Filling Monoblock

Filling Monoblock

Used filling monoblock:

A filling monoblock is a machine that encloses other machinery in a single block, usually two or more. It usually plays the function to fill and plug the bottles. If a third machine is inserted, a drizzler is also defined for filling tribute. The monoblock is the essential machinery inside the bottling line since it allows to fill and plug the bottles with a single machine. It can also be composed inside a rinsing machine, assuming this order, rinser, filler, capper.  

How does it work:

This is located at the beginning of the line; usually, immediately after the depalletizer; in the case of glass bottles or after the blow moulding machine in the case of PET bottles. For the new and used filling triblock the operation starts from the rinsing machine if present; and the bottles arrive in a row through a bottle-sized conveyor belt; from here they physically enter the machine through an auger (worm) which positions them at an equal distance from each other. So once inside the screw, the bottle advances until it is inserted into the star, which aligns the bottles; and at this point, the neck is aligned immediately under a clamp; that takes the bottle from the neck and turns it upside down.  

Filling monoblock for PET:

These types of machinery can be both with the bottle gripping at the bottom and with the neck gripping. the monobloc used for PET is a machine that in the past was made with a deep grip for a dual purpose. The first was that the monoblock used for PET could thus be used for both glass and PET. The second was that it was very versatile to perform the different productions. the monoblock used for PET can have two or three or four turrets depending on what is to be filled. It can be both isobaric and flat liquid and the latest generation ones all have a grip on the neck. This is to avoid crushing the bottle during the filling and capping phases.The gripping equipment at the neck is made of 304 steel and allows the use of different bottle formats.  

Different equipment:

The type of equipment is either with deep grip or with neck grip (in this second case usually it is equipment in steel mixed with aluminium). A nozzle enters into the used filling triblock true the mouth of the bottle and in a few moments a strong jet of peracetic; so water or other disinfectant is shot inside the bottle to remove foreign bodies. Continuing, a strong jet of filtered compressed air is blown at high pressure, to dry the same bottles in an instant. Finally, the bottle is put back in position, ready to be moved to the filler. During filling, the filler must absolutely not modify the physical organoleptic properties of the product being processed such as water, wine, beer, milk and oil. It must therefore have a system and components that are consistent and respectful of all health and hygiene regulations required by current regulations.  

Filling Monoblock for edible oil

This type of machine has three turrets, one for blowing, one for filling and one for capping. The triblock for edible oil usually has a high vacuum chamber filling system or a volumetric system. This machine can reach excellent speeds if used well and with proper maintenance. In the triblock for edible oil, the capper can have several applicable capsizes, it is enough to have the correct format changes. This type of used triblock can be designed both for processing PET and glass bottles and cans. Depending on the technology used, the triblock for edible oil can obtain different performances with the same configuration. This used triblock could also have the universal star system to work in different formats as rotary machines.  

Filling phase:

Throughout this the filler must avoid doing essentially these four things:
  • Pollute the product
  • Oxidize
  • Alter the quantity
  • Altering the quality of the product
In the new and used filling monoblock-triblock to give a stable rule, the time between filling and capping must be as short as possible; we are talking about seconds, in which nothing must come into contact with the content. The equipment consists of a variable number of taps or filling nozzles, with different technologies and different predispositions and from these, the product flows directly into the bottle container, brick, can, etc. In the next phase, the capping procedure starts. This is the machinery that mechanically inserts the cap into the bottle after filling and is Placed after the filler. The operation of closing starts from the hopper; a machine attached to the capper that orders the correct direction of the cap to be then fished directly by the capper. Caps must rightly be positioned in the right direction of insertion. From here begins this phase where the bottle is placed on a plate above; which there is a compression tool; and insertion of the cap or a screwdriver in the case of a screw cap. Several turrets can also be arranged on the common machine table of the Filling Monoblock; and, with different types of systems, a rotating turret with two different types of caps mounted on the same bearing axes can also be applied. At the outlet, the bottle is directed to the next machine; which can be a capsule or a wirehooder for sparkling wines.  

Isobaric Filling Monoblock

The isobaric filling monoblock is based on equalizing the pressures between the liquid tank and the container to be filled. This process involves pressurizing the container with gas, such as CO2, before filling, and is essential for filling carbonated liquids such as beer, carbonated soft drinks, sparkling wines and sparkling water. An isobaric filling monoblock is composed of a pressurized storage tank, isobaric filling valves that regulate the liquid flow precisely, a pressurization system that pre-pressurizes the containers and a rotary table for moving the containers through the stations filling and closing. The main advantages of the isobaric filling monoblock include the ability to fill carbonated drinks without loss of effervescence and the reduction of foaming during filling, thus maintaining the quality of the final product. However, the isobaric filling monoblock also has disadvantages, including increased complexity and costs of construction and maintenance, as well as the need for more complex operation and continuous monitoring of pressures. The main difference between a gravity filling monoblock and an isobaric filling monoblock lies in the method of liquid transfer and the ability to handle carbonated drinks. The isobaric filling monoblock, thanks to its advanced pressurization technology, is essential to guarantee the quality of carbonated drinks, while the gravity monoblock is simpler and suitable for non-carbonated liquids.  

Why and how to purchase used filling monoblock

More and more companies are considering purchasing a used filling monoblock. Below you can find a list of our best tips and recommendations to help people like you, who deal with bottling. Buying a used filling monoblock can save you a lot of money. Financially speaking, new monoblocks start to lose value immediately after purchase. With a used filling monoblock you can save several thousand dollars. Already for this reason alone, it is certainly worth buying a used filling monoblock. On our website, you can find out about all the aesthetic and mechanical characteristics of the product you are interested in and we guarantee that you will spend much less on the purchase, compared to a new filling monoblock. By purchasing a used filling monoblock, you can save between 35% to 60% off of the price you would pay for a new monoblock, so whether you want to buy a used filling monoblock to start a new operation or to change an existing one, it is worth taking a look at the used bottling market first. The choice to change models or update existing ones can depend on many factors. The reasons can be numerous. Maybe you have to start producing more than in the past. Or one of the monoblocks has become inefficient, starts causing problems, stops or slowdowns. So much so that it is difficult to reach the daily production volume needed.  

Pre-purchase research on used filling monoblocks

First of all, there are many advantages of buying used filling monoblock. However, there are important things to pay attention to during the purchasing process. While searching for – and eventually purchasing – filling monoblocks, it is necessary to take some important preparatory steps. First of all, during the research, it is essential to have clear ideas about your real needs. You need to have a specific idea of the monoblock and your requirements, looking for it in the appropriate section of the website. Finally, it is important to know the history of the used filling monoblock, if possible the working hours, if the monoblock has been overhauled and maintained regularly and if the maintenance has been carried out by specialized technicians. These are all factors that help in understanding which filling monoblock to buy.  

Used filling machines:

It may be necessary to purchase only single used filling machines for space reasons. Used filling machines can be from many manufacturers and it is important that the manufacturers are still open. This is for both technical assistance and electro-mechanical assistance. Used mechanical filling machines are much easier to use than electronic used filling machines. However, used electronic filling machines are much more versatile and allow more adjustments in the production phase.
