Technical Field
[0001] The invention relates to the technical field of food processing, and in particular to a drum-type sterilizing device for producing pre-prepared dishes. Background Art
[0002] Pre-prepared food, also known as pre-prepared prepared food, is a dish that is packaged after the raw materials have been hygienically and scientifically processed. It can be eaten directly after a simple heating step. After the processed dishes are packaged into packaging bags and sealed, the packaged pre-prepared dishes are sterilized and then stored, which can effectively extend the storage time of pre-prepared dishes.
[0003] At present, when sterilizing pre-prepared dishes, the packaged pre-prepared dishes are generally placed directly into a sterilization chamber, and high-temperature steam is used to heat and sterilize the surface of the packaged pre-prepared dishes.

[0009] Furthermore, it also includes slide rails, cylinders and pulling rods. Two slide rails are fixed on the left side of the bottom of the outer tube, a cylinder is installed at the lower part of the support frame, a pulling rod is rotatably connected to the telescopic rod of the cylinder, and the pulling rod is clamped with the two slide rails.
[0010] Furthermore, it also includes a slide frame and a slide rod. The slide frame is symmetrically fixed on the left side of the upper part of the support frame, and the slide rod is symmetrically fixed on the right side of the cylinder cover.

[0014] Furthermore, the scraper is attached to the inner wall of the inner cylinder and can scrape off the pre-prepared dishes stuck on the inner wall.
[0015] The beneficial effects are: 1. The heating tube heats the water in the water tank, allowing steam to enter the inner cylinder, and the motor as a power source drives the inner cylinder to rotate, causing the pre-prepared food to roll, sterilizing the pre-prepared food through high-temperature steam, and also making the pre-prepared food heated evenly, improving the sterilization quality and ensuring food safety; 2.

The water injection valve 204 passes through the support frame 201. The heating pipe 203 heats the water in the water tank 202 to evaporate the water and generate steam which flows into the inner cylinder 102 through the notch and the exhaust groove 103, thereby sterilizing the prepared dishes. A motor 401 is installed on the right wall of the outer cylinder 101, and a large gear 402 is connected to the output shaft of the motor 401. A transmission shaft 404 is connected to the right side of the inner cylinder 102. The transmission shaft 404 is rotatably connected to the outer cylinder 101, and a small gear 403 meshing with the large gear 402 is fixed on the transmission shaft 404.
[0030] like Figure 1-Figure 3 As shown, the exhaust component includes a connecting frame 104, an exhaust fan 105 and a cover 106. The top of the outer tube 101 is connected to the connecting frame 104, the exhaust fan 105 is installed in the connecting frame 104, and the top of the connecting frame 104 is slidably connected to the cover 106. The hot air inside the inner tube 102 can flow into the connecting frame 104 through the exhaust groove 103 and then be discharged through the exhaust fan 105.
[0031] After the pre-prepared dishes are packaged, they need to be sterilized. During the specific operation, the pre-prepared dishes are placed in the inner cylinder 102, and then the cylinder cover 107 is turned downward to close, and then the cover 106 is pushed to the left to close. The external pipe is on the water injection valve 204, and water is injected into the water tank 202. After the end, the outer cylinder 101 is turned downward to be straightened, and the motor 401 and the heating tube 203 are turned on.

