Apricot, peach and plum processing

Being a product for transformation into various delicacies (such as juices, yogurt bases, baby foods, ice cream and jam) fruit puree has always been a focus in Bertuzzi’s 80 year-old history.
If apricots or peaches, cherries or plums, there is hardly any application for which Bertuzzi is incapable in offering the right solution to meet its customers’ needs.

Washing and sorting

Stones fruits (apricot, peaches and plums) 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. 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.

In smaller plants fruits are manually fed directly into washing basin model InoxAll

Pitting

Expeller Maxi is a destoning machine fitted for the treatment of peaches, plums, apricots and cherries. This patented machine has a capacity of up to 18000 kg/h of fresh fruit and it is capable of processing also hard and large fruits without severe losses in yield.
JumboCreamer is used to clean the stones coming from Expeller Maxi in order to recover all possible pulp.

Cold peeling and cooking

For a perfect separation of flesh and juice from peels Bertuzzi is proud of the highly sophisticated pulper, refiner and turbo extractor model Turbomax. The machine can be supplied with inverter suitable to adjust the rotation speed and with an inert gas injection device, for protecting product against oxidation. The same machine is the basis of our cold peeling system.

Puree concentration

Puree can be optionally concentrated. Depending on the characteristics of the product and of the plant, purees can be concentrated either by the forced circulation evaporator model Frumaco or by the thin film scraped surface evaporator model Luber . Luber is designed to concentrate in a single fast passage either thermo-sensitive liquid or highly viscous products.

Puree sterilization and filling

The stone fruit puree, concentrated or natural single strenght, can be sterilizied or pasteurized depending by the specific request of the application, by a tube-in-tube heat exchanger.

Once sterilized the product can be filled in aseptic bag in drums or in box thanks to Bertuzzi Aseptic Fillers.
