Model 125L, 225L, 330L, 500L and 800L -Solar Milk Tanks
The FREECOLD solar-powered milk tank is designed to preserve milk in sunny areas that are poorly connected to the electric grid. It can perfectly adapt to the climatic conditions present in Sub-Saharan Africa in particular. In this way it fully participates in the development of the production of quality local milk and to increase farmers’ incomes in the face of European competition. With a capacity of 330 liters, our solar milk tank can store about two milkings enough time to process or sell the milk. Its thermal insulation and its high cooling capacity allow it to cool the volume of a 125 L milking to a temperature of 4°C within 2 hours, with a 35°C outside temperature.
Our milk tank is powered:
- During the day using the photovoltaic solar plant
- In the night and the days without sun via batteries stocking solar energy
- A connection to the electric grid is possible if available
The FREECOLD electrical cabinet optimizes power management according to the power available at the input (PV, batteries, …), and output requirements (milk tank, battery charging). This guarantees a high quality power supply by prioritizing solar energy before using other sources.
- Rounded corners, polished welds and the stainless steel bowl guarantee hygiene and food safety.
- A 45 mm insulation layer limits heat loss from the tank.
- The stirring device of the milk makes it possible to homogenize the temperature and the fats in the whole tank, while nevertheless avoiding foaming.
- The photovoltaic modules simultaneously power the cooling unit and recharges the batteries, thus guaranteeing the autonomy of the installation.
- Batteries make it possible to smooth the intermittences of the solar source and to supply the system at night and on days without sun.
- Openwork side panels allow the heat of the refrigeration unit to escape while preventing the intrusion of small animals and rodents inside the system.
- Complete emptying of the tank is possible using a stainless steel outlet valve.
