Title: PROCESS FOR MAKING MICRO-AERATED CHOCO-MATERIAL
Abstract:
There is described a process for producing a micro-aerated choco-material the process comprising the steps of: (I) mixing a choco-material under a high shear of at least 200 s-1,the choco-material having a plastic viscosity before aeration as measured according to ICA method 46 (2000) of from 0.1 to 20 Pa.s, and (II) passing the choco-material from step (I) through an injection zone located between two regions held at different pressures, (III) injecting inert gas at a gas pressure of from 2 to 30 bar into the choco- material as it passes through an injection zone using a gas depositing means at a nominal gas flow rate (Fv) which is within the values of Fv that are calculated from equation (2) P = —A Fv2 + B Fv + C (2) Where P represents the porosity target of the micro-aerated choco-material in % measured under standard conditions, P being from 10 to 19%; and Fv represents the nominal volumetric flow rate of the inert gas in normal litres per minute (NL / min.); A,B and C are numerical constants (having the respective units to balance equation (2)); the numerical parts of each of these constants being: A from 0.06 to 0.07; B from 2.00 to 2.05, and C from 3.70 to 3.80; with the proviso that: (A) the flow rate calculated from equation (2) is based on a nominal throughput of the choco-material of 1000 kg / hour in the injection zone, the actual flow rate of inert gas injected in step (III) being adjusted where necessary from the calculated nominal flow rate Fv to match proportionally any differences from 1000 kg / hour in the actual throughout of the choco-material in the injection zone
