hi,
any cons using ultrasonic humidifier?

This post has been edited by genkis3: Aug 12 2009, 08:17 PM

I love to try on Ultrasonic Humidifier because it really don't wet the floor that much like our faithful Taiwan Chicken Humidifiers .... but then does the ultra sound create Ultra sound/vibration disturbance to the swiftlets and also UH has its problem like replacement of the ceramic oscillation disc which may be broken after so long usage. If so, where to get the replacement . Never dare to try them and if anyone around here did tried, I believe many would like to know more about it and whether if it create any disturbances to the birds.

For Ultrasonic cleaning, I have tried it once a few years ago and you can't produce a finished half round nest with it. You can only break down the nest but then, by wetting the nest, and then cleaning with a good tweeter will be a better option. I did even tried using a suction pen to remove feathers but fail on that, too.

Maybe, I did the wrong way,maybe some readers may have got it right. Hope that you will or can share your experiences with us for the benefits of the industry. Share your experience and you gain more, that what I believe.

ultrasound humidifier??
i dared not to try yet.
we don't know what is the hearing frequency of swiftlet.
the ultrasound humidifier actual use is not for swiftlet farming. so the manufacturer just adjust the frequncy above human hearing range ( 20khz), human will not able to hear the sound.
but swiftlet so sensitive to sound, their hearing range must much higher that us, we not hear any sound, but doesnt meant swiftlet not hear the sound. Good example is dog, normally dog hear the soound b4 us.
swiftlet use echo to fly in the dark. so , think carefully, is the vibration will cause "stress" to swiftlet??
the ultrasound humidifier jt promote by those unresposible blogger. their aim is making money.
or their also not really understand about swiftlet, but become a con$ultant already.
think about the swiftlet hearing range.........
ths is only my 2 cent opinion.
correct me if im wrong

I'm having problem with humidity control in my BH... but in a reverse way. My BH is without any humidifier or mist sprayer. But yet the natural humidity of my BH is so high that the hygrometer always shows 'Hi' (Max) in the morning and the min reading ever recorded was 78%. Lately I've found mold (white spot) growing on the wooden plank that host the timer and the power points. I opened up all ventilation holes (177 of them) but the hygrometer still show 'Hi' or 80+% on average. So far, no white spots found on the nesting planks but I'm worry one day it will. Any comment ?

I wonder why your BH humidity so high? Do you have water pond inside your BH?

Let me get my immagination go wild......let see

1. Your BH must be either or a few of the following
a) a wet area like with underground water.
b) very near to water sources like river or others.
c) cannot be in town
d) Your internal temperature must be under 25C.

2. If above is the truth, then your BH must have a free flow of air from A to B and so the wind bring in the cold air into the BH.
3. If my 2th. predictions is correct, easily solve is to .........................

3. Solutions:
a)close all ventilation holes in your BH as you don't require any of the V holes as you have too much air flow and dampness.
b) Prevent the flow of cold air into you BH

Well, like I say, it is from my imagination............ and hope that I get them all right. C'mon, Sifus with experience in it may want to comment and advice us.

No. No water pond, no mist sprayer, no humidifier and not a single drop of water can be found in my BH. Even the humidity measurement taken outside of the BH (open air) can easily reach 80%+. ( tested by 2 different hygrometer).

WW, your guess is pretty accurate. My BH is located in rural area and near river. Ground floor temperature fluctuate around 25c to 27c.
I opened up all 177 VH because I thought stagnant air helps mold formation and let the damp air flow out. No ?

I copy & paste the following for you all to judge for yourself. Will prolong use cause 'White Dust" to form on the nesting planks and damage it forever? We need more data. FYI, Air-O-Swiss is a manufacturer of ultrasonic Humidifier. Looks like it needs super clean water & a lot of maintenance. Use it at your own risk.

"The Air-O-Swiss Room Humidifier System works by Ultrasonic Humidification. Water from the Removable Water Reservoir first travels through a Dimineralization Cartridge. The granules within the cartridge remove minerals from the water that can produce "white dust" in the room and also prevents lime scale build-up within the humidifier, making cleaning a simple task. White dust is caused when minerals are carried into the room air from a humidifier and precipitates out when the water vapor evaporates. After leaving the Dimineralization Cartridge, the water travels to the base of the unit where it contacts the patented Ionic Silver Stick®. The Ionic Silver Stick® releases silver ions to kill bacteria and viruses within the water and maintain constant water purity. If the pre-heating option was selected, the water will be heated to 176°F. The water within the base then travels to the Nebulizer Chamber and contacts the Ultrasonic Vibrator, which creates high frequency oscillations to transform the water in the base into a micro-fine mist. The Ultra-Quiet Fan pushes air into the Nebulizer Chamber where the air and micro-fine mist mix together. The air continues up the Evaporation Chamber and is released into the room where the water vapor fully evaporates immediately to release moisture and increase the relative humidity of the room


Maintenance

Water conditions will dictate the amount of maintenance and cleaning required. Using hard water with a lot of minerals will require more frequent demineralization cartridge changes and unit cleaning. The design and features of the Air-O-Swiss Humidifier provides a system that requires much less maintenance and has lower operating costs when compared to other humidifier systems.

Maintenance Procedures

*

Every two weeks check the unit base for any deposits. Clean any deposits around the titanium disc with the provided brush. Use a mixture of white vinegar and warm water in a 1:2 ratio to help remove deposits.
*

Replace the demineralization cartridge every 2-3 months, depending on water conditions. More frequent changes may be needed for hard water (high mineral content) conditions.
*

Replace the Ionic Silver Stick® once a year."

good
bad

Like I said, if you did a study of your area before you started your BH, you wouldn't have the problem. Instate of solving them, you are trying to add more dampness in to your BH and no bird of good sense will build their nests there as the eggs may not hatch and chick will die of cold.

