Description

Technical Field

[0001] The utility model relates to the technical field of coffee grounds purification, in particular to a coffee grounds purification device. Background Art

[0002] Instant coffee is a common food ingredient in the market. This product is mainly made from coffee beans, which are processed through roasting, grinding, extraction, concentration, spray drying and other processes. The yield of instant coffee produced from roasted coffee beans is generally 30-55%, and 45-70% of dry matter is discharged with coffee grounds, which means that a large amount of coffee grounds will be generated during the production process.

[0003] Generally, fresh coffee grounds contain 68% water, 3.7% fat, 4.2% protein, and 0.15% ash. The fat content in instant coffee is less than 1%, which means that most of the fat (coffee oil) is discharged with the coffee grounds. Tests show that when we dry fresh coffee grounds, the fat content in the dried coffee grounds is greater than 10%. At the same time, coffee grounds contain a large amount of carbohydrates such as lignin, fiber, and water-insoluble polysaccharides, which provide a substrate for the preparation of flavor substances. However, the existing coffee grounds extraction equipment generally directly extracts the coffee grounds during extraction, and the coffee grounds particles are large, which will affect the subsequent extraction equipment to extract the coffee grounds.

[0004] So we proposed a coffee grounds purification device to solve the above problems. Utility Model Content

[0009] A receiving assembly is threadedly mounted on the lower end of the filter cartridge, and a plurality of filter plates are fixedly mounted at equal angles inside the filter cartridge, a bottom plate is fixedly mounted between the bottoms of the plurality of filter plates, and a driving mechanism is mounted on the upper end of the bottom plate, while an extrusion assembly is sleeved on the outer side of the driving mechanism, and the driving mechanism is used to drive the extrusion assembly to rotate forward and reversely.

[0011] Through the above technical solution, the filter can be disassembled by rotating the mounting ring to take out the filtered coffee grounds.

[0012] Furthermore, the interior of the filter plate is of a hollow design, and a drainage port is provided at the lower end of the filter plate.

[0013] Through the above technical solution, the filtrate squeezed out from the coffee grounds under the action of the squeezing plate can fall into the distillation tank through the discharge port of the filter plate.

[0014] Furthermore, the driving mechanism includes an electric push rod fixed to the upper end of the bottom plate, a movable plate is fixed to the output end of the electric push rod, and a driving block is fixed to the side of the movable plate.

[0015] Through the above technical solution, when the electric push rod is started, the movable plate can be driven to move up and down.

[0016] Furthermore, the extrusion assembly includes a sleeve mounted on the outside of the driving mechanism, the lower end bearing of the sleeve is installed above the base plate, the upper end of the sleeve is fixed with a guide cone block, and the side of the sleeve is fixed with a plurality of extrusion plates, and the extrusion plates are arranged one by one with the filter plates.

[0017] Through the above technical solution, the sleeve, the extrusion plate and the guide cone block can rotate synchronously.

[0018] Furthermore, the end of the driving block is fitted into the interior of the driving groove, and the driving groove is spirally opened on the inner wall of the sleeve, and a spring sheet is fixed to the lower end of the guide cone block.

[0019] Through the above technical solution, the sleeve can be driven to rotate by utilizing the cooperation between the driving groove and the driving block.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the coffee grounds purification device of the utility model adopts the technical solution provided by the utility model. After the coffee grounds are finely ground by the grinding component, the coffee grounds are efficiently filtered by the extrusion component, thereby improving the extraction effect of the subsequent extraction equipment on the coffee grounds. The specific contents are as follows:

[0022] The coffee grounds are poured into the upper end of the frame through the feed port at the upper end of the frame, and the coffee grounds are ground finer by the grinding assembly. At the same time, warm water can be added during the grinding process. The ground coffee grounds fall into the interior of the filter cartridge and fall on the top of the filter screen. The electric push rod is started, and the electric push rod drives the driving block to slide inside the driving groove through the movable plate, thereby driving the extrusion assembly to rotate above the bottom plate, that is, driving the extrusion plate to rotate above the filter screen, so that the coffee grounds on the filter screen can promote the slurry to quickly pass through the filter plate and the filter screen under the cooperation of the extrusion plate and the filter plate, so as to obtain slurry without more impurities. The filtered slurry then falls into the distillation tank for distillation, and then the rectified slurry is allowed to stand, the upper liquid is collected, and then the existing purification equipment is used to purify the clean slurry;

[0023] When the driving mechanism drives the sleeve and the guide cone block to rotate, the reed at the lower end of the guide cone block will be driven to rotate synchronously. During the rotation of the reed, the filter plate will be struck to shake off the coffee grounds adhered to the filter plate, thereby improving the filtering effect of the coffee grounds.
