What is a pile driver, All knowledge points?

A pile driver (also known as a pile driver) is used to drive piles into the ground to form the foundation that supports buildings and other large structures.

How a pile driver works
There are two main types of pile drivers: conventional pile drivers and vibratory pile drivers (careddi pile drivers product lists).

Conventional Pile Driver
A conventional pile driver works by using a weight placed over a pile that is released, slides vertically downward and strikes the pile, hammering it into the ground. The weight is mechanically lifted and can be driven by hydraulics, steam or diesel. When the weight reaches its highest point, it is released. Gravity causes the weight to drop, dropping it onto the pile. The impact of the weight on the pile hammers it into the soil. The process is repeated until the pile is completely driven into the ground.

Vibratory pile driver
Vibratory pile drivers (also called vibratory hammers) use a rotating counterweight to create vibrations that cause the pile to “cut” into the soil below. While a conventional pile driver works like a hammer and nail, a vibratory hammer works more like an electric knife that cuts through meat. The high speed vibration loosens the soil and makes it easy for the pile to slide into the ground.

The Need for Pile Drivers
Not all construction projects require pile driving or pile drivers. Foundations are only necessary when the soil cannot support the weight of the structure being built. This can happen if the construction site has a soft layer of soil on the surface to the extent that the soil cannot support the weight of the new structure. Likewise, if a particularly heavy building is being constructed, the surface soil will not be able to support its weight. In both cases, foundation piling can be used to transfer the weight of the structure from the surface of the soil to the stronger soil or rock below.

Types of pile drivers
Diesel Impact Hammer
A diesel impact hammer (also known as a diesel pile driver or diesel pile driver) is a traditional pile driver powered by a large two-stroke diesel engine.

Steam Impact Hammer
A steam impact hammer is a conventional pile driver powered by compressed air or steam.

Hydraulic Impact Hammer
The hydraulic impact hammer is the third type of conventional pile driver powered by a hydraulic system. Hydraulic impact hammers are considered to be more environmentally friendly than diesel hammers.

Vibratory Hammer
Unlike conventional pile drivers that use large weights to drive piles into the ground, vibratory hammers use vibration to slide the piles into the soil as well as to pull old piles out of the ground.

Noise Precautions
Conventional pile drivers that use heavy weights to drive piles into the ground can have noise pollution problems. The primary noise emitted by pile drivers is caused by the impact of the hammer hitting the pile or by collisions between hammer components, and can be disturbing to people and wildlife. Vibratory hammers, on the other hand, are relatively quiet because they do not use a hammer weight system.

How Changes in Cannabis CO2 Extraction Technology Have Significantly Improved Its Productivity

It’s a controversial claim: properly processed CO2 can meet or exceed the throughput rates typically seen in ethanol extracts.

I got my start in the cannabis side of the industry. I was the original manager of the Charlotte Web CBD Extraction Lab, which provides extracts to children with epilepsy. We started with ethanol and after about six months, we decided to bring supercritical CO2 on board (careddi Supercritical CO2 Extraction machine product lists). It changed the way I looked at my job.

I met Dr. John MacKay from Waters, who pointed me in the right direction in terms of peer review and background on how to properly develop methods. I then took it from the cannabis industry to the recreational cannabis side through Willie’s Reserve.

In my experience, the biggest challenge with using CO2 as an extraction solvent is properly understanding the flexibility it offers in terms of targeting specific compounds or specific analytes in the plant matrix. It has the ability to extract or leave behind many compounds – something that ethanol-based or even light hydrocarbon-based extracts cannot do. Because of this property, the opportunity for extraction efficiency is tremendous.

There are also misconceptions about the possible throughput of supercritical CO2, which can be traced back to the methodology and the way some current equipment is built. Most extraction managers can get the results they want relatively quickly with some proper training and knowledge. But there is another level of knowledge that can push the possibilities of this solvent into uncharted territory. That’s where I want this community to go.

For example, one of the big selling points of ethanol extraction is the ability to get high throughput. However, any ethanol system you use will need to be winterized, either inline with the equipment or downstream in the line. This requires a significant capital outlay for equipment and it adds labor and time (usually several days) to your process.

Based on my experience and the data I have collected, if we start with the industry standard CO2 extraction method on the equipment we normally use, there is room for up to a 4x productivity gain through method changes alone – while maintaining a very high purity crude oil.