Closes all VHoles and hope that the H is high but the temperature in the BH must be high for the eggs to hatch ( expert in chicken rearing here will tell you so) Don't you worry as we here have all type of professionals in all trade...... venturing into the BH industry for early retirement plan and I believe they are willing to share their expertise for the betterment of all.

Wind and cold are not good for the breeding of swiftlets. Brighness is not a safe place for swiftlets....we have have problem with low humidity and too warm as town sometime shoot up to even more than 36C.......until the parent bird even pull off their feathers even not in the season.....

Tha't my personal opinion only....

We ever came across a new standalone BH built on an opened agricultural land about 500 meters away from sea front somewhere in Johor. After having operated for only 2 months, moulds formed on many nesting planks and the internal condition was very damp and cold at most time esp during the night. The humidity level at all time averaged around 90 and above despite all chicken humidifiers were not used. No AF stayed. The best solution found was to close up all the ventilation holes to prevent further moist breeze from the sea to come into the BH. The condition improved. Today, after 2.5 years in operation, the number of nests reached 500 pieces.

Hope our experiences and findings could be of help to some of our forum friends who are facing the same problem.

When I googled the web for more DATA, I found this, Ultrasonic Humidifiers May Be a Health Hazard

http://findarticles.com/p/articles/mi_m087...n50/ai_7650971/

and I hope it's not the same for the birds beside removing bacteria in the BH. The water used to generate the mist should not be directly from the tap water. On hearing frequency, I gather some ultrasonic sound does not interest these birds at certain level.

Ultrasonic cleaner will be the in thing if labor can be cut to the minimal. They claim that the number of cup-shaped nest can be done in the minimal time. I haven't seen the cleaning done so far so I can't share with you here the statistics of it. Instead of suction pen used for removal of feathers, smallest drill bit is used to that end.

WW. if I understand correctly from aeiou228, before the VH were opened, the humidity was high and caused mold on plank. After he opened the VH, no more mold but humidity still high. So, if you advice him to close back the VH, then the BH condition will back to the old one. right?

I have 2 friends have high humidity issue also. What they did is to use ventilator or fan to blow the air out through the bird entrance hole. It help to reduce the humidity. But please make sure the speed of air is low and blow to the floor. Hope it help.

Thank you all for your suggestions and views.
As the matter of fact, no mold was found on the nesting plank, probably due to the nesting planks were all kiln dried planks. Mold was found only at the wooded board that house the timer located in the ground floor control room.
I will try to trouble shoot again by closing and opening the VH and see the outcome.

BTW, my BH is a stand alone 20' x 70' x 3 storey building. Top floor temp max at 30.2C and ground floor temp about 2 to 3 degree colder.

good news coming,,,later haiwan will handle bird nest exporting n perh*****n will be out of biz,,,

Wah!!...Bro, so free ahh? hehe...

ai yo yo!!....agriculture kah??

can breed swiftlets liked chicken kah??

really kah??

I thought the son of our Former PM should be more clever liked his father mah!!!


ai yo yo!!....really can meh?? how come this TECHNOLOGY already existed in Indonesia for Over a decade but till now u see no

FARM IN INDONESIA ADOPTED THIS METHOD??

why indonesian so soh hai still build farm n wait for birds to come??

guess they are no soh hai but Malaysians are the big soh hai !!...not all lah...only a few oli mah!!


sai hei!..

aeiu228 posted that he open all the Vholes but didn't mentioned that he didn't open any before the incident happened. As I see it and from what I learn ( although not much), dew will only form on open water and soil which must be wet only then the cold air make the water particles from the water surface and the land to form dew and the wind blow them into the BH. The bird house interior is not wet and will be warm and since the air inside is stagnant and will remain for quite sometime and even so, will only slowly become cooler but then, it will be warm again when the sun rise. So, with my little knowledge and understanding but wish to know more, I think that by closing all V holes will prevent and slower the cold air outside from entering the BH and that's why I said prevent the wind from blowing into the BH.

The same reason why if Malaysian is caught off guard in case it snow in Malaysia, we shall all shut all air gaps and windows to prevent cold air from entering and warn air from leaving and worst if the wind blow into our house. Do I get it right?????

Above comments are to seek the truth so that others may learn but with no ill intention or argument for argument sake. Knowledgeable guys may like to give advices to us.

I should have given more info in the first place.
My BH is a stand alone 3 storey building and have 177 4" VH. Only 10% were closed prior to opening all. Now I shall do an experiment to close all VH floor by floor and monitor the reading of hygrometer.

I have this logic in mind but not sure whether it is correct or not. Damper and cooler air is heavier, therefore the ground floor should have more air pressure then the upper floors, thus open up VH in ground floor will allow damp air to flow out ?

Rearing swiftlets as agriculture: Mukhriz

2009/08/15

KULIM, Sat: Rearing of swiftlets should be made one of the industries in the country's agriculture sector because of its lucrative income, Deputy International Trade and Industry Minister Datuk Mukriz Mahathir said today.

He said the technology in the rearing of swiftlets had changed and that the bird could be bred using the hatchery process and then reared for its nests.

Speaking to reporters after opening an association for agriculture and agro-based industry entrepreneurs and a swiftlet rearing project here, he said such a project was being carried out by the association at Kampung Sungai Tengas, near here.

Some 8,000 birds were being reared in the project and when fully operational was expected to yield an income of RM120,000 a month, he added. -- BERNAM

I thought hot air has more energy and therefore more pressure. I agreed what WW said. Try to close all the VH first. After all your BH is new BH, close all VH can help to keep the aroma smell in your BH.

You are right too. now NVM, just do the test and see the result later.
