Description

Technical Field

[0001] This invention relates to an automatic processing device for fruit beverages. Background Technology

[0002] Fruit beverages, also known as fruit juice beverages, are juice products obtained from fruits through physical crushing, pressing, centrifugation, and other processes. Currently, most fruit juicing equipment on the market uses rotary blade crushing or screw head extrusion. Screw head extrusion not only enables continuous juice production but also promptly removes the resulting pulp. However, in existing screw extrusion processes, the separation of juice and pulp is usually achieved through a filter screen mounted on the outside of the screw head. Furthermore, the particle size of the pulp formed by screw extrusion is difficult to control, inevitably leading to filter screen clogging and affecting juice extraction. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic processing equipment for fruit beverages that can simultaneously perform multiple functions such as juicing, slag discharge and feeding, and filter cartridge self-cleaning. The self-cleaning structure is simple, the processing cost is low, and the juicing processing efficiency is effectively improved.

[0004] The technical solution to achieve the above objective is: an automatic processing device for fruit beverages, comprising a differentially rotating screw extruder and a filter cartridge assembly, wherein the filter cartridge assembly is coaxially sleeved outside the screw extruder, wherein:

[0005] The filter cartridge assembly includes a cylinder, and N drainage annular grooves are equally spaced on the outer wall of the cylinder. A filter hole with an opening facing the inside of the cylinder is provided between each two adjacent drainage annular grooves.

[0006] Each filter hole is connected to the adjacent drain ring groove through a guide hole, and the diameter of the guide hole decreases sequentially from the side where the filter hole is located to the side where the drain ring groove is located. Each guide hole is arranged along the axial direction of the cylinder.

[0007] A rotating rod is coaxially inserted through all the guide holes located on the same straight line. The two ends of the rotating rod extend to the outside of the cylinder. The rotating rod rotates with the cylinder and rotates on its own axis. The diameter of the rotating rod is smaller than the minimum diameter of the guide hole.

[0008] Multiple scrapers are fixed on the outer wall of the rotating rod, and all the scrapers on the rotating rod are located in all the filter holes adjacent to the rotating rod.

[0009] In the aforementioned automatic processing equipment for fruit beverages, each drainage ring groove is provided with a mounting ring that can slide back and forth along its axial direction. Multiple push sleeves are evenly spaced and fixed through each mounting ring. The multiple push sleeves on each mounting ring extend into multiple guide holes on the same circumference adjacent to it, and each push sleeve is fitted outside the corresponding rotating rod.

[0010] In the above-mentioned automatic processing equipment for fruit beverages, a mating groove is provided on the inner wall of the push sleeve, and a limiting protrusion that slides into the mating groove is fixed on the outer wall of the rotating rod. The mating groove includes two arc-shaped grooves and two inclined grooves that are staggered end to end. The two arc-shaped grooves are staggered along the axial direction of the push sleeve, and the two inclined grooves are symmetrically arranged along the central axis of the push sleeve.

[0011] In the aforementioned automatic processing equipment for fruit beverages, multiple guide rods are evenly fixed in the drain ring groove, each guide rod being arranged along the axial direction of the drain ring groove, and each guide rod slidingly passing through the corresponding mounting ring.

[0012] In the aforementioned automatic fruit beverage processing equipment, the two ends of the cylinder are rotatably connected to a feed guide cylinder and a discharge guide cylinder, and the two ends of each rotating rod are engaged with the outer sides of the feed guide cylinder and the discharge guide cylinder, respectively.

[0013] The aforementioned automatic fruit beverage processing equipment further includes a mounting housing capable of accommodating the screw extrusion rod and filter cartridge assembly, wherein the feed guide cylinder and the discharge guide cylinder are fixed to the two ends of the mounting housing in a one-to-one correspondence.

[0014] The above-mentioned automatic processing equipment for fruit beverages includes a differential drive mechanism fixed at one end of the mounting shell, a slag discharge port communicating with the discharge guide cylinder at the other end, and a liquid discharge port at the bottom of the mounting shell.

[0015] In the aforementioned automatic fruit beverage processing equipment, a drive rack is rotatably mounted inside the mounting housing, and the drive rack is meshed with the outer wall of the cylinder.

