Fast Line Inspections® has two standard type of machines:

The FLI-SealTester-MAP1 and the FLI-SealTester-MAP3.

 

In both mentioned types we have the size S (small) and M (medium).

These machines are standard production-versions, meaning always the same (except for small modifications here and there in time) and ONLY for gas filled pouches. See the attached brochure.

Some explanation between the differences of the MAP1 and the MAP3.

 

MAP3: 

The MAP3 has three identical measuring-units. The pouch enters the MAP3 at the first measuring-unit. This first unit starts pressing the pouch (with a pre-defined pressure) and measuring it at the same time.

Then the pouch enters the middle position. This second position presses (and also measures to monitor the thickness while pressing) the pouch a little more (all adjustable on the screen), when there is a weak seam, this will cause gas to escape at this position.

After that the pouch enters the third position and is measures equal like on the first position.

When there is too much difference, the pouch is rejected. This difference (tolerance) can be adjusted etc. on the screen.

 

MAP1:

The MAP1 acts the same way as the MAP3.

Measuring1, pressurize, measuring2. And all happening underneath one measuring belt.

So, again you have two measurements, when the pouch is just under the belt and one just before the pouch leaves the belt.

And in between (entering and leaving) some pressure-time (read: time to leak gas) and you can do a comparison of the two values to determine whether the pouch was leaking.

Therefore the measuring belt is a little longer to have more pressure-time between the two measurements.

As you can understand the MAP1 is less accurate than the MAP3 because the time pressure is supplied is shorter than with the MAP3.

 

Main differences between the MAP1 and MAP3:

  1. The MAP1 is a unit that you mount on an existing conveyor at a customer, the MAP3 needs to be put in line (which makes the line longer).
  2. The maximum speed for the MAP1 is 80 pouches per minute, the MAP3: up to 150-180 pouches per minute (depending on product and size).
  3. The belt-speed of the MAP1 needs to be much higher than with the MAP3.
  4. Accuracy on the MAP1 is much lower, but for dedicated customers (vegetables, crisps) more than enough.
  5. Although the accuracy is low on the MAP1 it is still a very good tool to flatten the pouches before entering a Case packing system. (Also minimum and maximum thickness will be measured to prevent oversized pouches enter the case)
  6. Cheaper.

 For the liquid we have the FLI-SealTester-MAP3-SE (MAP3 principle and Special Edition).

The MAP3-SE is tailor-made especially for the liquid industry BUT also very suitable for customers that want to detect very small leaks with gas (grated cheese, chemicals and powders etc.)

Calculation program:

Fast Line Inspections® uses a special software program to determine what the possibilities are with different products.
It shows clearly, in a table, what (and what not) can be detected based on Bernoulli’s Law. The standard info we need for this program:

    1. Size of the pouch (LxWxH) in mm
    2. Allowable pressure while testing in N (Newton)
    3. Density of the gas or liquid inside the pouch (Kg/M3)


      To determine if testing is possible there are some rules:
    4. Is there (enough) air/gas?
    5. Is there an air cushion when you push it? (The belt may not touch the product)

 

Remark:  Desired speed must be within specifications !


With the above information the software program can calculate the size of the hole versus the speed and pressure.
