Description

Technical Field

[0001] The utility model relates to the technical field of tea refining, in particular to an automatic production line for baking high-quality tea No. 10 from Hubei. Background Art

[0002] E-tea No. 10 is a tea tree variety bred from the natural hybrid offspring of the Enshi moss tea group tea garden through individual plant selection. It has the characteristics of strong cold (drought) resistance, high yield, suitability for machine picking, and suitability for making green tea. Although the tea processed from E-tea No. 10 is of good quality, the tea leaves still have problems such as insufficient compactness when baked after processing. The development of a baking production line suitable for E-tea No. 10 can provide a basis for improving the appearance quality of high-quality green tea and promoting E-tea No. 10 on a large scale.

[0003] The traditional method of making roasted green tea uses a slanted pot or electric frying pan to wither the tea, manual rolling, and charcoal drying. The whole process has a low level of intelligence and automation. Currently, most of the roasted green tea on the market is processed by farmers using existing tea machinery and equipment on the market. The machinery and equipment have a simple structure, and the withering, rolling, and drying processes mostly rely on manual experience, with a low level of standardization.

[0004] Traditional manual or semi-mechanized tea processing methods require a lot of human participation, resulting in low production efficiency and unable to meet the market's rapidly growing demand for high-quality tea. Manual operations often make it difficult to accurately control each link of tea processing, such as withering temperature, rolling strength, drying time, etc. Changes in these factors will directly affect the final quality of the tea, resulting in unstable quality.

[0005] The existing production lines do not perform screening and cooling after withering of green tea during the processing of roasted green tea, which seriously affects the quality and color of the tea. The tea is prone to problems such as insufficient or excessive withering, low rate of rolling into strips or high rate of broken tea, insufficient aroma during the drying process, and uneven drying, which seriously restricts the development of roasted green tea.

DETAILED DESCRIPTION

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0030] like Figure 1 As shown, the high-quality tea drying automatic production line of E-tea No. 10 of the practical design includes a continuously arranged tea withering unit, a tea air selection unit, a tea rolling unit, a drying and cooling unit and a tea collection table 100;

[0031] The tea leaf fixing unit comprises an electromagnetic tea leaf fixing machine 1, and a feeding conveyor 2 and a cooling conveyor 3 respectively arranged at a feeding port and a feeding port of the electromagnetic tea leaf fixing machine 1;

[0032] The tea leaf air selection unit comprises an air selection machine 4 arranged at the unloading end of the cooling conveyor 3, and an air selection conveyor 5 arranged at the unloading end of the air selection machine 4;

[0033] The tea rolling machine group includes a tea rolling machine 6, and a weighing and distributing machine 7 for collecting tea leaves from the unloading end of the air selection conveyor 5 and weighing and evenly conveying the tea leaves to the tea rolling machine 6;

[0034] The drying and cooling unit comprises a tea chain plate drying machine 8, a tea electromagnetic frying and drying machine 9, a tea cooling and rehumidifying machine 10, and a drying and cooling conveyor 11 for drying, cooling and conveying the tea.

[0035] The tea leaves are fed into the electromagnetic tea-killing machine 1 through the feeding conveyor 2 for rapid high-temperature tea-killing to destroy the enzyme activity in the tea leaves and keep the tea leaves green. The tea leaves after killing are transported to the air separator 4 through the cooling conveyor 3 to remove impurities and unqualified tea leaves fragments through air separation.

[0036] The wind-selected tea leaves are then sent to a weighing and distributing machine 7 by a wind-selection conveyor 5, which is responsible for collecting and evenly weighing the tea leaves, and then sent to a tea rolling machine 6 for rolling, so that the tea leaves are rolled into strips, thereby increasing the aroma and flavor of the tea leaves.

[0037] The rolled tea leaves enter the drying and cooling unit, where they are first dried by the tea chain plate dryer 8 to remove excess water. Then, the tea leaves enter the tea electromagnetic frying and drying machine 9 for further frying and drying to enhance the aroma and taste of the tea leaves. Finally, the tea leaves enter the tea cooling and rehumidification machine 10 for cooling and rehumidification to achieve the ideal finished product state.

[0038] During the whole drying and cooling process, the tea leaves are transported by the drying and cooling conveyor 11 to ensure that the tea leaves are smoothly transferred between the devices. Finally, the finished tea leaves are collected on the tea leaves collection platform 100 to complete the whole automated production process.

[0039] This production line achieves high efficiency, stability and consistency in tea processing by precisely controlling the process parameters of each process and the coordinated work of automated equipment, ensuring the high quality of E-Cha No. 10 roasted green tea.

[0040] As an implementation mode, the electromagnetic tea-fixing machine 1 adopts electromagnetic heating as the heating method. The drum electromagnetic heating coil is composed of three sections, and the coil is fixedly installed. The tea-fixing temperature is controlled by controlling the current of the heating coil.

[0041] The withering machine drum is made of martensitic stainless steel, with a diameter of 1600mm and a drum length of 4800mm. There are 5 spiral guide vanes in the drum, and the length of the spiral guide vanes between the feeding end and the discharging end is 200mm. The spiral guide vane angles between the feeding end and the discharging end are 45°, and the spiral guide vane angle of the withering section is 10°. The PLC controller controls the frequency of the withering machine motor to control the drum speed; the withering machine intelligent temperature meter is installed on the inner drum of each heating coil; the withering machine discharge port is located directly above the conveyor

[0042] As an implementation mode, the tea rolling machines 6 are arranged in two groups, and each group of tea rolling machines 6 is arranged in multiple groups continuously.

[0043] Specifically, each group of tea rolling machines has 7 units connected in parallel, for a total of 14 units.

