Description
Technical Field
The invention relates to a heat energy guiding device of a drum-type baking machine, in particular to a heat energy guiding device of a drum-type baking machine, when the drum-type baking machine is heated by the heating device, hot air flows from a plurality of hot air inflow ports to a hot air outflow port, hot air flows into a baking space to form a plurality of air flow heats by a plurality of guiding fins, and a physical heat conduction is generated between an inner drum and an outer drum by metal heat conduction materials of the plurality of guiding fins; so that when the air flow heat temperature is greater than the physical heat conduction, the air flow heat is temperature compensated to the physical heat conduction; on the contrary, when the temperature of the air flow heat is smaller than that of the physical heat conduction, the physical heat conduction is compensated by the temperature of the air flow heat, so that the temperature of the physical heat conduction and the temperature of the air flow heat are compensated, the constant temperature, the energy conservation, the uniform temperature and the heat preservation are achieved, and the coffee beans can achieve better baking quality with stable heat energy during baking.
Background
The coffee beans are typically roasted prior to being ground into the serving powder for brewing, which causes the beans to expand, darken in color and release a unique flavor during the roasting process, requiring sufficient heat to accelerate the reaction and other chemical reactions that add to their flavor. Although many coffee bean machines are currently available on the market, most of the conventional coffee bean machines only can be used for regulating and controlling the temperature, time and wind power, and the user needs to adjust the ratio of the thermal power output and the exhaust motor output of the coffee bean equipment at different temperature control points in order to conform to a pre-planned bean temperature curve. In the process of roasting raw beans, from starting up a coffee bean machine to heating up, putting the raw beans into the machine, looking at the temperature rise of the coffee bean machine, starting to rise the temperature until reaching a temperature return point, waiting for hearing a first explosion or waiting for a second explosion, and determining the roasting action such as the temperature of the lower beans, the technology is integrated, particularly the temperature rise change rate in the roasting process is controlled, the above experience hot air temperature and flow rate, pot temperature, pot rotating speed and time are combined to be the main factors of roasting, and the hot air flow rate, pot rotating speed, temperature and time are controlled by a baker after training and experience for a period of time, so that the quality of better roasting can be manufactured by virtue of the technical literacy of the baker, (1) the hot air is uneven, (2) the pot temperature is unstable and uneven, and (3) the fall of the hot air temperature and pot temperature is too large, but not controlled by a baker. Uneven roasting can cause coffee beans to generate bad taste and aroma, if the temperature of the rotary drum is too high, the surface of the coffee beans is too burnt and the burnt smell is generated, if the temperature is insufficient, the raw bean smell is easily generated, but the hot air temperature and the temperature of the rotary drum are improved by hardware improvement of a roasting machine, so that the internal thermostability of the roasting drum and the energy-saving effect have much room for improvement.
Referring to fig. 1A, a semi-hot air structure of a conventional roasting machine includes a furnace body C1, wherein a hot end C2 is disposed at one end of the furnace body C1, a drum C3 is disposed inside the furnace body C1, the drum C3 rotates through an axis C4, coffee beans C5 are accommodated in the drum C3, and a heat source C9 is directly disposed at the bottom end of the drum C3; however, the prior art has the advantage of faster heating speed, but the following disadvantages are caused by the direct butt joint of the heat source C9 to the drum C3: (1) The existing structure has uneven hot air temperature, so that the coffee beans can not be roasted with due aroma and taste; (2) The high drum temperature of the prior art structure will result in excessive burning of the coffee bean skin and the development of a burnt smell.
Referring to fig. 1B, a full hot air structure of a conventional baking machine includes a furnace body C1, wherein an outlet end C2 is provided at one end of the furnace body C1, a drum C3 is provided inside the furnace body C1, the drum C3 rotates through an axis C4, coffee beans C5 are accommodated inside the drum C3, an inner partition plate C61 and an outer partition plate C62 are provided at the bottom end of the drum C3, a channel C7 is formed between the furnace body C1 and the inner partition plate C61 and between the drum C3 and the outer partition plate C62, an inlet end C8 is provided at the bottom end of the channel C7, and a heat source C9 is provided at one side of the inlet end C8; although the structure of the prior 1-2 pattern is stable with respect to the hot air temperature of the structure of the 1-1 pattern, the prior structure of the 1-2 pattern is easy to cause insufficient heat and slow heating speed due to the layered barrier of the inner separator C61 and the outer separator C62; furthermore, the inner partition plate C61 and the outer partition plate C62 are in a fixed structure configuration, the heat source is transmitted to the rotary drum C3 and is guided only through the channel C7, and no indirect pan body temperature is used for conducting heat of the heat source C9, so that the heat temperature is intensively consumed in the inner partition plate C61 and the outer partition plate C62, and energy is wasted.
