DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The following is a further detailed description of the present utility model in conjunction with the attached Figure 1-4 drawings.
[0030] Please refer to the drawings in the specification Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model is provided: a high-pressure steaming device for fermented soybean meal, including a steaming box 1, a sealing frame 2 slidably sleeved on the upper side of the steaming box 1, two fixing grooves 3 opened on the side of the sealing frame 2, and a support plate 4 fixedly installed at the bottom of the steaming box 1, with a groove 5 opened at the bottom of the support plate 4.
[0031] An annular groove 6 is provided on the side of the inner wall of the groove 5. Two L-shaped strips 7 are rotatably arranged inside the annular groove 6. A handle 8 is fixedly installed at the bottom of the two vertical strips of the two L-shaped strips 7. Two Chinese character-shaped grooves 10 are provided on the side of the support plate 4. A fixing piece 9 is slidably arranged inside the Chinese character-shaped groove 10.
[0032] Working principle: When using this high-pressure steam cooking equipment for fermented soybean meal, the soybean meal to be cooked is placed inside the cooking chamber 1. Then, the sealing frame 2 is placed on the cooking chamber 1, and the two fixing slots 3 are aligned with the sides of the horizontal bars of the L-shaped insert 903. Next, the handle 8 drives the two L-shaped bars 7 to rotate, so that the horizontal bars of the L-shaped bars 7 rotate until they are no longer in contact with the sides of the vertical bars of the T-shaped bars 901. The two T-shaped bars 901 are then closed in the middle by the rebound force of the compression spring 902, which moves the horizontal bars of the L-shaped insert 903 into the fixing slots 3. This causes the sealing strip 401 to move into the sealing slots, sealing the cooking chamber 1 and the sealing frame 2. The soybean meal is then cooked in the cooking chamber 1, allowing the steam to remain inside the cooking chamber 1 and the sealing frame 2, reducing temperature fluctuations inside the cooking chamber and increasing the quality of the cooked soybean meal.
[0033] By rotating the L-shaped strip 7 through the handle 8, the horizontal bar of the L-shaped strip 7 rotates to contact the side of the vertical bar of the Chinese character strip 901, applying a squeezing force to the left and right sides of the two Chinese character strips 901, causing the two Chinese character strips 901 to drive the two L-shaped inserts 903 to open to the sides. At this time, the horizontal block of the L-shaped insert 903 moves out from the inside of the fixing groove 3, thereby releasing the fixation between the cooking chamber 1 and the sealing frame 2, and then removing the sealing frame 2 from the upper side of the cooking chamber 1, and quickly taking out the cooked soybean meal.
[0034] It should be noted that the fixing component 9 includes a Chinese character-shaped strip 901, which is slidably disposed inside the Chinese character-shaped groove 10. A compression spring 902 is fixedly disposed on the side of the horizontal bar of the Chinese character-shaped strip 901, and one end of the compression spring 902 is slidably engaged with the inside of the horizontal groove of the Chinese character-shaped groove 10.
[0035] Using the above technical solution, the Chinese-shaped strip 901 can easily move the two L-shaped inserts 903, thereby facilitating the fixing or opening of the cooking chamber 1 and the sealing frame 2 via the L-shaped inserts 903.
[0036] It should be noted that an L-shaped insert 903 is fixedly installed on the upper side of the vertical bar of the Chinese character strip 901, and the side of the horizontal block of the L-shaped insert 903 slides in conjunction with the inside of the fixing groove 3.
[0037] By adopting the above technical solution, after inserting the L-shaped insert 903 into the inside of the fixing groove 3, it is convenient to fix and seal the sealing frame 2 and the cooking chamber 1.
[0038] It should be noted that the sides of the horizontal bar of L-shaped bar 7 and the sides of the vertical bar of Chinese character bar 901 are both rounded, and the sides of the horizontal bar of L-shaped bar 7 and the sides of the vertical bar of Chinese character bar 901 are in contact.
[0039] By adopting the above technical solution, the side of the horizontal bar of the L-shaped bar 7 with rounded corners and the side of the vertical bar of the Chinese character bar 901 result in less friction when the horizontal bar of the L-shaped bar 7 contacts the vertical bar of the Chinese character bar 901.
[0040] It should be noted that the top of the cooking chamber 1 and the top of the support plate 4 are both provided with sealing strips 401, and the bottom of the sealing frame 2 and the top of the inner wall of the sealing frame 2 are both provided with sealing grooves that cooperate with the sealing strips 401.
[0041] By adopting the above technical solution, the sealing effect between the cooking chamber 1 and the sealing frame 2 can be increased through the cooperation between the sealing strip 401 and the sealing groove.
[0042] It should be noted that the top of the sealing frame 2 is provided with a long groove 201, and a handle 202 is fixedly installed inside the long groove 201.
[0043] Using the above technical solution, the sealing frame 2 can be easily moved by the pull handle 202.
[0044] It should be noted that a venting valve 203 is provided on the top of the sealing frame 2, and a temperature regulator 204 is fixedly installed on the front side of the sealing frame 2.
[0045] Using the above technical solution, the temperature inside the high-pressure cooking equipment for soybean meal can be adjusted by the temperature regulator 204, and the pressure inside the cooking equipment can be released by the air release valve 203.
[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
