Convert a Manual Dough Feed to an Auto Feed

Automatically feed dough to the production line and eliminate manual handling

Accurate and consistent dough feeding of the forming system is a major factor in the performance of a snacks production line.

The preferred method of transferring dough is to form a sheet. Snack dough types tend to lack any natural binding forces that allow accurate metering and transfer. Typically, snack dough types need pressure to form a sheet. A pair of sheeting rolls is the optimum method of creating dough pressure and hence a continuous sheet. The advantages of a continuous sheet over randomly discrete pieces are constant feed rate and superior distribution within the forming system hopper.

Account must be taken of the ability of snack dough types to ‘bridge’ or plug. This effect can occur above the sheeting rolls impairing the formation of a uniform dough sheet. A range of anti-bridging systems are available – dough gates to limit build up above the rolls, kibbler shafts that break up dough masses to maintain flow and ‘bridge breakers’ that release dough from the hopper sides.

At Arrow, we use a pair of sheeting rolls with gap adjustment to form a dough sheet. Dough is regulated by a dough gate and a kibbler shaft stops a single mass forming above the rolls.

Use of dough accumulation in the dough feed system frees the mixer to start the next mixing cycle. A conveyor in the bottom of the feed system supported on rollers automatically advances the bulk dough mass. Good design practice is used to avoid the pit falls of dough bridging. Vertical sides lined with low friction material reduce the chance of a dough bridge forming.

Corn masa dough can be likened to machining ‘sand’. You think that you have formed a dough sheet and then one poor transfer can break it. The Arrow dough feeder includes many features to assist transfers such as barbed scrapers that support the dough sheet between roller and conveyor.
