Blast chillers and freezers

Blast chilling and blast freezing can be a big advantage in most galleys allowing food preparation to be more efficient, as foods that have been blast chilled can be kept for up to 4 days before re-heating.

Blast freezing or shock freezing allows food to be rapidly frozen with reduced cell damage, giving foods a better taste and appearance when defrosted.

Food does not loose it’s appearance, taste or affect the texture. The rapid chilling avoids bacteria growth and reduces the risk of associated health problems.
