peeling efficiency, retention of high fruit quality and low energy consumption as well as cost for this method. Mechanical Peeling Mechanical peeling includes different types of process that interact directly with skin and then removes the skin. Common commercial mechanical peelers are abrasive devices, drums, rollers, knives and milling cutters
The process, which works much like an apple peeler, is performed by a doughnut-shaped device equipped with four to six carbide-tipped cutting tools. These spin around and along the cut bar or coil of wire at speeds "substantially faster than is possible with turning," he said. Bar-peeling heads must be carefully adjusted so each insert cuts ...
A disadvantage to abrasive peeling is that in order to achieve peel removal, it takes much more time and much higher yield losses compared to steam peeling. Most often, when peel removal is a requirement for the end product, processors use a hand trimming process to remove the remaining peel that the …
The costs of peeling the Ambarella by machine and manual process were 2.00 LKR/kg and 40.00 LKR/kg, respectively. Machine peeling necessitates 19 times less labour than manual peeling.
ABSTRACT. Peeling is a common unit process for many fruits and vegetables to produce fresh-cut, minimally processed, and canned food products. Mechanical peeling utilizes …
From the review, abrasive peeling is the most employed mechanism of peeling. The peelers were operated at peeling speeds in the range of 40 - 3000 rpm and had peeling efficiencies of 12.7 - 100 %, percentage flesh losses of 0 - 44 % and throughput capacities of 6.2 - 1440 kg/h. ... The peeling process should be commenced as soon as the cassava ...
a) Steam peeling. Steam peeling is carried out either as a batch-wise or a continuous process. Batch-wise the raw materials (roots, tubers) are treated in a pressure vessel and exposed to high-pressure steam (180-200°C). In the case of tomatoes, the temperature may be lower (120-130°C). The high temperature causes a rapid heating and cooking ...
Our abrasive continuous peeling machines have been the global standard for some of the largest food brands for decades. We use that experience to provide high-yield, high-volume scrubbing and peeling solutions to food processors all over the world - from rough scrubbing to finish peeling/polishing for baby carrots and potatoes for French fries ...
The peeling process takes place as a result of the abrasive surfaces of the two metallic drums, rotate in the opposite direction, come in co ntact with the cassava tubers at a required …
diametric size of cassava tubers. The principle of abrasive peeling using a stationary outer abrasive drum and a rotating inn er abrasive drum was used based on a batch capacity of 8.5 kg and cut tuber lengths of 200mm and diameters of 90mm. An average peeling efficiency recorded was 70.45 percent while the average flesh loss was …
The design of two innovative peeling devices, called abrasive pads and abrasive disks, are aimed at evenly peeling the varieties of pumpkin with uneven surfaces (i.e. Jarrahdale and Jap). The performance of the peeling process was evaluated for each method by using the Taguchi method and compared.

Wearing behaviours for abrasive peeling machine under using fresh and stored potatoes. T. Fouda M. Darwesh M. Elkhodarey. Agricultural and Food Sciences. 2020. The aim of this research to study the effect of using fresh and stored potatoes on the wearing behaviours for abrasive peeling drum, The wearing accrue in inner peeling drum were covered ...
Peeling is a significant stage of post-harvest processing of fruits or vegetables. The most adopted peeling methods are mechanical, steam, chemical, and …
Lye peeling involves bathing potatoes in a caustic solution before both the skin and solution are scrubbed off – a method still employed by fruit producers …
The aim of this study is to develop an effective multi-roller abrasive cassava peeling system which will address the problem of tuber flesh loss and to be used in the subsistence and commercial level.
The determination of the optimal technological efficiency of the peeling process, in terms of the number of detached casings and unit costs of the process, is an important task.
PDF | Potato varieties (Hermes and Lady Rosetta) harvested from different type of soil (clay and sandy) were vital …
The effect of a freeze–thaw pre-treatment (FTP) on the peeling process of cassava tubers was investigated in this study. The length and weight of the cassava tubers varied from 200 to 280 mm and 500 to 900 g, respectively. A prototype abrasive cassava peeling machine was used. The operational parameters were the rotational speed of the …
Mechanical peeling using an abrasive-cutter brush is carried out on the basis of applying abrasive and cutting forces. The peeling procedure can be split into two main stages, fracturing of the skin and scratching to remove the peel as formed chips. These operations are the main energy expenditures in this process.
The process of manual peeling was identified as the main source of postharvest loss during small-scale processing of gari, resulting in about 13.90 (±1.26) % loss of fresh cassava which can ...

Mechanical peeling process using an abrasive-cutter brush which applies both abrasive a nd cutting forces was modeled. Choosing the input and output variables which would be industria lly applicable was attempted. Three variables, namely, angular velocities of abrasive-c utter brush ( ωp), the degree of unevenness of produce surface ( φ), and ...
The main mechanisms of peeling process involve formation of ice crystals during freezing, and then thawing results in the rupture of the epidermal cell structure …
