Description

Technical Field

[0001] This utility model relates to the field of freeze-drying equipment technology, specifically to a high-efficiency freeze-drying equipment for coffee powder. Background Technology

[0002] A high-efficiency freeze-drying device for coffee powder is a device used to convert coffee liquid into coffee powder through low-temperature freezing and vacuum sublimation technology. This device removes moisture by rapidly freezing the coffee liquid at low temperatures and then sublimating the ice directly into water vapor in a vacuum environment, resulting in freeze-dried coffee powder with a water content of less than 5%. This process can effectively preserve the nutrients and flavor of coffee, allowing the freeze-dried coffee powder to dissolve quickly in both hot and cold water, and it has a long shelf life.

[0003] In existing high-efficiency freeze-drying devices for coffee powder, different flavors of liquid coffee are usually poured into their respective trays, which are then placed in the freeze-drying chamber for freeze-drying. However, this method has certain limitations. Since the freeze-drying process removes water through sublimation, i.e., ice directly changes from a solid to a gaseous state, the position of the coffee liquid in the tray affects its freeze-drying speed. Specifically, the coffee liquid at the top of the tray, being closer to the cold source, freezes first, and the resulting ice crystal structure is more conducive to the subsequent sublimation process, thus resulting in a faster freeze-drying speed. In contrast, the coffee liquid at the bottom of the tray freezes unevenly, resulting in lower sublimation efficiency and a slower freeze-drying speed. This uneven freeze-drying effect not only affects the quality and taste of the coffee powder but also reduces production efficiency. Therefore, a high-efficiency freeze-drying device for coffee powder is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency freeze-drying device for coffee powder, in order to solve the problem that when liquid coffee is poured into a tray, the coffee liquid at the bottom of the tray freezes unevenly, resulting in low sublimation efficiency and slow freeze-drying speed. This uneven freeze-drying effect affects the quality and taste of the coffee powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0028] Please see Figure 1-8 This utility model provides a technical solution:

[0029] A high-efficiency freeze-drying device for coffee powder includes a freeze-drying equipment body 1, a controller 2, and a silicone plug 3. A drive assembly 4 is fixedly connected to the inner side of the freeze-drying equipment body 1. A freeze-drying rack assembly 5 is fixedly connected to one end of the drive assembly 4. The drive assembly 4 includes a servo motor 41. An extension fixing column 44 is fixedly connected to the end of the main shaft of the servo motor 41. A fixing plate 42 is fixedly connected to the outer side of the extension fixing column 44. An extension rack 43 is fixedly connected to the rear end of the fixing plate 42. The freeze-drying rack assembly 5 includes a holding cylinder 51. An ear seat 54 is fixedly connected to the outer side of the holding cylinder 51. The ear seat 54 is fixed to a baffle 52 by a fixing bolt 53. A tray frame 55 is fixedly connected to the front end of the holding cylinder 51. The inner side of the holding cylinder 51 is in contact with the outer side of a first silicone ring 56. A connecting column 57 is fixedly connected to the rear end of the first silicone ring 56. A second silicone ring 58 is fixedly connected to the rear end of the connecting column 57. One side of the extension rack 43 is fixedly connected to the outer side of the holding cylinder 51.

[0030] As a further implementation of this solution, a shaft hole is opened at the front end of the freeze-drying equipment body 1, and a silicone sealing ring is fixed inside the shaft hole at the front end of the freeze-drying equipment body 1. An extension fixing post 44 extends to the inside of the shaft hole of the freeze-drying equipment body 1, and the outer side of the extension fixing post 44 fits against the inner side of the silicone sealing ring of the freeze-drying equipment body 1. The housing of the servo motor 41 is fixedly connected to the front end of the freeze-drying equipment body 1. Through the above settings, the use of the silicone sealing ring ensures the sealing between the freeze-drying equipment body 1 and the rotating parts, preventing cold air leakage and the entry of outside air during the freeze-drying process.

[0031] As a further implementation of this solution, the front end of the extended fixed column 44 is fixedly connected to the end of the spindle of the servo motor 41, the rear end of the extended fixed column 44 is fixedly connected to the front end of the tray frame 55, and the servo motor 41 is electrically connected to the controller 2. Through the above settings, this connection method ensures that the extended fixed column 44 can stably drive the tray frame 55 to rotate, so as to achieve uniform freeze-drying of coffee liquid inside multiple containers 51.

