[Also in Divisions A4 and F4] Surface water is removed from water impregnated morsels of food before the morsels are dehydrated in hot oil, wherein the morsels are passed downwards through a bath of cold oil to cause the surface water to separate from the morsels, said water being removed from the bottom of the bath. The morsels thus treated are then passed to a cooking apparatus which comprises an upwardly extending dehydration section having a bottom inlet for the treated morsels and connecting at its top end with a cooking section, the dehydration section being provided with hot oil at a temperature such that water in the morsels is turned into steam, the morsels and the steam rising in the dehydration section to enter the cooking section where heat from the steam is used to cook the morsels. The process may be carried out in the apparatus shown in Fig. 1 wherein water-impregnated morsels of food are passed through cold oil in section 10 to remove surface water which is drained off through the well 16. Oil, heated at the heat exchanger 25 is injected via 18 to the dehydration section 13 up which the treated morsels are passed from section 10. After dehydration, the morsels are passed into cooking section 14 which includes a spiral elevator 28 which is given a high-frequency, low amplitude oscillation about its vertical axis via the mechanism in housing 29. The spiral flight of the elevator 28 co-operates with the spiral wall vane 30 to slow down the rise of the steam through the section 14. The top of the elevator flight extends through a side outlet 31 for removal of the cooked morsels. The morsels are preferably of potato.
