Mrs Helen Adekola's son had malaria and she was advised by a friend to also give him a worm
expeller. Her friend said this would afford the child a quicker recovery from malaria.
Feed intake during the collection period was greater (p<0.05) for the basal, palm kernel
expellers, and TDDG diets than that for the HPDDG and canola meal diets (Table 3).
Depending on the different oil extraction procedures, the copra byproducts can be classified into mechanically extracted copra meal (copra
expellers, CE; IFN 5-01-572; AAFCO, 2016) or solvent extracted copra meal (CM; IFN 5-01-573; AAFCO, 2016).
The last disadvantage of the
expeller gland is that the
expellers are designed to balance the centrifugal pressure generated by the impeller.
Some 9,000 Kohlus (bullock drawn wooden mortar and pestle), 8,500 small and medium sized
expellers and 800 oils mills of all types and sizes are in existence in the country.
The data relate to low-pressure
expellers with input of 100 tons of cottonseed per day, and to high-pressure
expellers, direct-solvent extractors and pre-press extractors with input capacities of 500 tons of cottonseed per day.
Several co-product candidates are oilseed meals such as palm kernel meal, palm kernel
expellers, copra meal, or so on.
3.150 million is being borne by the country in oil extraction industry - cotton seed only - due to use of out-dated and low-grade indigenous
expellers.
Copra
expellers (CE) and palm kernel
expellers (PKE), co-products from vegetable oil industry, are produced by the mechanical oil extraction from dried coconut kernels and palm nut kernels, respectively (Son et al., 2012; Sulabo et al., 2013).
The palm kernel co-products such as palm kernel
expellers and meals are co-products from the kernels of oil palm fruits after oil removal by chemical or mechanical extraction (Sulabo et al., 2013) and contain low energy density, poor amino acids profiles, and high fiber containing relatively high soluble fiber, such as [beta]-mannans and glucomannans that may affect animal gut health (Pluske et al., 2002), compared with conventional feed ingredients (Balasubramaniam, 1976; Daud and Jarvis, 1992; Dusterhoft et al., 1991; NRC, 2012).
Because copra
expellers (CE), palm kernel
expellers (PKE), and cassava root with hulls (CR) are relatively cheap and good sources of nutrients, the increased use of these ingredients is expected (Kim et al., 2001; Son et al., 2012).
So the old 'kohlu' which was a mechanical press used for extracting oil from seeds was gradually replaced by mechanical
expeller presses.
