 Low-Temperature Steam Blanching Equipment

Food Safety with Optimal Quality 

Times are changing and blancher validation to achieve a 5-log reduction of Listeria is now a key to a process under control, without affecting the organoleptic characteristics of the end product.  The CoolSteam technology offers the perfect balance of efficiency, flexibility, consistency, and power.

Laitram’s revolutionary patented CoolSteam® cooking technology delivers higher quality and food safety with lower energy and water costs than competing technologies.

Yield Savings

Precise low temp and forced convection method are used to allow for optimal recipe creation without overcooking the product and losing yield via weight or crumbs.

Why CoolSteam?

We've applied 20 years of cooking science experience to rethink blanching.

The CoolSteam Blancher offers the same precise uniformity, simplicity, and control.

Precise Temperature Control within chamber, below 100°C with a homogenized mixture of air and steam.

The lower-temp environment (55 ˚ -100˚C) prevents yield loss and flavor on outside surface.

The product core reaches the lethal temperature range without overcooking the outside surface.

CoolSteam produces a uniform and consistent blanch thanks to forced convection, the chamber design, and the homogenized mixture of air and steam in the chamber, even with bed depths of 17+cm. Tested side by side against other blanchers, no cold spots, no peroxidase positives, the lethality of 5+logs.
