The company also supplies agricultural product processing and construction equipment. Among its leading products are millbank extrusion technology for production of feeds for various types of livestock; destek edible oil production technology; and Bigfoot and Hydraform brick and blockmaking equipment.
Millbank extrusion technology for production of feeds for various types of livestock, including pigs, cattle and fish. The dry extruder is a fast reaction cooker reaching high temperatures within seconds. The process uses no external heat source, relying on the friction and pressure created within the oxygen-free atmosphere in the barrel. The cooking performance can be varied, giving the ability to expand ingredients, gelatinize starch and destroy inhibitors where they are present. A major benefit is that no steam boilers or dryers are required to carry out the process.
The Millbank dry extruders are available with either 55kW or 75kW electric motors; the former costs about $14,000 for the complete machine. Turnkey plants designed for individual needs are also available – these can include coolers, augers, conveyors, sifters, mixers and bagging-off equipment.
Destek edible oil production technology, ranging in processing capacities from 80kg to 300kg of oilseeds per hour. The Destek system was primarily developed to provide farmers, entrepreneurs and rural communities with affordable opportunities to produce sunflower oil on a semi-commercial scale. It produces cold-pressed oil with a light sunflower aroma and pleasant, sweet taste.
Generally the oil is not sold in a raw form, but is at least filtered and possibly (depending on the market) also deodorized. A basic 80kg/hour system of oil expeller and filter press costs about $6,500; a complete 3,090 kg/hour production system comprising dehuller, expeller, filtration system (with centrifugal filter and filter press) and deodorisation unit costs about $50,000.
Gert Lubbe of Destek Design Consultants, who designed the system, says the cost of these machines is about a third of that of equivalent production units from Europe. He also claims that the Destek equipment is more robust in handling stones, for instance, and therefore more suited to African conditions than overseas machines. The equipment can also be used to process other oil seeds like soybeans, groundnuts, pumpkin seeds and others.
Bigfoot and Hydraform brick and blockmaking equipment which covers the technology spectrum from hand-operated conventional cement brick production equipment to semi-automatic hydraulic soil-cement machines. The Bigfoot brickmakers are manually operated egg-laying type machines with exchangeable moulds for the production of a full range of building blocks, bricks and pavers of the highest quality, according to Shepherd. The machines are characterized by their robust construction with few moving parts, ease of operation by even unskilled operators and versatility for the production of a range of bricks/blocks.
The basic Mark 2 machine produces 12 stock bricks per drop, has a production capacity of up to 6,000 stock bricks per day and costs less than $1,400 for the complete machine with wheelbarrow and accessories. The Hydraform building system replaces conventional bricks and mortar by the use of Hydraform blocks which are manufactured by hydraulically compressing a soil and cement mixture in a Hydraform blockmaking machine. The machines are powered by either diesel engine, electric motor or an independent power source such as a tractor. Production capacities range from 100 to 220 blocks per hour. The cost of the M5 Mark 3 machine with a 10kW Hertz diesel engine – the most popular model in the range – is about $10,000. This model comes on a trailer chassis for towing behind a light delivery vehicle. It produces 220 blocks of 220 x 240 x 115 mm per hour. Hydraform blockmakers have been sold in Argentina, India and many African countries, Shepherd says. Their use is predominantly in the construction of housing, schools, clinics and general single and multi-storey buildings.
