Device for freezing and/or cooling-down products

Abstract

The invention relates to a device for freezing and/or cooling-down products comprising a cooling chamber ( 1 ), which encompasses a transport device ( 2 ) for conveying the products ( 6 ) through the cooling chamber ( 1 ), at least one device ( 3 ) for generating a cold gas atmosphere for the cooling chamber ( 1 ) and an extraction device ( 7 ) for the cold gas as well as at least one axially conveying ventilator ( 4 ) for conveying the cold gas, characterized in that the axis ( 5 ) of the at least one ventilator ( 4 ) is attached at an angle to the vertical, wherein the vertical to the moving direction of the products ( 6 ) serves as reference direction and the at least one ventilator ( 4 ) is attached to the ceiling of the cooling chamber ( 1 ), wherein the axis ( 5 ) of the ventilator ( 4 ) includes an angle b with a vector, which represents the moving direction of the products ( 6 ), wherein the origin of the vector is placed at the lower end of the axis ( 5 ). The invention furthermore relates to a use of the device

1 . A device for freezing and/or cooling-down products comprising a cooling chamber ( 1 ), which encompasses a transport device ( 2 ) for conveying the products ( 6 ) through the cooling chamber ( 1 ), at least one device ( 3 ) for generating a cold gas atmosphere for the cooling chamber ( 1 ) and an extraction device ( 7 ) for the cold gas as well as at least one axially conveying ventilator ( 4 ) for conveying the cold gas, characterized in that the axis ( 5 ) of the at least one ventilator ( 4 ) is attached at an angle to the vertical, wherein the vertical to the moving direction of the products ( 6 ) serves as reference direction and the at least one ventilator ( 4 ) is attached to the ceiling of the cooling chamber ( 1 ), wherein the axis ( 5 ) of the ventilator ( 4 ) includes an angle b with a vector, which represents the moving direction of the products ( 6 ), wherein the origin of the vector is placed at the lower end of the axis ( 5 ). 
     
     
         2 . The device according to  claim 1 , characterized in that the angle b between the axis ( 5 ) and the vector is smaller than 90°, thus acute angled. 
     
     
         3 . The device according to  claim 1 , characterized in that the angle b between the axis ( 5 ) and the vector is greater than 90°, thus obtuse angled. 
     
     
         4 . The device according to one of  claims 1  to  3 , characterized in that the angle a, which the axis ( 5 ) of the ventilator ( 4 ) draws with the vertical, lies in the range of from 1° to 8°, preferably in the range of from 1° to 5°. 
     
     
         5 . The device according to one of  claims 1  to  4 , characterized in that provision is made for a device for injecting cold gas. 
     
     
         6 . The device according to one of  claims 1  to  5 , characterized in that provision is made for a cold gas reservoir, in particular for a cold gas reservoir for liquefied cold gas. 
     
     
         7 . The device according to one of  claims 1  to  6 , characterized in that provision is made for liquid nitrogen and/or liquid carbon dioxide for generating the cold gas. 
     
     
         8 . A use of the device according to one of  claims 1  to  7  for freezing and/or cooling-down foods.
