Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, especially ice-making equipment for making edible snowflakes, ice cubes, etc. Background Art

[0002] With the development of society and the diversification of people's lives, various delicacies such as snacks, cold drinks, and pastries are deeply loved by people, especially favored by young people. For this reason, equipment for processing such delicacies has emerged one after another. For example, a snow ice machine, which is a type of ice-making machine, can quickly freeze the liquid material into ice and use a knife and shovel to cut it to form delicate snow ice, enabling the snow ice to be made and eaten immediately. The existing snow ice machines mainly consist of two major units: a refrigeration unit and a snow-making unit. The core component of the snow-making unit is the evaporator drum. The evaporator drum is driven by a motor to rotate. The refrigeration unit inputs high-temperature and high-pressure refrigerant into the evaporator drum through the refrigerant inlet pipeline, and then transports it back to the refrigeration compressor through the refrigerant return pipeline. Due to the rapid change in the thermodynamic conditions inside the evaporator drum, the temperature on the outer surface of the evaporator drum will quickly drop below -30°C, causing the liquid material to freeze quickly and adhere to the surface of the evaporator drum. At this time, the ice layer is scraped off the surface of the evaporator drum by corresponding tools, and snowflake-shaped granular ice sand can be scraped out.

[0003] However, in the existing snow ice machines, the internal structure of the evaporator drum, such as the snow machine drum with the Chinese patent publication number CN206459398U, is relatively complex, and at the same time, a large number of parts are used, resulting in too high production costs and too complex installation processes, making the equipment not conducive to promotion. At the same time, the existing snow ice machines have relatively single functions and are difficult to meet actual needs. Especially for mobile food stalls or trunk economy, etc., not only does the equipment need to be small in size, easy to move, carry, and maintain, but it also requires the ability to meet various food processing requirements. Therefore, there is still room for improvement in the existing technology. Summary of the Invention

[0033] The concept, specific structure and technical effects of the utility model will be further described below in conjunction with the drawings to fully understand the purpose, features and effects of the utility model.

[0034] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] Refer to Figures 1 to 12As shown, it is a schematic diagram of a preferred embodiment of the utility model. The utility model is related to a hot and cold all-in-one machine for processing food, which at least comprises: a machine base 1, a snow-making component 2, an ice-making component 3, a refrigeration unit 4 and a corresponding electronic control part; the machine base 1 can be further designed with moving wheels for easy movement and positioning; the refrigeration unit 4 is mainly a refrigeration system composed of a compressor, a condenser, a gas-liquid separator, etc. The refrigeration unit 4 is a prior art, and its working principle will not be repeated here.

[0036] Figures 6 to 9 As shown, the snow-making assembly 2 is mounted on the machine base 1 and is used to make snowflakes. The snow-making assembly 2 has an evaporator roller 21 mounted on the machine base 1 and capable of relatively rotating. The evaporator roller 21 includes a cylindrical barrel 211, a rotating shaft 212 and a liquid return pipe 213 coaxially arranged with the cylindrical barrel. The cylindrical barrel 211 is a hollow structure formed by a first shaft plate 2111, a second shaft plate 2112 and an arc plate 2113 and having a closed inner cavity 2114. In this embodiment, the first shaft plate 2111 and the second shaft plate 2112 are both disc-shaped. Preferably, the outer diameters of the first shaft plate 2111 and the second shaft plate 2112 are the same. After the first shaft plate 2111 and the second shaft plate 2112 are coaxially arranged at intervals, the arc plate 2113 surrounds and encloses the area between the first shaft plate 2111 and the second shaft plate 2112 to form a closed inner cavity 2114 for subsequent introduction of refrigerant. The first shaft plate 2111 is fixedly connected to the rotating shaft 212, and the rotating shaft 212 and the output end of the driving motor 22 are hard-connected for transmission, which reduces the transmission components and transmission distance, optimizes the assembly space, and reduces the overall size of the machine. This transmission structure also effectively reduces transmission vibration, ensuring that the output of the driving motor 22 drives the cylindrical barrel 1 to rotate, so as to make snowflakes later. The return liquid pipe 213 extends outward from the second shaft plate 2112, and the return liquid pipe 213 is connected to the closed inner cavity 2114 of the cylindrical barrel 211, so as to be connected to the refrigeration unit later; the return liquid pipe 213 is connected to the fixed seat 215 through the bearing 214, and the fixed seat 215 is fixed on the machine base 1 to obtain rotation support, ensuring that the cylindrical barrel 1 rotates smoothly.

