Metal Detector Machine

Sorry, but its really impossible to understand what you need by your post. Please, reformulate your question. Use spanish, or even portuguese if you'd like...

We are packing spices in metalized film pouches so we need metal detector machine which can detect metal in spices not in film. The metalized film itself having aluminium so I dont want to sense metal in film.I want to sense metal in spices.

Please guide me.

Sandeep,

See my original response. You"ll need a "ferrous in foil" detector.

See you sales rep because there is more than one way to do this and each has benefits and shortcomings. I have a couple of ferrous in foil machines. One is simply a standard Safeline that I have the phase discrimination circuit modified to null out the aluminum. The Loma IQ magnetic style that I have needs to run really too slow

Are you sure it would not be possible to run your product through an in-line detector prior to packaging? There are many in-line food and pharmaceutical detectors that that might work for you.

Dear switchman,

which are those in line food and pharma detector. Please give me an idea.

Sandeep,

There are so many unknown variables that it is difficult to give you an answer that helps.
There are some things you must consider such as:

How are you packaging? Are you using an automatic scaling / bagging machine?
Are you putting in a detector on an existing line? If so then you already have line speeds and product quantity established but you have to figure how to get a detector inserted into the line.
Are you putting in a new line with new conveyors? This gives some ability for flexibility.

I put in a couple of these free fall units and really like them... you just have to be able to drop thru. I put one inline between my flour weigh hopper and mixer with a simple diverter.

I also have the newer Lock Met30 detectors. This might do for you because it will sense the aluminum wrapper and cancel for it. These will run pretty fast too, I run wrapped product (here ours is poly film but not metalized) at 220 packages a minute through it.

Hope this helps a bit more.

Dear all

Please let me know whether this metal detector machines can detect stone powder get mixed in material. Because one my coligue is saying that it cant sense stone powder. But magnets can sense stone powder . Please let me know.

Sandeep,

Magnets cannot sense stones or stone powder unless perhaps they are very high in iron or metallic content. Hold an average rock up to a magnet and you will see this.

If you are needing this level of detection you may need an x-ray machine which would detect the density of the stone but these are quite expensive. Typically you would want to catch the stones prior to processing.

Each facility should have a developed quality assurance program and that should also include hazard analysis and critical control point (haccp). Using this method you may have to develop different procedures for food safety based on your regulations.

If you find that your product is getting a lot of contamination from stone then you will need a method of screening or sifting.

Do a search on Google for "ferrous in foil metal detector". Safeline, Lock, Ceia, Cintex and others all make a ferrous in foil detector. Some use a standard type aperture head with phase discrimination to block the aluminum...these work better to catch stainless bits but are hard to catch other metals. Others use big magnetics but then these work great for chunks of bearings and other stuff...but won't get stainless.

Certainly the best thing to do is to contact your local supplier and find out what options they have.

Photo recognition. take picture.

sandeep lokhande Check with your film supplier, they can tell you what they use for detection. Jerrell

If the contaminants you are expecting are predominantly ferrous then a (strong)magnet will do it.

Sandeep lokhande The latest greatest technology may not be the best solution for you. Install an air lock so you can remove all foreign materials from your line. You will be able to discriminate out foil and most any thing else including product that is mis-sized and undesirable for packaging by simply making flow adjustments. These are used in many stages of tobacco manufacturing to cull out undisirrables such as after reclaim to remove anything heavy such as sand or metal and other particles such as paper, foil, fibers hair etc. If you install a detector then you still need to install an ejector. The next step is to install reclaim equipment to cut down on losses by opening the pouches and separation of product from packaging materials. Now your back to square one so install the air lock in your main feeder to prevent the contaminates from being packaged and a downstream detector to verify proper operation. Jerrell

You've peaked my curiosity. I've never worked in the tobacco industry but I've never run into like you described in food. Can you provide a link where I can take a look at something like you're talking about? While I absolutely must comply with HACCP, FDA, etc. guidelines, I'm all for investigating anything that speeds things up or reduces costs in the process in our plants.

Switchman The air lock I'm speaking of uses a cabinet that has vacuum draw your product through it causing the product to float and tumble suspended as it crosses the chamber. There is an up flow of vacuum that draws any light or large surface area particals up and out the top and a sieve at the bottom that allows any small heavies or particals that don't have enough surface area to be carried by the vacuum to drop out the bottom into a sealed flap style air lock to be carried away. Any large heavies will remain in the sieve. The vacuum can be adjusted so only the size particals you desire remain suspended and carried out by the horizontal flow of vacuum. The cabinet is constructed with lexan sides so that you can monitor and adjust the flow to adjust to meet your needs. The cabinet size can be made to suit your product flow. You should be able to research used tobacco machinery and find several versions of this design. Jerrell

I agree with Switchman , I have several LOMA's in my work area and they should do the job. There is no point putting the metalized film ( wih spices inside ) through metal detection. Its better to have the metal detection upstream. With both horizontal and vertical form filling, you can have your metal detection system above your auger filler . YOu might need a magnet assembly prior to your metal detection system since you dont want the magnet to go off all the time. I would suggest using ERiez or Ding Rare earth magnets for your application.
