High-temperature alcohol-resistant active dry yeast and its application technology

### High-Temperature Alcohol Active Dry Yeast (AADY)

**Characteristics**:

1. **Enhanced Fermentation Performance**:

- Effective at both room temperature (30°C) and high temperature (42°C).

- Increases fermentation temperature by over 6°C compared to conventional strains.

- Reduces cooling water and electricity consumption, saving 10,000 tons of water and 9,000 kWh of electricity per ton of yeast.

2. **Ethanol Tolerance**:

- Tolerates ethanol concentrations up to 13% (V/V).

- Suitable for concentrated fermentation, increasing equipment utilization by 20%.

3. **Quality Standards**:

- Moisture content: <5%.

- Viable bacterial rate: ≥80%.

- Bacterial count: >40 billion/gram.

- Long shelf life, pure, and easy to use.

4. **Economic Benefits**:

- Controls acidity and increases yield in alcohol and liquor production.

- Requires no additional fixed asset investment; replaces traditional yeast culture processes.

**Applications**:

- Used in alcohol and liquor production to improve efficiency, reduce costs, and ensure safe summer production.

**Usage**:

- Directly added to fermentation tanks, simplifying the distillery process.
