[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a fresh-keeping tofu production system. Figure 1-Figure 5 As shown, it includes a tipping machine 1, which is connected to a packaging machine 3 via a conveying device 2. A belt conveyor 4 is arranged at the outlet of the packaging machine 3. The output end of the belt conveyor 4 is connected to a sterilizer 5. The outlet of the sterilizer 5 is connected to a cooler 6. The outlet of the cooler 6 is connected to a flip air dryer 7. A material receiving frame 8 is arranged below the outlet of the flip air dryer 7 for receiving materials.

[0023] In this embodiment, a stirring device and an ultraviolet sterilization device are provided in the tipping machine 1. Pure water is introduced into the tipping machine 1. The stirring device is used to fully dissolve the added edible salt and the ultraviolet sterilization device is turned on to perform preliminary sterilization on the tofu product placed in the tipping machine 1.

[0024] Specifically, the conveying device 2 includes an inclined conveyor belt and a driving motor. A hair dryer is arranged above the conveyor belt. The driving motor drives the conveyor belt to transport the tofu product, and the hair dryer is used to remove excess moisture from the tofu product.

[0025] Furthermore, the packaging machine 3 includes an automatic weighing system, an automatic loader, a sealing machine and a control system. The control system controls the front-end product to perform automatic weighing, loading and sealing operations. This is the conventional structure of the existing packaging machine 3 and will not be described in detail here.

[0026] Furthermore, a bubbler is provided at the bottom of the cooler 6 for bubbling to extend the retention time of the product in the cooler and allow the product to be fully cooled.

[0027] Furthermore, the tipping machine 1 includes a shell 11 for holding brine, and a plurality of tipping buckets 12 driven by a motor 13 to flip. The tipping buckets 12 and the motor 13 constitute a stirring device. The interior of the tipping machine 1 is filled with brine, and an ultraviolet lamp tube 14 is arranged in the brine. The ultraviolet lamp tube 14 is used to sterilize the brine. A plurality of ultraviolet lamp tubes 14 constitute an ultraviolet sterilization device. A mesh 121 is arranged on the tipping bucket 12. After the tofu placed on the tipping bucket 12 is immersed in the brine for a certain period of time, the tipping bucket 12 rotates to send the tofu into the next tipping bucket 12, and the above steps are repeated until the tofu with sufficient sterilization time is sent to the conveying device.

[0028] Furthermore, the flip dryer 7 includes a plurality of fans 71 with air outlets facing downward and a conveying device 72. The wind from the fans 71 dries the surface of the tofu packaging. The conveying device 72 includes a plurality of conveyor belts arranged in sequence. Each conveyor belt is inclined and has a certain height difference. When the tofu enters the next conveyor belt from one conveyor belt, one side will be flipped due to the height difference, so that the fan can dry both sides of the packaging.

[0029] When the fresh tofu production system of the utility model is used, first, the tipping machine 1 is used as the starting link of the production line, and is filled with salt water and equipped with an ultraviolet sterilization device. When pure water is introduced into the tipping machine 1 and an appropriate amount of edible salt is added, the stirring device will be started to fully dissolve the salt in the water to form a salt water with a certain concentration. At the same time, the ultraviolet sterilization device is also turned on to perform preliminary sterilization treatment on the salt water.

[0030] Subsequently, the formed tofu product is placed in the tipping machine 1 and soaked in salt water. During the soaking process, the salt water sterilizes the tofu, and the ultraviolet sterilization device performs a preliminary sterilization treatment. After soaking for a certain period of time, the tipping bucket 12 will rotate under the drive of the motor 13, and the tofu will be sent to the next tipping bucket 12 to continue soaking and sterilization. This process will be repeated until the tofu is soaked in the salt water for a sufficient time to achieve the desired sterilization effect.

[0031] The tofu that has undergone preliminary sterilization is then transported to the conveyor 2. The conveyor belt of the conveyor 2 is tilted and equipped with a fan on top. When the tofu is transported on the conveyor belt, the fan can remove excess moisture on its surface to prepare for the subsequent packaging process.

[0032] Next, the tofu is sent to the packaging machine 3 for automatic weighing, feeding and sealing. The control system of the packaging machine 3 will accurately control the weight of each tofu to ensure the standardization of the product. The sealed tofu is conveyed by the belt conveyor 4 and sent to the sterilizer 5 for high-temperature water bath sterilization. This process can further kill the microorganisms in the tofu and extend its shelf life.

[0033] The sterilized tofu then enters the cooling machine 6 for rapid cooling. The bubbler at the bottom of the cooling machine 6 can generate bubbles to fully contact the cooling water and fully cool the tofu. This process can quickly reduce the temperature of the tofu and prevent it from deteriorating due to high temperature.

[0034] Finally, the cooled tofu is sent to the tumble dryer 7 for air drying. The fan 71 of the tumble dryer 7 blows out air to dry the surface of the tofu package. At the same time, the conveyor 72 is tilted so that the tofu turns over when it enters the next conveyor from one conveyor belt, so that the fan can dry both sides of the package. The air-dried tofu will eventually be sent to the receiving frame 8 to complete the entire fresh-keeping process.

[0035] Finally, it should be noted that the electronic components of the conveying device 2, packaging machine 3, belt conveyor 4, cooler 6, tumble dryer 7, etc. in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
