BIOETHANOL – HIGHER PROFIT WITHOUT SHELL<br />

Ethanol that has been made exclusively from biomass (renew-<br />

able carbon carriers) or from the biodegradable fractions of<br />

waste products, and which is destined for use as biofuel or for<br />

alcohol production is referred to as bioethanol. Like conven-<br />

tional alcohol, ethanol is obtained by (alcoholic) fermentation<br />

of sugar with the action of microorganisms, and then purified<br />

by thermal separation processes. The raw materials used are<br />

mostly locally available plants with high contents of sugar or<br />

starch: In Europe, these are wheat and sugar beet. Starch-con-<br />

taining raw materials such as cereals are ground. By means of<br />

enzymatic decomposition, starch is converted into sugar dur-<br />

ing liquefaction /saccharification.<br />

nigeria occupies second place in the ranking of the world's<br />

greatest rice importers. The annual rice consumption amounts<br />

to 3.5 million tons, with about 1.5 million tons being imported.<br />

In recent years, it became more and more obvious that nigeria<br />

is highly dependent on rice-exporting countries and has to put<br />

up with a tremendous price volatility on the global market. As a<br />

consequence, the poorest could no longer afford the drastically<br />

increased prices for rice, which caused considerable tension in<br />

the country. On the other hand, nigeria has sufficient arable<br />

land that could be cultivated for rice production, so that the<br />

country might completely abandon the import of rice. Further-<br />

more, due to poor technical standards in the areas of harvest-<br />

ing, drying, storage, and processing in the rice mills, about 30<br />

to 50 % of the local rice harvest is lost every year.<br />

For the future, the government plans a massive promotion of<br />

local rice cultivation and treatment processes by modernising<br />

technical equipment. For this purpose, large-scale promotion<br />

programmes are provided. For more than 50 years, Schule have<br />

supplied parboiling plants and rice mills to nigeria and other Af-<br />

rican countries. At the moment, a turnkey rice processing plant<br />

In the Verticone shelling machines by Schule, wheat or barley<br />

are shelled prior to grinding, which means the outer shell lay-<br />

ers containing only crude fibres (non-fermentable substances)<br />

are removed. As a consequence, the quantity to be treated in<br />

the thermal separation process is reduced so that less energy<br />

is required for cooking, distillation and drying, which increases<br />

the economic efficiency of the process.<br />

In existing plants, in which for example barley with a shelling<br />

degree of about 10 %, is processed, an increase of 10 to 15 % of<br />

the throughput quantity and a higher efficiency can be achieved<br />

by means of pre-shelling.<br />

NIGERIA – PROMOTION AND DEVELOPMENT OF AGRICULTURAL RESOURCES<br />

with a parboiling plant and a rice mill is being assembled in<br />

the north of nigeria. When the plant was designed, particular<br />

attention was paid to a sturdy design of the machines and to a<br />

control system that is adapted to the local personnel. Economic<br />

efficiency was an important aspect in the project realisation.<br />

This plant is an important contribution to the promotion of the<br />

rice industry. Technically, the plant is able to convert locally cultivated<br />

paddy rice into rice with a final quality comparable to<br />

that of imported rice – without any loss during processing. The<br />

supply of further plants might help processing the available agricultural<br />

resources more gently so that they may contribute to<br />

achieve food security. At present, further orders for the modernisation<br />

/extension of existing Schule rice processing plants<br />

are being processed and will be completed shortly. With their<br />

experience in the fields of drying, cleaning, and parboiling and<br />

rice milling technology, Schule is an important partner for the<br />

nigerian rice industry.<br />
