What is dry ice maker?
Dry ice maker
is a machine that makes dry ice.
What is dry ice?
is a solid carbon dioxide, which is liquefied into a colorless liquid at a pressure of 6250.5498kPa and then rapidly solidified at low temperature to obtain. Nowadays, dry ice is widely used in many fields.
The history of dry ice
can be traced back to Faraday and Debye in England, who first liquefied carbon dioxide in 1823, followed by Chirri in Germany, who successfully produced solid carbon dioxide in 1834. However, the use of dry ice was limited to research and was not commonly used at that time.
Carbon dioxide is invisible, in fact, it is not (carbon dioxide) smoke, is (water) fog, carbon dioxide from a solid into a gas when absorbing a lot of heat, so that the temperature of the surrounding air drops quickly, the air temperature drops, its solubility to water vapor becomes smaller, water vapor liquefaction phenomenon, the release of heat, it becomes small liquid droplets, that is, fog. This and the summer popsicle bubble "white fog" is a meaning, are small droplets of water, rather than other substances in the gaseous state. So, what we see is white fog instead of white smoke.
Dry ice is much cooler than water, so it is equivalent to heating dry ice, which absorbs heat and sublimates, lowering the temperature of the water and even freezing it.
Application of dry ice
A. Mold industry cleaning
Tire molds, rubber molds, polyurethane molds, polyethylene molds, PET molds, foam molds, injection molds, alloy die-casting molds, hot core boxes and cold core boxes for casting, which can remove residual resin, failed release layer, carbonized film agent, oil stains, open exhaust holes, and the molds are shiny as new after cleaning.
Dry ice cleaning does not need cooling down and disassembling the mold, avoiding the chemical cleaning method to the mold corrosion and damage, mechanical cleaning method to the mold mechanical damage and scratches, and repeated loading and unloading lead to mold accuracy decline and other disadvantages. The key is that it can eliminate the two most time-consuming steps of disassembling the mold and waiting for the mold to cool down, which can reduce the downtime by about 80%-95%.
The benefits of dry ice cleaning: dry ice cleaning can reduce downtime; reduce equipment damage; extremely effective cleaning of high-temperature equipment; reduce or lower the use of solvents; improve staff safety; improve maintenance efficiency; reduce production downtime, reduce costs and improve production efficiency.
B. Petrochemical power
Cleaning of the main fan, air compressor, smoke machine, steam turbine, blower, and other equipment, and removal of coking and carbonization of various heating furnaces and reactors. It cleans polyvinyl chloride resin on heat exchangers, removes oil, rust, hydrocarbons, and surface dirt on various pressure vessels such as compressors, storage tanks, and boilers, cleans reactors and condensers, decontaminates complex bodies, and clears ash from furnace tubes. Can clean power boilers, condensers, and all kinds of heat exchangers; can directly clean indoor and outdoor transformers, insulators, distribution cabinets, and wires and cables with electric load (below 37KV); generators, motors, rotors, stators, and other components without damage cleaning; turbines, turbines on the impeller, blades and other parts of rust and dirt, hydrocarbons and adhesive powder cleaning, without removing the paddles, save the re-adjustment of the paddles Dynamic balance.
The benefits of dry ice cleaning include effective decomposition of cleaned contaminants; reduced power loss due to the removal of these contaminants; reduced maintenance costs for external equipment and its infrastructure; increased reliability of the power system; non-abrasive cleaning to maintain the integrity of the insulator; more suitable for preventive maintenance.
C. Food and pharmaceutical industry
Dry ice successfully removes baking residue, gunk, and grease from ovens and raw product mixtures before baking. Effectively cleans ovens, mixing and blending equipment, conveyor belts, molded products, packaging equipment, oven racks, pans, containers, rollers, freezer liners, cookie bars, and other equipment.
The benefits of dry ice cleaning include excluding the use of harmful chemicals, avoiding exposure of production equipment to harmful chemicals and generating a second waste; mimicking or removing bacteria such as Salmonella and Listeria for more thorough disinfection and cleanliness; excluding damage to electronic equipment from waterjet cleaning; minimal equipment decomposition; and reduced downtime.