[0037] Figures 1 to 5, as shown in FIGS. 10, 11, the ice-making assembly 3 is installed on the machine base 1 and provides an ice tray 31. A semi-liquid evaporator 32 that forms a heat conduction system with the ice tray is provided at the bottom of the ice tray 31. The semi-liquid evaporator 32 includes a liquid distribution pipe 321 and evaporation heat exchange pipes 322 that are led out from the liquid distribution pipe 321 and arranged in parallel at intervals. The evaporation heat exchange pipes 322 are attached to the bottom of the ice tray 31 and form a heat conduction system with the ice tray; a first liquid inlet 323 and a first gas return port 324 are further provided on the liquid distribution pipe 321, and the first liquid inlet 323 and the first gas return port 324 are used to connect to the refrigeration unit 4. Further, the evaporation heat exchange pipe 322 is a straight pipe body with one end blocked, and the other end of the evaporation heat exchange pipe 322 is connected to the lower side of the axial interface of the liquid distribution pipe 321; the first liquid inlet 323 is also provided on the lower side of the axial interface of the liquid distribution pipe 321, and the height of the first liquid inlet 323 on the horizontal plane is higher than the part where the evaporation heat exchange pipe 322 is connected to the liquid distribution pipe 321; the first gas return port 324 is provided on the upper side of the axial interface of the liquid distribution pipe 321. Compared with the traditional S-shaped arrangement of heat exchange pipes, the distance between the evaporation heat exchange pipes 322 of the present invention can be smaller, obtaining a denser arrangement, solving the technical problem that the traditional S-shaped arrangement is affected by the turning radius and cannot arrange the heat exchange pipes closer. Therefore, the structure of the present invention is more compact, with a small volume, and is more conducive to the ice-making work of the ice tray 31, improving the ice-making speed, efficiency, and quality. By feeding liquid and exhausting gas through the liquid distribution pipe 321, not only the structure manufacturing is optimized, but also the synchronous operation of multiple evaporation heat exchange pipes 322 can be achieved, with consistent performance, reduced loss, energy saving, environmental protection, and improved ice-making speed, efficiency, and quality.

[0038] The refrigeration unit 4 is installed on the machine base 1 and supplies refrigerant to the snow-making assembly 2 and the ice-making assembly 3 in a parallel manner. Specifically, it can be controlled for use through corresponding pipeline switches during implementation. The refrigerant is led into the closed inner cavity 2114 of the evaporator drum 21 of the snow-making assembly 2. The rapid change of the thermodynamic conditions inside the evaporator drum will cause the temperature of the outer surface of the evaporator drum to rapidly drop below -30°C, enabling the corresponding liquid material to quickly freeze and adhere to the surface of the evaporator drum 21 of the snow-making assembly 2. Subsequently, the ice layer can be scraped off to make snowflakes. The refrigerant is led into the semi-liquid evaporator 32 of the ice-making assembly 3, allowing the corresponding liquid material to freeze into ice cubes in the ice tray 31 of the ice-making assembly 3.

[0039] Figure 1 , 2As shown in Figures 4, 5, and 11, the machine base 1 is also provided with a collapsible extension bracket 11 and a storage space 12 adapted for storing the extension bracket 11. A grilling component 5 is provided on the extension bracket 11. The storage space 12 is a flat-layer space with a lateral opening, and is further arranged below the ice-making component 3, making full use of the geometric space of the machine base 1 to achieve an effective integrated design. The extension bracket 11 is a drawer-type push-pull bracket and is correspondingly installed in the storage space 12 through linear slide rails, enabling the extension bracket 11 to be pulled out or retracted along the storage space 12. The grilling component 5 includes a baking tray 51 positioned on the extension bracket 11 and an electric heater 52 attached to the bottom of the baking tray. When in use, the extension bracket 11 is pulled out, and the grilling component 5 follows and is moved out. At this time, cooking operations such as frying, grilling, and stir-frying can be carried out using the grilling component 5 to meet the needs of the public.

