Description

A corn syrup heating tank Technical Field

[0001] This utility model relates to the field of biological fermentation equipment technology, and in particular to a corn syrup heating tank. Background Technology

[0002] Corn steep liquor, a byproduct of corn starch production, contains abundant amino acids, vitamins, and growth factors, and is an inexpensive organic nitrogen source. Its rich nutritional components promote cell growth and improve fermentation acid production and sugar-acid conversion rates. In amino acid fermentation production, corn steep liquor plays a crucial role as an organic nitrogen source and growth factor supplier. It is rich in biotin and limiting amino acids, significantly influencing the amino acid fermentation process. By increasing the amount of corn steep liquor used, some organic nitrogen sources, such as soybean meal hydrolysate, yeast powder, and hair powder, can be reduced or replaced, thereby lowering the cost of amino acid production. Corn steep liquor can also serve as a high-quality feed additive and raw material, providing animals with the necessary nutrients. It is rich in protein, amino acids, vitamins, and minerals, improving the nutritional composition of feed and increasing its palatability and nutritional value.

[0003] Corn steep liquor plays a crucial role in amino acid fermentation, but it contains a large number of contaminating bacteria, such as Bacillus. Bacillus requires a high sterilization temperature, and corn steep liquor often contains impurities that can encapsulate these bacteria. Incomplete sterilization during fermentation can easily lead to contamination, affecting the fermentation process. Therefore, further treatment of the corn steep liquor is necessary to reduce the risk of contamination.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0024] Example 1:

[0025] Referring to Figure 1, this utility model provides a corn syrup heating tank, including a tank body, a stirring device is provided inside the tank body, a heating component is provided at the bottom of the stirring device, and a discharge pipe 9 is provided at the bottom of the tank body.

[0026] The stirring device includes a stirring shaft 4, a stirring mechanism 12 is provided at the bottom of the stirring shaft 4, and a motor 3 is connected to the top of the stirring rod 4. The motor 3 provides power for the stirring shaft 4 to rotate, thereby driving the stirring mechanism 12 to rotate.

[0027] Specifically, referring to Figures 2 and 3, the stirring shaft 4 includes an outer shaft 41 and an inner shaft 42 fixedly sleeved together, with the inner shaft 42 protruding from the outer shaft 41; the portion of the inner shaft 42 protruding from the outer shaft 41 is a threaded shaft.

[0028] The stirring mechanism 12 includes a stirring rod 121 and an anchor-type stirring paddle 127. The anchor-type stirring paddle 127 provides a large stirring range, reduces the likelihood of dead zones, and allows the corn slurry to tumble better and be heated evenly within the tank. The stirring rod 121 is mounted on the outer shaft 41 via a fixing sleeve 122, positioning it in the center of the tank. A detachable frustum-shaped support block 123 is provided at the bottom of the fixing sleeve 122 to support the stirring rod 121 when not in operation. Furthermore, the fixing sleeve 122 has notches 125, the number of which is equal to the number of stirring rods 121; preferably, two stirring rods 121 are provided. The stirring rods 121 are rotatably mounted on the inner wall of the notches 125 via pins 124. The anchor-type stirring paddle 127 is rotatably connected to a threaded shaft. The stirring rod 121 is movably connected to the outer shaft 41. When the outer shaft 41 rotates, the stirring rod 121 rises under the action of centrifugal force. If the outer shaft 41 rotates at low speed, the stirring rod 121 can also rotate under the support of the truncated cone support block 123. The truncated cone support block 123 is detachable, and different truncated cone support blocks 123 with different tapers can be selected according to requirements.

[0029] Referring to Figure 4, the top of the truncated cone support block 123 is provided with a threaded connection part 126, and the lower part of the inner wall of the fixing sleeve 122 is provided with a thread that is adapted to the threaded connection part 126. The truncated cone sidewall of the truncated cone support block 123 serves to support the stirring rod 121.

[0030] Referring to Figure 1, the heating component includes a coil that can be heated by steam. Steam circulates within the coil, heating the corn syrup inside the tank, increasing the heating area, ensuring even heating of the corn syrup, and conserving resources.

[0031] The coil includes a horizontally arranged annular pipe 6 and multiple sets of vertical pipes 15 vertically connected to the annular pipe 6. Preferably, there are four sets of vertical pipes 15, arranged symmetrically in pairs. Each set of vertical pipes 15 has 10 pipes. Steam enters each set of vertical pipes 15 through the lower steam inlet pipe 7 and exits through the upper steam outlet pipe 5.

[0032] The diameter of the annular tube 6 should be 2 / 3 of the diameter of the tank body to avoid the middle part being poorly heated if the diameter is too large, or the edge part being unheated if the diameter is too small.

[0033] The top of the tank is equipped with a corn slurry inlet pipe 2 and an air pipe 1. When alkaline boiling is required in the tank, the corn slurry inlet pipe 2 can also serve as an alkaline solution inlet pipe. The air pipe 1 extends to the bottom of the tank. When the viscosity of the corn slurry is too high, air can be introduced through the air pipe 1 during the stirring and rotation process, which is more conducive to the uniform mixing of the corn slurry. The air pipe 1 can also serve as a steam inlet pipe for air purification of the heating tank.

[0034] Example 2:

[0035] Referring to Figure 5, this utility model provides a corn syrup heating tank, which differs from the above embodiment in that: the coil includes two sets of intersecting spiral tubes, and a gap is provided between the two sets of intersecting spiral tubes. When the anchor stirring paddle 127 rotates between the two sets of spiral tubes, the corn syrup can flow through the gap, increasing the contact between the corn syrup and the spiral tubes, thereby increasing the temperature of the corn syrup and making the temperature of the corn syrup in the tank more uniform.

[0036] The two sets of spiral tubes are a first spiral tube 6A and a second spiral tube 6B. The bottom of the first spiral tube 6A is connected to a first steam inlet pipe 10 and the top is connected to a first steam outlet pipe 11. The bottom of the second spiral tube 6B is connected to a second steam inlet pipe 7 and the top is connected to a second steam outlet pipe 5. This utility model can also be provided with only one set of spiral tubes.

[0037] The diameter of the coil is larger than the width of the anchor-type agitator 127, so that the anchor-type agitator 127 can rotate smoothly in the coil.

[0038] In this invention, the height of the stirring rod 12 is set to half that of the tank, and the coil is placed at the bottom of the tank. This arrangement ensures that the stirring area is maximized.

[0039] This invention provides a corn syrup heating tank. When the stirring shaft rotates, the stirring rod and anchor-type stirring paddle work together to better and more evenly mix the corn syrup. The tank body is equipped with a coil, which, compared to conventional heating jacket heating, increases the heating area of ​​the corn syrup inside the tank, shortens the heating time, and saves resources. There is a pipe on each side of the tank head. The left pipe can serve as a corn syrup inlet pipe or an alkali inlet pipe for alkali sterilization of the heating tank. The right pipe can serve as an air inlet pipe, used to introduce air when the corn syrup viscosity is too high, which is beneficial for uniform mixing; the right pipe can also serve as a steam inlet pipe, which can be used for air sterilization of the heating tank after alkali sterilization. This corn syrup heating tank is more suitable for production needs.

[0040] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
