In the soda cracker production, just after the baking, the products are usually sprayed with oil to enhance their taste and to give a glossing appearance.
The unit designed by Imaforni consists of a set of spinning disks which rotate at a fixed speed. A pump system sprays the oils through a nozzle against the surface of the spinning disk. Specially designed adjustable guides ensure that the oil is uniformly distributed across the width of the conveyor.
It is equipped with two independent systems, one positioned on top, the other at the bottom of the wire mesh conveyor. The operator is thus easily able to regulate the amount of oil for top and bottom.
The oil is contained in a small jacketed and heated buffer tank located in the frame of the machine, while a re-circulating adjustable pump conveys the oil to the nozzles. The excess oil which is not taken by the product is collected back in the same bin. Two easily replaceable fine-grade filters collect any debris or crumbs. The unit is fully constructed in AISI 316 stainless steel while the shape and the special design of the edges of the hood ensures that the oil mist does not escape from the machine, leaving a clean space around the unit – a solution much appreciated by all experienced production managers. The machine as a whole is mounted on wheels so that it can easily be moved to the washing room.
Our Technical Department has designed this equipment in order to provide even and uniform oil distribution across the entire width, from the beginning to the end of the production shift.
In our experience, working widths of up to 1700 mm are generally used for fast cracker lines of up to 40 m/min.
