Abstract
Abstract A method for preparing a stable clear liquid release agent consisting of forming a uniform mixture of oils by agitating the oils at a temperature on the order of 74 DEG C followed by uniformly chilling the mixture with agitation to at least about 25 DEG C and working the chilled mixture. Preferably the mixture is precooled and homogenized prior to the rapid chilling step. The resultant blend of oils present a brighter and clearer appearance and is less suceptible to separation than conventionally blended oil mixtures.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A method for preparing a stable clear liquid release agent comprising a liquid blend of fatty oils the method comprising the steps of blending about 57 percent by weight of soybean oil, about 38 percent by weight of coconut oil and about 5 percent by weight of lecithin at a temperature of at least 65° C. to form a substantially uniform blend, chilling said blend uniformly to a temperature between about 20° to 25° C. to form a chilled blend, and working said chilled blend by agitation to provide a clear liquid release agent.
Claim 2
Independent Claim
94 words
A method for preparing a stable clear liquid release agent comprising a liquid blend of fatty oils the method comprising the steps of blending about 57 percent by weight of soybean oil, about 38 percent by weight of coconut oil and about 5 percent by weight of lecithin at a temperature of at least 65° C. to form a substantially uniform blend, chilling said blend uniformly to a temperature between about 20° to 25° C. to form a chilled blend, and working said chilled blend by agitation to provide a clear liquid release agent.
Claim 3
Dependent Claim
21 words
The method of claim 1 wherein said oil blend further includes an effective amount of a flavor additive and a colorant.
Claim 4
Dependent Claim
18 words
A stable clear liquid release agent comprising the fatty oil blend produced by the method of claim 1.
Claim 5
Dependent Claim
42 words
A fatty oil blend prepared by the method of claim 1 consisting essentially of: Soybean Oil: about 57 wt. % Coconut Oil: about 38 wt. % Lecithin: about 5 wt. % and further including an effective amount of color and flavor additives.
Claim 6
Dependent Claim
24 words
The method of claim 1 further including the steps of cooling to an intermediate temperature and homogenizing said blend prior to the chilling step.
Claim 7
Dependent Claim
22 words
The method of claim 1 wherein said fatty oils are heated to a temperature of about 74° C. during said blending step.
Claim 8
Dependent Claim
19 words
The method of claim 5 wherein said blend is cooled to about 38° C. prior to said homogenizing step.
Claim 9
Dependent Claim
94 words
The method of claim 1 wherein said blend is chilled by passing said blend through an annular space defined between the bore of a jacketed tube and a rotating shaft with outwardly extending scrapers, the tips of which contact the wall of said bore for removing films of blended oil from the wall of said bore, said jacketed tube being cooled for the removal of heat from said blend which is formed by said annular space into a relatively thin layer for the substantially uniform removal of heat from said layer of said mixture.
Claim 10
Dependent Claim
15 words
The method of claim 1 wherein said chilled blend is worked by high speed agitation.
