Mango processing

Bertuzzi designs and manufactures mango pulp processing machinery for the production of high quality mango juice and puree, either single strength or concentrated. We can supply complete mango processing plants as well as single machines to meet specific requirements.

Washing and sorting

Our universal washing station InoxAll is suitable for cleaning any fruit destined to the industrial transformation. The unit takes the fruits through two subsequent washing processes: by immersion in a basin and by shower on an elevator.
After being washed, mangoes are fed to our universal sorting station Selinox where they can be efficiently inspected by the personnel.
Finally, we advise to complete the cleaning with a brushing machine: the rotating brushes allow to remove any extraneous matters and any dirt that has adhered to the fruits.

Stoning and pulp refining

Our mango destoners (Super Mango Destoner and Jumbo Mango Destoner) have been especially designed to automatically destone and peel fresh mangoes: by precisely separating stones and peels from pulp, they allow to maximize both the yield and the quality of the final product.
The unrefined mango pulp is sent to our single stage pulper SuperCreamer, which refines the puree to the required level, while ensuring low degree of air absorption and therefore low oxidation.
For enzymatic deactivation the mango pulp can be sent to a tubular preheater. The machine can be also adopted to pre-heat the unrefined pulp before it is refined by SuperCreamer, in order reach a higher production yield.
A centrifugal decanter can be adopted to eliminate black specks and for a further delicate depulping.

Deaeration or concentration

The possible final products of our mango processing lines are natural puree or concentrated puree.
In the first case the natural puree is deaerated in order to extend product shelflife. The deaerator is used for the elimination of air incorporated in liquid or thick alimentary products, by nebulization under vacuum – in order to avoid oxidation. The processing unit can be completed with integrated aroma recovery: the aromatic vapors are condensed and newly incorporated directly into the product by means of a recovery device supplied with the machine.
In case of concentrated puree, the refined puree is pumped to a thin-film continuous evaporator. The versatility of our swept evaporators is really unrivalled: they can process easily low-pulp or high-pulp juices, delicate or thermo-resistant juices, low or high viscosity products. The residence time is among the shortest possible and the concentration is achieved in one sole passage. The outstanding consequence is that the concentrate is at the top of the quality scale.

Sterilization and filling

Our tube in tube sterilizers are composed of four concentric pipes. The units are completely skid-mounted in order to simplify the installation on site: they just have to be connected to the product input/output and to the utilities (steam, condensate, compressed air, cooling waters).
