In Spain, the canning industry is an ancient one.It reached the territory by hands of the Phoenicians. Thanks to the intense trade that took place between Carthage and Rome, having means of food conservation, was a necessity. As one might imagine, it was a very rudimentary process as the first canseamershad not yet been created.

Today, canning remains essential, but since the invention of the first tin in 1731, canseamers have undergone very important changes, and today more than ever, they are crucialfor the food industry sector.

What are preserves?

The term preserve is defined as the process in which food is subjected to manipulation with the aim of extending its shelf life. The idea is that the food in question can last longer in storage, but without losing its freshness, quality and nutritional value.

Main conservation processes

  1. Drying and dehydrating

This method of preservation is one of the oldest, when can seamers were notyet on the market. The water that food contains is one of the main causes of its decomposition.

When some food is subjected to a dehydration process most of the water is removed, thus reducing the chances of it decomposing.

  1. Salting and Smoking

These methods have also been used for a long time, in general, it is a process in which salt is added to the food, usually meats or fish, to prolong its shelf life. When salt is added, in addition to preventing germs from proliferating, drying of the food in question also occurs.

  1. Canning and bottling

Theseare the most widely used food preservation techniques in the present day. This is because they are very useful and versatile, as theycan be appliedto almost any type of food. When food is cannedit is vacuum sealed, this provides you withthe assurance that the decomposition process of the food will be prolonged.

Thanks to the vacuum packaging process, which is used in almost all canseaming machines,the oxygen is removed from the container. This means that all organismsare eliminated, which reduces the process of food breaking down.

As for bottling, the process is similar to vacuumpackaging,but in this case the food is placed in bottles or other glass packaging, and not in cans.


Fanser, a market leaderin the sale of canseaming machines

In the modern food industry, the entire process of filling and sealing cans is automated. In today’s market there is a high demand for can filling and can seaming machines,which optimise the process of producing canned foods.

Fanser is a front-runner in Murcia in everything related to the manufacture, repair and sale of canseaming machines.Fanseroffers a wide range of models that adapt to the needs of its customers.

Cylindrical can seamers

A canseaming machine,is one that, as the name suggests, is responsible for sealing thetin, can, or container. As closure is the process through which an airtight seal is made between the bottom of the can and the bottom of the machine.

Depending on the type of cannedcontainer to be used, a specific type of closure will be required. Thus, you can find large units of seamers, on the one hand, the seamers of irregular cans and, on the other, the seamersof cylindrical cans.


Cylindrical can seamers in the food industry

Almost all tins have a cylindrical shape, this is why cylindrical can seamersare the most common on the market. The reason that cylindrical tins are used repeatedly is because, the process of filling and then sealing is easier when it comes to a cylindrical can.

Types of cylindrical can seamers

Cylindrical can seamers are classified into two types:

  1. On the one hand, the type of cylindrical can closure in which the can rotates while the sealing process is carried out, this is also called rotary can closure. This type of machine can have one or more heads, and the speed of seaming can be very high.
  2. Cylindrical canseaming machines in which the closure is made witha stationary can, i.e. it does not rotate. The can, during the sealing process, remains completely motionless.In this case it is the machine’s sealing head that will move to carry out the closure.


Advantages of cylindrical can seamers

The greatest advantage of cylindrical can seamers is that these types of machines offer uniformsealing of the highest quality. They do so regardless of whether it is donewith a stationary or rotarycan.

In the case of a cylindricalseamer with stationary cans, an extra advantage is obtained.The additional advantage is the fact that the packaged product will not undergo a centrifugal effect, whichusually happens in the rotary cylindrical canseamers.
