The PSQ flat cover centrifuge components are all made of stainless steel, with all fasteners being stainless steel as well. Both the inner and outer surfaces of the drum and the housing, as well as the cover's inner and outer surfaces, are polished for a smooth, clean finish. The transition between components is seamless and flat, effectively eliminating卫生 blind spots. The housing cover features a large flip cover design and is equipped with a spray washing system for online cleaning of both visible and invisible surfaces of the machine. A nitrogen protection system is configured to isolate the centrifuge interior from external air, meeting the requirements of the production process. The machine employs a sealed structure with silicone or fluororubber seals at the sealing points. Explosion-proof motor, variable frequency drive, and energy-saving brake devices are equipped to meet the enclosed explosion-proof requirements.