D. Printing industry
Removing ink can be difficult, and ink buildup on gears and guides can lead to poor print quality. Dry ice cleaning removes a variety of oil-based and water-based inks and varnishes, cleans oil, ink buildup, and dyes from gears, guides, and nozzles, and avoids the release of hazardous waste and solutions, as well as injuries to personnel caused by hazardous solvents.
E. Automotive and marine industry
Cleaning door skin, canopy, carriage, underbody oil, and other non-water stains, will not cause water pollution; car carburetor cleaning and car surface paint removal, etc.; remove engine carbon. If dealing with carbon deposits, it takes a long time to deal with chemicals, at least 48 hours or more, and the chemicals are harmful to the human body. Dry ice cleaning can completely solve the carbon problem within 10 minutes, which saves time and reduces costs, and the descaling rate reaches 100%. Ship hull; seawater inlet valve; seawater condenser and heat exchanger; machine room, machinery, and electrical equipment, etc., cleaner than the general cleaning with high-pressure water jets.
F. Electronic and nuclear industry
Cleaning robots, automation equipment internal grease, dirt; integrated circuit board, solder after welding flux, pollution coating, resin, solvent-based coating, protective layer, and printed circuit board on the photosensitive anti-corrosion agent removal.
G. Aerospace field
Missile and aircraft painting and pre-assembly processes; paint removal from composite molds and special aircraft; engine carbon cleaning; maintenance cleaning (especially landing gear - wheelhouse area); aircraft shell paint removal; jet engine conversion systems. It can work directly on the airframe and save time.
Nuclear industry equipment cleaning if the use of water, sandblasting or chemical purification agent and other traditional cleaning methods, water, sandblasting, or chemical purification agent and other media are also contaminated by radioactive elements, the treatment of secondary contamination of these media need time and money. The use of a dry ice cleaning process, dry ice particles are directly blasted to the object to be cleaned, with instant sublimation, there is no problem of secondary contamination, and the need to deal only with the wastes washed away with nuclear contamination of the scale, and so on.
H. Food Industry
a. Adding dry ice cubes to wine, cocktails, or drinks, it is very pleasant to drink with cool and delicious smoke in the glass.
b. Adding dry ice to ice cream making makes the ice cream less likely to melt. Dry ice is especially suitable for the refrigeration and transportation of takeaway ice cream.
c. Star hotels and restaurants produce seafood specialties, and adding dry ice to the table can produce a white smoke landscape to improve the banquet grade, such as the production of lobster sashimi.
d. Lobster, crab, shark fins, and other seafood are frozen and refrigerated. Dry ice does not melt water and is cleaner than water ice refrigeration, so it is widely used in Europe, America, and Japan.
I. Refrigeration and transportation field
a. Low-temperature frozen medical use and low-temperature transportation of special drugs such as plasma and vaccines
b. Electronic low-temperature materials, long and short-distance transportation of precision components.
c. Fresh transportation of high-grade food, such as high-grade beef and mutton.
J. Entertainment field
It is widely used in stage, theater, film, and television, wedding, celebration, party, etc. to produce the effect of the sea of clouds, and there are countless classic plays in the country and the world that use dry ice to produce special effects.
K. Fire-fighting field
Dry ice is used for fire-fighting, such as some low-temperature fire extinguishers, but the application of dry ice in this piece is less, i.e., the degree of the market is low.
Type of dry ice maker
There are three types of dry ice machines commonly available in the market today: water bath, screw, and centrifugal. Auxiliary raw materials such as refrigerant and desiccant are used in the manufacturing process, so the price of a machine is also determined by the price of these raw materials.
The manufacturing cost of a water bath dry ice machine is low and easy to operate, but its refrigeration capacity is small; while the manufacturing cost of a screw dry ice maker is higher but the refrigeration capacity is large and easy to operate some, so generally, large factories use this equipment to make. The main difference between the two is the difference in the refrigeration system.
The advantages of the spiral dry ice machine are small, lightweight, and low noise; the disadvantage is that the structure is complex and expensive, resulting in its high cost. The disadvantage of a centrifugal dry ice maker is its small size, lightweight, and low noise; the disadvantage is its high cost due to its complicated structure and relatively high price.