I have developed a method that does not require freeze-proof equipment and flammable solvents. If you want a high quality distillate as the end result, you can use a CO2 extractor (careddi Supercritical CO2 Extraction machine product lists) with your method, and you can go directly from the extractor to the distillation equipment without a time-consuming process.

Another big problem in the extraction equipment market is that manufacturers will claim increasingly higher solvent flow rates, and this seems to be a selling point for those who have not used this technology before. In fact, many of the systems on the market have solvent channeling problems because the flow rates are so high that the channels reduce your efficiency and therefore, at the end of the run, you’re throwing away material that’s full of THC and CBD. That will cost you money.

My future research will focus on determining the details of the solubility of all analytes, whether they are cannabinoids, small amounts of cannabinoids, or monoterpenes, and start plotting densities as they reach maximum solubility. Because at some point that will be the best approach for product X and find that you really have to find the maximum solubility of some of these target analytes and that simply isn’t done.

When that’s done, I would like to see on all future CO2 machines some capability to track not only the density in the extraction chamber, but also the density in the fractionation vessel after the extraction. That’s something that’s missing and it’s definitely a key component to running a proper CO2 extraction.

We are on the cusp of some major discoveries in the field of cannabis extraction, and I’m happy to do my part to bring them to the public. But the extraction manager community, and the businesses that depend on us, will only succeed when we all learn to move away from some of the default thinking that drives machine buying decisions today.

How is CBD oil made?

You may be aware of the various health benefits of CBD oil, but most of us know very little about the production of this substance and what we should know before we choose to use the product. Whether ingested or used topically, CBD oil is made using several different processes. To boot, it can even be different colors and contain contaminants, depending on the way the cannabis plant used to make it is grown.

As you can imagine, these are all important considerations before making a purchase. Here’s a look at how CBD oil is made and what to consider when evaluating CBD products.

CBD Whole Herb Extraction Methods
When looking at how CBD oil is manufactured, one method is called “whole plant extract” (also known as “full spectrum”). This means that when the oil is made, it contains not only CBD, but also certain levels of THC, as well as other cannabinoids and terpenes from the cannabis plant, which are anti-inflammatory agents in the plant. Often, the whole plant is the more popular choice. Studies have shown that full-spectrum CBD oil is more effective than isolated CBD oil when it comes to treating inflammation (more on this later).

 

Isolation Methods
In contrast, the isolation method means that the extracted CBD oil contains only CBD (i.e., no terpenes, fatty acids, or other cannabinoids). Some people may prefer this method for a simple reason: because it doesn’t have any levels of THC, CBD oil produced by the isolation method can be considered a lower-risk option for anyone who doesn’t want to use THC in their system. (This is highly unlikely, but isolation may be a good option for those who are very cautious.)
Carbon Dioxide Extraction
To make the oil itself, the supercritical CO2 process (Careddi link for more info) is the most expensive and purest method. This new process uses liquid carbon dioxide (rather than chemicals) as a solvent, and it is commonly used in other commercial extraction processes in the food industry, especially for making coffee and omega-3 oils.

 

Ethanol extraction
This extraction method is the most common. Basically, ethanol is used as a solvent to remove CBD from the cannabis plant. The advantages of this are that it is fast, uses less electricity than the CO2 method, and requires inexpensive equipment. The downside? Ethanol is very flammable, so certain precautions need to be taken with this process.

 

Color Options
In addition to the way the CBD oil is made, the color can vary, depending on the type of oil. Filtered oil is yellow or gold in color and is considered to be of the highest quality (meaning it can also be more expensive). Decarboxylated oil is heated to “activate” the healing properties of CBD and is known for being extremely effective. It is usually more of an amber or brown color. Crude oil is usually dark or greenish because it is not filtered and still contains plant fiber and chlorophyll.

 

Things to Consider Before Buying
The most important factor when choosing CBD oil is not necessarily the way it is made and the process by which it is used. The most important thing is how the cannabis plants are grown and what contaminants, if any, they contain. While several states have legalized CBD, there are still very few regulations to protect consumers. Knowing if topical application or ingestion is right for you, how much THC and CBD is in the product, and what testing has been done on the final product are some of the key things you should make sure you know before choosing CBD oil.
