Embodiment 1

[0020] In this embodiment, the device for heating three-stage flue-cured tobacco using solar energy includes a solar heat collector 1, a hot water storage tank 2, a solar heat collecting circulation pump P1, a heating circulation pump P2, a fan heat exchanger P3, and a solenoid valve , temperature sensor, control cabinet 10. The ultra-clear tempered low-iron glass cover plate in the solar collector 1 has a transmittance ≥ 92%, and the metal heat absorber with a selective absorption coating in the heat collector 1, and the heat absorber can be a strip Or the whole board, the structure of the heat absorbing body is that there are fins at both ends of the tubular flow channel or fins on the upper part, and the material is copper or copper-aluminum composite material. The insulation material is rock wool, glass wool board or strip. The inlet 1-1 of the solar heat collector 1 is equipped with a pipeline 5 communicating with the lower circulation port 2-1 at the bottom of one side ...

Embodiment 2

[0039]The solar heat collector in this embodiment is a vacuum tube heat collector, including a vacuum tube, a header, a bottom bracket, a tailstock, and a tube head. The structure of the header is that there is an insulation layer on the shell between the inner tanks, and one side of the header (vertical insertion type) or two symmetrical sides (horizontal insertion type) have circular holes. One end of the vacuum tube opening is inserted into the row hole of the header and goes deep into the inner tank of the header. The other end of the vacuum tube is set on the tailstock and installed on the bottom bracket together. There is a bracket between the header and the bottom bracket. Other structures are the same as in Embodiment 1, and the control status setting of the control cabinet is also the same as in Embodiment 1.

[0040] During use, the heat supply pipe 9 of the present invention and the hot air blower or heat exchanger are contained in the flue-cured tobacco chamber 3. ...

Abstract

The invention discloses a heat supply device for curing tobacco at three sections with solar energy. The device comprises a solar heat collector, wherein the inlet and the outlet of the solar heat collector are communicated with a hot water storage tank respectively; the other side of the hot water storage tank is provided with a heating circulating water outlet and a heating circulating water inlet; a heat supply circulating water outlet pipe and a heat supply circulating water inlet pipe are arranged on the heating circulating water outlet and the heating circulating water inlet respectively; a heat supply pipe which is positioned in a tobacco curing chamber is arranged between the two pipes; and a hot air fan or a heat exchanger is arranged in the tobacco curing chamber. In the invention, solar energy heat supply and auxiliary heat supply for the tobacco curing chamber are adopted, so that the indoor temperature of the tobacco curing chamber is raised; the temperature in the hot water storage tank can be up to 30-99 DEG C according to different solar radiation amounts and different weather conditions of different places; and by using solar energy, the indoor temperature of the tobacco curing chamber can be raised to 30-70 DEG C, the consumption of the conventional energy is lowered, and the pollution is greatly lowered.

Description

technical field [0001] The invention relates to a heating device for curing tobacco, in particular to a three-stage flue-cured tobacco heating device using solar energy as energy or auxiliary energy. technical background [0002] The principle of flue-cured tobacco is based on the quality of fresh tobacco and changes in the baking process, using certain heat and ventilation and humidity control methods to provide corresponding temperature, humidity and duration, etc., to promote sufficient and perfect physiological and biochemical changes in tobacco leaves. The yellowing of the tobacco leaves and the dehydration drying are coordinated, and finally the tobacco leaves are yellowed, dried and fragrant. [0003] The baking of normal tobacco leaves is divided into yellowing stage, color fixing stage and gluten drying stage. [0004] Tobacco leaf change requirements in the yellowing stage, the yellowing degree of the lower tobacco leaves reaches 80% yellow; the yellowing degree o...
