Ultrasonic Humidifier

How it works
  • Ultrasonic humidifier has a high frequency oscillator. The output is fed to “Piezo-electric transducers”.
  • The “Piezo-electric transducer “creates a high frequency oscillations in the water.
  • The water cannot follow the high frequency oscillations, thus a vacuum is created on the negative oscillation, causing the water to cavitate into vapor.
  • A positive oscillation creates compression waves on the water's surface, releasing vapor molecules of water into the air.
  • Fine mist is created by oscillations, thus the water temperature remains the same.
  • Ultrasonic humidifiers create instantaneous humidity, and don't have to wait for a heating element to boil the water.
  • The precise on/off humidity control is the hallmark of ultrasonic humidifiers.

Applications of Industrial Ultrasonic Humidifier :
HUMIDIFICATION IN COLD ROOMS and potato cold stores :  

Potato production in India has shown a steady increase in the last 50 years. Increase in production often resulting in gluts at harvest, has led to several post-harvest problems and the major one is that of storage. A total of 90 per cent of potato crop of the country is harvested during January-February from the Indo-Gangetic plains, comprising the states of Punjab, Haryana, UP, Bihar, West Bengal, MP and Gujarat where the harvest is followed by rising temperatures of hot and dry summer and further by warm and humid rainy season. Since potato tubers contain about 80% water, under these conditions potato, a semi-perishable commodity can not be stored without refrigeration for more than 3-4 months due to very high losses as a result of shrinkage, sprouting and attack by microorganisms.

Therefore, potatoes are mostly stored in refrigerated cold stores maintained at 2-4oC and 90-95% relative humidity (RH). Low temperature storage has advantages of natural control of sprout growth, low evaporative loss, minimum risk of diseases and pests and reduction of senescent sweetening. These conditions are ideal for storage of seed but it causes cold-induced sweetening leading to excessive accumulation of sugars in most of the potato cultivars making potatoes unfit for processing due to browning in chips and these are less preferred for consumption because of sweet taste. Hence, potatoes meant for processing are either stored under non-refrigerated conditions for short term or stored at 10-12oC with the use of CIPC (isopropyl N-(3-chlorophenyl) carbamate), where the accumulation of reducing sugars is minimum and chips produced are light in colour.

Reasons of Potato Weight Loss: 
As we can easily see that air conditioning is working as a de-humidifier because moisture is sucked from inside and water falling out of the unit. In the same way Chilling units in the cold storage are working as a dehumidifier and a large volume of moisture is sucked from the chamber. Every year potato losses 10% of its weight due to low humidity which can be easily prevented by maintaining proper humidity levels in the cold rooms. We are in the field of providing humidity solutions for any kind of storage unit.
Different temperatures have different water holding capacities. Therefore capacity of humidifier is more or less dependent on the temperature irrespective of the volume of that area.

Advantages of humidifier in potato cold storage:

  • Maintaining humidity at proper levels helps in preventing weight loss.
  • Helps in maintaining the freshness of the product.
  • The size of mist particle is so minute that it doesn’t condense and saves potato from rottening due to water.
  • Less weight loss helps in building the goodwill of the cold store.

Humidification in Baking Industry :  

Another major role of humidifier is in the field of baking industry. During fermentation process proper humidity is required for baking. Humidity and temperature are the two major essentials required for proper baking.
In bread manufacturing units humidifiers can be used as a substitute for boilers in the final proover. Our humidifiers are very much economic as compared to boilers because boilers needs a cost for its running whereas humidifiers are very much economic as compared to boilers. The only recurring cost is of water and small amount of electricity.

Humidification in Ripening Chambers :  

Banana/Mango etc ripening chambers Proper humidity levels are the basic requirement of post harvest ripening of fruits along with the temperature. An ideal humidity of 85%-95%  is required for proper ripening of the banana.

Humidification in Tea & Tobacco Industries :  

Humidifying Tea During The Fermentation Process Allows Oxidization To Fully Occur As The High Humidity Prevents The Tea From Losing Moisture To The Air. If The Tea Dries Then The Fermentation Process Is Impaired As Oxidization Only Occurs In The Presence Of Moisture. By Maintaining A More Consistent Humidity In The Rolling, Cutting And Fermentation Areas The Liquor Of The Tea Is Greatly Improved And The Amount Of Low Quality Refuse Tea Is Reduced By Up To 50%, When Compared To Standard Spinning Disc Humidification Systems. Tobacco leaves and paper are all extremely hygroscopic which means that they give up their moisture to the surrounding environment if the air is too dry. Dry air causes tobacco's properties to degrade resulting in shrinkage, weight loss, and brittleness, flaking, splitting and tearing. This causes tobacco to literally fall out of cigarettes, cigarette papers to misfeed on machines and cigar leaves to crack. Maintaining the right level of ambient relative humidity prevents all these problems by ensuring that tobacco, paper and leaves retain moisture at the correct levels, so maintaining their quality and ensuring that production can proceed at full efficiency.

Primary Production :  

Tobacco leaves most primary production areas with a moisture content of 13-16% by weight. An ambient relative humidity of 60-68%rH is needed to maintain equilibrium between the air and the moisture in the tobacco. If it is lower than 60%rH tobacco will be losing moisture, weight and quality.

