Rotary moulder is used for soft dough and soft variety of biscuits. The dough to be moulded is fed into the hopper and a forcing roller forces the dough into the cavities of the moulding roller made out of gun metal, uniformly engraved and coated with food grade Teflon. Excess dough is cleared with a knife, which is held by a holder made from tool steel, to ensure uniform filling.
An adjustable rubber roller conveying the discharge cotton web, presses it uniformly against the moulding roller for perfect transfer of molded pieces from the moulding roller on to the web.
The purpose of three drives is, speed of the forcing roller influences the density of dough forced in to the moulding cavity. The speed of the die roller influences the production speed. The discharge web speed influences the shape of the biscuits produced along the web or across the web.
