Loss in Milling.—The normal loss in milling should not exceed \\ to 2 per cent if the maize is good, sound, and dry; this loss is due to cleaning and evaporation during the milling process. From 3 to 1 2\ per cent of bran is extracted when making "sifted mielie-meal," according to the system employed ( the emery-stone or the roller process), the degree of fineness in dressing, and the kind of maize which is milled. In South Africa, a bag of mielie meal usually weighs 183 lbs. TITUS IMPROVED DEGERMINATOR &^^iz*&fy*%m&w. Fig. 221.—Improved degerminator. 595. Samp. — Another mill product largely used is known as samp, the manufacture of which has increased rapidly in South Africa during the last few years. Owing to the excep- tional suitability of the South African types of maize (such as Iowa Silver-mine, Ladysmith, and Hickory King) for the manu- facture of samp, and the adoption of the American system of manufacture and types of machinery, South African millers have practically ousted the American product from the local market. For samp making, the grain is cleaned by the same process employed before milling, as described above (If 590). But a different manufacturing plant is required. This consists of a degerminator (Fig. 221) which removes the bran-skin and "germ" ( the embyro), and breaks the grain into coarse particles. After passing throu
