Hydro-Fracture Resistance Properties of Hura crepitans Seed Relevant to Handling and Processing | Chapter 08 | Current Trends in Food Science Vol. 1
During harvesting, handling and
dehulling, agricultural materials including seeds were subjected to several
static and dynamic pressures that may affect the quality of the kernel if not
properly handled. This work therefore studied the effects of moisture content
on some compressive properties of Hura crepitans as a preparation for the
design of the seed dehulling machine. Hura crepitans seeds were conditioned to
four different moisture contents (9.3, 12.6, 15.6, and 17.8% db). The effect of
moisture contents on energy at yield, energy at break, compressive load at
yield, compressive load at break, compressive strain at yield and at break and
compressive stress at yield and at break were studied using Instron testing
machine (Model 3369). The results of the experiment show an increase in load at
break from 44.87 to 356.27N; Load at yield from 10.87 to 83.06 N; and decrease
in energy at yield from 0.262 to 0.021J; energy at break from 2.292 to 0.258 J;
compressive strain at yield from 0.311 to 0.160 mm/mm; compressive stress at
break from 2.809 to 0.384 mm, with increase in moisture in the range studied. The
effect of moisture content on all the properties studied were significant
(p> 0.05). These result showed that the compressive force properties of Hura
crepitans is moisture dependent. The data reported in this work will be of
great help during the design of Hura crepitans seed harvester, dehuller,
cleaning and sorting equipment for the seed.
