Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a high-temperature sterilization food storage tank. Background Technology

[0002] In the food processing industry, high-temperature sterilization food sterilization tanks are commonly used equipment. These tanks work by placing sealed packaged food in baskets, then pushing stacked baskets into the sterilization tank via guide rails for high-temperature sterilization. However, existing sterilization tanks have several problems: poor stability when the baskets are stacked, lacking an effective positioning and locking structure, making them prone to shaking or even tipping over during operation; during high-temperature sterilization, the sealed food packaging bags easily bulge due to the high temperature, and when the bulge reaches a certain extent, the bags may break. After sterilization, each food item needs to be checked for damage, and there is no indicator structure to show when the packaging bags bulge, severely impacting work efficiency. To solve these problems, this invention provides a high-temperature sterilization food sterilization tank.

[0003] Therefore, it is essential to invent an intelligent high-temperature sterilization device for food processing. Utility Model Content

The second support plate is slidably connected to two second guide rails through the ball bearings, and a second pusher is fixed to one side of the top surface of the second support plate.

[0008] Preferably, the basket includes a rectangular frame, with a first connecting rod fixed at each of the four corners of the bottom of the rectangular frame. The bottom ends of the four first connecting rods are fixed with the same rectangular cover plate, the size of which matches the size of the rectangular frame. Several spring cylinders are evenly fixed at the bottom of the rectangular frame, and a T-shaped sliding rod is slidably disposed within each spring cylinder. The bottom end of the T-shaped sliding rod extends out of the spring cylinder. The lower ends of the several spring cylinders are provided with the same pressure plate. The bottom end of the T-shaped sliding rod is fixedly connected to the top end of the pressure plate. A spring is disposed between the top end of the T-shaped sliding rod and the top end of the spring cylinder. The size of the pressure plate is smaller than the size of the rectangular frame, allowing the pressure plate to be inserted into the rectangular frame of another basket.

[0009] Preferably, the locking structure includes a U-shaped handle, which is fixed to the side wall of a rectangular cover plate. A pull rod is provided inside the U-shaped handle, and guide rods are symmetrically arranged through the pull rod. A stop block is fixed to one end of the guide rod, and the other end of the guide rod is fixedly connected to the inner wall of the U-shaped handle. A first spring is fixed between the pull rod and the inner wall of the U-shaped handle, and the first spring is sleeved on the guide rod. Second connecting rods are symmetrically fixed to the bottom end of the pull rod, and the same positioning block is fixed to the side wall of the two second connecting rods. A first positioning groove and a second positioning groove for the positioning block to be inserted are respectively opened on both sides of the rectangular frame and both sides of the rectangular frame.

[0010] Preferably, the prompting structure includes a fixing plate and a toothed plate fixed to the side wall of a rectangular frame. The toothed plate is located at the upper end of the fixing plate, and a plurality of positioning toothed grooves are formed on the top surface of the toothed plate. A first square rod is transversely inserted through the fixing plate. The first square rod is slidably connected to the fixing plate. A limit block is fixed to one end of the first square rod, and a first trapezoidal block is fixed to the other end of the first square rod. A second spring is fixed between the first trapezoidal block and the fixing plate. The second spring is sleeved on the first square rod. A second trapezoidal block is attached to the inclined surface of the first trapezoidal block. An L-shaped connecting plate is fixed to the bottom end of the second trapezoidal block. The other end of the L-shaped connecting plate is fixedly connected to the top surface of the pressure plate. An observation hole is formed on the side wall of the first trapezoidal block. A white and red indicator block are provided between the side walls of the rectangular frame. The white indicator block can be observed through the observation hole in the initial state of the second trapezoidal block. Both the white and red indicator blocks are fixed to the side walls of the rectangular frame. A second square rod is vertically inserted through the first trapezoidal block. The second square rod is slidably connected to the first trapezoidal block. A retaining ring is fixed at the top of the second square rod. A limit ring is fixedly fitted on the second square rod. A third spring is fixed between the top of the limit ring and the bottom of the first trapezoidal block. The third spring is fitted on the second square rod. A chamfer is opened on one side edge of the bottom end of the second square rod. When the baskets are stacked, the chamfered part of the bottom end of the second square rod can be inserted into the positioning tooth groove on the toothed plate of the basket below it.

[0011] Preferably, through holes are evenly provided on the outer wall of the rectangular frame and on the pressure plate.

