Background
The compressed tea is brick-shaped or cake-shaped tea which is prepared by taking black tea, old green tea, banker tea and other suitable raw tea as raw materials through typical technological processes of piling, steaming, pressing and the like. The tea is also a cylindrical thousand-two-piece tea, and the tea is named after the net content of each roll (branch) of tea leaves is equal to one thousand two-piece old scale, and the tea roll is also named as flower-rolled tea because the bamboo basket on the outer surface of the tea roll is packaged into a lattice shape. Most varieties of compressed tea are coarse and old, and the dried tea is black brown, and the soup color is clear yellow or clear red. Is very popular in minority nationality areas. The compressed tea has the characteristics of good moisture resistance, convenience in transportation and storage, mellow tea taste, suitability for weight reduction and the like.
Cake tea: is tea which is formed by steaming and pressing and has a flat cake-shaped appearance. Seven tea cakes are often used as a limit, and are packaged into a barrel by bamboo shoots, so the tea is also called as seven-seed cake tea. Every piece of traditional seven-seed cake tea has a net weight of 357 g, the diameter of the cake is 21 cm, the center thickness is 2 cm, and the edge thickness is 1 cm: there are two kinds of "raw cake" and "cooked cake". In recent years, various kinds of cake tea in the form of "cake" have appeared in large numbers in compliance with market demands. 200 g, 400 g and 500 g of cake are common, and the cake is bigger and smaller, and is shaped like 'coin', round and mesoporous 'copper coin tea', and the like. Its general meaning is different and sufficient.
The brick tea is generally rectangular in shape and is 35 multiplied by 18 multiplied by 3.5 cm in specification. The brick surface is right, four corners are smooth, and the mould lines (trademark patterns) are clear. The color of the brick surface is black brown, the fragrance of the inner body is pure, the taste is thick and slightly astringent, the soup color is red Huang Weian and She Delao, the net weight of each brick is different from 2 kg.
The compressed tea needs to be opened before brewing, and then brewing is carried out. The pressed cake tea and brick tea are very firm due to the shape and the process, and are not easy to disassemble, and the pressed cake tea and brick tea are required to be brewed by means of tea knives and tea cones, so that the pressed cake tea and brick tea have the defects that firstly, the pressed cake tea and brick tea are inadverted by hands due to improper operation, secondly, the pressed cake tea and brick tea are scattered, so that a plurality of broken tea dust appear during brewing, tea tasting is influenced, more theophylline can be released during brewing, the taste of the tea soup becomes more bitter and astringent, the drinking effect of the product is influenced, thirdly, the size of the divided small blocks is different, the tea water proportion cannot be effectively controlled, the thickness of the taste of the tea soup and the thickness of a liquid layer are greatly influenced, and the fragrance, the taste and the color of the soup are changed.
For this reason, the design patent 2013304412685 discloses a tea opener for opening tea cakes, which is similar to a conventional tea knife in function although it is different in shape from the conventional tea knife.
The utility model patent number 2013206573421 discloses a puer tea cutting machine. The four-bar mechanism multiplies pressure through a lever principle to drive the blade to reciprocate, so that block cutting of block puer tea is realized.
The utility model patent number 2012200918147 discloses a compressed Pu' er tea-Tuo tea opener. The device is characterized in that a screw rod with a pressure head moves relative to a bottom support/collection box with a bottom cutter, so that compressed Pu' er tea-bowl-shaped compressed tea can be opened.
In order to facilitate tea making, compressed tea is also divided into required shapes by adopting a saw blade mode. The utility model patent of patent number 2014203977112 discloses a compressed tea cutting machine, which cuts compressed tea (Qianliang tea) into tea cakes or cuts compressed tea cakes and bricks into small tea blocks through a moving saw blade.
The tea making devices are all small tea blocks with high density and small lump shape, and soup (tea) discharging speed is low when brewing. And the cutting heat generated in the pressing cutting and sawing process has adverse effect on the quality of the finished black tea.
