Description

Technical Field

[0001] This utility model relates to the field of food processing machinery technology, specifically to a double-spiral quick-freezing machine with an auxiliary feeding structure. Background Technology

[0002] In the food processing and freezing industry, blast freezers are common equipment used to rapidly lower the temperature of food to maintain its freshness and extend its shelf life. Traditional blast freezers typically employ a single-spiral conveyor belt design, which suffers from inefficiency when handling large quantities or multiple types of materials. Because a single-spiral conveyor belt can only process one type of material at a time, this limits the equipment's capacity, significantly impacting production efficiency, especially when processing multiple different materials simultaneously or large quantities of the same type of material.

[0003] Furthermore, single-spiral conveyor belts may cause materials to interfere with each other during transport, affecting the uniformity of freezing and consequently impacting the quality of the final product. At the same time, traditional freezers have a low degree of automation, requiring significant manual operation, which not only increases labor intensity but also reduces production consistency and reliability. Utility Model Content

[0004] The purpose of this invention is to provide a double-spiral quick-freezing machine with an auxiliary feeding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-spiral quick-freezing machine with an auxiliary feeding structure, the quick-freezing machine comprising a frame and a body, wherein the body is mounted on the frame;

[0006] Inside the machine body, there is a rotating shaft with a first spiral conveyor belt and a second spiral conveyor belt mounted on it. These two spiral conveyor belts are arranged alternately. The rotating shaft is driven by a motor to realize the rotational movement of the conveyor belts.

[0007] The machine body has two feed inlets at the top, two in total, which correspond to the feed ends of the first and second spiral conveyor belts, respectively. Simultaneously, the machine body also has two discharge outlets at the top, two in total, which correspond to the discharge ends of the first and second spiral conveyor belts, respectively.

[0008] Feed conveyor belts are installed at the inlet ends of both the first and second spiral conveyor belts to facilitate the smooth entry of materials. Similarly, discharge conveyor belts are installed at the outlet ends of both the first and second spiral conveyor belts to ensure the smooth output of materials.

[0009] The machine body is also equipped with a refrigeration device, which is connected to the machine body, so that the materials on the conveyor belt can be effectively frozen.

[0010] More specifically, the bottom of the frame is designed with flexible feet, which can provide a certain degree of cushioning to reduce the impact of vibrations generated by the machine during operation on the ground.

[0011] Furthermore, the machine body is also equipped with a controller, which is electrically connected to the feeding conveyor belt, the discharging conveyor belt, the freezing equipment and the motor, so that the working status of the entire quick-freezing machine can be centrally controlled and managed.

[0012] In addition, the first and second spiral conveyor belts are exactly the same in shape and size, which ensures the synchronicity and uniformity of the two conveyor belts during operation.

[0013] To improve conveying efficiency and safety, both the first and second spiral conveyor belts are equipped with anti-slip layers on their transmission surfaces, which can effectively prevent materials from slipping during the conveying process.

[0014] Finally, the motor and the shaft are connected by a coupling. The function of the coupling is to transmit torque and allow a certain degree of misalignment between the two shafts, thereby ensuring the stable operation of the entire blast freezer.

[0015] Compared with the prior art, the beneficial effects of this utility model are: improved production efficiency. Through the design of the double helix conveyor belt, two different materials or two parts of the same material can be processed at the same time, thereby improving the working efficiency of the quick-freezing machine.

[0016] Optimized material handling: staggered spiral conveyor belts can reduce mutual interference between materials during the conveying process, ensuring that materials are conveyed and frozen evenly and stably.

[0017] Enhanced flexibility: The design with two inlets and two outlets allows this freezer to process two different products simultaneously, or to offer a more flexible processing method.

[0018] Stability and reliability are improved by connecting the motor to the shaft via a coupling, which reduces transmission, impact, and vibration, thus enhancing the stability and reliability of the equipment.

[0019] Automation enables the automatic control of the entire quick-freezing process, reducing manual operation and improving production consistency and reliability.

[0020] Structural stability: The elastic support feet at the bottom of the frame improve the stability of the equipment and reduce the impact of vibrations caused by equipment operation on the quick-freezing effect.

[0021] The freezing effect is improved. The freezing equipment is connected to the machine body, ensuring freezing efficiency and freezing quality. At the same time, the freezing equipment can uniformly and quickly freeze materials.

[0022] Safety and maintainability: The motor and shaft are connected by a coupling, which can effectively absorb vibration, reduce mechanical stress, extend the service life of the equipment, and facilitate maintenance and replacement.

