Used ANHYDRO Falling Film Vacuum Evaporator – 6,500 kg/h | MVR x2 | 5 Calendria | CIP

Manufacturer Information:

• Original Manufacturer: ANHYDRO

• Rebuilt By: BONTECH A/S (Denmark)

• Type: Falling Film Vacuum Evaporator

• Condition: Used & Rebuilt – Excellent working condition

• Current Use: Stick water evaporation from the fish industry

• Original Design: TVR (Thermal Vapour Recompression) for dairy applications

Description:

This Used & Rebuilt ANHYDRO Falling Film Vacuum Evaporator is a fully operational, mechanical vapour recompression (MVR) evaporator system originally built for milk concentration in a Norwegian dairy. It was later relocated and redesigned by BONTECH A/S for processing fish industry stick water, with a water evaporation capacity of 6,500 kg/hour.

Now equipped with two MVR units connected in series, the system is optimized for energy-efficient evaporation. The plant consists of five calendria, housing a total of 310 pipes (Ø51 mm, each 7 meters long). It also includes a Clean-In-Place (CIP) system and is currently still installed at its operating location.

While the Westfalia separator is not included, this plant is ready for reinstallation and requires only minor pump reconditioning before full operation.

• Robust ANHYDRO construction, enhanced by BONTECH retrofit

• Designed for energy-efficient continuous evaporation

• Compact, modular setup ideal for dairy, marine, and wastewater applications

• Ready to be relocated and recommissioned

• Ideal for stick water, fish waste, or other high-moisture byproducts

Applications:

• Fish stick water evaporation

• Marine by-product and fish meal processing

• Dairy (milk and whey) concentration

• Food waste and protein concentrate processing

• Liquid waste reduction in food and beverage industries

• Concentration of high-moisture industrial or agricultural effluents

• Nutraceutical or pet food ingredient production

What might this be used for?

• Reducing waste volume in fish meal or fish oil production

• Recommissioning for milk, whey, or lactose concentration

• Creating concentrated protein liquids from marine waste

• Improving energy efficiency over traditional TVR or steam-heated evaporators

• Expanding or upgrading existing liquid concentration capacity

• Integrating into a rendering or food recovery system

• Deploying in a coastal or aquaculture processing facility

• Adapting for use in nutrient recovery from food processing waste streams

• Replacing aging evaporators with a refurbished, proven system

• Saving operational costs through MVR energy recapture technology
