1500L Stainless Steel (SUS316L) Double Cone Rotary Dryer

Total Equipment Volume: 1500L Working Volume: 750L Loading Weight: 350kg

The vacuum filter head uses three pieces of SUS316L sintered mesh, distributed at a 120º angle, rotating synchronously with the cylinder.

All equipment surfaces in contact with materials shall be made of SUS316L, while all surfaces not in direct contact with pharmaceuticals shall be constructed or clad with high-quality SUS304 stainless steel. The thickness of the external stainless steel cladding shall not be less than δ=2.0mm.

All protruding and recessed parts on both the inner and outer surfaces of the equipment are designed with rounded transitions (R≥10mm) or chamfered transitions at an angle of no less than 135°, ensuring no dead corners and easy cleaning.

The inner surface of the equipment has a polish degree of Ra ≤ 0.4μm, and the outer surface is matte.

The sealing material is pharmaceutical-grade polytetrafluoroethylene.

All welds or solder joints should be polished and passivated. The materials of components and parts shall comply with production, process, and GMP requirements.

The outer surface is smooth, clean, and aesthetically pleasing, with chamfering and rounding at transitions. Bolts and nuts exposed on the equipment's exterior must be capped or covered, and there shall be no obvious dents, burrs, scratches, impacts, or signs of corrosion.

The inspection door should be sealed with pharmaceutical-grade polytetrafluoroethylene (PTFE). Effective sealing should be provided between the drum shaft and the machine guard, as well as between the vacuum pipe, hot water inlet and outlet pipes, and the machine body, to prevent the spread of internally generated foreign matter to the outside.

The equipment structure is reasonable. The feed end of the barrel is equipped with a sanitary manhole, while the discharge end is fitted with a sanitary butterfly valve and quick-install blind plate. The sealing ring is made of food-grade silicone.

Internal design pressure of the cylinder: -0.1MPa to 0.098MPa Jacket design pressure: 0.5MPa

Barrel rotation speed: adjustable from 0 to 10 r/min, currently primarily used for mixing. Should the speed be adjusted to 0 to 15 r/min? Does it require special design? Please provide clear clarification from the manufacturer.

The transmission system consists of: primary belt drive, secondary turbine reducer, and tertiary chain drive. The manufacturer can determine the configuration based on the double-cone form, and the reducer brand should be an imported brand.

The drive shaft and the bearings of each component are critical parts of this equipment. Their material and machining precision must meet the requirements for continuous full-load production of this equipment. Under normal usage conditions, no quality issues shall arise within three years.
