The method of the present invention is directed to freezing of a substance such as to instantly freeze consumable fluids and food without altering their chemical compositions. The instant freezer apparatus generally comprises a main frame and a removable freezing module. The apparatus may further comprise a freezing fluid injection system such as a liquid carbon dioxide tank or a liquid nitrogen tank fluidly connected to the main frame. At least two freezing cells comprising the fluid to be frozen may be included, the freezing cells being independently removable from the freezing module and other freezing cells. A semi-flexible mat for receiving and supporting varying shapes of freezing cells may be included. ## Claims ### Claim 1 A method to expedite freezing of a substance, the method comprising: pouring the substance in a recess portion of a removable individual freezing cell in fluid communication with a freezing chamber, the removable individual freezing cell being separate of the freezing chamber and the recess portion being accessible to the user during freezing operations; injecting a volume of freezing fluid in the freezing chamber toward the removable individual freezing cell during a determined period of time; exiting the freezing fluid from the freezing chamber; removing the removable individual freezing cell from the freezing chamber; removing the frozen substance from the removable individual freezing cell. ### Claim 2 (depends on 1) The method of claim 1, the method further comprising removing the freezing cell prior to removing the frozen substance. ### Claim 3 (depends on 1) The method of claim 1, wherein the removing of the individual removable freezing cell comprises handling the individual removable freezing cell. ### Claim 4 (depends on 1) The method of claim 1, wherein the removing of the individual freezing cell is performed using a handle. ### Claim 5 (depends on 1) The method of claim 1, the injection of freezing fluid being executed with at least one injector adapted to project frozen fluid toward the removable individual freezing cell. ### Claim 6 (depends on 1) The method of claim 1, the injection of the frozen fluid further comprising respectively aligning at plurality of the removable individual freezing cells with at least one injector, each injector being adapted to project frozen fluid toward each of the removable individual freezing cells. ### Claim 7 (depends on 1) The method of claim 1, the method further comprising automatically controlling debit of the injected freezing fluid to maintain a desired temperature inside the freezing chamber. ### Claim 8 (depends on 1) The method of claim 1, the method further comprising stopping injection of the freezing fluid. ### Claim 9 (depends on 1) The method of claim 1, wherein the removable individual freezing cell comprises a surface opposite to the at least one recess portion. ### Claim 10 (depends on 1) The method of claim 1, the method further comprising covering the removable individual freezing cell prior to the injection of the freezing fluid. ### Claim 11 (depends on 10) The method of claim 10, the method further comprising locking a cover to the freezing chamber to cover the removable individual freezing cell. ### Claim 12 (depends on 9) The method of claim 9, the method further comprising inserting a plurality of the removable individual freezing cells into a plurality of recess portions over the freezing chamber. ### Claim 13 (depends on 12) The method of claim 12 further comprising, positioning the surface opposite to the recess portion of the removable individual freezing cell to be in fluid communication with the freezing chamber.
