Patent ID: 7024799

Claim:
Process for treating products (P) with air treated by a thermodynamic treatment machine, comprising the steps of: a) calculating, for a treatment objective, the operating regime of the thermodynamic treatment machine defined by an assembly of predetermined operating parameter values, comprising: the operating condition of power driven fans ( 7 , 11 ) driving the air to be treated through the treatment machine; the opening position condition of registers ( 13 – 16 ; 9 ) for access of the air to be treated by the treatment machine; the operating condition of the compressor or compressors of the treatment machine; the switching condition of a reversing valve reversing the operation of the thermodynamic treatment machine; the quantity of products (P) to be treated; a theoretical quantity of water (Qtheo) to be extracted per unit time, said theoretical quantity (Qtheo) being determined by: the nature of the products (P) to be treated; the desired duration of treatment, the treatment objective predetermined by a combination of at least: a quality treatment criterion measured on the products; (P) a duration of treatment; a consumption of electricity by the treatment machine; an economical cost; b) loading into a receptacle, at least partially closed ( 20 ), a load of products (P) to be treated; c) removing, at most, a fraction of the air from the load of products (P), and making a determination concerning mixing with external air; d) controlling the flow rate, the temperature and/or the quantity of moisture saturating the treated air so as to produce a treated airflow, such that there will be applied a treatment of dehumidification, humidification, heating and/or cooling of the treatment air; and e) reinjecting at least a portion of the treated airflow into the load (P); and f) applying the treatment steps c)–e) until said treatment objective is achieved for said assembly of predetermined values of the operating parameters.
