| dc.description.abstract | Nutmeg (Myristica fragrans Houtt.) has been used as natural food flavouring in baked goods, syrups, beverages, savory dishes and sweets. The essential oil obtained from nutmeg is used heavily in the cosmetics and pharmaceutical industries. Nutmeg and Mace are two different parts of same fruit of the nutmeg tree - Myristica fragrans Houtt. The fruits are pendulous, broadly pyriform, yellow, smooth, 7- 10cm long, fleshy splitting open into two halves when ripe, showing the ovoid 2-3cm long dark brown shining seed with hard seed coat, surrounded by a glaciate red aril attached to the base of the seed. The process of decortication of nutmegs to separate kernels is done manually using a hammer or mechanically a cracking device. The traditional decortication process is time and labour consuming. To address this power operated nutmeg decorticator was developed and its performance was evaluated. The developed nutmeg decorticator consisted of a cylinder and a concave. The cylinder was made up of mild steel angle flats of size 24.8×1.9cm and a rubber of thickness 0.5cm was fixed on to these flats to establish impact to the nuts. While the concave was fabricated using 6 mm size M.S. rods. The length of concave was 25cm with slotted opening size of 7.7×1cm. The developed decorticator had the decortication efficiency, total recovery, breakage and capacity of 98.11, 63.92, 3.08 per cent and 56.59 kg/h, respectively, at a cylinder speed 450 rpm. The cost of decorticating 1kg of raw nutmegs at 12% moisture content was ₹ 0.79, only. The cost benefit ratio of the developed decorticator was 1:1.19. | en_US |
