[0001] The utility model belongs to the technical field of tea extraction, and in particular relates to a crushing-free extraction device for compressed tea. Background Art

[0002] With the trend of diversified selection of raw materials for tea beverages, more and more traditional compressed tea is used as raw material for tea beverage industry. Since compressed tea has been pressed and shaped, it has a hard and dense texture and a large weight, which is not conducive to direct extraction. Therefore, in previous production practices, it is necessary to use professional equipment to break the tea bricks or manually beat them before entering the extraction. The tea leaves and tea powder after the tea bricks are broken are then used as raw materials for the extraction stage.

[0003] There are the following problems with crushing tea leaves before soaking: manual pounding and crushing of compressed tea is time-consuming and laborious, and cannot guarantee the standardization of the degree of crushing and the uniformity of the particle size of the broken tea leaves; mechanical crushing of compressed tea can guarantee the standardization of the degree of crushing and the uniformity of the particle size of the tea leaves to a certain extent, but has the following defects: first, the strong mechanical crushing will increase the content of broken tea and tea powder, which will cause the bitterness of the extracted tea to increase; second, the strong mechanical crushing will produce a lot of noise, which is not conducive to the factory's EHS management; third, the crushing capacity of existing equipment is limited, generally one side is manually feeding slowly, and the other side is slowly discharging, which affects production efficiency.

When fumigating tea leaves, Fuzhuan tea is put into a liftable immersion basket 3, the immersion basket 3 is extended into the tank body 1, the sealing cover 2 covers the tank body 1, and the steam nozzle 11 sprays 98-120°C food water vapor to the Fuzhuan tea in the immersion basket 3, and the tea leaves are fumigated for 120-420s to enter the tea steaming mode; when spraying tea leaves, the spray head 21 sprays hot water to the Fuzhuan tea, the water flow pressure in the spray head is set to 1-5bar, the spray flow rate is 1000-4000L / H, the temperature is set to 95±1°C, and the spray time is controlled to be 120-420s. Under the two forces of lateral spray pressure and gravity through the spray heads at different positions, the Fu brick tea can be more effectively and deeply infiltrated, which is beneficial to further soften the tea brick structure; when boiling tea, the tea brick structure is basically loose after the spraying is completed, and hot water with a temperature of 95±1℃ is injected into the tank to 3600L. The lifting rod 4 is lowered to lower the immersion basket 3 below the water level, and the tea leaves are soaked for about 60-480s. When the soaking is completed, the immersion basket 3 is lifted above the liquid surface to separate the soup and residue, the control valve of the water outlet of the tank body is opened, and the output pump is turned on to pump out the tea soup for cooling. After the tea soup is output, the cover 2 is opened and lifted, the immersion basket 3 is lifted, the residue is manually cleaned and the tank body 1 and the immersion basket 3 are cleaned.
