In modern industrial manufacturing, the demand for precision, sanitization, and scaling efficiency has transformed the simple storage vessel into an advanced, multi-functional thermodynamic system. For industries dealing with skincare formulations, sterile pharmaceutical suspensions, chemical emulsions, and specialized food products, the mixing tank is the heart of the production line. Modern custom mixing tanks incorporate state-of-the-art technological layers, including high-shear rotor-stator homogenizers, counter-rotating scraper agitators, complex multi-zone thermal jackets, and fully integrated Clean-in-Place (CIP) systems.
As a leading custom mixing tank supplier and factory, SINAEKATO (established in 1992) has spent over three decades mastering the physics of fluid dynamics, solid-liquid dispersion, and micro-emulsification. Our solutions are not generic catalog items; they are custom-engineered systems tailored to address the rheological properties of your specific product—whether it is a low-viscosity liquid wash, an ultra-high viscosity paste, or a delicate lipid nanoparticle suspension.
"True processing efficiency is achieved at the intersection of fluid mechanics, thermodynamic control, and sanitary design. Our engineering philosophy focuses on reducing batch times, ensuring complete particle wet-out, and achieving repeatable formulation characteristics."

Industrial processing requirements differ radically across sectors. A configuration that works perfectly for a cosmetic moisturizer may fail in a pharmaceutical cleanroom or a food processing plant. SINAEKATO designs custom mixing tanks tailored for specific regulatory regimes, rheological behaviors, and sanitization standards.
Skincare formulations rely heavily on stable emulsion creation (droplet sizes under 2.5 microns). Our Vacuum Emulsifying Mixers utilize dynamic bottom/top homogenizers combined with anchor-style wall-scraping paddles to ensure optimal lipid-water integration, eliminating micro-bubbles and achieving a premium gloss and texture in face creams, sunscreen, and body lotions.
Pharma mixing demands absolute sterility and strict documentation. Our custom mixing tanks feature 316L mirror-polished stainless steel (surface roughness Ra < 0.4 μm), orbital welding, zero-dead-leg valves, and comprehensive validation documentation (IQ/OQ/DQ). These vessels are engineered for parenteral drug mixing, topical ointments, and medical syrups.
For high-volume production of shampoos, hand soaps, and body washes, efficiency and foam prevention are critical. Our specialized liquid-washing agitators feature high-torque low-shear blending configurations, dual-action scrapers, and high-speed dispersers that quickly dissolve surfactants and additives without introducing air.
The global manufacturing landscape is characterized by volatile lead times and soaring raw material costs. Operating from our state-of-the-art facility in Gaoyou, Jiangsu Province, SINAEKATO leverages China's advanced industrial ecosystem to offer unmatched supply chain resilience. Our manufacturing base covers over 10,000 square meters of highly automated space, featuring high-precision laser cutters, robotic welding stations, and specialized mechanical and electrochemical polishing lines.
Our vertical integration allows us to keep our pricing highly competitive while maintaining rigorous control over raw materials. Every plate of stainless steel (SS304 or SS316L) is subjected to positive material identification (PMI) testing. Our proximity to key shipping ports like Shanghai and Ningbo ensures rapid, secure transit and reliable delivery schedules for major projects.
By sourcing high-grade components directly from global industry leaders (including Siemens PLCs, ABB motors, Schneider switchgear, and Burgmann mechanical seals), we combine localized component-level resilience with the dependability of internationally recognizable electronic and mechanical platforms. This gives global procurement teams the best of both worlds: highly competitive CAPEX paired with readily available local spare parts.
Over the years, SINAEKATO has secured the trust of leading multinationals, handling complex, high-value customized systems. Our engineering teams work hand-in-hand with procurement officers, corporate engineering divisions, and quality control departments to design processing machinery that fits seamlessly into their existing infrastructure.
