If you have ever dealt in adhesive before, then the term ‘Rosin’ is a familiar one. Have you ever come across a certain translucent golden yellow sticky glue-like fluid? The above may not be a detailed characterization of what I’m precisely talking about, but it will help you get a vivid understanding for now. That yellow liquid that is entirely unpalatable to some, by the way, is rosin. As unpleasant as it may seem to some, rosin has extensive uses in making adhesives, inks and treating the bows of stringed instruments such as violins. Now that you can vividly see its vitality, you may want to start doing the math of how to capitalize on it by getting a press machine to extract it. You will go out to look for a rosin press machine, and you won’t have to look far to find one. Using this article, you will figure out what mechanical factors need to be adhered to when picking a rosin press machine.
The first technical parameter has to do with the rosin press machine plates. The machine of choice should have slender plates which are long and rectangular. To improve the perimeter to area ratio for better extraction, a rectangular plate will do wonders. A large perimeter becomes crucial as it affords the greatest space by which the rosin can escape. Narrow plates effectively reduce the distance between the center of the pressing bag and the edge of the bag which the pressed rosin has to cover. This, in turn, reduces chances of heat degradation of the rosin.
The other fundamentally important consideration is pressure. Most people live by the belief that the more pressure you pump in, the better or more rosin they will get. This is a misconception since the pressure is affected by many things including material being pressed, humidity, and quality of the growth process and age of the material. Excess pressure can result in plenty of lipids and unwanted pigments ending up in the rosin which reduces quality. You should go for a rosin press machine with solid construction in terms of sustaining pressure within the desired range throughout the extraction process.
Take time to think about how the heat will affect your rosin quality. This is a great issue since the extraction can’t be efficient without heat, while at the same time excess heat causes massive degradation of the rosin. The goal is to ensure that you have even heat distribution. Heat cuts down on the viscous effect, hence allowing the rosin to flow. The secret is in the positioning of the heating coil in the plates. Therefore, before purchasing the rosin press machine, discuss with the seller as to where the heating coils have been placed and whether these positions will bring about even heat distribution.
