Limult Sorghum Processing Factory

Sorghum Processing Technology

Processing of sorghum entails applying suitable grain, milling and malting procedures, which will not only maintain nutritional value, but also lead to minimal grain losses with improved marketability of the end products. The process goes through primary processing which involves cleaning, dehulling (decorticating), pounding and milling. Then comes the secondary processing, which involves turning material into food, i.e. cooking, blending, fermentation and roasting. Both traditional and industrial processing methods are employed, which may involve the partial or complete separation and/or modification of the three major constituents of the cereal grain, i.e. the germ, the starch-containing endosperm and the protective pericarp (or Testa). Industrial methods of processing sorghum though not well developed as that of other cereals have had significant impact on the food security of the country. Industrial processing is inmost cases, geared towards production of grit, malt, meal/flour and sometimes germ, with bran and germ-cake as by-product for feeding animals. Two main methods usually employed in sorghum processing are dry-milling and wet-milling.

Cleaning In traditional systems, grain cleaning is achieved by winnowing, while washing in water will remove most dust and stones. In mechanized systems, forced air (aspiration) is used to remove lighter materials, while most stones, dust and other material are removed as the grain passes over a series of screens. Ferrous metal are removed by a permanent magnet placed in the flow path of the grain.

Small Scale Dry milling of Sorghum The production of virtually all sorghum foods first comprise of two major operations: 1)Debranning (dehulling)- removal of the unpalatable, sometimes tannin-rich and highly pigmented bran and the rancidity causing fat-rich germ; 2) Size reduction (grinding)-converting the endosperm into meal or flour. Traditionally in Africa, sorghum milling has been done using a pestle and mortar for dehulling and saddle quern for grinding or size reducing the grain, methods still used in many African communities. Today, mechanized milling is becoming the norm, creating a milling industry and the opportunity for manufacture of more versatile sorghum food products to meet growing world food demands. Probably the most common method of mechanized sorghum milling in Africanis by abrasive debranning (also known as decortication or dehulling), followed by hammer milling of the endosperm material.

Limult Rice Processing Factory

Rice is the most economically important food crop in many developing countries and has also become a major crop in many developed countries where its consumption has increased considerably. It has become necessary to meet the demand of the world’s current population growth rate, and the least costly means for achieving this aim is to increase rice productivity, wherever possible. The main challenges encountered by rice processors in Nigeria are to find appropriate solutions for quality rice processing. 

In Nigeria, rice consumption has risen tremendously at about 10% per annum due to changing consumer preferences. However, discovered that most Nigerians prefer to consume imported rice brands as compared to local rice varieties. The reason is that most Nigerian rice processors lack adequate technology of rice processing to meet international standard.

Rice processing involves several steps: removal of the husks, milling the shelled rice to remove the bran layer, and an additional whitening step to meet market expectations for appearance of the rice kernels. This process generated several streams of material which include the husks, the bran, and the milled rice kernel. Nigeria has the potential to be self-sufficient in rice production, both for food and industrial raw material needs and for export purpose. However, a number of constraints have been identified as limiting factors to rice production. These include problems with research, pest and disease management. Addressing at least most of these problems is good first step towards attaining the target of rice self-sufficiency.
