A fried potato product e.g. crisps or sticks is made from peeled, sliced potatoes by firstly frying in oil to a moisture content of 5-20% by weight, then frying in oil under reduced pressure at a temperature not exceeding 100‹C. to give a product having a moisture content of less than 2.5%. The crisps are prepared in an oven having a closed housing 1 with at least one supply sluice 6 and at least one discharge sluice 7, a suction pipe 2 connected to a pump 5 for sucking off water vapour and maintaining reduced pressure; a belt conveyer 8 for carrying cuttings through the oil for cooking, a conveyer 27 obliquely inclined for removing cuttings from the oil, a vibrating frame 31, and means for supplying, discharging and circulating the oil. The supply and discharge sluices preferably have boxes 36 which house lids (37) that can be moved to seal the entrance and exit to the oven. |
