Product details
Core Value:
Production Capacity Range: Annual output from 3,000 to 200,000 tons, meeting the needs of small to medium-sized and ultra-large-scale production.
Finished Product Density: Produces low-density detergent powder, with a loose pack density of 0.25 – 0.35 g/cm³, suitable for expanded hollow powder formulations.
Environmental Standards: Closed-loop circulation system design, no wastewater discharge, meeting international environmental protection requirements.
Part Two: Core Technology and Process
Working Principle:
Raw Material Preparation: Liquid raw materials (such as surfactants and additives) and solid raw materials are precisely metered, neutralized, and aged to form a homogeneous slurry.
Spray Drying: The slurry is pumped to a high-speed centrifugal atomizer at the top of the tower, atomizing it into tiny droplets.
Hot Air Contact: Filtered and heated hot air (up to 350°C) is evenly distributed from the top of the tower, making instantaneous contact with the droplets, causing rapid evaporation of moisture (evaporation rate 95-98%).
Granulation: After drying, the droplets form hollow, spherical particles, which are continuously discharged from the bottom of the tower.
Tail Gas Treatment: The tail gas containing fine powder is purified by a cyclone separator and dust removal system before being discharged; the fine powder is recycled.
Key Technological Advantages:
High-Speed Centrifugal Atomization: Ensures uniform particle size and controllable distribution.
Fully Automatic PLC Control: Pre-programmed recipes, real-time monitoring of temperature, pressure, and flow rate, enabling one-button start/stop and self-diagnosis of faults.
Energy-Saving Design: Heat recovery system, saving 20-30% energy compared to traditional drying methods.
Application
Household Laundry Detergent Production: Produces fluffy, quick-dissolving regularlaundry detergent.
Industrial Detergent Manufacturing: Produces high-concentration, functionalindustrial cleaning agent powders.Multi-Product Flexible Production Line: Combined with agglomeration moldingequipment, it can simultaneously produce low-density and high-density detergentpowders.
Existing Factory Upgrades and Retrofits: Services for increasing the capacity andoptimizing energy consumption of aging spray towers.
FAQ:
1. Is a spray drying tower suitable for producing high-density concentrated laundry detergent?
Pure spray drying towers primarily produce low-density hollow powder (0.25-0.35 g/cm³). For producing high-density concentrated powder (0.45-0.80 g/cm³), we recommend a composite process production line with an agglomerator, or a combination of tower and agglomerator.
2. What international certifications does the equipment meet?
Our equipment has passed ISO 9001 quality management system certification and CE safety certification. We can provide SGS or BV on-site factory audit reports upon customer request.
3. What is the equipment warranty period? What is the after-sales service like?
The entire machine is warranted for one year (excluding consumable parts). We provide 24-hour online technical support, overseas engineer installation guidance, and spare parts supply services.
4. Does the factory pollute the environment?
Our system design adopts closed-loop circulation and water curtain dust removal technology. The process has no wastewater discharge, and exhaust emissions meet international environmental standards.
