Description
Technical field：
The invention belongs to crops processing technique field, and in particular to a kind of using photovoltaic generation, heat pump, bulk curing barn
Method for flue-curing tobacco leaves.
Background technology
1. present situation is applied in baking equipment for preparatory treatment of tobacco research
Barn is the essential basic equipment of cured tobacco production.Flue-cured tobacco is minimus one kind in tobacco various types, until
The present, cured tobacco production just have more than 100 years history.It is gravity-flow ventilation gas to be produced in past more than 100 years above most widely used
Flow ascending manner barn.Until hairs such as North Carolina state university Johnson seventies in last century (W.H.Johson)
Heated air circulation dense barn (bulk curing barn) is illustrated and is promoted rapidly in the U.S. and comes.China until the beginning of this century,
Ability popularity has been built with Chinese characteristics using coal as the tobacco flue-curing bulk curing barn of fuel, realizes barn
It updates, but holding at high price due to coal, and carbon emission amount is big, brings serious problem of environmental pollution.
2. air can utilize present situation
Air energy high temperature heat pump is a kind of heat lift device, it is to utilize inverse Carnot's principle, is recycling continuous refrigerant
Running system in, the air on periphery constantly transfers heat to refrigerant, after powering on, under the promotion of electric energy, refrigerant
In system internal circulation flow under the action of compressor, it completes gaseous boosting temperature-rise period in compressor, and (temperature is up to
100 DEG C), it releases the air in high temperature heat heating cigarette-filling house into interior machine, while oneself being cooled and being converted into flow liquid
State, after it runs to outer machine, liquid, which absorbs heat to evaporate rapidly, is again converted to gaseous state, while temperature drops to 0 DEG C~-10
DEG C, at this moment the air on heat dump periphery will continuously transfer heat to refrigerant.The high temperature heat pump efficiency of heating surface is much larger than
The efficiency of other heating equipments, it converts the electric energy of consumption to 4~6 times of electric energy, and kilowatt-hour is used when 4~6 degree of electricity.Heat pump
It is to utilize clean energy resource electric energy, obtains more air energy, do not have any pollution in operation, is the green ring that country widelys popularize
Protect equipment.
3. photovoltaic generation utilizes present situation
The mankind in 1839 have unexpectedly discovered photovoltaic effect, 1883, prepare and luminous energy is directly changed into the one of electric energy
Kind of semiconductor generator part ----big sun can battery, the U.S. in 1954 realizes that solar photovoltaic generation system generates electricity by way of merging two or more grid systems for the first time.
1986, the U.S. built up power 6.5MW maximum solar photovoltaic power plants in the world at that time.The nineties in last century, Germany, U.S.
State successively proposes million solar roof projects, and the solar grid-connected photovoltaic generations of 3~5KW are installed for 1,000,000 family resident roofs
System.The beginning of this century, China enter photovoltaic generation fast traffic lane, are quickly become photovoltaic generation big country, power.This year, we will be
Chenzhou, Hunan Province Guiyang County bulk curing barn roof is installed by one 30KW grid-connected photovoltaic power station.

The first step makes the big portion of the lower tobacco leaf of maturity turn yellow in the method for flue-curing tobacco leaves, is to instigate maturity lower
Tobacco leaf 80% turns yellow.
It is tested using the method for flue-curing tobacco leaves of photovoltaic generation, heat pump, bulk curing barn Trinity baking equipment for preparatory treatment of tobacco：
2016-2017 is control with bulk barn fuelled by coal in Luoping of Yunnan's cigarette district, intensive to air-flow ascending manner heat pump
Barn, airflow descending type compression heat pump bulk curing barn have carried out comparative study.The result shows that every kilogram of dry tobacco leaf toasts cost, air-flow
Ascending manner heat pump bulk curing barn, airflow descending type compression heat pump bulk curing barn and bulk barn fuelled by coal, for inferior leads, respectively
1.39,1.32 and 2.29 yuan, for middle leaf, respectively 1.78,1.31 and 1.92 yuan, for upper leaf, respectively 1.43,
1.28 and 2.88 yuan.Especially airflow descending type compression heat pump bulk curing barn eliminates the problem of ceiling tobacco leaf mould bundle, improves cigarette
Leaf baking quality, reduces coal consumption, is worthy of popularization.
