Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and in particular to equipment and technology for mixed processing of Rabdosia rubescens and Pu'er tea. Background Art

[0002] In the tea processing sector, blending and roasting different tea types to develop new tea products has become an important way to expand the tea market and meet diverse consumer demands. For example, blending Rabdosia rubescens and Pu'er tea offers a promising market opportunity, combining the heat-clearing and throat-relieving properties of Rabdosia rubescens with the rich, flavorful flavor of Pu'er tea.

[0003] However, the current tea blending process is often carried out manually. During manual operation, operators must manually weigh Rabdosia rubescens and Pu'er tea according to a specific ratio, place them in a container, and then perform preliminary mixing by stirring. Finally, the mixture is transferred to a tea-roasting machine for roasting. This method not only has a low degree of automation, making it difficult to improve production efficiency and meet the needs of large-scale production, but also requires long periods of manual operation, resulting in extremely high labor intensity and easily leading to operator fatigue, which in turn affects the continuity and stability of production. Furthermore, manual operation is affected by individual differences, making it difficult to accurately control the tea blending ratio and mixing uniformity, resulting in uneven product quality and difficulty in ensuring product standardization and consistency. Furthermore, manual operation requires a significant amount of labor, increasing production costs and reducing the company's market competitiveness.

[0024] The present invention will be described clearly and completely below with reference to the accompanying drawings and embodiments:

[0025] like Figures 1 to 4As shown, the equipment for mixed processing of wintercress and Pu'er tea described in the present invention comprises a feed box 1, which is divided into two storage cavities 2 for storing wintercress tea and Pu'er tea respectively; a mixing bin 3 is provided at the bottom of the feed box 1, and a mixing paddle driven by a motor is provided in the mixing bin 3, and a valve is provided at the bottom of each storage cavity 2, which can be an electric butterfly valve, a pneumatic gate valve or an electric regulating valve, which can be flexibly selected according to the actual working conditions; a conveying mechanism 4 is provided at the bottom of the mixing bin 3, and the outlet of the conveying mechanism 4 is arranged at the inlet of a tea frying machine 5, and a material receiving mechanism connected to the inside is provided on the tea frying machine 5, for receiving the mixed tea leaves conveyed by the conveying mechanism 4 and conveying the tea leaves into the tea frying machine 5; the tea frying machine 5 of the present invention is a drum-type tea frying machine 5 in the prior art. The present invention provides a feed box 1 divided into two storage cavities 2, which can store wintergreen and Pu'er tea respectively. The valve at the bottom of the storage cavity 2 can accurately control the amount of the two types of tea entering the mixing bin 3, effectively solving the problem that it is difficult to accurately control the tea ratio through manual operation, and greatly improving the standardization and consistency of the product; in addition, the motor-driven mixing paddle in the mixing bin 3 realizes automated mixing. Compared with manual stirring, the mixing efficiency is greatly improved, the mixing uniformity is also guaranteed, and the fatigue of the operator caused by long-term and high-intensity labor is avoided, thereby enhancing the continuity and stability of production.

[0026] In the present invention, the feed box 1, the mixing bin 3 and the conveying mechanism 4 are all arranged above the tea roasting machine 5; a group of supporting poles 6 are provided at the front and rear ends of the conveying mechanism 4 and the tea roasting machine 5, and a plurality of cross braces 7 are provided between each group of two supporting poles 6 along their height direction, which can not only ensure the stability of the entire equipment structure, but also assist the staff to climb up to inspect and maintain the upper mechanism.

[0027] Furthermore, a door panel 8 is hingedly connected to the front end of the tea roasting machine 5 to seal the front entrance of the machine 5. Opening the door panel 8 facilitates the subsequent discharge of tea leaves after roasting. A material receiving mechanism is provided on the door panel 8 to enable the addition of tea leaves without opening the door panel 8, thereby reducing heat loss within the tea roasting machine 5 and improving roasting efficiency. Specifically, the material receiving mechanism includes baffles 9 arranged on either side of the door panel 8, with a sealing plate 10 hingedly connected between the two baffles 9. The door panel 8 corresponding to the sealing plate 10 has a feed inlet. By opening the sealing plate 10, the mixed tea material discharged from the upper conveying mechanism 4 can be received, enabling the addition of tea leaves into the tea roasting machine 5. After the addition of tea leaves is completed, the sealing plate 10 can be closed to reduce heat loss. Preferably, the outer side of the baffle 9 is in the shape of a right triangle, with the right-angled side connected to the door panel 8. A support block is provided on the inner side of the baffle 9. During unloading, the sealing plate 10 opens and abuts against the support block to form an inclined guide channel, which facilitates the smooth entry of the mixed tea material into the tea roasting machine 5. In addition, a pressure plate 11 is movably provided on the door panel 8 via a hinge shaft. The pressure plate 11 can be pressed against the sealing plate 10 by rotating the hinge shaft to achieve the purpose of positioning the sealing plate 10. A cylinder or electric push rod can also be hingedly provided on the door panel 8, and the telescopic end of the cylinder or electric push rod is hinged to the sealing plate 10 via a hinge seat. This can further improve the automation performance of the entire equipment, reduce the frequency of manual intervention, and reduce labor costs.

[0028] Furthermore, the conveying mechanism 4 is a screw conveyor, which facilitates the smooth conveying of the mixed tea raw materials to the material receiving mechanism.

A material receiving box 14 is provided on the screw conveyor housing below the slag discharge port 13 for receiving the sieved residues and debris. The material receiving box 14 is detachably provided on the screw conveyor housing to facilitate the cleaning of the residues and debris. A filter 15 is provided between the slag discharge chamber 12 and the conveying blades 16. The mesh size of the filter 15 is smaller than the size of the tea raw materials. The filter 15 is provided to timely filter out the debris entrained in the tea leaves during the process of conveying the tea leaves to the tea frying machine 5, thereby ensuring the quality of the tea frying.

[0029] In addition, bristles 17 are provided on the conveying blades 16. In the initial state, the bristles 17 contact the surface of the filter screen 15. This configuration prevents the filter screen 15 from being clogged, thereby ensuring screening quality. In the present invention, two slag discharge ports 13 are provided, and a guide plate 18 is provided in the slag discharge chamber 12. The longitudinal cross-section of the guide plate 18 is an inverted V-shaped structure. Both sides of the guide plate 18 extend to the slag discharge port 13. The screened residue flows smoothly from the slag discharge port 13 through the inclined surface of the guide plate 18 into the material receiving box 14, reducing the probability of blockage.
