Description

Technical Field

[0001] The utility model relates to the technical field of brewing technology, in particular to a raw material steaming device. Background Art

[0002] In the production process of vinegar, soy sauce, wine, etc., the raw materials usually need to be steamed and boiled. After steaming, the starch granules in the raw materials absorb water, swell, rupture and gelatinize, thereby improving the saccharification and fermentation capacity, while also being able to remove impurities and sterilize.

[0003] In the production process of traditional vinegar, soy sauce and wine, it is necessary to reduce the temperature of raw materials such as rice, corn and sorghum to a suitable temperature in time after steaming, and fermentation can begin after mixing with koji. At present, the commonly used steaming device usually only has the function of steaming, such as a steaming device for brewing vinegar disclosed in Chinese Patent Publication No.: CN213012760U, which includes a fixed frame, four supporting legs are fixedly installed at the bottom of the fixed frame, an electric heating pot penetrating the fixed frame is movably installed on the top of the fixed frame, and the front and back of the right end of the electric heating pot are fixedly installed with connecting shafts penetrating the front and back of the fixed frame respectively, a stirring motor is fixedly installed at the bottom of the electric heating pot, and the output end of the stirring motor is fixedly installed with a stirring rack located inside the electric heating pot, and the opposite sides of the two left supporting legs are movably installed with electric rods movably connected to the front and back of the electric heating pot respectively. The steaming device for brewing vinegar can automatically stir the material during the steaming process to prevent uneven local heating from causing different maturity, and it is convenient for operators to carry out material feeding operations, which is more convenient and quick to use, effectively improves the efficiency of raw material steaming, and saves the time required for production.

[0004] However, the material steaming device for making vinegar only has the function of stirring while steaming. Although the mixing of cereals and bran can be completed by the rotation of the stirring frame, the stirring effect is not ideal because the stirring frame is at the bottom of the electric hot pot. Secondly, after the steaming is completed, the electric hot pot still needs to be pushed by an electric rod to rotate the electric hot pot to pour out the steamed raw materials, and then spread them out to cool, resulting in low cooling efficiency. Finally, the material steaming device for making vinegar still requires a large amount of manpower to transport the raw materials into the electric hot pot and to the cooling site after steaming during use, which is time-consuming and labor-intensive. The discharge effect by dumping is also not ideal. Residues are likely to exist around the stirring frame at the bottom of the electric hot pot. Transporting and cooling is also likely to pollute the surrounding environment, or cause the raw materials to be contaminated by miscellaneous bacteria, which is inefficient, so the use function is relatively limited. Summary of the invention

[0056] Example 2

[0057] When using the utility model, the reciprocating motor 114 is started, the fan-shaped baffle 111 is rotated downward to close the discharge port 11, and then the box cover 4 is opened, and the soaked rice, corn or sorghum and other grain raw materials are introduced into the filter 2 in the receiving box 1, and then bran, rice chaff and other materials that can increase looseness, supply oxygen and increase temperature are introduced into the filter 2 in the receiving box 1 in proportion through the feeding pipe 15, and then the box cover 4 is closed, and the stirring motor 35 is started. The stirring motor 35 drives the stirring and feeding mechanism 3 to rotate, and starts to stir and mix the materials above the filter 2. Since the spiral radius of the first spiral blade 32 on the stirring and feeding mechanism 3 is greater than the radius of the second spiral blade 33, and the spiral direction of the first spiral blade 32 is opposite to the spiral direction of the second spiral blade 33, when the stirring and feeding mechanism 3 rotates, the first spiral blade 32 and the second spiral blade 33 stir in opposite directions, so that the stirring efficiency is higher and the mixing is more complete;

[0058] After the mixing is completed, the drain pipe 14 at the bottom of the container box 1 is closed by starting the electromagnetic valve 141, and then water is injected into the bottom of the container box 1 through the water injection pipe 13. After the water is injected, the heating pipe 16 is started to heat the water in the container box 1, and the stirring motor 35 is started at the same time, so that the stirring and feeding mechanism 3 continues to stir the raw materials slowly, so that larger gaps are generated between the raw materials to facilitate steam penetration. The contact area between the raw materials and the steam is increased by continuous stirring, and the mixed raw materials are quickly steamed and gelatinized by the action of steam, and the raw materials are evenly heated at the same time;

[0059] After steaming for a period of time, the heating tube 16 is turned off, the solenoid valve 141 is closed, and the water at the bottom of the container 1 is discharged through the drain pipe 14. Then, the fan cover plate 42 on the top of the box cover 4 is fully opened, and the ventilation mechanism 41 is started. Since the ventilation mechanism 41 includes an air inlet fan 411 and an air outlet fan 412, the air inlet fan 411 and the air outlet fan 412 can accelerate the flow speed of the airflow after being started at the same time, increase the flow path of the airflow, and balance the air pressure inside and outside the container 1, so as to quickly take away the water vapor and heat in the raw materials; since a one-way cover plate 152 is provided at the end of the square oblique tube 151, the one-way cover plate 152 can cover the opening of the square oblique tube 151 after naturally rotating downward under the action of gravity, so as to prevent the water vapor blown out by the fan from entering the square oblique tube 151 during cooling; the stirring and feeding mechanism 3 can also be started again to continue stirring the raw materials, thereby increasing the contact area between the raw materials and the air and improving the efficiency of cooling the raw materials;

[0060] After the raw materials are cooled, the reciprocating motor 114 is started to rotate the fan-shaped baffle 111, thereby opening the discharge port 11. The raw materials are moved toward the discharge port 11 under the action of the first spiral blade 32 through the slow rotation of the stirring and feeding mechanism 3. After passing through the discharge port 11, the raw materials that have been mixed, steamed and cooled can be discharged along the guide plate 12, so as to facilitate collection and sorting and then adding koji for mixed fermentation. Since the outer edge of the first spiral blade 32 fits with the inner surface of the filter screen 2, the raw materials can be pushed by the first spiral blade 32 immediately after rolling down under the action of gravity, so that all the raw materials on the filter screen 2 can be discharged from the discharge port 11 under the pushing action of the first spiral blade 32.

[0061] Since the stirring, mixing, steaming, gelatinization and cooling of the raw materials are all carried out in one device, the number of times of collecting, transporting and spreading the raw materials is effectively reduced, saving a lot of labor, while improving the efficiency of raw material transportation and the sanitary environment during cooling, reducing the chance of raw materials being infected by miscellaneous bacteria, thereby greatly improving the production efficiency of fermented materials such as vinegar, soy sauce and wine.
