Explosion-Proof Mixing Tank

The blending tank, also known as a preparation tank or formulation tank, is a mixing and agitation vessel used to blend one or more materials according to a specific process ratio. The manufactured blending tanks are modern GMP-standard equipment, produced and inspected in compliance with pharmaceutical-grade hygiene standards for the pharmaceutical industry.

The mixing tanks are primarily used in industries such as dairy, chemical processing, food, beverages, pharmaceuticals, and medicine—with the pharmaceutical sector seeing the most extensive application.

Depending on their specific use, blending tanks go by different names. In pharmaceutical liquid preparation systems, they’re commonly referred to as blending tanks, concentrated-blending tanks, dilute-blending tanks, stainless steel blending tanks, sanitary-grade blending tanks, injection-blending tanks, and pharmaceutical-grade sanitary blending tanks, among others. In the food and dairy industries, they may be called blending tanks, formulation tanks, or even sterile blending tanks. Based on volume, blending tanks are categorized into laboratory-sized tanks, pilot-scale tanks, and large-capacity tanks. Additionally, they can be classified according to mobility—into fixed and mobile models—and some are even designed as disassemblable units. Furthermore, blending tanks differ in their stirring mechanisms, including magnetic-stirred tanks and those equipped with impeller blades. There are also buffer-type blending tanks available. Finally, depending on their structural design, blending tanks can be divided into single-layer models, insulated and stirred tanks, and three-layer insulated blending tanks.

The liquid preparation tank features a rational design and advanced manufacturing processes, fully meeting the national GMP certification requirements. The tank body adopts a vertical double-layer structure, with the inner liner polished to a precision of Ra ≤ 0.45. The inner cylinder is equipped with a spiral heating element wrapped around it, and the tank is insulated using polyurethane material for optimal thermal performance. The exterior is finished with either mirror-polished or matte-finished panels, ensuring uniform gloss across the entire surface. All components that come into contact with the pharmaceutical solution are made from 316L stainless steel, while other parts are crafted from 304-grade material. At the bottom of the inner tank, an irregularly shaped head is used, paired with a偏壁式 (eccentric) axial-flow agitator. On the tank’s top, there are inlet ports, reflux outlets, sterilization ports, cleaning balls, manhole filler openings, and a breather valve fitted with a 0.22µm air filter. Additionally, the tank is equipped with a complete mixing system. At the bottom of the tank, you’ll find condensate outlets, discharge ports, drain valves, sampling ports, temperature probes, and liquid-level sensors. A control cabinet is provided for operation, featuring instruments that display real-time temperature and liquid-level data, along with upper and lower limit alarm functions. Furthermore, upon request, the dilution tank can be customized with additional features such as a nitrogen-inflation system and a pH meter.
