mesh lining and absorbing the heat from flames and hot gases.  The mesh works like a heat sink that interrupts the explosion in mid-stream while absorbing pressure waves and dust that would normally be ejected by extremely hot and powerfully vented explosions. The system contains and quenches the explosion and reduces its constituents to water vapor and traces of smoke.

Batching system

This batching system from Ingredient Masters simultaneously processes up to 20 batches per hour, each with up to 24 components. The system works with recipe sizes from 10 to 200 lbs. each and maintains ingredient accuracy of ±0.02 lbs. per ingredient with the use of screw feeders. Systems designed to handle very high ingredient volumes or very large batches can be specified for auto valve release. The transfer conveyor can be scaled for gain-in-weight (which provides slightly higher accuracy) or loss-in-weight (which is faster).  The systems can use as few as four or as many as 30 dispensers, which are each 28 to 105 cu. ft. in capacity.
