The method comprises capturing mineral oil, flour, and dough contaminants which becomes mixed as the dough divider operates and filtering the captured mixture so that substantially pure mineral oil is separated from the flour, dough and contaminates. The substantially pure mineral oil is then injected back into the dough divider machine for lubrication. By comparing lost mineral oil to the weight of bakery products produced during a predetermined period, the amount of mineral oil in the bakery products is determined. The filtration method and device utilize a gravity filtration diffuser coalesence and precipitation and a suction filtration. The device is portable for use with either one or more dough divider machines and for cleaning.Field of SearchAnd recirculating liquidWITH ALARM, INDICATOR, REGISTER, RECORDER, SIGNAL OR INSPECTION MEANS Plural separating Including controlling process in response to a sensed condition Closed circulating systems Lubrication Machinery Serially connected distinct treating or storage units Of filtrate WITH MOVABLE SUPPORT WITH DRIP, OVERFLOW OR CONTENT DRAINING FEATURE Alternate filters and traps in series Baffle preceding or within sediment trap Deflecting prefilt from filter medium Downstream of filter medium Downflow inlet, upflow through filter medium Sediment discharge means | |
