Description

TECHNICAL FIELD

[0001] The utility model relates to freezer technical field, concretely is freezer with rotating barrel subassembly. BACKGROUND

[0002] In the field of food freezing processing, such as the freezing process of products like frozen sleep litchi and prepared dishes, it plays a crucial role in the quality of the final product. Immersion freezing technology, as an efficient freezing method, its core lies in immersing the frozen goods into low-temperature freezing liquid. This technology takes advantage of the fact that the heat transfer rate between liquid and solid (or liquid) interface is much higher than that between gas and solid (or liquid) interface, achieving 20-40 times higher heat exchange efficiency. Through direct heat exchange, immersion freezing can achieve rapid freezing of food, while having the advantages of low energy consumption, high freezing quality, etc., showing broad development prospects. Alcohol is considered an ideal freezing liquid for immersion freezing due to its low-temperature antifreeze, corrosion resistance, non-freezing, low cost, good flowability, and easy availability. However, the flammability and evaporation loss risk of alcohol limit its large-scale application in food freezing production and processing. In order to overcome this problem, experts in the field of food science attempt to compound alcohol with other freezing liquids to effectively reduce the volatility of alcohol and improve the safety performance of the freezing liquid. However, the compounded freezing liquid often has defects such as high freezing point or high cost, which affects its widespread application.

[0025] Figure 9 For Figure 8 E-E sectional view. Specific embodiments

[0026] The utility model discloses an embodiment, and specifically makes detailed description as follows.

[0027] As Figures 1 to 9 The refrigerator with rotating barrel assembly shown in the figure, including the casing 1, the casing 1 is equipped with the freezing cavity 11, the casing 1 is equipped with the feeding mechanism 2 that communicates with the freezing cavity 11, the conveying mechanism 3 located the freezing cavity 11, the discharging mechanism 4 that communicates with the freezing cavity 11, the feeding mechanism 2 and / or the discharging mechanism 4 are equipped with rotating barrel assembly 5, the rotating barrel assembly 5 includes the rotating door casing 6 that is connected in the casing 1, the rotating barrel 7 that is connected in the rotating door casing 6, the rotating barrel 7 can rotate relative to the rotating door casing 6, the rotating door casing 6 is equipped with the first opening 61 for the goods to enter or output, the second opening 62 that communicates with the freezing cavity 11, the rotating barrel 7 is equipped with the rotating barrel inner cavity 71 for goods to enter.

[0028] The utility model discloses a rotating barrel that can rotate relative to the rotating door casing, in the feeding or discharging process, the rotating barrel can keep the close cooperation state with the rotating door casing, when the material is in or out of the outside, the freezing cavity keeps the sealed state, to prevent alcohol from evaporating to the outside of the casing, reduce the cold loss caused by the freezing cavity and the outside world keeping connected for a long time, the contact of the material and the rotating barrel is relatively dynamic and not large-area long-time sticking, which reduces the frequent friction of the material and the refrigerator parts, and facilitates the cleaning of the rotating barrel inner cavity for the operator.

[0029] In addition, the existing refrigerator can set up the curtain on the conveying mechanism to reduce the heat loss, but when the curtain contacts the material, bacteria can breed or odor can be produced, generally, the machine needs to be closed to disassemble the curtain for cleaning and reinstallation, which is very inconvenient for the operator, therefore, the refrigerator needs to be improved to reduce the heat loss and facilitate the operator to keep the refrigerator clean and tidy. Compared with the traditional curtain, the curtain needs to be frequently rubbed with the material in the using process, which causes long-time contact and residual stains, bacteria breeding and odor production, etc. The utility model sets up the rotating barrel, which has more stable and reliable sealing performance, avoids the problems of the curtain, such as gap caused by contacting the material or not timely opening and closing, which causes the heat loss caused by the communication between the freezing cavity and the outside world, and the rotating barrel assembly of the utility model is set up, which helps to better maintain the low-temperature environment in the freezing cavity, improves the refrigeration efficiency of the refrigerator, reduces the energy consumption, and ensures that the freezing process can be carried out in a stable and suitable low temperature.