[0040] Figures 6 to 9 As shown, the snow-making component 2 further includes a material tank 23, a scraper 24 installed on the side of the material tank, and a feeding bucket 25. The material tank 23 is installed on the machine base 1 and can be further designed to be detachable for convenient disassembly, assembly, and maintenance. In this embodiment, the feeding bucket 25 is vertically positioned on the machine base 1 and automatically feeds the material tank 23. The evaporator drum 21 is installed on the machine base 1 of the snow ice machine and is connected to the refrigeration unit to establish a refrigerant circulation system, enabling the high-temperature and high-pressure refrigerant input into the evaporator drum by the refrigeration unit through the refrigerant inlet pipe, and then being transported back to the refrigeration compressor through the refrigerant return pipe; and the evaporator drum is partially immersed in the material tank 23. By rotating the evaporator drum 21 to contact the liquid material, the liquid material is quickly frozen and adheres to the surface of the evaporator drum. Then, the ice layer is scraped off from the surface of the evaporator drum by the scraper 23, and snowflake-shaped granular ice sand can be scraped out for consumption.

[0041] In this embodiment, the evaporator drum 21 is fixedly connected to the machine base 1 through a fixing seat 215, and a lubricating oil path is constructed between the liquid return pipe 213 and the fixing seat 215, so that the refrigerant flowing back in the liquid return pipe 213 can lubricate the bearing 214 through the lubricating oil path, achieving the self-adaptive lubrication effect in a sealed environment, ensuring the use and extended service life of the bearing, and thus guaranteeing the normal rotation of the evaporator drum. Further, in this embodiment, the lubricating oil path is in the form of a three-dimensional structure. The lubricating oil path includes a liquid storage tank 216 formed between the end of the liquid return pipe 213 and the fixing seat 215, a liquid replenishing tank 217 formed between the outer periphery of the liquid return pipe 213 and the fixing seat 215, and a liquid guiding hole 218 capable of automatically replenishing the refrigerant in the liquid storage tank 216 to the liquid replenishing tank 217. The liquid replenishing tank 217 leads to the bearing 214. Further, the liquid guiding hole 218 is the fitting gap between the outer periphery of the liquid return pipe 213 and the fixing seat 215. The liquid guiding hole 218 automatically replenishes the refrigerant in the liquid storage tank 216 to the liquid replenishing tank 217 based on the capillary phenomenon. In this embodiment, the liquid storage tank 216 to the liquid replenishing tank 217 is stepped upward, and the lubrication is automatically replenished by using the capillary phenomenon and liquid pressure. This structure utilizes the lubrication characteristics of the refrigerant, and through the transmission relationship between the liquid storage tank, the liquid replenishing tank, and the liquid guiding hole capable of automatically replenishing the refrigerant in the liquid storage tank to the liquid replenishing tank, the lubrication of the bearing is achieved, reducing the process of external oil injection lubrication, and also avoiding the consequences caused by the inability to lubricate the bearing, which helps to improve the performance of the evaporator drum, with a compact structure and convenient maintenance.

