Unless you dry the seaweed at some point in the process, the best you can hope for is mush and not dust.

He's buying his feed stock dried, pressed and cubed from LynDoor™Industries, DeepSeaDoodle Division.

Unless this is for a commercial application the household food processor will do. Use mine to powered Rosemary to use as a natural flea powered on the pets. make them smell nice too if you like Rosemary. Only problem is the white cat looks a little green afterwards.

A coffee grinder should work pretty well.

This is a very incomplete question. How do you expect someone to properly (and safely) help you ?

1. Are you looking for a manufacturing option or a home supply ?

2. Are you using this product as a poultice, a mulch, or as a food stuff ?

As asked, you crush dry seaweed with the bottom of your boot, by spinning the tires of your truck over it, or by running it through the prop of an airborne airplane. All of these methods will work to a varying degree depending on the size of the "dust" you wish to create.

No need to get fancy, a good old mortar and pestle will work fine...unless you want to go into production on a larger scale, then you may need something a little bigger...

I use a rolling pin, Boss.

There are many animals that eat and therefore crushes seaweed. I find it very strange that somebody thinks that they require the aid of an engineering blog to do such a simple act.

Some seaweed species are used in Southeast Asian cooking, including Chinese and Iapanese. Hence a competent cook can show you the basics. A TV presentation from the Fukushima area did show the local cottage industry harvesting and processing of seaweed species. I saw no machinery there.

Now, if you are interested in the mineral content, higher heat may be acceptable. If it should be used in the kitchen, or for its biochemical properties, much more gentle methods should be used.

I still am puzzled, why the powdering?!?

Brilliant response.

Spoken like a true salesman person, with a total lack of technical practical product knowledge.

Now, now, now. You should calm your frayed nerves here. The microscopic depth of initial information from the OP combined with the vacuous reply to any and all questions asked of the OP tells me that the OP deserves a salesman and not an engineer to "service" them.

I know, I know. There's no reason to fret.

I'm having fun watching a dozen small frys swimming.

No seaweed here.

Happy Father's Day!

Thanks, you too, if appropriate. It's 108°F here right now.

There's nowhere else to be but in the pool. It gets mega-use what with kids, neighbor kids, grand kids and the occasional duck visitors.

The dogs are gone, they used to swim, too.

The answer provided by Kodichina is a spot on, technically sound, generic description for what needs to happen. It's up to the OP to scale this process as required.

I gave Kodichina a GA for his/her pure response.

The self serving response does in no way qualify as an appropriate response to the OP's question, "I would like to know what kind of machine should I used".

No machine was mentioned.

You are entitled to your incorrect, uninformed opinion.

You're right there, no specific machine was mentioned.

Mind you Lyn, the response from Kodichina to the OP was a lot more appropriate than those proffered by yourself.

Thanks for acknowledging my entitlement mate.

It is my opinion that your opinion regarding my opinion is in itself incorrect and uninformed.

But hey....that's just my opinion!

Yes, and the reader is free to assign any level of credibility they choose, to our opinions.

You could go to the trouble of making a stone flour grinder if you have stone mason in your blood line.

They were used for thousands of years before we developed the new stainless steel ones used today.

Or you can cut the seaweed into small pieces then after you get the seaweed totally free of moisture you can use one of these home flour mills.
