Powerful food sealer, homemade - anyone interested building one? Answered
After finding out my favourite catch of a good fishing day won't fit into any normal foodsealer bag or tube I wasted a few hours thinking about the problem....
These normal food sealers are like an injet printer - you pay the real price through the consumables.
And with those I already noticed cheap only too often means bad quality unless you got the bargain price for ordering in bulk.
My favourite kebab shop has a big commercail sealer that is used for packing stuff for other stores and catering.
So I ordered a fresh and extra spicy kebab and asked if it would be possible to take a closer look on this sealer thing they use.
No problem for a good customer like me but of course I was asked to finnish my kebab first and to use the provided gloves if I want to touch anything - freshly sanitised and so on....
I was surprised by two facts:
a) the price of close to 5grand
b) the simplicity of the thing
Was not allowed to take pictures, so sorry for that as this time I really wanted some.
From what I could gather without taking it apart is that 3mm stainless steel is used for a big "pan".
About 80cm long, 50wide and 30 high.
On the outside several pieces of square tubing, most likely to prevent warping under a high vacuum, although 3mm stainless already takes a lot.
The lid was 5mm stainless with several thick viewing windows in it to check the correct placement and sealing action.
Of course I am not really planning to go that big, for now anyway.....
For the inside there were several frames available to cater for pots, bags, loose stuff and so on.
Purpose of these frames was to make sure the bag used will be held with the open end inside the sealing section.
The heating element or strip was on the floor of the pan and a push bar was mounted to the lid to give the desired pressure once the lid is locked in place.
Time for the actual heat sealing of the bag is started with two switches on the locking clamps.
The top bar is mounted with two springs, I assume to allow for just enough pressure for the air to be sucked out of the bag while still performing a good seal during the heating.
Getting suitable parts can be as easy as to salvage an old vacuum sealer and to use a frying pan or as "complicated" as building one from scratch with a powerful vacuum pump or old fridge compressor - I like the second better ;)
But after a few Instructables and still several in the making I thought the old thing of "group therapy" would be nice for this one.
We are from all over world and certainly not everything I can get around the corner is available for someone from the remote areas of India or South America.
And I am almost certain that someone might have a great idea on what common and easy to obtain stuff can be used for the vacuum chamber for example.
Another one might already have a heating wire solution for the sealing that is cheap and reliable.
You get the picture....
Why would I want to do this with several people from all over the world, maybe even fighting language problems?
The benefits are there is you look for them ;)
With a limited set of "rules" on certain areas of the project we get the benefit of:
a) Having an instant proove of concept with actually working devices for our readers.
b) A much greater chance that anyone can repeat the success at home and with already several working designs to choose from.
c) A chance of actually "working" together on something with some of the great people here!
d) Something new that is not a contest or challange.
e) Hopefully a lot of fun on the way :)
Of course and in the case this actually catches on, it would be great to somehow create a collection for this project.
Like when you add several Ibles to your collection but so everyone who made one can add it.
So anyone up for it?
