Cotton Bleaching Machinery

Keir Attributes (Boiling Vessel Description)

Keir is a large, pressurized or open vessel used for boiling, bleaching, and scouring cotton, including surgical cotton absorbent cotton. It is an essential part of the cotton purification process, ensuring the removal of natural oils, waxes, and impurities to make the cotton highly absorbent and suitable for medical applications.

Working Principle Attributes

• Loading: Raw cotton is placed inside the kier.

• Boiling & Bleaching: Steam or heated chemicals like caustic soda, hydrogen peroxide are circulated.

• Impurity Removal: Natural waxes, pectins, and non-cellulosic materials are dissolved.

• Draining & Washing: The processed cotton is thoroughly rinsed.

• Cooling & Unloading: The treated cotton is taken out for further drying and hydro extraction.

Key Features Attributes

• Uniform Processing: Even chemical penetration ensures high absorbency.

• Customizable Heating System: Steam, electric, or direct heating options.

• Durable Construction: Mild Steel.

• Control System: Manual Control, Automatic/Semi-Automatic options available.

Applications

• Surgical cotton manufacturing.

• Medical and pharmaceutical cotton processing.

• Textile and hygiene product manufacturing.

Hydro Extractor Attributes (Description of Use)

Hydro extractor is a high-speed centrifuge designed to remove excess water from freshly washed or bleached cotton through centrifugal force. It is a crucial machine in surgical cotton processing, ensuring that the cotton is efficiently dried before further processing.

Working Principle Attributes

• High-Speed Spin: The hydro extractor spins at high speeds, generating centrifugal force.

• Water Expulsion: Water is expelled from the cotton through perforations in the drum.

• Drainage: The extracted water is drained out through an outlet.

• Process Efficiency: The process significantly reduces drying time before cotton is sent for further processing.

Key Features Attributes

• High-Speed Centrifugal Operation: Removes excess water effectively.

• Stainless Steel Drum: Prevents contamination and ensures hygiene.

• Shock Absorbing System: Reduces vibration and noise.

• Automatic Braking System: Ensures safety during operation.

• Balanced Loading: Prevents machine imbalance and ensures uniform extraction.

• Efficient Water Drainage: Fast removal of water to speed up drying.

• Fully Enclosed Design: Ensures operator safety and hygiene.

• Automatic Timer: Enables precise control over the extraction cycle.

• Heavy-Duty Construction: Ensures durability and long operational life.

• Low Maintenance: Designed for easy operation and servicing.

Applications

• Surgical cotton manufacturing.

• Medical and pharmaceutical cotton processing.

• Textile and hygiene product manufacturing.

Boiler Attributes (Description of Use)

Boiler is used to generate steam, which is essential for heating the kier (boiling vessel) and other processing equipment in the cotton bleaching process. The steam helps in the removal of natural impurities, ensuring that the cotton is properly purified and made absorbent for medical use.

Working Principle Attributes

• Fuel Feeding: Fuel biomass, gas, or diesel is fed into the combustion chamber.

• Water Heating: The boiler heats water to generate steam.

• Steam Circulation: The steam is supplied to the kier and other equipment in the bleaching plant.

• Temperature Control: The system maintains the desired temperature for effective bleaching.

• Exhaust & Safety: Excess steam is released through safety valves and a chimney.

Key Features Attributes

• High Efficiency: Ensures optimal steam generation for bleaching.

• Fuel Flexibility: Can run on gas, diesel, wood, or biomass.

• Automated Operation: Reduces manual intervention.

• Safety Mechanisms: Equipped with emergency shutdown and pressure control.

Applications

• Generates high-pressure steam for essential textile processes: bleaching, dyeing, printing, and finishing.

• Essential steam source for all wet processing stages in the cotton and textile industry.
