“…Automatic-sugarcane peeling machine was designed by Xinfeng (2014) and they have adopted the slider-crank mechanism, which is reliable with drudgery reduction and with high efficiency. Manjunatha et al (2012) [5] explained about development and performance evaluation of a power operated garlic peeler with a cylinder-concave mechanism with peeling efficiency, yield of peeled garlic and unpeeled garlic, damage and peel separation were 86.6, 86.2, 4.7, 9.15and 96%, respectively with a machine throughput capacity of 27 kg/h.…”

Sugarcane is the most common commercial crop grown worldwide, which is grown in tropical and subtropical countries of the world. Sugarcane is the world's second largest crop in production with about 188.25 million metric tonnes of cane during 2018-19 and provides 60 to 70% of the world sugar. Sugarcane is a common raw material for sugar and jaggery. As the production is high, the development of sub products from sugarcane is also high where juice has its equal importance. Additionally, cane juice is mostly used as a "refreshner" during summer to replace the artificial beverages. The sugarcane juice can be obtained by squeezing through extractors. Apart from that, as per health point of view many of consumers show more interest on sugarcane juice than other cool drinks. In major countries of South Asia, sugarcane juice extraction is the main occupation for small scale road side venders. The extracted juice quality can be improved by separating the sugarcane peel prior to juice extraction. The ancient method of sugarcane peeling is done manually with help of knife. But this method is more tedious, ineffective and prone to injuries. Moreover, the extracted juice contains a lot of suspended solids and impurities, which affects the quality, taste and colour due to presence of wax and other plant impurities. To reach the above limitations, a low cost sugarcane peeler for small scale venders was developed. The maximum value of machine production efficiency obtained as 74.9% with the peeling capacity of 3 canes per minute.

“…Moreover, the friction generates heat, meaning that the fruits can easily become partially cooked, which is undesirable. In the case of the shearing principle, peeling force is created by pressing and shearing-for instance, using rubber-covered rollers [19]. As the rollers rotate, the fruit is compressed, and shear causes the peel to crack and separate from the pulp.…”

This work describes the development, design, and parameter identification of a lychee peeling machine. The working principle of the machine combines two rollers with a pressing belt to separate the peel from the fruits. It was designed and its operational parameters identified on the basis of experimental data on the Thieu lychee, which currently covers about 80% of the plantation area in Vietnam. To this end, the first step was to measure the physical characteristics of the fruits, such as size, shape, and density. Moreover, the coefficient of static friction between lychees and rubber rollers, and the critical peeling force, were identified, with a view to optimizing the operational parameters later on. Results showed that a minimum tangential force of 10.5 N is needed to break the peel and separate it from the pulp. Based on the balanced force principle, various optimal machine parameters such as roller rotation speed, roller diameter, roller length, gap size between the two rollers, belt velocity, and minimum pressure of the belt were calibrated. In addition, spiral grooves were created on the roller surface to facilitate the motion of the fruits. The optimal results were roller size 900 × 100 mm (length × diameter), rotation speed 159 RPM, gap size between rollers 4 mm, belt size 850 × 60 mm (length × width), belt pressure 13.5 N, and belt velocity 140 mm/s. Using the design and operational parameters mentioned above, the machine was able to perform regularly at a throughput of 100 kg/h, as demanded by the current market. Moreover, it would be easily feasible to combine multiple pairs of rollers and pressing belts in order to increase throughput. The methodology for the design of this peeling machine and identification of working parameters with respect to experimental data could be applied in many other post-harvesting configurations.

“…The peeling efficiency was observed to be 97-98%. Manjunatha et al, (2012) developed a power operated garlic peeler having cylinder concave mechanism. The cylinder covered with 10 mm thick rubber was fabricated and evaluation was done with cylinder speed (29, 36 and 42 rpm), cylinder concave clearance (8, 10 and 12 mm), moisture content (23.1, 27.7, 33.4 and 40.5% wet basis) and concave mechanisms.…”

Garlic (Allium sativum L.) is one of the most perennial bulb crops of Liliaceae family. It is widely used as a condiment and for medicinal and pharmaceutical preparations. Traditional methods of garlic peeling are laborious, time and cost intensive. The present study was undertaken to develop and evaluate the performance of small capacity garlic peeler so as to overcome the time consumption and cost intensiveness. Engineering properties of garlic relevant to peeler development were identified and measured. It worked on the abrasion principle with very little damage to the cloves after peeling. The peeler was analyzed for its performance at different roller speeds and pretreatment conditions. An evaluation of the performance of the developed peeler with hot air pretreated cloves indicated that it recovered 39.40% of peeled cloves after peeling at 400 rpm of roller speed. For the control samples, maximum peeled clove recovery was 33.45%. The capacity of the machine was found to be 15 kg/h. The maximum peeling efficiency observed was 48.13% with hot air pretreated samples peeled at 400 rpm of roller speed. An economic analysis indicated that the developed garlic peeler could be profitably used for the small scale peeling operations.
