APPARATUS FOR SCALING RAW MILK MATERIAL AND TREATING OIL GRAIN Russian patent published in 1996 - IPC

FIELD: milk industry. SUBSTANCE: apparatus has casing 1 with fixed tank 2 and shaft 9 of vortex-type blade mixer. Shaft 9 is positioned in bearing-gland units 4 and 5. Hub 10 with curved beating blades 11 is fixed on shaft 9 and kinematically connected with electric drive. Apparatus has discharge branch pipe 30 and cover 50. Blade mixer has S-shaped section. Profile of each blade 11 has partially parabolic configuration. Radial slots 16 with parallel edges 17 are staggered on blades 11. Ridges 18 positioned in diametrically opposed relation with respect to slots have width exceeding that of slots. L-shaped ridges 19 are positioned adjacent to outer edges 12 of blades 11 proximate their curved surface 14 on both parallel edges 17. One of walls 6 of tank 2 extending in parallel with shaft 9 and tank bottom 8 are positioned at an angle below 90 deg one with respect to the other. Plates 24 and 25 are fixed on wall 6 below the level of raw milk material filling tank 6 adjacent to output side of curved surfaces 14 of blades 11. Planes of plates 24,25 are extending in parallel with planes intersecting with axial line of shaft 9. Inner surfaces of tank 2, hub 10, convex surface 15 of blades 11 and plates 24,25 are made rough. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 8 dwg
