1. Product Overview & Core Purpose
We design a Pharmaceutical Liquid Mixing Tank (also called a blending tank or stirring tank) primarily as a vertical mixing vessel. It achieves process production requirements by agitating materials through the tank’s stirring operation. This equipment acts as a necessary device for intermediate buffering, liquid storage, stirring, blending, and reaction in pharmaceutical, bioengineering, and food production industries.
2. Main Structural Components
A pharmaceutical liquid mixing tank (or vacuum blending tank) typically consists of several key parts:
- Tank body: The main cylinder structure
- Tank cover: Also known as the head
- Heating/cooling system: Jacket or coil for heating/cooling circulation
- Agitation system: Upper mechanical agitator (available in anchor type, paddle type, turbine type, etc.)
- Transmission device: Motor-reducer combination
- Shaft seal device: Mechanical seal for leak prevention
- Supports: Platforms and legs for stability
- Thermal insulation media: For temperature maintenance
The system configuration of the tank mainly includes transmission devices, mechanical seal devices, temperature control devices, cooling devices, as well as weighing and metering devices, and liquid level metering devices.
