Current Research Projects

I. Completed.

(a) Drying and Sorption Studies on Millet and Castor

There is dearth of information on the drying behaviour of castor while that of millet is limited to sorption of a few varieties. This work examined the moisture sorption and drying behaviour of the crops and found that drying occurred in the falling rate phase with Knudsen flow as the mechanism of moisture movement. These information are useful in the design of efficient drying systems for the crops.

(b) Mathematical Modelling of palm kernel oil expression using Screw press.

This study looked at some of the operational parameters that influence the efficiency of screw press; pressure, feeding rate and speed of rotation. Mathematical model was applied to determine the degree of influence of these parameters on performance of a screw press. Pressure was found to significantly influence oil yield while machine parameters have no influence on the free fatty acid. The use of mathematical model to describe the relationship between process variables and product characteristics encourage experimental design whereby maximum amount of information can be obtained from minimum number of experiments. The mathematical relationships obtained are useful in engineering designs.

(c) Development of a Computer Model for Management of Agricultural Wastes.

A software for determining and selecting appropriate management of waste at commercial level was developed and tested in this study. The model which was developed on a Visual Basic platform as the front-end with an interactive data input and output display screen shows that the algorithm, using appropriate data, is a useful tool in predicting management method for waste. It is also useful in pre-planning ever before the production and generation of waste having known the type of waste. It is therefore a reliable method as it considers all the necessary components and composition of waste in making prediction.

(d) Waste to Wealth: Briquette production from sawdust.

This study involved the development of a machine designed to combine ration of dried and sieved sawdust premixed with cassava starch paste of desired consistency to produce briquettes. The machine compresses the sawdust/starch mixture in moulds and the pressure was kept on the sawdust/starch mixture for a specified period of time. The dried briquettes are high grade products for cooking and heating purposes. The briquetting technology can be commercialized to form the basis of a business venture, thereby contributing to poverty alleviation in the country

(e) Effect of processing methods on the quality of Cassava Pellets.

Processing cassava onto pellets is a means of storage, minimizing quantitative and qualitative losses and obtaining an internationally acceptable and commercially rewarding cassava product. This study produced cassava pellets using three different processes and the samples investigated for storageability and nutritional qualities. The pellets produced from the modified process were better in terms of strength, durability, time of drying, appearance and nutritional quality compared to the cold pellets from the conventional process.

(f) Design of flash dryer for High quality Cassava Flour. A joint research work with IITA/RMRDC/RTEP/GODILOGO.

This study was on the design and fabrication of a new flash dryer by a team of Nigerian Engineers to produce high quality cassava flour from cassava mash. The dryer was constructed and installed at Godilogo Farms Limited and tested under industrial conditions. The energy consumption was found to be very economical with a very high throughput compared to corresponding values obtained from two existing flash dryers when the same cassava mash was used. The quality of the cassava flour produced from the new flash dryer falls within the acceptable Nigerian standards for this product.

II. In Progress

(a) Discrete Element Modelling of Agricultural Particulate Handling.

This research work is currently been extended to handling and transportation of perishable products. Studies have been completed on the storage and handling methods of perishable crops using tomato as a case study. Simulation and model prediction of the damages is now being studied with this method.

(b)Image Processing and Machine Vision in Agricultural Processing Operations.

This study has reached an advanced stage with trial tests on the determination of the leaf area index of cowpea. This is expected to be applied to the detection of damages during handling of agricultural and food materials.

(c) Waste to Health: Production of Medicinal Drugs from Agricultural Waste (Weeds).

This is a Senate Research Grant project that is currently at the level of design and installation of machines for size reduction.

(d)Engineering Properties of Cassava and Cassava Products.

An ongoing study on the effect of age on the engineering properties of cassava tubers and products. This study is expected to result in provision of information useful in machine design for tubers and the products.
