VVU vacuum evaporators for condensed milk, dulce de leche, jams, fruit butters, preserves and sauces
The VVU vacuum evaporator heats the product under vacuum and evaporates moisture from it at a reduced temperature, so the product does not burn and keeps its flavour and colour. Milberg VVU units are used to cook condensed milk and dulce de leche (boiled condensed milk), jams, fruit butter, preserves and sauces, as well as pastes, cosmetics and pharmaceuticals. Units of 500 L are ordered most often; we also make smaller and larger ones to suit the task. Price from €8,900.

Details How to choose a vacuum evaporator
- Vacuum depth. The deeper the vacuum, the lower the boiling point and the better the flavour and colour of the product. The most common mistake is choosing a cheaper unit: cheap versions have thinner metal and a weaker vacuum.
- Vacuum pump. Cheap units are fitted with an ordinary air compressor, which is not suitable for deep vacuum and wears out quickly. Milberg fits liquid-ring vacuum pumps.
- Volume. Selected for the batch size and production plan. Our customers most often choose 500 L; we also make 60 L, 150 L and larger units.
- Version for your product. A typical VVU has a heating jacket with electric heating elements, cooling, a frame agitator with scrapers, 50 mm thermal insulation and a cleaning head. Steel is AISI 304, 316 or 321; the agitator and pump are selected for the product.
- Control. A control panel with a temperature controller using two sensors — jacket and product — or full recipe-based automation.
