Abstract
Abstract This invention relates to incorporating a gas into a hot candy (sugar) melt within a pressure vessel at superatmospheric pressure. The gasified hot melt is transferred from the pressure vessel to a cooling tube, through a line or lines connecting the bottom of the pressure vessel to the bottom of the tube, by creating pressure differential between the cooling tube and the pressure vessel while venting the top of the tube to the atmosphere. When the transfer is complete, the cooling tube is isolated and the pressure within it is maintained at superatmospheric and it is cooled to a temperature below 70°F. whereby the gasified hot melt becomes a gas-containing solid matrix. Next, the cooling tube is shock-treated so that the gas-containing solid matrix is shattered into multiple fragments.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
231 words
A method of making a carbonated candy which comprises: a. obtaining a hot candy melt, b. introducing the hot melt into a first pressure vessel, c. introducing a gas at superatmospheric pressure into the first pressure vessel so that the gas is dispersed within the hot melt, d. introducing a gas at superatmospheric pressure into a second pressure vessel at a value equivalent to the pressure within the first pressure vessel, the first and second pressure vessels having a connecting line with valve means between the bottom of the first vessel and the bottom of the second vessel, e. transferring the gasified hot melt to the second pressure vessel through the connecting line by opening said valve means and then creating a pressure differential between the two vessels, said differential being effected by regulating the superatmospheric pressure in the second pressure vessel at a value lower than the superatmospheric pressure in the first pressure vessel and venting the top of the second pressure vessel, f. isolating the second pressure vessel while continuing to maintain a superatmospheric pressure, g. cooling the second pressure vessel so that the gasified hot melt becomes a gas-containing solid matrix, h. shock-treating the second pressure vessel so that the gas-containing solid matrix is shattered into multiple fragments, i. venting the second pressure vessel, and j. opening the second pressure vessel to allow the product to be removed.

Claim 3
Dependent Claim
11 words
The method of claim 1 wherein the gas is carbon dioxide.
Claim 4
Dependent Claim
17 words
The method of claim 2 wherein the superatmospheric pressure is maintained between 50 p.s.i. and 1000 p.s.i.
Claim 5
Dependent Claim
18 words
The method of claim 3 wherein the pressure differential maintained during transfer is 10 p.s.i. to 150 p.s.i.
Claim 6
Dependent Claim
16 words
The method of claim 4 wherein the temperature of the melt is at least 212° F.
Claim 7
Dependent Claim
22 words
The method of claim 5 wherein the amount of gas dispersed within each gram of melt is 0.5 ml. to 15.0 ml.
Claim 8
Dependent Claim
31 words

Claim 9
Dependent Claim
24 words
The method of claim 7 wherein the second pressure vessel is vented to atmosphere through means which permit precise control over the exiting gas.
Claim 10
Dependent Claim
24 words
The method of claim 8 wherein the pressure in the second pressure vessel is maintained at a constant value from steps (d) through (f).
