Description

Technical Field

[0001] The present application relates to the technical field of tea processing, and more specifically, to a bamboo tube tea preparation process. Background Art

[0002] As people's quality of life improves, the demand for tea products has become diverse, and bamboo tube tea is one of the varieties. In related technologies, bamboo tube tea is usually packaged and stored by putting tea leaves into bamboo tubes. Through long-term storage, the flavor of the bamboo tube itself penetrates into the tea leaves, giving the tea leaves an additional bamboo aroma.

[0003] By using the above-mentioned related technologies, although the tea leaves are infiltrated with the fragrance of bamboo, the taste is relatively light, and the fragrance of bamboo is not largely infiltrated into the tea leaves, so that the taste and fragrance of bamboo tube tea are insufficient. Summary of the invention

[0004] In order to solve the problem that the bamboo used in bamboo tube tea is not cleaned well by using related technologies, resulting in insufficient taste and fragrance of the bamboo tube tea, the present application provides a bamboo tube tea preparation process.

[0005] A bamboo tube tea preparation process comprises the following steps:

[0006] Step S1, prepare bamboo, cut the bamboo into bamboo tubes, punch holes in the uppermost and lowermost bamboo interlayers of the bamboo tube to form openings, and open all the bamboo interlayers inside the bamboo tube, and wash the bamboo tube for later use;

[0007] Step S2, loading tea into the bamboo tube through the opening of the bamboo tube;

[0008] Step S3, baking, using a tea baking device to bake the bamboo tube at a temperature of 120-200° C. for 30-60 minutes;

[0009] Step S4, drying, putting the baked tea leaves into a drying room for drying, the drying temperature is 38-45° C., and the drying time is 1-2 days to obtain the finished bamboo tube tea.

[0010] Preferably, the bamboo used to make the bamboo tube is pure natural freshly cut bamboo, and is used within two days after being cut. The length of the bamboo tube is 50-80 cm, and the inner diameter is greater than 6 cm.

[0011] Preferably, the tea leaves are put into bamboo tubes for baking after being withered and rolled.

[0012] Preferably, the tea leaves are one of green tea, oolong tea, black tea, white tea and Pu'er tea.

[0013] Preferably, in step S2, fresh petals are also placed in the bamboo tube.

[0014] Preferably, the tea baking device in step S3 includes a frame, a rotating drive mechanism, and an open flame baking oven, wherein the rotating drive mechanism is used to fix the bamboo tube and drive the bamboo tube to rotate, and the open flame baking oven is fixed on the frame and is located at a position corresponding to the peripheral wall of the bamboo tube to emit an open flame to heat the bamboo tube.

[0015] Preferably, the rotation driving mechanism includes a motor, a first rotating shaft, a second rotating shaft, a movable shaft, a linear bushing, and a locking piece, the first rotating shaft is rotatably connected to the frame, the linear bushing is fixed on the frame, the movable shaft movably penetrates into the inner hole of the linear bushing, the second rotating shaft is rotatably connected to the movable shaft, and the rotation center of the second rotating shaft is on the same straight line as the rotation center of the first rotating shaft, the locking piece is arranged on the linear bushing for locking and fixing the movable shaft or releasing the locking and fixing of the movable shaft, the first rotating shaft is provided with a first pressing block at one end facing the second rotating shaft, and the second rotating shaft is provided with a second pressing block at one end facing the first rotating shaft, the bamboo tube is fixed by the first pressing block pressing one end of the bamboo tube and closing the opening of the end and the second pressing block pressing the other end of the bamboo tube and closing the opening of the end, the motor is fixed to the frame and connected to the first rotating shaft to drive the first rotating shaft to rotate.

[0016] Preferably, the rotation speed of the motor is 10-20 rpm.

[0017] The beneficial technical effects of this application are:

[0018] 1. Since fresh bamboo contains bamboo sap, when the bamboo tube filled with tea leaves is baked, the high temperature causes the bamboo sap contained in the bamboo tube to flow out from the inner wall and evaporate into bamboo sap steam. The bamboo sap steam is then evenly blown onto the tea leaves in the tube and absorbed by the tea leaves with super adsorption capacity. The fragrance of bamboo penetrates into the tea leaves to a greater extent, and the resulting bamboo tube tea has a rich bamboo fragrance.

[0019] 2. Fix the bamboo tube by rotating the driving mechanism and then drive the bamboo tube to rotate, so that the tea leaves are turned inside the bamboo tube. The bamboo tube is heated by an open flame in an open flame oven to bake the tea leaves. The tea leaves are turned inside the bamboo tube to achieve uniform baking, which reduces manual turning of the tea leaves and reduces the labor intensity of the staff.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] A bamboo tube tea preparation process comprises the following steps:

[0024] Step S1, preparing bamboo, using pure natural freshly cut bamboo, the bamboo is made into bamboo tubes within two days and used, the length of the bamboo tube is in the range of 50-80 cm, and the inner diameter is greater than 6 cm, the bamboo interlayers at the top and bottom of the bamboo tube are punched to form openings, and the bamboo interlayers inside the bamboo tube are all opened, and the bamboo tube is washed and set aside;

[0025] Step S2, filling tea, mixing tea leaves and fresh flower petals and filling the tea leaves into the bamboo tube through the opening of the bamboo tube, wherein the tea leaves occupy two-thirds of the internal volume of the bamboo tube, and the fresh flower petals are edible fresh flower petals, such as rose, marigold, jasmine, etc.;

[0026] Step S3, baking, using a tea baking device to bake the bamboo tube, so that the bamboo tube is baked at a temperature of 120° C. for 60 minutes. During this process, the high temperature causes the bamboo sap contained in the bamboo tube to flow out from the inner wall and evaporate into bamboo sap steam, and then the bamboo sap steam is evenly blown onto the tea leaves in the tube and absorbed by the tea leaves with super adsorption capacity. The fragrance of the bamboo penetrates into the tea leaves to a greater extent, and the fragrance of the fresh petals can also penetrate into the tea leaves, making the taste and aroma of the tea leaves richer;