Photovoltaic generation, air energy heat pump bulk curing barn use clean energy resource, remove burn coal pollution environment, tobacco flue-curing at
This high problem is worthy of popularization.The tobacco flue-curing Effect value of different airflow direction heat pump bulk curing barns, which obtains, further to be ground
Study carefully, this is exactly the purpose of this experiment.
1 materials and methods
1.1 test site
Yunnan Province Luoping cigarette district
1.2 test period
2016 and two baking seasons in 2017
1.3 material to be tested
Air-flow ascending manner heat pump bulk curing barn, airflow descending type compression heat pump bulk curing barn, each 1 of old bulk barn fuelled by coal.
1.4 experimental design
Experiment sets 3 processing, and 1 (T1) of processing is air-flow ascending manner heat pump bulk curing barn, and 2 (T2) of processing decline for air-flow
Formula heat pump bulk curing barn, processing 3 are bulk barn fuelled by coal, are compared (CK).
2 results and analysis
2.1 dry cigarettes toast cost
Test result shows heat pump bulk curing barn, either air-flow ascending manner (T1) or airflow descending type compression (T2), by
The control precision of humiture is than bulk barn fuelled by coal higher in baking process, basically according to baking process curve into
Row, so baking quality of tobacco improves.
2016~2017 years two baking seasons, upper, middle and lower portion tobacco leaf have respectively carried out a baked test, have toasted cost
Such as table 1~3.
1 lower tobacco leaf of table toasts cost statistics
2 middle part tobacco flue-curing cost statistics of table
3 upper tobacco leaf of table toasts cost statistics
Air-flow ascending manner heat pump bulk curing barn, airflow descending type compression heat pump bulk curing barn and bulk barn fuelled by coal, under
Portion's leaf, it is respectively 1.39,1.32 and 2.29 yuan that every kilogram of dry tobacco leaf, which is baked into this, for middle leaf, respectively 1.78,1.31
With 1.92 yuan, for upper leaf, respectively 1.43,1.28 and 2.88 yuan, reduce cost up to 7.29%~55.56%.
The above result shows that air energy heat pump bulk curing barn, either air-flow ascending manner or airflow descending type compression, also without
Beam is lower part, middle part or upper tobacco leaf, and tobacco flue-curing cost is below bulk barn fuelled by coal, and cost efficiency is apparent.
Influence of the 2.2 different airflow direction heat pump bulk curing barns to quality of tobacco
In Luoping cigarette district, all it is to use air-flow rising-type bulk curing barn at present, mould bundle is usually generated for ceiling tobacco leaf
Phenomenon.So-called mould bundle is that tobacco leaf base portion is spread and sunk in stem, in addition spread and sink in piece the case where.Producing reason is local height above sea level, tobacco leaf
Baking season is slow, and the moisture of baking tobacco leaf early period abjection encounters colder barn ceiling and condenses into water, and droplet drops onto tobacco leaf
Base portion generates caused by brown chemical reaction when temperature is further up in barn.
3 brief summaries
This test result shows air energy heat pump bulk curing barn, either air-flow ascending manner or airflow descending type compression,
Tobacco flue-curing cost is below bulk barn fuelled by coal.But there is larger difference between different airflow directions.It is most important
Difference is the problem of airflow descending type compression heat pump bulk curing barn eliminates ceiling tobacco leaf mould bundle, improves baking quality of tobacco, is dropped
Low coal consumption.But, either air-flow ascending manner heat pump bulk curing barn or airflow descending type compression heat pump bulk curing barn, all compare
Bulk barn fuelled by coal is good, not only increases baking quality of tobacco, reduces coal consumption, is worthy of popularization.