[0016] The aforementioned automatic processing equipment for fruit beverages includes a differential drive mechanism comprising a large gear and a small gear meshing with each other, wherein the large gear is coaxially fixed with a spiral extrusion rod, and the small gear is coaxially fixed with a drive rack.

[0017] In the aforementioned automatic processing equipment for fruit beverages, both ends of the cylinder are provided with outwardly extending protruding rings, and two arc-shaped support plates are fixed at the bottom of the inner side of the mounting shell. The protruding rings at both ends of the cylinder are slidably engaged with the two arc-shaped support plates, the drain port is located between the two arc-shaped support plates, and the drive rack is provided with a clearance ring groove that engages with the protruding rings.

[0018] The advantages of the automatic fruit beverage processing equipment of the present invention compared with the prior art are mainly reflected in:

[0019] (1) In the automatic processing equipment of the present invention, a differentially rotating spiral extrusion rod and a filter cylinder assembly are provided. On the one hand, the spiral extrusion rod can effectively realize the extrusion and juicing of fruit and the discharge and feeding of residue. On the other hand, the filter cylinder assembly changes the flow direction of the juice through the connection of the discharge ring groove, filter hole and guide hole. On this basis, a rotating rod that can cooperate with multiple filter holes in sequence is provided. Each rotating rod disperses the fruit residue blocked in the filter hole by its own rotation. At the same time, the rotation of the entire cylinder allows the dispersed fruit residue to be released from the filter hole, thereby effectively avoiding the blockage of the entire filter cylinder assembly and improving the juicing processing efficiency.

[0020] (2) The guide hole is set as a conical structure with its diameter decreasing from the side where the filter hole is located to the side where the drain ring groove is located, and a push sleeve that can be pushed back and forth in the guide hole is also provided to further avoid the blockage of the guide hole.

[0021] (3) An installation ring for installing the push sleeve is set in the drain ring groove, and a matching groove and a limiting protrusion for driving the push sleeve to reciprocate are set on the inner wall of the push sleeve and the outer wall of the rotating rod, so as to effectively realize the linkage between the rotation of the rotating rod and the movement of the push sleeve, thus eliminating the need to set up an additional anti-blocking drive structure.

[0022] (4) Feed guide cylinder and discharge guide cylinder are rotatably fitted at both ends of the cylinder, and the two ends of the rotating rod extend outward and mesh with the outside of the feed guide cylinder and the discharge guide cylinder, so that the rotation of the entire cylinder and the meshing action can drive each rotating rod to rotate synchronously; in addition, the differential rotation of the entire cylinder and the spiral extrusion rod is achieved by the differential drive mechanism. Based on this, the automatic processing equipment of the present invention only needs to be set with one drive motor to realize multiple functions such as extrusion and juicing, slag discharge and feeding, and filter cartridge self-cleaning.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0033] Example 1:

[0034] Please see Figures 1 to 5 According to an embodiment of the present invention, an automatic fruit beverage processing device is mainly used for the juicing production of fruit juice beverages, and specifically includes a mounting shell 200, a differential drive mechanism, a screw extrusion rod 1, and a filter cartridge assembly 100. The filter cartridge assembly 100 is coaxially sleeved on the outside of the screw extrusion rod 1. The screw extrusion rod 1 and the filter cartridge assembly 100 rotate at different speeds through the differential drive mechanism.

[0035] Please see again Figure 2 The filter cartridge assembly 100 includes a feed guide cylinder 130 and a discharge guide cylinder 140 respectively fixed to both ends of the mounting housing 200, and also includes a cylinder body 110 rotatably assembled between the feed guide cylinder 130 and the discharge guide cylinder 140.

[0036] A feed hopper penetrating the mounting housing 200 can be provided at the top of the feed guide cylinder 130 to guide the fruit to be processed into the cylinder 110. A slag discharge port communicating with the discharge guide cylinder 140 is provided at the end of the mounting housing 200 to discharge the fruit slag generated in the cylinder 110.

[0037] The cylinder 110 is coaxially sleeved on the outside of the spiral extrusion rod 1, and both ends of the cylinder 110 are provided with outwardly extending protruding rings 118. The bottom of the inner side of the mounting shell 200 is fixed with two arc-shaped support plates 204. The protruding rings 118 at both ends of the cylinder 110 are slidably engaged with the two arc-shaped support plates 204 in a corresponding manner. A drain port located between the two arc-shaped support plates 204 is also provided at the bottom of the mounting shell 200.

