AI Technical Summary
In existing coffee beverage production equipment, coffee liquid containing viscous components tends to accumulate in the filter plate pores, leading to increased pressure in the feed hopper and blockage at the discharge port, thus affecting feeding efficiency.
It adopts a double-layer inclined filter assembly, including a fine filter and a coarse filter, combined with a cleaning shaft and a drive unit. The cleaning shaft is driven by the drive seat to move, and the cleaning structure scrapes the impurities on the surface of the filter screen. Combined with the sealing assembly, it ensures the sealing of the opening groove and prevents clogging.
It effectively classifies and intercepts viscous impurities of different particle sizes, reduces filter clogging, ensures stable feeding efficiency of the high-pressure pump, avoids damage to the seal, and ensures the continuity of the feeding process.

Abstract
Claims
1. A homogenizing device for coffee beverage production, characterized in that: include A processing table (11) is provided with a feeding bin (12). A filter assembly (2) is disposed in the feed hopper (12). The filter assembly (2) includes a filter section installed inside the feed hopper (12) and in an inclined state. The filter section includes a lower fine filter screen (21) and an upper coarse filter screen (22). A cleaning shaft (29) for cleaning the filter screen is disposed in the interlayer space between the fine filter screen (21) and the coarse filter screen (22). A drive unit for driving the cleaning shaft (29) is installed on the side of the feed hopper (12). The drive unit includes a drive seat (25) that slides along the inclined direction of the filter screen. The drive seat (25) is connected to the cleaning shaft (29) through a connecting shaft (28). An opening groove for displacement of the connecting shaft (28) is opened on the side of the feed hopper (12). A sealing assembly (3) for sealing the opening groove is sleeved on the connecting shaft (28).
2. A homogenisation apparatus for the production of a coffee beverage according to claim 1, characterised in that: The edges of the two filter screens are rigidly connected by a stainless steel rod to form a stable sandwich structure. The surface of the cleaning shaft (29) is symmetrically welded with two sets of silicone scrapers (291), and the edges are designed with bevels.
3. A homogenisation apparatus for the production of a coffee beverage according to claim 2, characterised in that: The feed bin (12) is inclined towards the lower side of the filter assembly (2), and a discharge plate (121) for discharging filtered impurities is embedded therein. The installation position of the discharge plate (121) corresponds to the interlayer space between the fine filter screen (21) and the coarse filter screen (22), and is located at the lowest end of the inclination angle of the two sets of filter screens.
4. A homogenisation apparatus for the production of a coffee beverage according to claim 3, characterised in that: The inner side of the discharge plate (121) is provided with a protrusion that matches the filter screen interlayer space. The protrusion has a wedge-shaped structure and is consistent with the inclination angle of the filter screen. The corresponding side of the feed hopper (12) is provided with a rectangular slag discharge port that is perfectly matched with the size of the protrusion. The length of the long side of the slag discharge port is slightly greater than the width of the two sets of filter screens.
5. A homogenization device for the production of coffee beverages according to claim 3, characterized in that: The edge of the discharge plate (121) is evenly distributed with threaded holes, and is tightly connected to the outer wall of the feed hopper (12) by bolts. A ring of nitrile rubber with an O-shaped cross section is embedded on the contact surface between the protrusion and the slag discharge port.
6. A homogenization device for the production of coffee beverages according to claim 1, characterized in that: In the initial state, the cleaning unit is positioned in the right-side standby position of the feed hopper (12).
7. A homogenizing device for the production of coffee beverages according to claim 1, characterized in that: The sealing assembly (3) includes a sealing plate (31) that is movably sleeved on the horizontal section of the connecting shaft (28). The sealing plate (31) is adapted to the size of the opening groove. A sealing ring is provided at the contact position between the sealing plate (31) and the opening groove. The sealing plate (31) is movably sleeved on the connecting shaft (28) through a fixing sleeve (32). A slide bar protrudes from the inner wall of the fixing sleeve (32) toward the position of the connecting shaft (28). A slide groove corresponding to the slide bar is opened on the horizontal section of the connecting shaft (28). A handle (34) is fixedly installed on the outer side of the sealing plate (31).
8. A homogenisation apparatus for the production of a coffee beverage according to claim 7, characterised in that: The fixed sleeve (32) is threaded with a butterfly locking member (33). The locking member (33) passes through the fixed sleeve (32) and can be connected to the threaded hole on the connecting shaft (28). The horizontal section of the connecting shaft (28) is provided with two sets of holes that are adapted to the locking member (33). The first hole corresponds to the sealing state in which the sealing plate (31) completely blocks the opening groove, and the second hole corresponds to the working state in which the sealing plate (31) is dislodged from the opening groove. There is an axial distance between the two holes.
