Weber Vacuum Group is a global leader in vacuum cooling and freeze drying solutions, serving clients across the food, bakery, floriculture, and pharmaceutical industries. With Dutch engineering excellence and over a decade of specialized expertise, Weber delivers cutting-edge technology that maximizes shelf life, optimizes product quality, and reduces energy costs.
In the baking industry, vacuum cooling is a game-changing technology that drastically cuts down baking and cooling time while improving bread structure, crust crispness, and overall yield. This is especially impactful for gluten-free production, where shape, texture, and volume can be difficult to control using traditional methods.
For fresh produce like vegetables and herbs, Weber’s vacuum pre-cooling solutions prevent spoilage and extend shelf life by rapidly reducing field heat, minimizing respiration, and maintaining peak freshness from field to shelf.
In cooked food applications, such as airline meals or sushi rice, vacuum cooling enables ultra-fast, uniform cooling—slashing bacterial risk and ensuring precise temperature control for both safety and taste.
Weber’s vacuum freeze drying solutions, marketed under the WeDry brand, are ideal for preserving sensitive ingredients, such as fruits, herbs, pet food, and pharmaceutical compounds. This innovative method retains color, flavor, and nutrients—at minimal energy cost.
With global support, rentals, and financing options, Weber Vacuum Group offers scalable solutions for operations of all sizes.
