Description

Technical Field

[0001] The utility model relates to the technical field of coffee powder pre-wetting, in particular to a coffee powder pre-wetting device. Background Art

[0002] In traditional coffee brewing methods, coffee powder is directly contacted with hot water for brewing. However, this method may lead to uneven extraction of coffee powder, with some coffee powder being over-extracted and producing a bitter taste, while another part is under-extracted, affecting the overall taste and flavor of coffee. To solve this problem, coffee powder pre-wetting technology has gradually received attention.

[0003] Pre-wetting, also known as pre-soaking, is a process of pre-wetting coffee powder in a specific way before the actual coffee extraction begins. The purpose of this step is to enable each coffee powder particle to evenly contact with water, facilitating the subsequent extraction process.

[0004] However, most of the existing coffee powder pre-wetting methods rely on manual operation, making it difficult to evenly pre-wet coffee powder, resulting in unstable pre-wetting effects and affecting coffee quality. In addition, the use of some manual pre-wetting tools is also relatively cumbersome and not convenient for widespread application in coffee making.

[0005] Therefore, we propose a coffee powder pre-wetting device to solve the problems mentioned above. Content of the Utility Model

[0009] To achieve the above purpose, the present utility model provides the following technical solution: A coffee powder pre-wetting device includes a frame body. Both the left and right ends of the frame body are slidably installed with bearing plates left and right. A holding rack is installed between the left and right bearing plates, and a filter paper is placed inside the holding rack;

[0010] A shaking assembly is installed at the left end of the bearing plate on the left side. The shaking assembly is used to drive the holding rack to move left and right;

[0011] An electric push rod is fixedly installed at the upper end of the frame body, and the output end of the electric push rod is fixedly connected to a pre-wetting assembly. The pre-wetting assembly is used for coffee powder pre-wetting operations.

[0012] Further, feet are fixedly installed at equal angles on the side of the rack, a handle is fixed to the front side of the rack, the side of the rack is in concave-convex fit with the connecting rod, and the connecting rod is fixed to the upper end of the bearing plate close to the rack side.

[0013] Through the above technical solution, the rack is supported by the feet, and the rack can be taken by the handle.

[0014] Further, the shaking assembly includes a fixed frame fixed to the upper left side of the frame body and a movable plate fixed to the left end of the bearing plate on the left side. A rotating rod is installed on the middle part of the fixed frame by bearings, and a movable rod is fixed to the upper end of the rotating rod. A roller is rotatably installed above one end of the movable rod, and the roller is attached to the inner wall of the chute. The chute is penetrated and opened inside the movable plate.

[0015] Through the above technical solution, after the rotating rod rotates, the roller can be driven to rotate by the movable rod.

[0016] Further, the rotating rod and the roller are eccentrically arranged, and the chute is rectangularly arranged.

[0017] Through the above technical solution, the roller can slide inside the chute, thereby driving the movable plate to displace.

[0018] Further, the pre-wetting assembly includes a cavity fixed to the output end of the electric push rod. A liquid injection pipe is communicated with the rear end of the cavity, a liquid outlet pipe is communicated and installed at the lower end of the cavity, a pre-wetting plate is hermetically connected to the lower end of the liquid outlet pipe, and water outlet holes are equally spaced at the lower end of the pre-wetting plate.

[0019] Through the above technical solution, the existing water supply equipment can pre-wet the coffee powder through the water outlet holes.

[0020] Further, an impeller is fixed to the middle of the upper end of the pre-wetting plate, and the impeller is arranged inside the liquid outlet pipe.

[0021] Through the above technical solution, when hot water flows in the liquid outlet pipe, the pre-wetting plate can be driven to rotate by the impeller.

[0022] 3. Beneficial effects:

[0023] Adopting the technical solution provided by the present invention, compared with the prior art, the coffee powder pre-wetting device of the present invention shakes the coffee powder in the filter paper through the shaking assembly, promotes the uniform distribution of the coffee powder, avoids affecting the subsequent extraction effect of the coffee powder, and at the same time has a good pre-wetting uniformity effect and is relatively convenient to operate. The specific content is as follows:

[0024] Place the filter paper in the holding rack, then pour the coffee powder into the filter paper. Subsequently, place the holding rack above the left and right bearing plates, and then start the motor at the lower end of the rotating rod. The motor drives the rotating rod to rotate, and the rotating rod drives the roller to rotate around the center of the rotating rod through the movable rod. During the rotation of the roller, by virtue of the fitting action with the chute and the fitting action between the bearing plate and the frame body, the frame body is driven to move left and right, promoting the uniform distribution of the coffee powder in the filter paper, avoiding the situation of excessive or insufficient accumulation of coffee powder in some areas, enabling hot water to penetrate more fully into the coffee powder, ensuring that each coffee powder can be properly moistened, improving the consistency of brewing, and enhancing the overall taste and flavor of the coffee;

[0025] Connect the existing water supply device to the liquid injection pipe. When it is necessary to pre-wet the coffee powder, the water supply device sends hot water into the cavity through the liquid injection pipe, and then enters the pre-wetting plate through the liquid outlet pipe. The pre-wetting plate pre-wets the coffee powder in the filter paper through the water outlet openings evenly arranged at the lower end. When the hot water flows through the impeller in the liquid outlet pipe, it drives the impeller to rotate. During the rotation of the impeller, the pre-wetting plate is driven to rotate synchronously, improving the uniform pre-wetting effect. The operation is relatively convenient and is conducive to wide use. Description of the Drawings
