Title: Process for the production of solid milk products
IPC: A23C9/156
Filed: 1939-03-07
Abstract: 526,062. Preserving milk; food preparations. NEDERLANDSCHE GRUYERE-BLOKMELK FABRIEK N.V. March 7, 1939, No. 7433. Convention date, Oct. 7, 1938. [Class 49] A solid product is prepared from milk, or milk enriched with milk fat, by adding cane sugar and monoses, such as pure anhydrous dextrose, which reduce the redox potential to such an extent that the fat is protected against oxidation, and subjecting the mass to gentle evaporation in vacuo, preferably with stirring. The plastic mass thus produced may be moulded into block form and the blocks subsequently reduced to powder which is further dried. Sugar is added so that the sugar content of the evaporated product is from 30 to 70 per cent. by weight. The reducing sugar is from 10 to 15 per cent. of the total sugar or about one-third of the weight of the milk fat. The solubility of the product may be improved by adding to the mass, before evaporation, weakly alkaline salts, preferably salts the ions of which are already present in milk serum, such as secondary sodium phosphate, sodium citrate, sodiumammonia phosphate, in such amounts that the pH value remains below 7. Comminution of the blocks may be effected in a disc mill. To avoid conglomeration of the particles under pressure they may be allowed to fall freely from the grinding apparatus into a drying chamber, and conveyed through the chamber by inert gas. Alternatively the grinding and drying are effected under partial vacuum, for example by sucking the particles directly into and through the drying chamber. The drying is effected at a temperature of about 50‹C. a final water content of 1 to 2 per cent. by weight being attained. The keeping properties of the product are improved by preventing contact, particularly during evaporation, with metals which might promote catalytically the oxidation of milk fat. Apparatus of non-rusting steel or protected by coatings of noble metals, aluminium or enamel, which has no catalytic action, may be used. The milk powder may be mixed with constituents of pudding powders or with coffee, coffee or cocoa extracts &c. for the direct preparation of milk coffee or cocoa &c. Pudding powder may be added during the evaporating step.

Filed: 1917-05-26
Abstract: 112,721. Rogers, F. H., (Eclipse Machine Co.). May 26, 1917. Turning-gear.-The turning-gear is of the hind comprising a screw shaft driven by an electric motor, a pinion mounted on the shaft for longitudinal movement thereon and rotation therewith. and a spring engaged by the pinion at the end of its longitudinal movement for cushioning the shock of starting. In one form, Figs. 3 and 4, a frictional device which imparts resistance to the pinion 27, to cause it to move longitudinally on the screw shaft 26, is relieved of friction by centrifugal action when the pinion rotates. In this form, the shaft 26 is driven by a motor 11, and the pinion 27 moves into engagement with a gear 24 in mesh with a gear on the engine crank-shaft, the movement being cushioned by a collar 28 and a spring 30, Frictional resistance is imparted to the pinion by weighted arms 31, which are held by a spring 32 in contact with a fixed member 39, the friction between the parts 31, 39 being relieved by centrifugal action when the pinion rotates. The arms 31 are enclosed by a ring 34 having lateral arms 35 secured to a collar 36, which is free to rotate between collars 37, 38 on the shaft.26. When the engine starts on its own power, the pinion 27 returns to the position shown in Fig. 4, the aims 35 being moved outwards by centrifugal action and preventing reengagement of the pinion. The motor is then driven as a generator through gearing 24, 22, 17, and pawls 20 engaging a ratchet 19. In a modification, Fig. 9, frictional resistance is imparted to the pinion 42 by a rotatable weight 45 encircling a weight-retainer 44, and having a groove 46 filled with grease. In this form, the movement , of the pinion into mesh with a gear on the crank-shaft is towards the motor. In its retracted position, the pinion is stopped by a pin on the screw shaft. The friction between the weight and retainer may be augmented by a flat spring or a ratchet device.
