firstly, a proper amount of maltose or sucrose is put into the popcorn sugar preparation cavity 74; the high-temperature flue gas burned in the food preparation heat source 37 is continuously guided into the lower end of the spiral flue gas guide channel in the interlayer 73 through the hot flue pipe 12, so that the high-temperature flue gas in the spiral flue gas guide channel in the interlayer 73 flows upwards in a spiral shape, and finally the flue gas is continuously discharged from the upper end of the spiral flue gas guide channel in the interlayer 73 through the smoke discharge pipe 53; in the process that high-temperature flue gas flows through the spiral smoke guide channel in the interlayer 73, the heat exchange inner container 72 is always in a relatively high-temperature state; the heat of the heat exchange liner 72 ensures that the maltose or the cane sugar in the popcorn sugar preparation cavity 74 is always kept in a molten state;
the popcorn preparing unit discharges prepared popcorn into the popcorn feed hopper 82 through the discharge pipe 8, then controls the popcorn transfer shaft 81 to rotate continuously, further causes the popcorn transfer blade 79 and the stirring rod 75 to rotate synchronously, the stirring of the popcorn transfer blade 79 causes the popcorn in the popcorn transfer cylinder 70 to feed downwards continuously, further causes the discharge port at the lower end of the popcorn transfer cylinder 70 to lead out the popcorn to the bottom of the popcorn sugar preparing cavity 74 continuously;
meanwhile, the stirring bar 75 keeps the popcorn candy preparing chamber 74 in a stirring state, and the popcorn introduced to the bottom of the popcorn candy preparing chamber 74 is mixed with the maltose or sucrose hot slurry in the popcorn candy preparing chamber 74, and the popcorn in the bottom of the popcorn candy preparing chamber 74 is gradually stirred and dispersed in the maltose or sucrose hot slurry in the stirring state in a floating manner due to the relatively low density of the popcorn; until the popcorn is uniformly dispersed in the whole popcorn candy preparing cavity 74, the on-off valve 78 is finally opened on the finished product delivery pipe 77, and then the liquid pumping device pumps out the maltose or sucrose hot slurry with the popcorn dispersed in the popcorn candy preparing cavity 74, and then the hard popcorn candy is formed after the maltose or sucrose hot slurry with the popcorn dispersed is cooled, and finally the preparation of the popcorn candy is completed after the working procedures of cutting and the like are carried out.
The preparation method of the popcorn preparation unit comprises the following steps:
step one, opening a first opening and closing valve 6, closing a second opening and closing valve 7, introducing raw rice into a spiral channel 38 through a feeding pipe 5, driving a rotary cylinder 23 to rotate through a synchronous belt unit through a synchronous wheel 30, and enabling an integrated structure formed by a disc body 44, a push column 26, a connecting frame 22 and a sealing ring 40 to synchronously rotate with the rotary cylinder 23 under the action of a transmission column 31 and a transmission hole 29; under the stirring of the spiral auger transmission blade 25, the raw rice is uniformly distributed in the spiral channel 38, then the first opening and closing valve 6 is closed, and a closed space is formed in the spiral channel 38; then the synchronous belt unit drives the rotary drum 23 to periodically and continuously rotate in the intermittent positive and negative directions through the synchronous wheel 30, so that the raw rice in the spiral channel 38 is in a continuous rolling state, and the rolling state is maintained until the third step is finished;
step two, simultaneously starting a circulating fan 16 and a flame burner (36), wherein the circulating fan 16 forms continuous upward flowing gas in the first circulating pipe 15, and the flame burner (36) forms continuous flame in the combustion chamber 14, so that the inner shell 42 and the conical inner shell top 18 generate a continuous high-temperature state, and further the gas flowing through the first air heating gap 17 and the second air heating gap 13 is continuously heated;
the heated air flowing out of the first circulating pipe 15 under the action of the circulating fan 16 sequentially passes through the right annular cavity 19, the right vent hole 20, the right end of the spiral channel 38, the left end of the spiral channel 38, the left vent hole 2, the left annular cavity 9, the second circulating pipe 10, the second air heating gap 13 and the first air heating gap 17, and finally returns to the first circulating pipe 15 again to form air internal circulation;
the air is heated by the inner shell 42 and the conical inner shell top 18 all the time in the process of the air internal circulation, so that the temperature of the air in the whole air internal circulation is continuously raised until the temperature of the air in the air internal circulation is raised to be enough for roasting the raw rice rolling in the spiral channel 38; because high-temperature air continuously flows through the spiral channel 38 in the air internal circulation process, the raw rice turning over in the spiral channel 38 is gradually and uniformly heated into cooked rice, and moisture in the cooked rice turning over in the spiral channel 38 is volatilized into the air circulation in the form of water vapor;
because the air internal circulation is a closed internal circulation system, the air pressure in the air internal circulation is gradually increased due to the temperature rise and expansion of the gas in the internal circulation system and the expansion effect of the water vapor until the air pressure in the air internal circulation reaches 4-5 atmospheric pressures, so that a high-pressure high-temperature environment which continuously rolls is formed in the spiral channel 38 until the rice which rolls in the spiral channel 38 is completely cooked;
step three, starting the linear push rod motor 33 to enable the push rod 34 to do rapid extension movement, at this time, the push rod 34 drives the integrated structure formed by the disc body 44, the push column 26, the connecting frame 22 and the sealing ring 40 to rapidly move leftwards along the axis of the pressure relief column cavity 35, and the transmission column 31 slides along the axis direction of the transmission hole 29; at the moment, due to the displacement of each sealing ring 40, the outer ring of each sealing ring 40 is staggered with each ring of pressure relief holes 24, so that all the pressure relief holes 24 are quickly communicated with the pressure relief column cavity 35, at the moment, high-pressure gas in the spiral channel 38 is quickly and uniformly discharged through each pressure relief hole 24, at the moment, the inside of the rolled rice grains in the spiral channel 38 is still in a high-pressure state, so that high-pressure steam in the rice grains is rapidly expanded, and the rice grains are instantaneously exploded, so that the popcorn food is formed;
and step four, opening the second opening and closing valve 7, driving the rotary cylinder 23 to continuously rotate in the positive direction by the synchronous belt unit through the synchronous wheel 30, further gradually pushing the popcorn in the spiral channel 38 to the left under the stirring and pushing of the spiral auger transmission blade 25, and finally discharging the popcorn through the discharge pipe 8.
