The invention discloses an internal-circulation bulk curing barn realizing
complementation of multiple energies. The internal-circulation bulk curing barn comprises four parts, including a tobacco loading chamber, a heating chamber, a dehumidifying chamber and a
system master controller, wherein three
heat transfer devices in the heating chamber carry out heat exchange with air in the heating chamber by adopting
solar energy, air energy and
electric energy, with the tobacco loading chamber, damp and hot air separating out in the
tobacco leaf curing process is exhausted into the dehumidifying chamber for cooling and dehumidification, the damp and hot air after cooling and dehumidification returns to the heating chamber to be heated, and the
system provides heat and eliminates
humidity by adopting the
complementation method according to the baking process curve and the temperature and
humidity in the tobacco loading chamber. The internal-circulation bulk curing barn realizing
complementation of multiple energies has the beneficial effects that a heat source is provided in a complementation manner by adopting four energies including
solar heat collection, air energy, solar photovoltaic and
electric energy, the dehumidification manner combining internal-circulation dehumidification and total heat
recovery dehumidification is adopted, thus the curing cost can be reduced, the temperature
rise time can be shortened, the
system master controller is adopted for realizing control, so that the manual operation can be reduced, the labor intensity can be alleviated, the control precision can be promoted, and the
tobacco leaf curing quality can be improved.
