Abstract

The method for preparing refrigerated products provides to control the solidity of a product being prepared inside a containment tank (2) of said product, until reaching a predetermined solidity, and to measure the temperature of the same product inside said tank (2) once reached said predetermined solidity. Once reached the predetermined solidity, said temperature of the product is set as reference temperature and said reference temperature is kept constant during the subsequent functioning.

Claims

1. A method for preparing refrigerated products, in an apparatus comprising at least one containment tank predisposed to contain a product to be prepared, a mixing device arranged inside said tank and predisposed to determine a continuous circulation of said product inside said tank, for conveying said product towards a front zone of said tank, a cooling device arranged inside said tank to cool said product, and a dispensing device of said product, placed at said front zone of said containment tank, the method comprising the steps of:

controlling a solidity of said product being prepared inside said tank such that said solidity of said product has a predetermined solidity;

upon reaching said predetermined solidity, measuring a temperature of said product inside said tank;

setting said temperature of said product upon reaching said predetermined solidity as a reference temperature;

controlling said temperature of said product inside said tank to preserve said reference temperature during subsequent working of said apparatus;

automatically repeating, in case of temperature variation inside said tank beyond a prefixed limit, a cycle comprising a preparation step to bring said product at said predetermined solidity, a stabilization step of said predetermined solidity followed by measuring said reference temperature and a preserving step of said reference temperature through a constant control of said temperature of said product.

2. A method according to claim 1, wherein said solidity of said product being prepared is controlled through a resisting torque met by a screw element of said mixing device brought in rotation inside said tank.

3. A method according to claim 1, further comprising:

stabilizing said solidity of said product at said reference temperature by means of a series of cycles of switching on and off of said cooling device.

4. A method according to claim 2, further comprising:

stabilizing said solidity of said product at said reference temperature by means of a series of cycles of switching on and off of said cooling device.
