Automatic Food Grade Stainless Steel 304 Ice Cream Production line

-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
