Method and apparatus for producing fluid ice
A method and an apparatus for producing a fluid ice are provided, wherein temperature and thickness of the fluid ice is independently controllable. The method and apparatus mixes ice together with at least two liquid phases, and stirs the mix. Stirring is maintained until a desired temperature and a desired grain size of the fluid ice is obtained.
1. A method for batch production of fluid ice, comprising:
measuring a salinity of at least two liquid phases;
mixing ice together with the at least two liquid phases; and
stirring the mix together to finely grind the ice,
wherein suitable amounts of said at least two liquid phases and ice are determined based on the salinity and a temperature of the at least two liquid phases to thereby independently control a thickness and a temperature of the fluid ice, and
wherein the stirring is maintained until a desired grain size is obtained and a desired temperature of the fluid ice is stable.
2. The method according to claim 1 , wherein the salinity of the at least two liquid phases is dissimilar.
3. The method according to claim 1 , wherein the at least two liquid phases are introduced prior to the ice.
4. The method according to claim 3 , wherein the ice is introduced in portions.
5. The method according to claim 1 , wherein at least one of the at least two liquid phases comprises at least one compound chosen from flavorants, nutrients, antioxidants, anti-bacterial agents, salts other than sodium chloride sugars, acids, emulsifiers and gelling agents.
6. The method according to claim 1 , wherein the mixing of the ice and the at least two liquid phases is controlled by a computer.
7. An apparatus for producing a fluid ice, comprising:
a drum supported by a supporting frame;
an opening for introducing ice into the drum;
at least one input channel connected to the drum for inflow of at least two liquid phases;
agitating means for agitating the liquid and the ice within the drum;
an output port for emptying the drum; and
a nozzle connected to a pump for pumping the fluid ice out of the drum,
wherein the at least one input channel is provided with a salt meter, a valve and a flowmeter; and
wherein the apparatus is adapted such that a temperature and a thickness of batch-produced fluid ice can be independently controlled by determining suitable amounts of said at least two liquid phases and the ice based on a salinity and a temperature of the at least two liquid phases and thereby independently controlling the thickness and the temperature of the fluid ice.
8. The apparatus according to claim 7 , comprising at least two input channels for inflow of the at least two liquid phases.
9. The apparatus according to claim 7 , wherein the drum is provided with a thermometer for measuring the temperature of the fluid ice.
10. The apparatus of claim 7 , wherein the agitating means comprises a rotatable knife wheel positioned in the bottom of the drum for stirring the ice and the at least two liquid phases, wherein the rotatable knife wheel is fastened on a vertical shaft extending through the bottom of the drum.
11. The apparatus according to claim 7 , wherein the mixing of ice and the at least two liquid phases is controlled with a computer system, wherein the computer system is connected to the agitating means, the salt meters, the valves, the flowmeters and the thermometers.
12. The method according to claim 5 , wherein the antioxidants are chosen from acetic acid, citric acid, vitamin C, BHT, TBHQ, and etoxyquinin.
13. The method according to claim 5 , wherein the salts other than sodium chloride are chosen from phosphates, calcium salts, magnesium salts, and potassium salts.
14. An apparatus for producing a fluid ice, comprising:
a drum supported by a supporting frame;
an opening for introducing ice into the drum;
at least one input channel connected to the drum for inflow of at least two liquid phases;
an agitator to agitate the at least two liquid phases and the ice within the drum;
an output port for emptying the drum; and
a nozzle connected to a pump for pumping the fluid ice out of the drum
wherein the at least one input channel is provided with a salt meter, a valve and a flowmeter; and
wherein the apparatus is adapted such that a temperature and a thickness of batch-produced fluid ice can be independently controlled by determining suitable amounts of said at least two liquid phases and the ice based on a salinity and a temperature of the liquid phases and thereby independently controlling the thickness and the temperature of the fluid ice.
15. The apparatus of claim 14 , wherein the agitator comprises a rotatable knife wheel positioned in the bottom of the drum for stirring the ice and the at least two liquid phases, wherein the rotatable knife wheel is fastened on a vertical shaft extending through the bottom of the drum.
16. A drum for producing a fluid ices comprising:
an opening for introducing ice into the drum;
at least one input channel connected to the drum for inflow of at least two liquid phases;
an agitator to agitate the at least two liquid phases and the ice within the drum;
an output port for emptying the drum; and
a nozzle
wherein the at least one input channel is provided with a salt meter, a valve and a flowmeter.
