Preparing for winter will remove most of the remaining butane and remove undesirable elements such as fats, lipids and waxes. The ultimate goal is to improve the quality and flavor of the extract by separating undesirable lipids from desirable components, such as cannabinoids and terpenes. The basic premise of winter preparation is that a cold solvent is used to solubilize the waxes that are then removed from the solution. So, to clarify it, was your butane extract dewaxed beforehand? If not, is that why you are preparing for winter? It's probably not the safest thing to do for winter with residual butane than using ethanol.
Dewaxing, similar to preparing for winter, removes unnecessary fats and waxes from the final product. Dewaxing dissolves the crude extract in butane, usually at sub-zero temperatures. In most cases, this can occur within a closed loop system through an in-line dewaxing element. Subzero temperatures make waxes and lipids insoluble in the solvent, allowing crude oil to filter through micrometric filters.
Winter preparation is a similar essential process used to remove undesirable compounds such as waxes, fats, lipids and chlorophyll from a crude extract. I'm thinking of taking a glass jar and drilling a hole in the lid and throwing away a can of butane, dropping my oil and preparing it for winter and filtering it with butane. Winter preparation is used to refine several types of products, including cannabis concentrates. If you can't find iso or ethanol, take a look at this, I'm not sure if it's shipped to MI, but it's supposed to be 100% ethanol (200 degrees), so it would work well for your winter preparation.
The amount of time it takes to perform the purge process depends on how much oil you are preparing for winter. However, high temperatures can be avoided in preparation for winter by using a rotary evaporator for the solvent purging step. Certain winter preparation methods may end up losing much of the terpene concentration due to the higher boiling point of ethanol compared to butane or propane, which are commonly used during dewaxing. When deciding whether to prepare or dewax a product for the winter, an extractor will need to weigh several factors, including the level of lipids in the concentrate (and the benefit they'll gain from eliminating them) and how the extract will be consumed.
The preparation product for winter is not always an oil and this stage can be used in the processing of other forms of concentrate, such as shredding and breaking. Winter preparation is the process of removing all residues, solvents, waxes and fats from the final product using ethanol to create an “absolute product”. Thank you very much to me, I was also looking for the step-by-step preparation for winter and so far it has been the way you show yourself and I want, but one thing you change as you would if you weren't preparing for winter and, if so, how many hours apart, thank you for what you do. Winter preparation with cold ethanol is generally preferred, as it is relatively cheap and quick, but tends to produce darker extracts.
