Granulator, Chiller Blog

In a cabinet dryer, the feed is loaded onto trays that, depending on the required quantity of material to be processed and hence dryer size, are loaded onto trolleys or inserted into the drying chamber. The door is closed, sealing the system. The trays may have a solid or perforated bottom, depending on the feed particle size distribution. The carrier (typically, air) is drawn in through an inlet duct or recycle channel into the heating compartment. The air is heated to the required temperature in this region, then distributed from side-to-side (cross-flow) or bottom-to-top (through-the-bed flow) in a circular motion, according to specific drying requirements.
The motive force for the air movement typically is a plug-type fan that acts as both an induced draft and forced draft machine. The fan sucks the air through the heating chamber and blows it across the trays, which act as channels or ducts to direct the air. The fresh air inlet is located on the suction side and the exhaust is located on the pressure side. The inlet and typically exhaust will have dampers on them, enabling the percentage of recycled air to be controlled. This recycle improves the efficiency of the unit operation, conserving energy in the gas stream.

Cabinet dryers come in various sizes and may have multiple fans on larger units. Carninet Dryers also may be more than one heating compartment. Units can be electrically heated, have gas or LFO heat sources, or use indirect heat sources such as steam or thermal oil.

Cabinet dryers can dry all types of feeds from liquids and slurries to granules, agglomerates and solids (objects). Next month, I will look at dryer loading and unloading, residence time, ancillary systems and potential operating drawbacks.

Industrial chillers typically come as complete packaged closed-loop systems, including the industrial chiller unit, condenser, and pump station with recirculating pump, expansion valve, no-flow shutdown, internal cold water tank, and temperature control. The internal tank helps maintain cold water temperature and prevents temperature spikes from occurring. Closed loop industrial chillers recirculate a clean coolant or clean water with condition addititives at a constant temperature and pressure to increase the stability and reproducibility of water-cooled machines and instruments. The water flows from the industrial chiller to the application’s point of use and back.

If the water temperature differentials between inlet and outlet are high, then a large external water tank would be used to store the cold water. In this case the chilled water is not going directly from the industrial chiller to the application, but goes to the external water tank which acts as a sort of “temperature buffer.” The cold water tank is much larger than the internal water tank. The cold water goes from the external tank to the application and the return hot water from the application goes back to the external tank, not to the chiller.

The less common open loop industrial chillers control the temperature of a liquid in an open tank or sump by constantly recirculating it. The liquid is drawn from the tank, pumped through the chiller and back to the tank. An adjustable thermostat senses the makeup liquid temperature, cycling the industrial chiller to maintain a constant temperature in the tank.

One of the newer developments in industrial water chillers is the use of water cooling instead of air cooling. In this case the condenser does not cool the hot refrigerant with ambient air, but uses water cooled by a cooling tower. This development allows a reduction in energy requirements by more than 15% and also allows a significant reduction in the size of the chiller due to the small surface area of the water based condenser and the absence of fans. Additionally, the absence of fans allows for significantly reduced noise levels.

Most industrial chillers use refrigeration as the media for cooling, but some rely on simpler techniques such as air or water flowing over coils containing the coolant to regulate temperature. Water is the most commonly used coolant within process chillers, although coolant mixtures (mostly water with a coolant additive to enhance heat dissipation) are frequently employed.

A plastic granulator operates much like a large shredder. It turns full sized bottles, jugs, and other plastic products into flakes, or granules. The material produced by the plastic granulator is later sold to molders and manufacturers of plastic products as recycled raw material. The recycled raw material can be used to make new plastic items. Aside from aluminum and glass, plastic is the only material capable of being reprocessed into new items that are of the same quality as the original.

A plastic granulator is comprised of a large electric motor that turns a rotor. Cutting blades are attached to the rotor and encased within a closed chamber. These blades and chambers are available in numerous shapes and sizes. When used plastic material is placed inside the chamber, the rotating blades shred it into granules.
A screen is also located inside the chamber. It serves as a shifter, ensuring the plastic is small enough to be resold. If the plastic pieces are larger than .125 to .375 inches (0.318 to 0.953 centimeters), they are reprocessed until they are small enough.
A plastic granulator is rated by pounds per hour, which refers to how much it can shred within an hour. For industrial recyclers, the chamber of the plastic granulator needs to be large. It is, however, possible to purchase a plastic granulator for home or small business use. It is important to note that these machines can be a dangerous, no matter how small. Therefore, it is important to follow the precautions provided by the manufacturer.

Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. From 5,000 years ago, when beeswax formed the pattern, to today’s high-technology waxes, refractory materials and specialist alloys, the castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. Lost foam casting is a modern form of investment casting that eliminates certain steps in the process.

The process is generally used for small castings, but has produced complete aircraft door frames,
steel castings of up to 300 kg and aluminium castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.

What Is It?

A Foley catheter is a thin bendable tube with a balloon on the end. The end of the tube and the balloon are pushed into your bladder to drain urine. While this tube is in the bladder, urine is drained from it right away. You may need this catheter for just a little while or for a long time. How long you need it depends on why you have it.

The bladder is a hollow organ that holds urine. When you are ready to pass urine, it travels through the urethra (a small tube) to an opening in the body. Urine is let out of the body through this opening.
Why do you need it? You may need a catheter because of an infection, or a swollen prostate gland. You may need a catheter because of medicine you are taking. You may need a catheter because of a disease or an injury that is

causing problems in your urinary tract. Catheters may be used because you cannot pass the urine by yourself. After surgery, some people need to have catheters. The catheter is often used to keep track of how much urine a person is passing. When you have a catheter, it is important that you drink enough liquid every day. Ask your caregiver how much liquid you should drink each day.

Inserting a Foley catheter:

You will need to lie on your back covered by a sheet. While wearing sterile gloves, your caregiver will carefully clean the area around your urethra.

A soft tube called a Foley catheter will be gently put into your urethra. The tube will pass through the urethra and into your bladder.

When the tube gets to your bladder, the balloon will be filled with sterile water by your caregiver. The balloon will keep the catheter in your bladder.

The balloon presses against the wall of your bladder. This may make you feel like you need to pass urine. Instead of you passing the urine, it will drain out the catheter and into the urine bag.

To keep the catheter in place, it will be taped to your abdomen (stomach) or leg.Putting in your catheter should take about 10 minutes.

Caring for your Foley or leg drainage bag:

Catheters are designed to be closed drainage systems. This means that the path from the tip of the catheter inserted into the bladder, to the bag which catches urine, is closed. A closed system decreases the chance of getting an infection. It also decreases the chance of the catheter breaking and urine spilling out. People with catheters and their caregivers should avoid detaching parts of the catheter along the closed system unless it is necessary.

Larger, sterile, drainable, 2 liter drainage bags or smaller sterile leg bags are used to collect your urine. To
keep a closed system, these bags are connected directly to the catheter. If you use a leg bag to collect urine, a larger drainage bag may be attached at night with a special connector. A drainage bag should be emptied only when it is full enough that this is needed. Some plastic drainage bags should be changed every 5 to 7 days. Ask your caregiver how often your drainage bag should be changed.

Drainage bags must be kept below the level of the bladder. This will allow gravity to help drain the urine, and will stop urine from flowing back into your bladder. Urine that flows back into your bladder increases your risk of an infection. Do not let the drainage bag rest on or touch the floor. The tubing that goes from your urethra to a leg bag should be secured to your thigh with special tape, a leg strap, or a drain tube stabilizer. Allow extra tubing between the urethra and the point where it is secured to your thigh.
CARE AGREEMENT:

You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.

If you like to smoke tobacco and you are sick of the traditional forms of smoking, then you obviously have never smoked out of a tobacco water pipe. A tobacco water pipe has a reservoir that you place water into. The bowl, the object you place the tobacco into, is attached to a stem that is then submerged into the water.

As you light the bowl with the tobacco, you inhale through the hole that is designated for your mouth and the tobacco is then filtered by the water as it flows into your lungs. This makes smoking safer than using a regular tobacco pipe and the experience is much more enjoyable, according to the many people who regularly enjoy smoking from tobacco water pipes.

Hookahs
For centuries, people have smoked from tobacco water pipes but they called these hookahs. Middle Eastern countries such as Iran, Saudi Arabia and Turkey are well known to use hookahs. These tobacco water pipes have long, ornately carved stems from which many hoses emerge. The idea is that when the bowl is lit, several people can enjoy the smoke at once. This makes the hookah a truly unique smoking experience, something enjoyed by several at once rather than being just a solitary activity.