[0032] As a further implementation of this solution, an operation port is provided through the rear end of the freeze-drying equipment body 1. The inner side of the operation port of the freeze-drying equipment body 1 is in close contact with the outer side of the silicone plug 3. The controller 2 is fixedly connected to the right side of the freeze-drying equipment body 1. With the above settings, the design of the operation port facilitates observation and operation of the freeze-drying chamber. At the same time, the use of the silicone plug 3 ensures the sealing of the operation port and prevents outside air from entering and affecting the freeze-drying effect.

[0033] As a further implementation of this solution, the inner side of the container 51 is hollow, and both the front and rear ends of the container 51 are through structures. There are multiple containers 51, and equal spacing is provided between them. The outer sides of the first silicone ring 56 and the second silicone ring 58 are both in contact with the inner side of the container 51. The number of first silicone rings 56 is the same as the number of containers 51. A gap is provided between the top of the upper connecting post 57 and the top of the upper first silicone ring 56. Through the above settings, it is easy to install the first silicone ring 56, the connecting post 57 and the second silicone ring 58 into the corresponding container 51. The fit design of the first silicone ring 56 and the second silicone ring 58 with the container 51 ensures that the coffee liquid will not overflow during the freeze-drying process. At the same time, the spacing design between the connecting post 57 and the first silicone ring 56 helps the flow and freeze-drying of the coffee liquid. When the first silicone ring 56, the connecting post 57 and the second silicone ring 58 are pulled out from the inside of the container 51, the freeze-dried coffee liquid can be taken out.

[0034] Workflow: When freeze-drying various flavors of coffee liquid, each flavor is filled into the container 51. Before this, the first silicone ring 56, connecting post 57, and second silicone ring 58 are installed into their respective container 51s. The outermost first silicone ring 56 is placed inside the outermost container 51. By pushing the second silicone ring 58, the connecting post 57 and the first silicone ring 56 move forward until the second silicone ring 58 is completely inside the container 51. At this point, there is a certain gap between the outermost connecting post 57 and the outermost container 51. Both the first silicone ring 56 and the second silicone ring 58 are made of silicone. Coffee liquid is filled between the first silicone ring 56 and the second silicone ring 58. The first silicone ring 56 and the second silicone ring 58 prevent liquid from flowing out. The threaded hole on the inner side of the baffle 52 is aligned with the threaded hole on the ear seat 54, and then fixed with bolts. 53. At this time, the silicone plug 3 is used to seal the operation port at the rear end of the freeze-drying equipment body 1. The freeze-drying equipment body 1 freezes the coffee liquid. The baffle 52 serves to fix and support the multiple containers 51. At the same time, the baffle 52 has gaps inside to facilitate gas flow. There is a gap between the outermost plate 55 and the middle container 51, which allows the cold source to contact the coffee liquid. At the same time, the controller 2 controls the servo motor 41 to start. The servo motor 41 drives the extension fixing column 44, the fixing plate 42 and the extension frame 43 to rotate through the main shaft. The extension frame 43 drives the freeze-drying rack assembly 5 to rotate as a whole. At this time, the coffee liquid in the multiple containers 51 begins to flow, realizing the effect of rapid freeze-drying of coffee liquid. The device rotates the containers 51 to make the coffee liquid flow, preventing some coffee liquid from contacting the cold source too slowly, which would result in a slow freeze-drying speed. At the same time, it improves the uniformity and quality of coffee liquid freeze-drying.

[0035] After freeze-drying, when taking out different flavors of coffee liquid, pull out the silicone stopper 3, and then pull out the second silicone ring 58 one by one. Place it at the lower rear end of the container 51 through the existing hopper. During the process of pulling out the second silicone ring 58, the second silicone ring 58 will drive the first silicone ring 56 to scrape off the coffee liquid inside the container 51 through the connecting post 57. This improves the convenience of taking out the coffee liquid. By scraping the inside of the container 51, the freeze-dried coffee liquid adhering to the inner wall of the container 51 can be removed, improving the practicality of the device.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
