What is a batch freezer?
A batch freezer is a dedicated piece of equipment used to prepare gelato. Essentially it simultaneously freezes and whips the liquid mixture to create a smooth and consistent finished texture. It does this by rotating a blade inside the barrel of the machine. The blade performs two important tasks:
The spinning blade is also responsible for creating even-sized ice crystals throughout the mixture to ensure the even freezing of the gelato.
Horizontal vs. Vertical
Generally speaking, batch freezers can either be ‘horizontal’ or ‘vertical’ – this refers to the direction of the barrel and blade.
There is no doubt that horizontal batch freezers are more popular – in fact, there are only a small handful of vertical batch freezers in operation in Australia – but that doesn’t necessarily mean they are better. Let’s take a look at the main differences:
Horizontal batch freezers seal the mixture in the barrel for the freezing process as opposed to a _vertical_batch freezer, which remains open at the top. This means:
Cattabriga Effe 6
At Gelateria Gondola we use a _vertical_batch freezer to make our award-winning gelato, but not just any old machine – we use a Cattabriga Effe 6.
Otello Cattabriga, a talented Italian engineer, who designed a mechanical system to mimic the ‘stir & stick’ technique of the traditional Italian ‘gelatieres’, patented the first Cattabriga vertical batch freezer in 1927. Since then, his name has become synonymous with the world’s best gelato as well as technological advancement in the industry. The Effe 6 has no match in the industry, nor in gelato history. It is a tradition that we are proud to carry on through our partnership with Crew Australiawho supplies Cattabriga equipment to the Australian market.
At Gelateria Gondola we are honoured to be the NSW brand ambassador for the Cattabriga Effe 6 – anyone interested in seeing it in operation is welcome to visit our store for a demonstration, whether you’re interested in purchasing one for your own gelataria or simply want to see how your favourite gelato is made. The true test is in the tasting though so be sure to try a scoop or two when you visit to taste the difference.
