The industrial bagger is present in different industries that handle bulk. We explain what a bagger is and how it works, before delving into the different types of industrial baggers that we can find.
What is a bagger
The industrial bagger is a machine specialized in a very specific phase of the industrial process: the packaging of the product. The function of the bagger is to easily introduce the bulk product in different sack formats. Depending on the bulk in question, we will use one type of bag or another.
The product can be marketed in different formats and presentations: large, small, medium, 20, 30, 40 kilograms … This brings us to another special function of the bagger. In addition to serving to easily fill the bags without having to make efforts, we also use it to calculate the amount that we have to enter in each bag.
The bagger has a double function: to pack and dose the product. And we also do it with little physical effort, even in some of them, as we will see later, in a completely automated way.
Baggers are in all industries where large quantities of bulk are handled. Said products can be food or non-food. Thus, we have baggers in the FOOD INDUSTRY SUCH as FLOUR and cereal factories, or in packaging machines for legumes and nuts; but also in aggregates, cement or pellet plants, all of which are transported and marketed in bulk or in bags.
Baggers can use two types of bags. The open mouth bag and the valve bag. The open-mouth bag has a completely open end, through which the product is introduced, and another completely closed. That open end is later sealed so that the product does not spill. The open mouth facilitates filling in the bagger. This type of bag is the one normally used in the SEMI-AUTOMATIC BAGGER because it is easier and faster to place.
The valve bags differ in having a fully closed side and the other end is also sealed, except for a small opening or valve through which the filling occurs. The valve bag has the advantage that, as it is being filled, the hole closes automatically, thanks to the pressure of the air that comes out. At the end of filling, only a small hole remains which is very easy to seal. Quite the opposite of what happens with the open-mouth bag, in which the end must be completely sealed.
How a bagger works
The operation of a bagger is not difficult to explain. To understand how it works, we just have to think of a large funnel where we deposit the liquid that is then poured into a bottle.
In the baggers we find a HOPPER, which is a receptacle located in the upper part, where the bulk is introduced. The hopper has the capacity to contain a large quantity of product, enough to be able to fill several bags. At the end of the hopper, there is a narrow mouth that serves to fill the bags. These are manually or automatically placed in that mouth for filling.
Types of industrial baggers
There are three types of industrial baggers:
The semiautomatic baggers are very common in small industries loose foodstuff, but can also be seen in processing plants plant residues (pellets). In semi-automatic baggers, the filling process is automated, but it is necessary to place the bags manually on the filling stand. The filling of the hopper is done with a conveyor or endless belt that pours the bulk that will later be packed in the bags.
Semi-automatic baggers are fairly compact machines, which can be placed anywhere in the factory. It is a very versatile tool with easy maintenance.
Automatic bagging machines
In automatic baggers the whole process is automated. The hopper is filled by means of a belt or endless, and the bag is automatically placed by arms that put it in place and hold it until the filling is finished. The bag then goes to the sealing machine to complete the process.
They are simpler and less common machines. In the filling and bagging process, it is done by gravity. It includes a dispenser in the lower part and is filled when the operator opens a valve that is in the hopper. The bag is then placed in the exit hole and held until full. The process is completely manual, there is no electrical or electronic mechanism.
Baggers can also be classified by the type of bags they use, which can be valve or open mouth. We can also differentiate them according to the industry to which they are intended. The baggers for food bulk are built with materials typical of this industry, such as stainless steel for food use. We will also find baggers designed and manufactured in a more robust way in the heavier bulk industries, such as aggregates.
The bagger is a type of machine that is also custom designed. Depending on the location and material to be handled, a custom design is made from the factory. The rest of the complementary machines, such as augers or conveyor belts, are also taken into account when designing and manufacturing the baggers.
