Stainless Steel Sanitary Storage Tank for Food Industry

 

 

Sanitary storage tanks have emerged as a cornerstone in the pharmaceutical, food, chemical, and biological products industries, offering unparalleled storage solutions for liquid and gas materials. Constructed from high-quality SUS316L or SUS304 stainless steel for both the tank body and liner, these tanks guarantee durability and corrosion resistance. The inner surface of the tank boasts a mirror polish with a roughness of Ra≤0.4μm, ensuring smooth surfaces that minimize product residue and ease cleaning processes. The outer insulation wall, similarly made of SUS316L or SUS304 stainless steel, provides additional protection and insulation, making these tanks suitable for both normal temperature and frozen storage applications. Whether storing extracts, ethanol, acids, alkalis, gases, or other materials, sanitary storage tanks have become indispensable in maintaining the integrity and purity of stored products.

 

The structural design of sanitary storage tanks is meticulously engineered to meet the diverse needs of various industries. The tanks feature upper and lower heads in elliptical, flat, or cone shapes, equipped with a stirring system for efficient mixing. The cylinder is constructed from S30408 or S31603 stainless steel, ensuring strength and corrosion resistance. The heating system can be configured as a jacket, inner coil, or electric heating, providing flexible temperature control options. Support structures include legs, ears, or a saddle, allowing for stable installation and easy maneuverability. The internal and external surfaces are polished to a roughness of Ra≤0.4μm, maintaining high hygienic standards. A range of accessories enhances functionality, including sanitary manholes, sight glasses, lights, material and liquid inlet and outlet pipes, CIP cleaning ports, and optional features such as liquid level gauges, thermometers, cleaning balls, respirators, weighing modules, pressure gauges, and safety valves. This comprehensive design ensures that sanitary storage tanks are versatile, efficient, and reliable.

 

Sanitary storage tanks excel in their operational, hygienic, and appearance performance. Operationally, the tanks' accessories are strategically placed for easy observation and manipulation, simplifying routine checks and maintenance. The tanks' heads adhere to standard elliptical or disc shapes, with Japanese flat plate hydraulic forming fillets ensuring smooth transitions and arc radii of ≥10mm at all pipe mouth joints. Automatic/manual argon arc welding, coupled with stress relief treatment, guarantees robust welds on the tank body. Mechanical polishing of both inner and outer surfaces maintains the Ra≤0.4μm roughness, preventing product residue and facilitating effortless cleaning. The inner surface undergoes pickling and passivation processes, enhancing corrosion resistance and prolonging equipment lifespan.

 

In terms of hygienic performance, the tank's design minimizes contamination risks. The smooth, arc-transitioned corners and polished surfaces prevent the accumulation of dirt and bacteria, crucial for industries where sanitation is paramount. The pickling and passivation treatment further fortifies the tank's corrosion resistance, maintaining product purity and safety.

 

As for appearance, the tank's outer surface undergoes automatic polishing to achieve a uniform matte finish, with the upper and lower heads polished to a mirror or matte finish, ensuring aesthetic appeal and consistency. The hygienic and stable production process underpins the tank's overall quality and reliability.

 

To facilitate seamless integration and compliance with industry standards, sanitary storage tanks come with a comprehensive suite of technical documents. Equipment drawings in CAD format, installation drawings, product quality certificates, and installation and use instructions are provided with each tank. These documents ensure that users can install, operate, and maintain their tanks with ease and confidence.

 

In addition to these standard documents, the tanks can adhere to various design, production, and inspection standards tailored to user needs. These include the SFDA's "Good Manufacturing Practice for Pharmaceuticals" (2010 Edition), "Pharmaceutical Industry Cleanroom Design Specifications" (GB50457-2008), GAMP Pharmaceutical Production Automation Management Specifications, GB150.1~150.4-2011 "Steel Pressure Vessels," and NB/T47003.1-2009 "Steel Welded Atmospheric Pressure Vessels." Compliance with these standards underscores the tanks' commitment to safety, quality, and performance.

 

Sanitary storage tanks offer flexibility in design and manufacturing to cater to the unique needs of each customer. Tanks ranging from 1000L to 2000OL can be designed and processed according to actual customer specifications, ensuring optimal fit and functionality. The quick-install interface on the tank body adopts the internationally accepted ISO standard quick-install chuck type, facilitating easy installation and integration of accessories such as high-precision liquid level gauges, digital thermometers, tank washers, light sight glasses, manholes, and additional quick-install interfaces.

 

The tank body material, sourced from imported 316L or 304 stainless steel, guarantees robustness and corrosion resistance. The inner surface's mirror polish with Ra≤0.4μm roughness and the outer surface's mirror or matte treatment enhance both functionality and aesthetics. This attention to detail ensures that each tank meets the highest standards of hygiene, durability, and performance.

 

In conclusion, sanitary storage tanks represent a significant advancement in storage solutions for the pharmaceutical, food, chemical, and biological products industries. Their construction from high-quality stainless steel, combined with meticulous polishing and treatment processes, ensures that these tanks meet the highest standards of hygiene, durability, and performance. The comprehensive range of accessories and customizable design options allows for seamless integration into various operational setups, catering to the specific needs of each customer. With technical document support and compliance with industry standards, sanitary storage tanks are poised to revolutionize storage practices, enhancing product safety, purity, and operational efficiency. As industries continue to evolve, the adoption of these advanced storage solutions will be crucial in maintaining high standards of quality and safety, driving innovation and growth in the sector.