After the sterilization is completed, the motor 401 and the heating tube 203 are turned off to stop the inner cylinder 102 from rotating. The outer cylinder 101 can be turned upward and tilted back to the initial angle, and then the cover 106 is moved to the right to open, and the exhaust fan 105 is turned on, so that the exhaust fan 105 discharges the hot air in the inner cylinder 102 outward through the exhaust groove 103. The staff can also turn the cylinder cover 107 upward to open it to speed up the discharge of the hot air in the inner cylinder 102. After the hot air is discharged, the exhaust fan 105 is turned off, and the sterilized pre-prepared dishes can be taken out. In this way, the sterilization of a batch of pre-prepared dishes is completed. The motor 401 is used as a power source to drive the inner cylinder 102 to rotate, which can make the pre-prepared dishes heated more evenly, improve the sterilization quality, and ensure food safety.
[0032] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5 As shown, it also includes a slide rail 301, a cylinder 302 and a pulling rod 303. Two slide rails 301 are fixed to the left side of the bottom of the outer tube 101, and a cylinder 302 is installed at the lower part of the support frame 1. The pulling rod 303 is rotatably connected to the telescopic rod of the cylinder 302, and the pulling rod 303 is clamped with the two slide rails 301.
[0033] The telescopic rod of the cylinder 302 is initially in an extended state. When the outer cylinder 101 needs to be rotated downward for adjustment, the telescopic rod of the cylinder 302 is controlled to retract, driving the pulling rod 303 to move to the right, so that the pulling rod 303 pulls the slide rail 301 and the outer cylinder 101 to rotate downward, and the angle of the outer cylinder 101 can be adjusted. The extension of the telescopic rod of the cylinder 302 will push the pulling rod 303 to move to the left, so that the pulling rod 303 pushes the slide rail 301 and the outer cylinder 101 to rotate upward for adjustment. After the angle of the outer cylinder 101 is adjusted, the cylinder 302 can be closed. In this way, there is no need to manually rotate the outer cylinder 101 for adjustment, which provides convenience for the staff.
[0034] like Figure 8As shown, it also includes a slide frame 501 and a slide rod 502. The slide frame 501 is symmetrically fixed to the left side of the upper part of the support frame 1, and the slide rod 502 is symmetrically fixed to the right side of the cylinder cover 107. The two slide rods 502 are slidably connected to the slide frame 501 on the same side.
[0035] like Fig. 9 and Fig.10 As shown, it also includes a limit block 601, a pull rope 602 and a reset spring 603. The limit block 601 is symmetrically fixed on the front and back left side of the upper part of the outer cylinder 101, and the pull rope 602 is connected to the front and back sides of the cover 106. The other ends of the pull rope 602 are respectively connected to the front and back sides of the cover 106. The pull ropes 602 all pass through the limit block 601 on the same side. When the cylinder cover 107 is closed, the pull rope 602 will be pulled, and then the cover 106 will be closed. A reset spring 603 is connected between the cover 106 and the connecting frame 104.
[0036] Initially, both the lid 106 and the cylinder cover 107 are in an open state. After the prepared dish is placed in the inner cylinder 102, the air cylinder 302 is directly controlled to drive the outer cylinder 101 to rotate downward and align. The outer cylinder 101 drives the cylinder cover 107 and the slide bar 502 to rotate downward. The slide bar 502 slides along the slide slot frame 501. Due to the limit of the slide slot frame 501, the slide bar 502 drives the cylinder cover 107 to rotate downward along the outer cylinder 101 to close the cylinder cover 107. The rotation and closing of the cylinder cover 107 will pull the pull rope 602, so that the pull rope 602 pulls the lid 106 to move to the left and close, and the reset spring 603 is compressed, so that the cylinder cover 107 and the lid 107 are automatically closed. 6 is closed, eliminating the trouble of manual operation and thus improving work efficiency. After the sterilization of the pre-prepared dishes is completed, the cylinder 302 drives the outer cylinder 101 to rotate and tilt upward, and the outer cylinder 101 will rotate with the cylinder cover 107 and the slide bar 502, and the slide bar 502 slides along the slide slot frame 501, thereby pushing the cylinder cover 107 to rotate upward along the outer cylinder 101 to open. The rotation of the cylinder cover 107 will loosen the pull rope 602, so that the lid 106 moves to the right side to open under the resetting action of the resetting spring 603, and pulls the pull rope 602 to reset. In this way, after the sterilization of the pre-prepared dishes is completed, the cylinder cover 107 and the lid 106 are automatically opened, so that the hot air in the inner cylinder 102 is convenient to discharge.
[0037] like Fig.11 As shown, it also includes a scraper 701 and a buffer spring 702. The scraper 701 is slidably connected to the outer cylinder 101, and two buffer springs 702 are connected between the scraper 701 and the outer cylinder 101. The scraper 701 is attached to the inner wall of the inner cylinder 102 and can scrape off the pre-prepared dishes stuck on the inner wall.
[0038] When the inner cylinder 102 rotates with the pre-prepared dishes for sterilization, the pre-prepared dishes may stick to the inner wall of the inner cylinder 102 due to the steam. When the inner cylinder 102 rotates, the scraper 701 sticks to the inner wall and can scrape off the pre-prepared dishes stuck to the inner wall of the inner cylinder 102. The buffer spring 702 buffers the scraper 701, thus preventing the pre-prepared dishes from sticking to the inner wall of the inner cylinder 102 and affecting the sterilization effect.
