Description

Technical Field

[0001] This utility model relates to the field of coffee bean processing technology, specifically to an automated raw material drying device for coffee bean processing. Background Technology

[0002] Coffee beans are the seeds of the coffee plant, which are roasted and used to make coffee beverages. The type, quality, and processing method of coffee beans all affect the final taste of the coffee. Coffee beans should be stored in a dry, cool place, avoiding direct sunlight and humid environments. During the coffee bean processing, they are first processed and dried before use, usually using a drying device.

[0003] An automated raw material drying device for coffee bean processing, disclosed in Chinese Patent Publication No. CN217065338U, uses a rotating rod to drive a turntable to rotate. A threaded rod on the lower side of the turntable is threadedly connected to a sleeve. A telescopic rod is connected to both the sleeve and the mounting frame. Under the limiting action of the telescopic rod, the rotation of the turntable causes the threaded rod and the sleeve to extend and retract threadedly, thereby moving the cover plate. By manually adjusting the locking block into the slot, and manually rotating the cover plate, the locking block is pushed into the second annular groove to seal the drying barrel, allowing the coffee beans to dry in a sealed manner inside the drying barrel, resulting in faster drying. However, the overall flexibility of the raw material drying device for coffee bean processing is low, and coffee beans tend to accumulate inside the drying barrel, making it impossible to effectively and comprehensively dry the coffee beans, thus affecting the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to provide an automated raw material drying device for coffee bean processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated raw material drying device for coffee bean processing, comprising a working chamber, a sealing cover installed at the top of the working chamber, a first rotating mechanism located at the middle of the bottom of the working chamber, a support frame located at the top of the first rotating mechanism, a second rotating mechanism located at the middle of the top of the sealing cover, a material layer located inside the working chamber, and heating plates installed on both sides inside the working chamber.

[0006] Preferably, a door is installed on one side of the outside of the working chamber, and support blocks are evenly and uniformly fixedly connected to the bottom of the inside of the working chamber.

[0007] Preferably, the first rotating mechanism includes a first motor installed at the middle position inside the bottom of the working chamber, a connecting seat installed at the output shaft end of the first motor, and insert rods fixedly connected to the four sides of the top of the connecting seat. Insert holes for inserting into the insert rods are evenly arranged at equal intervals at the middle position of the bottom of the support frame.

[0008] Preferably, positioning rods are evenly and uniformly fixedly connected to the top of the support frame, and positioning holes that engage with the positioning rods are evenly and uniformly arranged at the bottom of the support frame.

[0009] Preferably, the second rotating mechanism includes a second motor installed at the middle position of the top of the sealing cover, a connecting rod installed at the output shaft end of the second motor, a rotating shaft rotatably connected at the middle position inside the bracket, a connecting groove fixedly connected at the middle position of the bottom end of the rotating shaft, a rotating rod fixedly connected at the top end of the rotating shaft, a connecting block that engages with the connecting rod fixedly connected at the middle position of the top end of the rotating rod, and actuating blades fixedly connected to both sides of the outside of the rotating rod.

[0010] Preferably, the material layer includes a heat-conducting layer disposed inside the working chamber, a heat-insulating layer disposed outside the heat-conducting layer, and a protective layer disposed outside the heat-insulating layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This automated raw material drying device for coffee bean processing heats and dries coffee beans in a tray by installing an electric heating plate inside the working chamber. Simultaneously, the first motor at the bottom of the working chamber starts and drives the tray to rotate via a connecting seat, thereby ensuring uniform heating of the tray's exterior. The second motor at the top of the sealing cover starts and drives a rotating rod and a stirring blade to rotate in opposite directions inside the tray via a connecting rod, effectively moving the coffee beans within the tray, ensuring uniform drying of the coffee beans, and improving the overall performance of the drying device.

[0013] 2. This automated coffee bean processing raw material drying device features a heat-conducting layer, a heat-insulating layer, and a protective layer within its working chamber. The heat-conducting layer, made of aluminum alloy, effectively transfers heat. An insulation layer outside the heat-conducting layer effectively isolates the external temperature, reducing heat loss. The outermost protective layer ensures the strength and corrosion resistance of the drying device. Furthermore, multiple sets of through-holes on the support frame evenly distribute hot air, ensuring that hot air penetrates every corner of the coffee beans during the drying process. The use of multiple layers not only improves the efficiency and performance of the coffee bean drying device but also increases its durability and overall stability. Attached Figure Description

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.

