Full-flip-cover with hand-cranked worm-gear box (no auxiliary power, smooth operation, self-locking at any angle)
Torsion-spring assisted small flip-cover with explosion-proof light (36V magnetic-delay, Ex dIICT6/IP66) and sight glass with wiper
Flat-base structure — operating platform serves as working surface, no foundation needed
Four-point high-viscosity liquid-damped vibration isolation
All-316L stainless drum machined from solid billet (no hoop), drum welds 100% X-ray NDT inspected and dynamic balanced
Drum flat bottom with no reinforcing hoop — eliminates hygienic dead corners, easy cleaning; flat bottom leaves enough space for hand-wiping
Independent cast-steel bearing housing — inner+outer race design, vertical lift-out for easy disassembly
Double O-ring seal (PTFE-encapsulated) at top of main shaft; static O-ring + skeleton FKM oil seal at bottom
VFD start, energy-recovery brake (≥100s), anti-static narrow V-belt drive
Food-grade lubrication grease
Surface finish: contact Ra ≤0.4, non-contact Ra ≤0.8; all transition joints smooth and radiused
Full safety interlocks: cover-open, over-vibration, motor over-temp/overload, phase-loss, phase-sequence, leakage, e-stop, grounding, cover anti-drop lock
Field explosion-proof operation box (Ex deIICT6, IP65) with speed buttons, indicators, e-stop and audio/visual alarm
Main control cabinet (IP40, carbon steel powder-coat) in control room
Connection nozzles: feed DN40, wash DN20, nitrogen D16, vent DN50, drain DN65; light/sight φ130×10
Design conditions: -10~80°C, -100~500mbar, wash liquid ≥2bar
