According to tobacco flue-curing basic program, when baking tobacco leaves start i.e. first stage tobacco leaf yellowing stage, temperature
Remain 36 °C -- 38 °C, not hydrofuge.Damp and hot boil in a covered pot over a slow fire of fresh picking tobacco leaf just is made tobacco leaf softening jaundice in baking room,
This stage generally maintains 48 hours or so, and time length becomes according to leaf tobacco production picking tobacco leaf size plumpness degree and observation tobacco leaf
Depending on yellow degree, this stage running uses open type hot wind mode.As shown in Figure 1, the first air-valve 71 is opened at this time, the second air-valve 72
It closes, third air-valve 73 is closed.Baking room hot air circulation flow is：
Hot wind --- circulating fan 81--- air outlet 11--- orifice-plate types air duct 13--- heating institute drying article --- return air inlet
12--- the first air inlet 51--- heat pipe condenser section 41--- heat pump condenser 32--- circulating fans 81.
And open type hot wind mode, it is that the evaporator 33 of heat pump and surrounding air open and lead to.It is responsible for absorbing in outdoor air
Heat and by condenser 32 be discharged into drying baking room in, endothermic process is：
Outdoor fresh air --- the 4th air-valve 74--- heat pipe evaporator section 42--- evaporator with heat pump 33--- evaporator fans 82---
Cold fresh air is discharged.
In the open type hot wind mode operation in this stage, air in baking room not with contacting external air, i.e. baking room
It is interior to be discharged without moisture, also enter without outdoor fresh air.And with contacting external air in the work of evaporator with heat pump 33, it is extraneous
After fresh air has been extracted heat when evaporator 33, then it is discharged in ambient atmosphere again.
Tobacco flue-curing second stage is the fixation stage of tobacco leaf, this stage needs a large amount of hydrofuges, temperature to control at 39 °C ---
42 °C, 30 hours duration.This stage dries mode operation using enclosed, as shown in Fig. 2, evaporator fan 82 is closed,
4th air-valve 74 is closed, and the 5th air-valve 75 is closed, and drying hot wind sequence of flow in baking room is：
--- circulating fan 81--- orifice-plate types air duct 13--- heating institute drying article --- the article discharge by heating hot dry wind
Hot-air after humidification --- return air inlet 12--- third air inlet 53--- heat pipe evaporator sections 42, condensed water discharge --- thermo-compression evaporation
Device 33, heat pipe condenser section 41--- heat pump condensers 32--- is heated for condensed water discharge --- relatively cool dry air after hydrofuge ---
Hot dry wind.
In this stage running, pattern is dried using enclosed hydrofuge, gas is not contacted with ambient atmosphere in baking room, hydrofuge according to
Condensation under 42 refrigerating state of evaporator with heat pump 33 and separate heat pipe evaporator section makes discharge in institute's heating object product body
Moisture, condensed water is discharged to by condensate collector 9 outside baking room.It is to pass through row rather than other kinds of heat pump dryer
Go out the damp-heat air outside baking room.
The tobacco flue-curing phase III is the drying stage of tobacco leaf, this stage needs a small amount of hydrofuge, temperature to control at 43 °C ---
68 °C, 36 hours or so duration.This stage is combined operation using enclosed drying pattern and open type pattern time segment,
At 43 °C --- time segment open type and enclosed interaction operation during 55 °C, at 56 °C --- open type hot wind mode is used during 68 °C
Until drying terminates.
In a complete drying course, open type hot wind mode when is used, when uses enclosed hydrofuge
Drying pattern, is automatically controlled by controller, and according to warm and humid sensor and input program, it is electronic to automatically open or close each position
Air-valve and wind turbine, automatic conversion open type or enclosed pattern.
The equipment combines the advantages of open type and enclosed are dried, the shortcomings that overcoming them, is reached by the switch of control valve
To the switching between open type and enclosed.In the overall drying process, the air in baking room dries always not with contacting external air
Tobacco flavor in stove room does not outflow, and to greatest extent all condenses in the fragrance of tobacco leaf in dry tobacco leaf, the tobacco leaf after drying
The high several class of tobacco leaf that color, fragrance and appearance will all be produced than existing common heat pump baking room.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
