| Abstract |
This research was carried out at El Mansoura Laboratory of soil fertility in Mansoura sity, Dakahlia Governorate, during 2001 season to mill two garlic cultivers (Balady and Sides-40) after slicing the cloves and drying the slices. The aim of garlic milling is producing garlic powder which is considered as the most effective commercial preparation for securing all health benefits of garlic. To achieve this aim, a laboratory swinging beaters hammer mill powered with a 0.20 kW motor was used. Factors studied were three hammer tip speeds (13.82, 18.43 and 23.04 m/sec), two feeding rates (27.00 and 43.20 kg/h), two screen hole diameters (1 and 2 mm) and two drying methods (natural and artificial). The performance of the mill was evaluated according to the actual milling capacity, milling efficiency, weight reduction ratio, energy requirements and oil content garlic powder.
The obtained results are summarized as follows:
1- The highest milling capacity of 7.10 kg/h was obtained by milling artificially dried garlic sides-40 variety at 23.04 m/sec hammer tip speed, 43.20 kg/h feeding rate and 2 mm screen holes diameter.
2- The highest milling efficiency (99 %) obtained by milling naturally dried garlic balady variety at 13.82 m/sec hammer tip speed, 27.00 kg/h feeding rate and 2 mm screen holes diameter.
3- The least specific milling energy of 39.76 MJ/Ton was obtained by milling artificially drying garlic sides-40 variety at 13.82 m/sec hammer tip speed, 43.20 kg/h feeding rate and 2 mm screen holes diameter.
4- The least specific powder production energy was 46.92 MJ/Ton was obtained by milling artificially dried garlic sides-40 variety at 13.82 m/sec hammer tip speed, 43.20 kg/h feeding rate and 2 mm screen holes diameter.
5- The highest weight reduction ratio of 1.35 was obtained by milling artificially dried garlic sides-40 variety at 23.04 m/sec hammer tip speed, 43.20 kg/h feeding rate and 1 mm screen holes diameter.
6- The highest oil content in garlic powder of 12.51 % was obtained by milling artificially dried garlic sides-40 variety at 23.04 m/sec hammer tip speed, 43.20 kg/h feeding rate and 1 mm screen holes diameter.
Analysis of variance indicated that there was high significant effect on oil content in garlic powder due to the interaction among levels of garlic hardness degree, hammer tip speed and screen holes diameter. The following regression formula represents the relation between oil content in garlic powder (Y), garlic hardness degree (X1), hammer tip speed (X2) and screen holes diameter (X3).
Y = 1.47 + 0.48 X1 + 0.04 X2 - 0.04 X3
