Description

Technical Field

[0001] This utility model relates to the field of coffee liquid concentration devices, and in particular to a coffee liquid membrane concentration device. Background Technology

[0002] Coffee is usually served in two forms: roasted and ground coffee and instant coffee. Traditional coffee brewing involves roasting coffee beans, grinding them on-site, and then brewing them using a percolator. During the brewing process, the coffee is filtered through filter paper (filter cloth) and other filter materials to remove residue, resulting in freshly ground coffee with excellent taste and flavor. However, this method takes a relatively long time.

[0003] For example, a patent entitled "A Coffee Concentration Device" (patent application number: CN202020837321.8) discloses a coffee concentration device. This device utilizes the fact that the freezing point of water in a coffee solution is higher than that of the soluble coffee substance solution. When the temperature of the freezing tank drops to the freezing point, the water in the solution freezes first and floats to the top of the liquid surface. This process circulates at a constant temperature, causing the water in the solution to continuously precipitate out and freeze, floating to the top layer. At this point, the lower layer of solution is removed, thus obtaining concentrated coffee concentrate with a large amount of water removed. However, before the water in the coffee solution freezes, a coffee film easily forms on the surface. If the film freezes or solidifies, it can easily affect the precipitation of water. Additionally, the coffee solution, discharged from a height, can easily splash and adhere to the inner wall of the freezing tank, causing inconvenience for later cleaning.

[0004] Therefore, it is necessary to propose a coffee liquid film concentration device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a coffee liquid film concentration device to solve the problem that before the water in the coffee liquid freezes, a coffee liquid film easily forms on the surface of the coffee liquid. If the film freezes or solidifies, it will easily affect the water extraction. At the same time, the coffee liquid is discharged from a height and is easy to splash and adhere to the inner wall of the freezing tank, which will easily cause inconvenience in later cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coffee liquid film concentration device, comprising a freezing chamber and an ambient temperature chamber disposed at the bottom of the freezing chamber, wherein a freezing tank is fixed in the freezing chamber, the bottom end of the freezing tank extends into the ambient temperature chamber, and a steam input pipe and a raw liquid input pipe are connected to the top of the freezing tank, and a cooler is fixed on the inner wall of the freezing chamber;

[0007] The bottom end of the raw liquid input pipe is connected to a connecting pipe, which extends into the bottom of the freezer. A lifting sliding plate is slidably fitted on the outside of the connecting pipe. The outside of the lifting sliding plate is in contact with the inner wall of the freezer. Multiple through holes are provided on the lifting sliding plate. Multiple spikes are provided at the bottom end of the lifting sliding plate. A receiving block is fixed at the bottom end of the outside of the connecting pipe. The receiving block is located below the lifting sliding plate.

[0008] Preferably, the bottom of the freezer is connected to a drain pipe, a base is provided below the drain pipe, and a container is placed on the top of the base, with the container corresponding to the bottom of the drain pipe.

[0009] Preferably, a hot air blower is fixed to one side of the ambient temperature chamber, and the air outlet of the hot air blower is connected to an air supply pipe, with one end of the air supply pipe extending into the outside of the ambient temperature chamber directly opposite the freezer tank.

[0010] Preferably, multiple temperature sensors are embedded in the inner wall of the freezing tank, and the multiple temperature sensors are distributed at equal intervals along the height direction of the freezing tank.

[0011] Preferably, the bottom end of the lifting sliding plate is provided with multiple grooves, which are evenly distributed at the bottom end of the lifting sliding plate. A spring is fixed in each of the multiple grooves. The top end of the spike is fixedly connected to the bottom end of the spring, and the spike slides into the corresponding groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In the actual operation of this utility model, the coffee concentrate is introduced into the bottom of the freezer through the connecting pipe. Due to the restriction of the connecting pipe, the coffee concentrate is prevented from falling from a height and splashing onto the inner wall of the freezer, making the coffee concentrate input more stable. At the same time, as the coffee concentrate is introduced, the height of the coffee concentrate in the freezer rises, which will push the lifting sliding plate to slide upward. The sliding plate will always press against the top of the coffee concentrate.

[0014] 2. When a coffee film forms on the surface of the coffee liquid, the spikes at the bottom of the lifting sliding plate will pierce the coffee film, preventing it from forming an ice film after freezing, which would affect water extraction. At the same time, it allows the coffee film and coffee liquid to mix again, facilitating the formation of concentrated coffee liquid. Meanwhile, as the coffee liquid level changes, the lifting sliding plate will also rise and fall accordingly, thereby rubbing against the inner wall of the freezing tank to remove adhering coffee liquid or fixed coffee particles. Furthermore, when water in the coffee solution precipitates and forms ice cubes, the automatic gravity of the lifting sliding plate will compress the ice cubes, reducing the gaps between the ice cubes and preventing coffee liquid from remaining in the gaps between the ice cubes.