[0021] Please see Figure 1-5 This utility model provides two technical solutions:

[0022] Example 1: An automated raw material drying device for coffee bean processing includes a working chamber 1, a sealing cover 2 installed at the top of the working chamber 1, a first rotating mechanism 3 located at the middle of the bottom of the working chamber 1, a support frame 4 located at the top of the first rotating mechanism 3, a second rotating mechanism 5 located at the middle of the top of the sealing cover 2, a material layer 8 inside the working chamber 1, and electric heating plates 9 installed on both sides inside the working chamber 1. The electric heating plates 9 can dry and heat the coffee beans in the support frame 4.

[0023] A door 101 is installed on one side of the exterior of the working chamber 1. Support blocks 102 are evenly and uniformly fixedly connected to the bottom of the interior of the working chamber 1. The door 101 can be opened to clean and maintain the interior of the working chamber 1. At the same time, the support blocks 102 can effectively support the bottom support frame 4 inside the working chamber 1.

[0024] The first rotating mechanism 3 includes a first motor 301 installed at the middle position inside the bottom of the working chamber 1. A connecting seat 302 is installed at the output shaft end of the first motor 301. Insert rods 303 are fixedly connected to the four sides of the top of the connecting seat 302. Insert holes 401 that engage with the insert rods 303 are evenly arranged at equal intervals at the middle position of the bottom of the support frame 4. When the first motor 301 is started, it can drive the support frame 4 to rotate through the connecting seat 302.

[0025] Positioning rods 402 are evenly and uniformly fixedly connected to the top of the bracket 4. Positioning holes 403 that engage with the positioning rods 402 are evenly and uniformly arranged at the bottom of the bracket 4. The positioning rods 402 and positioning holes 403 at the top and bottom of the bracket 4 respectively facilitate the interlocking of similar brackets 4.

[0026] The second rotating mechanism 5 includes a second motor 501 installed at the middle position of the top of the sealing cover 2. A connecting rod 502 is installed at the output shaft end of the second motor 501. A rotating shaft 6 is rotatably connected to the middle position inside the tray 4. A connecting groove 601 is fixedly connected to the middle position of the bottom end of the rotating shaft 6. A rotating rod 602 is fixedly connected to the top end of the rotating rod 602. A connecting block 603 that engages with the connecting rod 502 is fixedly connected to the middle position of the top end of the rotating rod 602. A toggle blade 7 is fixedly connected to both sides of the outside of the rotating rod 602. When the second motor 501 is started, it can drive the connecting rod 502 to rotate. At this time, the connecting rod 502 can drive the rotating rod 602 and the toggle blade 7 to rotate inside the tray 4 through the connecting block 603, thereby toggle the coffee beans inside the tray 4.

[0027] Example 2 differs from Example 1 mainly in that:

[0028] An automated coffee bean processing raw material drying device includes a heat-conducting layer 801 disposed inside the working chamber 1 in the material layer 8. The heat-conducting layer 801 is an aluminum alloy layer with good thermal conductivity, which can effectively transfer heat and improve the efficiency of the drying process.

[0029] A heat insulation layer 802 is provided on the outside of the heat-conducting layer 801. The heat insulation layer 802 is made of aluminum silicate fiber, which can effectively isolate the external temperature, reduce heat loss, improve energy utilization, and reduce energy consumption.

[0030] The heat insulation layer 802 is provided with a protective layer 803 on the outside. The protective layer 803 is made of stainless steel, which increases corrosion resistance, provides structural strength, prevents excessive heat loss, and keeps heat concentrated in the dry area. At the same time, all contents not described in detail in this specification are prior art known to those skilled in the art.

[0031] In this embodiment, the coffee bean trays 4 are stacked inside the working chamber 1, and the insertion rod 303 at the top of the first rotating mechanism 3 is inserted into the insertion hole 401 on the bottom tray 4. At this time, the positioning rod 402 at the top of the tray 4 is inserted into the positioning hole 403 at the bottom of the tray 4, thus completing the installation of the tray 4. The connecting block 603 at the top of the tray 4 can be inserted into the connecting groove 601 at the bottom of the tray 4. At this time, the sealing cover 2 is installed at the top of the working chamber 1, and the connecting rod 502 at the middle position of the top of the sealing cover 2 can be inserted into the connecting block 603 on the top tray 4. At this time, the first rotating mechanism 3 is activated to drive the tray 4 to rotate, and with the help of the heating plate 9, the tray 4 can be heated evenly. At the same time, the second rotating mechanism 5 is activated to drive the agitator 7 to rotate inside the tray 4, thereby moving the coffee beans inside the tray 4 in the opposite direction, effectively drying the coffee beans.
