Used Cooking Oil Melting Plant
This melting plant is used for the recycling of (used) cooking oil or yellow grease from restaurants and the food industry into usable feedstock for e.g. the biodiesel industry.
The main purpose of a melting plant is to facilitate the logistics in collecting oil and fat from a variety of sources. The heat source can be low pressure steam, hot water, electrical coils or even hot air.
A melting plant can be designed and build for different working sizes. The model on the picture can actually be seen in action in Holland.
It comes with an oil filter installation and can be connected to an optional Bio-air filter to reduce the smell emitted to the environment. This will keep the neighbors happy. The Bio-air filter is connected through an aluminimum pipe with the roof of the melting plant, see the picture above.
The 3 main functions are:
- Thermostatically controlled heating and melting of the oil or fat which is packed in drums and IBC´s
- To offer a platform to quickly empty the drums into a basin
- Separating water and dirt from the waste oil
On the animation above you can see how it works. The oildrums are delivered by truck and put into the melting plant until it is full. By pumping in hot water the fat starts to melt and the dirt falls out into the water. The oil on top of the water will be transferred to a holding tank (not delivered). In the holding tank the oil can be heated up even higher in order to achieve that more water settles out.
The empty drums can be washed in an optionally computer controlled wash unit.
To reduce the dirt content even further the oil can be filtered in two steps. The first step is pumping the oil through a Filter Press which clarifies the hot oil and can hold up to 600 L dirt per charge. Bleaching earth can be used as an extra filtration medium, to absorb impurities like water and FFA in the oil.
By using filter bags (size #2) as the final step, the filtration size can be selected from 150 micron down to 1 micron. A PLC controls the temperature and delta pressure of the filter baghouse and switches the pumps off when the threshold is reached. In this way it both protects the pumps and the filter itself.
To measure the quality of the oil the system can be (optional) equipped with a water sensor and a particle size monitor, also used on our Biodiesel Processors.
