High-Pressure Extraction Tank Lid
High-Pressure Extraction Tank Lid is a heavy-duty, sanitary top cover designed for closed-loop extraction tanks and industrial pressure extraction systems. Manufactured from premium SS304/SS316L stainless steel, this tri-clamp tank lid delivers reliable pressure resistance, airtight sealing, and high-purity performance for botanical, chemical, pharmaceutical, and cosmetic extraction processes.
Engineered to meet ASME pressure vessel guidelines and sanitary industry standards, our high-pressure extraction lids support stable operation under 1.5–3 bar working pressure and withstand temperatures from -20°C to 135°C. The domed reinforced structure effectively avoids deformation under high pressure, ensuring zero leakage during high-temperature and high-pressure extraction cycles.
Features
- Custom multi-port integrated design to match unique client workflows. The number, position, diameter and connection type of nozzles can be fully customized. Mixed tri-clamp, threaded and welded ports are available to realize feeding, discharging, sampling, pressure monitoring and venting all on one lid.
- Dual lining options of PTFE and PFA for different extraction media. PTFE provides reliable corrosion resistance and cost-effectiveness for routine corrosive fluids. PFA offers ultra-smooth surface, high temperature tolerance and low material adhesion, preventing extract residue buildup for high-purity extraction processes.
- Full fluorine lining on all wetted zones separates corrosive media completely from the stainless steel substrate. It avoids chemical attack and metal ion leaching, protecting both the vessel lid and product purity during long-cycle extraction.
- Heavy-duty CNC machined plate structure for high pressure service. Thickened stainless steel plate with optimized stress distribution, precisely machined sealing groove, ensures stable sealing and structural safety under rated working pressure.
- Hygienic fluoroplastic lining supports complete CIP/SIP cleaning. Smooth liner surface reduces material clinging and dead corners, enabling full drainage and thorough online cleaning and sterilization between batches.
- Flexible customization capability for special specifications. We can adjust plate diameter, port elevation, sealing structure and material grade to fit different tank bodies, pressure ratings and installation space requirements.
Working Principle
This high-pressure extraction tank lid serves as the top sealed closure of the extraction vessel. When the tank runs under pressurized extraction conditions, the flange surface of the lid forms a reliable static seal with the tank body. All process ports integrated on the lid connect to respective pipelines and instruments. The PTFE or PFA lining covers the wetted bore of every nozzle and inner plate surface, isolating corrosive extraction solvent from the metal substrate. Materials, solvent, inert gas or pressure can be introduced or discharged through different ports to complete pressurized extraction, sampling and pressure relief. The integral heavy plate bears internal pressure, maintaining a fully enclosed pressure environment for the extraction reaction.
