III. Technical Parameters: 

The excellent performance of the hygienic vertical storage tank comes from every precisely controlled technical parameter. From material and volume to sealing and cleaning, every detail has been strictly calculated and optimized to ensure that the equipment adapts to the production needs of different industries, while taking into account safety, efficiency and compliance. The following are the general core technical parameters, which can be flexibly adjusted according to customer needs:

Note: The above are general parameters. For special materials (such as highly corrosive, high viscosity, and easily oxidizable materials), the material, sealing, structure and other parameters can be customized and optimized to ensure that the equipment is perfectly adapted to the production working conditions.

IV. Structural Design

The structural design of the hygienic vertical storage tank always centers on three core principles: "hygiene first, efficiency and convenience, and safety and stability". Every structural part has undergone repeated optimization, which not only meets the strict requirements of clean production, but also takes into account production efficiency and operational convenience, achieving the dual goals of "aesthetics and sturdiness".

1. Tank Structure: Adopting a vertical cylindrical design without sharp edges or angles, the transition section of the inner wall adopts an arc transition, which completely eliminates hygiene dead corners and avoids material residue and bacterial growth (a hygienic stirring device can be equipped as required).

2. Material and Surface Treatment: The tank body, inner tank and all components in contact with materials are made of SUS304 or SUS316L stainless steel, complying with the hygiene standards of the food and pharmaceutical industries. The inner surface adopts electrolytic mirror polishing technology, and the outer surface can be polished, sandblasted, frosted or cold-rolled matte treated according to requirements.

3. Sealing and Interface Design: It adopts a fully sealed structural design. The top of the tank is equipped with a hygienic breather valve and a sealing cover, which can effectively isolate external dust and various bacteria, balance the pressure inside the tank, and avoid material oxidation and deterioration. In addition, accessories such as liquid level gauges, thermometers, pressure gauges and safety valves can be equipped as required to realize real-time monitoring and safety protection of material storage.

4. Optimization of Auxiliary Structures: The bottom of the tank adopts a gradient design, which facilitates the complete discharge of materials without residue and avoids material waste; it is equipped with stable legs or lugs, and the bottom of the legs is provided with anti-slip and shock-absorbing pads to ensure stable operation of the equipment. For scenarios requiring thermal insulation, an insulation layer will be added outside the tank body, using polyurethane or rock wool insulation materials to effectively maintain the stable temperature of the materials in the tank and reduce energy loss; for working conditions requiring heating or cooling, a jacket structure can be added to realize temperature control of the materials.四、结构设计：

VIII. Product Overview:

Q: Can the hygienic vertical storage tank be customized according to the workshop space and material characteristics?

A: Yes. It can be customized in terms of tank volume, height, diameter (to adapt to workshop vertical space), and surface treatment (outer surface polishing/sandblasting, etc.). For special material storage needs, it can be equipped with a stirring device, jacket heating/cooling structure, or insulation layer; accessories such as liquid level gauge and pressure gauge can also be added as required.

Q: How to ensure that there is no material residue during use?

A: The tank adopts a vertical cylindrical design with arc transition at the inner wall (no dead corners), and the bottom is gradient-designed to facilitate complete discharge of materials. In addition, the inner surface is electrolytic mirror polished (Ra≤0.4μm), which reduces material adhesion; regular online cleaning (through CIP interface) can also avoid residue accumulation.

Q: How to use the CIP cleaning interface for online cleaning?

A: Connect the CIP cleaning equipment to the tank's CIP interface, set the cleaning parameters (temperature, cleaning time, cleaning agent concentration) according to the material characteristics, and start the online cleaning program. No manual disassembly is required during the whole process, which can effectively clean the inner tank and avoid secondary pollution.

Q: What is the daily maintenance method of the tank?

A: ① Daily: Wipe the outer surface to keep it clean, check the sealing cover and breather valve for tightness, and ensure that the accessories (liquid level gauge, pressure gauge) work normally; ② Regularly: Clean the inner tank through CIP interface (frequency depends on material characteristics, generally 1-2 times a week), check the anti-slip and shock-absorbing pads of the legs, and tighten loose fasteners; ③ Long-term non-use: Empty the tank, clean and dry it, and seal the inlet and outlet to prevent dust and moisture from entering.

Q: Can the tank be used for high-temperature or low-temperature material storage?

A: Yes. The SUS304/SUS316L stainless steel has good high-temperature and low-temperature resistance. For high-temperature materials, a jacket heating structure can be added; for low-temperature materials, an insulation layer or jacket cooling structure can be configured to maintain the stable temperature of the materials and ensure storage safety.
