A mechanical peeler cum juice extractor was designed and developed for simultaneous peeling and juice extraction of kinnow and sweet orange fruits. Based on the designed components and prior optimization of operational parameters for peeling of both the fruits, a functional machine was developed. Major components of the machine include spur gear assembly (Φ 102 mm and Φ 76 mm), two fruit holders (Φ 30 mm), revolving shaft with length 570 mm, clearance of the tool for peeling 25 mm and cutting knife with length 80 mm, respectively. This peeler was operated using a motor, gear assembly and the combination of pulleys. The juice extractor was also fitted with a conical hopper having a flattened base to facilitate the juice extraction of peeled fruits. For performance evaluation, fruit rotation speed was considered as independent parameter and was varied at 220, 260, 280, 300, 360 rpm, whereas peeling time (s), peeling efficiency (%), peel remained on fruit (%) and juice loss (%) were taken as dependent parameters. The machine resulted in best performance at fruit rotational speed of 220 rpm (kinnow) and 260 rpm (sweet orange) with higher peeling efficiency and minimum juice loss. The capacity for peeling and juicing operation was 60–90 kg/h (kinnow) and 50–60 kg/h (sweet orange), respectively. This composite peeling cum juice extractor machine can find its applicability in cottage citrus fruit juice processing industries as well as for the domestic juice sellers.

设计和开发了一种机械去皮机兼榨汁机，用于同时对kinnow 和甜橙水果进行去皮和榨汁。基于设计的组件和预先优化两种水果去皮的操作参数，开发了一种功能机器。该机主要部件包括正齿轮总成（Φ102mm和Φ76mm）、两个水果架（Φ30mm）、长度570mm的转轴、去皮工具间隙25mm和长度80mm的切刀， 分别。该削皮机使用电机、齿轮组件和滑轮组合进行操作。榨汁机还配备了一个锥形漏斗，该漏斗有一个扁平的底座，以方便去皮水果的榨汁。对于绩效评估，水果转速被认为是一个独立的参数，在 220、260、280、300、360 rpm 之间变化，而剥皮时间（s）、剥皮效率（%）、果皮残留量（%）和汁液损失（%）分别为作为依赖参数。该机器在 220 rpm（kinnow）和 260 rpm（甜橙）的水果转速下获得最佳性能，具有更高的去皮效率和最小的果汁损失。去皮和榨汁操作的能力分别为 60-90 kg/h（kinnow）和 50-60 kg/h（甜橙）。这种复合式去皮兼榨汁机适用于山寨柑橘类果汁加工行业以及国内果汁销售商。果皮保留在水果上 (%) 和果汁损失 (%) 被视为相关参数。该机器在 220 rpm（kinnow）和 260 rpm（甜橙）的水果转速下获得最佳性能，具有更高的去皮效率和最小的果汁损失。去皮和榨汁操作的能力分别为 60-90 kg/h（kinnow）和 50-60 kg/h（甜橙）。这种复合式去皮兼榨汁机适用于山寨柑橘类果汁加工行业以及国内果汁销售商。果皮保留在水果上 (%) 和果汁损失 (%) 被视为相关参数。该机器在 220 rpm（kinnow）和 260 rpm（甜橙）的水果转速下获得最佳性能，具有更高的去皮效率和最小的果汁损失。去皮和榨汁操作的能力分别为 60-90 kg/h（kinnow）和 50-60 kg/h（甜橙）。这种复合式去皮兼榨汁机适用于山寨柑橘类果汁加工行业以及国内果汁销售商。
