Embodiment
Technical scheme is described further below in conjunction with accompanying drawing, but required protection domain does not limit to
In described；
The invention provides a kind of tea drier and drying tea leaves method, as shown in figure 1, the tea drier includes
Body 1, the top of body 1 is provided with evaporation web plate 2, bed board 3 and blower fan 4 is sequentially provided with from bottom to top in body 1, and body 1 is interior certainly
Combustion chamber 5, drying chamber 6 and return passage 7 are divided into successively on down, and bed board 3 is provided with multiple through holes 31, and the density of through hole 31 is
20-40 every square centimeter, the outer wall of body 1 is provided with return duct 8, and one end of return duct 8 connects with return passage 7, return duct 8
The other end connects with drying chamber 6.Included using tea drier provided by the present invention and drying tea leaves method, tea drier
Body, is provided with combustion chamber, drying chamber and return passage in body, using during the tea drier, it is necessary to which first tealeaves and starch are mixed
Conjunction is configured to mix bed, then fuel is used gasoline as in combustion chamber, and gasoline is in flue gas caused by burning Indoor Combustion
Mix with mixing bed, and flowed over repeatedly in combustion chamber and backflow circulating inside, tealeaves under the guiding of blower fan
Fully contacted with compounding substances such as high-temperature flue gas, starch in journey and heat exchange, and experienced repeatedly circulation and flow repeatedly, make tealeaves
Discharged after the water vapour evaporation on surface from the evaporation plate at the top of body, it is in this process, imperfect combustion in combustion chamber
High-temperature flue gas burnt away under the flow regime of drying chamber, discharge substantial amounts of heat energy, fuel is fully burnt, carry
High burning conversion efficiency, therefore the waste to fuel source is avoided, reduce environmental pollution.
The roof of return passage 7 is provided with striker plate 9, the inwall of outside body 1 connection of striker plate 9, and the middle part of striker plate 9 is along perpendicular
Nogata is to raising up.The main function of striker plate 9 is to play drainage, in the presence of drainage blower fan and striker plate 9,
Because the burning-point of starch is very high, about 380 degrees Celsius, therefore, starch only serves the effect for transmitting heat wherein, and starch is not
Burning, but transfers heat to tealeaves surface, takes away tealeaves surface moisture, and starch also edible, therefore, after tealeaves
The processing of phase and edible it can not damage.
The material of striker plate 9 is the spring steel that the trade mark is 65Mn.By striker plate 9, make the tealeaves by drying in backgauge
Rebounded on plate 9, so as to promote tealeaves downwards out of return duct return drying chamber in continue to dry so that tealeaves obtain completely and
Sufficiently drying, the main function of striker plate 9 is to play drainage.
Drainage blower fan 10 is additionally provided with return duct 8.Tealeaves, starch and high-temperature flue gas are accelerated by draining blower fan 10
Flowing velocity, the rate of heat exchange of quickening, improves efficiency.
The material of bed board 3 is the steel alloy that the trade mark is W18Cr4V.W18Cr4V steel alloy has excellent heat conductivility,
Again because bed board 3 is provided with multiple through holes 31, the fuel of completely burned discharges substantial amounts of heat through over invalid bed board in combustion chamber
It is transferred in drying chamber, and high-temperature flue gas imperfect combustion in combustion chamber is passed through and filled in the entrance drying chamber of through hole 31 with tealeaves
Divide mixing to burn away, fuel is fully burnt, improve thermal energy conversion efficiency.
The outer wall of combustion chamber 5 is provided with fuel -supply pipe 11, and fuel -supply pipe 11 is provided with front pump 12.Further, it is
Fuel is set further to burn, can also to input oxygen in combustion chamber fire-retardant.
Front pump 12 is booster pump.Using booster pump, improve the pressure of fuel, so that in combustion chamber in unit volume
Fuel density increase, the possibility of fuel completely burned is significantly lifted.
The present invention also provides a kind of drying tea leaves method, and specific embodiment has：
