Chemical Prepration Vessel

The Dhara Chemical Preparation Vessel operates on a three-stage process concept, with each vessel optimized for a specific function and synchronized through a centralized PLC-based control system. This architecture ensures controlled material flow, precise parameter regulation, and full process traceability.

Stage 1 — Pre-Mixing & Dispersion Vessel

Controlled Slurry Formation and Thermal Conditioning

This vessel ensures accurate dispersion of sizing chemicals and controlled pre-heating prior to cooking.

Design & Process Features

• Vertical cylindrical vessel with dished ends for optimized internal flow
• High-efficiency, top-mounted anchor agitator with VFD control
• Steam-jacketed or electric pre-heating system
• Load-cell-based weight measurement for precise ingredient dosing
• Prevents agglomeration and ensures uniform pre-cook viscosity

Stage 2 — Pressure Cooking Vessel

Controlled Gelatinization Under Defined Pressure Conditions

The pressure cooking vessel performs complete gelatinization of sizing components under precisely controlled pressure and temperature.

Design & Process Features

• Pressure-rated SS 304 / SS 316L construction for continuous operation
• Bottom-entry propeller agitator for uniform heat distribution
• High-efficiency steam jacket or direct steam injection
• Optional vacuum degassing to remove entrapped air
• Integrated CIP system for hygienic cleaning

Stage 3 — Storage & Feeding Vessel

Homogenized Holding and Consistent Supply

This vessel maintains cooked size under controlled temperature and agitation until application.

Design & Process Features

• Stainless steel with mirror-polished interior
• Conical bottom design for complete drainage
• Low-shear agitation to prevent sedimentation
• Jacketed temperature maintenance with sensor-controlled steam valves
• Multiple outlet connections with flow control

The entire system is governed by a centralized PLC + SCADA architecture, ensuring precise control, safety, and traceability.

• Integrated PLC with real-time feedback loops
• HMI touchscreen interface for recipe management and process visualization
• Batch memory and data logging for audit and quality compliance
• IoT-ready remote diagnostics for proactive maintenance
• Safety interlocks and alarms for pressure, temperature, and overfill protection

• Repeatable Batch Quality
  Controlled gelatinization and precise viscosity development ensure consistent sizing results.
• Energy Optimization
  Intelligent pre-heating logic and regulated steam usage reduce energy consumption.
• Minimal Operator Dependency
  Fully automated sequencing with alerts minimizes manual intervention.
• Modular Scalability
  Configurable from single-vessel installations to large-scale chemical kitchens.
• Clean & Safe Operation
  Hygienic, pressure-certified, CIP-enabled vessels ensure contamination-free processing.
