“…Critical to the design of rotary roasters are the parameters of optimum roasting time and temperature, which hinge upon the moisture content and nature of the material being processed [12]. An excessive moisture content necessitates extended roasting durations, while maintaining optimal temperatures is essential for achieving efficient convective heat transfer to the drum.…”

The burgeoning interest in maggot-based feed necessitates cost-effective production methods. Traditional roasting techniques for converting fresh maggots into fish feed pellets, predominantly reliant on liquefied petroleum gas (LPG) burners, impose substantial operational costs. Addressing this challenge, the current study introduces a biomass-fueled roasting machine, engineered to reduce energy expenditure and enhance environmental sustainability. Fabricated in a Yogyakarta-based workshop, the ecofriendly roaster features a stainless steel rotary drum (500 mm diameter, 1000 mm length, 3 mm thickness) actuated by a 2 HP electric motor at 28 rotations per minute. The machine's performance was evaluated through temperature profiling, roasting rate, useful heat generation, specific energy consumption (SEC), and overall effectiveness. These parameters were assessed during the roasting of 10 kg and 30 kg batches of fresh maggots over a two-hour period, utilizing teak firewood as the biomass energy source. The empirical findings indicated an optimized performance at the 30 kg capacity, with a roasting rate of 2.86 g/s, useful heat delivery of 62168.30 kJ, an effectiveness of 0.69, and an SEC of 12798.78 kJ/kg water evaporated. The introduction of this roasting machine not only simplifies the maggot pellet production process but also diminishes investment costs. More critically, it encourages the utilization of biomass waste, slashes operational expenses for maggot farmers, and aligns with the principles of sustainable agriculture. This study underscores the potential of integrating biomass-based technologies within the aquaculture feed industry, promoting both economic and environmental benefits.

“…This issue is made worse by the poor local roads, inadequate networks, and in available transport infrastructure services, all of which contribute to the high transport costs in the shea nut supply chain. It is believed that approximately 900,000 women in Northern Ghana are involved in various shea operations and that over two million people depend directly or indirectly on the shea sector for their means of sustenance (Tulashie, Appiah, Akpari & Saabome, 2020). The implication is that any improvement in the shea nut industry is very relevant not only to the industry but to the economy of Ghana in general.…”

Transportation is one of the most important functions of logistics management because of its impact on both the level of customer service provision and the organization’s cost structure. The study explores the transportation cost optimization strategies and how they affect the supply chain performance of Shea nuts in the Agro-processing industries in Ghana. The quantitative study design was adopted and utilized to solicit data. With a sample size of 204 respondents. Data was analyzed using multiple linear regression in Statistical Package for Social Sciences (SPSS v20). The results revealed interesting findings in the supply chain within the institution as it seeks to assert that transportation is seen to be effective and contribute highly to firms output when Agro companies use outsourcing and pooling as means of transport. From the results, the supply chain correlated positively and significantly with outsourcing and pooling as transport optimization practices in Agro firms supply chain. This paper adds to the existing literature on the supply chain systems of Agro processing firms but departs from previous studies which seek to concentrate not on the transport optimization of the Agro processing firms but rather on the challenges, production, and profit maximization of these firms. Our study is unique unlike any other research previously authored as it seeks to reveal the option of transport optimization that is cost effective and efficiently productive for Agro processing firms to adopt.

“…There are international regulations regarding the 5% inclusion of non-cocoa butter in most food industries and other industries requiring cocoa butter equivalent (CBE) oil as key ingredients for their production, this regulation consumes about 90% of shea butter exports from West (Africa Akinsokeji et al, 2017). While Nigeria is among the leading producers of shea nuts in Africa with a production of around 650,000 tons per annum, most of the shea butter produced in Nigeria is not up to export standards of quality due to a lack of modern technology and traditional extraction methods (Tulashie et al, 2020;Akinsokeji et al, 2017). Simulation enables a hitch-free investigation of manufacturing processes and proffers cost-effective solutions for improved decisionmaking on a system for real-life implementation Peng (2011).…”

Manufacturing facilities are systems that require adequate designing, maintenance and reservations for improvement in the future. Layouts need to be effectively designed to reduce operating to the minimum. Computer simulation is a process of investigating and analyzing the behavior of production processes for effective decision-making using computers to generate solutions that will positively impact short, and long-term planning of the Plants and save costs of real-life implementation. This study investigated a 500Kg capacity shea nut processing plant using FlexSim©. The findings from the initial model were not effective and experienced bottlenecks in workstations (Roaster and Milling) sections, poor cycle and lead times coupled with manual labor, Plant efficiency was 35.7%. However, the Improvement Layout Model was able to address these bottlenecks, the results showed the Plant efficiency increased to 83.3%, shorter lead and cycle times, improved machine utilization, and throughput capacity of the Plant. The results were an indication of conformance to the layout design developed to aid in enhancing the traditional shea nut processing that is largely dominated by traditional processing practices.
