A method for coating food products with a coating substance, comprising: - a step a) of supercooling the food products, by providing external frigories, to a temperature lower than the initial temperature of same, before contacting the food products with the coating substance, and subsequently - a step b) of contacting the supercooled food products obtained in step a) with the coating substance, the coating around the products being formed at this step by the freezing of said coating substance under only the action of the transfer of frigories from the food products to the coating substance, in other words without providing external frigories, characterised in that in step b): - the supercooled food products are contacted with the coating substance in a treatment chamber , - the food products are stirred by means of a motorised mechanised system, comprising at least one stirring member, internal to said treatment chamber , movable with respect to said treatment chamber , - said at least one stirring member is heated, and the intensity of the heating is adjusted without excess heating, so that the distribution of the coating substance around the food products is made uniform and/or to avoid the accumulation of material on said stirring member, while ensuring the coating around the food products by the freezing of the coating substance under the action of the transfer of frigories from the food products to the coating substance. - a step a) of supercooling the food products, by providing external frigories, to a temperature lower than the initial temperature of same, before contacting the food products with the coating substance, and subsequently - a step b) of contacting the supercooled food products obtained in step a) with the coating substance, the coating around the products being formed at this step by the freezing of said coating substance under only the action of the transfer of frigories from the food products to the coating substance, in other words without providing external frigories, characterised in that in step b): - the supercooled food products are contacted with the coating substance in a treatment chamber , - the food products are stirred by means of a motorised mechanised system, comprising at least one stirring member, internal to said treatment chamber , movable with respect to said treatment chamber , - said at least one stirring member is heated, and the intensity of the heating is adjusted without excess heating, so that the distribution of the coating substance around the food products is made uniform and/or to avoid the accumulation of material on said stirring member, while ensuring the coating around the food products by the freezing of the coating substance under the action of the transfer of frigories from the food products to the coating substance. - the supercooled food products are contacted with the coating substance in a treatment chamber , - the food products are stirred by means of a motorised mechanised system, comprising at least one stirring member, internal to said treatment chamber , movable with respect to said treatment chamber , - said at least one stirring member is heated, and the intensity of the heating is adjusted without excess heating, so that the distribution of the coating substance around the food products is made uniform and/or to avoid the accumulation of material on said stirring member, while ensuring the coating around the food products by the freezing of the coating substance under the action of the transfer of frigories from the food products to the coating substance. <EOS>