[0038] Both the cylinder 110 and the screw extrusion rod 1 are connected to a differential drive mechanism, so that the fruit raw material can be effectively extruded by the screw after entering the cylinder 110 through the feed guide cylinder 130. The juice produced by extrusion is filtered through the cylinder 110 into the area between the two arc-shaped support plates 204 and discharged through the drain port; the fruit residue is guided into the discharge guide cylinder 140 by the screw extrusion rod 1 and discharged through the residue discharge port at the end of the housing 200.

[0039] In this embodiment, please refer to again Figure 1 , Figure 2 and Figure 5 A drive rack 201, meshing with the outside of the cylinder 110, is rotatably mounted inside the housing 200. The drive rack 201 has a clearance groove that mates with the extended protruding ring 118. The differential drive mechanism includes a large gear 202 and a small gear 203 that mesh with each other. The large gear 202 is coaxially fixed to the helical extrusion rod 1, and the small gear 203 is coaxially fixed to the drive rack 201. Based on this, a drive motor drives the large gear 202, which is coaxially fixed to the helical extrusion rod 1, thereby rotating the helical extrusion rod 1. Simultaneously, the large gear 202 meshes with and drives the small gear 203 to rotate. The small gear 203 is coaxially fixed to the drive rack 201, thus driving the cylinder 110 to rotate via the drive rack 201. By specifically setting the transmission ratio between the large gear 202 and the small gear 203 to be ≠ the transmission ratio between the drive rack 201 and the cylinder 110, the differential rotation between the cylinder 110 and the spiral extrusion rod 1 can be effectively achieved.

[0040] Example 2

[0041] Example 2 further optimizes the structure of the filter cartridge assembly 100 based on Example 1.

[0042] Please see again Figure 2The filter cartridge assembly 100 includes a feed guide cylinder 130 and a discharge guide cylinder 140 respectively fixed to both ends of the mounting housing 200, and also includes a cylinder body 110 rotatably assembled between the feed guide cylinder 130 and the discharge guide cylinder 140.

[0043] Please see again Figure 2 and Figure 5 N drainage ring grooves 111 are equally spaced on the outer wall of the cylinder 110. Each pair of adjacent drainage ring grooves 111 is provided with a filter hole 112 with an opening facing the inside of the cylinder 110. Each filter hole 112 is connected to the adjacent drainage ring groove 111 through a guide hole 113, and the diameter of the guide hole 113 decreases from the side where the filter hole is located to the side where the drainage ring groove is located.

[0044] Please see again Figure 4 and Figure 6 Multiple rotating rods 120 are also provided inside the cylinder 110. Each rotating rod coaxially passes through all the guide holes located on the same straight line. Both ends of each rotating rod 120 extend outward and respectively engage with the outer sides of the feed guide cylinder 130 and the discharge guide cylinder 140. The diameter of the rotating rod 120 is smaller than the minimum diameter of the guide hole 113. Scrapers 121 located in the filter holes 112 are also fixed on the outer side of the rotating rod 120. That is, multiple scrapers 121 are fixed on the outer wall of the rotating rod 120, and all the scrapers 121 on the rotating rod are located one-to-one in all the filter holes 112 adjacent to the rotating rod.

[0045] In this embodiment, the fruit raw material is still squeezed and juiced by the differential rotation between the cylinder 110 and the screw extrusion rod 1: the juice flows into the area between the two arc-shaped support plates 204 after passing through the filter hole 112, the guide hole 113 and the discharge ring groove 111 in sequence, and is discharged through the discharge port; the fruit residue is guided into the discharge guide cylinder 140 by the screw extrusion rod 1 and is discharged through the residue discharge port at the end of the housing 200.

[0046] In addition, as the cylinder 110 rotates, it drives multiple rotating rods 120 mounted on it to rotate synchronously. While the rotating rods 120 revolve around the central axis of the cylinder 110, they mesh with the feed guide cylinders 130 and the discharge guide cylinders 140 at both ends, thereby also driving the rotating rods 120 to rotate synchronously. This, in turn, drives the scraper 121 on the surface of the rotating rod 120 to continuously rotate and scrape away the fruit residue blocking the filter holes 112. When a filter hole 112 rotates to the top of the screw extrusion rod 1, its filter hole 112 opening faces downward. At this time, the fruit residue that has been broken up by the scraper 121 in the filter hole 112 can fall off due to its own gravity, thereby detaching from the filter hole 112 and preventing the filter hole 112 from becoming blocked.

