Description

Technical Field

[0001] This utility model relates to the field of intelligent catering equipment technology, specifically to an intelligent freshness-locking self-service milk tea machine. Background Technology

[0002] With the rapid development of the new-style tea beverage market and the increasing demands of consumers for beverage quality, self-service and intelligent freshly made beverage equipment has gradually become a research hotspot in the catering technology field. Traditional beverage vending machines mainly sell canned or bottled drinks, failing to meet users' needs for fresh and customized beverages. In recent years, some self-service milk tea machines have begun to realize functions such as raw material storage, automatic mixing, and cup sealing and dispensing, promoting the automation of beverage production. These devices typically integrate refrigeration systems, pumping devices, heating units, and control systems, enabling the basic production process of a cup of milk tea to be completed unattended. However, existing equipment still has significant shortcomings in terms of raw material preservation, heating methods, temperature control accuracy, and overall automation level, making it difficult to truly reproduce the fresh taste and quality stability of hand-made beverages.

[0003] However, existing self-service milk tea machines on the market generally suffer from a problem of a single temperature zone in their refrigeration system. Different ingredients such as milk and tea share the same refrigeration space, making it impossible to control the temperature in separate zones according to their respective optimal preservation temperatures. This leads to some ingredients being prone to spoilage or flavor deterioration. At the same time, the heating system often uses a continuous heating tank to keep the tea or milk warm for a long time. This not only causes the tea to become astringent and lose nutrients due to prolonged boiling, but also easily leads to scale buildup, affecting the lifespan of the equipment and hygiene safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent freshness-preserving self-service milk tea machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart freshness-locking self-service milk tea machine, comprising a movable shell; a refrigeration system, disposed inside the movable shell, comprising a base plate disposed at the bottom of the movable shell, a cabinet assembly disposed at the top of the base plate, a storage assembly disposed inside the cabinet assembly, and two sets of extraction components disposed at the top of the base plate and on both sides of the cabinet assembly; and a heating system, disposed inside the movable shell and on one side of the refrigeration system, comprising a shell assembly disposed at the bottom of the movable shell, and two sets of inlet components disposed on both sides of the shell assembly.

[0115] The heat-conducting frame is a rectangular structure, with 421 made of high-strength aluminum alloy. The heating bend 423 is made of food-grade stainless steel. The outlet pipe 424 is also made of food-grade stainless steel. The PTC heating element 422 dissipates heat, which is transferred to the liquid ingredient through the heating bend 423. The heated liquid then flows out through the outlet pipe 424. This provides instant liquid heating to ensure the beverage reaches the user's desired temperature.

