Apparatus for cooling high-heat-treated food products, method for performing this, and heat-treatment line for this

1. An apparatus for cooling high-heat-treated food products with a flash cooler, having a container for a pre-product to be cooled with an inlet for the pre-product to be cooled and an outlet for a cooled end product of the food product as well as cooling equipment, wherein

said apparatus is adapted for continuous cooling of high-heat-treated food products,

the container having a bowl having the outlet for the cooled end product of the food product and a lid, to which the inlet of the pre-product to be cooled is associated,

wherein the cooling equipment is associated both to the bowl and the lid,

the cooling equipment has a cooling jacket associated to the container through which jacket at least one part of a wall of the container is cooled,

the cooling jacket is located or formed on the bowl and on the lid of the container,

wherein a longitudinal axis of the container is positioned at an acute angle (α) with the vertical such that the bowl provides for the lowest part of the container, and said outlet for the cooled end product of the food product is located a position lower than the center of the bowl, and

wherein the cooling equipment is configured to cool the pre-product and steam generated by the pre-product.

2. The apparatus according to claim 1 , the cooling jacket being formed by a double wall of at least one part or on at least one part of the container or pillow plate.

3. The apparatus according to claim 1 , wherein the cooling jacket contains at least two separately operable cooling zones.

4. The apparatus according to claim 1 , wherein a creaming apparatus is located in the container.

5. A heat-treatment line for food products, containing the apparatus according to claim 1 .

6. The heat-treatment line for food products according to claim 5 , which is a continuous heat-treatment line.

7. A method for cooling high-heat-treated, particularly ultra-high-heat-treated food products, with a flash cooler, having a container for a pre-product to be cooled, with an inlet for the pre-product to be cooled and an outlet for a cooled end product of the food product as well as cooling equipment, wherein liquid evaporates from the pre-product and the heat is removed by condensation on an inner wall of the container,

continuously cooling high-heat-treated food products with the flash cooler,

providing the container with a bowl having the outlet for the cooled end product of the food product and a lid, to which the inlet of the pre-product to be cooled is associated,

providing the cooling equipment associated both to the bowl and the lid, the cooling equipment having a cooling jacket associated to the container through which jacket at least one part of a wall of the container is cooled, the cooling jacket located or formed on the bowl and on the lid of the container, and

positioning a longitudinal axis of the container at an acute angle (α) with the vertical such that the bowl provides for the lowest part of the container, and said outlet for the cooled end product of the food product is located at a position lower than the center of the bowl, and

cooling the pre-product and steam generated by the pre-product.

8. The method according to claim 7 , wherein the cooling jacket contains at least two separately operable cooling zones.

9. The method according to claim 7 , wherein a creaming apparatus is located in the container.
