Abstract

The physical properties of agricultural products are essential in designing machines, equipment, and systems for efficient processing operations. Two periwinkle varieties, viz Tympanotonus fuscatus (Linnaeus, 1758) and Pachymelania aurita O. F. Müller, 1774, were utilised in this study to investigate and determine their physical properties relevant to the design of efficient processing equipment. The geometric (axial dimensions, mean diameters, surface area, sphericity, aspect ratio) and gravimetric (bulk and true densities, mass, and porosity) properties were measured. The averages for the major diameter, arithmetic mean diameter, geometrical mean diameter, and surface area were highest in the T. fuscatus variety. In contrast, the minor diameter, sphericity, and aspect ratio were highest in the P. aurita variety. The average bulk and true densities, porosity, and average periwinkle weight for T. fuscatus were higher than the P. aurita variety. Tukey's pairwise comparison analysis carried out on all the physical properties of the T. fuscatus, and P. aurita varieties of the periwinkle shells revealed a statistically significant difference at P < 5%.

与加工设备设计相关的两个长春花品种物理性质的比较分析

农产品的物理特性对于设计高效加工操作的机器、设备和系统至关重要。本研究使用了两个长春花品种，即Tympanotinus fuscatus（Linnaeus，1758）和Pachymelania aurita O.F.Müller，1774，来研究和确定它们与高效加工设备设计相关的物理特性。测量了几何（轴向尺寸、平均直径、表面积、球形度、纵横比）和重量（体积和真实密度、质量和孔隙率）特性。大直径、算术平均直径、几何平均直径和表面积的平均值在褐毛T.fuscatus品种中最高。相反，金合欢品种的小直径、球形度和长径比最高。褐毛T.fuscatus的平均体积密度、真密度、孔隙率和平均长春花重量均高于金黄色P.aurita品种。Tukey对长春花壳的T.fuscatus和P.aurita品种的所有物理特性进行的成对比较分析显示，差异具有统计学意义，P＜5%。