[0116] In actual use, the user first selects the desired beverage type, flavor, temperature, etc., via the touchscreen (not shown in the figure) of the ordering system 2. The ordering system 2 sends the user's selection information to the central control system (not shown in the figure), which then calls up the corresponding recipe and operating procedure based on the beverage type selected by the user. The refrigeration system 3 extracts the corresponding raw materials through peristaltic pumps 343 according to the type of beverage selected by the user. The partitioned storage function of the refrigeration system 3 ensures that each raw material is at its optimal preservation temperature, such as 2 to 6 degrees Celsius for milk and 2 to 4 degrees Celsius for tea. The air conditioning system 8 is equipped with a temperature sensor (not shown in the figure) to monitor the temperature inside the refrigerated cabinet 321 in real time to ensure the freshness of the raw materials. The refrigeration compressor inside the air conditioning system 8 automatically adjusts the refrigeration power according to the feedback from the temperature sensor to maintain a stable temperature inside the refrigerated cabinet. The user sends the extraction information to the central control system through the touch screen. The central control system issues extraction commands to the two sets of peristaltic pumps 343. The two sets of peristaltic pumps 343 start, and the two sets of liquid extraction hoses 341 respectively extract the liquid from the two storage containers 331 containing milk and tea into the two sets of first delivery pipes 342, and then flow through the first delivery pipes 342. The milk and tea then enter different heating chambers of the heating housing 411 via the second delivery pipe 344. The two liquids enter the two sets of heating bends 423 respectively through the two sets of second delivery pipes 344. At this point, the user selects a suitable temperature via the touchscreen of the ordering system 2 (the heating system 4 heats the liquid ingredients instantly via the liquid pipe heating device according to the user's selected beverage temperature). The user sends the heating information to the central control system via the touchscreen. The central control system issues heating commands to the two sets of PTC heating elements 422. The PTC heating elements 422 begin to emit heat and heat according to the target temperature set by the user. Simultaneously, the PTC heating elements 422 adhere to the heating bends 423 to transfer heat. A heating sensor (not shown in the figure) inside the heating housing 411 monitors the temperature inside the heating bends 423 in real time to ensure effective heating.The intelligent controller inside the heating shell 411 automatically adjusts the heating power and time according to the user's selected beverage temperature. Then, after the raw liquid is heated by the two sets of heating bends 423, it continues to flow into the two sets of outflow pipes 424, and then enters the two sets of liquid storage tanks inside the filling system 6. Next, the central control system controls the automatic cup dispensing system 5 to lower the cup from the bottom of the cup holder. The high and low forks control the cup's descent through alternating extension and retraction. The central control system also controls the drive motor (not shown in the diagram) to start, transporting the slide and cup to the juice guide. Below the container, the bottling system 6 controls two sets of delivery pumps (not shown in the figure) for two liquid storage tanks, transporting the liquid raw materials to the mixing area through pipelines. Flow sensors (not shown in the figure) inside the bottling system 6 monitor the flow rate of the liquid raw materials in real time to ensure mixing accuracy. The mixed raw materials enter the filling tanks inside the bottling system 6, ready for filling. Two sets of filling tanks, one containing milk and the other tea, add the two raw materials to the cups through pipelines. The central control system controls the proportions of the beverage selected by the user and the preset recipe within the bottling system 6. A control valve (not shown in the figure) and a flow sensor ensure that milk and tea are added to the cup in a set ratio. The powder system 7 contains multiple powder storage tanks for storing raw powder materials. These tanks are connected to a screw conveyor (not shown in the figure) inside the powder system 7 via pipes. The central control system controls the screw conveyor to deliver the powder to be poured into the cup through the pipes. A weighing sensor (not shown in the figure) inside the powder system 7 monitors the weight of the hopper in real time to ensure accurate powder measurement. Then, the central control system controls the robotic arm 11 to grab the cup and place it into the sealing system. Inside the cup-holding plate of the sealing system 12, the cup lid film is passed through the support rod and electric rollers (not shown in the figure) to ensure that the cup lid film is below the heating plate (not shown in the figure). The electric telescopic rod (not shown in the figure) inside the sealing system 12 connects to the lifting plate, which drives the heating plate to press down and pulls the cup lid film to the top of the cup. The electric rollers inside the sealing system 12 start to stretch the sides of the cup lid film to ensure that the cup lid film is flat. The heating plate heats the contact point between the cup lid film and the packaged cup, so that the cup lid film is fused to the top of the packaged cup. The electric telescopic rod drives the lifting plate to rise, and the electric slider drives the sealed packaged cup to move out of the machine through the feeding hole. Then, the central control system controls the robotic arm 11 to grab the sealed cup again and place it at the designated outlet position of the serving system 13. During operation, a monitoring camera (not shown in the figure) is installed inside the movable housing 1 to monitor the operating status of all equipment in real time.

[0117] The refrigerator cabinet 321, peristaltic pump 343, PTC heating element 422, robotic arm 11, touch screen, temperature sensor, heating sensor, drive motor, delivery pump, flow sensor, control valve, spiral powder conveyor, weighing sensor, electric roller, electric telescopic rod, heating plate, and monitoring camera are all electrically connected to the PLC controller.