[0047] Example 3

[0048] Example 3 is a further optimized structure of the cylinder 110 and the rotating rod 120 based on Example 2.

[0049] Please refer to Figures 4 to 8 Multiple guide rods 117 are evenly fixed in the drain ring groove 111. Mounting rings 114 located in the drain ring groove 111 are slidably sleeved on the guide rods 117, so that the mounting rings 114 can slide back and forth along the axial direction of the cylinder 110 (drain ring groove 111). Push sleeves 115 that can extend into the guide holes 113 are fixed through the mounting rings 114. That is, multiple push sleeves 115 are evenly fixed through each mounting ring 114. The multiple push sleeves 115 on each mounting ring 114 extend into the multiple guide holes 113 on the same circumference adjacent to it, and each push sleeve 115 is sleeved on the outside of the corresponding rotating rod 120.

[0050] Please see again Figure 4 , Figure 6 and Figure 7 A mating groove 116 is provided on the inner wall of the push sleeve 115, and a limiting protrusion 122 that slides into the mating groove 116 is fixed on the outer wall of the rotating rod 120. The mating groove 116 includes two arc-shaped grooves i and two inclined grooves ii that are connected end to end. The two arc-shaped grooves i are offset along the axial direction of the push sleeve 115, and the two inclined grooves ii are symmetrically arranged along the central axis of the push sleeve 115.

[0051] The automatic fruit beverage processing equipment of the present invention, in use, includes a drive motor that drives a large gear 202, which is coaxially fixed with the spiral extrusion rod 1, thereby driving the spiral extrusion rod 1 to rotate. Simultaneously, the large gear 202 meshes with and drives a small gear 203 to rotate. The small gear 203 is coaxially fixed with a drive rack 201, thereby driving the cylinder 110 to rotate via the drive rack 201. Specifically, by setting the transmission ratio between the large gear 202 and the small gear 203 not to be equal to the transmission ratio between the drive rack 201 and the cylinder 110, differential rotation between the cylinder 110 and the spiral extrusion rod 1 can be effectively achieved. During differential rotation, the fruit raw material moves and is extruded between the cylinder 110 and the spiral extrusion rod 1, thereby realizing spiral extrusion juicing and spiral pushing of slag discharge. The fruit juice flows through the filter hole 112, the guide hole 113 and the drain ring groove 111 in sequence and flows into the area between the two arc-shaped support plates 204, and is discharged through the drain port; the fruit pulp is guided into the discharge guide cylinder 140 by the spiral conveying of the spiral extrusion rod 1, and is discharged through the slag discharge port at the end of the housing 200.

[0052] While the cylinder 110 rotates, it drives multiple rotating rods 120 mounted on it to rotate synchronously. As the rotating rods 120 revolve around the central axis of the cylinder 110, they engage with the feed guide cylinders 130 and discharge guide cylinders 140 at both ends, thus also driving the rotating rods 120 to rotate synchronously on their own axis. This, in turn, causes the scrapers 121 on the surface of the rotating rods 120 to continuously rotate and scrape away the fruit residue clogging the filter holes 112. When a filter hole 112 rotates above the screw extrusion rod 1, its opening faces downwards. At this time, the fruit residue dispersed by the scrapers 121 inside the filter hole 112 can fall under its own gravity, thus detaching from the filter hole 112 and preventing clogging.

[0053] While the rotating rod 120 rotates, the limiting protrusion 122 on its surface rotates synchronously. The free end of the limiting protrusion 122 slides in the mating groove 116. Thus, based on the relative sliding between the limiting protrusion 122 and the mating groove 116, the push sleeve 115 can be driven to reciprocate outside the rotating rod 120. Furthermore, the reciprocating movement of the push sleeve 115 can effectively push out the fruit residue blocking the guide hole 113, thereby effectively preventing the guide hole 113 from becoming blocked.

[0054] In summary, the automatic fruit beverage processing equipment of the present invention only requires one drive motor to simultaneously realize multiple functions such as squeezing and juicing, slag discharge and feeding, and filter cartridge self-cleaning, and effectively improves the juicing processing efficiency.

[0055] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
