10、 20046/1/2004Page 17The peeled tomato is fed to one or more sorting conveyors.Here peeled tomatoes not suitable for dicing and canning are rejected.This process can be achieved either manually or by means of optical sorting units mounted on the line.Peeled tomatoes are diced into pieces of various s
11、izes according to the market demand. The dicing unit receives tomatoes and can chop them with three different cuts depending upon the requirements.Dimensions of the diced product can be adjusted by changing a few parts.SORTING&DICINGSIG Manzini S.p.A.

12、toes move from the dicing unit together with their juice. The product is then fed to a vibrating separator, fitted with a perforated screen, where the dices are separated from the liquid which drains out through the holes of the vibrating screen. The liquid is then collected into a tank and fed to t
13、he tomato paste line, while the dices are discharged at the end of the vibrating screen.LIQUID SEPARATIONSIG Manzini S.p.A.

14、 designed to run particulated products with different sizes of chunck and with a very little liquid content. The pump can keep the integrity of the product.An outstanding feature of this pump is that the feeding opening dimensions are the same as the diameter of the cylinders.PISTON PUMP P12SIG Manz
