Continuous-discharge apparatus with stationary containers.-Relates to thrashing or high-speed beating-machines for thrashing and beating liquids, preferably in the presence of air, and more particularly for thrashing mixtures of cocoa liquor, sugar, and other ingredients in the manufacture of chocolate fondants. The machine is of the type in which a high-speed rotor works. within a stator, the material being passed through the narrow clearance-space between the rotor and the stator and thrashed or beaten by blades, - pins, projections, or the like on the rotor or stator, or both; or the rotor and stator may be stepped or corrugated. According to the invention, means are provided for admitting water or other fluid to the interior of the rotor, or circulating a current of fluid through it, to control the temperature of the rotor. As shown in Fig. 1,. water is admitted to the hollow rotor 4 through its hollow shaft 3 and extension 37. The water is supplied through a funnel 57 and passes through inlets 58 in the collar 53 to which the rotor is bolted. The water escapes by a pipe 59 into the hollow shaft 3 and is collected in a vessel 60. The extension 37 carries a worm 36 working within the feed-hopper 32. Air is supplied to the liquid under treatment through an inlet 40 in the outer casing 33 of the hopper 32 as described in Specification 166,995. The air may be supplied by a fan or blower and passes through inlets 56 in the casting 20 of the cover-plate 11 of the stator. The space between the two members.20, 21 of the cover-plate is divided into two concentric parts by means of an annulus 55, and the outer space may serve as a heat-jacket. In another arrangement, Fig. 2, water is admitted through a pipe 80 and injected or sprayed through the inlet 81 on to the interior top surface of the rotor 4. The water drains into a trough 82 in the interior of the stator and escapes by an outlet 83. An annular guard 84 prevents the water from reaching the bearings of the shaft 3, and an extension 85 of the vertical wall of the rotor prevents it from reaching the liquid under treatment. The base 6 of the stator to which the trough 82 is secured by bolts 91 is cast in one with the walls of the jacket 15. The invention is particularly applicable to machines of the kind described in Specification 165,844.