Most hookahs are lavishly decorated and it’s not unusual to see gold and even jewels used in the decorated of the tobacco water pipe. In some countries, it’s seen as odd not to own one and the popularity of hookahs has even encouraged the opening of hookah lounges. These establishments sport several hookahs where customers can come to sample different flavors of tobacco. Sort of like a bar, it’s a bonding experience where many people can come and relax and smoke off the hookah.It is important to clean your tobacco water pipe regularly. If you don’t clean your tobacco water pipe, you could affect the taste of the tobacco you use and it can also hinder your experience in other ways, such as making you sick. Change the water regularly and make sure you use a pipe cleaner on the hoses as well as the stem. Keeping your tobacco water pipe clean is seen as etiquette, especially if other people will be smoking off it.

Tobacco water pipes can be made from different materials. There are glass water pipes, plastic and even metal. The different materials can be cleaned but you must be careful of the cleaning agents you use to prevent damaging your tobacco water pipe. It’s best to just use warm water if you can get away with it as certain chemicals can damage your tobacco water pipe and that would be a shame, especially if you owned a beautiful, elaborate hookah.

Owning a tobacco water pipe is a special thing, as many people can become attached to theirs. Once they smoke from their tobacco water pipe, they would rather not smoke out of anything else. If you like smoking, and you like pipes, get a tobacco water pipe and you’ll likely never stray again.

Pump maker Disetronic announced on May 29 that its new Ultraflex Soft infusion set is now available for all insulin-pump users.

The Ultraflex Soft has a reversible connector at the base that “clicks” into place. In addition, it has a cannula that is tapered for easier insertion.

“We built this product from the ground up, using patient input to create the right features,” says John Odegard, marketing manager for Disetronic. “The Ultraflex is different from the Quick-set and Sof-set because the reversible ‘click’ connection system is much easier for persons who are vision impaired or have neuropathy.”

Odegard says the Ultraflex disconnects easily at the base, has a flexible Teflon cannula and doesn’t need an insertion device. It also has a clear window at the top of the infusion set, which makes it “easy to view your insertion site.” Compared with the Sof-set, Odegard says the Ultraflex introducer needle is a smaller 27-gauge.

“The Sof-set has a 26-gauge needle, which extends four mm beyond the cannula,” he says.

The Ultraflex Soft has a 90-degree insertion angle, as well as a soft Teflon cannula, which can flex with the patient’s body tissue.

The universal connection feature is compatible with all insulin pumps on the market. The set come sin two cannula lengths and three tubing lengths to fit all body sizes and types.

Odegard says all infusion sets need to be changed approximately every three days.

Oxygen mask: A mask that covers the mouth and nose, and is hooked up to an oxygen tank. It delivers oxygen directly to the patient. Oxygen can also be delivered directly through a nasal catheter, a tube that divides into two smaller tubes that go into the nostrils.

Oxygen is a colorless, odorless and tasteless gas that makes up about 20 percent of the air we breathe (and at least half the weight of the entire solid crust of the earth) and which combines with most of the other elements to form oxides. Oxygen is essential to human, animal and plant life.

The chemical symbol for the element oxygen is O. As a medicinal gas, oxygen contains not less than 99.0% by volume of O2.

Oxygen was discovered in 1774 by the British scientist Joseph Priestly but he did not name it “oxygen.” He called it dephlogisticated air. (Priestly discovered three other chemical compounds, one of which, nitrous oxide -”laughing gas” – is still used today as a mild anesthetic agent, as during dental procedures.)

The word “oxygen” came from the French “oxygene.” It was so named by the French scientist Antoine Lavoisier (1743-94) who thought it was a necessary ingredient in all acids. This is not so. Hydrochloric acid (HCl), for example, contains no oxygen.

With a wide range of capabilities, the new Thermoforming U Series offers versatility and accessibility. A castered base provides a low profile making the U Series ideal for under-the-press or in front of the press applications.

For easy clean out and maintenance, two swing open doors allow easy access to the screen cradles and screen, while two pivoting doors offer complete access into the bottom of the cutting chamber. The rotor and bed knives can be accessed from the 8″ pneumatic upper hopped by tilting open the upper chamber.

The U Series features a 3-blade open rotor with Twinshear cutting geometry, providing a quieter, cooler operation making it ideal for polypropylene.

With three model sizes available, the U Series offers a horsepower range of 20-50 HP and throughput capacities of 1800-3000 lbs/hr. A 12″ cutting circle, hi-angle rotors knives, reversible bed knives with D2 construction and NEMA 12 controls come standard. 5-blade open rotors are available options.

Engineering is the world leader in size reduction equipment, while also offering a complete line of downstream extrusion equipment.
