Water Pump

a large industry here in the us, too about all you are dpoing ! Great!

perhaps call in to CHICKMASTER of Medina Ohio, USA, and see if they will also yield a helpful comment for you .

I watched them grow since 1980, when they were questioning heat recovery from controlled temperatures and humidity, economizing all the processes from egg to final bird.

They were interested in using a compressor and refrigerant for both a heat source and absorbing heat energy from another area/process for cooling with just one refg compressor to do both of those things at one time. Heat-reclaim, heat-recovery.

(like with a water-to-water 'chiller' or reverse-cycling, and multiple heat-exchanger chiller, that has two or more condensing (hot side) refrigerant heat exchangers, for multiple applications.)

A nice idea! They are praise worthy.

you do not need to apologize or explain anything! ignore the ignorant and their bigotry. there are plenty of rational people here that will more than enjoy tossing your question back and forth seeking potential solutions.......and I'm squarely with Del on this one.

WOW, you stepped into that one.

Next time, take a look at the history of the poster.

If you had, you would have seen that this particular doctor has been here before.

Wow! Some cat sense here is fair enough ! thank you for clawing away the tares and weeds, D! now 'economically' may we return to the op?

Ahhh! -about when I find where the money maybe comes from that can just be for some reasonable profit -to me- then my being more cognizant of helpful judgement in an instance or two, I have to reserve commentary to first share what is 'on-the-table' a like, -.

What we may profit from (economics or self and/or global-interests) or be about just helping another out? ---Then I will more so lead/control thoughts less judgementally so reasoning fulfills a Prerequisite to first share other's thoughts in this multi-religio-nationalism human-secularism globally of all around. No one I know, completely thinking through any subject intellectually, and with some accuracy, is ignoring the tremendous make up of combined religio- and secular concerns of others in any venue. But first what just is the OP Q' ?

[ op-er, do you have an idea about 6 l of water rate need be? In a first minute? or a first 3 minutes?

2) How "atomised" is really needed? - like a common spray bottle we can hand squeeze/ or really a very fine misting from say 40 psi (kg?) which may be sufficient?

(I also only see evidence that there is but one global-georacial human race, as designed, too, so voicing some "suspicious"-ness early on/ -well, seems too early on here about any presumed context, so let's just ask more questions first, -questions alone, firstly.)

It should be 6 Liters in 6 minutes. The jet or spray should not be as such that the ingredients become something like dough inside the mixer machine. They should remain powdery. Please tell me how many nozzles are to be fitted? Should it come from a single motor or each nozzle should have a individual motor?

@Del the cat, Actually I have no idea about a water pump.

A very fine jet would possibly do.

It would run for 6 minutes, then rest for an hour & again for 6 minutes & so on. 8 hours a day.

I have tried to make the process clear in reply to#1.

SimplesT solution... If you have a mains water supply, or a supply with consistent pressure, you could probably make do with a very simple timer and solenoid valve to just open the water supply pipe for a short time. Of course you'd need a restrictor, regulator or valve on the line so you could choke it down to a suitable delivery rate, and a fine nozzle to give a fie jet or spray.
All those bits are easilly available and relatively cheap.

Del

Thanks for your suggestion. But my question was, what should be the specification of the pump & nozzle size, number of nozzles, so that I can make a shopkeeper understand.

Do you think that supply line from a 15 feet high reservoir tank would produce enough pressure to make very fine spray? Then a motorized pump won't be necessary which may reduce the cost.

gravity feed wont come close to the pressures you'll need! you must pump it it to get atomization you're looking for.

Yeah, I understand. Thanks a lot. By this time I have googled dosing pumps as per 'Del the cat' & have learned a lot. Huge sites are there.

id start here..http://www.aeromist.com/mist-nozzles.html

Ah, but I don't think atomisation is necessary!

I'd guess a 1mm nozzle would do the trick, and give a nice fine jet.
Del

I disagree. A jet will wet some particles more than others, and prevent even distribution.

Atomization is your best way to transfer the liquid to the powdered materials. Atomization creates the smallest water droplet possible at a reasonable cost. The flow rate of the water on the powder also effects the absorption rate. The many more atomized smaller droplets will spread more evenly than that from a regular spray nozzle.

