The apparatus further comprises a cover (6) which forms with the receptacle (4) substantially closed chamber during heating. The axis may form an adjustable first angle with a vertical line. The apparatus further comprises a roof (6) which may rotate relatively with regard to the recipient (4) over a second angle which is smaller than 60.degree. to allow for filling or emptying the heating apparatus with articles of food. The heating apparatus may be used for substantially all articles of food which may be heated and the apparatus has a good thermal efficiency.
