Double stages evaporator

High-Efficiency Evaporators - Precision Concentration Systems

Product Overview

Broyue’s falling film evaporators are engineered for gentle, high-efficiency concentration of heat-sensitive products in pharmaceutical, dairy, and food processing industries. Our systems combine GMP-compliant design with automated PLC control for consistent, scalable production.

Key Features & Benefits

Advanced Evaporation Technology

- Falling Film Design:

- Uniform liquid distribution for no localized overheating

- 30% higher efficiency vs. rising film evaporators

- Optional Scraped Surface: For viscous products (e.g., honey, syrups)

GMP-Compliant Design

- CIP/SIP-ready: Rotating spray balls, self-draining surfaces

- Real-time monitoring: - Brix density (inline refractometers)

- Vacuum pressure (PID-controlled)

- Visible process: Large sight glasses with LED illumination

Energy-Saving Configurations

System Type	Steam Consumption (kg/kg water)	Typical Applications
Single-effect	1.1–1.3	Small-batch, solvent recovery
Double-effect	0.55–0.65	Dairy, juice concentration
Triple-effect	0.35–0.40	Large-scale pharma/chemical
MVR	0.05–0.10 (compressor-driven)	Ultra-low energy operations

System Components

✔ Heat Exchangers:

- PHE (Plate): For high thermal efficiency

- Shell & Tube: For fouling resistance

✔ Separation & Recovery:

- Cyclonic separators (minimize product loss)

- Solvent condensers (chilled water/glycol)

✔ Automation:

- PLC/HMI with recipe storage

- Auto-concentration via density feedback
