Comprehensive Guide to Yogurt Packaging Machines

Among dairy packaging machines, yogurt is a product that is loved by consumers. As a packaging machine for dairy products, yogurt packaging machines provide new solutions for yogurt packaging. The emergence of yogurt packaging machines has greatly improved packaging efficiency and attracted more and more small entrepreneurs to invest in the packaging machinery industry. This article will give you a detailed introduction to the working principle of yogurt packaging machines, what machines are suitable for packaging yogurt, etc.

Working steps of yogurt packaging machines

Container supply link

The operation of yogurt packaging machines starts at the preparation stage of packaging containers. Whether it is common plastic cups, cartons, or different types of containers such as plastic bags, they are all transported to specific locations in an orderly manner through specially designed conveying devices.

Yogurt filling steps

Yogurt is accurately transported from a special storage tank to a filling device through a pipeline system. Modern advanced yogurt packaging machines are equipped with a high-precision flow control system, which can accurately pour yogurt into the corresponding container according to the pre-set capacity standard, so that you can control the gram weight of each package accurately. In addition, during the filling process, in order to ensure the uniform texture of yogurt, some packaging machines are also equipped with special stirring devices. During the filling operation, the yogurt can be effectively prevented from settling or stratifying, so that each packaged yogurt can maintain a high degree of stability in quality.

Sealing and sealing operation

After the yogurt filling is completed, the packaging machine immediately enters the sealing stage. Different types of containers have different sealing methods. For plastic cups, heat sealing technology is usually used, that is, the sealing film is heated so that it fits tightly with the cup mouth under high temperature to form a firm sealing effect. Carton packaging may use glue sealing or folding sealing to ensure that the sealing of the carton meets the requirements. Plastic bag packaging generally uses hot pressing sealing, using high temperature to melt the bag mouth and stick together to complete the sealing process. During the entire sealing process, the packaging machine strictly and accurately controls key parameters such as temperature, pressure and time to ensure that the firmness and sealing of the seal are in the best state. For example, if the heat sealing temperature is too high, the packaging material may be deformed, which will not only affect the appearance of the product, but also have a negative impact on the sealing effect; on the contrary, if the temperature is too low, the seal may not be strong, which may lead to serious problems such as yogurt leakage or deterioration.

Labeling and coding process

After the sealing is completed, the yogurt product is conveyed to a special labeling and coding area. The packaging machine can automatically label the yogurt container, which requires the use of a labeling machine. These labels contain rich and important product information, such as product name, brand, ingredients, production date, shelf life and nutritional information. The coding device will clearly and accurately print the batch number, production time and other key information for product traceability on the surface of the container. The accuracy and clarity of these labeling and coding information are extremely important for the brand image of the product and the normal circulation in the market. If you need to be equipped with such a packaging machine production line, you can ask the packaging machine manufacturer whether these configurations are available.

Finished product output and subsequent packaging

Finally, the packaged yogurt products are output in an orderly manner through the conveyor belt in a predetermined order, and then enter the final sorting and packaging link. They may be packed into cartons, placed on pallets or wrapped with shrink film according to actual needs, so that subsequent transportation and storage can be carried out smoothly.

Common types of yogurt packaging

Plastic cup packaging

Plastic cups are one of the common packaging forms of yogurt. You can purchase a K-cup packaging machine to package yogurt.

Advantages of K-cup packaging machines

(1) Plastic cups have good transparency. Consumers can directly observe the color, texture and state of yogurt through the cup, which greatly enhances the product's visual appeal and credibility. Secondly, plastic cups are relatively light and easy to carry and transport, which is highly consistent with the fast-paced lifestyle and consumption habits of modern consumers.

(2) Plastic cups have a wide variety of choices in shape and capacity, which can well meet the personalized needs of different consumption scenarios and various consumer groups.

(3) Plastic cup packaging has excellent sealing performance, which can effectively prevent yogurt leakage and external contamination, significantly extend the shelf life of the product, and ensure that yogurt always maintains good quality during storage and sales.

Plastic bag packaging

You can use a paste packaging machine to package yogurt. The production cost of plastic bags is relatively low, which makes yogurt packaged in plastic bags have certain competitive advantages in price and can reduce the overall packaging cost of the product.

Advantages of paste packaging machines

(1) Plastic bags have good flexibility and plasticity and can be flexibly adjusted according to the capacity and shape of the product. For example, some long plastic bag packaging is suitable for filling yogurt drinks with strong fluidity, which is convenient for consumers to drink directly.

(2) Plastic bag packaging is relatively weak in barrier properties, and its preservation effect on yogurt may not be as good as plastic cups and paper boxes. Therefore, in general, yogurt packaged in plastic bags needs to be stored and sold in a cold chain environment to ensure that the product quality is not affected and to ensure that the yogurt maintains a good taste and quality within the specified shelf life.

(3) The cost of plastic bag packaging is low, and you can get more profits. Compared with glass bottle and plastic cup packaging, the packaging material cost of plastic bags is relatively low.

Bottled packaging

Bottled yogurt can generally be divided into two types: glass bottle packaging and plastic bottle packaging. You can use a complete filling production line to package yogurt, but this means an increase in budget costs. This solution is more suitable for manufacturers with large budgets and large production sites.

Advantages of filling machine production lines

(1) Glass bottles can be automatically placed by bottle unscramblers, without over-reliance on manual labor. They can completely rely on the automatic work of the machine. From bottle unscrambling to sealing, there is no need for excessive manual intervention, which can save you a lot of labor costs.

(2) Some yogurts with special functions or high-end yogurt products are usually packaged in plastic bottles and paired with carefully designed exquisite bottle labels to enhance the overall grade and attractiveness of the product. In the perception of consumers, bottled yogurt is often associated with high quality and long shelf life, and is more suitable for consumption in fixed places such as homes and restaurants.

Paste packaging machine in yogurt packaging

Paste packaging machines were originally mainly used for the packaging of various paste products, such as toothpaste, ointment, etc.

(1) It can accurately control the filling volume of yogurt. For some yogurt varieties with thicker texture and poor fluidity, such as Greek yogurt and old yogurt, the paste packaging machine can give full play to its advantages.

(2) Ensure that the weight and volume of each product strictly meet the standard requirements, effectively avoiding the problem of inaccurate filling volume. Secondly, the filling head design of the paste packaging machine is highly flexible and can adapt well to containers of different shapes and sizes. Whether it is a common round plastic cup or a square paper box, the paste packaging machine can be used for efficient and accurate filling operations, greatly improving the versatility and adaptability of packaging equipment.

The use of yogurt packaging machines is a major advancement in the dairy packaging machine industry. The introduction of innovative measures such as paste packaging machines has provided a highly efficient solution for yogurt packaging. You can choose a suitable yogurt packaging machine according to your needs.
