“…Similarly, the true density of COD was 40.86% more than AGT. These findings reveal that the tender coconuts display relatively a more density than that reported by Pandiselvam et al () and Alonge and Adetunji () who studied the Indian and Nigerian matured coconuts, respectively. The high density liberates more mass per unit volume on the holder, warranting more torque to trim the coconut.…”

“…The lowest h 1 , h 2 , h 3 , and h 4 were noticed in COD cultivar. The magnitude of the husk thickness of matured MOD and COD reported by Pandiselvam et al () is significantly less compared to that of the young MOD and COD. The highest husk thickness was observed in top orientation (pedicel end), followed by bottom orientation (fruit base), left orientation, and right orientation.…”

“…The matured Nigerian coconut seeds had a higher diameter (184.93 mm) (Alonge & Adetunji, ) than AGT and young Thai coconut. The average weight of the MOD and COD coconuts of 12‐month maturity reported by Pandiselvam et al () was low (1.02 ± 0.27 kg and 1.01 ± 0.06 kg) compared with the young (6 months maturity) MOD and COD coconut (1.35 ± 0.03 kg and 1.04 ± 0.13 kg).…”

“…Knowledge of the shape of coconut, testa thickness, moisture content, and dynamic friction of testa is required for the development of testa removing machine for coconut. Coconut kernel parameters including thickness, weight, moisture content, and density play a major role in the design of pulverizing, grating, and slicing machine (Pandiselvam et al, ).…”

The physical properties such as tender coconut size, weight, husk thickness, and husk moisture tender content play a vital role in the development of an efficient and ergonomic trimming machine. The important physical properties of tender coconuts of cultivars namely Kulasekaran Green Dwarf (KGD), Andaman Giant Tall (AGT), Ganga Bondam (GB), Malayan Orange Dwarf (MOD), and Chowghat Orange Dwarf (COD) were determined. The important properties including weight, diameter, height, husk thickness, husk moisture content, shell diameter, shell height, and shell thickness were high for nuts of AGT and low for COD nuts. The average bulk density, true density, and porosity of AGT were 332.47 kg·m−3, 1,196.67 kg·m−3, and 72.21%, respectively. The husk weight and volume of water of AGT were 87.77% and 12.39% high, respectively, compared with COD. In the correlation study, the coconut weight correlated positively (r = 0.791) with the diameter and vertical distance between the shell and the fruit base (r = 0.813). The principal component analysis suggested that the cultivars GB, KGD, and MOD have similar physical properties to COD and AGT. Thus, the present investigation documents crucial basic information to design an efficient and superior tender coconut trimming machine. Practical Applications Transportation of intact tender coconut is difficult, and thus a manually trimmed tender coconut shape of a cylindrical side with a conical top has gained more importance among the domestic and international consumers owing to its fresh and natural taste and attractive shape. The high transportation cost of tender coconut, shortage of manpower to trim the tender coconut, and the high production cost to make the shape of the cylindrical side with a conical top have created an urgent need for the development of trimming machines. The physical properties of tender coconut and its correlation studies are very important for the designing and development of a trimming machine.