[0030] Furthermore, as a preferred embodiment of this utility model and not a limitation, since the rotating drum assembly achieves material conveying by the rotation of the rotating drum when items enter or leave the freezing chamber, the contact between the material and the rotating drum is relatively dynamic and not a large-area, long-term contact. Operators can always monitor the hygiene of the rotating drum's inner cavity. Without needing to shut down the machine, only routine maintenance work such as periodic cleaning and wiping of the rotating drum's surface or inner cavity is required. This helps maintain the cleanliness and hygiene of the freezer's internal environment, ensuring that frozen foods and other materials are not contaminated. It also reduces the labor intensity of operators, reduces machine downtime caused by cleaning and maintenance work, and ensures the continuity of production and processing.

[0031] Optionally, in some embodiments, the rotating drum assembly may be provided only on the feeding mechanism; alternatively, in other embodiments, the rotating drum assembly may be provided only on the discharging mechanism; of course, in some embodiments, two sets of rotating drum assemblies may be provided and located on the feeding mechanism and the discharging mechanism respectively.

[0032] Specifically, when the rotating drum assembly is installed on the feeding mechanism, the material enters the inner cavity of the rotating drum through the first opening. Under the action of gravity, the material rotates from top to bottom through the second opening and enters the freezing chamber.

[0033] Specifically, when the rotating drum assembly is installed on the discharge mechanism, the material enters the inner cavity of the rotating drum through the second opening from the freezing chamber. Under the action of gravity, the material rotates from top to bottom through the first opening and leaves the discharge mechanism under the action of gravity.

[0034] like Figure 7 The freezer shown has a rotating drum assembly. The rotating drum 7 has connecting shafts 72 on both sides. The rotating door sleeve 6 has a rotating door sleeve cavity 60 for accommodating the rotating drum 7 and openings 63 for the two connecting shafts 72 to extend into and engage. The first opening 61 and the second opening 62 are both connected to the rotating door sleeve cavity 60.

[0035] Furthermore, as a preferred embodiment of this utility model and not a limitation, the connecting shafts on both sides of the rotating drum engage with corresponding openings on the rotating door sleeve. This interlocking connection ensures the rotating drum is securely installed within the rotating door sleeve, preventing wobbling, shifting, or detachment during rotation. This guarantees the stability of the rotating drum assembly under frequent feeding and discharging operations, thereby ensuring the stable operation of the entire refrigeration unit's feeding and discharging process, reducing the risk of malfunctions caused by loose components, and improving the reliability and service life of the equipment. Additionally, the inner cavity of the rotating door sleeve connects the first opening and the second opening, and accommodates the rotating drum, providing a regular and continuous channel for materials to enter and exit the freezing chamber, ensuring smooth material flow. Optionally, in some embodiments, materials enter the inner cavity of the rotating drum through the first opening and smoothly pass through the second opening into the freezing chamber as the rotating drum rotates; or materials enter the inner cavity of the rotating drum through the freezing chamber and the second opening and smoothly exit through the first opening as the rotating drum rotates. This process avoids material accumulation and jamming caused by structural obstructions, improving the material handling efficiency of the refrigeration unit and ensuring the continuity and efficiency of the freezing process.

[0036] Optionally, in some embodiments, when the rotating drum or rotating door sleeve needs maintenance, cleaning, or replacement of parts, the rotating drum can be quickly separated from the inner cavity of the rotating door sleeve by simply pulling out the connecting shaft, thereby shortening equipment downtime and ensuring production continuity.

[0037] like Figure 9 The refrigerator shown has a rotating drum assembly. The rotating drum 7 is provided with a baffle 73 on its outer periphery and a limiting plate 74 extending from the central axis of the rotating drum 7 outward and connected to the baffle 73. The baffle 73 and the limiting plate 74 enclose the rotating drum to form an inner cavity 71.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation, the baffles on the outer periphery of the rotating drum and the limiting plate extending from the central shaft enclose and form the inner cavity of the rotating drum. During the feeding process, the material can be confined within the inner cavity of the rotating drum, preventing accidental spillage during the rotation of the drum. Specifically, the baffles and limiting plates can protect the material. When the rotating drum rotates, in the case of rotation or frequent start-stop, the enclosed inner cavity structure of the rotating drum can limit the range of material movement, reduce violent collisions between materials and between materials and the internal structure of the rotating drum, and ensure that the appearance and quality of the material are not damaged.

