8-10KW Evaporator for A Vegetable Pickling Plant

An 8-10kW evaporator for a vegetable pickling plant is typically a compact, low-temperature vacuum evaporator designed for wastewater reduction or brine concentration. Using a heat pump or electric elements, this capacity handles an evaporation rate of roughly 10 to 25 liters per hour, lowering your disposal costs by concentrating waste volumes by up to 98%

Key Considerations for Pickling Plants

Because pickling involves high concentrations of salt, vinegar, and organic acids, the equipment must be properly specified:

Corrosion Resistance: Standard stainless steel (SS304) can degrade in high-chloride pickling brines. You will need SS316L, Duplex, or even Titanium heat exchangers.

Energy Efficiency: Heat Pump Vacuum Evaporators run entirely on electricity and operate at low pressures (35° C-60° C), which saves energy and prevents the degradation of any organic byproducts in the wastewater.

Fouling and Scaling: Pickling water contains suspended solids and high salt loads. Scraped-surface evaporators are generally the best choice to prevent salt crystallization on the heating surfaces.

Zero Liquid Discharge (ZLD): These systems allow you to recover up to 98% of the water for facility cleaning or washdown, leaving a heavily concentrated slurry to dispose of.

To help you size and source the ideal unit, could you clarify your exact requirements:

What is the volume of wastewater you need to process per day?

What is the typical composition of your wastewater (e.g., salt levels, acetic acid, suspended solids)?

Is your primary goal effluent reduction/disposal, or brine concentration and salt recovery?
