Yet, Kaolin and its derivatives cost Nigeria around 14 million USD annually, and they have diverse industrial applications such as the manufacturing of paper, ceramics, cosmetics, medicine, paints, and porcelain. This loss of revenue is due to the under-tapping of the mineral due to the absence of beneficiation plants. Currently, the mining is primarily done crudely by artisan miners. Implementing modern manufacturing infrastructure requires adequate attention to cater to facility layout and future improvements, reduce costs, improve customer satisfaction, space utilization, etc. Simulation exercises proffer solutions to these problems in a virtual environment. This work reports a proposed facility layout design for kaolin beneficiation. The proposed plant was designed using Systematic Layout Planning (SLP) methodology and tested using FLEXSIM Simulation software to optimize the plant's production capacity. The results from the design showed that the optimized production plant had an annual production capacity of 95,328 tons, which was higher than the initial layout, with 69,120 tons per annum. The workstations utilization for the optimized layout showed better results than the initial layout design, with the optimized results showing improvements in the efficiency of the workstations as follows (after the simulation): fluid mixer1 had 73.77%, sedimentation tank had 18.44%, rotary drum dryer had 18.44%, packaging line had 63.87%, Screener_washer had 74.46%, and magnetic separator has 63.94% utilization.

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.

Poorly designed facility, therefore, may result in loss in production time, efficiency and wastage of raw materials, while a well-designed production facility improves on the efficiency of production with fewer costs and time wastage (Tak and Yadav, 2012). Among the main goal of manufacturing system is to maximize productivity with regards to the complexity of the processes involved in manufacturing from raw materials to finished products and workstations (Carlo et al., 2013). Agricultural products are processed to among other things improve the shelf-life of the produce and acceptability for final consumption as food or ingredients for industrial production. The output of processing result is varieties of by-products. Vegetables such as onions, tomatoes and pepper are the major vegetables produced in Nigeria, and they play a significant role in health and nutrition due to their constituents that regulate digestion. Onions are processed to produce dehydrated onions, onions powder and puree. Despite the enormous economic potentials of onions, the processing of onions for national growth and development has little to no existence in Nigeria Ibeawuchi et al. (2015). According to Ugonna et al. (2017), Nigeria's vegetable processing industries need to be developed to reduce postharvest losses and enhance food nutrition security. The establishment of these industries will boost the nation's economy thereby creating employment, wealth, reduced rate of malnutrition and increased standards of living for the rural populace. According to Food and Agriculture Organization (FAO) Statistics FAO (2019) it estimated that Nigeria's tomatoes production is around 4.5 tons/ha with annual production of 3.8 million tonnes, while onions production is around 2.3tons/ha, with annual production of 1.3 million tonnes in the year 2019. Despite the huge contributions of agriculture (vegetables) to Nigeria's economic growth, about 50% of fruits and vegetables produced are lost as a result of their perishable nature, poor postharvest handling and mismanagement leading to a staggering 360 million USD losses annually ARTICLE INFORMATION ABSTRACT This study was conducted to determine an effective design for the processing of dehydrated tomatoes. The study proffer solutions to huge losses Nigeria encounters as a result of poor postharvest handling across the fruits and vegetables value chain. Despite the huge contributions of agriculture (vegetables) to Nigeria's economic growth, postharvest losses stands at $9 million with 50% losses in fruits and vegetables as a result of their perishable nature. Systematic layout planning (SLP) approach was used in designing the process layout for dehydrated tomatoes. The design approach was used to serve as an improvement layout and also as a new design for processing of dehydrated tomato plant, with estimated 5% material losses during processing, average temperature for dehydration as 65 o C, plant production time of 748.99 minutes/day, a throughput capacity of 10 tons/day is achievable. Additionally, the design was validated using computer simulation and the results obtained from the simulation analysis indicated that the method can be used to optimize process planning for several production processes of dehydrated fruit and vegetables

This study reviewed some of the key challenges the Nigerian Agricultural sector faces along the agricultural value/supply chains to pave way for the successful implementation of industry 4.0 to some key areas of the sector. INTRODUCTION As the global population grows and technology advances, the demand for effective, fast, reliable, timely production has been a factor of discussions from academia to industry. The Academia focuses on finding concepts, developing systems, methodologies and business models while the Industry focuses on changing the machine dominant manufacturing to an intelligent machines and processes to effect on productivity and increased customer satisfaction [1]. Agriculture was the leading contributor to the Gross Domestic Product (GDP) of Nigeria prior to the discovery of crude oil with 57% to GDP and 64.5% of export earnings from 1960-1969, between 1970-2000 the sector contribution declined to 23.5% and 5.1% as export earnings [2], in 2017 the production increased to 29.15% of GDP while in the second quarter of 2020 it declined to 24.6% as the result of the global pandemic(COVID-19) [3] Nigeria's agriculture potential is high with a population of around 180 million people, an estimated 82 Million Hectares of arable land of which on 34 million is being cultivated, feeding such population is a huge task indeed for the Government and its farmers. The sector is still underutilized as a result of inability to add value to produced products the Country losses an estimated 9 million USD annually to post harvest losses [4, 3]. Some researchers[5] defined Industry 4.0 as an approach that creates an environment in which elements, devices, functionalities are continuously linked together to have a constant communication with a high degree of coordination [5] while other researchers perceived it as a new level of organization and control over an entire value chain of products, increased customer individualization requirements, creates connection of physical systems, internet, designing and drafting production development, integrated approaches, processes and Information Technology driven solutions [6], the author's see it as a collective approach that integrates machines, work schedule and manufacturing systems through integrated networks and value chain to enable constant communication and high level of coordination between each other. The advancement of science and technology dynamically improve on industrialization globally, industrial development have evolved over three stages before the commencement of the fourth industrial revolution [7], these industrial achievements developed over two hundred years ago; the first industrial revolution paved way for steam and water powered facilities, the second gave birth to mass production and assembly systems while the third came with the integration of electronics and information technology (IT) to further automate and simplify manufacturing systems [8] [9].

Nigeria's production of fruits and vegetables is around 16.4 million metric tonnes, which makes Nigeria the 14 th largest producer of tomatoes in the World, 2 nd largest in Africa and sadly the 3 rd largest importer of processed tomato commodities in the World as the result of our inability to refine and add value, Nigeria losses an estimated $9 million to postharvest losses annually. The essence of performing simulation is to experiment and analyse a manufacturing process to reduce the time, cost of procurement of equipment for construction, upgrading and testing the performance in real-life situations. Flexsim software was used to perform simulation runs and optimization alternatives on production lines were drawn, with special emphasis on tomatoes. The simulation was done on the basis of flow chart of the processing of dehydrated fruit and vegetables and design data. Based on the analysis of the simulation data, the study identified the bottlenecks in processing and proffer alternative solutions for improved and optimal output respectively. The Initial model had machine buffer due to the capacity of the dehydrators which made the production to lag by 20% in output stuck as Work-in-process over simulation period. The optimized production line scheme 1 had additional processors for dehydration and milling, it was found suitable for the production process as it addresses the issues of bottlenecks in production with increased production capacity, reduced work-in-process and complete production cycle of 50000 seconds per day.
