The theory of the distillation is quite simple. We heat the substrate forcing it to evaporate and then we condense the vapor. It is mainly used for the alcohol and essential oil production.
In different applications, people's preference is not same. Usually a still used for alcohol is made of copper for it removes sulfur-baased compounds from the alcohol that would make it unpleasant to drink. It has a name we are familiar with, that is, moonshine still. There are many kinds such as pot still, alembic still, reflux still and column still. Despite the name, moonshine still is also can be used to distill water and essential oil. Modern stills are made of stainless steel with copper innards. Using this combination of metals is much cheaper because it prevents erosion of the entire system and lowers copper levels in the waste product.
A distiller used for essential oil is usually made of stainless steel and glass. The glass essential oil distiller kit is specifically designed for easy steam extraction of essential oil from plant materials at home. Therefore, its capacity is usually very small from 2L to 10L. For commercial use, obviously stainless steel essential oil distiller is more suitable.There are some advantages of using stainless steel than other materials:
Long service life. It can efficiently avoid the erosion from different plant materials and distillation process.
Safe and Clean. With stable physical and chemical properties, it has little possibility to do harm to the work and it is very easy to clean. As we all know, flower farm owner usually need to extract oil from different aromatic plants.
Continuously expandable capacity. The capacity of stainless steel essential oil machine is from 50L to 5000L or even larger.
Therefore, if you want to start your essential oil business, our suggestion is to choose stainless steel essential oil distiller.
