PRODUCT DESCRIPTION
Description
Specifications
The pharmaceutical mixing tank is a specialized vessel, generally constructed of stainless steel. It is designed for precise mixing of liquids, powders and other ingredients (active pharmaceutical ingredients and excipients) to produce uniform, high-quality pharmaceuticals, ointments, suspensions or solutions. Featuring automated agitation, heating/cooling functions and easy-to-clean properties (CIP/COP), it ensures safety, sterility and batch consistency to meet stringent regulatory standards.
-Product Structure
The pharmaceutical mixing tank is made of 316L stainless steel with polished internal surfaces. It is fitted with a heating/cooling jacket and equipped with a motor-driven top-mounted agitator (propeller-type, anchor-type or high-shear type). Sealing is achieved via mechanical seal or packing seal. Additional components include CIP/SIP systems, vent ports, sight glasses, sampling ports and sanitary tri-clamp flanges. All components are engineered for easy cleaning and aseptic operation, complying with rigorous quality standards.

Chemical Mixing Tank : Complete Technical Guide to Design, Applications, Features, and Benefits
Overview
Chemical mixing tanks represent critical process equipment across numerous industries, including pharmaceutical, biotechnology, cosmetic, food & beverage, and chemical manufacturing.
Description
Chemical mixing tanks are essential equipment to achieve thorough blending of chemical substances. Proper mixing guarantees homogeneous distribution of various materials and prevents undesired chemical reactions between components.
Agitation tanks are standard widely-used chemical equipment, available for chemical enterprises of all sizes. The following factors shall be considered when selecting a suitable agitation tank.
How to Select a Chemical Mixing Tank
First, determine tank dimensions based on working volume and available workshop space to achieve neat and unified plant layout.
Second, select tank material according to the medium inside the vessel. Enamel tanks are generally recommended for acidic media, while stainless-steel tanks suit alkaline media. Special materials such as titanium alloy and Hastelloy are also available upon customers’ special requirements.
Third is agitator selection, the most core and technically demanding part of a mixing tank. Agitation style is determined by mixing performance requirements: axial-flow agitation delivers sufficient material blending, dissolution, heat transfer and gas absorption; radial-flow agitation fits dispersion-mixing applications. Agitator power shall be calculated according to tank size, material density, viscosity, solid content, as well as agitator type, impeller diameter and rotational speed.
Fourth is the selection of tank manufacturer. Agitation tank suppliers can be found nationwide with inconsistent product quality and price. Choosing a qualified manufacturer is critical to guarantee one-time qualified delivery.
Main Features of Chemical Mixing Tank
1. Vessel equipped with high-temperature insulating material, anti-aging polyurethane foam or EPE foam.
2. Connections adopt international-standard ISO quick-clamp fittings; liners are made of imported SUS316L or SUS304 Stainless steel. Internal surface is mirror-polished to Ra ≤0.4 μm; external surface options include matte finish, bright polish, matte sandblasting or cool-toned treatment.
3. Agitator sealing adopts imported hygienic mechanical seal or magnetic stirring sealing unit; stirring speed is configurable.
4. Nozzle ports cover connections for level gauges (hydrostatic, capacitive, non-contact ultrasonic, glass-tube type), vent port, thermometer (digital display or pointer type), CIP cleaning port (with or without sight glass), integrated endoscopic lamp (for light-shielding requirement), SIP sterilization port, liquid inlet and hygienic manhole.
