Description

Technical Field

[0001] The present invention relates to a disinfection method for food material packaging finished products. Background Art

[0002] Food material packaging finished products are made by filling and sealing products in packaging containers (usually flexible packaging containers, glass bottles, etc.), and they usually use the pasteurization method for sterilization. However, the existing disinfection production line is a disinfection device for food material packaging finished products, which usually uses a chain plate conveying mechanism to convey food material packaging finished products through a hot water tank and a cold water tank in sequence, and then uses the flipping of the chain plate to pour out the food material packaging finished products.

[0003] However, the applicant found that the traditional disinfection method uses a chain conveyor mechanism to convey the finished food material packaging. If the finished food material packaging is a small-sized sheet-shaped soft packaging container, due to the large contact surface between its surface and the chain plate of the chain conveyor mechanism, it is easy for some of the finished food material packaging products to be adsorbed on the chain plate during the disinfection process and difficult to detach from the chain plate by their own gravity, causing great trouble to normal production and seriously affecting work efficiency. In addition, the chain conveyor mechanism usually has a plurality of conveying troughs connected in sequence. These sheet-shaped soft packaging containers located in these conveying troughs are easy to float in the water and cannot follow the movement of the conveying trough. Therefore, the conveying trough is usually very deep, and the number of sheet-shaped soft packaging containers that can be carried is small, and it is difficult to improve work efficiency; if the finished food material packaging is a large-sized soft packaging container, glass bottle, plastic bottle, etc., it is easy to cause these packaging containers to be damaged due to collision during the dumping process. In addition, since the chain plate is horizontally unfolded, the finished food material packaging is prone to uneven distribution when dumped on the chain plate, resulting in accumulation of finished food material packaging products in some areas, while there are no finished food material packaging products in some areas, resulting in low work efficiency and difficulty in improving, and poor sterilization effect. The above problems lead to that no matter what kind of food material packaging finished product, it can only be transported on the surface of the chain plate, which makes the equipment occupy a large area, high manufacturing cost and use cost, low utilization rate of hot water tank and cold water tank, and the chain plate conveying mechanism needs frequent maintenance and repair, which is difficult to replace. The plastic chain plate conveying mechanism cannot be disassembled, and it is difficult to clean the bottom of the hot water tank and cold water tank. After a period of work, it cannot meet the sanitation requirements of production. Moreover, since it needs to be heated by hot water and cooled by cold water in turn, the structure of the plastic parts is easy to be damaged quickly due to long-term alternation of thermal expansion and contraction. The chain plate conveying mechanism made of stainless steel is prone to large gaps between components after being in a state of alternating thermal expansion and contraction for a long time, which affects normal transportation. It is easy for the finished food material packaging (sheet-shaped soft packaging container) to fall below through the gap or the finished food material packaging is stuck or even broken by the gap. Moreover, no matter what kind of material the chain plate conveying mechanism is made of, after long-term work, there is a problem that the gear and the chain plate are not well matched and difficult to adjust. Moreover, in the existing production line using chain conveyor mechanism, the equipment can only be extended on the ground, and the space utilization rate is low, so that the floor space of the production line is too large.

[0004] In order to solve the above problems, the applicant has improved the prior art, see the Chinese patent document with announcement number CN 117049171A and title “Pasteurization production line for packaged food products”.

[0005] However, the applicant found that this method has the following problems: 1. The hot water tank and the cold water tank are arranged in sequence along the horizontal direction, which is consistent with the design of the production line using a chain plate conveying mechanism. However, it has a large floor area and cannot be reduced. Moreover, such a design makes the box return channels arranged above or below occupy a large amount of space, greatly increasing the costs of equipment and site. In addition, the water dripping from the finished product storage box will pollute the working environment and affect the normal progress of production. 2. The finished product storage box with a sealed cover is used to store the food material packaging finished products. Since the sealed cover will restrict the upward movement of the food material packaging finished products to leave the finished product storage box, in the actual production process, a large amount of time and force are required to achieve the purpose of pressing the finished product storage box into the water, which is time-consuming and laborious. 3. The wheels at the bottom of the finished product storage box move without direction on the bottom surface of the hot water tank and the cold water tank. In the actual production process, adjacent finished product storage boxes will collide, and the finished product storage boxes with uncertain directions will affect the force transmission. Because all the finished product storage boxes are in water, the mutual influence becomes larger, resulting in the manipulator needing to vigorously push the finished product storage boxes forward in sequence. The speed of the finished product storage boxes is very low and difficult to increase.

