| This research work involves the design and fabrication of Irvingia nut cracking machines. It operates using impact technique which involves collision between the seednut and stationary wall. The procedures employed the design stage, fabrication and testing. The machine components are: impact drum, shaft, impeller (rotor), electric motor, driver and driven pulley and hopper. The cracking chamber consists of the impeller and impact drum. The seednuts were pre-treated before testing by sun-drying to improve its crackability. The machine gave a better performance at the speed of 2600 revolution per minute with average cracking efficiency, percentage kernel breakage and capacity of 88%, 17.5% and 916 nuts/hr. The improvement in the design can be achieved by... |

| The kernel of the cutia nut (castanha-de-cutia, Couepia edulis (Prance) Prance) of the western Amazon, which is consumed by the local population, has traditionally been extracted from the nut with a machete, a dangerous procedure that only produces kernels cut in half. A shelling off machine prototype, which produces whole kernels without serious risks to its operator, is described and tested. The machine makes a circular cut in the central part of the fruit shell, perpendicular to its main axis. Three ways of conditioning the fruits before cutting were compared: (1) control; (2) oven drying immediately prior to cutting; (3) oven drying, followed by a 24-hour interval before cutting. The time needed to extract and separate the kernel from the endocarp and... |

| The castanheira-do-gurguéia is a native fruit tree with great regional importance, whose almond present pleasant flavor and exploration still limited. The objective of this research was to evaluate the physical and chemical-nutritional characteristics of 23 castanheira-do-gurguéia genotypes from natural occurrence areas of Piauí State southwestern savannah. A sample of 30 to 50 fruits per genotype was collected. The physical characteristics analyzed were: fruit mass, pericarp mass, fruit length, larger fruit thickness, fruit length/larger fruit thickness ratio, smaller fruit thickness, fruit length/smaller fruit thickness ratio, larger pericarp thickness, smaller pericarp thickness, longitudinal diameter of the pericarp cavity, vertical diameter of the... |
