Vaporizer are the only way to turn a solid to a gas without setting fire to it and who wants to burn???
A vaporizer is an instrument that enables a user to inhale a commodity normally of a blend or herb variety. Its principle is that it heats a compound that produces a vapor which in turn can be inhaled. This is unlike smoking, where a product is ignited and directly taken into the lungs. Vapor contains no tar and very little carbon monoxide and vaporizers make use of glass or metal chambers that can extract unwanted vapor. This vapor can be collected and saved because no smoke is produced and due to this the desired effect can be achieved by using much less material. Therefore, the harmful effects that are associated with smoking are drastically cut down as is the side effect of passive smoke.
Vaporizers come in a variety of packages from a basic model to one that can cater for all of its users needs. Their major component is the heating element that is normally controlled thermostatically. The heating process can be carried out in a number of ways either by convection, radiation or conduction.
Convection vaporizers make use of a heating element forcing herbs and air through it. This is a more modern principle and the air is inhaled without the help of a pump or fan and most modern day vaporizers make use of this form of vaporization.
Radiation ensures that the temperature of a substance rises when radiant energy is absorbed. The required energy can be produced by a source of bright light like the sun. This can be achieved by making use of a magnifying glass on a sunny day. This process for producing vapor ensures that no dilution takes place and a higher quality of vapor is often produced.
Conduction vaporizers are the oldest and original design. This principle makes use of a metal plate and the required blends or herbs are placed upon it. The plate is then heated to give off the required aroma.
The Quality of Vapor
Very few reviews or studies that have been carried out have concentrated on the quality of vapour that is produced. More emphasis has been placed on the way a vaporizer is used. Many vaporisers can be slow in delivering the required result. This is due to the fact that aromatics are released too early and has an effect on the quality of the vapour. The problem has been overcome by the introduction of a bowl known as a chamber bowl and this promotes the delivery of a more enhanced vapour with a higher consistency and concentration. Many modern pipes can be modified to take advantage of this update. A slower rate of extraction is experienced when using the bag capture type of vaporizer.
Intensive studies have revealed that the use of a vaporizing device does not expose the user to any harmful products. Although likened to smoking due to the effects that can be obtained by its use, there can be a therapeutic effect gained by continuity. It should be stressed that these results were confirmed when only small amounts of an ingredient were used.
As early as 1996 tests were carried out to determine the advantages of the use of vaporizers as opposed to the use of filtered or unfiltered cigarettes. There were two vaporizers used in this test; one being a hot air gun type that was home made and an electric hotplate version. The results concluded that the vaporizers were 25% more effective in their performance than unfiltered cigarettes. This test also confirmed that pipes and filtered cigarettes performed worse than unfiltered ones by a rate of around 30%.
The many studies carried out have not examined the presence and volume of gases like carbon monoxide but have confirmed that vaporizing represents a substantial decrease in the presence of them.
Respiratory irritation that can result in bouts of coughing is not completely eliminated by using a vaporizer but when compared to smoking, it is greatly reduced. Inhaling a large amount of a vaporized mixture could result in coughing but when moderation is practiced this can be virtually eliminated. This can also be removed by moisture conditioning and by making use of water or ice to cool a substance. This process allows a vapor to pass through a water pipe or a particular tool that uses ice and can produce a vapor that virtually eliminates irritation when a user takes larger inhalations.
Effectiveness of Vaporizers
There are a number of factors that must be taken into account when experimenting to find the ideal vapor that suits a particular individual. Everyone has different requirements just the same as smokers have varying tastes when choosing a cigarette type. The number of variations that can be obtained are endless and by altering the water or essential oil content or changing the materials consistency in the filling chamber. So experimenting with different temperatures and specimen densities and vapor storage times can help. By trying out the endless preparations that are available, the permutations are endless and even the experimental aspect of vaporization can be rewarding.
Due to the vast amount of variations available, it is obvious that many have not been scientifically tested or proven. However, research has confirmed that vapor efficiency is at its highest when delivered in the region of 226 degrees C. This reduces by 50% when the temperature falls to around 150 degrees C. The highest efficiency produces the purest of preparations. Also more vapor is lost through condensation the longer it is stored; just a few minutes will be minimal but a 50% loss will be experienced after about ninety minutes. Further studies revealed that up to forty percent of vapor inhaled was not absorbed into the lungs but just exhaled.
Food Enhancement with Vaporizers
Some chefs make use of vaporizers to apply heat to some herbs and spices which has been proven to release unique flavours. This can add certain individuality to an otherwise ordinary tasting meal. Some upmarket restaurants have been known to use aroma filled bags as place mats and when a plate is placed on them they puncture releasing a pleasing aroma.
