Berry fruit destalker ODS-3/R

 

APPLICATION

The machine is designed to remove stems, stalks and leaves from frozen berry fruits such as: gooseberry, currant, berry, bilberry, chokeberry, sea-buckthorn, black elder etc. To ensure correct result of the machine operation, the product fed to the discharge must be deep-frozen to temperature of min. –24oC.

Note: When rowan berries are destalked, the fruits should be firm and free of clusters.

PRINCIPLE OF OPERATION

The frozen fruits fed to the hopper fall into the first (breaking) chamber, where they are crushed by the rotating crusher. In addition to the crushing function, the special construction of the crusher fingers also fulfils transport function by moving the fruits to the space, where destalking takes place. Inside the drum, the fruits are set in violent motion generated by the rotating elements of the screw. Between the screw flights there are mounted the elements generating additional friction of the fruits between each other and reducing speed of the fruit mass movement along the screw. The fruit residence time inside the machine drum has crucial influence on the destalking efficiency. The drum hole edges remove the fruit stems, stalks and leaves etc. that fall into the trough. The fruits mixing in the working space are conveyed by the screw to the discharge hole, under which they are collected into the bags, containers or are fed to the downstream machine in the line. The adjustable feet make it possible to position the machine on each floor and change upward slope angle. With that angle it is possible to correct quality of the fruits being destalked, because each raw material type may behave differently during destalking. The optimum machine operation angle must be determined by tests for each raw material type and its different classes.
