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 seen some thick, translucent viscous yellow fluid that has glue-like properties, in a varnish factory maybe? 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. 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. 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. 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.
You begin by first assessing the plates the machines uses for pressing. 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. Having a greater perimeter means that there will be more room through which the rosin can escape once pressed. Again, narrow plates will allow for the distance between the center of the bag, containing the material, and the edge of the bag to be minimized. This means that the rosin will travel a shorter distance once squeezed out hence fewer chances of degradation due to heat.
Next up is the subject of pressure to be addressed. Most people live by the belief that the more pressure you pump in, the better or more rosin they will get. The above concept is wrong because the pressure applied will rely heavily on the kind of stuff being pressed, its growth process and age. 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.
Finally, look into the issue of heat. The matter of heat can’t be understated since you can’t do without it yet in excess it cause more harm. The goal is to ensure that you have even heat distribution. Recall it is the heat that lowers the viscosity of the rosin so that it flows. The point at which you position the heating coil in the plates will dictate heat distribution. 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.