[0039] Specifically, when the rotating barrel rotates for feeding or discharging operation, the baffle and the limiting plate can guide the material to move along a predetermined path and manner. The material in the rotating barrel inner cavity is pushed by the baffle and the limiting plate and orderly moves from the first opening to the second opening or is output from the freezing cavity to the first opening through the second opening, which can avoid the material from being blocked or accumulated during the feeding and discharging process, improve the conveying efficiency of the material in the rotating barrel assembly, and further improve the working efficiency of the entire freezer.

[0040] In addition, the connecting structure of the baffle and the limiting plate can increase the overall strength of the rotating barrel. During long-term use, the rotating barrel needs to bear the weight of the material, the centrifugal force during rotation, and external impact. The mutual cooperation of the baffle and the limiting plate forms a reinforcing rib effect, which enables the rotating barrel to better resist external forces, reduces the possibility of deformation or damage, and ensures the long-term stable operation of the rotating barrel.

[0041] Furthermore, the rotating barrel with complete structure and high strength can better cooperate with the rotating door sleeve. The baffle and the limiting plate not only ensure the sealing of the rotating barrel inner cavity but also help maintain the overall shape of the rotating barrel, so that the connection between the rotating barrel and the rotating door sleeve is more compact, further reducing the leakage of cold energy between the rotating barrel inner cavity and the external environment, and ensuring the low-temperature environment of the freezing cavity.

[0042] As shown in the freezer with a rotating barrel assembly, Figure 9 The baffle 73 is arranged in an arc shape, the limiting plate 74 is arranged in a straight shape, the baffle 73 and the limiting plate 74 are provided in plurality, and the plurality of rotating barrel inner cavities 71 are uniformly arranged.

[0043] Further, as a preferred embodiment of the present application, the arc-shaped baffle can better fit and accommodate materials of different shapes. For irregularly shaped materials, the arc-shaped baffle can provide a softer contact surface, reducing the jamming and accumulation of the material in the rotating barrel. At the same time, the straight limiting plate can divide the rotating barrel inner cavity and guide the material, so that more material is uniformly distributed in the plurality of rotating barrel inner cavities. The plurality of uniformly arranged rotating barrel inner cavities greatly increase the amount of material that can be accommodated and processed during one feeding or discharging process, which can fully utilize the internal space without changing the overall size of the rotating barrel, improve the working efficiency of the freezer, and thus improve the simultaneous processing capacity of the freezer for different shaped materials.

[0044] In addition, since the plurality of rotating barrel inner cavities are uniformly arranged, the material can be uniformly conveyed in each inner cavity when the rotating barrel rotates, the center of gravity of the rotating barrel is more stable, and thus the vibration and noise caused by the shift of the center of gravity or the collision of the material are reduced, which can ensure the uniform speed of the material when entering and leaving the freezing cavity, and is conducive to the accurate control of the freezing process and the stability of the product quality.

[0045] As Figure 9 The freezer with the rotating barrel assembly, the outer periphery of the rotating door sleeve 6 is provided with a first door plate 64 and a second door plate 65, the first opening 61 and the second opening 62 are located between the first door plate 64 and the second door plate 65 respectively, the first door plate 64 and the second door plate 65 are both arranged in an arc shape, and the two sides of the first door plate 64 are respectively provided with a first extension 641 extending to the direction of the rotating barrel 7, and the two sides of the second door plate 65 are respectively provided with a second extension 651 extending to the direction of the rotating barrel 7.

