Description

A kind of fermentation drying chamber
Technical field
The invention belongs to Fu-brick tea processing equipment fields, and in particular to a kind of fermentation drying chamber.
Background technique
Fu-brick tea is a kind of post-fermented tea, and fungus growing process is the critical process of Fu-brick tea quality responses, during floating The accurate equal control of temperature and humidity is the key factor of Fu-brick tea quality.Currently, Fu-brick tea fermentation drying chamber generally use steam and The Combination Design of cooling fin achievees the effect that temperature automatically controlled control is wet.But due to drying chamber inner air under the action of heat buoyancy from It on down, flows back by top back reflection, causes drying chamber bottom, head temperature high, the low temperature difference band of medium temperature.In addition, Fu Moisture constantly scatters and disappears and generates certain fermentation fever brick tea in brick during the fermentation, causes temperature and humidity inside drying chamber uneven.For this purpose, Application No. is 201520220410.7 Fu-brick tea drying chamber the intracorporal top of drying chamber be provided with can uniformly hydrofuge and exhaust fan Carry out the hydrofuge pipe device of pipeline connection, can uniform hydrofuge, but will cause the loss of a large amount of thermal currents simultaneously, the energy of waste. Further, application No. is a kind of energy saving drying chamber of baking brick tea of 201521026266.X, it by circulating fan is connected with drying chamber The heat exhausting pipe for receiving heat pipe and lower part at top, forms the circulation for receiving heat with heat extraction, substantially reduces energy consumption, improves heat energy efficiency, But due to receiving heat pipe, heat exhausting pipe inside drying chamber in " analog-U shaped " distribution, it is uneven to cause local heating, and limitation height is only fitted It is baked for brick tea, is not suitable for brick tea floating.In addition, application No. is 201611240005.7 fermenting house thermal cycle recyclings Method will accumulate in the dress water cavity that hot-air at the top of fermenting house is recycled to steam generator by exhaust fan, recovery channel, will be hot The heat transfer of air realizes that thermal cycle recycles, reduces energy consumption to hot water.Likewise, application No. is 201710677208.0 a kind of Fu tea floating drying chamber and its application method is taken out hot wind by being located at the exhaust tube at the top of drying chamber To the blast pipe of biomass thermal wind furnace, it is sent into drying chamber again after hot wind stove heating, forms hot air circulation, significantly reduce energy consumption, But steam generator and biomass thermal wind furnace can equally generate thermal energy in the process of running simultaneously, cause energy waste.
Summary of the invention
The present invention provides a kind of fermentation drying chamber, its purpose is optimizes the uniformity of temperature and humidity in drying chamber, solves hair The problems such as fermentation fever and equipment thermal energy generated during flower recycles, further increases the floating quality of Fu-brick tea, improves Heat utilization rate plays energy-efficient effect.Its specific technical solution is as follows: a kind of fermentation drying chamber, it is characterised in that including Drying chamber ontology, equipment room, heat-collecting box, blower, heat-dissipating pipe, air return system, refrigeration machine, dehumidifier, wet-emitting blower, humidifier, temperature Humidity sensor and fresh wind port;The drying chamber ontology is connected with equipment room, constitutes fermentation drying chamber;The heat-collecting box is located at equipment In, it is connected with external water inlet pipe and jet chimney;The heat-dissipating pipe is preferably finned heat-dissipating pipe, further preferably U-shaped wing Shape heat-dissipating pipe, top be equipped with flow air duct, preferred air port be evenly distributed on flow air duct on, the air port caliber size according to It is secondary gradually to successively decrease from stream air duct proximate, it is further preferred that be equipped with deflector inside stream air duct;The U-shaped wing Shape heat-dissipating pipe is located at two sides of the bottom in drying chamber ontology, with the heat-collecting box being located in equipment room, constitutes the heat cycles of fermentation drying chamber System;The air return system is equipped with two-way blower fan, is located at the intrinsic top of drying chamber, and is distributed in two sides of the bottom in equipment room Blower forms the airflow circulating mode of drying chamber ontology " from bottom to top ", and realizes the thermal energy exchange with equipment room internal gas flow.Institute It states refrigeration machine to be located on equipment room inner wall, circulation temperature lowering is carried out to drying chamber ontology by blower and air return system, is further being returned Cooling device is equipped in wind system to cool down to air-flow.The dehumidifier is located in equipment room, wet-emitting blower and humidification seat in the plane In on equipment room inner wall or outer wall, the wet system of drying chamber control of fermenting is constituted.
System operation control model is divided into floating and drying mode;The floating mode is using steam in heat-collecting box Hot water heated, and combine the heat exchange action of drying chamber ontology and equipment room air-flow, reach the drying chamber internal temperature of fermenting Dynamic equilibrium, at the same using refrigeration machine, humidifier, dehumidifier, wet-emitting blower carry out refrigeration control it is wet;The high temperature drying mode, It is directly to be heated to heat-dissipating pipe using steam, and the heat exchange action of drying chamber ontology and equipment room air-flow is combined to reach fermentation The dynamic equilibrium of drying chamber internal temperature, while hydrofuge is carried out using dehumidifier and wet-emitting blower, until brick tea is dry.
Compared with other Fu tea ferment drying chamber, this fermentation drying chamber is had the advantages that
1, fermentation drying chamber is made of drying chamber ontology and equipment room, realizes drying chamber ontology " from bottom to top " by blower and air return system Airflow circulating effect, the thermal energy for making full use of fermentation fever and equipment to generate when running realizes the heat of drying chamber ontology and equipment room Exchange interaction improves heat utilization rate, significantly reduces energy consumption.
2, heat-collecting box is connected by pipeline with the heat-dissipating pipe of drying chamber ontology ground two sides, passes through booster pump and solenoid valve respectively Realize recycling for thermal energy and being precisely controlled for different temperatures mode.
3, by being equipped with air return system in drying chamber bodies top center, fermentation is not only effectively recycled using two-way blower fan Heat realizes the equilibrium of drying chamber body interior temperature, while passing through cooling device fast cooling, energy-saving consumption-reducing.
