Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee extract storage technology, specifically to a coffee extract buffer container. Background Technology
[0002] To address the issue of long-term preservation of coffee extract, Chinese patent document CN222611722U discloses a coffee extract buffer container that uses a refrigerator to store the coffee extract. However, the refrigerator cools the coffee extract from all sides of the storage container, resulting in a slow cooling rate. Furthermore, after prolonged storage, the coffee extract may separate into layers due to the different densities of its components, affecting its taste and even rendering it undrinkable. To solve these problems, this invention provides a coffee extract buffer container. Utility Model Content
[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a coffee extract buffer container with a rotatable cooling section featuring a bent structure. This not only allows for full contact with the coffee extract, improving heat exchange efficiency and enabling faster cooling of the coffee extract, but also facilitates stirring of the coffee extract to prevent stratification.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a coffee extract buffer container, comprising: The cylinder has an inlet pipe on its upper end face and a sealing cap on the inlet pipe. When adding coffee extract into the cylinder, the sealing cap can be opened and the coffee extract can be directly added into the cylinder through the inlet pipe. The lower end of the cylinder has a discharge pipe with a valve. When it is necessary to remove the coffee extract from the cylinder, the valve on the discharge pipe can be opened. A cooling section is installed on the inner side of the upper end of the cylinder, and the lower end of the cooling section extends to the lower end of the cylinder.
[0005] Preferably, the cooling section has a bent shape.
[0006] Preferably, the cooling section is rotatably mounted inside the cylinder and driven by a motor mounted on the upper end face of the cylinder.
[0007] Preferably, the cooling section has a hollow structure for the circulation of cooling medium.
[0008] Preferably, the upper and lower ends of the cooling section pass through the upper and lower end faces of the cylinder and extend to the outside of the cylinder, and the lower end sidewall of the cooling section is rotatably sealed to the lower end face of the cylinder.
[0009] Preferably, the outer upper end of the cooling section is fixedly connected to a driven gear rotatably mounted on the upper end face of the cylinder, the driven gear meshes with a driving gear rotatably mounted on the upper end face of the cylinder, the driving gear is fixedly connected to the motor shaft of the motor, and the motor is mounted on the upper end face of the cylinder via a mounting bracket.
[0010] Preferably, the position where the discharge pipe communicates with the cylinder is located on one side of the cylinder's axis, the lower end of the cylinder is an inclined surface, and the position where the cylinder communicates with the discharge pipe is the lowest point of the lower side of the cylinder.
[0011] Preferably, a plurality of integrally formed heat exchange rods are fixedly connected to the cooling section.
[0012] Preferably, the inner sidewall of the cylinder is provided with a heat insulation layer.
[0013] Preferably, the side wall of the cylinder is provided with an observation port, and the inside of the observation port is inlaid with a transparent insulation board.
[0014] The beneficial effects of this utility model are as follows: This invention features a cooling section with a bent and hollow structure, which increases the contact area between the cooling section and the coffee extract when the cooling medium flows through it. Furthermore, multiple heat exchange rods are fixedly mounted on the cooling section, enabling more efficient heat exchange and improving the cooling effect on the coffee extract.
[0015] This invention, through the arrangement of a motor, a driving gear, and a driven gear, enables the cooling section to rotate inside the cylinder, thereby further increasing the dynamic contact range between the cooling section and the coffee extract. Moreover, the rotation of the cooling section can disturb the flow of the coffee extract, preventing the coffee extract from separating during storage.
[0016] This invention reduces heat loss from the low-temperature coffee liquid inside the cylinder by setting an insulation layer inside the side wall of the cylinder, thereby better maintaining the coffee liquid at a low temperature, reducing the energy consumption of the refrigeration system, and thus achieving energy-saving effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0026] This invention provides a coffee extract buffer container, such as... Figures 1 to 6 As shown.
