摘要： An adjustable continuous filtration system for cooking fats and cooling oils. Using a variable orifice restriction such as a valve, the amount of cooking fat or cooking oil recycled to a filter is controlled in accordance with the results of testing the discharged cooking fat or cooking oil for quality control, by changing the size of the orifice. If the discharged fat or oil not within industry standards, the proportion being recycled is increased. If the fat or oil tests appreciably above industry standards, the proportion recycled to the filter is decreased.

摘要： Apparatus and method for determining the percentage of free fatty acids in cooking fats and oils. A kit for this analysis includes a test cylinder calibrated for (a) volume of test sample, (b) volume of acid-base indicator solution, and (c) a set of lines marked to be read directly as the percentage of free fatty acids in the sample.
