DEscriptION
-Formulation:
The ingredients used in ice cream production are: fat;milk solids-non-fat (MSNF);sugar/non-sugar sweetener;emulsifiers/stabilisers;flavouring agents;colouring agents.
-Weighing, measuring and mixing:
Generally speaking, all dry ingredients are weighed, whereas liquid ingredients can be either weighed or proportioned by volumetric meters.
-Homogenisation and pasteurisation:
The ice cream mix flows through a filter to a balance tank and is pumped from there to a plate heat exchanger where it is preheated to 73 – 75deg for homogenisation at 140 – 200 bar, the mix is pasteurised at 83 – 85deg for about 15 seconds then cooled down to 5deg and transferred to an ageing tank.
-Ageing:
The mix must be aged for at least 4 hours at a temperature between 2 to 5degc with continuous gentle agitation. Ageing allows time for the stabiliser to take effect and the fat to crystallise.
-Continuous freezing:
•to whip a controlled amount of air into the mix;
•to freeze the water content in the mix to a large number of small ice crystals.
-Filling in cups, cones and containers;
-Extrusion of sticks and stickless products;
-Moulding of bars
-Wrapping and packaging
-Hardening and cold storage