[0027] Example 1: This invention provides a coffee extract buffer container, including a cylindrical body 1. The top of the cylindrical body 1 is provided with an inlet pipe 2 and a sealing cap, and the bottom is provided with a discharge pipe 3 with a valve. Coffee extract can be added into the cylindrical body 1 through the inlet pipe 2, and the coffee extract inside the cylindrical body 1 can be removed by opening the valve and discharging through the discharge pipe 3. A cooling section 4 is installed inside the cylindrical body 1. The cooling section 4 has a bent structure and is hollow. The upper and lower ends of the cooling section 4 penetrate the upper and lower end faces of the cylindrical body 1, respectively. Cooling medium (which can be a coolant) can flow from the upper end to the lower end of the cooling section 4 to cool the coffee extract inside the cylindrical body 1. The bent structure of the cooling section 4 increases the contact area between the cooling section 4 and the coffee extract, thereby increasing the heat exchange area, improving the heat exchange efficiency, and promoting faster cooling of the coffee extract.
[0028] Furthermore, multiple heat exchange rods 9 are symmetrically distributed on the cooling section 4. The multiple heat exchange rods 9 on the same side are distributed along the trajectory of the cooling section 4. The heat exchange rods 9 are integrally formed with the cooling section 4, and the material is a material with high thermal conductivity (such as copper), which can further improve the efficiency of heat exchange.
[0029] The cylinder 1 is fixedly connected to a support leg, which allows the outlet of the discharge pipe 3 to be suspended in the air. One end of the outlet of the discharge pipe 3 is folded downward, which makes it easier for staff to collect the coffee extract inside the cylinder 1 when it is discharged.
[0030] Example 2: Based on Embodiment 1, to prevent coffee from separating due to prolonged standing, the cooling section 4 is rotatably installed inside the cylinder 1 and driven by a motor 5 mounted on the cylinder 1. The upper end of the cooling section 4, located on the outer side of the cylinder 1, is fixedly connected to a driven gear 6 rotatably mounted on the cylinder 1. The driven gear 6 meshes with a driving gear 7 rotatably mounted on the cylinder 1. The driving gear 7 is fixedly connected to the motor shaft of the motor 5. The motor 5 is mounted on the upper end face of the cylinder 1 via a mounting bracket 8. The rotation of the motor shaft of the motor 5 can drive the cooling section 4 to rotate, which not only increases the dynamic contact range between the cooling section 4 and the coffee extract, but also disturbs the flow of the coffee extract, preventing the coffee extract from separating due to prolonged standing.
[0031] The lower end of the cooling section 4 is rotated and sealed with the lower side wall of the cylinder 1, so that the coffee extract inside the cylinder 1 will not leak due to the rotation of the cooling section 4. This sealing method can achieve a labyrinth seal through a sealing ring (this sealing method is now widely used, so it will not be described in detail in this utility model).
[0032] In order to ensure that the cooling section 4 does not affect the flow of the cooling medium during rotation, the upper and lower ends of the cooling section 4 are aligned with the axis of the cylinder 1. At this time, the position where the discharge pipe 3 communicates with the lower side of the cylinder 1 is located on one side of the axis of the cylinder 1. The lower end face of the cylinder 1 is set as an inclined surface, and the lowest point of this inclined surface is located at the position where the discharge pipe 3 communicates with the cylinder 1, so that the coffee extract inside the cylinder 1 can be discharged better.
[0033] Example 3: Based on Example 2, in order to better maintain the low temperature of the coffee extract, an insulation layer 10 is provided inside the side wall of the cylinder 1 to prevent heat loss and better maintain the low temperature inside the cylinder 1.
[0034] To observe the remaining amount of coffee extract inside the cylinder 1, a long, narrow observation port is provided on the side wall of the cylinder 1. A transparent insulation plate 11 is embedded inside the observation port. This prevents heat loss and allows staff to easily observe the remaining amount of coffee inside the cylinder 1. The insulation plate 11 can be made of double-layered vacuum glass and can also be marked with graduations. The graduations gradually decrease from top to bottom, allowing staff to accurately report the remaining amount of coffee extract inside the cylinder 1.
[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
