Yogurt is a product that results from the fermentation of milk by certain bacteria, mainly Streptococcus thermophilus and Lactobacillus bulgaricus. Yogurt gets its signature sour flavor and thick consistency from the bacteria’s conversion of lactose, the sugar in milk, into lactic acid. Creamy and full of protein, calcium, and probiotics (good bacteria that aid digestion), yogurt is a great food choice for maintaining a healthy digestive tract.
Probably what brought you here is your curiosity about the machinery and tools used in yogurt manufacturing and packaging procedures.
In this post, we’ll cover the details you need to know, including an overview of the most common types of yogurt packaging machines used by dairy manufacturing facilities.
Which Yogurt Packaging Steps Are Most Crucial?
First, what kinds of packaging procedures are necessary for yogurt? Only then can we proceed to describe the various types of machinery used for packaging yogurt. Beginning with the most basic level of packing and progressing through basic and secondary, we provide a comprehensive overview.
Yogurt’s Main Packaging
The main step in packaging yogurt is choosing and assembling the containers, which may be anything from glass jars or plastic cups to bottles or pouches. After that, they are cleaned to ensure they are safe for use. Two of the most common types of packaging are thermoformed inline form-fill-seal cups and pre-formed cups.
For a tight closure, the containers are topped with lids; foil lids are usually heat-sealed. Afterwards, labels are placed to convey important details, such as the brand, nutritional value, expiry date, and ingredients. Then, to facilitate traceability, production dates, batch numbers, and expiration dates are coded and marked.
Secondary Yogurt Packaging
Following the main packaging comes secondary packaging, which serves to protect the product further and provides a surface for print and essential info. The process also includes consolidating smaller yogurt containers into bigger ones for better shipping and handling. The use of cardboard sleeves for packaging yogurt cups in multiple configurations is a typical example of this type of application.
Inline Form-Fill-Seal Machine
Among thermoforming machines, the Form-Fill-Seal Machine stands out due to its combined filling and lid sealing stations, along with its sanitizing mechanisms. Inline formed cups are the focus of form-fill-seal machines.
Form-Fill-Seal Machine
Ensuring food safety, prolonging product shelf life, and adhering to regulatory requirements all require excellent cleanliness standards for these devices. Maintaining quality control, preventing cross-contamination, and maximizing economic efficiency through waste minimization and expensive recalls are all benefits of high hygiene standards. The production of safe, high-quality food items, including yogurt, depends on maintaining a sterile packaging process.
While most yogurt comes in plastic containers, you may also get it in glass, composite materials, or even pouches. One common kind of packaging is the form-fill-seal cup or pre-formed cup. Next, the lids are placed on top of the containers and often heat-sealed to provide a secure seal. Important information, such as the brand name, nutritional value, and expiry date, is included on labels.
Pre-Cup Filling and Sealing Machine
In contrast to FFS machines, this machine works with premade cups. In terms of sanitation and safety, this machine is built and designed similarly to the FFS machine. It is possible to construct filling and sealing machines that preserve hygiene standards while filling and sealing yogurt cups.
Carton Sleeving Machine
Machines that specialize in wrapping protective and sleeves around yogurt cups are carton sleeving machines, wrap-around sleevers, or wrap-around cartoning machines. These machines can be used for both solo and cluster yogurt cups.
Wrap-Around Case Packing Machine
Tertiary packing often uses wrap-around case packers, sophisticated machines that construct, fill, and seal cases using a single sheet of corrugated cardboard.
Because pre-formed or free-flowing cups are not solid containers, they might be difficult for a side-load case packing to stack and fill into cases, which is why wrap-around cases are usually preferred for yogurt packaging.
Additionally, wrap-around case packers are particularly popular because they offer strong protection, reduce material consumption, and work quickly. The products are neatly packaged and presented professionally.
This machine can accommodate a wide range of product shapes and sizes, making storage and transit more efficient. The yogurt business can save money and enhance logistics by using a wrap-around case packer, which offers the traditional advantages of the case while being efficient and adaptable.
How is Yogurt Packed?
1. Prepping Container: Getting the yogurt container’s shape and material just right.
2. Filling Product: The Automatic yogurt cup filling and sealing machine dispenses the product into containers accurately and cleanly.
3. Lid Sealing: It is common practice to use heat sealing to form an airtight barrier after applying and sealing lids.
4. Label: Each container has a label that details the contents.
5. Code and Mark: Batch numbers, production and expiry dates, and other such details are included to facilitate tracking.
Common Yogurt Cup Materials
- Glass: Helps prevent oxidation while providing a high-quality finish.
- Plastics: Because of their low price, long lifespan, and adaptability, it is the ideal option. Some of the plastics include polyethylene terephthalate (PET) and polypropylene (PP).
- Pouch: Yogurt drinks in particular often come in flexiblev pouches.
- Composite Materials: Maximize quality and longevity by combining various materials.
