OVENS AND PRODUCTION LINES

With the issues currently surrounding the escalating cost and environmental implications of conventional fuel options, some bakeries may be interested in investigating different fuel options. For several years Brook Food and Bakery Equipment has been working on making the choice of wood pellets as a fuel a more convenient choice. It has developed a range of pellet tanks and feed systems with a small footprint for the ancillary equipment required for this

Looking at the benefits of a planned maintenance programme


Ovens often control the productivity of a line so it is important to keep them and their associated ancillary equipment in good condition, undertaking regular safety inspections and maintenance.


It is generally accepted that unplanned maintenance can cost up to nine times more than planned maintenance which is why Mono Equipment advocates switching from the more traditionally employed reactive maintenance strategy – which addresses a problem only when it results in unexpected downtime – to a planned preventative maintenance programme.


Mono Equipment highlights some of the key benefits of planned preventative maintenance:


• Increased profitable uptime and reduced costly downtimes: Implementing a planned preventative maintenance programme maintains equipment in optimum working order and helps ensure its continued productivity. The costs associated with having to repair a machine that has broken down can be huge, and it may involve expensive emergency technical call-outs, having to have spare parts priority shipped and can also involve having to pay staff overtime to get the equipment up and running again as soon as possible. In addition to these initial costs, there is also the loss of production which also needs to be taken into account.

fuel. This is said to provide a more streamline solution in production, with quicker install times.


The rack or deck ovens suitable for use with this fuel operate in the same way as a gas oven would, with the key difference being the fuel burned within the burner. The energy produced is still processed through a heat exchanger and into the oven as it would be if using a gas burner, it is just a feed of wood pellets that comes into the burner instead. The use of wood pellets could offer a more sustainable option for those looking to reduce their energy costs and environmental impact.


There are many considerations that need to be taken into account when specifying an oven for a bakery application. While energy efficiency is a vital consideration today, it is important not to ignore other key elements of an oven that will help ensure perfect products day-in, day-out. Most ovens today will offer a host of energy-saving features, in addition to offering a solution to help ensure product consistency, so it should be possible to find a solution that meets your very specific needs and helps save energy into the bargain.


• Reduced risk of complete machine breakdown: Identifying potential issues early on helps ensure that small problems are picked up quickly and do not develop into larger, much more expensive problems which may result in complete machine failure.


• Cost savings by avoiding expensive repairs: A well maintained machine will work more efficiently and effectively and will require less repairs, resulting in an overall decrease in the cost of production. It is also often the case that machines running at peak performance use less energy than those struggling due to technical or mechanical neglect.


• Improved machine and operator safety: Regularly servicing and maintaining machinery


will extend equipment life and will also greatly reduce the risk of harm or injury to operators, helping ensure a safe working environment. Remember that accident-free maintenance is an important criterion in key performance indicator (KPI) targets.


•Prolonged equipment life: A well planned preventative maintenance programme will not only keep a business running as efficiently as possible but will also pay dividends by prolonging the life of equipment and, at the same time, decreasing the need for expensive capital replacements.