[0046] Further, as a preferred embodiment of the utility model but not limited, the first door plate and the second door plate are arranged in an arc shape, and the two sides thereof are respectively provided with a first extension and a second extension extending to the direction of the rotating barrel, which can wrap and shield the opening part of the rotating barrel assembly from multiple directions. When the material enters or exits the freezing cavity, the first door plate, the second door plate, the first extension, the second extension and the rotating barrel can form a more close cooperation, which can reduce the channel of external air entering the freezing cavity on the one hand, greatly enhance the sealing performance of the rotating door sleeve compared with the simple plane door plate structure, thereby more effectively prevent the cold energy in the freezing cavity from being lost, help to maintain the stable low-temperature environment of the freezing cavity, reduce the energy consumption of the freezer and guarantee the freezing effect. On the other hand, it can also prevent the material from being stuck in the gap between the first door plate and the rotating barrel or the gap between the second door plate and the rotating barrel, and ensure the normal rotation of the rotating barrel.

[0047] Specifically, the arc design can effectively utilize the space around the rotating door sleeve to a certain extent, and avoid the safety hazards caused by sharp corners to the surrounding space. The arc-shaped first door plate and the arc-shaped second door plate can provide a smooth transition channel for the material to enter or exit the rotating barrel. When the material enters from the feeding mechanism or is output from the rotating barrel to the discharging mechanism, the arc-shaped surface can guide the material to move along a more suitable path, avoid the material from being stuck, accumulated or even damaged due to sudden angle change, and ensure that the material can flow smoothly and stably in the freezer, thereby improving the efficiency and quality of material conveying.

[0048] As Figure 4 The freezer with the rotating barrel assembly, the rotating barrel assembly 5 includes a first rotating barrel assembly 51 located at the feeding mechanism 2, the first rotating barrel assembly 51 includes a first rotating door sleeve 611 connected to one side of the shell 1, a first rotating barrel 711 connected to the first rotating door sleeve 611, and the feeding height of the feeding mechanism 2 is higher than the height of the second opening 62 of the first rotating door sleeve 611.

[0049] Furthermore, as a preferred embodiment of this utility model and not a limitation, the feeding height of the feeding mechanism is higher than the second opening height of the first rotating door sleeve, so that the material can flow naturally from the feeding mechanism into the first rotating drum assembly by its own gravity. The gravity-based feeding method reduces the need for additional power mechanisms, avoids problems such as jamming and blockage caused by forcibly pushing materials, and allows materials to enter the freezing chamber more smoothly, ensuring the continuity of material transportation and thus improving the working efficiency of the entire freezer.

[0050] In addition, since the material is fed by gravity, the force on the first rotating drum assembly when receiving material is relatively stable, which helps to maintain the stability of the connection between the first rotating drum and the first rotating door sleeve, and reduces the occurrence of problems such as loosening and wear of parts due to uneven force. At the same time, it also helps to maintain good sealing between the two, further preventing cold energy from being lost from this part and ensuring the low temperature environment of the freezing chamber.

[0051] like Figure 5 The freezer shown has a rotating drum assembly. The rotating drum assembly 5 includes a second rotating drum assembly 52 located on the discharge mechanism 4. The second rotating drum assembly 52 includes a second rotating door sleeve 612 connected to the other side of the housing 1 and a second rotating drum 712 connected to the second rotating door sleeve 612. The discharge height of the discharge mechanism 4 is lower than the height of the second opening 62 of the second rotating door sleeve 612.

[0052] Furthermore, as a preferred embodiment of this utility model and not a limitation, the discharge height of the discharge mechanism is lower than the height of the second opening of the second rotating door sleeve. This design allows the material to move naturally from the second rotating drum through the second opening of the second rotating door sleeve to the discharge mechanism by its own gravity. This avoids the need for additional complex pushing devices to drive the material discharge, reduces the possibility of jamming or blockage during the discharge process, and ensures that the material can be continuously and smoothly output from the freezer, improving the efficiency of the entire freezer discharge process. Unlike methods that rely on external mechanical force for forced discharge, gravity-based discharge is gentler. The material moves by its own gravity, effectively avoiding damage caused by strong pulling, collisions, or other mechanical actions.

[0053] In addition, during discharge, the force exerted by the material under gravity on the second rotating drum assembly is relatively stable, which helps to maintain the stability of the connection structure between the second rotating drum and the second rotating door sleeve, reduces problems such as loosening and deformation of components caused by uneven force, and extends the service life of the second rotating drum assembly.

