Industrial vacuum concentrators are highly cost-effective and environmentally efficient
In recent years, products whose composition include natural organic additives, have experienced significant growth. Some examples of this type of products can be found in sectors such as cosmetics and natural medicine (aloe vera in the picture), as well as in prepared foods (nutraceuticals), sweeteners like stevia or biological insecticides.
In order to elaborate these products, it is necessary to obtain the natural additive extract concentrate required in each case. These are usually natural botanical extracts from plants, flowers, fruits, fungi, roots, etc.
For such purpose, it is required to carry out a process of separation and concentration of substances in liquid and solid mixtures, so as to obtain the additive concentrate that can later be incorporated into the production process.
A industrial vacuum concentrator is the most effective method nowadays to ensure a high quality fruit concentrate.
This innovative procedure allows single-stage simultaneous separation and concentration processes:
- The solvent or extractant is evaporated
- The active principle is concentrated to dryness
The whole process of separation and concentration takes place at low temperatures of between 25°C and 30ºC, and therefore the additive active ingredients are not altered nor denatured.
In addition, vacuum concentrators are highly cost-effective and environmentally efficient, since they enable the recovery of solvents used in the process for later reuse and emit no fumes and emissions into the environment, consuming a moderate amount of electricity (between 150 and 250 w/evaporated liter). They also can work autonomously 24 hours/day, requiring virtually no maintenance, with a life span of over 20 years.
