Stainless Steel Single Effect Evaporator is a fundamental and highly efficient industrial system designed to concentrate solutions by evaporating the solvent, typically water, through the application of heat. It operates as a single unit, utilizing fresh steam (or another heating medium) in a heat exchanger to boil the product under a controlled vacuum.

Vacuum Evaporation Technology: Operating the entire system under a vacuum significantly lowers the boiling point of the solvent. This allows for gentle processing of heat-sensitive materials, preventing thermal degradation and preserving valuable product attributes like flavor, aroma, and nutritional value.
High-Efficiency Heat Exchangers: Utilizes precision-engineered calendria-type or plate heat exchangers designed to maximize heat transfer surface area. This ensures optimal energy transfer from the steam to the product, improving thermal efficiency.
Advanced Separation Technology: Incorporates a dedicated Separator or Vapor Liquid Separator designed for high efficiency. This ensures that entrained liquid droplets are effectively removed from the vapor stream, maximizing product yield and preventing product loss.
Programmable Logic Controller (PLC) Automation (Optional Configuration): Features an integrated touch-screen PLC control system for precise automation and monitoring. It regulates critical parameters such as temperature, vacuum level, feed flow, and product density, ensuring consistent results and repeatable batch quality.
In-Tank Condenser (Optional): Some models feature an integrated condenser, creating a more compact footprint and simplifying the overall system architecture.
Robust Construction: Built entirely from food-grade or pharmaceutical-grade stainless steel (SS304 or SS316L), offering excellent durability and resistance to corrosion and erosion.
Hygienic & Sanitary Design: Features a high-quality internal mechanical polish (typically Ra ≤ 0.8µm or better), CIP (Clean-in-Place) spray balls, and sanitary fittings to meet hygiene requirements for food and pharmaceutical applications.
Operational Simplicity: The single-stage design makes it easy to operate, maintain, and clean, requiring less operator training compared to more complex multi-effect systems.
Compact Footprint: Its relatively simple configuration requires less floor space, making it suitable for smaller production facilities or pilot plants.
Gentle Processing: Low-temperature evaporation under vacuum protects heat-sensitive products from damage.
High Flexibility: Ideal for batch or continuous processing of multiple different products on the same line with minimal changeover time.
Food & Beverage: Concentrating fruit juices, milk, tea extracts, sugar syrups, and natural flavors.
Pharmaceutical & Biotechnology: Concentrating herbal extracts, purification of intermediates, and recovering solvents from process streams.
Chemical Industry: Concentrating acids, alkalis, inorganic salts, and organic compounds on a smaller scale.
Dairy Industry: Pre-concentration of milk and whey.
Pilot Plants & R&D: Perfect for process development, scale-up trials, and low-volume production due to its flexibility and lower initial investment.
Wastewater Treatment: Reducing the volume of industrial effluent for more cost-effective disposal or further processing.
Lower Capital Investment (CAPEX): The single-effect design has a significantly lower initial purchase cost compared to multi-effect or MVR evaporators, making it an accessible entry point.
Proven Reliability & Ease of Maintenance: With fewer components and a straightforward design, it offers high operational reliability, ease of troubleshooting, and lower maintenance costs.
Perfect for Smaller Batches & Multiple Products: Its flexibility makes it the ideal choice for facilities that produce a variety of products in smaller quantities, requiring frequent changeovers.
Quick Installation & Commissioning: The simpler system design allows for faster installation and startup, getting your production online sooner.
Excellent Value for Specific Needs: For operations where steam costs are low or evaporation capacity requirements are modest, it represents the most economically sensible solution.
Constructed entirely from high-quality stainless steel (grades 304 or 316L), it offers superior corrosion resistance, ensures product purity, and meets stringent hygienic standards. This type of evaporator is prized for its simplicity, reliability, and cost-effectiveness for lower-capacity applications or processes where flexibility and ease of operation are paramount. It is an ideal workhorse for a wide range of industries, from food processing to chemical manufacturing.
