during the period that the heat supply mechanism 3 and the spread-drying box 2 bake the tea leaves in the spread-cloth cavity 212, the exhaust fan 42 synchronously works in the air gathering box 41 to form an accelerating airflow group, and the accelerating airflow group is respectively exhausted from the opening of the drying frame 1 through the diversion ventilation channel 44, so that an accelerating disturbance airflow can be formed at the periphery of each layer of the spread-drying box 2, the water vapor volatilized by the tea leaves in the spread-drying box 2 can be quickly exhausted from the periphery of the spread-drying box 2 along with the disturbance air, the water vapor at the periphery of the spread-drying box 2 can not be smoothly exhausted to cause the moisture to regain the tea leaves, the arrangement of the separation frame 222 and the air passing hole 223 can facilitate the circulation of the water vapor volatilized in the spread-drying box 2, and the arrangement of the distribution air mechanism 4 can effectively avoid the occurrence of the condition that the tea leaves fly along with the airflow in the mode that the horizontal disturbance air drives the peripheral air to circulate compared with the traditional direct blowing type air blowing device.
Example 2:
the difference from embodiment 1 is that the connection pipe 33 at the position of the circulation pump 34 includes a pipe body 331, a variable-diameter block 332 is disposed inside the pipe body 331, the variable-diameter block 332 is a gradually-changing type solid column with a large middle part and small ends, the two ends of the variable-diameter block 332 are fixedly connected with the inner wall of the pipe body 331, and the pipe body 331 at the position of the variable-diameter block 332 is a perspective window 333, so that a user can conveniently check the working condition of the circulation pump 34 at any time, and the working artifact caused by the static water column or the idle running of the circulation pump 34 is effectively prevented; a heating wire can be additionally arranged in the water storage superheater tank 31;
as shown in fig. 10, in the process that the circulation pump 34 performs reciprocating circulation on the water in the storage superheat tank 31, a user can observe the water flow condition in the connection pipe 33 from the position of the perspective window 333, and because the water flow passes through the position of the variable-diameter flow-blocking block 332, the water flow speed changes due to the change of the inner diameter of the pipe body 331 and impacts on the variable-diameter flow-blocking block 332, the water flow in the area generates a 'coagulated bead' water flow shape similar to bubbles, so that the user can determine the normal operation of the heat supply mechanism 3, and the wrong work recognition caused by the damage of the circulation pump 34 or the circulation pump 34 due to the insufficient water in the storage superheat tank 31 is avoided, so that the user considers the normal operation thereof;
in addition, if user's area of locating takes place continuous overcast and rainy weather influence during using this device, the user can move this device indoor, replaces sunshine to carry out the heat supply by the heater strip, carries out low temperature "water bath" heat supply like embodiment 1, and the condition that this device can't normal use takes place during avoiding overcast and rainy weather.