[0044] A weighing and distributing machine 7 is installed above the tea rolling machine 6. The weighing and distributing machine 7 is installed on the frame of the tea rolling machine 6 and can move left and right. A tea outlet is installed at each end of the weighing and distributing machine 7. The lower part of the tea outlet corresponds to the kneading barrel of the tea rolling machine 6. The upper part of the weighing and distributing machine 7 corresponds to the conveying port of the conveyor. The tea leaves are transported to the weighing and distributing machine 7 by the air selection conveyor 5. The PLC controller controls the movement of the weighing and distributing machine 7 to the designated kneading barrel for unloading.

[0045] The 14 tea rolling machines 6 work independently. The outer diameter of the tea rolling barrel of the tea rolling machine 6 is 65 cm, the speed of the rolling machine is 45-55 r / min, 18 ribs are evenly distributed on the rolling plate, the concavity of the rolling plate is 7°, and the speed of the rolling barrel is controlled by controlling the frequency of the rolling machine motor; the movement of the rolling barrel cover of the rolling machine group is controlled by a PLC controller to realize the pressurization and loosening process; the two rows of rolling machines have a corresponding flat conveyor below the discharge port.

[0046] Specifically, the unloading end of the tea rolling machine 6 in the same group is equipped with a unloading conveyor belt 6.1 for the tea rolling machine group.

[0047] As an implementation method, the drying and cooling unit adopts a tea chain plate drying machine 8, a tea electromagnetic frying and drying machine 9, a tea cooling and rehumidification machine 10, and a tea chain plate re-drying machine 12 arranged at the unloading end of the tea cooling and rehumidification machine 10.

[0048] The effective drying area of ​​the chain-type dryer 8 and the tea chain-type re-drying machine 12 is 30m2, the main engine power is 1.5KW, the number of drying layers of the drying oven is 6, the transmission method is chain transmission, the heating method is hot air heating, the working width of the impeller is 120cm, and the operating speed is 2-5r / min; the intelligent temperature meter of the dryer is installed in the middle position of each layer, and the PLC controller controls the dryer motor frequency to control the chain speed, and the dryer cooling and rehumidification machines are connected by a conveyor.

[0049] Ten fans are evenly installed above the tea cooling and rehumidifying machine 10, with an effective cooling area of ​​50m2, a main engine power of 3KW, three layers of drying leaves in the drying oven, a chain drive, and a PLC controller controls the frequency of the cooling machine motor to control the chain speed.

[0050] As a supplement, the unloading end of the tea chain plate dryer 8 is also equipped with a vibrating conveying and removing dust trough 8.1, and the trough body of the vibrating conveying and removing dust trough 8.1 is evenly punched with circular holes with a diameter of 0.2-0.3 cm.

[0051] The main function of the vibration conveying dust removal tank 8.1 is to separate the fine dust, tea crumbs and other impurities in the tea leaves by vibration after the tea leaves are dried. These impurities may be generated in the previous processes such as picking, withering, rolling, etc. If they are not removed in time, they will affect the overall quality and taste of the tea leaves.

[0052] Specifically, when the tea leaves are dried in the chain plate dryer 8 and fall into the vibrating conveying dust removal trough 8.1, the vibration of the trough body causes the tea leaves to form a certain throwing motion in the trough, thereby causing relative motion between the tea leaves and the impurities. Since the impurities such as dust and tea scraps are small in size and light in weight, they are more easily thrown away from the main body of the tea leaves during the vibration process and fall into the collection device below through the circular holes (usually with a diameter of 0.2-0.3 cm) uniformly punched on the trough body.

[0053] The tea leaves after the powder removal treatment will continue to be transported along the vibration conveying powder removal trough 8.1 to the next process, such as the tea electromagnetic frying and drying machine 9 for further processing. In this way, the powder removal treatment of the vibration conveying powder removal trough 8.1 can significantly improve the purity and consistency of the tea leaves, laying a solid foundation for subsequent processing and the quality of the final product.

[0054] As an implementation mode, the feeding conveyor 2, the cooling conveyor 3, the weighing and distributing machine 7, and the drying and cooling conveyor 11 are all assembled from one or more of a horizontal conveyor, a vertical conveyor, and a tea elevator.

[0055] In the E-tea No. 10 high-quality green tea automatic production line, the design principles of key conveying equipment such as the feeding conveyor 2, cooling conveyor 3, weighing and distributing machine 7 and drying and cooling conveyor 11 reflect the pursuit of high efficiency and flexibility in material transfer in the tea processing process. These equipments jointly construct a complex and orderly tea conveying system by adopting one or more assembly methods of horizontal conveyors, vertical conveyors and tea elevators.

[0056] According to the specific layout of the production site and the spatial relationship between the processes, the appropriate conveyor type is selected for assembly. The horizontal conveyor is mainly used for continuous conveying of tea on the same horizontal plane to ensure that the tea can smoothly and stably enter the next process from one process. The vertical conveyor and tea elevator are used to deal with the height difference and realize the vertical transportation of tea between different heights to meet the space requirements in the production process.

[0057] Secondly, by rationally arranging and regulating the conveyor's operating parameters, such as conveying speed, inclination angle, etc., ensure that the tea leaves maintain a stable posture and proper movement during transportation. This helps reduce damage and breakage of the tea leaves during transportation, while improving transportation efficiency.

[0058] Finally, through precise docking and coordinated control between the various conveying equipment, the seamless transfer of tea leaves throughout the entire production line is achieved. Whether from the withering unit to the winnowing unit, or from the rolling unit to the drying and cooling unit, the tea leaves can be accurately transported to the designated location and maintain continuity and consistency between each process.
