Ice cream is frozen in two stages: Ice crystals are formed during dynamic freezing, where the ice cream mix is frozen and agitated in an ice cream machine to incorporate air, and grow during static freezing, where the partially frozen ice cream mix is hardened in a freezer without agitation.

The primary aim is to promote the formation of as many small ice crystals as possible during dynamic freezing and then preserve these small crystals during static freezing and storage. As the freezer bowl absorbs the heat in the mix and brings it below its freezing point, a layer of ice freezes to the wall of the cold freezer bowl causing rapid nucleation the birth of small ice crystals Hartel, Similarly, Russell et al.

Lower wall temperatures can lower the bulk temperature of the ice cream faster, reducing residence time and improving the ice crystal size distribution Russell et al.

When freezing your removable bowl, cover the top with cling film. This will help prevent water vapour in your freezer, as well as any ice that may fall in, from freezing to the inside of the bowl.

This will ensure that the freezer bowl wall temperature is as low as possible when the mix is added. Freezing the plastic container will remove any stored heat. In general, a lower draw temperature results in smaller ice crystals Arbuckle, Hartel argues that of all the factors affecting ice crystallisation that can be controlled, the draw temperature of the ice cream freezer bowl is probably the most significant.

To obtain a low draw temperature, the freezer bowl temperature must be as low as possible to give rapid heat removal. Heat transfer must also be as efficient as possible. This means using dasher scraper blades that contact the wall of the freezer bowl as they rotate to prevent a build up of ice.

Longer residence times are usually required to obtain a lower draw temperature.

Temperature fluctuations due to automated defrost cycles on home freezers contribute to higher rates of recrystallisation during storage.

The more times this cycle is repeated, the more recrystallisation is likely to occur. These target reduction figures are to ensure that we have the necessary mix composition after heating.

First weigh your pan and record its weight. My 23cm diameter pan weighs g. If my total weight after 25 minutes heating is greater than g, I will continue heating until the weight falls to g or less. Here in the U. Pasteurised ice-cream shall be obtained by the mixture being heated— to a temperature of not less than Ice cream needs to be pasteurised in order to destroy all pathogens and the enzyme phosphatase that may be harmful to health.

This is just as important for those of us making ice cream to sell as it is for you guys making ice cream at home. Foam formation and its stability is important for texture and for the retention of air that is incorporated into ice cream during dynamic freezing.

Heating milk so that the whey proteins undergo partial protein unfolding yields a more voluminous and more stable foam and improves the emulsifying characteristics of the proteins Philips et al. In this temperature range, whey proteins undergo reversible unfolding, which improves foaming, emulsification, and texture.

Yes I think that using malted milk powder will have the same beneficial effects on ice cream as using skim milk powder and may even be more beneficial if there is malted barley and wheat flour in the malted milk powder.
