Main structural features and classification analysis of multifunctional extraction tank

### Key Structural Features of Modern Multifunctional Extractors

1. **Heating Method**:

- Combines jacket and bottom heating to address micro-boiling challenges.

- Bottom heating ensures controlled micro-boiling, improving extraction efficiency.

2. **Extraction Efficiency**:

- Static heating eliminates dead zones, enhancing the extraction of materials at the bottom.

- A tangential liquid inlet design dissolves floating medicinal materials quickly, significantly boosting efficiency.

3. **Slag and Liquid Discharge**:

- Features a non-tapered or mushroom-shaped bottom flange for smoother discharge.

- A central drum increases heating and discharge areas, reducing labor intensity and improving production efficiency.

4. **Operational Safety**:

- Bottom heating maintains a slightly boiling state, reducing secondary steam flow and associated risks.

- Minimizes operational hazards and ensures a safer production environment.

5. **Installation Space**:

- Requires relatively large installation space due to its design.

### Main Structural Features of Traditional Multi-Function Extractors

1. **Heating Method**:

- Relies solely on jacket heating, leading to a heating dead zone at the bottom.

2. **Extraction Efficiency**:

- Static heating and lack of bottom heat result in incomplete extraction.

- Floating herbs take longer to submerge and extract, further reducing efficiency.

3. **Residue and Liquid Discharge**:

- Conical design causes clogging and poor liquid discharge.

- Residue often forms bridges, requiring manual intervention, increasing labor intensity.

4. **Operational Safety**:

- Difficult to control secondary steam flow due to jacket heating.

- Poor steam pressure control can lead to unsafe conditions, including clogged pipelines and pressure boiling.

5. **Installation Space**:

- Compact design with a large diameter and low height, occupying less space.

Modern extractors significantly improve efficiency, safety, and operational ease compared to traditional designs.
