The FASA RFS 40 Rotary Filling and Sealing Machine is a machine that will fill pre-existing containers with past-type foods such as butter, margarine, spreads, and curd. It uses accurate volumetric dosing to fill and seal tubs or cups, and can operate in container sizes of 100 to 1000 grams. This versatility qualifies it as a good choice with regards to numerous food wrapping requirements.

The machine is made of stainless steel with a convenient touch screen so it is not only durable but also easy to use. It has various shapes of containers- rectangular, square, round; it can seal them by using heat- sealing foil or lids. The size of portions can be changed, as well as the output can reach up to 40 portions per minute thus the production does not decelerate and is still achieved at the right accuracy.

Core features and technical specifications

The RFS 40 is a rotary filler/sealer that is designed to work with paste-like products. It enables various container shapes and sizes, and allows variable dosing to suit various production requirements.

Container compatibility and dosing options

This machine operates with ready-to-use containers, such as plastic tubs out of polypropylene (PP). It comes in the shape of a rectangle, square and round hence easier to adjust to various packaging requirements in food production.

It is accurate and dosed volumetrically. Feeding is available in two different ways, a hopper auger fed or a direct line feed via a resting tube. The dosing components are stainless steel, this assists in cleaning and also prolongs the functioning.

The machine package sizes are between 100 and 1000 gram package. Depending on the height of the machines, operators can customise their portion sizes and hence, it does not take hours to switch between products.

Performance metrics and output rates

The output will vary according to the size of the portions and the thickness of the product. In smaller packages (100250 grams), it can strike 40 portions per minute. The medium sizes (300-500 grams) are slightly costly, about 25 per minute, and the largest ones (750-1000 grams) cost as much as 15 per minute.

This scalability allows you to produce as required. With the rotary table design, things are in motion, which increases the throughput and maintains filling and sealing unchanged.

Automation and control systems

RFS 40 is based on PLC with HMI touch screen. The process can be programmed and monitored without having to be a tech wizard as well.

It has safety built in, including machine covers to the CE standard. Container sensors and options such as UV lamps to hygiene are in place. An inkjet printer can as well be attached in order to label containers with product details or batching.

Key components and material handling

The RFS 40 is based on accurate and durable components when it comes to filling and capping tubs or cups. It regulates the movement of the products with a choice of various consistencies and leaves everything safe and hygienic.

Hopper with augers and feeding mechanisms

The two-feed procedures are a hopper with augers or line feed directly through a resting tube. The hopper augers help in mixing thick products such as butter so that it does not disrupt the texture and the flow remains consistent.

It is an ideal setup when dealing with paste-type products and prevents interruptions. The hopper and augers are made of stainless steel, thus they can be washed easily and in the long term.

Dosing units and product consistency

It has a volumetric dosing unit constructed of stainless steel. It dispenses the right amounts, thus you do not need to be afraid of spills or overfills.

The dosing system has a pneumatic compensator that controls the pressure. This is useful when the product consistency varies e.g. when the batches of butter or spreads differ. It is a fast changing system that maintains the fill level at the appropriate level.

Stainless steel components imply that it is easy to clean them by then cleaning them and the hygiene is also easier to maintain between the shift of the products.

Container handling and safety features

The containers proceed in the filling process on a rotary table where everything flows well. Sensors identity the presence and position of each container to prevent errors during filling and they are also used in sealing containers.

Safety covers do not affect the operators as they are in accordance with the requirements of the CE, yet they can be readily serviced.

It has an optional UV lamp to reduce contamination by microorganisms. To seal, heat-sealing foil or lids containing aluminum foil can be used to ensure secure sealing.

Packaging and sealing solutions

The RFS 40 accommodates various types and methods of lids and containers. It also fits or adjusts appropriately to different packaging requirements whilst ensuring protection of products and remaining hygienically safe.

Lid materials and options

This machine works with several lid materials. Aluminum foil lids are used for heat-sealing, giving a strong barrier and longer shelf life. They’re pre-cut for quick use.

It also supports pre-formed plastic lids, like PS (polystyrene) lids. Using both aluminum foil and plastic lids lets you tailor packaging for different products and customer preferences.

Lids are applied seamlessly, so products are securely closed for transport and sale. This kind of flexibility is useful for a variety of paste-type foods.

Sealing technologies employed

The RFS 40 uses heat-sealing technology to secure foil lids on plastic tubs or other containers. The process melts the foil’s seal coating, bonding it firmly to the container rim.

Heat-sealing is carefully controlled to protect the contents. An airtight seal is key for products like butter and margarine.

Volumetric dosing and container sensors help cut waste and make sure lids fit right, which keeps packaging efficient.

Package sizes and shapes supported

The machine can fill and seal packages from 100 g up to 1000 g. It works with rectangular, square, and round tubs or cups, all pre-made from materials like polypropylene (PP).

Switching portion sizes is simple—just adjust the machine’s height. Volumetric filling keeps doses consistent across all sizes.

This flexibility lets producers meet different market demands with one system. Stainless steel parts and safety covers help with cleaning and maintenance, and keep things up to industry standards.

Manufacturer profile and industry applications

The RFS 40 Rotary Filling and Sealing Machine comes from a company focused on robust design and efficient packaging. It serves a range of food products while sticking to high safety and quality standards.

About FASA AB

FASA AB, based in Lithuania, specializes in packaging machinery. They put a lot of emphasis on stainless steel builds and tough machine bodies, which means better hygiene and longer life. Controls are user-friendly—think PLC and touchscreens—so operation and maintenance aren’t a headache.

Machines like the RFS 40 are built for today’s production needs. Adjustable portion sizes and versatile feeding options are standard. Integration with production lines is smooth, and the machines handle paste-type products well.

Target product types and industries served

The RFS 40 fills and seals tubs and cups, mainly for butter, margarine, spreads, edible fats, curd, yogurt, and processed cheese. It works with pre-formed plastic containers (polypropylene, or PP) and uses aluminum foil or PP lids for sealing.

This machine is aimed at dairy and food processors who need precise dosing and high output. It’s a good fit for producers who want to package paste-like products reliably, with minimal waste and strong packaging integrity.