[0006] In summary, this technology has disadvantages such as unreasonable structure, large equipment occupancy space, large floor area, high energy consumption, and low working efficiency, making this method difficult to be accepted by producers and it is necessary to improve it. Summary of the Invention

[0007] The object of the present invention is to provide a disinfection method for food material packaging finished products, which can greatly reduce the consumed energy, floor area, and occupied space. The adopted technical solution is as follows: A disinfection method for food material packaging finished products successively includes the following steps: a. Sending the food material packaging finished products into the hot water tank for hot water disinfection; b. Taking out the food material packaging finished products from the hot water tank and sending them into the cold water tank for cooling; c. Taking out the food material packaging finished products from the cold water tank and sending them away. It is characterized in that: before processing, the food material packaging finished products are stored in a small car that allows water to enter and exit. In step a, the small car successively moves from the entrance to the exit along the bottom surface of the hot water tank, allowing the hot water in the hot water tank to enter and exit the small car and disinfect all the food material packaging finished products in the small car. In step b, the small car successively moves from the entrance to the exit along the bottom surface of the cold water tank, allowing the cold water in the cold water tank to enter and exit the small car and cool all the food material packaging finished products in the small car. The hot water tank is located above the cold water tank, and the outlet of the hot water tank is located above the inlet of the cold water tank. The bottom surface of the hot water tank is provided with a track, and the bottom surface of the cold water tank is provided with a track. The bottom surface of the trolley is provided with track wheels that can cooperate with the tracks. When the trolley is placed in the hot water tank or the cold water tank, the track wheels on the bottom surface of the trolley are sleeved on the tracks and roll along the tracks; Outside the outlet of the cold water tank, there is a trolley return track. The end of the trolley return track is located below the inlet of the hot water tank. After the trolley empties the disinfected food material packaging finished products at this place, it is loaded with the food material packaging finished products to be disinfected and lifted into the inlet of the hot water tank; The movement of the trolley in the hot water tank is achieved by pushing the trolley at the inlet of the hot water tank and letting this trolley drive the trolleys in front of it in turn, so as to realize the movement of all trolleys; The movement of the trolley in the cold water tank is achieved by pushing the trolley at the inlet of the cold water tank and letting this trolley drive the trolleys in front of it in turn, so as to realize the movement of all trolleys.

[0008] In a preferred solution, the water depth of the hot water tank is less than or equal to the height of the trolley, and the water depth of the cold water tank is less than or equal to the height of the trolley.

[0009] In a preferred solution, the removal, placement, and pushing of the trolley are all completed by a manipulator.

