The rotary biscuit machine and biscuit mould should be regularly maintained. A suitable lifting mechanism is required to remove the mould from the rotary biscuit machine. It is recommended to keep it on the mould stand against any impact or damage. It is recommended to store it in a dust-free place at room temperature after cleaning. Washing the mould with hot water just before working on the rotary biscuit machine will cause expansion in the bronze ring and increase wear. Regular control of the bearings is necessary. Finally, the knife and the rubber cylinder should be regularly maintained.
