SolarDairyTech
Innovative Technology for Concentrating Milk and Other Liquid Foods Without Thermal Evaporation
The food industry is rapidly evolving towards more efficient, sustainable, and cost-effective processes. Traditionally, liquid concentration, especially in dairy production, has been an energy-intensive process due to thermal evaporation. SolarDairyTech revolutionizes this paradigm by employing indirect solar energy to concentrate milk, juices, and other liquids without relying on heat-based evaporation.
This automated and scalable system presents an innovation opportunity for dairy and food sector companies aiming to reduce operational costs, minimize environmental impact, and enhance product quality.
What is SolarDairyTech?
SolarDairyTech is a patented process for concentrating milk and other liquids that utilizes physical principles of molecular interaction to extract water without the need for heat. This innovative method preserves the nutritional and sensory properties of the product while significantly reducing energy consumption.
Designed for medium- and large-scale producers, this technology can be seamlessly integrated into milk processing plants, juice factories, and other food facilities, adapting to various production needs.
The SolarDairyTech machine features an upper and a lower container, both made of reinforced glass, allowing water transfer without thermal evaporation. Its high-capacity hydraulic system automates the tilting of the upper container for efficient product discharge. Additionally, it incorporates a wiper-like mechanism that optimizes water extraction and a screw conveyor that facilitates the transfer of the concentrated liquid to the next processing stage.

Modular Design Tailored for Industrial Production
SolarDairyTech is specifically designed for medium- and large-scale dairy producers. Its modular design allows multiple units to operate in parallel, offering flexible scalability with capacities ranging from small batches up to 200,000 liters per cycle or more, depending on production needs. Moreover, the system is highly adaptable, enabling its application in the concentration of juices, extracts, and other liquid foods, extending its use beyond dairy processing.
Concentration of Dairy and Liquid Foods Without Thermal Evaporation
The system operates through a concentration method without thermal evaporation, based on the interaction between different water densities within the milk or processed liquid.
Process Stages
- System Preparation:
- The lower container is filled with water, matching the volume of the liquid to be processed.
- The upper container is loaded with up to 5,000 liters of milk, juice, or any other liquid food.
- Water Extraction:
- In the upper container, the liquid contains high-density water (HDW) near the surface and low-density water (LDW) at the bottom.
- In the lower container, the water is also separated into HDW and LDW.
- The natural attraction between HDW and LDW molecules in both containers allows water molecules from the liquid to pass into the lower container through the bottom of the upper container, functioning as a molecular-level filter.
3. Process Optimization:
- A wiper-like system continuously removes water droplets accumulated at the base of the upper container, improving process efficiency.
- Within a few hours, the liquid volume is reduced by up to 50%, without the need for heat or chemicals.
4. Automated Discharge:
- Once the desired concentration level is reached, the hydraulic system tilts the upper container, and the concentrated milk or juice is discharged through a screw conveyor, directing it to the next production phase.
