String bean is a leguminous crop and is bean-shaped and black, white, brown, green or speckled in appearance. Talas region is the major cultivator of string beans in Kyrgyzstan. Despite the economic potential of string bean, little is known about it is physical properties. The processing operations are predominantly manual. The manual processing of string bean is time consuming and laborious, the current conditions are generally unsanitary and unhygienic. Presently, the equipment used in processing of string beans have been generally designed without taking into consideration of the physical properties of string beans. Those properties include the size, mass, bulk density, true density and sphericity. The lack of knowledge on the physical properties of string beans leads to reduction in working efficiency and increase in product losses. Investigation of physical and mechanical properties of string beans is essential for design of equipment for harvesting, processing, transportation, cleaning, sorting and separation and packaging. In this research some physical properties of string bean grains were evaluated such as axial dimensions, arithmetic mean diameter, geometric mean diameter, thousand grain mass, sphericity, surface area, aspect ratio, porosity, true and bulk density and grain volume at moisture content of 7.1-8.1% dry basis. The experimental results will be presented.
