Claim Text:
1. A machine for making and dispensing at least one chosen from semiliquid and semisolid food products comprising: a working unit equipped with a processing cylinder for processing a mixture of a basic product and air into the food products, a heat exchange fluid flow chamber located around the processing cylinder, a dispensing tap for dispensing the food products from the processing cylinder, a system for treating and feeding heat exchange fluid to the flow chamber; a flexible container for containing the basic product; a supply duct for supplying the mixture of basic product and air to the processing cylinder, a peristaltic pump connected to the supply duct and configured to transfer the basic product from the container to the processing cylinder, a control and drive unit; a first pressure sensor located along the supply duct downstream of the peristaltic pump for detecting a first pressure at which the mixture is fed into the processing cylinder and sending to the control and drive unit a first signal indicating the first pressure; the control and drive unit programmed to send at least one output signal for adjusting the peristaltic pump; a mechanism for generating a flow of air under pressure flowingly connected to an infeed end of the peristaltic pump to add air to the basic product to form the mixture of basic product and air; the control and drive unit being programmed to determine whether the first pressure is outside a predetermined range, and if so:
