Detailed Product Description
The Semi-Automatic Plate Evaporator Crystallizer operates on the principle of thin-film evaporation combined with controlled crystallization. Process fluid is pumped through a series of corrugated plates where heating medium (steam or hot water) flows on the opposite side. The high turbulence and large surface area promote rapid evaporation. As the solution concentrates, it enters the crystallization chamber where cooling or further evaporation induces supersaturation and crystal growth. The touch screen controller monitors key variables and automatically adjusts feed flow, heating temperature, and vacuum level to maintain stable conditions.
Why choose a plate-type design over traditional shell-and-tube? Plate heat exchangers offer several advantages: they require less space (up to 80% smaller footprint), are easier to inspect and clean (plates can be disassembled), and achieve higher heat transfer coefficients. Additionally, the short residence time minimizes product degradation, making it ideal for heat-sensitive substances. For crystallization applications, the plate design allows gentle agitation and uniform temperature distribution, resulting in more consistent crystal morphology and size distribution.
Semi-automatic control strikes a balance between full automation and manual flexibility. Operators can set target parameters (temperature, pressure, evaporation rate) and let the PLC maintain them, or intervene manually for special batches. The touch screen provides clear data visualization, alarm logs, and trend graphs, enabling operators to make informed decisions. This reduces reliance on highly skilled labor while still allowing customization.
Versatile applications include: concentration of fruit juices, dairy products, and pharmaceuticals; recovery of solvents or salts from industrial wastewater; production of crystalline chemicals (e.g., sodium sulfate, ammonium chloride); and treatment of brines in the chlor-alkali industry. The 316L material makes it suitable for corrosive environments containing chlorides, sulfides, or organic acids.
Customization options are available: different plate materials (e.g., Hastelloy, titanium), various gasket materials (EPDM, Viton, PTFE), explosion-proof electrical components, additional cooling stages, CIP (clean-in-place) systems, and remote monitoring via Ethernet. Our engineering team can design a unit tailored to your specific process conditions and throughput requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum concentration I can achieve with this evaporator crystallizer?
A: The final concentration depends on the solubility of your solute. Typically, you can reach up to 60% solids or more, but for highly soluble salts, concentration can go higher. We recommend providing your feed composition for a precise recommendation. -
Q: Can the machine handle viscous or fouling fluids?
A: Yes, the plate design creates high shear and turbulence, reducing fouling. For extremely viscous fluids, we may recommend an agitated crystallizer or larger plate spacing. Customization options are available. -
Q: Is the touch screen interface available in multiple languages?
A: Yes, the HMI supports English, Chinese, and other languages upon request. The PLC can be programmed to display your preferred language. -
Q: How long does it take to install and commission the machine?
A: Our skid-mounted unit can be installed in 2–3 days with basic utilities (power, cooling water, steam). Commissioning with our engineer typically takes 3–5 days, including training for your operators. -
Q: What is the electricity consumption per hour?
A: The main power consumption comes from the feed pump and control system. Under full load, it consumes about 3–5 kW (excluding heating source). The actual value depends on operating conditions. -
Q: Do you provide spare parts and after-sales support?
A: Absolutely. We maintain a stock of common spare parts (gaskets, plates, sensors) and can ship them within 48 hours. Our technical team is available 24/7 for remote assistance, and we offer on-site maintenance contracts. -
Q: Can I use this machine for solvent recovery where the solvent is flammable?
A: Yes, but we must equip explosion-proof electrical components and inert gas blanketing. Please inform us of the solvent properties so we can design a safe system. -
Q: What is the typical delivery time?
A: Standard units are delivered within 30–45 days after order confirmation. Customized units may require 60–90 days depending on complexity.
