Description

Static state fermentation device of black tea

Technical Field

The invention relates to the field of black tea processing equipment, in particular to a static fermentation device for black tea.

Background

The black tea is one of six tea types in China, and meanwhile, China is also the origin of the black tea, and the high-quality black tea has the characteristics of red and bright liquor color, fragrant and mellow taste and pure and long-lasting fragrance. Modern researches show that the black tea contains a large amount of phenolic substances which have the functions of resisting oxidation, reducing blood fat, inhibiting arteriosclerosis, enhancing capillary vessel function, resisting mutation and the like, so that the black tea is beneficial to human health after being drunk frequently. Drinking black tea also increases the content of vitamin B1 in the liver, which means that drinking black tea frequently helps promote the secretion of enzymes in the liver, helps the normal operation of liver cells, reduces the metabolic burden of liver cells, etc.

The black tea is a fully fermented tea, and is prepared by using proper tea tree fresh leaves as raw materials and refining the tea through a series of processes such as withering, rolling (cutting), fermentation, drying and the like. Each step in the preparation process of the black tea affects the quality of the tea leaves, wherein fermentation is a key process for expressing the quality of the black tea, namely black tea fermentation, which is a series of chemical change processes mainly comprising oxidation of polyphenols under the enzymatic action, but the oxidation process needs to be stopped after fermentation to a certain degree, so that the phenomenon that aerobic fermentation is excessive is avoided, lactic acid and carbon dioxide are generated when aerobic fermentation is carried out after the polyphenols are completely fermented, which seriously affects the quality of the black tea, and the tea leaves become thin, soft and non-shaped, so that the aerobic fermentation process needs to be stopped timely, and anaerobic fermentation needs to be carried out for a certain time after the oxidation process is stopped.

Modern research has found that fermentation of black tea is also an anaerobic biological oxidation of the substrate, i.e. the substrate is subjected to a glycolysis process to produce volatile substances. In general, fermentation and respiration of plant tissues are performed simultaneously, and this is a normal physiological state, but in the case of normal respiration, aerobic respiration process dominates, so that the intensity of fermentation is relatively low, and therefore, in the absence of oxygen, the respiration process can be interrupted, and respiration is converted into fermentation to maintain life activities, so that the effect of fermentation is intensified. Therefore, fermentation of the black tea under the static anaerobic condition has important significance for improving the quality of the black tea, the obtained black tea has stronger tea aroma and the color of tea soup is brighter.

In order to make the processed black tea have superior quality, the applicant filed application on the same day for a static fermentation process of the black tea, which adopts the static fermentation of the black tea on the water surface, wherein a fermentation tank and a wooden fermentation box are adopted in the process, a water inlet and a water outlet are arranged on the fermentation tank, the rolled tea is put into the fermentation tank, the fermentation tank is put into the fermentation tank filled with clear water, the fermentation tank floats on the water surface, and the clear water in the fermentation tank is kept to flow. In the technical process, the labor intensity is high when the materials are discharged, the fermentation boxes need to be taken out from the fermentation tank one by one, and then the tea leaves are manually taken out from the fermentation boxes, so that the labor intensity is high, and the working efficiency is low.

Aiming at the technical problems, the invention provides a static fermentation device for black tea, which aims to solve the technical problem of high labor intensity in discharging in the conventional static fermentation process of black tea.

In order to solve the technical problems, the invention provides the following technical scheme: a static fermentation device for black tea comprises a fermentation box and a water storage box, wherein the water storage box comprises a water inlet and a water outlet, and further comprises a high baffle, a low baffle and two mirror-symmetrical side plates; the upper edges of the side plates are obliquely arranged from the high baffle plate to the low baffle plate; the top of the side plate is provided with a groove, and a lifting rod is arranged in the groove; the top of the side plate is also provided with a telescopic push rod which is positioned between the high baffle and the groove; the low baffle is hinged with a barb, and the free end of the barb is provided with a magnetic block.

Support columns are arranged at two ends of the fermentation box, the fermentation box is positioned in the water storage tank, the support columns are movably supported at the tops of the lifting rods, and the distance between the lifting rods and the side wall of the groove is smaller than the outer diameter of the support columns; the side plate of the fermentation box, which is opposite to the low baffle plate, comprises a fixed plate and a movable plate positioned at the upper end of the fixed plate, the movable plate is hinged with the fixed plate, and the outer surface of the movable plate is provided with an iron block attracted with the magnetic block; the position of the supporting column is lower than that of the fixing plate.

The working principle of the invention is as follows: the clear water of packing into in the storage water tank, it flows to keep the clear water, during the ejection of compact, the lifter rises, rise the notch that exceeds the recess with the support column, then start flexible push rod, because the support column activity is supported in the top of lifter, so when the effort of flexible push rod is used on the support column, the top roll-off of support column follow lifter, because the interval between lifter and the recess lateral wall is less than the external diameter of support column, so the support column can directly slide to the curb plate, because the top of curb plate is to the lopsidedness of low baffle, so the support column will take the fermenting case to slide to low baffle. When sliding to the fixed block and contacting with low baffle, upwards rotating the barb, the magnetic path on the barb attracts with the iron plate on the fly leaf, then rotates the barb downwards, like this alright rotate fly leaf along its articulated department with the fixed plate, just so opened the fermenting case, carry out the ejection of compact of tealeaves.

The invention has the beneficial effects that: through curb plate, lifter, flexible push rod and the iron plate and the magnetic path of inter attraction that the slope set up in this scheme, the simple convenient ejection of compact of having realized tealeaves compares in prior art, and the labour that the ejection of compact consumed weakens greatly, has the beneficial technological effect who reduces intensity of labour.

The optimization of the basic technical scheme is as follows:

the first optimization scheme is as follows: the water storage tank also comprises a plurality of partition plates which are arranged in parallel at intervals, and the partition plates are parallel to the side plates; the upper edges of the partition plates are obliquely arranged from the high partition plate to the low partition plate, a water storage cabinet is formed between the adjacent partition plates, and the water storage cabinet is also formed between the side plate and the adjacent partition plate; the top of the clapboard is also provided with the groove and the lifting rod positioned in the groove; the fermentation boxes and the barbs are multiple and correspond to each other in the same number and positions, the fermentation boxes are connected in the horizontal direction through connecting columns, and the fermentation boxes are located in the water storage cabinet; the connecting column supports and the lifting rod, and the connecting column and the supporting column are located on the same horizontal line. The tea leaf discharging device can discharge tea leaves of a plurality of fermentation boxes at a time, and further improves the working efficiency.

And the second optimization scheme is based on the first optimization scheme: and a blocking block is arranged at the top of the low baffle. Avoid because when tealeaves is more, inertia is too big and make whole fermenting case roll-off outside the low baffle, so set up more again and block the piece and play better effect of blockking.

And the optimization scheme III is based on the optimization scheme II: the bottom of the fermentation box is obliquely arranged, and the height of the lower end of the bottom of the fermentation box is the same as that of the fixing plate. Thus, the discharging is better and convenient.
