Powdered Drink Mix Blending and Packaging System

A customer was building a new facility that had a room dedicated for use in their powder blending process. They contacted NBE to help develop a solution that will meet their process needs and fit inside the space they have available. The system needed to handle raw ingredients from supersacks as well as small bags. Recipes were based on even numbers of the raw material packages. All of the material must be discharged, screened to prevent any contaminants, and discharged into a horizontal ribbon blender. Attention must be paid to ergonomic handling of the materials, including the scissor lift for bag positioning, along with disposal of the empty packaging from the upper levels of the system. The finished blends were packaged in super sacks that will ultimately be used to supply their packaging line. NBE designed and manufactured a custom three-level platform to support all of the equipment in the available space. NBE coordinated with the customer’s dust collection vendor once the system was assembled in our facility. The vendor came and installed the vent lines under the platform structure in our facility. The customer visited for a final inspection of the completed system assembly prior to shipment and was very pleased with the finished product.

Conveying Grape Waste at Winery with Screw Conveyor

Stainless steel construction was used to prevent corrosion, and continuous welds were provided to prevent debris from building up between the pipe and flight connection. Flush out ports were added to the side of the troughs to allow residual grape juice and cleaning fluids to drain freely. Hip roof covers were used on the conveyor section located outside the building to prevent rain from collecting on the housing. To work within the required space constraints, a shafted horizontal conveyor was custom designed to feed directly into an inclined shaftless conveyor in place of using a CEMA standard inlet and discharge connection. The shaftless conveyor utilized a dual spiral shaftless screw to ensure that the grape pomace conveyed easily up the incline.

Distillery Goes Green with Centrifugal Separation of Stillage

Grain solids unable to pass through screen apertures are propelled in a helical pattern through the screen cylinder until being discharged through its open end, into a chute that funnels the dewatered solids into a plastic tote on a pallet below. When a tote is full with about 2,500 lb (1,136 kg) of the damp grain, a pallet truck replaces it with an empty tote. The full totes are stored in a holding area to be picked-up by a farmer.

Metering and Conveying Spent Brewer’s Grain Using Screw Conveyor

The conveying system previously in place, progressive cavity pumps, proved to be a significant and consistent maintenance problem resulting in brewing downtime. KWS replaced the problematic pumps with four inclined screw feeders to meter the spent grain out of the collection bins below the filter presses. These four inclined screw feeders meter the spent grain to a single collection screw conveyor that transports the grain to another system of screw conveyors that conveys the grain to its final destination.

Spice Maker Adds Paddle Mixer to Quadruple Production

A typical batch consists of 10 to 12 ingredients, including liquid additions. The ingredients, mostly spices and salt, are received in 50 lb (22.7 kg) bags or boxes, which are moved by forklift onto a mezzanine and manually loaded into the mixer below. When a batch is completed it is discharged into 1,500 lb (680 kg) bulk bags, from which the product is packaged in 50 lb (22.7 kg) or 75 lb (34 kg) boxes, or 125 lb (56.7 kg) drums.

Formerly, packaging was a manual operation in which each bag was lifted by a hoist and emptied into the packages. In the new system, each bag is moved by forklift to a bulk-bag discharger, from which it is emptied into a hopper that serves two packaging lines via vibratory feed troughs. Each trough feeds product directly into a package that is set on a scale, and the flow is automatically controlled by a gain-in-weight system.

Cinnamon Plant Employs Screen Classifying Cutter and Rotary Mixer

From the conveyor line the quills are discharged into a rotary knife cutter and rough-cut to a maximum length of 6 in. (15 cm). The quills are then fed via a pneumatic conveyor into a high-speed, screen classifying cutter (Munson model SCC-15-MS). The unit’s horizontal rotor contains dozens of cutter blades, attached to a helical array of staggered holders called “interconnected parallelograms.” The blades are chisel-shaped, with replaceable carbon tips.

Driven by a 20-hp (15-kW) motor, the blades rotate at 2,200 rpm and continuously shear the quills against twin, stationary bed knives, cutting them into 2 in. (5 cm) lengths. Despite the high rotation speed, there is little to no heat generation and minimum fines

Switch to Rotary Batch Mixer Cuts Costs, Boosts Output at Food Ingredient Processor

“When we decided to increase our capacity we specified a Munson Model 700 stainless steel rotary batch mixer with a 140 cu ft (3.96 cu m) capacity. It accommodates our batch weights of 5500 lb (2,500 kg), in excess of what a cone blender can handle. Because the drum rotates on external trunnion rings, there is no internal shaft with seals immersed in the material, eliminating a maintenance and cross-contamination problem. In addition, the mixer evacuates upon discharge with little or no residual, allowing rapid, thorough cleaning.”
