The Shredder - Ultimate Burley Machine

We make and use a lot of burley.  Having upgraded to the use of a commercial mincer we still had the hazardous use of a band saw to cut up the frames, etc to a manageable size that fit into the mincer.  I don’t think it is a matter of if, but when a serious injury would be caused by handling wet frozen fish in the presence of a moving saw.

Dean owns and runs an engineering workshop and turned his mind to a better option for making large fish into small pieces.  The brief was to be able to load a whole frame and turn it into something that could be minced.  After quite a bit of research the concept of the Shredder was born.

It started with the steel plates that could all be cut out of a single sheet using the computer controlled flatbed plasma cutter.  Forge the axels and gears, assemble and lathe for consistency, add the bearings, construct the mounting box and the cutting bed was made.


Next was the housing as you wouldn’t want to get any part of your body near the cutting bed.  Add the motor and chain drive and it was ready for a test.

Let’s just say the Shredder is evil.  It absolutely destroyed anything that was put in it to make chunks 10mm by 6mm.  The test was a complete success, although some minor adjustments will make it even better.


Next up is the hopper, stand and wheels so it can be moved without the forklift.  Dean and Wal should be congratulated in making such an awesome device so that all fish waste is reused and nothing is wasted.

Very funny, but has anyone told you that you have a sickness Mick....haha.

We used an industrial wood chipper last year.....holy crap, once it grabbed the tuna frame, it ripped through and smashed it out the other side at about 100 mph......I was holding the bin the other side, put me on my arse.....

Decided burley was too hard after that....

Are you freaking serious?

You call that a shredder? C'mon Mick, it hasn't even got a poonsy turbo 4 cylinder engine, let alone a blown Hemi V8! I would be embarassed putting up photos of that girly kitchen appliance, it has no manliness about it whatsoever!

Anyway, only poofs use burley, real men just chuck C4 over the side.....


Seriously, that is awesome. Next time a whale washes up at Scarborough, I'm giving them your number.

Next time a dead whale washes up on a local beach can I give you a call for some jointly advantages endeavour.
I'll supply the raw product (blubber), you supply the means (shredder) to produce the required end product.
How long do you think it would take to get through 500kg of blubber. LOL

A new industry is born

Sun, 2015-05-17 16:39

Need drives innovation (I forget who said that) but Mick C had a need to make a lot of burly and wullah, he got of his backside and used some of the grey stuff to come up with a solution to make lots and lots of burly quick.
Bloody great job.
And as I said previously just wait till the next dead whale washes up on the beach.

Burley Sales and Shredder Hire

Sun, 2015-05-17 19:16

Thanks for all the great comments.  I think there are a lot of rules and regulations around selling fish products so I am not sure if I can.  Worth a look though and I will check it out (Fisheries have tentitively agreed to allow me to "dispose" of fish skeletons under its "send us your skeletons" program).  Much better than a landfill in my opinion.

As far as renting it goes, I have no idea.  Its processing rate is about 100kg per hour but there are bound to be rules around commercial use of this as well.  I definately think this is a good service and The Shredder is better being used than sitting dormant in a shed.  Another one to look into, with no intention of ripping FW Members off.

WTF was going through your head to produce that.

Have a problem, come up with a solution, but that is one serious carcass destroyer. Dont let the greyhound industry get near that!!!!!!!

Just wondering

Mon, 2015-05-25 09:07

And I am by no means mechanical, but it looks like the "shredding" action is a rotation inwards (Just looking at the cutting face on the metal)

Why is it that the debris collects on the sides. Or have I got the mechanism totally F.Upped (which would not surprise me or others that know me!!!)

Shredder Update

Wed, 2015-05-27 19:29

Thanks to all for the comments on the Shredder.  Thought I would post a bit of an update on a few things raised by Members.

We are going to create a new set of cutting plates that have one tooth per plate and are orientated on the shafts to spiral in.  The purpose of this modification is to give more cutting power and force the fish down into the base of the cutting deck for a more efficent process.  There was nothing really wrong with the plates as they were, but we can make it better.

Cransy1 - yes, the rotation is inwards but there are spacers on each shaft so some debris will work their way to the sides via the gaps caused by the spacers.  Not a major problem and the Shredder is easy to clean with a hose after use but the above modification should fix this.

I have had a look at what it would take to get the relevant permits to sell the product produced by the Shredder.  It seems that commercial use would be regulated by s80 of the Fisheries Management Act where the discretion to grant a permit sits with the Chief Executive.  I see no valid reason why a permit would be refused but there is the whole process to go through.  We would also need to build some "packaging" equipment, and obtain appropriate packaging bags, so it was not a totally manual process.

In order to consider commercial production a bit more I would need some idea of the price people would pay for the product.  My initial thoughts are $7.50 - $10/kg for the raw product and $12.50 - $15/kg for "MickC's Ultimate Burley".  What do people think?  It would have to come frozen so kilogram weight of the blocks is also a consideration.  Would people want the "Big Angry Fush" 5kg blocks, that could be produced at a reduced rate per kilo because of the size?

Hire of the Shredder could be contemplated if the s80 permit is obtained.  The question is what would people be prepared to pay per hour for the use?

Can we make and sell more Shredders?  Potentially yes, but not for a while.  There is a bit of testing and evaluation of the prototype to occur first.

I really appreciate the feedback and any replies to my questions above.

Looking at the end product

Thu, 2015-05-28 08:11

Price seems reasonable. It looks exactly what I would need in the Burley bomb chasing whiting offshore. Just add a drop of oil or 2.

Ill be in!!

PS: yes thanks for the mechanical info. I was wondering how it worked, and the debris on the sides had me perplexed. Didnt think cleaning would be an issue. You would have to plan that, or the whole thing would turn into a maggot farm. Thinking about that, the hezza fishos might be interested in that as well

I would be quite prepared to pay $20 - $25 for a decent sized block - would have thought one around 2.5kg would be perfect for the average session starting with it being frozen would ensure slow release

Make some frozen ones up the a tad smaller than the burley buckets that most guys have out on the transom made from 100mm conduit. Slide them in and mash away.
