The aim of this research is to study some physical and mechanical

properties ofSodom apple (Calilropis procera). 10 help in designing and

developing ofspecific machine and their operations such as harvesting,

cleaning. grading and separation.

The main results in this study can be summari=ed asfollows:

Physical properties of Sodom apple seeds fruits: length= 5.19 - 6.98 mm.

width = 3.16 - 5. 87mm. thickness = 0.38 - 0.70 mm. geometric

diameter= 1.99 - 2.82 mm, arithmetic diameter= 3.21- 3. 77mm. flat

surface area = 7.07- 9.84 mm

• transverse surface area = 2.89

3 5.06mm2
• volume 4.12 - 11.68 mm • mass of1000 seeds = 5.84 - 7.05 g,
bulk density = 200.97 kg/m3
, real density = 929.50 kg/m3
and moisture
content= 8.43 % w.b.
Mechanical properties: The lowest values ofrepose angle for seeds were
on fiber glass followed by galvani=ed sheet, plywood, rubber and the
highest on perforated sheet (20.86°, 34.81°. 48.86', 55.63° and 62.46')
respectively. Tensile strength betweenfibers and seeds was 0.0986N.
