Functional continuous rapid freezing apparatus
View Patent ↗To provide a functional continuous rapid freezing apparatus with which cold air is made uniformly contact with the whole face of an article to be frozen, easily and rapidly passing the maximum ice crystal generating zone, and the central portion of the article to be frozen can reach for the predetermined temperature within a short period of time, a freezing chamber 2 in which an article Q to be frozen is stored, a heat exchanger 1 for cooling disposed on a central portion of the freezing chamber 2 as a partition to divide the freezing chamber 2 into a first freezing block 2 a and a second freezing block 2 b , a first blowing fan 5 disposed to face the heat exchanger 1 for cooling through the first freezing block 2 a , and a second blowing fan 6 disposed to face the heat exchanger 1 for cooling through the second freezing block 2 b , are provided.
1. A functional continuous rapid freezing apparatus characterized by that a freezing chamber ( 2 ) in which an article (Q) to be frozen is stored, a heat exchanger ( 1 ) for cooling disposed on a central portion of the freezing chamber ( 2 ) as a partition to divide the freezing chamber ( 2 ) into a first freezing block ( 2 a ) and a second freezing block ( 2 b ), a first blowing fan ( 5 ) disposed to face the heat exchanger ( 1 ) for cooling through the first freezing block ( 2 a ), and a second blowing fan ( 6 ) disposed to face the heat exchanger ( 1 ) for cooling through the second freezing block ( 2 b ), are provided,
wherein a fan controlling portion ( 8 ), which controls fan rotating directions of the first blowing fan ( 5 ) and the second blowing fan ( 6 ) as to switch cold air in the freezing chamber ( 2 ) generated by the heat exchanger ( 1 ) for cooling to a flowing from the first freezing block ( 2 a ) to the second freezing block ( 2 b ) and to a flowing from the second freezing block ( 2 b ) to the first freezing block ( 2 a ) for a predetermined time, is provided.