Contact- Spraying Systems, Wheaton, IL, USA www.spray.com and ask for their help. The sales office local to you is in

They are the best to contact instead of CR4. We are a mixed bunch of engineers or interested personnel with a variety of interest and a wide variety of knowledge levels, not spray system engineers. I have used them in the past (more than a few years ago) for the application of oils onto powered casein, mixing in a ribbon blender. With my knowledge of the process and their knowledge of spraying we came out with an excellent economical way to get the oil on the powder. It was well dispersed, without local variations in the oil and done quicker than ever before.

Good Luck, Old Salt

If you have a person available, with 6 minute increments of time on their hands, one of these should work just fine. It would just be a matter of adjusting the flow rate and atomization to your needs.

Dear Kramarat,

This is possibly the cheapest solution of this problem. This solution should had to be in my brain, because we had used it in bird flu campaign. It produces good pressure. However, you deserve the credit. Thanks.

I would only add the idea that if you go with an air pressure driven gravity drop arrangement you could pre-measure the amount of water to be added then just let it run dry unsupervised. If the pressurizing air volume is at least twice the volume of water volume you should get a consistent spray the entire time until all water has been dispensed.

Quote from the doctor, #9

"The jet or spray should not be as such that the ingredients become something like dough inside the mixer machine. They should remain powdery."

C'mon... you can't expect me to read the whole OP
I jus' a cat

Short attention span?

I think a diaphragm or peristaltic pump as previously suggested will work with some sort of small air compressor or nozzle to atomize the water. The fact that the water storage tank is above the point of use is to you advantage and will mean that the pump used will be in a flooded position. The pump will always be ready primed for use. You may want to contact a manufacturer like Pulsatronic or LMI for specifications. They may also be able to suggest a nozzle that would be suitable at the point of discharge and bypass the need for an air compressor. I am not the expert to contact but I like what you are attempting to do with local farmers. If this is the type of pump you need PM me and I may be able to assist.

Use a 1 bag cement mixer for the mixer. Can be either electric motor driven or small gasoline engine. These are often used for more than cement. Mixing fertilizer, cattle feed, chicken feed and various other powders. Once saw one used for the mixing of silver containing dental amalgam used for teeth fillings.

Put a post in front of it to hold the spray nozzle(s) at the appropriate position. Use a lawn pressured spray can to hold the water and pump the handle for pressure. If the supply of city water is high enough directly feed the spray nozzles from the city water supply. Alternate is to use one of those pressurized containers that soda (pop) flavors come in prior to carbonization and mixing with water. Pressurize it with compressed air or one of those 12 volt "car" air compressors. Use an air regulator and a safety valve, these compressors don't have any.

When all this is done, let the combination mix until evenly dispersed. To empty the mixer flip the drum over to the discharge position and collect in a container shaped in the most convenient configuration for the use or packaging.

Good Luck, Old Salt

Increasing moisture level from that low(3%) to 9% will need very good mixing process. Any water spray without proper atomizing would result in nonuniform moisture in the mix.

Steam would be more reliable since the steam would "spread" more uniformly than water particles. You need to have very good atomizer and good movement of material across the sprayed water. Gravity fed water from about 15ft will not be sufficient. You will need to use pump and atomizer combination.

The atomizing spray nozzle manufacturer can guide about the specifics of design in better way.

Dr Syed: Blessings to you for caring for the poor. Someone has to. The way I had seen this done at the Texas Tech Ag experiment farm feedyard (beef cows), the used a low pressure steam boiler of small size. Owing to the tropical climate in Bangladesh, perhaps you could also utilize steam of a quite low pressure from low quality heat of (1) solar water heaters such as a salt gradient solar pond, (2) heat collection from metal roof, or (3) biomass combustion including crop, or wood waste. Spray the hot water down with a side stream of air directed through the mixer at a slow velocity, or alternatively use a compressed air stream to draw moisture (steam) out of the hot water sufficient for maintaining a high humidity level in the mixer. This will be enough to raise moisture content during mixing, and will not ball up the mixer. Good luck.