[0010] The beneficial effects of the present invention compared with the prior art are as follows: Since the hot water tank is located above the cold water tank, it can effectively utilize the space, reduce the occupied space and floor area of the equipment, effectively avoid the heat transfer of the hot water tank to the cold water tank and affect the cooling effect of the cold water tank, greatly reduce the water flowing to the outside during the transfer of the trolley, and reduce the adverse impact on the environment; The water depths of the hot water tank and the cold water tank are designed to be less than the height of the trolley, so that the trolley can avoid the food material packaging finished products leaving the trolley without a sealing cover restricting the food material packaging finished products. In this way, the resistance of removing, placing, and pushing the trolley will be greatly reduced, the consumed energy can be effectively reduced, and the working efficiency can be greatly improved; The structure of the trolley is improved, and the tracks are matched with the track wheels, so that multiple trolleys can move smoothly and uniformly along the tracks on the bottom surface of the hot water tank and the bottom surface of the cold water tank in turn, enabling the producer to adjust the speed of the trolley according to needs, so as to achieve the purpose of controlling the disinfection and cooling speed and effect; And since the removal, placement, and pushing of the trolley are all completed by a manipulator, these operations can be automated, effectively improving the energy utilization rate and greatly enhancing the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic structural diagram of an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] Such as Figure 1As shown in the figure, the disinfection method for the finished product of food material packaging in an embodiment of the present application sequentially includes the following steps: a. Send the finished product of food material packaging into the hot water tank 2 for hot water disinfection; b. Take out the finished product of food material packaging from the hot water tank 2 and send it into the cold water tank for cooling; c. Take out the finished product of food material packaging from the cold water tank 3 and send it away; Before processing, store the finished product of food material packaging in the trolley 4 that allows water to enter and exit; In step a, the trolley 4 moves along the bottom surface of the hot water tank 2 from the entrance to the exit in sequence, allowing the hot water in the hot water tank 2 to enter and exit the trolley 4 and disinfect all the finished products of food material packaging in the trolley 4; In step b, the trolley 4 moves along the bottom surface of the cold water tank 3 from the entrance to the exit in sequence, allowing the cold water in the cold water tank 3 to enter and exit the trolley 4 and cool all the finished products of food material packaging in the trolley 4; The hot water tank 2 is located above the cold water tank 3, and the outlet of the hot water tank 2 is located above the entrance of the cold water tank 3; The bottom surface of the hot water tank 2 is provided with a track, the bottom surface of the cold water tank 3 is provided with a track, and the bottom surface of the trolley 4 is provided with track wheels that can cooperate with the track. When the trolley 4 is placed in the hot water tank 2 or the cold water tank 3, the track wheels on the bottom surface of the trolley 4 are sleeved on the track and roll along the track; There is a trolley return track 6 outside the outlet of the cold water tank 3. The end of the trolley return track 6 is located below the entrance of the hot water tank 2. After the trolley empties the disinfected finished products of food material packaging at this place (the end of the trolley return track 6), it is loaded with the finished products of food material packaging to be disinfected and lifted into the entrance of the hot water tank 2; The movement of the trolley 4 in the hot water tank 2 is achieved by pushing the trolley 4 at the entrance of the hot water tank 2 and allowing this trolley 4 to drive the trolleys 4 in front of it in sequence, so as to realize the movement of all trolleys 4; the movement of the trolley 4 in the cold water tank 3 is achieved by pushing the trolley 4 at the entrance of the cold water tank 3 and allowing this trolley 4 to drive the trolleys 4 in front of it in sequence, so as to realize the movement of all trolleys 4.

[0013] Since the hot water tank 2 is located above the cold water tank 3, and the outlet of the hot water tank 2 is above the inlet of the cold water tank 3, the entire line is folded in half, which can effectively utilize the space, reduce the floor area of the equipment, and greatly reduce the distance from the outlet of the cold water tank 3 to the inlet of the hot water tank 2, facilitating the emptying of the trolley and loading it with food material packages and sending them to the inlet of the hot water tank 2, greatly reducing the space occupied by the trolley return track 6 (equivalent to the box return channel of CN 117049171 A), and effectively preventing the heat of the hot water tank 2 from being transferred to the cold water tank 3 and affecting the cooling effect of the cold water tank 3. Moreover, this design greatly reduces the water flowing out to the outside during the transfer of the trolley (because the water flowing out of the trolley 4 from the hot water tank 2 will fall into the cold water tank 3), reducing the adverse impact on the environment. The food material packages are stored in the trolley 4 that allows water to enter and exit. Therefore, the food material packages can not only make full use of the space inside the trolley 4, but also be protected by the trolley 4 during the entire disinfection process. The trolley 4 moves along the bottom surface of the hot water tank 2 and the bottom surface of the cold water tank 3, enabling the producer to adjust the speed of the trolley 4 as needed, thereby achieving the purpose of controlling the disinfection, cooling speed, and effect. The cooperation between the track and the track wheels not only enables the trolley 4 to move along the track in sequence, but also facilitates the producer to push the trolley 4, allowing the trolleys 4 on the same track to transmit power in sequence and move smoothly in order.

[0014] As Figure 1 shown, in an alternative embodiment of the present application, the water depth of the hot water tank 2 is less than or equal to the height of the trolley 4, and the water depth of the cold water tank 3 is less than or equal to the height of the trolley 4. Such a design enables the trolley 4 to avoid the food material packages leaving the trolley 4 without a sealing cover, thus significantly reducing the resistance to taking out, putting in, and pushing the trolley 4, effectively reducing the energy consumption, and greatly improving the work efficiency.

