PURPOSE:To reduce the size and power cost for the preparation of frozen food and to obtain a frozen food of loosened state at a low cost, by supplying a cooling gas from the lower part to the upper part of a cylindrical apparatus having plural partition sections and successively transferring a food from the partition section of upper state to that of lower stage. CONSTITUTION:Chilled gas for cooling is passed upward through a cylindrical apparatus 21 having plural partition sections 22a-22d vertically divided with gas-permeable trays 22. Separately, granules or small pieces of a food A to be cooled are supplied from the upper feeding port 29 of the cylindrical apparatus 21 and successively and intermittently transferred to the lower partition sections 22a-22d. If necessary, the food is agitated in each partition section. The frozen food is taken out of the cylindrical apparatus through the lower delivery port 30.
