The chopper allows to reduce in pieces the whole fruit. During chopping an acidifying solution, prepared in a dedicated dosing group, is added to reduce the oxidation of the fruits. Mashed fruits are sent to the belt press for juice extraction.

Clarification / ultrafiltration

Obtained juice is fed to the plate pre-heater/cooler to treat the product to the optimal temperature for the following clarification treatment where enzymes and chemicals are added to facilitate the separation. Upon completion of the clarification treatment the juice is sent to the Ultra-filtration plant for its final clarification.