[0015] As Figure 1 shown, in an alternative embodiment of the present application, the hot water tank 2 and the cold water tank 3 are respectively installed on the frame 1.

[0016] In step c, after taking out the trolley 4, the food material packages in the trolley 4 are taken out manually or by mechanical equipment.

[0017] As Figure 1 shown, in an alternative embodiment of the present application, the taking out, putting in, and pushing of the trolley 4 are all completed by the manipulator 5. Therefore, these operations can be automated, effectively improving the energy utilization rate, avoiding energy waste, and greatly enhancing the work efficiency. Only a small number of engineers are required to monitor the production, significantly reducing the labor cost.

[0018] As Figure 1As shown in the figure, in an alternative embodiment of the present application, the manipulators 5 are used in pairs, and a pair of manipulators 5 used in pairs are respectively arranged on the front and rear sides of the frame and are arranged opposite to each other. Such a design facilitates the operation of the manipulator 5 on the trolley 4, avoids uneven force on the trolley 4, and enables the trolley 4 to move more stably and accurately.

[0019] As Figure 1 shown in the figure, in an alternative embodiment of the present application, a pair of manipulators 5 are arranged between the outlet of the hot water tank 2 and the inlet of the cold water tank 3, a pair of manipulators 5 are arranged at the outlet of the cold water tank 3, and a pair of manipulators 5 are arranged at the inlet of the hot water tank 2.

[0020] In an alternative embodiment of the present application, the side wall and the bottom panel of the trolley 4 are both covered with through holes. Such a design facilitates the entry and exit of water from the trolley 4.

[0021] In order to avoid the pollution of the environment by the water flowing out of the trolley 4 and increase the cost of the producer (cleaning, recycling, discharging wastewater, and in addition, water needs to be replenished), in an alternative embodiment of the present application, a recovery water tank is provided at the lower part of the frame 1. Since there is a large amount of flowing water only below the trolley return track 6, the recovery water tank can be arranged below the trolley return track 6. Such a design can effectively and automatically recover the water flowing out of the trolley 4 for reuse, not only reducing environmental pollution, but also saving water consumption and labor for cleaning.

[0022] The following combines Figure 1 to introduce the working process: 1. Load the packaged finished food materials into the empty trolley 4 located at the end of the trolley return track 6; 2. A pair of manipulators 5 on the right side of the frame 1 lift the above-mentioned trolley 4 from the end of the trolley return track 6 and place it into the inlet of the hot water tank 2, and then push the trolley 4 a certain distance towards the outlet of the hot water tank 2 (i.e., the left side of the frame); 3. A pair of manipulators 5 on the left side of the frame 1 take out the trolley (which has completed the disinfection work) located at the outlet of the hot water tank 2 and place it into the inlet of the lower cold water tank 3, and then push the trolley 4 a certain distance towards the outlet of the cold water tank 3 (i.e., the right side of the frame); 4. A pair of manipulators 5 at the outlet of the cold water tank 3 take out the trolley (which has completed the cooling work) located at the outlet of the cold water tank 3 and send it onto the trolley return track 6 to push the trolley 4 to the end of the trolley return track 6; 5. For the trolley 4 moving to the end of the trolley return track 6 (i.e., below the inlet of the hot water tank 2), the packaged finished food materials inside are taken out manually or by automated equipment, leaving the empty trolley 4.

[0023] In this way, the disinfection work of the packaged finished food materials can be continuously completed.

[0024] Since the present application improves the method, the structure of the trolley, the structure of the hot water tank, and the structure of the cold water tank are improved, and the positions between the hot water tank and the cold water tank, the water depth of the hot water tank, the water depth of the cold water tank, etc. are improved. These improvements are all technologies never used in the art. They cooperate with each other to optimize the structure of the equipment, greatly reduce the occupied space and floor area of the equipment, and effectively reduce the consumed energy, thus greatly improving the working efficiency.

[0025] In addition, it should be noted that for the specific embodiments described in this specification, the names of their respective parts, etc. can be different. Any equivalent or simple changes made according to the structure, features, and principles described in the inventive concept of this invention patent are included in the protection scope of this invention patent. Those skilled in the technical field to which this invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, as long as they do not deviate from the structure of this invention or exceed the scope defined by this claim book, they should all fall within the protection scope of this invention.
