PROJECT DETAIL: Flash dryer
Following are the details of the project:
Nigeria is the largest producer of cassava in the world, with an estimated annual production of 34 Million tones. However, the cassava produced is virtually consumed locally, with little left for industrial processing. In order to stimulate investment in cassava processing, the Federal Government in 2005 introduced a policy mandating flour and confectionery companies to include 10% High Quality Cassava Flour (HQCF) in bread and other confectionery products. The 10% inclusion translates to 320, 000 tons per annum of HQCF. The major challenge militating against the achievement of the target was lack of requisite process technology for producing HQCF using flash dryer and the imported flash dryers are expensive and costly to maintain.
Also, the Federal Government policy on production of 10% Cassava wheat flour composite for bread and other confectioneries created a wide demand gap in HQCF. In order to address this challenge, RMRDC in collaboration with the International Institute for Tropical Agriculture(IITA), Ibadan, Root and Tuber Expansion Programme (RTEP), Umudike, and a private sector farmer, Godilogo Farms in Obudu designed and fabricated a 3 tons/day flash dryer for the production of High Quality Cassava flour (HQCF). The dryer has been commissioned and patented and is currently in use at Godilogo Farms in Obudu Cross Rivers State. It is worthy of note that the whole plant was fabricated at Godilogo, with the exception of the electric motors and the pressure jet diesel oil burner. Also, the Council’s CAPED software was successfully tested in the design of the dryer’s air Cyclone. It is important to mention that a small HQCF processing SME has the potential to employ 25 factory workers to achieve 3tons/day of production.
Notable advantages of the dryer over other dryers in the market include;
- Diesel fuel consumption of 11.5 litres/hour compared to other Dryers that Consume 15-18 litres/ hour of Diesel, thereby saving cost of about ₦1,105.00/hour.
- Total Developmental Cost of the Project is approximately ₦45m as compared to the same capacity of the plant from Brazil at $0.3m -$0.5m and £4m from the U.K
- Better Drying Characteristics than other dryers
- A very low total plant power consumption of 3.5KW was achieved as compared to most plants with power consumption of 18- 50 KW. Saving ₦4,500.00/day
- Automatic plant control, which is responsible for the small variations in product moisture
