ALTUM – Vacuum Olive Malaxer for High-Antioxidant Oil

ALTUM applies patented vacuum technology to simulate thermal effects without heat—boosting polyphenols, oleocanthal, and yield while preserving antioxidant properties.

Application:

The BSTM ALTUM Vacuum Malaxation Unit enhances the breakdown of olive cells and enzymatic activity through high vacuum technology applied via our patented automatic systems. As a result, increases of up to:

- 10% in oil yield,
- 30% in polyphenol content,
- 60% in oleocanthal levels
have been achieved.

Thanks to its double-jacketed design, the temperature of the olive paste can be kept at the desired level throughout the process.

Advantages:

- The double-jacketed design allows the paste to maintain the target temperature.
- Easy-to-clean structure.
- Significant gains in oil ratio and phenolic content through easily applicable high vacuum technology.
- The horizontal design with no dead zones ensures all olive cells come into contact with vacuum.

Design:

In the BSTM ALTUM Malaxation Unit, a horizontal body is preferred to ensure that all olive cells are exposed to vacuum. Since vertical malaxers only allow vacuum to function effectively in the upper layers, this design was deliberately avoided.
The horizontal body with no dead zones ensures full and consistent vacuum contact with all olive material.

This structure also simplifies cleaning operations. Each malaxer unit is equipped with one motor responsible for mixing the olive paste. BSTM ALTUM Malaxation Units are designed to operate under high vacuum and are covered by a patent registered in our company’s name.
All surfaces in contact with olive paste are made of stainless steel.

Working Principle:

Under high vacuum and with special blade design, high oil and polyphenol yield is achieved.
Thanks to the automation system, the high vacuum technology can be operated automatically.
It simulates the effect of 60°C on olive cells at only 22°C, by creating a pressure difference between the inside and outside of the cells. This ruptures more cell membranes and increases both yield and polyphenol transfer into the oil.

Volatile compounds begin evaporating at 22°C and are fully lost by 35°C.
BSTM ALTUM Malaxers optimize this process, simplify complexity, and provide a user-friendly solution.