[0054] like Figure 3The freezer with a rotating barrel assembly shown in the figure, the conveying mechanism 3 includes a first conveying end 31 connected with the feeding mechanism 2, a second conveying end 32 connected with the discharging mechanism 4, and a third conveying end 33 located between the first conveying end 31 and the second conveying end 32, the first conveying end 31 is arranged obliquely from top to bottom from the feeding mechanism 2 to the discharging mechanism 4.

[0055] Specifically, the conveying mechanism adopts a belt conveying mode to convey the material.

[0056] Further, as a preferred embodiment of the utility model but not limited, the first conveying end is arranged obliquely from top to bottom from the feeding mechanism to the discharging mechanism, which utilizes the gravity effect to make the material naturally slide downwards to the discharging direction in the initial stage of entering the conveying mechanism, and through the stable conveying process, the material is prevented from being accumulated and blocked at the starting point. The second conveying end is arranged obliquely from bottom to top, which can make the material have a gradual lifting transition at the end of conveying, and through the arrangement of the two different inclined directions of the conveying mechanism, the height of the feeding mechanism and the discharging mechanism is matched to ensure that the material can be continuously, orderly and smoothly moved from the feeding mechanism to the discharging mechanism in the whole conveying process.

[0057] Specifically, when the material just enters the conveying mechanism, the downward inclination of the first conveying end can guide the material to be uniformly distributed on the conveying belt. After the material is conveyed by the front section, the material becomes more regular, and at this time, the second conveying end arranged obliquely upwards can further control the discharging speed and state of the material to ensure that the material enters the discharging mechanism in a suitable state, and finally realizes efficient and stable discharging, and improves the control ability of the whole freezer on the material conveying link. Through the oblique arrangement of the first conveying end downward and the second conveying end upward, a certain space is occupied in the horizontal direction, and at the same time, the vertical space is utilized to make the conveying mechanism realize a longer conveying distance in the limited freezing cavity, improve the space utilization rate, and through the staggered layout mode, the feeding mechanism, the discharging mechanism and the freezing cavity are facilitated to be connected and matched, and the internal structure layout of the whole freezer is optimized, so that it is more compact and orderly.

[0058] As shown in the figure, Figures 3 to 5 The highest position of the first conveying end 31 is lower than the height of the second opening 62 of the first rotating door sleeve 611, and the highest position of the second conveying end 32 is higher than the height of the second opening 62 of the second rotating door sleeve 612.

[0059] Further, as the preferred embodiment of the utility model but not limited, the highest position of the first conveying end is lower than the second opening height of the first rotary door sleeve, so that the material can smoothly transition onto the first conveying end after coming out of the first rotary barrel assembly, avoiding the situation that the material drops due to unreasonable height difference and the like, and ensuring smooth connection of feeding to the conveying link. Similarly, the highest position of the second conveying end is higher than the second opening height of the second rotary door sleeve, so that the material can naturally move towards the second rotary barrel assembly direction after being conveyed by the conveying mechanism, and smoothly enter the discharging link. This height setting ensures that the whole material conveying process of the freezer from feeding, conveying to discharging has continuity, reduces the probability of occurrence of problems such as material jamming and accumulation, and improves the material processing efficiency of the freezer as a whole.

[0060] Specifically, when the material can be smoothly and stably transferred, the connection between the components in the freezer is more close, and there is no situation that the freezing cavity and other parts exchange too much unnecessary air with the outside for a long time due to material blockage, waiting for reorganization and the like. Smooth material transfer helps to maintain a stable low-temperature environment in the freezing cavity, reduces the loss of cold energy to the outside through these connection parts, thereby reducing the energy consumption of the freezer and ensuring the continuity and stability of the freezing effect.

[0061] As shown in the freezer with a rotary barrel assembly, Figures 1 to 3 The lower side of the conveying mechanism 3 is provided with a condensing assembly 8 for cooling, and the upper side of the conveying mechanism 3 is provided with a material pressing assembly 9. The freezing cavity 11 is connected with an air suction device 10 for sucking air.

