International Feed Number

The following tables present data on average values of energy and nutrients for a range of feedstuffs likely to be used in organic poultry feeding (as-fed basis). Each feedstuff is listed under its International Feed Number (Harris, 1980), and definitions of the feedstuffs taken from AAFCO (2005) or CFIA (2007).

Distillation columns can be classified according to ve criteria function to be carried out, number of components in the feed, number of streams of products, design pressure in the column, and column internals as shown in Figure 7.2.

The feed must be nonabrasive with a hardness of 1.5 or less. The miU is capable of taking 2-cm ( A-in) feed material, depending on the size of the feed throat, and reducing it to a product substantiaUy aU able to pass a No. 200 sieve. For producing materials in the fine-size range, it may be operated in conjunction with external air classifiers. Such an arrangement is shown in Figs. 20-12 or 20-42. A number of machines have internal air classifiers. 

UK. = Light key component in volatile mixture L/V = Internal reflux ratio L/D = Actual external reflux ratio (L/D) ,in = Minimum external reflux ratio M = Molecular weight of compound Mg = Total mols steam required m = Number of sidestreams above feed, n N = Number of theoretical trays in distillation tower (not including reboiler) at operating finite reflux. For partial condenser system N includes condenser or number theoretical trays or transfer units for a packed tower (VOC calculations) Nb = Number of trays from tray, m, to bottom tray, but not including still or reboiler Nrain = Minimum number of theoretical trays in distillation tower (not including reboiler) at total or infinite reflux. For partial condenser system,... 

The uniform distribution of feed liquor is achieved by the use of a specially engineered distribution pipeline running internally along the base of each compartment and containing a number of carefully designed apertures along its length.