Proven Project Execution: In 2018, SINAEKATO designed and deployed an advanced cosmetic processing plant for Unilever in South Africa, completing a custom project valued at approximately USD 800,000. That same year, we partnered with a major OEM manufacturer for SK-II and Shiseido in Japan, delivering high-precision emulsifying machinery worth USD 1,500,000. In 2021, we successfully delivered a USD 1,000,000 liquid detergent washing line for a leading Japanese consumer goods firm.
We support global procurement teams through a structured project lifecycle:
We review product viscosity, shear sensitivity, thermal profiling, and layout limitations to generate detailed 2D/3D CAD layouts and P&ID diagrams.
Every tank and system is dry-run and wet-tested in our factory. Clients can join via physical presence or high-definition live video feeds to audit performance, safety interlocks, and finish quality.
We provide detailed operation manuals, maintenance logs, electrical wiring schematics, and send engineers globally to supervise installation, perform SAT (Site Acceptance Testing), and train local staff.
Operating globally requires strict compliance with localized industrial regulations. SINAEKATO machinery is built to meet and exceed local safety and hygienic codes. Our pressure vessels are designed and fabricated in alignment with global certification standards, including:
Our entire portfolio of vacuum homogenizers, storage tanks, and filling lines carries full CE marking, meeting European health, safety, and environmental protection requirements.
We design our pharmaceutical and cosmetic mixing tanks to integrate seamlessly with strict Good Manufacturing Practices (GMP) frameworks, using sanitary dead-leg-free valves, self-draining piping, and fully mirror-polished contact surfaces.
For operations dealing with volatile ingredients (e.g., alcohol-based perfume blending, solvent-based cosmetic products), we supply custom explosion-proof electrical systems, motors, and control panels certified under Ex/ATEX protocols.
The industrial blending sector is shifting from static, manually operated tanks to dynamic, smart-connected physical units. SINAEKATO is at the forefront of this industrial transition, investing heavily in R&D to build intelligent mixing systems that support smart factory integrations.
By integrating industrial vibration sensors, thermal probes, and power draw monitors on our homogenizers and drive shafts, our systems can detect early signs of mechanical fatigue or seal wear, notifying operators before failures occur.
Modern SINAEKATO control cabinets incorporate PLC setups that automatically adjust agitator speeds, vacuum pressure levels, and steam/cooling water inflow based on real-time feedback of formulation viscosity and heat-up rates.
By optimizing vessel jacket geometry and insulating panels, we reduce heat loss during heating phases. Additionally, our intelligent variable-frequency drives (VFD) cut energy use during low-shear holding stages.

Standard industrial mixing relies on paddles or propellers to disperse raw materials in atmospheric pressure, which often introduces air bubbles and micro-voids into the fluid. Vacuum emulsifying mixers pull a vacuum (down to -0.09 MPa) inside the mixing vessel. This removes air bubbles, prevents product oxidation, and allows high-shear homogenizers to create stable droplets at sub-micron levels, which is crucial for cosmetic creams and pharmaceutical suspensions.
Every stainless steel plate (SS304/SS316L) is subjected to spectral analysis/Positive Material Identification (PMI) prior to machining. Welding is conducted by certified engineers utilizing orbital techniques. All cosmetic and pharmaceutical tanks undergo strict non-destructive testing (NDT), water pressure tests, and surface roughness checks using calibrated profilometers (ensuring Ra < 0.4 μm for contact points).
Yes. Our PLC systems are built using open architecture communication standards (Modbus, Profinet, EtherNet/IP). We regularly integrate our mixing tanks with central SCADA platforms and DCS setups, featuring touchscreen HMIs from Siemens, Omron, or Delta, allowing seamless control of speed, steam, vacuum, and chemical dosing.
A standard 1000L mixing tank with double-jacket heating and anchor agitator requires 30 to 45 days. Complex vacuum emulsifier systems involving hydraulic lift systems, bottom homogenizers, and integrated PLC setups typically require 60 to 75 days. We provide clear timeline schedules during contract execution.
