Concentration technology

Bertuzzi supplies a wide range of evaporators specifically designed to process fruit juices and fruit purees for the production of high quality concentrate matching the highest requirements of the international market

General Overview

Depending on the characteristics of the juice or puree (variety, viscosity, solid contents, thermal sensibility) to be concentrated, Bertuzzi produce different model of continuous evaporators:

All the Bertuzzi evaporators are fully customized to produce high quality concentrate matching the most stringent requirements of the international market.

Thin-film continuous evaporator model Luber

Frumaco / Tomatech

Bertuzzi forced circulation evaporator, with tube-nest exchangers, model Frumaco designed specifically to concentrate viscous products like mango, apricot or apple purees. For the production of tomato paste Bertuzzi designed a dedicated forced circulation evaporator model Tomatech.

As the plant is working under vacuum conditions, the boiling temperature is very low and the stress of the product is reduced to a minimum. Low boiling temperature also means low fouling of the heat exchange surfaces.

Flashterm

The Flashterm rising film plate evaporator is dedicated to the concentration of fruit juices with low solid content like pomegranate, pineapple, passion fruit or apple juices.

Main features of the Bertuzzi Flashterm are:

Luber

The Luber is a simple effect evaporator, thin film scraped Surface type, designed to concentrate in a single fast passage either thermo-sensitive liquid products or viscous products.

The juice is fed to the upper part of the evaporator, towards a centrifugal distributor, that is designed to spread the juice over the cylindrical inner surface of the evaporator.
By gravity, the film falls in spiral form toward the lower part of the evaporation cylinder while the vapours are collected in the centre of the evaporator.
When reaching the bottom cone, the juice is in-one-passage concentrated to the required degree in a very short time.

Due the capability to concentrate even viscous liquids it is also used as finisher for pre-concentrated products.

ARU: Aroma Recovery Unit

All the evaporator can be integrated with a the ARU. The aroma can be filled in dedicated container or jar or automatically reinjected into the concentrate.
