Abstract

A method for providing a heat treated liquid product is provided. The method comprises the steps of heating a flow of liquid product; providing an ice slurry of sterile water being separated from said flow of liquid product; and combining said flow of liquid product with said ice slurry for cooling down the flow of liquid product.

First claim

1 . A method for providing a heat treated liquid product, comprising:
heating a flow of liquid product; providing an ice slurry of sterile water being separated from said flow of liquid product; and combining said flow of liquid product with said ice slurry for cooling down the flow of liquid product.

2 . The method of claim 1 , further comprising keeping the flow of liquid product at an elevated temperature for a predetermined time before the step of combining said flow of liquid product with said ice slurry.

3 . The method of claim 1 , further comprising providing said flow of liquid product as a flow of a liquid product concentrate.

4 . The method according to claim 1 , wherein the combining of said flow of liquid product with said ice slurry is performed such that the ratio between the amount of liquid product and the amount of sterile water ice slurry is between 10:1 and 20:1.

5 . The method according to claim 1 , wherein the temperature of the mix of liquid product and sterile water ice slurry is between 30 and 50° C.

6 . The method according to claim 1 , wherein the step of providing said sterile water ice slurry is performed by the steps of:
pumping water through a sterile filter, and transporting said sterile water through a hygienic freezing cylinder.

7 . The method according to claim 1 , wherein the step of providing said sterile water ice slurry is performed by the steps of:
sterilize water by heating, and transporting said sterile water through a hygienic freezing cylinder.

8 . The method according to claim 1 , wherein said liquid product is a liquid food product.

9 . A combiner, comprising
a first inlet for receiving a heated liquid product,
a second inlet for receiving a sterile water ice slurry,
a combining chamber for cooling down said heated concentrate by combining said heated liquid product with said sterile water ice slurry, thereby also forming a heat treated liquid product, and
an outlet for outputting said heat treated liquid product.

10 . The combiner according to claim 9 , further comprising a controller configured to control operating parameters of the combiner such that said operating parameters may be adjusted in accordance with predetermined parameters for the specific liquid product.

11 . A system for providing a heat treated liquid product, comprising
at least one heater for increasing the temperature of a liquid product flowing through said heater; a supply of sterile water ice slurry; and a combiner according to claim 9 .

12 . A liquid food product, manufactured by the method according to claim 1 .

13 . A method for providing a heat-treated liquid product, the method comprising:
heating a liquid product concentrate to a pasteurization temperature or a sterilization temperature sufficient to prevent growth of micro-organisms to produce a heated liquid product concentrate; introducing the heated liquid product concentrate into a combiner; introducing an ice slurry of sterile water into the combiner, the ice slurry of sterile water being separate from the heated liquid product concentrate before introduction into the combiner, the ice slurry introduced into the combiner possessing a temperature lower than the temperature of the heated liquid product introduced into the combiner; and the introduction of the heated liquid product concentrate into the combiner and the introduction of the ice slurry of sterile water into the combiner causing the heated liquid product concentrate and the ice slurry of sterile water to be combined and to increase a water content of the heated liquid product concentrate while also decreasing the temperature of the heated liquid product to produce the heat-treated liquid product which is at a lower temperature than the heated liquid product concentrate and which possesses a lower concentration than the heated liquid product concentrate.

14 . The method according to claim 13 , wherein the introduction of the ice slurry of sterile water and the introduction of the heated liquid product concentrate into the combiner is performed by introducing a relatively greater amount of the heated liquid product concentrate into the combiner and a relatively lesser amount of the ice slurry of sterile water into the combiner.

15 . The method according to claim 13 , wherein the introduction of the ice slurry of sterile water and the introduction of the heated liquid product concentrate into the combiner is performed such that a ratio between an amount of the heated liquid product concentrate and an amount of the ice slurry of sterile water is between 10:1 and 20:1.

16 . The method according to claim 13 , wherein the temperature of the heated liquid product concentrate and the ice slurry of sterile water is between 30 and 50° C.

17 . The method according to claim 13 , further comprising pumping water through a sterile filter to produce sterile water, and transporting the sterile water through a hygienic freezing cylinder to produce the ice slurry of sterile water that is introduced into the combiner.

18 . The method according to claim 13 , further comprising sterilizing water by heating to produce sterile water, and transporting the sterile water through a hygienic freezing cylinder to produce the ice slurry of sterile water that is introduced into the combiner.
