A fragrant system of processing of floral type black tea aroma raising includes: the method comprises a dynamic withering process 1, a secondary fermentation process 2, a continuous strip tidying process 3 and a continuous drying process 4, wherein the dynamic withering process 1 comprises a withering process 11 and a rocking process 12, the withering process 11 comprises a withering tank 111 and a blower 112, the withering process 11 is realized by uniformly tiling fresh tea leaves after transportation in the withering tank 111, blowing and drying the tiled fresh tea leaves by the blower 112, processing the rocking process 12 by the blown fresh tea leaves, performing a rapid dehydration process 121 in the processing process, performing the secondary fermentation process 2 on the tea leaves after the rapid dehydration process 121, and continuously performing the continuous strip tidying process 3 and the continuous drying process 4 on the tea leaves after the secondary fermentation 2.

The fresh leaves can generate a large amount of heat in the transportation process, the fresh leaves are quickly placed into a withering trough for even spreading after entering a factory, and a blower is turned on for withering, so that the temperature of the leaves can be reduced, and the fresh leaves can be kept in a certain freshness; on the other hand, the water loss of the fresh leaves can be promoted, and the conversion of the content material components can be regulated and controlled. The green rocking process can promote the generation of fragrant substances such as terpenes, hexenes, linalool and the like, and simultaneously increases the mechanical damage degree of large cells, thereby being beneficial to hydrolyzing to generate high-boiling-point fragrant substances; before the fragrance is fully developed, rapid dehydration treatment is carried out to remove partial water, so that fresh leaves become soft and are continuously broken during rolling, the integrity can be kept, and meanwhile, the obvious fragrance can be kept;

the method adopts a dynamic withering process, namely combines the sunning and rocking technologies, realizes that the fragrance of the black tea can be improved without adding exogenous substances, and has strong flower fragrance.

The traditional black tea has short fermentation time and is formed once, so that the tea is not fermented sufficiently, and the fragrance cannot be completely emitted. The project innovatively adopts a secondary fermentation method, the fermentation time is prolonged and is 2 times of that of the traditional black tea processing, and the increase of terpene components such as geraniol, linalool and oxides thereof and nerolidol is accelerated in the long-time fermentation process of the tea leaves, so that the tea leaves are more aromatic;

the secondary fermentation method is adopted to ensure the tea to be fully oxidized and is beneficial to the formation of aroma substances.

The drying process of the novel process of the floral black tea is continuously carried out, so that the continuous tea strip tidying and continuous drying are realized, the tea strip tidying machine is connected with the chain plate type automatic dryer, on one hand, the moisture in the tea can be removed, the tea strip rope can be tightened, on the other hand, the conversion of the components in the tea can be promoted, and a foundation is laid for the black tea to exert the fragrance and the taste of the black tea, wherein the high-temperature quick strip tidying technology refers to a red tea pot of a small variety of black tea, and the enzymatic activity is damaged by high temperature, so that part of polyphenol compounds are not oxidized, the color conversion is stopped, the tea fragrance is enhanced, and the taste is improved;

the purposes of fragrance improvement and fragrance preservation are achieved by adopting a high-temperature quick strip tidying technology and a continuous drying technology.

A method for aroma improvement processing of flower-fragrance black tea comprises the following steps:

s1, rapidly and uniformly spreading the transported fresh leaves on the withering trough 111 after entering the field, and turning on a blower to wither the fresh leaves;

s2, starting a rocking process while starting a blower for withering, and rocking the fresh leaves in the withering process;

s3, fermenting the withered tea leaves, wherein the fermentation time is twice as long as that of the traditional black tea processing;

s4 the tea strip tidying machine is connected with the chain plate type automatic dryer, and the fermented tea is quickly injected into the tea strip tidying machine to be dried while being high-temperature strip tidying is carried out.

The working principle of the floral black tea aroma-improving processing system provided by the invention is as follows:

rapidly and uniformly spreading the transported fresh leaves above the withering trough 111 after entering a field, and turning on a blower for withering;

starting a rocking process while starting an air blower for withering, and rocking fresh leaves in the withering process;

fermenting the withered tea leaves, wherein the fermentation time is twice of that of the traditional black tea processing;

the tea leaf strip tidying machine is connected with the chain plate type automatic dryer, and the fermented tea leaves are quickly injected into the tea leaf strip tidying machine to be dried while being high-temperature strip tidying is carried out.

Compared with the related art, the aroma improving processing system for the floral black tea provided by the invention has the following beneficial effects:

by adopting the technologies of dynamic withering, secondary fermentation, continuous strip tidying, continuous drying and the like, the fragrance of the black tea is improved, the fragrance time is prolonged, and the problem of heavy bitter taste of the traditional black tea is solved, so that the black tea has strong fragrance, mellow taste, sliding property and soaking resistance.

A withering device for use in combination in place of the withering trough 111 of the floral black tea aroma-raising processing system of claim 1, the withering device for use in combination comprising: the air conditioner comprises a support frame 5, wherein a first air inducing hole 51 is formed in one side of the support frame 5, a second air inducing hole 52 is formed in the other side of the support frame 5, and a connecting pipe 53 is fixedly connected to one side of the support frame 5; at least two mounting heads 6, at least two of the mounting heads 6 are fixed on one side of the support frame 5, mounting grooves 61 are formed on the mounting heads 6, and mounting bolts 62 are arranged on the mounting heads 6; the exhaust fan 7 is arranged on one side of the support frame 5, an exhaust pipe 71 is arranged at the input end of the exhaust fan 7, an exhaust pipe 72 is arranged at the output end of the exhaust fan 7, and connecting pieces 73 are fixedly connected to the top and the bottom of the exhaust fan 7; a withering frame 8, wherein the bottom of the withering frame 8 is fixed on the top of the support frame 5.

Air exhauster 7 through easy to assemble and dismantlement, thereby conveniently demolish air exhauster 7 from the top of support frame 5, demolish convenient splicing to two looks isostructure's support frame 5 behind the air exhauster 7, when needs splice, only need aim at the inside of the first induced air hole 51 on another support frame 5 with connecting pipe 53 on one support frame 5 and insert, air exhauster 7 on another support frame 5 is in the state of demolising this moment, make and communicate each other between two support frames 5 through first induced air hole 51 and connecting pipe 53, thereby the convenient frame 8 that withers to support frame 5 top splices the use.
