Mogensen delivers its 100th vibratory feeder

Micronizing was founded in 1971 by David Newton, the father of today's managing director, following upon his successful development of the concept of cooking cereals and other food grains by means of infra-red radiant energy. The idea of using infra-red energy in this way was not in itself new but the concept was revolutionised in practice by the use of a gas-fired ceramic panel as the infra-red heat source. The company's name is derived from the wavelength of the infra-red energy employed in the process, 1.8 - 3.4 microns. This energy form is extremely efficient at generating heat within suitably absorbent materials and works by causing constituent molecules to vibrate at frequencies in the range 80 - 170 megacycles per second. A surface temperature of 100°C is achieved in less than 45 seconds, and complete cooking takes place in the case of many food grains within 60 seconds. The process has the advantage of converting starches into more easily digestible forms of sugar without either damaging the proteins or significantly reducing the moisture content of the foodstuff. The result is that the nutritional value and flavour are enhanced to a greater degree than is achieved by other cooking processes.
Micronizing has supplied complete plants in over 45 different countries for processing cereals, pulses and oil seeds, including soya and cocoa beans, used in both animal feeds and consumer food products. Throughput capacities range from laboratory volumes up to 8 tph.
Mogensen supplied a range of vibratory feeder models with capacities up to 8000 kg/hr. The feeder is installed below the radiant energy source and ensures, by virtue of the its throwing action, that the food products are evenly cooked, ie, that the whole of the surface of each grain is gradually exposed to the infra-red heat, and that the products remain within the process long enough to achieve the desired degree of cooking but not long enough to incur an undesirable loss of moisture. The feeder drive frame is constructed of mild steel, whereas the conveying tray is of food quality stainless. The underside of the tray is thermally insulated to reduce heat transfer to the drive unit. The insulation also provides the benefit of some reduction in noise levels. All Mogensen feeders are powered by Invicta rotary electric vibrators coupled with inverters and variable speed controls.
