AlfaVap Inline
Efficiently concentrate heat-sensitive, low- to medium-viscosity and low- to medium-fouling products with the multi-effect Alfa Laval AlfaVap Inline. Purpose-built on a modular process skid, this ultra-compact, energy-efficient rising film plate evaporator reduces capital expenditures, operating expenses and carbon footprint while raising product quality and accelerating time to market.
Evaporation optimized for the food industry
- Ultra-compact evaporator, like no other
- Lower retention time, higher product quality
- Easy to operate
- Easy to access, minimal maintenance
- Global company with 140 years of food processing expertise and extensive local service network
Sustainably concentrate food products with the Alfa Laval AlfaVap Inline climbing film plate evaporator. It takes up less floor space, is lower in height and more lightweight than comparable evaporators. Manufactured using less steel, it requires less fuel to transport and a smaller concrete foundation for support. It fits into tight spaces or existing structures, reducing installation costs.
The AlfaVap Inline reduces retention time to minutes. It minimizes product exposure to heat by up to five times compared to falling film evaporators, resulting in higher product quality.
Typical applications include fruit juices, sugar and sweeteners, herbal extracts, and protein hydrolysates.

How does this Alfavap inline plate evaporator work
The AlfaVap Inline is a high-performance plate evaporator designed for enhanced concentration. It features a modular design. It comprises a complete module with one or more evaporator plate packs connected to a vapor-liquid separation vessel. Each evaporator consists of a plate pack. The liquid feed enters the evaporator through two inlets at the unit’s bottom. As the liquid flows over the plates in one channel, the steam in the other channel heats the plates, causing the liquid to evaporate. The heated vapour rises through the channels. The vapour-liquid mixture leaves the plate heat exchangers and enters a vapour separator, an integral part of the AlfaVap Inline module. The mixture separates into a vapour, which exits through an outlet at the top, and a liquid, which flows through an outlet at the bottom of the separator for subsequent processing is directed to the next process or final extraction point.
This rising film evaporator operates with small temperature differences, allowing for an increased number of effects without increasing the overall temperature difference. This enhances energy efficiency by reducing steam consumption and operating costs.
Fossil free concentration process
A lot of water is transported on our roads today, and by reducing the water content in food products using an evaporation system, you will reduce the energy consumption in transportation.
The concentration step is often the highest energy consumer in your processing plant. With the AlfaVap Inline, you can reduce the energy required for your concentration process by shifting from fossil fuels to electrical energy. This makes it possible to achieve a fossil free energy solution for concentration, significantly reducing carbon emissions and lowering operational costs.
