Description
Technical field
The present invention relates to tobacco leaves to modulate field, and the refrigerating and heating type closed cycle heat pump of especially a kind of adjustable airflow direction dries
Barn and its application method.
Background technique
Bulk curing barn is reducing labor intensity, is improving flue-cured tobacco entirety baking quality, adapting to cured tobacco production large-scale development etc.
Aspect has obvious advantage, it has also become the capital equipment of China's tobacco flue-curing.Currently, China respectively produces the intensive of cigarette district application
Most of barn is that the bulk curing barn or bulk curing barn group that comprehensive [2009] No. 418 files are built are done according to domestic cigarettes, based on coal
Want the energy.It often bakes the dry cigarette of 1kg and generally requires consumption 1.5-2.0kg coal, energy consumption is higher, and pollution is larger, and baking is caused to become cigarette
The careless main pollution source of agricultural production.Pollution that caused by coal burning in baking process is reduced to have become in modern tobacco agriculture progradation suddenly
Problem to be solved.China is energy consumption big country, is readjusted the energy structure, and carrying out tobacco flue-curing using new energy is a kind of necessarily to select
It selects, tobacco flue-curing is a kind of simply and effectively selection using electric energy Substitute coal.
The existing barn in current China is air-flow ascending manner or airflow descending type compression, is installed once barn is built, then gas
It is unadjustable to flow direction.In the practical baking of tobacco leaf, cigarette-filling house generally fills 3-4 layers of cigarette, according to different tobacco flue-curing stages, air-flow
Lower layer's tobacco leaf temperature upper layer tobacco leaf of the bright tips temperature lower layer tobacco leaf temperature of down type roasting room, air-flow ascending manner barn
Temperature will be higher by 1-3 DEG C, cause upper and lower level tobacco flue-curing progress inconsistent.And adjustable airflow direction barn then may be implemented
Lower layer's temperature it is consistent, to realize the consistent of tobacco flue-curing progress.
In addition, under the overall background that National Tobacco Leaves production scale significantly " goes production capacity ", each cigarette district in the whole nation plant cigarette area by
Year is reduced, and leads to part barn facility resources idle, assets is caused to waste.In recent years, many cigarette districts utilize barn lay-up period kind
Mushroom is planted, barn utilization efficiency is improved, effectively increases tobacco grower's income.Mushroom suitable growth temperature is but each between 15-28 DEG C
The currently used coal-fired barn of cigarette district and a small amount of heat pump barn cause barn to be unable to satisfy mushroom production in summer without refrigerating function
Requirement to temperature.Therefore, refrigerating and heating type air source heat pump curing equipment is researched and developed, for improving barn utilization rate, increases tobacco grower and receives
Benefit, while realizing that the cleaning baking of flue-cured tobacco green has important practical significance.
