Extruder barrel liner replacement cost halved

New technology has cut the cost of Baker Perkins MPF food and MP industrial extruder barrel liner replacement by up to 50%. By making liner replacements easier to fit as well as enabling only the worn sections to be replaced, the cost, complexity and downtime needed to replace barrel liners have all been significantly reduced. These extruders are used widely in the snacks and breakfast cereal, powder coating and plastics sectors. The savings are achieved by replacing the original one-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 Baker Perkins’ factory-trained engineers. However, subsequent liner replacements can be undertaken by the customer’s own engineers in a fraction of the time, saving both cost and plant downtime. Additional cost savings are achieved either by replacing only worn sections of the liner, or by upgrading the liner insert material only in high wear areas of the barrel to extend its life. A barrel retrofit also involves replacing cartridge heaters with the latest slab heaters, which are easier to replace and provide improved heat distribution and longer life. The time span between liner replacements on food extruders varies depending on processing conditions such as the abrasiveness of the product, throughput and torque, but can be annual. Baker Perkins MPF extruders frequently have a production life of more than 20 years, so cost of ownership savings are considerable. Additional upgrades for MPF food extruders include barrel extensions for increased mixing capacity and raw material processing; changing the shaft type from round to hex; and improving barrel opening and closing using a hydraulic barrel actuator.
