Vapor degreasers have been around for a long time, but that doesnt mean they are all created equal. Best Technology offers the highest quality vapor degreasing machines in industry. The significant advancements in cleaning solvent fluids have brought increased solvent costs; therefore, solvent recapture and vapor degreasing distillation have never been more important. Ensuring the proper boiling heat capacity balanced with chilling capacity and freeboard is a must for todays vapor degreasers. We are experienced in proper vapor degreaser equipment sizing and the latest chemistries used in them.
Inside the tank, liquid solvent is heated to a vapor which envelops the soiled part suspended in the vapor zone of the vapor degreaser. As the vaporized/boiled solvent condenses when the part at ambient temperature enters the vapor, dirt and contaminants are washed from the part and drained back into the liquid solvent solution in the boil sump of the vapor degreaser. Optionally, in some vapor cleaning machines, the parts may also be immersed into the solvent with ultrasonics in the rinse sump to microscrub the particulates off into the solvent.
If youve ever been wearing glasses as you walked into an air-conditioned building on a hot summer day, you already have a good understanding of part of the Vapor Degreaser process works. (For those in colder northern climates, walking outside while wearing glasses on a cold winter day is an even better example)
So, how does a vapor degreaser work? A vapor degreaser has two tanks (sumps) of solvent inside. One vapor degreasing tank boils the solvent (boil sump) whichcreates a vapor or mist of the solvent. The second sump (ultrasonic sump) is heated but not to the boiling point and is used as the second cleaning stage. The vapor degreaser also has bands of cooling coils inside just above the level of the sumps. These coils cause the vapor to return to a liquid state and fall back into the sump. The effect is like small clouds of the solvent are formed between the top of the sumps and the cooling tubes.
As parts at room temperature are lowered through the cooling area into the vapor, the vapor from the boil sump condenses on the parts just like moisture in the air does on your glasses in the examples above. This condensation contains the solvent that dissolves the oils on your parts, and the beading action creates droplets which run across the surfaces of the parts and fall back into the boil sump. The parts are then moved to theultrasonic sump which contains heated but non-boiling solvent. This allows the parts to be lowered into the sump so that any blind holes or internal features are also thoroughly exposed to the solvent.
Finally parts are raised into the cooling coil area to allow the solvent to quickly dry and and then raised through a second layer of freeboard coils near the very top of the vapor degreaser that insure complete drying and the recapture of the solvent from the parts.
Desiccants are used to absorb the water found in humid conditions to reduce or eliminate condensation. It can also be added directly to liquids to absorb the water content from the fluid. We are used to seeing the small white bags of desiccant found in packaging for everything from shoes to electronic equipment. Most of this desiccant is silica typically in gel form. Other common substances used as desiccants are activated charcoal and calcium chloride.
The desiccant used in vapor degreasers is 3 Angstrom Molecular Sieve, small pellets of zeolite clay. Like all desiccants, the zeolite clay adsorbs water from the solvent, and may be reused by baking it dry. Desiccants are most often used in a vapor degreaser if the solvent contains an alcohol. This is often the case with solvents used for defluxing processes on soldered boards and leads. Water found in the separator extracts the alcohol from the solvent and in turn the water and alcohol are absorbed by the zeolite clay. If a degreaser is operated in a very humid environment, a desiccant may be needed to effectively remove the water from the solvent.
Our vapor degreasers come in a variety of configurations depending on customer application. We can size a vapor degreaser to fit not only your parts, but also your cycle time and production requirements. With todays solvents it is essential to size the vapor degreaser properly to ensure maximum solvent recapture through distillation cycle chilling coils.
For one medical device manufacturer, the design of a citric passivation solution faced two major challenges: The manufacturing process required performing a water-break test after cleaning parts, before proceeding to passivation. This meant that they could not use a fully automated passivation solution. The system had to have data tracking for quality control purposes. Semi-Automated 
A rotary dryer or a drum dryer is a type of industrial dryer that is used to reduce the liquid moisture content present in the material within the device by bringing it in contact with a heated gas. It is typically made of a rotating cylindrical tube which is supported either by steel beams or concrete columns. The device is a slightly inclined, such that the end from where the discharge happens is lower than the material feed end, thus making it easier to make the material flow through the dryer under the influence of gravity. How does a drum dryer work? The material that needs to be fed into the device, enters the dryer and the dryer is then under rotation. Due to this, the series of internal fins which are lined up on the interior walls lift up the material in the dryer. Once the material is high enough, it rolls back off the fins and falls at the base of the dryer and as it falls, it passes through hot gas stream. This gas stream can be moving in one of the two ways: from the feeder and towards the discharge end which is called the co-current flow. Or from the discharge end to the feeder end, also known as the counter-current flow. A rotary drum dryer is best suited to dry metallic as well as for non-metallic materials such as clay in cement industry or coal slime n a coal mine. Applications Since drum dryers are simple to use, they find extensive use mineral industry to dry out sand, stones, soil, limestone, ores, coal, fertilizers, iron sulphate, sludge, sewage etc. They are also used in the food industry for liquid and granular substances such as cereals, food grains, coffee beans, pulses etc. Combined Processes Drum dryers can be combined with other processes such as cooling, cleaning, shredding and separating to increase their economy. Variations The drum dryer variations are many and depend on certain factors: Variations based on number of drums: You can find the single drum, the double drum and the twin drum Variations depending on the pressure surrounding the drum: You can find the atmospheric drum dryer and the vacuum drum dryer Variations depending on the feeding arrangement: There is the nip feed, the splash feed, the dip feed and the roller feed drums Based on the material of construction: The alloy steel, the stainless steel or the chrome or nickel-plated steel Drum Dryer Dryer Manufacturers Rotary Dryer Manufacturers Drum Dryer Manufacturers in India Rotary Drum Dryer Manufacturers Images
Weve built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECOs design team can design a rotary drum dryer for your application.
Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.
The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.
All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.
Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:
Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.
