Cinnamon Plant Employs Screen Classifying Cutter and Rotary Mixer

Application Notes & Case Studies /

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

Application Notes & Case Studies /

“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.”

Automated Bag Opening & Batch Mixer Ingredient Preparation System for Various Bakery Ingredients

Application Notes & Case Studies /

Customer that manufactures bakery mixes needed a high-speed batching system for their mixers. Most of their ingredients for their batches are supplied in 50 lb. bags. They wanted to streamline the bag opening process for their blends and be able to store batches in bulk bags so that these would be available to discharge into the mixers when needed. This would avoid having the bag opening process being the bottleneck to their production of bakery mixes. National Bulk Equipment supplied a high-speed sanitary bag opening system operating at a rate of 12 bags/minute to meet the production needs of the customer. Bags were conveyed to the bag opening system by a series of conveyors and a bag elevator. The bag opening system automatically opened and separated out the ingredients from the bags. A series of screens were integrated within the bag opening process to achieve product quality. A bulk bag filling system was provided underneath the discharge of the bag opener. Ingredients discharged into a bulk bag and the empty bags were sent to a compaction unit. These fully batched bulk bags could now be stored and used as needed in their process.

Vocational Service Blends Dry Products for Commercial Bakers with Sanitary Ribbon Blender

Application Notes & Case Studies /

The Munson ribbon blender is a stainless steel food grade unit with a capacity of 65 cu ft (1.84 cu m). Powered by a 25 hp (18.65 kw) electric motor, its 2-to-1 agitator length-to-width ratio yields uniform blends in minimum cycle times. Blending capacity is calculated as approximately 70% to 80% of total vessel volume, leaving ample room for material flow on the upswing side of the agitator.

Munson Machinery Batch Rotary Mixer – Case History – New England Coffee

Application Notes & Case Studies /

After the successful tests, New England Coffee installed a model 700-TH-25-SS rotary batch blender. The stainless steel blender’s drum has a 25-cubic-foot batch volume and a 500-pound capacity. The unit has an internal sprayline to apply liquid flavoring to the coffee beans. The sprayline and nozzles are mounted off-center in the drum. The mixing action continuously replaces the coffee beans in the spray zone so that a thorough coating occurs with no overspraying. The rotary batch blender’s internal lifters and baffles, which provide the blending action, are bolted to brackets that are welded to the drum wall. For more stringent sanitary applications (such as food and pharmaceutical production), the lifters and baffles can be continuously welded to the drum wall.

Rotary Batch Blending of Heavy Metal Powders

Application Notes & Case Studies /

Tumbling action benefits powdered metal application: The rotary mixers consist of a horizontal, rotating drum that has a stationary inlet at one end and a stationary outlet with a discharge gate at the other. The mixing vessel, which has no internal moving parts, is supported by two robust trunion rings, which ride on heavy-duty alloy roller assemblies. Material is loaded through the inlet chute while the drum is rotating.

Tablet IBCs for Pharmaceutical and Nutraceutical Manufacturing

Application Notes & Case Studies /

Handling tablets in larger batches reduces the labor associated with moving containers and making/breaking connections. It leads to improved inventory control and traceability. Matcon Tablet IBCs are designed for the gentle handling of tablets (coated or non-coated) and capsules. The integrated entry spiral lets tablets gently slide into the bin, minimizing the drop height, acceleration and impact thereby reducing any risk of damage.

Tumbling Blends Herbal Supplements Five-Times Faster Than Agitating

Application Notes & Case Studies /

Products are batched according to recipes that may contain between 15 to 60 raw materials, including vitamins, minerals, enzymes, RNA/DNA tissue factors, amino acids, and botanicals. Materials are reduced to the desired particle size in a hammer mill, transported in 44-gal (194 l) lined food-handling containers, and then gravity fed into the Rotary Batch Mixer, a 40 cuft (1132 l) model 700-TS-40-SS from Munson Machinery.
