Let Entrepreneurs Do More Than Dream

... And understand why we are giving away a T50 Ointment Mill. 
Starting up a business is getting harder. Young entrepreneurs who lack in real world business tactics oftentimes face various challenges and need more supports from successful entrepreneurs. The CEO of my company, Ken Kuang, recently published an article in the Wall Street Journal about this critical issue and has received overwhelmingly positive feedback (Read more:http://on.wsj.com/1hJtNKo).
He talked about the disbanding of the Moxie Center at UC San Diego, which was designed to fund students and help them pursue their early entrepreneur dreams. In his opinion, the Moxie Center failed to teach its budding entrepreneurs the two most basic survival skills for startups: understanding the concept of “win-win” and how to forecast profits and losses. Besides seeing it as huge regret, he has revealed the fundamental reason of Moxie’s downfall. It was due to a poor business model embedded with no returns on investment and lack of start-up support.
Here, we are living by his ideals. And here is how we decided to help those looking to start up a compounding pharmacy or those looking to find the right tool for their next big idea. Torrey Hills Technologies is giving away a free T50 ointment mill in September. Businesses can easily participate by clicking this webpage http://www.threerollmill.com/ointmentmillgiveaway.html, and simply fill in four multiple choices questions by September 14.
You may think to yourself “how is this a return on investment?”  By giving away this award-winning machine to our winner, we can help them with their very first step of pursuing their dreams of starting up a business. When they grow, we welcome them to turn to us for future needs. The initiative also helps build a strong bond between us and the pharmacy compounding community. That would be our return on investment. Overall, it is up to the lucky entrepreneur that wins this machine to decide what they do or if they succeed, but we are here to help give them the seeds to grow themselves.

Creams Splashing Out Of Your Ointment Mill? You Can Stop It!

Do you sometimes find it annoying when creams splash out of your ointment mill? Just follow the tips below to check for possible causes. It is a problem rather easy to prevent.

1. Set suitable gap sizes.

Usually the speed of the front roller is much faster than that of the rear roller. In order to balance input and output, we recommend setting the rear gap size larger than the front gap size. However, if the rear gap size is too much larger than the front, it might lead to a larger input than output. As a result, the creams will splash out of both sides of the rear gap. For THT’s T50 ointment mill, an ideal gap setting would be “1” for the front roller and “3” for the rear roller.

2. Check the condition of the plastic guides and the scraper.

If the plastic guides are not sitting on the rollers properly, there will be tiny gaps between the guides and the rollers through which the cream may leak. Likewise, if there is a gap between the front roller and the scraper, the cream cannot be collected sufficiently, which again leads to a larger input than output. So always check the plastic guides and the scraper before running the mill.

3. Lower the speed if necessary.

When running at full speed, the ointment mill is able to process more of your product in a given time period, meaning higher output and better productivity. However, thin creams tend to splash more easily, because they could not adhere to the rollers as firmly as the thick ones do, especially when the rollers are rotating at a high speed. Therefore, slowing down the mill could reduce the risk of splashing in some cases.
Just a few simple steps could help reduce waste and make compounding happier. Everyone could become an expert running an ointment mill!

Three roll mill processing nano material - we were cited in many papers!

Our lab model three roll mill is the perfect choice for the processing of nano materials. Particles are thoroughly and uniformly dispersed. Here we have a selected few of papers to make our point.

___________________________________________________________________________

Summary:
Scientists from both the Department of Electrical Engineering at the University of California and the Advanced Material Research Center at the Samsung Advanced Institute of Technology have discovered that three roll milling yields advanced electromagnetic interference shielding for carbon nanotube (CNT) composites. These researchers used a Torrey Hills three roll mill to guarantee successful assimilation and distribution of intertwined multi-walled carbon nanotubes (MWNT) in their polymer matrix. A stable and even dispersal is essential in achieving maximum efficiency in electromagnetic shielding for CNT/polymer composites.

Summary:
Carbon nanotube (CNT) and polymer composites are very important to multiple industries, including aerospace, energy, electronics and many more, due to their strong durability as well as superior electrical and thermal conductivity. A Torrey Hills three roll mill was used to disperse dry CNTs into a silicone resin, so that researchers could compile orientation and dispersion indices with an image analysis technique. These indices will allow the properties of CNT/polymer composites to be more easily predicted, so that their microstructure can be optimized.

Summary:
In a study aiming to compare nanocomposites made with volatile solvents to silica nanocomposites made with a room-temperature ionic liquid (RTIL) preparation strategy, researchers in the Department of Chemical and Biological Engineering at Drexel University adjusted a Torrey Hills 2.5 x 5 three roll mill lab model to the precise specifications needed (a gap of 20 microns between the 2.5’’ diameter rollers, and a surface speed of 31, 84 and 174 RPM, in this case). The RTIL nanocomposite preparation proved to be an effective alternative, which may help improve the structural strength and electrical conductivity of thermosetting polymers, such as epoxies.

