Because it has made barrel liner replacements easier to fit, Baker Perkins has reduced the cost of replacing the liner on its MPF food extruders by as much as 50%. It also enabled only one section to be replaced, reducing the cost, complexity and downtime needed. The savings are achieved by replacing the original 1-piece liner with a backing block and a liner comprising a number of individual inserts. Like previous liner replacements, this is a high-precision operation requiring specialist equipment and is best carried out by the company’s factory-trained engineers. However, subsequent liner replacements can be undertaken by processors’ own engineers in a fraction of the time, saving both cost and plant downtime. Phone (616) 784-3111;