[0042] In this embodiment, the fixed seat 215 is axially spliced and constructed by a first seat body 2151 and a second seat body 2152. The first seat body 2151 is sleeved on the outer periphery of the liquid return pipe 213, and a first sealing ring 2153 is provided at the sleeved position to achieve rotational sealing; the bearing 214 is embedded between the first seat body 2151 and the liquid return pipe 213 to play a role of rotational support. The second seat body 2152 axially abuts against the first seat body 2151 and is connected together by fasteners, and the second seat body 2152 and the liquid return pipe 213 enclose and construct a lubricating oil path, which has a simple structure and is convenient for disassembly, installation and maintenance. In this embodiment, the second seat body 2152 is locked to the first seat body 2151 by screws, and a second sealing ring 2154 is provided at the joint where the second seat body 2152 abuts against the first seat body 2151, so that the second seat body 2152 and the liquid return pipe 213 enclose and construct a lubricating oil path. The second seat body 2152 of this embodiment is in a bowl shape to cover the liquid return pipe 213. A stepped groove is reserved inside the second seat body 2152 to cooperate with the outer periphery of the liquid return pipe 213 to construct a liquid replenishing groove and a liquid guiding hole. The end of the liquid return pipe 213 extends towards the inner bottom of the second seat body 2152 and has a spacing, so as to cooperate with the groove reserved inside the second seat body 2152 to construct a liquid storage tank 216. In this way, part of the refrigerant flowing back through the liquid return pipe 213 stays in the liquid storage tank for lubricating the bearing 214. In this embodiment, an external connection hole 2155 is provided on the second seat body 2152. The external connection hole 2155 communicates with the liquid return pipe 213 and is used to connect the refrigeration unit 4 of the snow ice machine. Figure 7 , 8 As shown in FIGS. 9, the external connection hole 2155 is opened in the central area of the second seat body 2152. The inner end of the external connection hole 2155 is coaxially aligned with the liquid return pipe 213, and the outer end of the external connection hole 2155 extends in a direction away from the liquid return pipe 213 for subsequent connection to the refrigeration unit. Specifically, the external connection hole 2155 can be connected to the refrigerant pipeline of the refrigeration unit by means of threaded connection or the like. The refrigerant pipeline (not shown in the figure) includes an intake pipe and a return pipe. Preferably, the intake pipe passes through the external connection hole 2155 and the liquid return pipe 213 and extends into the closed inner cavity 2114 of the cylindrical barrel 211 to realize the input of the refrigerant provided by the refrigeration unit into the evaporator drum for making snowflakes; at the same time, the refrigerant in the closed inner cavity 2114 can also return to the compressor of the refrigeration unit through the liquid return pipe 213, the external connection hole 2155 and the return pipe, and so on in a cycle.

[0043] In this embodiment, preferably, the arc plate 2113 is fixedly connected to the first shaft plate 2111 and the second shaft plate 2112 by welding to form an integrated structure, which has a stable structure and good airtightness. Further, the arc plate 2113 is composed of an inner support plate 21131 and an outer layer plate 21132, which is beneficial for manufacturing. The two pairs of side edges of the inner support plate 21131 respectively support the first shaft plate 2111 and the second shaft plate 2112 to maintain the relative spatial relationship between the first shaft plate 2111 and the second shaft plate 2112 and obtain the required spatial dimensions; while the outer layer plate 21132 covers the inner support plate 21131, and the two pairs of side edges of the outer layer plate 21132 respectively overlap on the outer circumferences of the first shaft plate 2111 and the second shaft plate 2112, making the outer circumference of the cylindrical barrel 211 smooth and flat, which is beneficial for icing and ice hanging, and also convenient for scraping off the ice layer. The inner support plate 21131 is provided with liquid permeating holes 21133 so that the refrigerant entering the closed inner cavity 2114 can act on the inner side surface of the outer layer plate 21132 through the liquid permeating holes 21133, so that the rapid change of the thermodynamic condition inside the cylindrical barrel 211 will cause the temperature of the outer surface of the cylindrical barrel to rapidly drop below -30 °C, thereby enabling the liquid material to rapidly freeze and adhere to the surface of the cylindrical barrel. In this embodiment, the liquid permeating holes 21133 are evenly spaced around the closed inner cavity 2114 on the inner support plate 21131 to ensure that the inner side surface of the outer layer plate 21132 is uniformly heated; the liquid permeating holes 21133 are formed by locally tearing and shaping the inner support plate 21131, and a pocket shape is formed at the shaping part, which is beneficial for accommodating the refrigerant and maintaining the action on the inner side surface of the outer layer plate 21132 to ensure ice hanging on the surface of the cylindrical barrel.
