Description
You can load the very top of your column with Raschig Rings to get extra fine separation of different boiling points when distilling. Copper saddles are preferred over stainless steel or the ceramic, but you can use those below the copper saddles.
The copper reacts with impurities like hydrogen sulfide and helps with the refluxing action that removes these impurities. Copper saddles are also not porous so they last longer. Fill the top of the column with copper saddles, shaking into place as you fill. Then fill the rest of the column with stainless or ceramic packing. Still packing will increase the proof, quality and speed of your distillation. Pall Rings work great for column filling due to their large surface area. Proper use can increase the efficiency of your still and the purity of your spirits. These are factory packed by BSG BEVIE under the Still Spirits brand name.
Raschig rings are small pieces of tube used in large numbers as a randomly packed bed within distillation columns. Raschig Rings provide a large surface area within the volume of the column for interaction between liquid and vapor. Raschig rings are named after the inventor, chemist Friedrich Raschig. Each ring measures around 10mmx10mmx5mm.
In a reflux distillation column the condensed vapor from the boil goes up the column where it encounters the packing. This covers the surfaces of the rings and the finer vapors continue up the column. The top is cooler and the finest vapors pass over into the cooling section. The poorer part of the vapors drop back through the bed of Raschig Rings. As the vapor and liquid pass each other counter currently in a small space they tend towards equilibrium. Thus the less volatile material tends to go downwards, the more volatile material upwards, Increasing the proof of the product.
