The dissimilarity in the engineering characteristics of white mold which leads a difficulty in soybean seeds separating , this difference in the engineering characteristics of the white mold constructions differ according to the degree of infection and the period of storage, which results in irregularly from wide range in shaped white mold constructions which leads to the separation efficiency decreases and repetition of the separation processes. The aim of the study is to decide the engineering properties of American soybean seeds and white mold (Sclerotinia sclerotiorum) imported from the USA to Egypt. The experimental work was carried out until 2018 in the Agricultural Engineering Department, Faculty of Agriculture, Tanta University, Egypt. The engineering properties can be used in the design and development of handling, transportation, storage and separation equipment. Seed dimensions were tested at moisture levels between 8.85 and 12.30% (wet basis). The results showed that by changing the moisture content the average dimensions of the soybean seeds were changed, respectively, from 5.39 mm to 5.96 mm, and the width from 4.76 mm to 5.16 mm. Thickness changes from 3.98mm to 4.38mm. The size is 55.8 to 71.93mm3, the average geometric diameter is from 4.66 to 5.05mm. Arithmetic average diameter from 4.7 to 5.10 mm. Sphericity decreased from 86.94 to 85.10%. Also, the surface area changed from 68.29 to 80.17 mm 2. On the other hand, the dimensions of the hardening of the white mold ranged according to the place imported, with the length ranging from 5.85 to 20.31 mm, the width from 1.32 to 4.39 mm, the thickness from 0.88 to 3.07 mm, and the size from 9.75 to 75.19 mm3, the mean geometric diameter from 2.64 to 5.22 mm, the arithmetic mean of diameter from 3.02 to 8.07 mm and spherical diameter from 15.98 to 58.81%. Also, the surface ranged from 22 to 85.85 mm 2. These results showed that the difference between the physical properties of soybeans and white rot is not strong in terms of length, width and thickness in this case, which impedes the separation processes.
