If you are in the adhesives industry, the word ‘rosin’ is no new word. I am confident that you have seen some yellow-brown liquid of sought, that is quite thick and resists flow; often appears like glue. You may be feeling a bit confused after this description, but I am confident that with time and an online search here and there, you will come to grasp fully. Well, I will have you know that which I speak of is rosin. Rosin finds its primary use in making adhesives and in the treatment of the bows of stringed instruments like violins and guitars. 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. What you will be looking for is a rosin press machine, and there exist many different kinds 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.
You begin by first assessing the plates the machines uses for pressing. You need to have long and narrow rectangular plates if you want to maximize the production from the extraction procedure. 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. 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.
Lastly, make sure you consider heating factors. 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. By making sure that heat is distributed evenly, you can keep heat from causing damage to the rosin. 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.
