An immersion deep frier including a tank filled to a selected level with shortening and having a plurality of coextensive open-ended heating tubes disposed below such level. Alternate ones of the heating tubes are angled upwardly in one direction and the remaining tubes are angled upwardly in the opposite direction. Burners are disposed at the lower ends of each of the tubes and a blower is provided for forcing air upwardly through the tubes whereby the shortening at the lower ends of the tubes will be heated and caused to expand thereby moving inwardly along the respective tubes to approximately the center of the tank where it will encounter currents moving along the adjacent oppositely angled tubes and will rise upwardly and be turned outwardly to travel to the outer periphery of the tank where it will turn downwardly and inwardly to again commence travel inwardly along the respective tubes thereby providing a number of small currents circulating in the tank to prevent burning of the shortening and provide uniform agitation and circulation of foodstuffs disposed in the tank.
