Sanitary storage tanks are manufactured by our company in accordance with international quality standards. The tank and liner materials are all made of SUS316L or SUS304 stainless steel. The inner surface of the tank is mirror polished, with a roughness Ra≤0.4μm, and the outer insulation wall is made of SUS316L or SUS304 stainless steel. It is widely used in normal temperature storage or frozen storage of liquid or gaseous materials in pharmaceutical, food, chemical, biological products and other industries. It can be used to store extracts, ethanol, acids, alkali, gases, etc.
1. Classification of sanitary storage tanks

Sanitary storage tanks are classified by form: they can be divided into vertical stainless steel sanitary storage tanks, horizontal stainless steel sanitary storage tanks; classified by pressure requirements: stainless steel pressure vessels, non-stainless steel pressure vessels.

According to the structure, it can be divided into: single-layer storage tank, double-layer storage tank (with insulation layer), three-layer storage tank (with insulation and jacket)

II. Composition of sanitary storage tanks

Hygienic storage tanks are mainly composed of the tank body and accessories.

Sanitary storage tanks are mainly composed of cylinders, legs (or ears), upper and lower heads, jackets and insulation layers. The cylinder of the sanitary storage tank is cylindrical, and the upper and lower heads are standard oval or butterfly heads. The main material is 304 or 316L stainless steel. Sanitary storage tank insulation materials are mostly polyurethane or rock wool, with a thickness of 50mm~100mm.

Sanitary storage tank accessories mainly include sanitary manholes, sight glasses and sight lights, liquid inlets and outlets and other process pipe ports, CIP cleaning ports, and other options such as: liquid level gauge, thermometer, cleaning ball, respirator, and weighing module , pressure gauge, safety valve, etc.

All parts of sanitary storage tanks that come into contact with liquid medicine are made of 304 or 316L stainless steel, which is non-toxic, non-shedding, and has good corrosion resistance. It not only ensures the quality of medicines and food, but also has a long service life of the equipment.

3. Performance characteristics of sanitary storage tanks

1. Operation performance

The accessories of sanitary storage tanks (such as manholes, inlets and outlets, liquid level gauges, breathing valves, etc.) are all reasonably distributed, making them easy to observe and operate.

2. Hygienic performance

The head of the sanitary storage tank is a standard elliptical or dish-shaped form, and the rounded corners are formed by Japanese flat plate hydroforming; the joints of each pipe mouth are drawn to ensure that the corner parts transition smoothly in the form of arcs and the arc radius is ≥10mm ;All welds of the tank are welded by automatic/manual argon arc welding and processed by a stress relief machine; the internal and external surfaces of the equipment are mechanically polished to ensure the internal surface roughness Ra≤0.6μm, which effectively avoids product residue and eases cleaning Difficulty, in line with the requirements of sanitary tanks. The inner surface of the sanitary storage tank is pickled and passivated to enhance the corrosion resistance of the equipment and extend the service life of the equipment.

3. Appearance and performance

The outer surface of the sanitary storage tank is completely frosted by an automatic polishing machine to a matte finish. The polishing texture is uniform and the upper and lower heads are polished to a mirror or matt finish. The roughness Ra≤0.8μm gives people a pleasing feeling and avoids light pollution. .
