Description
Technical Field
The invention relates to a steam boiler, in particular to an overheated steam boiler for steaming tea leaves.
Background
Steaming is one of the fixation means in tea processing, and steam is needed to provide heat energy in the steaming process. The steam adopted by green steaming in the prior art is saturated steam, one is saturated steam with pressure, and is provided by a common steam boiler which mainly comprises a fuel system, a smoke and air system, a steam-water system and the like. The other is normal pressure saturated steam which is generated by a normal pressure steam generator in the tea steaming machine and is used for directly carrying out enzyme deactivation on the tea. The steam temperature generated by the steam boiler or the steam generator is low, the moisture content is high, and the tea leaf steaming machine is used for steaming tea leaves, and firstly, the tea leaves are not completely killed, and especially, the raw material of the raw dark green tea with more than 1 bud and 5 leaves can hardly be killed to meet the requirements; secondly, the moisture content of the tea leaves after steaming is very high, which is not beneficial to the implementation of the subsequent process, and the processed green tea product has low quality and can not produce high-grade green tea; thirdly, the steaming time is long, the steaming amount cannot be improved, and the production efficiency is low. Therefore, the industry considers that the steam is used for tea enzyme deactivation, is only suitable for the production of middle-grade and low-grade green tea, and cannot be used for the production of high-grade green tea and the processing of black hair.
Disclosure of Invention
The invention aims to overcome the limitations and prejudices of people in the prior art and discloses an overheated steam boiler for steaming tea leaves, which has high steam temperature and low water vapor content, can meet the steaming requirements of high-grade green tea production and black wool processing, and has simple structure and low operating cost.
The technical solution of the invention is as follows: a superheated steam boiler for steaming tea leaves comprises a boiler body, an inner container arranged in the boiler body, a water bin arranged between the boiler body and the inner container, a steam bin arranged above the water bin, a heat absorption pipe arranged in the inner container and communicated with the water bin, a discharge flue arranged at the top of the inner container, a hearth arranged at the bottom of the inner container, and a saturated steam outlet arranged at the top of the boiler body and communicated with the steam bin, and is characterized in that: and a superheated steam heating pipe is arranged in the hearth, one end of the superheated steam heating pipe is communicated with a saturated steam outlet through a saturated steam pipe, and the other end of the superheated steam heating pipe is in superheated steam output connection with the superheated steam pipe through a superheated steam outlet.
The invention adopts the technical scheme, overcomes the restriction existing in the prior art and the prejudice of people, can generate high-temperature superheated steam with the temperature about 300 ℃ higher than the saturated steam temperature under the condition that the manufacturing cost and the energy consumption are the same as those of a common boiler with the same specification, can quickly and thoroughly kill tea leaves no matter the tea leaves are old and tender, can meet the requirements of steaming and killing green tea, and can meet the requirements of quickly steaming over 1 bud and 5 leaves of raw black raw tea. Because the steam content of the high-temperature superheated steam is low, the steamed green tea material is dry and comfortable, and the method can be used for producing the steamed green of high-grade green tea. Also has the advantages of simple structure, convenient operation and low cost.
