Abstract
A process of freezing a belt of encapsulated ice substitute is provided. The process for freezing the ice substitute belt generally includes the steps of preparing a capsule belt with a plurality of capsules, each capsule containing a thermal controlling agent which is a liquid in a predetermined temperature range; preparing a brine including a cruciferous oil, salts and a glycol and cooling the brine; feeding the belt into an apparatus which contains the cooled brine and passing the belt through the brine; adjusting the speed to the extent sufficient for the thermal controlling agent to become solidified. The travelling speed of the ice substitute belt is adjusted depending on the composition of the thermal controlling agent.
Claims21
An apparatus for freezing a belt of encapsulated ice substitute, comprising
- a tank for containing a brine including an oil, salts and a glycol, said tank having an inlet side and an outlet side for permitting said ice substitute belt entry into and exiting from said tank,
- means for guiding said ice substitute belt into, through and out of said brine in said tank, said guiding means including a downwardly arcuate bottom guide disposed in said tank and extending from said inlet side to said outlet side through said tank for guiding said ice substitute belt through said brine in said tank,
- a roller rotatably mounted relative to said tank and above and closely spaced from said bottom guide at a location where said bottom guide is immersed in said brine in said tank for contacting and advancing said ice substitute belt on said bottom guide, said roller being connectable to a motor means for rotatably driving said roller, and
- means for cooling said brine to a temperature between about -22.degree. and about -43.6.degree. F.
A process for freezing a belt of encapsulated ice substitute containing a thermal controlling agent which is a liquid having a freezing point within a predetermined temperature range in a brine including a cruciferous oil, a salt and a glycol, comprising the steps of:
- a) cooling said brine to a temperature between about -22.degree. and -43.6.degree. F.;
- b) introducing said belt of encapsulated ice substitute into said cooled brine;
- c) moving said ice substitute belt through said cooled brine by a rotating a roller engaging said belt until said thermal controlling agent forms a solid phase;
- d) then removing said ice substitute belt with the solid phase thermal controlling agent from said tank.
