Within our case studies section, you will find a range of case studies that feature our product range and illustrate the various methods we use to successfully handle and move a vast array of ingredients. You can search case studies either by product, by industry or by material.
Until they installed a Spiroflow Aero Mechanical Conveyor, operators at Theakston's brewery used to manually hoist 560 bags of malt up 3 floors. Now the bags are emptied at ground level and the malt is transferred directly into the grist mill significantly improving the efficiency of the operation.
Robert McBride Ltd. manufactures private label household & personal care products. To improve efficiency & eliminate dust in their plant, they needed to eliminate manually loading 50 lb (25 kg) bags of chemicals used to manufacture their descaling gel. Spiroflow provided a bag dump station with a dust hood, a short flexible screw conveyor & an aero mechanical conveyor to do the job. The equipment meets all their needs including their required 6,600 lb/hr (2,994 kg/hr) material conveying rates.
North Carolina based Colony Gums provides the finest quality gums & stabilizers to the food, pharmaceutical & chemical industries. They turned to Spiroflow to increase their conveying capabilities. They now have two side by side powder handling systems that deliver a conveying rate of 20,000 lb/hr (9 tph), with improved productivity, additional safety features, a cleaner environment & reduced product waste.
The basic bag dump station includes an open fronted bag dump cabinet with a dust extraction outlet for connection to a separate dust collector or existing extraction plant. A bag is placed on the mesh support shelf and manually slit. The contents fall directly into the inlet of a flexible screw, aero mechanical or vacuum conveyor. The type and size of the conveyor is determined by the flow rate, conveying distance and flow properties of the product.
The drum dumping system is designed for handling drums of toxic, volatile or dusty materials. The lid of the drum is removed and replaced with a special cone adaptor which incorporates a valve. The drum is then elevated, inverted and locked into a receiving hopper forming a dust tight seal. The valve is opened, allowing the drum contents to empty into the feed hopper and integral flexible screw conveyor. The material can then be fed direct to process machinery, without an operator coming into contact with the material.
Not all materials flow freely from a hopper, storage silo, bin, or other container. Their flow characteristics largely depend on the degree of coarseness in their particle shape and the amount of moisture or semi solid matter in their content. Different solutions to assisting material flow are required as the type of flow aid which may work with one material may not necessarily suit another, or even another grade of the same material. For these reasons, Spiroflow offers a wide selection of flow promoters to suit the characteristics of various materials.
Spiroflow offers a range of Friable Material Conditioners for times when a particular material requires additional ‘conditioning’ ahead of processing or packaging. Our Friable Material Conditioners are furnished with a mesh to ensure only material ‘conditioned’ to the correct specification passes to process or packing. We currently offer 3 standard models: FM100 (2,200 lb/hr), FM200 (4,400 lb/hr) and FM300 (6,600 lb/hr), but special versions can easily be made to fit any size and/or shape of hopper.
