Problems solved by technology

[0009] Exposing the compressor to extremely hot heat exchanger fluid significantly reduces the operating life of the compressor (affecting both mechanical and electrical components, including compressor oil)
[0010] In fact, during the operation of the system, the temperature inside the compressor increases, sometimes quite high, to 130°C and above, causing rapid wear and shortening of the working life of the components, especially the motor and oil

Abstract

A thermodynamic system for cooling or heating at least a first container (22) containing a food product of liquid or semi-liquid type, comprising a circuit employing a heat exchanger fluid, and having at least: - a compressor (2) with at least one inlet (I) for said heat exchanger fluid and one outlet (U) for said heat exchanger fluid; - a first heat exchange connected to the outlet (U) of said compressor (2) device (3); - at least one first expansion element (4a) connected to the outlet of said first heat exchanger (3); - a second heat exchanger (5a), which can be connected to said first container ( 22) associated and having an inlet (5a') connected to the outlet of said at least one first expansion element (4a); - a return duct (6) having an outlet connected to the second heat exchanger (5a) An inlet section (6') and an outlet section connected to the inlet (I) of the compressor (2).

Description

technical field [0001] The present invention is devoted to the field of machines for the manufacture of liquid or semi-liquid foods. [0002] More particularly, the present invention relates to thermodynamic systems, machines for the manufacture of liquid and semi-liquid products, and heat treatment methods comprising the same. Background technique [0003] In the field of machines for the manufacture of liquid and semi-liquid products such as ice cream, cake and pastry fillings, etc., it is standard practice to heat treat the product (by heating and / or cooling) to prepare a predetermined recipe. [0004] Various thermodynamic types of thermal systems are known in the prior art, which allow the thermal treatment (heating or cooling) of a product in a container to alter its food / sensory properties. [0005] Most thermodynamic systems for cooling are based on the inverse Carnot cycle (also known as the saturated vapor compression cycle): these systems allow the vessel to be c...
