Influence of the Physical Characteristics of Chives Bulbs on Choosing the Sieve Type for Calibration

Abstract

The paper presents a research method for the settlement of necessary sieves orifices dimensions which are used at an installation for chive calibrating 2 sorts of chives (spherical and oblong) and 3 types of sieves were experimentally researched. The researchers observed that the sieve which best satisfies the calibration demands of the chive is the sieve with circular improved orifices, which has a double sieving capacity as compared to the one with circular simple orifices. The sieve with bars has an increased sieving capacity, but it doesn’t meet the demands regarding the product purity. For a flow of 1000 kg/h the necessary surfaces of the sieves for standard sorts of chives were calculated, and then the share of these sorts in the total quantity of product was established.
