Most tuna product sold in the market take
form of canned tuna. This is the reason why you can see many of those products
in your local grocery store with different brands. There are many factories
with canned tuna production line
around the world even though actually the tuna itself comes only from several
countries. Now let us see how those factories create canned tuna using their
production line.
How Canned Tuna Production Line Make Their
Product
This next line is the pre cooking line
where tunas will be cleaned before being cooked. The tunas will once again be
dumped into double conveyor from the bins. Tunas that have weight more than ten
kilos which already collected separately before will need to go through the
cutting line. In this line the tunas will be cleaned from its head and tail
then it will be cut into loins with suitable size to match the other tuna’s
size.
Meanwhile the tunas that have been dumped
into the double conveyor from the bins will be cleaned manually by factories
worker in separated canned tuna production line.
In this cleaning line all heads, tails, skins, and dark meat are removed from
the tunas thus it will left the line in clean loins form, similar to the
previous size.
Frozen tuna which comes from the fishermen will be brought into the factories using truck. After they are arrived, those bins will be removed from the truck and stored inside the factories storage or go straight to the canned tuna production line when needed. In the production line, first they will be separated according to their sizes. The content of the bins will be dumped into double conveyor to be taken to the shaker machine. This machine will then align the tuna so it can fit with the right position inside the elevator. This elevator is the one that will bring those tunas into the sizer machine.
The sizer machine will then separate the tunas according to their sizes. Tunas that can fit into the sizer are only tunas that have weight less than ten kilos. For tunas that have weight more than ten kilos, they will be collected separately to be cut later in the pre cooking line. Meanwhile tunas that can fit into the sizer, would then be put again into the bins to be taken to the next canned tuna production line.
After being cleaned, now it is time to put
the tunas into the pre cooker. The tunas will be delivered using racks into the
pre cooker which will steam them in specific duration suitable for their size
to cook them. The pre cooker will also cool down the cooked tuna before being
taken to the next canned tuna production line.
All of those cooked tuna will then be put
into sanitary conveyor which will take them into the filler machine. This
machine is the one that will insert the cooked tuna into empty open top cans
according to its capacity. With specific setting, the machine will be able to
fill all of those cans with consistent weight thus all of those cans will have
the same filling.
Next those cans of tuna will be taken into
the oiler machine which will put oil inside the tuna with specific amount.
There is specific headspace which already set into the machine so all cans will
have the same headspace left after the oil is inserted. Last the cans will be
brought into the closer machine which will close the cans and vacuum it so
there is no air left inside the headspace of the cans. With this production
line, complete product of canned tuna is created in the factories.
After the complete product of canned tuna
is created in the factories, now they are ready to be send into the supplier
which partnered with the factories. Those suppliers would be the one who
delivered all of those canned tuna into the customer by sending them to the
grocery stores and supermarket. You will then get to pick up those canned tuna
into your grocery to be added in your meal of that day. So now, when you do
pick up one of those canned tuna in the grocery store, you already know the canned
tuna production line that it going through.
