Combustion methods have been very popular to consumer herbs in the US. However, in the last two decades, the demand for vaporization has increased a lot. Many smokers are attracted to dry vaporizers now, as researches show that it is one of the healthiest methods of smoking when compared to the traditional ways.
Researchers believe that burning cannabis can result in the production of toxins, which include even carcinogens, which can affect the human respiratory system. On the other hand, vaping is a smokeless method in which the dry herb is heated at lower temperature to release the terpenes and other active ingredients into a vapor. Vaping will not result in the production of any harmful byproducts.
Working of Herb Vaporizers
Herb vaporizers make use of one of the two types of heating mechanisms to extract the active ingredients and convert them into inhalable vapors. Studies show that active elements in the plant matter will start to vaporize at around 284°F and the combustion will start at around 446°F. Vaporizers are capable of offering temperatures between this range, and some of them allow users to control the heat and temperature. This can help control the quantity of terpenes and active ingredients that are released while vaping.
Types of Vaporizers
A dry vaporizeris available in varying shapes and sizes. The large and stationary type vaporizers usually make use of two delivery systems, bag style and whip style. “Whip” is the term used to refer to the tube that connects the mouthpiece and the vaporizer, whereas bag style vaporizer features a food grade “bag” or “balloon” at the heating chamber. When used the bag is filled with vapor and works using a built-in fan.
Dry vaporizers make use of two heating methods – conduction and convection. A conductive dry hear vaporizer operates by placing the dried extract or flower on a surface heated electronically. The surface can be a metal or screen, which is usually called as the “hot plate.” The plate is then heated to the ideal temperature to vaporize the herb, by directing heat throughout the chamber to convert the terpenes and cannabinoids into vapor.
In the convective heating method, the product does not come in direct contact with the heating element. After the air reaches the ideal temperature, it is moved to the herb by a fan or by inhalation and the air heats either the concentrate or flower converting the active ingredients into vapor. The advantage of this method is that charring of the surface is avoided. Usually, ceramic material is used to make the heating element, whereas some herb vaporizers use stainless steel material as well.
