Development and evaluation of a garlic peeling machine

الملخص EN

The main aim of the present study is develop, manufacture and evaluate a garlic peeler which is made from local raw materials.

The effect of different rotational speeds of disk (210, 240 and 270 rpm), operating times (1, 2 and 3 min) and batch loads (0.5, 1.0 and 1.5 kg) were studied.

The peeler productivity, efficiency, damage cloves percentage, specific energy consumption and costs were determined.

The obtained results indicated that the garlic peeler productivity increased from 17.88 to 19.33 and 8.52 to 29.04 kg h^-1, with increasing rotational speed of disk and operating time, respectively and it decreased from 28.84 to 12.46 kg h^-1 with increasing batch load from 0.5 to 1.5 kg.

The peeler efficiency increased with increasing rotational speed of disk, operating time and batch load.

The highest value of damaged cloves percentage (0.26% ) was found for 270 rpm rotational speed of disk at 1 min of operating time for 1.5 batch load.

The specific energy consumption decreases with increasing rotational speed of disk and operating time.

The total cost of garlic peeler decreased from 0.230 to 0.215 and 0.402 to 0.105 EGP kg^-1 with increasing rotational speed of disk and operating time, respectively.
