Problems solved by technology

The development trend of kneading machine is continuous and automatic. Since the current production can only be a stand-alone operation, the difficulty of manufacturing a continuous kneading machine is that the tea leaves have to bear different forces in the machine, and the forces borne by the leaves should work through the leaf clusters. , instead of kneading a certain part of the cavity to work on a single leaf, otherwise a large amount of broken tea will be produced

Embodiment 1

[0016] An oxygen-increasing rolling method suitable for tea processing, especially for black tea shaping operations, provided by the following steps:

[0017] 1. Design figure 1 The device: the device is mainly composed of oxygen generator (oxygen tank) 1, plastic connecting pipe 2, connecting head 3, stainless steel pipe 4, kneading cover 5, kneading barrel 6, kneading plate 7, etc., plastic connecting pipe 2 One end is connected to the oxygen generator (oxygen tank) 1, and the other end is connected to the connector 3. The connector 3 is located on the kneading cover 5 and directly embedded on the kneading cover 5 (see figure 2 , image 3 ), the other end of the connector 3 is connected to the stainless steel pipe 4, the other end of the stainless steel pipe 4 is closed, and the stainless steel pipe 4 is fixed on the back of the kneading cover 5 by glass glue (see Figure 4 ), several small holes with a diameter of 1mm are set on the pipe wall of the stainless steel pipe ...

Embodiment 2

[0020] Referring to Example 1 ( Figure 1-Figure 4 ), first insert the connector 3 on the kneading cover 5 of the traditional 55-type kneading machine, set the stainless steel pipe 4 on the back of the kneading cover 5 through glass glue, the stainless steel pipe 4 is closely connected with the connector 3, and the stainless steel pipe 4 is provided with small holes (not shown in the figure), the other end of the connector 3 is connected to the plastic pipe 2, and the plastic pipe 2 is connected to the oxygen generator (oxygen cylinder) 1. During operation, put the finished product into the kneading barrel 6 according to the traditional kneading process, rotate the kneading machine handle to cover the kneading cover 5, then turn on the switch of the oxygen generator 1, control the air valve so that the oxygen flux is about 0.1MPa, and then Start the kneading device, the oxygen is input into the stainless steel pipe 4 through the plastic connecting pipe 2, and then output throu...

Embodiment 3

[0023]

[0024] Note: The raw materials of the three treatment samples are the tender fresh leaves of Cuifeng variety with 1 bud and 1 leaf. After withering to the same degree, different rolling techniques are used. drying job.

[0025] From the sensory evaluation results of tea samples with different treatments in the examples, it can be seen that the sensory quality of the tea samples after the oxygen-increased rolling operation is significantly improved compared with that of the tea samples without oxygen-increased rolling, especially in factors such as soup color, leaf bottom and aroma. By adding oxygen during the rolling process, the physiological activity of the product can be kept longer, the material transformation is more uniform and thorough, the soup color becomes brighter, and the generation of green streaks and dull taste can be avoided at the same time.

Abstract

The invention provides an oxygenation rolling method for black tea processing. A rolling oxygenation device comprising an oxygen generator, a plastic connecting pipeline, a connecting head, a stainless steel pipeline, a rolling cover, a rolling barrel, a rolling disc and the like is designed first, wherein the rolling cover, the rolling barrel and the rolling disc belong to major components of a rolling machine; the connecting head is embedded into the rolling cover and connected with the plastic connecting pipeline and the stainless steel pipeline; small holes are formed in a pipe wall of the stainless steel pipeline; and the stainless steel pipeline is arranged on the back surface of the rolling cover. During operation, the oxygen generator is turned on; oxygen is input into the stainless steel pipeline through the plastic connecting pipeline and output through the small holes; and a whole rolling area is under a relatively stable oxygenation condition. The method breaks through the inherent thinking that the traditional rolling operation is limited to natural environment conditions; an operation environment is under a certain oxygenation condition all the time; freshness of rolled tea can be effectively improved; further, the organoleptic quality of a black tea product is improved; the black tea product is moist in appearance, high, stable and persistent in fragrance and mellow in taste; and an effect of the method is obviously better than that of the traditional rolling operation.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and relates to a tea rolling method, in particular to an oxygen-increasing rolling method for black tea processing. Background technique [0002] Kneading technology is an important technology in the tea-making process, which is very important for forming curls and hair peaks for tea tasting; rolling is mainly completed by rolling equipment, which is an important equipment in tea processing machinery. It was developed in the early 1950s For the first time, an all-wooden two-person hand-push kneading machine appeared. The kneading plate was made of hard linden, the rest was made of ordinary wood, and the ribs were inlaid with bamboo chips; , instead of the manual rolling machine, and at the same time realized the semi-mechanized operation of tea processing; in the 1960s, the improved rolling machine was mainly driven by a diesel engine and a motor, and an automatic heavy pressing device app...
