The apparatus for preparing and dispensing food products comprises at least one containment tank (2) predisposed to contain the product to be prepared. Inside the containment tank (2) a mixing device (3) is arranged for determining the continuous circulation of the product. The apparatus comprises temperature control means (9) and product consistency control means (30) for controlling the consistency of the product being prepared. The product consistency control means (30) comprise a first microswitch (31) and a second microswitch (32) predisposed to be selectively operated when a first threshold value and a second threshold value of resistance against elastic means (22) acting on the mixing device (3) are exceeded, in order to control the stop of cooling or heating means (4) of the product contained within the tank (2).
