Dairy Filling Equipment 

Since 1969 Serac has been an innovative leader and designer of precision built filling machines for the dairy industry. We have a large range of filling and capping machines that cover all types of dairy products from fresh milk to preformed cups for yogurt. All filling systems, including milk bottle filling machines are certified to the 3A Dairy Sanitary Standards.

Choosing the Right Filling Solution

We know that selecting the best solution for your filling needs can be a complicated process. There are many aspects that need to be considered as you decide on the best choice for your unique needs. Milk is a fragile and living product. It is microbiologically very sensitive and it is an ideal breeding ground for micro-organisms. Add to that it is also extremely light sensitive and the choice of equipment and materials play a key role in filling dairy products.

Whether your product is UHT milk, ESL milk, Pasteurized milk, or sterilized milk, it is important to choose the appropriate container and to take all the necessary hygiene precautions applicable during the filling process.

Our engineers, designers and support personnel are experienced in helping our customers understand how each possible variation will affect the ultimate solution. They are skilled at designing the best possible filling system based on your needs.

The Whole Picture

Selecting a filling machine is just one part of the equation; there are other factors that need to be considered. Based on your requirements, what type of environment is necessary inside the machine? What type of treatment is needed for the bottles and the caps? What is the sterilization method and how does it affect the other machine features? What types of cleaning and maintenance processes are required?

Each of these choices needs to be considered individually and collectively because all the pieces are linked and each one has an influence on the entire filling operation. One incorrect choice may affect the outcome of the final product.

The choices will determine run time, maintenance, hygiene, shelf life, cost and much more.

There are many other factors that need to be considered when determining the optimal filling machine solution. Some specialize in the dairy industry and we have been designing machines for over 45 years. If you would like to learn more please contact us for additional information. 

Experience: Over 40 Years in Dairy Packaging 

  • Pioneer in weight filling for milk on rotary machines since 1969.
  • Aseptic filling of UHT milk in bottles (first aseptic line 1978).
  • Proven aseptic experience for UHT milks with more than 35 aseptic lines in production (and 83 in the aseptic field).
  • More than 300 rotary bottle fillers sold in the dairy field.


Wide Range of Products for Filling Milk Bottles & Dairy Cups

We offer packaging solutions for a wide variety of liquid dairy products with various microbiological sensitivities such as UHT milk, sterilized milk, pasteurized milk, ESL milk (up to 90 days refrigerated cold choice), flavored milk, drinking yogurts, probiotics, whipped creams…
Our machines are designed to be suitable with all types of bottles such as plastic (HDPE, PET, PP, PS…), glass and metal.

  • ESC white milks
  • Drinkable yogurts
  • Probiotics
  • Pasteurized
  • Sterilized milks
  • Processed cheese

Technologies in Dairy Filling


It is the only filling technique which controls the product quantity inside the filled container and not before, as is the case for all other filling technologies.
By measuring the weight directly in the container, this technology offer the guarantee that each container is filled with the optimal quantity.

Main benefits of the technology

  • Hygienic solution. No contact between nozzle and container
  • Cost saving thanks to high filling accuracy
  •  Filling traceability thanks to weigh-filling
  • Easy maintenance at low cost
  • Available for liquid products with pieces or pulp

Multiflow: Our Smart Filling Nozzle

Our patented Multiflow nozzle considerably reduces foaming. It is operated by an electromagnet which optimizes each filling cycle according to specific product characteristics. The filling cycle is therefore no longer linear.

  • Magnetic valve > No membrane between valve actuator and filling circuit
  • Optimized filling cycle
  • Less foam, no splashing
  • Reduced headspace in the bottle
  • Hygienic. No retention part
  • Handles a wide variety of products (foamy, viscous, with fruit pieces. …)

Capping and Heat Sealing

Serac designs and assembles various types of heat sealing and capping machines. Depending on the dairy products, it is possible to use hygienic heatsealing/capping turret. Heatsealing parameters or capping torque values can be saved and accessed by the touch of a button.

  • Optimum protection of the milks and dairy drinks

Bottle Transfer Technologies

Serac can transfer any bottle design and material by the bottom or by the neck

  • Any bottle format and design can be transferred

Pulsed Light Cap Sterilization

Decontamination Efficiency

  • Pulse Light decontamination combined with photchemical effect (U.Vs absorbed by DNA: breaking & impossible replication) and photothermic effect: 160⁰C temperature breaking the cell in 300 µs
  • > 3 Log on Aspergillus Nijer Molds
  • > 3 Log on Bacillus Atrophaeus spores

Benefits of Pulsed Light Sterilization 

  • No risk of chemical residue or cap damage
  • No water use
  • 40 million caps warranty
  • Technology can apply for neck decontamination

Making the Right Choice

Choosing the right equipment for your packaging needs can be a daunting task. There are many factors that need to be considered when selecting the optimal solution. Serac has been designing and building filling and capping equipment for over 45 years and we have the experience and the know how to design and build a machine specifically for your needs.
