In modern manufacturing, high importance is attached to the processor‘s ability to provide extended shelf life for food products; including powdered or granular products. Modified Atmosphere Processing (M.A.P.) Systems remove oxygen and replace it with inert gases. Colby can help. We can provide a range of M.A.P. systems for all your needs; for both retail and...

The Colby Vacuumaster cost-effectively extends product shelf life by removing oxygen from retail containers of oxygen sensitive powdered and granular products. Your product will remain fresher for longer because the Vacuumaster achieves very low levels of residual oxygen. The system is economic to buy and run. It is...

V A C U U M A S T E R T H E S E C R E T I S S I M P L I C I T Y Suits high and low throughputs: Configurations of 1, 2, 3 or 4 chambers or 2 appropriately sized machines working in parallel, allow the Vacuumaster to be tailored to suit throughputs of 20 to 400 cans per minute. S I M P L E Y E T S M A R T C O N T R O L S The Colby Vacuumaster operates totally automatically. All the operator has to do to begin daily operation is press the "START" button. Sensors throughout the system monitor and precisely control all functions through each cycle. If a problem should occur, in-built...

A Simple Semi Automatic System Fully Automatic Batch M.A.P. System A S I M P L E C O M PA C T M A C H I N E The Colby Vacuumaster is more compact than conventional machines. The rectangular shape allows it to fit neatly within almost any layout and containers are delivered and taken away by simple straight conveyors. T I M E P R O V E N T E C H N O L O G Y The Colby Vacuumaster's compact, functional design and sheer simplicity offers low cost, low gas consumption, quick changeover and minimal maintenance. The system has been used by companies throughout the world since 1974. Leading brands...

T E C H N O L O G Y F O R R E T A I L P R O D U C T S By eliminating a number of steps from the inert gassing process and reducing the number of mechanical elements, system reliability and uptime are substantially improved, while the capital cost is significantly lowered. The Colby pre-gassing system is also very space efficient, reducing the requirement for environmental control and air-conditioning in new installations and freeing up additional space in existing...

To minimise product segregation, the system uses laminar flow through the powder. Accurate operation is maintained through the use of a large gas infusion surface and integral oxygen analysers which constantly monitor the R.O. level of the powder and feed...

F I L L I N G A C C U R A C Y The process of pre-gassing can cause changes in the density of powders by compaction and stratification. The Colby system however, carefully regulates the flow and pressure of the inert gas and utilises a number of sensors throughout the system to ensure that every can of product meets the most exacting quality standards. R E J E C T S One of the drawbacks with pre-gassing systems has been that it is often difficult to reject cans without affecting the integrity of the inert environment. The alternative of rejecting the cans after seaming is not viable. The...

ColbyMap is a proven method of removing oxygen from bulk quantities of powders and granules before they are packed. It achieves spectacularly low levels of R.O. at a higher speed and lower cost than other systems. It can be used to extend the shelf life of whole milk powders, baby formulaes, nutritional supplements and other powders and granular products. The highest product quality can be maintained by gassing it...

H O W C O L B Y M A P W O R K S The extraction of oxygen and injection of an inert gas has long been recognised as the best way to improve the product shelf life. The ColbyMap system uses a vacuum to evacuate the gassing chamber. Nitrogen is then flushed through the powder. Oxygen removal is so effective that even after several days in bulk storage, R.O. levels as low as 0.5% are achieved. In a typical 250 kg (550 lb) batch, the entire gassing cycle takes less than two minutes. ColbyMap systems have sophisticated controls that are pre-programmed and easy to use. The whole operation is...
