A cocoa seed extractor was produced to increase the productivity of cocoa farmers and reduce the stress and dangers they are exposed to in the process of splitting the cocoa pods and separating the cocoa beans from the pods. The machine has two major chambers: A cocoa seed extractor was produced to increase the productivity of cocoa farmers and reduce the stress and dangers they are exposed to in the process of splitting the cocoa pods and separating the cocoa beans from the cocoa pods, fed into it by the conveyor belt, to crack the pods as they are forced through the centre of rotation. The sprout then conveys the cracked pod to the separating chamber where a rotating beater beats the pod, forcing the cocoa seeds out of it. The seeds then pass through the 16mm sieve in the chamber and are collected at the cocoa seed outlet while the pod is collected at the pods outlet. The machine is powered by a 3 horse power and a 0.74 horse power electric motor. The materials used in its fabrication are locally sourced. A performance evaluation of the machine reveals that it works at an efficiency of 87.5% in terms of the number of cocoa pods processed per day, and at 75% efficiency in terms of the number of cocoa seeds processed without damage. The throughput of the machine is 250kg/hr. Thus, the cocoa seed extractor can process 8,228pods/day compared to about 400pods/day that can be processed by an average person.

However, the high cost and size of plastic crushers have hindered efficient plastic recycling efforts. This research focused on creating a cost-effective, portable plastic crusher tailored for local use. The machine comprises four main units: the feeding, grinding, power, and framework units. A 3D model was crafted using Solid Works software (2017 version 25), and essential components were constructed from mild steel. The feeder has a capacity of 837480 mm 3 , a 20 mm diameter shaft with a power rating of 2.078 kW, and an outlet volume of 748692 mm 3. Performance tests using High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Poly Vinyl Chloride (PVC), and Polyethylene Terephthalate (PET) indicated throughput capacities of 2.83, 2.71, 6.00, and 1.60 kg/h, respectively. The machine has efficiencies of 73.3%, 53.85%, 60%, and 50% for HDPE, LDPE, PVC, and PET, respectively. Notably, the portable plastic grinding machine excels in grinding HDPE, making it highly recommended for small and medium-sized enterprises. This innovation focused on bolstering plastic recycling efforts in localized contexts.
