Emulsion breaking apparatus

Emulsion breaking an apparatus (see Figure 6) has been deve-... 

Note. (1) Batchwise extraction leads to the formation of stable emulsions which frequently take several days to break. When filling the continuous extraction apparatus, care should be taken to avoid forming an emulsion. 

The apparatus is set up as shown in Figure 5-1, p. 50, with the steam generator, trap, and sample flask on one ring stand. The glass tube used as a pressure regulator should be adjusted to within 2 cm of the bottom of the flask. A separatory funnel is used for the trap, which makes it easier to remove the condensed water. Glass wool is not used to break the emulsion, because a part of this experiment is to become familiar with different ways to break emulsions. Keep the connecting lines short to minimize the amount of condensate.

Sponge squeezed into a terracotta bowl, the concolina After decantation, the oil was collected in metal containers. This was an extremely laborious process characterized by substantial oil losses. A later improvement of the fruit peel expression process was the scodella method. The apparatus was a metallic hemisphere lined inside with small spikes, with a tube attached at its center. The fruit placed inside the hemisphere was rotated while being squeezed against the spikes thus breaking the oil cells. The oil emulsion, containing some of the wax coating the fruit, flowed into the central tube was collected, and the oil was subsequently separated by centrifugation.
