Tieguanyin tea bag production line sets up with 8 sets of vacuum tea bag packing machine + 1 automatic filling machine:

The packaging process for Tieguanyin tea bag is mainly: Refined finished tea (Sorting and cleaning) → Small tea bag packing (Vacuum) → Boxing (Canning)→ Cartonging → shipping.

The production line of Tieguanyin adopts mature equipment and technology, such as color sorter, drying machine for baking, tea removal of impurities and dust, automatic control system, automatic packaging machinery, etc.

Tieguanyin tea bag packaging line & production line has the following characteristics:

1. Optimizing roller swing and roller fixed-point logic control mode：
In view of the problem that the directional rotation of the original drum leveling machine and the degree of uniformity of the tea leaves in the drum are limited, the newly added drum swing and drum fixed-point logic control mode can make the raw materials more evenly blended, and reduce the tea breakage rate and equipment performance and consumption.

2. Electrostatic cleaning method:
The original electrostatic impurity removal equipment uses high-voltage static electricity, but because high-voltage static electricity is easy to generate electric sparks, it is not suitable for tea refining. Replace high-voltage static electricity with frictional static electricity, and use the principle of frictional electrification to make the tea leaves jump forward along the inclined vibrating screen surface under the roller. After 6 times of electrostatic adsorption, the hair, fiber and dust in the tea can be basically removed. And other impurities are removed.

3. Tea color sorting method:
Using infrared photoelectric technology, according to the difference in the optical characteristics of the material, the infrared photoelectric technology is used to automatically sort the non-tea foreign objects such as foreign colors and shapes in the tea raw materials; quantitatively supply raw materials through the belt, and pass 6 groups of each during the transmission process. A group of 64 channels and 2 InGaAs (indium gallium arsenide) infrared cameras are used for double-sided identification to accurately identify defective products, and then a new 4 mm small-diameter high-speed nozzle (1500 times/second) is used to inject compressed air to remove defective products. Process innovation applies three-stage multiple sorting to obtain high-quality finished products.

4. Metal detection and impurity removal methods:
Using the latest generation of digital signal processing technology and German automatic filtering technology, tea raw materials are automatically detected and eliminated by electromagnetic wave induction and iron (φ≥0.8 mm), stainless steel (φ≥1.5 mm), copper (φ ≥1.2 mm) and other metal substances; the metal detector is installed at the end of the process to perform the last food safety inspection function to prevent the outflow of tea mixed with metal substances, so as to meet the SC food safety production requirements.

5. Tea powder recovery and purification method:
The process of tea refining is easy to produce powder. The process innovation design has 71 purification points, including a sealed cover of 29.5 m2, 12 sets (10 sets of 1.5 kw fans, 40 sets of 5 μm polyester) dust collectors, and a new dust-proof sealing device for the whole line. 304 stainless steel closed design , Realize that the refining process covers the whole line of negative pressure working environment, effectively recycle tea powder and prevent foreign matter from falling into it.

6. Configure intelligent distributed control system:
The control system adopts Siemens PLC as the lower computer to directly control the operation of the equipment; the on-site touch screen is used to realize the display and setting of data, monitor the status of the equipment, maintain the control and alarm, and has strong operability; The machine adopts industrial computer, and configures and integrates the Siemens lower computer to realize the continuous control and process monitoring of the production line; the project newly configures the mobile terminal control system and distributes it to all mobile terminals connected to the network through industrial wireless routers to realize "one Machine full control" function.

Tieguanyin automated small packaging production line technology integration:

Through the innovation and upgrading of the key technologies of the automated Tieguanyin bulk tea refining production line and small packaging line, and the adoption of tea automation and comprehensive flexible packaging technology, the entire process from raw material pretreatment to packaging and shipment is automated, clean, and standardized, which can improve production. The efficiency is more than 150%, the small packaging capacity of each production line can reach 900 boxes/hour, the product excellent rate is more than 99.5%, the purification rate of tea powder in the workshop can reach more than 99.5%, and the energy consumption can be saved by more than 30%.

The industrialization and application of the results embodies the wisdom and experience of tea people, and is a fruitful achievement of tea science and technology and practical experience. Faced with the bottleneck problems of semi-automated tea equipment in the main oolong tea production area, efficiency and quality can not keep up, the implementation and promotion of the results have realized the technological innovation of modern, large-scale, and intelligent processing of oolong tea, and effectively improved the high-quality rate of products.

Inner and outer tea bag vacuum packing machine for tieguanyin tea is a new attempt in quality control of tea to ensure that the product go into production with high quality, and to innovatively introduce robots in the field of tea packaging. It not only saves labor costs, but also reduces quality control problems caused by human factors, which greatly improve the economic benefits of the tea industry.
