With the continuous inheritance of tea culture and the continuous expansion of market demand, the OEM production of teabags has gradually been loved by consumers as a convenient and fashionable way to drink tea. In this production process, strict quality control and scientific process flow are crucial. Below, we will analyze the OEM production process of tea bags in depth.
Chinese medicine crushed
First of all, the first step in the production process is the crushing of traditional Chinese medicine. At this stage, the Chinese herbs in the raw materials need to be ground by professional crushing equipment to ensure the uniformity and fineness of the particles. The key to this step is to preserve the natural aroma of the raw material and the active ingredients, laying the foundation for subsequent production.
Sterilization
After the Chinese medicine is crushed, the raw materials need to be sterilized to ensure the hygiene and quality of the tea and raw materials. This step uses high temperature, high pressure or other sterilization methods to effectively kill potentially harmful microorganisms and ensure the hygiene and safety of tea.
Weigh and mix
The next step is to weigh and mix the raw materials precisely. At this stage, the various ingredients are blended according to the recipe ratio to ensure that the taste and aroma of each tea bag can meet the standard. This step requires precise control of the instrument to ensure that the tea produced is of consistent quality.
Granulation and whole granulation
Subsequently, the mixed raw materials need to go through the process of granulation and granulation. Granulation is to make the mixed materials into granules suitable for tea bags through professional equipment, while whole grains are to retain the natural form of the raw materials and make the tea more ornamental and tasteful.
Tumble dry
Drying is a crucial step in the production of tea bags. By precisely controlling the temperature and humidity, the water in the tea leaves is evaporated and the tea leaves are kept dry. This not only helps to maintain the freshness of the tea but also extends the shelf life of the tea.
Fill the tea bag
The dried tea leaves are precisely packed into tea bags. The material and process of the tea bag also need to be carefully selected to ensure that the tea leaves can fully unfold during use, releasing the maximum aroma and taste.
Pack a small foil bag
The final step is to seal the small foil pouch containing the tea bag. The aluminum foil pouch has excellent barrier properties, which can prevent the influence of external moisture, light and oxygen on the tea leaves, ensuring the freshness and quality of the tea leaves. At the same time, it is also convenient for consumers to carry and keep.
Through the above series of technological processes, the OEM production of tea bags can be carried out efficiently and standardized. Strict quality control and scientific technological process ensure that each bag of tea can meet consumers' pursuit of taste and aroma, laying a solid foundation for the sustainable development of the tea bag industry.
