[0045] A freeze-dried instant porridge preparation method using a freeze-dried instant porridge preparation device, including the following steps:

[0046] S1: washing the raw material rice with drinking water; then placing the washed raw material rice on a mesh screen to drain for 2 to 3 minutes;

[0047] S2: The drained raw rice is loaded into a frame with a thickness of 18-22 cm and frozen at -15 to -20°C for 6-8 hours;

[0048] S3: The frozen raw rice and water are mixed at a mass ratio of 1:11-13 and placed in the second cooking barrel 24, and vitamin E is added. The mixture is cooked by the heating mechanism 3 for 20-30 minutes, and then the heating mechanism 3 is changed by the switching mechanism 4 for 10-20 minutes to obtain a semi-finished product;

[0049] S4: The semi-finished product is evenly poured into a mold and cooled to room temperature. The cooled semi-finished product is frozen at -15 to -18°C for 10-15 hours, and then frozen at -30 to -40°C for 5 hours. The quick-frozen semi-finished product is placed in a freeze-drying chamber with a vacuum degree of 60-100 and a cold trap temperature below -30°C for freeze-drying.

[0050] Working principle: The raw rice is washed with drinking water, and then drained on a mesh screen for 2-3 minutes. The drained raw rice is loaded into a frame with a thickness of 18-22 cm and frozen at -15 to -20°C for 6-8 hours;

[0051] The frozen raw rice and water are mixed at a mass ratio of 1:11-13 and placed in the second cooking barrel 24, and vitamin E is added. The mixture is cooked by the heating mechanism 3 for 20-30 minutes, and then the heating mechanism 3 is changed by the switching mechanism 4 for 10-20 minutes to obtain a semi-finished product. After the semi-finished product is cooked by the heating mechanism 3 for 20-30 minutes, the pull rod 32 is pulled, which compresses the extension spring 34. At the same time, the extension spring 34 drives the charcoal rack 35 to move through the first spherical joint 39. Since the charcoal rack 35 is pulled, and the charcoal rack 35 is connected to the support rod 36, the charcoal rack 35 will tilt at this time. At the same time, the charcoal rack 35 compresses the extension rod 38, which can provide certain stability when the charcoal rack 35 moves. Since the charcoal rack 35 tilts, the charcoal on one side of the charcoal rack 35 will roll to the other side, thereby moving the charcoal at the bottom of the second cooking barrel 24 to the bottom of the first cooking barrel 23, reducing the fire at the bottom of the second cooking barrel 24, changing the heat of the rice porridge in the second cooking barrel 24, improving the viscosity and taste of the rice porridge, and avoiding strong rice grains and hard taste;

[0052] The semi-finished product is evenly poured into a mold and cooled to room temperature. The cooled semi-finished product is frozen at -15 to -18°C for 10-15 hours, and then frozen at -30 to -40°C for 5 hours. The quick-frozen semi-finished product is placed in a freeze-drying chamber with a vacuum degree of 60-100 and a cold trap temperature below -30°C for freeze-drying.

[0053] In the process of changing the fire by pulling the pull rod 32, the charcoal fire frame 35 drives the stirring shaft 41 to move. In the initial state of the charcoal fire frame 35 driving the stirring shaft 41 to move, since one end of the stirring shaft 41 is connected with the guide frame 31, the charcoal fire frame 35 moves first, and then the stirring shaft 41 moves through the second spherical joint 44. When the stirring shaft 41 moves, the stirring shaft 41 drives the stirring page 43 to move the charcoal fire in the charcoal fire frame 35. Then, when the charcoal fire frame 35 continuously moves and drives the stirring shaft 41, the sliding block 46 on one end of the stirring shaft 41 slides in the guide frame 31. Since the gear 47 on one end of the stirring shaft 41 is connected with the gear teeth 45, the stirring shaft 41 rotates through the gear 47 while the sliding block 46 slides. The stirring shaft 41 rotates and drives the stirring page 43 to rotate. Therefore, in the process of changing the fire by pulling the pull rod 32, the stirring shaft 41 moves to stir the charcoal fire in the charcoal fire frame 35, so that the contact area of the charcoal fire with air increases, and the combustion efficiency of the charcoal fire is higher, which saves cost and resources.

[0054] In addition, the stirring shaft 41 moves to stir the charcoal fire in the charcoal fire frame 35, which can push the charcoal fire to move in the charcoal fire frame 35, assist the charcoal fire in the charcoal fire frame 35 to move, avoid the charcoal fire from piling up together, and affect the change of the fire by pulling the pull rod 32. The charcoal fire can adopt a spherical shape, which facilitates the movement of the charcoal fire in the charcoal fire frame 35.

[0055] In addition, in the process of the stirring shaft 41 moving to stir the charcoal fire in the charcoal fire frame 35, the charcoal ash and charcoal residue generated by the combustion of the charcoal fire can fall into the inside of the dust collecting box 42 through the charcoal fire frame 35 and be collected by the dust collecting box 42. On the one hand, the combustion efficiency of the charcoal fire can be improved, and on the other hand, the charcoal ash and charcoal residue can be collected to avoid the dispersion of the charcoal ash and charcoal residue to the outside and affect the working environment.

[0056] In addition, after pulling the pull rod 32 to change the fire, a part of the charcoal fire is transferred to the bottom of the first cooking barrel 23 to heat the clean water inside the first cooking barrel 23, so that the charcoal fire at the bottom of the first cooking barrel 23 can heat the clean water inside the first cooking barrel 23, thereby the clean water inside the first cooking barrel 23 can be heated while cooking the rice porridge inside the second cooking barrel 24, and after the rice porridge inside the second cooking barrel 24 is cooked, the next batch of rice porridge to be cooked can be directly poured into the inside of the first cooking barrel 23 and cooked by the heated clean water inside the first cooking barrel 23, which not only prevents the bottom from being burnt, but also makes the rice grains directly heated at high temperature and quickly cooked and expanded, which not only shortens the long time of boiling cold water and saves time for cooking, but also because of direct high-temperature heating, the expansion speed of the rice grains from raw to cooked is accelerated, which is more likely to cook and improve the taste of the rice porridge. By pulling the pull rod 32 to change the fire, the clean water inside the first cooking barrel 23 and the rice porridge inside the second cooking barrel 24 are heated at the same time, the processing steps are reasonably planned, not only saving operation time and steps, but also improving the taste of the rice porridge.

[0057] After cooking, the pull rod 32 can be pushed to drive the charcoal fire frame 35 to move, so that the charcoal fire inside the charcoal fire frame 35 moves to one end of the charcoal fire frame 35. After the charcoal fire frame 35 moves to a certain position, the top rod 52 on the charcoal fire frame 35 will contact the cover 51, and one end of the cover 51 will be magnetically attracted to the top rod 52. At this time, the charcoal fire frame 35 moves several times, the cover 51 drives the top rod 52 to move, and the top rod 52 rotates on the charcoal fire frame 35. At this time, the charcoal fire inside the charcoal fire frame 35 will fall from the inside of the charcoal fire frame 35 to the inside of the ash collecting box 42. Since the ash collecting box 42 is filled with carbon ash and carbon residue, the charcoal fire falls into the carbon ash and carbon residue, which extinguishes the charcoal fire. Not only can the carbon ash and carbon residue be effectively utilized, but also the staff can avoid taking the charcoal fire, which may be dangerous if the charcoal fire falls off.

[0058] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
