Tsubaki conveyor chain leads to long term cost savings and efficiency for commercial bakery Producing high quality, consistent baked goods in a batch production requires precise and reliable processes and equipment. For one bakery, the industrial oven it used for producing pre-baked bread rolls required new conveyor chain every two years due to excessive wear. This was an expensive and time-consuming operation that affected the bakery’s production targets. Fortunately, Tsubaki’s expert engineers were able to recommend a specialised chain product that more than doubled service life. Almost every village in France still has its own boulangerie, a bakery handed down through the generations of a family of master craftsmen. Today, their bakers combine tradition with Photo Caption: Tsubaki suggested that the bakery lubricate the chain with a specialty food-grade lubrication formulated to be stable in very high temperatures.