[0023] The anti-slip treatment on the conveyor belt surface prevents materials from sliding during transport, making equipment maintenance and cleaning easier and helping to improve production efficiency and extend equipment lifespan. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2 The present invention provides a technical solution: a double spiral quick-freezing machine with an auxiliary feeding structure, the quick-freezing machine includes a frame 1 and a body 2, wherein the body 2 is mounted on the frame 1;

[0029] Inside the machine body 2, a rotating shaft 3 is installed, on which a first spiral conveyor belt 4 and a second spiral conveyor belt 5 are mounted, and these two spiral conveyor belts 4 and 5 are arranged alternately. The rotating shaft 3 is driven by a motor 11 to realize the rotational movement of the conveyor belts;

[0030] The machine body 2 has two feed inlets 6 on its upper part, and these two feed inlets correspond to the feed ends of the first spiral conveyor belt 4 and the second spiral conveyor belt 5, respectively. Simultaneously, the machine body 2 also has two discharge outlets 7 on its upper part, and these two discharge outlets also correspond to the discharge ends of the first spiral conveyor belt 4 and the second spiral conveyor belt 5, respectively.

[0031] Feed conveyor belts 8 are installed at the feed ends of both the first spiral conveyor belt 4 and the second spiral conveyor belt 5 to facilitate the smooth entry of materials. Similarly, discharge conveyor belts 9 are installed at the discharge ends of both the first spiral conveyor belt 4 and the second spiral conveyor belt 5 to ensure the smooth output of materials.

[0032] The machine body 2 is also equipped with a refrigeration device 10, which is connected to the machine body 2, so as to effectively freeze the materials on the conveyor belt.

[0033] More specifically, the bottom of the frame 1 is designed with elastic support legs 12, which can provide a certain cushioning effect to reduce the impact of vibrations generated by the machine during operation on the ground.

[0034] Furthermore, the machine body 2 is also equipped with a controller 13, which is electrically connected to the feeding conveyor belt 8, the discharging conveyor belt 9, the freezing equipment 10 and the motor 11, so that the working status of the entire quick-freezing machine can be centrally controlled and managed.

[0035] In addition, the first spiral conveyor belt 4 and the second spiral conveyor belt 5 are exactly the same in shape and size, which can ensure the synchronicity and uniformity of the two conveyor belts during operation.

[0036] To improve conveying efficiency and safety, anti-slip layers are provided on the transmission surfaces of the first spiral conveyor belt 4 and the second spiral conveyor belt 5, which can effectively prevent materials from slipping during the conveying process.

[0037] Finally, the motor 11 and the rotating shaft 3 are connected by a coupling 14. The function of the coupling 14 is to transmit torque and allow a certain degree of misalignment between the two shafts, thereby ensuring the stable operation of the entire quick-freezing machine.

[0038] Working principle: When the double spiral quick-freezing machine is needed during operation, the motor 11 is started first, and the motor transmits power to the rotating shaft 3 through the coupling 14.

[0039] Material enters the first spiral conveyor belt 4 and the second spiral conveyor belt 5 through inlet 6. There are two inlets, corresponding to the inlet ends of the two spiral conveyor belts respectively. Feed conveyor belt 8 is located at the inlet end of each spiral conveyor belt and is used to assist in the uniform distribution and conveying of material.

[0040] The rotation of shaft 3 drives the first spiral conveyor belt 4 and the second spiral conveyor belt 5 to rotate synchronously. The two spiral conveyor belts are staggered, allowing for the simultaneous processing of different batches of materials and improving work efficiency. The spiral conveyor belts are identical in shape and size, ensuring consistent conveying. An anti-slip layer is provided on the conveying surface of the conveyor belts to prevent materials from slipping during transport.

[0041] During the conveying process, the refrigeration equipment 10 starts working, using the refrigeration system of the machine body 2 to quickly freeze the materials. The refrigeration equipment is connected to the machine body to ensure uniform and efficient freezing.

[0042] Driven by the screw conveyor belt, the material undergoes quick-freezing treatment and then reaches the discharge end. The discharge conveyor belt 9 is located at the discharge end of each screw conveyor belt and is used to smoothly transport the quick-frozen material to the discharge port 7. There are two discharge ports, corresponding to the discharge ends of the two screw conveyor belts respectively.

[0043] The entire operation of the quick-freezing machine is controlled by controller 13. The controller is electrically connected to the feeding conveyor belt, the discharging conveyor belt, the freezing equipment, and the motor, and can realize the automated control of the entire quick-freezing process, including speed regulation, temperature control, and material flow control.

[0044] The bottom of the frame 1 is equipped with elastic support feet 12 to ensure the stability of the machine during operation and reduce the impact of vibration on the quick-freezing effect.

[0045] In summary, this twin-spiral quick-freezing machine with an auxiliary feeding structure uses a motor to drive the rotating shaft, utilizes a spiral conveyor belt to transport and quick-freeze materials, cools them through a freezing device, and finally outputs the quick-frozen materials through a discharge conveyor belt. The entire process is automatically controlled by a controller.
