Deseeding

Pomegranate is one of the most difficult fruits to process and an incorrect technology can contaminate the juice with tannic elements, thus damaging its quality. Megra is regarded as the most appropriate deseeding machine on the market and it has been adopted all over the world (United States, India, Iran, China, Azerbaijan between others).
The special construction allows to change the working parameters for an optimized operation of the machine. The machine has a working capacity of 5-6 tons/hour input of fruit and the yield of seeds can reach up to 99%, minimizing the presence of fragments of peels and membranes.

Juice extraction

The juice extraction system we supply is a membrane press, which has the big advantage of providing a very soft pressing of the pomegranate arils, preserving the organoleptic characteristics of the juice. The obtained juice is processed by a vibro-screener in order to remove any eventual solid particle.

Juice clarification

The juice coming from the press is pasteurized and pumped to treatment tanks, where enzymes and chemicals are added to increase the separation. The treatment has a duration of 3 to 4 hours. Upon completion of the treatment the juice is sent to an ultra-filtration line for clarification.

Juice concentration

Optionally, juice can be concentrated. Flashterm is a plate evaporator designed for the treatment of clear or low viscosity juices. This concentration group can be equipped with a thermo compressor and an aroma recovery unit.
