Dry Herb Vaporizer Technology: What is it?
“A dry herb vaporizer is a heating appliance used to warm plant oils (from their raw plant material form) into gas vapors. Dry herb vaporizers help resolve issues related to combustion by offering a reduced-harm inhalation method. The user inhales and draws the vaporizers’ heated air over the plant material without igniting, releasing the active compounds in a vapor that is relatively free from the byproducts of combustion.”
Steven’s Background 00:54
- Steven’s father invented an induction heating tool in the automotive industry.
- Steven helped his father found and grow the company for over 15 years.
- Steven’s expertise is in thermal technologies and product development.
- Steven was also involved in another company that built circuit boards for Motorola and Kawasaki.
Steven’s Journey to Cannabis Vaporization 01:55
- Steven’s customer came to them with the idea of making an induction heating vaporizer.
- Induction heating is an electromagnetic technology that only works with ferrous metals.
- Over the years, Steven started thinking about getting into the cannabis industry.
- Finally, Steven moved forward and looked more into the thermal technologies for vaporization.
Induction Heating Technology 02:11
- Induction heating is a technology that heats up metal on body parts of vehicles for removing parts.
- It can heat up metal parts like the windshield, body side molding, decals or even a frozen nut cherry red in about 15 seconds.
- Induction heating is not great for cannabis vaporization.
- Induction heating is inefficient for vaporization because you’re still transferring the heat from outside.
- The heat transfer can be done much less expensive than induction heaters with a regular resistance convection heater.
- The product developed by Onsen Labs is not an induction heating product.
Convection Heating Vaporizer 05:42
- The product developed by Onsen Labs is a wind and whip vaporizer.
- It is not an induction heating product but a convection heating vaporizer.
- Convection heating vaporizer heats the air, heating the herb instead of conduction heating.
- Conduction heating is much less efficient, and it heats the herb in direct contact, leading to overheating, burning, and uneven heat.
- The walls of the wand get hot, and then the heat is transferred to the herb.
- The bulkhead of energy is created by convection heat.
Vaporization vs Smoking 07:48
- The traditional way of consuming weed is by smoking it, but when we light it on fire, it reaches about 1200-1400 degrees which destroys a lot of the plant, and causes irritation in the lungs.
- Conversely, vaporization heats the weed at a lower temperature of about a thousand degrees, boiling off the compounds instead of destroying them. This provides a fuller profile of compounds from the plant compared to combustion.
Temperature and Vaporization 08:59
- Temperature is a very specific and independent question regarding vaporization, as the temperature relates to what compounds are being released.
- The temperature range that a person will want will be very specific and independent. Even in the future, it will probably be a discussion with a doctor or primary care specialist.
- The temperature range is specific to each individual and their needs.
Temperature Zones 09:24
- Temperature zones correlate with temperature zones they’ve tested in the lab.
- Each unit is tested and provided a thermal performance certification so that the person knows what temperatures are reached inside the chamber.
- The temperature sensing is different in the product’s design because the sensor is not the same thing as organic matter that they’re heating up.
Analog Vaporizer 10:41
- The technology in the marketplace can be confusing and complicated, but analog vaporizers are simple and have temperature zones that are great for patients or any consumer.
- It can get confusing, but with an analog vaporizer, you just need to medicate, and you’ve got a range, and it’ll do.
- People get different effects at different numbers, and it’s a very specific and independent question that a person has to answer for themselves.
Vaporizer Pens 12:29
- Vaporizer pens have a thermal profile unique to the materials used in them, and the way they hold the thermal energy and release it will produce a different graph regardless of the product.
- The effects a person wants to feel or need for their health conditions are specific to them, and it’s not a one-size-fits-all.
- The disposable cannabis pens or carts can be very restrictive and almost give anxiety when pulling on them.
- There are levels to vaporizers, and people are learning more about them, including e-cigarettes, disposable cannabis pens, handheld devices, and desktop vaporizers.
Vaporizer Categories 14:46
- A vaporizer is a device that takes a liquid form of an oil and boils it into a vapor for inhalation.
- E-cigarette vaporizers are technically vaporizers.
- A vaporizer is more or less used to describe a cannabis vaporizer.
Vaporizer Materials 15:45
- The materials used in vaporizers is a focus point for improvement in the marketplace of vaporizers.
- Older pens all used a metal filament, which would get red hot and produce a metallic taste.
- Nowadays, they have more ceramic ones.
- Metals inside their hot zone get hotter and start to release byproducts.
- Inert materials like titanium are also used but is also an environmental description.
Inert Materials 17:42
- Inert materials do not react with other substances and do not produce harmful by-products.
- The element and element stand in the vaporizer should be made out of inert materials to prevent additional flavor into the herb.
- The materials are divided into two parts, the element stand and where the ceramic connects into the base.
- The product developer is responsible for designing the product specifications and how they use those materials.
Ceramic Material 17:34
- The element and element stand both pieces are made out of ceramic.
- Luminous ceramic al2o3 is an inert material.
- In a vacuum, it’s an inert material, so there is no byproduct and flavor added to the herb.
Design Specification 19:18
- It has to do with the design specifications of the product developer and how they use those materials.
- The element stand in other products was getting about 350 degrees, so the materials needed to be expanded.
- The temperature of where the ceramic connects into the base is below 100 degrees.
- The outgassing from those types of materials at that temperature is not different from what you get in your home with other products.
Ceramic vs Titanium Heating Elements 20:33
- Titanium heating elements release byproducts if heated beyond a certain point.
- Ceramic heating elements do not release any byproducts, no matter how hot they get.
- Ceramic heating elements are reinforced with design specifications to ensure safety.
- The temperature threshold for ceramic heating elements is around 3,000 degrees Fahrenheit.
- Products with ceramic heating elements are heated to 1,200-1,500 degrees Fahrenheit.
- Overheating any product can cause it to release harmful byproducts.
Flavorful Vaporization 22:51
- Vaporization produces a different flavor compared to smoking.
- Dry herb vaporizers don’t destroy low boiling compounds like beta-pinene, giving cannabis a more flavorful taste.
- Different terpenes in cannabis produce different tastes and flavors.
- Vaporization allows users to explore and play with different temperatures to tailor their experience.
- Vaporization produces a subtle, gradual increase in high, rather than hitting a wall like smoking or dabbing.
- New users should start with a dry herb vaporizer and go low and slow to avoid overdoing it.
Inhalation Safety 22:06
- There needs to be more study on the long-term effects of inhaling and consuming fumes from heated metals.
- There are anecdotal cases of health concerns about inhaling fumes from heated metals.
- Vaporizers with ceramic heating elements eliminate the risk of inhaling harmful byproducts.
- Patients should look for products that prioritize safety and avoid devices that can overheat metals and produce harmful gases and fumes.
About Onsen Labs 26:44
- Onsen Labs is a company that works on vaporizer technology.
Onsen Labs’ journey 26:46
- Steven has been working at Onsen Labs for three years.
- Steven has been working on the company and its brain from its development to where they are today.
- The interviewer asks Steven where they started three years ago and where they are at today.
- Steven mentions they are moving to a distribution model due to the PACT Act passed in December.
- The PACT Act affects their ability to ship vaporizers directly to consumers, so they are setting up distribution to sell through a high sales volume.
The PACT Act 27:04
- The PACT Act was written and intended for e-cigarette vaporizers, but it was written so vaguely that it affects all types of vaporizers.
- Steven mentions that the PACT Act is a double-edged sword, it’s good and evil.
- They are now moving to a distribution model and setting up distribution due to the PACT Act affecting their ability to ship vaporizers directly to consumers.
