Abstract

This invention relates to a quick-freezing equipment, cabinet type, with discontinuous operation, using the method of freezing by contact with liquid nitrogen, in order to reduce the temperature of the products to the temperature of storage in a frozen state. The multifunctional quick-freezing equipment consists of a support frame (S), a double thermal insulated enclosure (IE), a tray rack (TR), a tray rack drive system (DS), a mechanical vapour ventilation plant (MV), a liquid nitrogen supply plant (NS), a mechanical vapour compression freezing refrigeration plant (CP), a Dewar vessel (DV) with purge head and respectively an automation plant (AP). The double thermal insulated enclosure (IE) is made in the form of a construction made up of two enclosures separated by a common wall and allows the reuse of nitrogen vapours that have not yet been used at maximum efficiency in the quick-freezing room (2) for additional cooling the adjacent room (3). The tray rack drive system (DS) and a liquid nitrogen supply plant (NS) are configured to, through a synergistic action, purge liquid nitrogen with high precision and flat distribution on the target surface and to homogenize the exposure to the liquid nitrogen jets. The automation plant (AP) is configured both to avoid the entrainment of liquid nitrogen particles and the deviation of their trajectory towards the side walls of the enclosure, and to quickly pass the phase of maximum crystallization of the aqueous solution contained in the product.
