I am confident that the word ‘rosin’ is one you have come across severally, especially if you have dealt with varnishes and adhesives before. 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. 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. So being such a useful commodity, you need a machine that can easily extract this rosin without making a massive mess all over. Such a device is called a rosin press machine, and there exists plenty of such in the market. This article is your guide through some of the technical considerations that you need to examine before you go about purchasing 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. With rectangular plates, you are able to maximize the perimeter to area ratio. A large perimeter becomes crucial as it affords the greatest space by which the rosin can escape. By using narrow plates, the rosin pressed out will move through a smaller distance from the center of the bag with the material to the ages. This, in turn, reduces chances of heat degradation of the rosin.
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 not wise since the pressure element is dependent on moisture, and the age and type of material being pressed. Overdue pressure will push specific unwanted lipids and pigments into the rosin hence affecting quality. In line with this, you need a rosin press machine ingeniously designed to monitor pressure and keep it within the required range.
Lastly, make sure you consider heating factors. The matter of heat can’t be understated since you can’t do without it yet in excess it cause more harm. To get this right, there must be even distribution of heat. 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. You need to consult closely with the press machine seller to confirm that the heating coil placement will ensure even heat distribution throughout the extraction process.