[0012] Compared with existing technologies, the beneficial effects of this utility model are: This invention, through its indicator structure, allows for effective alerts during high-temperature sterilization. If a food bag in one of the baskets expands excessively, the inflated bag pushes against the pressure plate of the upper basket. As the pressure plate is pushed upwards, the L-shaped connecting plate simultaneously moves the second trapezoidal block upwards. This upward movement of the second trapezoidal block compresses the first trapezoidal block, causing it to move towards the fixed plate. Simultaneously, the first trapezoidal block moves the second square rod, which then enters a corresponding positioning groove, preventing the first trapezoidal block from resetting under the action of the second spring. When the food bag expands excessively, the observation hole of the first trapezoidal block aligns with the red indicator block. Thus, when sterilization is complete, the red indicator block on the upper basket of this basket is clearly visible, indicating that the food bag in the lower basket of the basket displaying the red indicator block has expanded excessively, effectively providing an alert. Furthermore, the locking structure securely locks the stacked baskets, preventing them from shaking during high-temperature sterilization. Attached Figure Description

A chamfer is opened on one side edge of the bottom end of the second square rod 29. When the baskets 12 are stacked, the chamfered part at the bottom end of the second square rod 29 can be inserted into the positioning tooth groove on the toothed plate 22 of the basket 12 below it.

[0021] The rectangular frame 12-1 has through holes evenly distributed on its outer wall and on its pressure plate 17.

[0022] Working principle; In use, the first basket 12 is lifted using the U-shaped handles 18 on both sides and placed on the rectangular frame 11 of the placement structure. During placement, the pull rod 37 is hooked with a finger. After placing the basket 12 on the rectangular frame 11, the finger is released from the pull rod 37. At this time, the positioning block 42 will insert into the second positioning groove 35 opened on the side wall of the rectangular frame 11, thus locking the first basket 12 on the rectangular frame 11. After the basket 12 is placed on the rectangular frame 11, the rectangular cover plate 14 will cover the upper edge of the rectangular frame 11, further preventing the basket 12 from falling off. 2. After shaking it around, place the food flat into the rectangular frame 12-1 of the first basket 12. The food should be placed below two-thirds of the height of the rectangular frame 12-1. The upper third of the space is reserved for the insertion space of the pressure plate 17 of the upper basket 12. After the bottom basket 12 is filled with food, lift the second basket 12 using the U-shaped handles 18 on both sides and place it on the rectangular frame 12-1 of the first basket 12. During the placement, hook the lever 37 with your fingers. After placing the basket 12 on the rectangular frame 12-1 of the first basket 12, release your fingers from the lever 37. The positioning block 42 will be inserted into the first positioning groove 19 opened on the side wall of the rectangular frame 12-1, so that the second basket 12 will be locked on the first basket 12. After the second basket 12 is placed on the first basket 12, the rectangular cover plate 14 of the second basket 12 will cover the upper edge of the rectangular frame 12-1 of the first placed basket 12, further preventing the two stacked baskets 12 from shaking. Then, in the same way, the remaining baskets 12 are stacked in sequence according to the above steps. When stacked to the end, no food is put in the rectangular frame 12-1 of the top basket 12, because there is no other food in the top basket 12. The basket 12 is used as a cover. After the last basket 12 is stacked, the basket moving cart is pushed by the first pusher 8 to move the placement structure and the basket 12 stacked on top of it to one side of the sterilization storage tank body 1. The sealing door 2 of the sterilization storage tank body 1 is opened so that the second guide rail 6 of the basket moving cart is aligned with the first guide rail 4 inside the sterilization storage tank body 1. Then, the placement structure is pushed by the second pusher 10 so that the placement structure, along with the basket 12 stacked on top of it, enters the sterilization storage tank body 1. Then, the basket moving cart is opened and the sealing door 2 is closed. The food in the basket 12 is then sterilized at high temperature inside the sterilization storage tank body 1.During the high-temperature sterilization process, if the food sealing bag inside the rectangular frame 12-1 of a basket 12 expands excessively, the expanded sealing bag will push against the pressure plate 17 on the upper basket 12. When the pressure plate 17 is pushed upward, it simultaneously drives the second trapezoidal block 21 to move upward through the L-shaped connecting plate 20. During the upward movement of the second trapezoidal block 21, it squeezes the first trapezoidal block 27 to move towards the fixing plate 23. When two adjacent baskets 12 are stacked, the chamfered bottom end of the second square rod 29 on the upper basket 12 will insert into the positioning tooth groove on the toothed plate 22 on the lower basket 12. Thus, as the first trapezoidal block 27 is pushed by the second trapezoidal block 21, the first trapezoidal block 27 will simultaneously drive the second square rod 29 to move towards the fixing plate 23. As the second square rod 29 moves, it enters the corresponding positioning groove, preventing the first trapezoidal block 27 from resetting under the action of the second spring 26. When the food sealing bag expands excessively, the observation hole 28 of the first trapezoidal block 27 will correspond to the red indicator block 34. Thus, when the sterilization work is completed, the red indicator block 34 displayed on the upper basket 12 of this basket 12 can be clearly observed after pulling out the placement structure. This indicates that the food in the lower basket 12 of the basket 12 displaying the red indicator block 34 has experienced excessive expansion of the food sealing bag, effectively serving as an indicator. When the upper basket 12 is moved, the second square rod 29 will disengage from the toothed plate 22 on the lower basket 12 and automatically reset under the action of the second spring 26.
