The rotary moulder is specially designed for the production of soft biscuits. By flexibly replacing the mould, it can imprint exquisite patterns, designs or brand logos on the surface of biscuits. The rotary moulder cooperates with the feeding roller, mould and rubber roller to precisely control the pressure and accuracy, ensuring that the pattern on each biscuit is clear and the weight is uniform. The rotary moulder can be used as an independent forming device, and it can also be conveniently integrated into a multifunctional production line to finish flexible switching. The rotary moulder can be equipped with milk wash, salt sprinkler, etc. to make the products more diversified, or it can directly connect with the baking section.
