Abstract
Abstract Polymorphic particulates formed by rapidly chilling molten fatty material to yield an unstable crystal form thereof are formed into a gas-fluidized bed wherein the gas rapidly absorbs heat of transformation of the particulates into a stabler crystalline form, and tempered particulates are withdrawn from the bed. Residual latent heat of crystallization also is absorbed by the gas and the tempered particulates resist appreciable agglomeration under conditions of storage.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A process for tempering particulates having crystallizable, continuous polymorphic fatty phase, at least the exteriors of said particulates having been crystallized rapidly to yield an unstable crystal form of said fatty phase, which comprises: forming said particulates; admitting said formed particulates into a fluidized bed; supporting said particulates with cooling gas at a temperature and for a time sufficient for said cooling gas to absorb heat of transformation of said particulates into a stabler crystal form, the outlet temperature of said cooling gas being less than the Wiley Melting Point of said stabler crystal form; venting spent cooling gas from said bed; and withdrawing tempered particulates from said bed whereby withdrawn tempered particulates resist appreciable agglomeration upon their collection.
Claim 2
Dependent Claim
119 words
A process for tempering particulates having crystallizable, continuous polymorphic fatty phase, at least the exteriors of said particulates having been crystallized rapidly to yield an unstable crystal form of said fatty phase, which comprises: forming said particulates; admitting said formed particulates into a fluidized bed; supporting said particulates with cooling gas at a temperature and for a time sufficient for said cooling gas to absorb heat of transformation of said particulates into a stabler crystal form, the outlet temperature of said cooling gas being less than the Wiley Melting Point of said stabler crystal form; venting spent cooling gas from said bed; and withdrawing tempered particulates from said bed whereby withdrawn tempered particulates resist appreciable agglomeration upon their collection.
Claim 3
Dependent Claim
13 words
The process of claim 1 wherein said fatty material comprises a fatty emulsifier.
Claim 4
Dependent Claim
12 words
The process of claim 1 wherein said fatty material comprises triglyceride fat.
Claim 5
Dependent Claim
12 words
The process of claim 1 wherein condiment is comprised in said particulates.
Claim 6
Dependent Claim
16 words
The process of claim 1 wherein said particulates are formed by spray chilling of an atomizate.
Claim 7
Dependent Claim
12 words
The process of claim 1 wherein said particulates are formed by flaking.
Claim 8
Dependent Claim
26 words
The process of claim 1 wherein the inlet temperature of said cooling gas is less than the bulk temperature of said particulates formed into said bed.
Claim 9
Dependent Claim
20 words
The process of claim 1 wherein said cooling gas absorbs remaining heat of crystallization of said particulates in said bed.