[0019] This utility model provides, for example Figures 1-3 The coffee liquid film concentration device shown includes a freezing chamber 1 and an ambient temperature chamber 2 located at the bottom of the freezing chamber 1. A freezing tank 3 is fixed inside the freezing chamber 1, with the bottom of the freezing tank 3 extending into the ambient temperature chamber 2. A steam input pipe 4 and a raw liquid input pipe 5 are connected to the top of the freezing tank 3. A refrigerator 7 is fixed on the inner wall of the freezing chamber 1. A drain pipe 16 is connected to the bottom of the freezing tank 3. A base 9 is located below the drain pipe 16, and a container 8 is placed on the top of the base 9. The container 8 corresponds to the bottom of the drain pipe 16.

[0020] After the coffee liquid to be concentrated is injected into the freezing tank 3 through the raw liquid inlet pipe 5, the temperature inside the freezing chamber 1 is lowered by starting the refrigeration unit 7, so that the coffee raw liquid inside the freezing tank 3 is frozen together.

[0021] Because the freezing point of water in the coffee solution is higher than that of the coffee solution, the water in the solution freezes first and floats on the surface when the temperature of the freezing tank drops to the freezing point. This process circulates at a certain constant temperature, causing the water in the solution to continuously precipitate out of the original solution, thereby concentrating the coffee liquid. The concentrated coffee liquid can be discharged by opening the drain pipe 16.

[0022] The bottom end of the raw liquid input pipe 5 is connected to a connecting pipe 6, which extends into the bottom of the freezer tank 3. A lifting sliding plate 14 is slidably fitted on the outside of the connecting pipe 6. The outside of the lifting sliding plate 14 is in contact with the inner wall of the freezer tank 3. Multiple through holes 15 are provided on the lifting sliding plate 14. Multiple spikes 17 are provided at the bottom end of the lifting sliding plate 14. A receiving block 13 is fixed at the bottom end of the outside of the connecting pipe 6. The receiving block 13 is located below the lifting sliding plate 14.

[0023] The bottom end of the lifting sliding plate 14 has multiple grooves, which are evenly distributed at the bottom end of the lifting sliding plate 14. Springs are fixed in the multiple grooves. The top end of the spike 17 is fixedly connected to the bottom end of the spring, and the spike 17 slides in the corresponding groove.

[0024] In the actual operation of this utility model, the coffee concentrate is input into the bottom of the freezer tank 3 through the connecting pipe 6. Due to the restriction of the connecting pipe 6, the coffee concentrate is prevented from falling from a height and splashing onto the inner wall of the freezer tank 3, making the input of coffee concentrate more stable. At the same time, as the coffee concentrate is input, the height of the coffee concentrate in the freezer tank 3 rises, which pushes the lifting sliding plate 14 to slide upward. The sliding plate 14 will always press against the top of the coffee concentrate.

[0025] When a coffee film forms on the surface of the coffee liquid, the spikes 17 at the bottom of the lifting sliding plate 14 will pierce the coffee film, preventing the coffee film from forming an ice film after freezing, which would affect the water separation. At the same time, the coffee film and coffee liquid will mix again, making it easier to form a concentrated coffee liquid. Meanwhile, as the coffee liquid level changes, the lifting sliding plate 14 will also rise and fall accordingly, thereby rubbing against the inner wall of the freezing tank 3 to remove the adhering coffee liquid or fixed coffee particles. When the water in the coffee solution separates and forms ice cubes, the lifting sliding plate 14 will automatically squeeze the ice cubes by gravity, reducing the gaps between the ice cubes and preventing coffee liquid from remaining in the gaps between the ice cubes.

[0026] A hot air blower 10 is fixed on one side of the ambient temperature chamber 2. The air outlet of the hot air blower 10 is connected to an air supply pipe 11. One end of the air supply pipe 11 extends into the outside of the ambient temperature chamber 2 directly opposite the freezer tank 3. The hot air blower 10 can heat the bottom of the freezer tank 3 to prevent the concentrated coffee liquid from freezing.

[0027] Multiple temperature sensors 12 are embedded in the inner wall of the freezing tank 3. The multiple temperature sensors 12 are evenly distributed along the height direction of the freezing tank 3, which facilitates the monitoring of liquid temperature at different heights.
