Performance evaluation of a mango stone decorticator

Abstract

Purpose

In Nigeria, the mango fruits consumption rate is high during its peak period and this has always resulted in environmental sanitation problem because the mango seeds are thrown to the surroundings immediately the fruits are eaten. Finding more useful application of the kernel would be a way to reduce the environmental pollution. Mechanical decortication of the leathery mango stone remains the only viable option that can support any prospected commercial uses of the mango kernel.

Design/methodology/approach

The decorticator consists of a hopper, a decorticating chamber, spiked shaft, screen shaker and discharge spout. The machine performance was evaluated in terms of decorticating efficiency, mechanical damage and sieve loss.

Findings

Results of the evaluation show that the optimum performance of the decorticator was at a speed of 900rpm, feed rate of 250kg/h and power requirement of 2.50kW.

Originality/value

Mango stones are useful as substitute for maize in finishing broiler diets. The kernel is also used for medicinal purposes in moderation of anti‐bacterial and anti‐fungal activities. Therefore, the designed mango stone decorticator enhances the complete mechanization processes of mango products.
