Alcryo

A cryogenic continuous pre-treatment system for the entire grape, red or white, preventing undesirable premature fermentation and increasing the components extracted without alcohol and safeguarding the hygienic integrity of the product.

The two-stage system consists of a conveyor then a belt elevator that conveys the grapes directly to the destemmer-crusher system.

On board the machine, along the entire chain, are devices that inject and spread the cryogenic fluid, in this case carbon dioxide stored in liquid form, which turns into a solid state on contact with the atmosphere, producing dry ice, and then transforming into a gas, consequently absorbing thermal energy and lowering the temperature of the product. The entire unit is insulated to prevent counter-productive heat from re-entering the machine as well as inerting the production process.

The results of functional experience on-site have shown tangible temperature reductions of between 20-25°C, for production flows of 10 tonnes/hour, when the system is used efficiently and reliably.
