Description

Technical Field

[0001] The utility model relates to the technical field of rolling machines, in particular to a novel black tea rolling machine. Background Art

[0002] In the field of tea processing technology, rolling of dark tea is an extremely critical process. Its purpose is to break the tea cells and let the tea juice seep out through rolling, so as to shape the appearance of the tea leaves and promote the transformation of the substances contained therein, thereby affecting the quality and taste of the dark tea.

[0003] The traditional black tea rolling machine is mainly composed of a rolling drum, a rolling plate and other components. The rolling drum is driven by a power device to roll the tea leaves placed on the rolling plate. However, there are many problems in the actual use of the existing rolling machine. For example, during the rolling process, tea leaves tend to accumulate in some corners or gaps of the rolling plate, especially around some rolling plate components with complex structures, such as structures such as conduction tubes, where tea leaves are often stuck and difficult to clean. This will not only cause tea residues and affect the sanitation of the equipment, but also, as the amount of tea residue increases, it will interfere with the normal rolling operation, reduce production efficiency, and require frequent shutdowns for manual cleaning, which seriously affects the continuity of production. In addition, since the tea leaves are not turned sufficiently during the rolling process, uneven rolling is likely to occur, resulting in uneven release of substances contained in the tea leaves, which ultimately greatly reduces the taste and flavor of the black tea.

[0004] Therefore, we propose a new black tea rolling machine. Utility Model Content

[0014] Beneficial effects

[0015] The novel black tea rubbing and twisting machine has the following beneficial effects:

[0016] 1. The novel black tea rubbing and twisting machine has multiple advantages due to the unique jet assembly design. The airflow generated by the gas pump is transmitted to the transmission pipe through the gas guide pipe and sprayed out through the nozzles at the angles of the lotus pieces. On the one hand, during the rubbing and twisting operation, the tea leaves can be effectively prevented from being left in the transmission pipe, the difficulty and frequency of manual cleaning are reduced, the cleaning convenience and production continuity of the equipment are improved; on the other hand, the jetting can achieve good turning effect when the tea leaves on the transmission pipe are rubbed and twisted between the lotus table and the bottom of the rubbing cylinder, so that the tea leaves are more fully contacted with the rubbing and twisting parts, the uniformity and efficiency of rubbing and twisting are further improved, which is helpful for the uniform release of the contents in the tea leaves and optimizes the taste and flavor of the black tea.

[0017] 2.The new type of black tea rolling machine, through the cooperation of linkage rod assembly and driving motor, makes the rolling cylinder closely fit the inner disc edge of lotus platform and stably move, which ensures that the tea can be fully and uniformly rolled and crushed between the adjacent ends of the lotus platform and the rolling cylinder, guarantees the quality and effect of tea rolling, improves the overall quality of black tea processing, and lays a solid foundation for producing high-quality black tea products.

[0018] 3.The new type of black tea rolling machine, the extrusion mechanism in the rolling cylinder plays an important role. The servo motor controls the horizontal rod to drive the lower pressing disc to move up and down, which can repeatedly press the tea in the rolling cylinder. This operation can make the tea fall more smoothly into the lotus platform for rolling work, avoid the accumulation or blockage of tea in the rolling cylinder, ensure the orderly progress of the rolling process, and also make the stress of tea more uniform in the whole rolling process, which helps to improve the standardization degree and product consistency of black tea rolling.

[0019] 4.The new type of black tea rolling machine, the setting of the protective bottom disc provides protection for the stable operation and maintenance of the equipment. The protective mesh cover is fixed with the bottom of the processing table through the fixing bolt, which effectively supports and protects the air jet assembly in the motor slot from damage caused by foreign matter entering the motor slot, prolongs the service life of the air jet assembly. When the equipment stops running, the protective bottom disc can be easily removed for maintenance and maintenance of the air jet assembly in the motor slot, which reduces the maintenance difficulty and cost of the equipment, improves the maintainability and overall reliability of the equipment.