[0062] Further, as the preferred embodiment of the utility model but not limited, the lower side of the conveying mechanism is provided with a condensing assembly, which can cool the conveying mechanism and its surrounding environment. During the conveying of the material on the conveying mechanism, the material can be in a suitable low-temperature environment from entering the freezer to completing freezing and discharging, thereby improving the quality and efficiency of freezing and ensuring that the frozen products can reach the ideal low-temperature storage state and prolong the shelf life of the products.

[0063] Specifically, the material pressing assembly is located on the upper side of the conveying mechanism, which can press the material downward during the conveying process, helping to evenly spread the material on the conveying mechanism and avoiding the situation that the material is too thick and the internal freezing is uneven. After the material is flattened and compacted, more material can be accommodated in the limited space of the conveying mechanism, improving the space utilization rate. The pressed material is more stable during the conveying process and is not easy to slip or fall due to vibration, shaking and the like, thereby ensuring the smoothness of the material conveying and the reliability of the operation of the whole freezer.

[0064] Specifically, the exhaust system is connected to the freezing chamber and can promptly draw air out of it. On one hand, this removes odors, impurities, and potentially proliferating microorganisms brought in by materials or generated during equipment operation, maintaining fresh and clean air within the freezing chamber. This prevents odors from being absorbed by materials and affecting the product's aroma and quality, ensuring that frozen foods and other materials meet hygiene standards. On the other hand, the exhaust system also regulates the air pressure within the freezing chamber, maintaining it at a suitable and stable level. This is beneficial for the normal progress of the freezing process and the stable operation of the refrigeration system. The air extraction process creates airflow within the freezing chamber, resulting in a more even distribution of cold energy. This prevents localized cold accumulation or uneven temperature distribution, allowing materials to come into full contact with the low-temperature air, maximizing the utilization of cold energy for freezing. This improves the overall refrigeration efficiency of the freezer, reduces energy consumption to some extent, and achieves more efficient freezing processing.

[0065] like Figures 1 to 3 The refrigerator shown has a rotating drum assembly, the condenser assembly 8 includes a condenser tube 81 in contact with alcohol, the pressing assembly 9 is equidistant from the conveying mechanism 3, and the exhaust device 10 is located above the conveying mechanism 3.

[0066] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, alcohol has a low freezing point and a high heat of vaporization. During operation, the condenser tube can rapidly remove heat through heat exchange with the alcohol. Specifically, the temperature of the freezing chamber is below zero degrees Celsius. Compared to the method of directly cooling the air in the freezing chamber and using low-temperature air to cool the material, the alcohol in this utility model remains liquid below zero degrees Celsius, evaporating and filling the entire freezing chamber at low temperatures. The evaporating alcohol can quickly exchange heat with the surface of the material it contacts, accelerating the freezing efficiency.

[0067] Specifically, the exhaust device is located on the upper side of the conveying mechanism, enabling it to more directly remove air from the material surface and surrounding area. During material conveying, the exhaust device located on the upper side can promptly remove air containing alcohol, reducing the risk of flammability and explosion, while also removing the material's own odor and preventing the odor from circulating and being absorbed by the material within the freezing chamber.

[0068] Furthermore, the location of the exhaust system facilitates air circulation within the freezing chamber. It guides the condensed cold air more effectively to the vicinity of the material, resulting in a more uniform distribution of cooling. As the cold air is drawn away, surrounding cold air replenishes it, creating excellent convection and ensuring that all parts of the material are fully exposed to the cold air. This improves freezing efficiency, reduces freezing time, and ensures a more uniform temperature of the frozen material, ultimately enhancing product quality.

[0069] Optionally, in some embodiments, the spacing between the pressure assembly and the conveying mechanism is equal, ensuring that the pressure applied to the material is evenly distributed. During the movement of the material on the conveying mechanism, the material can be subjected to the same degree of downward pressure, avoiding the situation that the material is subjected to excessive or insufficient pressure during the conveying process, so that the material can be distributed on the conveying belt with uniform thickness and density, which is beneficial to the full freezing of the material.
