<p>In order to shorten the duration of a freezing process, thereby reducing the operation cost while at the same time improving quality of a product (22), a freezer (10) for the product (22) is proposed, the freezer (10) comprising:
- a housing (12) having a space (14) therein, and an inlet (16) and an outlet (18) in communication with the space (14);
- a conveyor (20) having a first side for conveying the product (22) through the space (14), and a second side opposite to the first side;
- an agitating apparatus (40) disposed proximate the conveyor (20) for contacting the conveyor (20) at select intervals to agitate the conveyor (20) and displace the product (22) at the first side;
- an, in particular first, longitudinal member (28) disposed proximate the first side of the conveyor (20) and having at least one hole (30) extending therethrough; and
- at least one circulation device (24) disposed in the space (14) proximate the, in particular first, longitudinal member (28) for directing a cryogenic substance (36) through the at least one hole (30) onto the product (22).</p> |
