Spring roll production line: a modern manufacturing journey of traditional food.

Spring rolls, a long-standing traditional Chinese festival food, have now entered thousands of households through modern production lines, and even crossed the ocean to become a delicacy on the international table. Today, let us walk into the spring roll production line together to see how this traditional food has been rejuvenated with the help of modern technology!

1. Filling production: a fusion of tradition and modernity

Raw material preparation: Filling is the soul of spring rolls. Traditional spring roll fillings include vegetarian food such as bean paste and vegetables, as well as non-vegetarian food with meat and various vegetables. Modern production lines pay more attention to the diversity and standardization of ingredients. Bamboo shoots, carrots, pork and other raw materials are carefully selected and cut to ensure that each filling is delicious and nutritionally balanced.

Stirring the filling: Put the cut ingredients into the blender, add appropriate amount of seasoning and sesame oil, and stir for a certain period of time, and the filling is ready. In this process, the machine can accurately control the mixing time and temperature to ensure the taste and quality of the filling.

2. Spring roll wrapper production: automation and efficiency

Batter preparation: Flour and water are needed to make spring roll wrappers. Modern production lines use precise proportioning and mixing to prepare the batter into a state suitable for baking.

Baking spring roll wrappers: The batter is transported to the machine through negative pressure in the pipeline, and the spring roll wrappers are made after high-temperature baking. In this process, the machine can accurately control the baking temperature and time to ensure the taste and toughness of the spring roll wrappers.

3. Spring roll forming: speed and precision

Filling distribution: The prepared fillings are evenly distributed to each spring roll wrapper through a CNC filling machine. The machine can accurately control the weight and distribution of the fillings to ensure that each spring roll is full and beautiful.

Rolling and forming: The spring roll wrappers with the fillings distributed are passed through the folding and forming part, and the fillings are wrapped with the spring roll wrappers on both sides, and then the spring rolls are rolled and formed through the rolling and friction wrapping part. In this process, the machine can run at high speed and can make dozens of spring rolls per minute.

4. High-temperature frying and cooling

Frying: The rolled spring rolls need to be put into the fryer and fried at an oil temperature of about 180℃ for about 3 minutes. During this process, the spring rolls become crispy and delicious, and the aroma is overflowing.

Cooling and quality inspection: The fried spring rolls need to be manually inspected to ensure that there are no exposed fillings or poor-looking products. Then, the spring rolls are quickly cooled down and packed into boxes.

5. Packaging and storage

Packaging: The cooled spring rolls are sent to the packaging machine, and after heat sealing and other processes, they are neatly packaged in plastic boxes or plastic bags.

Storage: The packaged spring rolls are sent to the low-temperature freezer for storage. In an environment below -18℃, spring rolls can maintain their taste and quality for up to several months.

Through modern production lines, spring rolls, a traditional delicacy, can be produced efficiently and in a standardized manner. It has successfully expanded to the international market. Whether it is a family gathering or a delicacy on the international table, spring rolls have won people's love with their unique taste and flavor. Let us look forward to spring rolls continuing to shine more brightly in the future!
