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? This may not be an accurate description of what I’m talking about, but it will do for now. My point is, that liquid is, in fact, rosin. They say good things tend to come from some bad sources in some cases, and as unpleasant as rosin is, it is widely used in making adhesives and inks. So being such a useful commodity, you need a machine that can easily extract this rosin without making a massive mess all over. What you will be looking for is a rosin press machine, and there exist many different kinds in the market. This article is your gateway to finding out what to look for in a rosin press machine in terms of technical capabilities.
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. For starters, you will enhance the perimeter to area ratio by using a rectangular plate. 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 means that the rosin will travel a shorter distance once squeezed out hence fewer chances of degradation due to heat.
Secondly address the issue of pressure. A majority of people want to apply intense pressure then expect to get the best rosin out there. 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. Overdue pressure will push specific unwanted lipids and pigments into the rosin hence affecting quality. Considering this, the rosin press machine you go for, should have a pressure gauge and an accompanying regulator to ensure that the required pressing pressure is maintained.
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 is responsible for causing rosin flow by reducing viscosity. 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.