Summary:
Researchers used a Torrey Hills three roll mill to disperse surface modified and unmodified carbon nanotubes (CNTs) into an RTM-grade (resin transfer molding) epoxy resin. They discovered that dispersing C100 nanotubes by three roll milling led to increased electrical conductivity in the final composite structure. This exciting research will help improve aerospace grade composites so that they have superior electrical capabilities.

Summary:
Aiming to investigate how to best transfer the valuable properties of carbon nanotubes (CNTs) to polymer nanocomposites, researchers from the Composites Centre at Cranfield University milled dry C100 nanotubes and surface activated nanotubes into a resin with a Torrey Hills three roll mill, so that Resin Transfer Molding (RTM) could be performed afterwards. Studying the RTM of glass and carbon epoxy composites that contain dispersed carbon nanoparticles has helped scientists understand that CNTs must be consistently dispersed into a homogeneous polymer in order to best yield high electrical conductivity and advanced thermal properties.

When and Why Do I Need Cooling for Three Roll Mill Rollers?

A client who intends to use three roll mill for algae exfoliation visited our lab the other day, trying to process several kilos of algae harvested from the Norwegian sea. We seldom use our demo lab model to do large samples like that. However, they explained that only a small amount of oil can be extracted and they need a significant amount to test the results. For such a novel application, we gladly agreed.

As the milling went along, the rollers, which are made from stainless steel, got warm and raised the concerns of our client. They want the rollers to stay below 40°C to prevent the algae material being oxidized. And we had to turn on the cooling system, which can maintain the roller temperature ±2-3°C around ambient temperature.

It is very common for rollers to get warm after a prolonged period of continuous running. The roller surface temperature increases as a result of heavy friction between the rollers brought by the high shearing force necessary for successful grinding. When the surface temperature exceeds 70°C, damage to the gear system might occur. Under such circumstances, active water cooling is recommended. If, in this customer’s case, a certain temperature is required to prevent deterioration of the material, water cooling is of utmost importance as well.



The mechanism behind water cooling is not a complicated one. As you can see in the illustration above, water is first pumped into the built-in water tank on the machine, usually with a submersible type pump (so that it can be placed in a larger water container for recycling). This cooling water goes in through the pink tunnel and flows into the blind hole inside the roller. The blind hole is designed with a slight slope so that water eventually flows back into the water tank. There is a water outlet through which warm water gets out of the tank. The water recycles in and out of the larger water container, such as a bucket, and does it job keeping the desired temperature. Be sure to adjust the water flow by controlling the pump to keep the liquid level constant in the water tank. The same system can be used to heat up the rollers if hot liquid is pumped into the rollers. 

Last but not least, although we call it water tank, water is not the most desired liquid for the job. We recommend the use of at least 50/50 coolant and water. Coolant with anti-corrosion additives, such as this one, includes a corrosion inhibitor that balances the negative acidic effects that can develop over time in antifreeze and water solutions. It also stabilizes the pH level which helps reduce rust and prevents electrolysis, mineral deposits and pre-existing scale build-up from forming resulting in potential core damage for long term protection.

Maximize Ointment Mill Throughput

Topical formulations greatly reduce the risk of side effects caused by oral medications, offering the potential to deliver at the site of inflammation while minimizing systemic concentrations. As a result, the demand for pain creams has increased significantly. One pharmacy asked us to help optimize the output of a lab model ointment mill they bought from us, hoping to make 80kg of creams daily. 

What we thought would be a simple task of adjusting the speed or the gap sizes turned out to be a full-scale lab experiment. The ointment pre-mix was so thick that it required an unusual combination of front and back gap settings to make it work. Even so, the hourly output was still significantly lower than other types of creams due to the material property. Here, we want to introduce the scientific method our engineer utilized to maximize throughput, so that customers can make the most out of this award winning lab model ointment mill

Our engineer first observed the behavior of cream on the roller. The initial setting was 50 microns for both gaps. The cream was slow running into the feeding area and was stuck on the middle roller which meant bad transfer to the fast roller and the hence collection blade. The conclusion was that the gap between the slow and middle roller should be wider, while the gap between the middle and fast roller should be narrower. After a few rough adjustments, our engineer decided to fine-tune the gap settings with a series of experiments.   

He started from 150-micron back gap (gap between slow roller and middle roller), and 20 micron front gap (gap between middle roller and fast roller). First he needed to confirm for this particular kind ointment, higher speed lead to higher output. As it turned out in experiment 1to 3, higher speed did lead to higher speed, and the maximum speed didn’t cause the material to splash. He would use maximum speed for all the rest of the experiments.

Next step, he adjusted the front gap to 30 microns. The transfer from the middle roller to the fast roller got worse and the throughput was down. In experiment 5, he kept the front gap at 20 microns and used a narrower gap (100 microns) between the slow roller and middle roller. The throughput was down again, which meant the back gap needed to be wider. After a total of eight experiments, he settled at 250-micron back gap and 20-micron front gap. Our customer was able to reach their desired output as a result.
