Cassava Chip Production for Animal Feed
Animal feed has always been a major limiting factor in the growth of the livestock industry in developing countries as most of the feed ingredients are always imported thereby making a large proportion of foreign exchange to be spent for this purpose.
Today, we are going to discuss the unit operations in the production processes of cassava chips, pellets and feed grade single cell protein from cassava roots and by-products, together with the current research efforts to improve these processes.
Small farmers choose to process cassava into cassava chips for animal feed in form of cassava chips, pellets and feed grade single protein. The cassava plant which is made up of the roots, leaves and the stem is a very good source of carbohydrate and protein.
The different parts of the plant can also be used as animal feed, the cassava roots can be chipped and pelletized and used as feed while the root peel, broken roots, fiber and baggage from cassava starch processing can be dried and used directly as animal feed or as a substrate for single cell protein production.
Processing cassava into cassava chips for animal feed is increasing in importance in the developing countries of Latin America and Asia where an export market for this commodity is developed. The European Economic Community imports about 6million tones of cassava annually in the form of pellets or granules.
Step 1: Cassava Harvesting: Harvest matured cassava from the farm.
Step 2: Peel and wash the cassava, this can be done manually or using a cassava peeler.
Step 3: Cassava Chipping: in many households, chipping is usually done manually by hand or by a simple machine which consists of a driven disc with radial chipping slots fitted with cutting blades.
Step 4: Cassava chips drying: this can be classified based on the cost and the technological level of the farmer.
Natural drying, one of the methods used in cassava chips drying is done on cemented floors which are sometimes painted black for better absorption of radiant energy or on trays for artificial drying.
In artificial heat dryers, all these parameters can be optimized to minimize the drying time and guarantee a high quality product.
Now I hope with all the information’s above, you can now start to process your own cassava chips for your animal feeds or even for exports and make more money from there.
