### Features and Structure of Diatomaceous Earth Filters
1. **Structure**:
- The filter consists of a housing, intermediate shaft, filter plate, filter screen, guide rod, air valve, glass mirror, impeller, and other components.
- All liquid-contacting parts are made of stainless steel.
- The housing is available in multiple or single sections, with rubber seals between sections for easy disassembly and cleaning.
2. **Advantages**:
- Energy savings of 92%.
- Reduction in wine loss by 90%.
- Equipment costs reduced by 2/3.
- Production labor requirements reduced by 3/4.
- Retains odor, is non-toxic, free of suspended solids and sediment, and provides clear, transparent, and highly efficient filtration.
- Occupies a small footprint, is lightweight and flexible, and easy to move.
3. **Applications**:
- Widely used in industries such as white wine, fruit wine, low-alcohol wine, white wine, medicinal wine, grape wine, and water treatment.
- Achieves a filtration clarity of 99.8% and can remove E. coli.
- Removes particles (including microorganisms) smaller than 1 to 0.1 microns.
### Diatomaceous Earth Filter Installation and Instructions
1. **Installation**:
- Refer to the installation diagram for proper setup.
- Use rubber hoses to connect all components.
- Open regulating valve 9, inlet valve 7, and outlet valve 6.
- Start beverage pump 8 to pump the turbid liquid from container 10 into the filter.
2. **Pre-Coating Process**:
- Place approximately 150-200 kg of unfiltered liquid in container 10, add diatomaceous earth, and stir evenly.
- The diatomaceous earth ratio is provided in the table (clear liquid is recommended for optimal results).
- The turbid liquid is pre-coated and pumped into the filter, where the diatomaceous earth flows onto the filter cloth and circulates back into container 10 through outlet valve 6.
- After repeated circulation, the diatomaceous earth is evenly attached to the filter cloth, resulting in clear and transparent filtered liquid.
3. **Operation**:
- Once the required level is reached, close outlet valve 6 and open outlet valve 5 to bottle the filtered clear liquid.
- Operate the machine with a dedicated person.
- Never close outlet valves 5 and 6 while operating to avoid excessive pressure and damage to the machine components.
4. **Maintenance**:
- Before starting the machine, open exhaust valves 1 and 4.
- After shutting down, close outlet valves 5 and 6, inlet valve 7, open exhaust valves 1 and 4, and drain the liquid from the filter cartridge through the drain valve.
- Clean the diatomaceous earth and any debris from the filter cloth with clean water, then reassemble the filter element in the correct order before operation.
5. **Filtration Rate and Volume**:
- Depend on factors such as the nature of the beverage, alcohol content, sugar content, concentration, impurity content, filter aid ratio, dosage, and pressure requirements.
- Additional diatomaceous earth can be added during production to increase continuous filtration time and filtration rate.
6. **Using Diatomaceous Earth Additives**:
- Ensure a uniform, stable, and crack-free diatomaceous earth pre-coating.
- The thickness of the pre-coating should be around 2 mm, free of cracks and flaking.
- Adjust the pressure to an appropriate range of 0.5-1.5 kg/cm² before filtration.
- Maintain pressure within the filter to prevent the diatomaceous earth layer from falling off during operation.
- Restart the filter according to the first-time operation process to avoid affecting normal production.
By following these instructions and maintaining the proper conditions, the diatomaceous earth filter can provide efficient and high-quality filtration for various beverages and liquids.
