Rosin is the concentrate and oil that can be obtained when cannabis is subjected to high temperature and pressure. The high temperature required in rosin press extraction is to make the oil liquid while the pressure being exerted is to mobilize the oil extract and the filter brings the separation of oil from the rest of the cannabis material.The process of rosin extraction liquefies and pushes out the trichomes and cannabinoids out of the cannabis material under the pressure and temperature. Rosin press extraction is actually one of the simplest extraction methods of getting oil from cannabis. Compouds such as cannabinoids and terpenes are contained in the oil, shatter and butter that are produced by the trichome heads when they rupture under pressure and heat.
Due to the uniqueness of rosin extraction, it more often involves a series of wide experimentation with the key components before the desired final product is created. You have to actively explore a number of ways of extracting rosin in order to gain sufficient control of the entire process and develop consistency in the process of cannabis extraction. Thorough experimentation is needed when using the method because of the influence each element has on the final product quality and constitution.If you want to have more control over the influence of the elements, you should not use a primitive device to extract the oil from the cannabis.
Rosin press extraction depends on pressure and temperature to extract oil without using solvents. Essentially the water content within the flowers works to decrease the oil viscosity making it to flow with more ease.
Rosin press extraction is one of the recent innovations in the cannabis industry and the method is being improved with time through experimentation.
If you want higher yields of the oil extract, you should maintain the humidity of the flowers at roughly 60% to prevent the oil from soaking and being absorbed into the plant material. Temperature is an essential component of rosin extraction which ensures the consistency of the process and should, therefore, be kept at the optimum level. The the temperature to be used for rosin press extraction should be around 150 F at the minimum and 230 F at the maximum beyond which important compounds in the cannabis material can be damaged.
More pressure does not mean more oil yields when the recommended levels even though the pressure is the basic component of rosin press extraction. A pressure of about 550 PSI to 1000 PSI is needed for optimum oil yields from the extraction method.
Time taken for the extraction to be completed and the quality of the plant material also affects the quality of the extracted rosin. The use of the balanced optimum conditions, quality cannabis and relatively shorter time ensure a quality end product.
