In large part of the world apple juice is one of the most popular fruit drinks. Bertuzzi can supply complete apple and pear processing plants for the production of cloudy and/or clear juice, as well as puree. In these last decades Bertuzzi installed apple and pears juice production lines in many countries such as Italy, China, Russia and more.
Washing and sorting
Apples and pears are received in the Bertuzzi washer InoxAll where, by immersion in the water and thanks to a Jet System, the surface of the fruits is washed. Fruits are then rinsed by a shower of fresh water on the elevator that takes the fruits to the subsequent sorting operations.
In order to guarantee the best quality of the final products, rotten and unripe fruits must be discarded. The Bertuzzi universal sorting line Selinox allows to efficiently inspect the fruits, by making them slowly rotate on a roller belt conveyor under the sight of the operators.
The first step for the production of juice and puree is to chop the fresh apples and pears into suitable granulometry for the production of juice and/or puree. Bertuzzi produce Choppers with different capacities, ranging from 1 to 10 ton/h, and with different optionals to match the characteristics of the fruit to be processed.
The chopped product is transferred to the belt press. In some applications the chopped product is pre-heated by means of a tube-in-tube heat exchanger or a tubular cooker and enzymized.
For high quality clarified apple juice, depending upon application, clarification can be performed by an enzymatic treatment group followed either by Vacuum Filter or by Ultrafiltration. Both system are designed to reach a very low degree of turbidity, preserving the organoleptic properties (colour, taste, aroma, etc.) of fresh apple.
For high quality puree production (both single strength and concentrated) Bertuzzi is proud of its highly versatile refiner and turbo extractor TurboMax.
The machine is supplied with inverter to adjust the rotation speed for the different applications and may be equipped to operate under inert gas blanket to protect the product against oxidation. The same machine is the basis of Bertuzzi cold peeling system.
Optionally, the juice and the puree can be concentrated. The rising film plate evaporator model Flashterm is specifically designed for the treatment of clear or low viscosity juices, while the forced circulation evaporator model Frumaco is designed for puree concentration.
Both evaporators can be equipped with an Aroma Recovery Unit ARU.
Juices and purees, concentrated or natural single strenght, can be sterilized or pasteurized depending by the specific request of the application. Purees, natural or concentrated, are treated with tube-in-tube heat exchangers while clear or cloudy juices, natural or concentrated, with plate heat exchangers(/thermaltreatment#240).
In case of sterilization, the product can be filled in aseptic bag in drums or in box thanks to Bertuzzi Aseptic Fillers or in any type of aseptic filling machine (aseptic carton box, aseptic pouches...), while the pasteurized product can be filled in durms with liner or in any type of hot or cold filling machine (glass, PET, pouches...)
All Bertuzzi lines are designed according to the international food grade requirements and to be fully cleanable by exploiting integrated cleaning procedures and systems or centralized and fully automatic CIP system. The Bertuzzi CipMatic is specifically designed to guarantee a perfect and efficent CIP of the fruit processing plants.