Cut Tobacco Storage :

After the initial production processes, moistened tobacco is normally taken to large bins or silos. Smaller tobacco plants will rely on box or cut tobacco stores. These areas must be maintained at 60-70%rH and 21-240 C as they have large amounts of tobacco exposed to ambient air.

Buffers & Temporary Storage :  

The maintenance of around 60-70%rH is critical in and around temporary storage systems. cigarettes stored in a buffer for several hours or over a weekend will lose moisture if the relative humidity is not maintained, and are often scrapped due to drying out. Humidification means stored cigarettes can continue to be processed and wastage eliminated. Recovery & ripping areas Any loss in moisture will lead to poor recovery of tobacco in ripping rooms where production waste is broken up and re-used. These areas need to be maintained at 65%rH at 210C.

Electrostatic Build-Up :

If humidity falls below 50%rH then electrostatic charges can occur in most production areas even in filter rod areas where extra humidity is not normally called for. If conditions are maintained above 50%rH, then this will totally eliminate electrostatic charges.

Papers :

Cigarette paper must also be kept in equilibrium with the environment. If its moisture changes so will the dimension of the reel of paper along the exposed edges. These are then in tension as the paper runs, which can lead to tears, machine misfeeds and expensive downtime re-feeding the roll.

Correct Humidity Control Will :  

Maintain the quality of the stored leaves prevent product weight loss avoid dimensional changes of cigarette papers eliminate static electricity improve recovery in ripping rooms allow cigarettes to remain on conveyors during downtime.

Automotive Manufacturing Humidification :  
    Car Manufacturing Humidity Issues,
    Paint Spray Booths.
  • The optimum humidity for the transfer of paint from the spray gun to car body work is 72%RH. This prevents any evaporation of the water-based paint and allows the paint to reach the bodywork as the manufacturer intended.
  • By humidifying correctly paint costs are reduced by avoiding evaporation.
  • A major automobile manufacturer has increased the number of cars passed first time from the paint spray booths, without any sanding required, by 8% due to improving their humidity control.
  • As paint spray booths are fed air from a central air conditioning system the type of humidifier used is an in-duct unit. Historically this has been a spray washer system but a more modern solution is an evaporative humidifier, as the running costs are much lower and it provides totally hygienic humidification.
Sand Decks :  
  • The optimum humidity to eliminate static in sand decks is 55%RH. At this level the moisture content of the air changes the electrical charge of the dust so that it is the same as the surface of the car. This results in the dust running off the bodywork of the car instead of being attracted to it. This greatly decreases the sanding time and improves the quality of the finish.
  • By using a direct-air spray humidifier up to 4°C of evaporative cooling can be achieved around the sand decks. This is a very beneficial side-effect as these areas can reach up to 40°C under the hot inspection lights and with painted surfaces that have recently been through an oven.

Engine Test :  
  • To design cars that are suitable for global use, in a range of humidities and temperatures, the engine must be able to operate in such conditions. Humidifiers that can recreate any such conditions are an essential element of the air conditioning plant feeding these areas.
  • As close control of humidity is required the most popular form of humidifier for this application is a steam generating system. Although in some circumstances, a spray system can be used, giving considerable savings in running costs.
  • Formula One engines are precisely tuned to the humidity of the country they will be racing in using very close control humidifiers. Typically these will be steam systems run on reverse osmosis water.
Textile humidification :  

If your production facility is suffering from static build-up, low regain, yarn breakage, dust, fly or lint then you need a humidifier. These are all symptoms of dry air and can be combated by putting the moisture back into the atmosphere.
We have over 20 years experience in helping the textile industry across the globe solve dry air problems. As specialists in humidification, we offer a wide selection of low energy and close control humidifiers for all textile applications.

  • Dry air causes lower regain and this contributes to poor quality and lower productivity. Yarns with low moisture content are weaker, thinner, more brittle, less.
  • elastic, create more friction and are more prone to static electrification.
  • Materials at optimum regain are less prone to breakage, heating and friction effects, they handle better, have fewer imperfections, are more uniform and feel better.
  • Higher humidity reduces static problems. Reduced static makes materials more manageable and increases machine speeds.
  • Textile weights are standardized at 60%rH and 20°C. Low humidity causes lower material weight and lowered profits.
  • Low humidity causes fabric shrinkage. Maintained humidity permits greater reliability in cutting and fitting during garment creation and contributes to the maintenance of specification where dimensions are important, such as in the carpet industry.
  • Humidification reduces fly and micro-dust, giving a healthier and more comfortable working environment.
  • Spray humidifiers have a substantial cooling effect, reducing high factory temperatures.

Humidification in Mushroom & Orchid Cultivation :  

Mushrooms love dark and humid environments. To cultivate mushrooms humidifiers are used to maintain an optimum air humidity of 95%rH. The JetSpray humidifier is ideal for mushroom growing as it is a low energy humidifier with low running costs and the moisture released is totally evaporated into the atmosphere. If any droplets were to precipitate out of the air and fall on to the mushrooms it would cause brown spots to form on the fungus making them less attractive to consumers. Smaller agricultural facilities with up to 1,000m3 would suit the Mistifier Plus wall-mounted spray humidifier. It can provide up to 6.5 l/hr of moisture and is easy to install and operate.
