A rapid-freezing apparatus, comprising a refrigeration chamber accomodating a conveying mechanism for partly prepared and ready-made food products to be frozen, a fan and an air cooler. According to the invention, the conveying mechanism for partly prepared and ready-made food products is a multi-level conveyer comprising two vertical rotatable supports which drive a flexible traction member. Around the flexible traction member is mounted a helical monorail of the conveyer. Bearing upon the monorail are screen trays for products to be frozen, provided with rollers and attached to the flexible traction member by clamps.
