Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to a pitting and pulping machine. Background Technology

[0002] In the food processing industry, pitting and pulping are key preliminary processes when processing foods with pits. The results of these processes directly affect the quality of subsequent products, production efficiency, and processing costs.

[0003] Currently, most food pitting and pulping operations employ separate processing equipment or semi-mechanized methods. In some processing scenarios, manual pitting is performed first, followed by pulping in a pulping machine. This method not only requires significant labor costs but also suffers from limited manual pitting speed and small batch throughput, resulting in low overall processing efficiency and failing to meet the demands of large-scale industrial production. Other scenarios utilize traditional three-scraper pulping machines, which rely on forced scraping impact, leading to high pitting rates, incomplete pitting (such as residual pit fragments and kernels), and insufficient separation of pulp from pits. This results in the presence of hard impurities in the pulp, affecting product taste and food safety. Furthermore, existing equipment often results in excessive pulp loss during pitting, further reducing raw material utilization. Therefore, current food pitting and pulping technologies suffer from drawbacks such as high pitting rates, low pitting efficiency, poor pitting results, and significant raw material loss, failing to meet the food processing industry's demands for efficient and precise processing.

[0004] In view of the above, this utility model is hereby proposed. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pitting and pulping machine that integrates pre-crushing, pulping, and cold protection of various fruits to meet the needs of pitting, peeling, and kernel removal.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A de-core pulping machine includes a feed hopper, a pre-crushing device, a pulping device, and a slag discharge device, all fixedly mounted on a frame and connected in sequence. The pre-crushing device includes a pre-crushing chamber and a rotatable pre-crushing blade holder fitted inside the pre-crushing chamber. The pulping device includes a pulping chamber, a conical filter screen fixedly mounted inside the pulping chamber, and a pulping blade holder capable of rotating and pulping within the conical filter screen. The feed hopper is fixedly connected to and communicates with one end of the pre-crushing chamber. The other end of the pre-crushing chamber is fixedly connected to the pulping chamber and communicates with one end of the conical filter screen. One side of the slag discharge device is fixedly connected to the other end of the pulping chamber and communicates with the other end of the conical filter screen. A pulp outlet is provided at the bottom of the pulping chamber. A first drive motor is also fixedly mounted on the frame, and the drive shaft of the first drive motor passes through the slag discharge device and is detachably and fixedly connected to the rotating shaft of the pulping blade holder and the rotating shaft of the pre-crushing blade holder in sequence.

[0007] Specifically, the feed hopper is equipped with an auger for conveying materials to the pre-crushing device, and a second drive motor for driving the auger to rotate is fixed on the frame. The drive shaft of the second drive motor passes through one side of the feed hopper and is connected to the rotating shaft of the auger.

[0008] Specifically, the pre-crushing chamber is uniformly provided with wavy ridges along the circumference of its inner wall. The ridges are arranged axially. The pre-crushing blade holder includes a double-disc support frame for fixing the drive shaft of the first drive motor, and multiple axial blades uniformly fixed along the circumference of the double-disc support frame and paired with the ridges for pre-crushing materials. The wavy lines of the axial blades are arranged axially.

[0009] Furthermore, the angle α between the projection of the convex strip located at the twelve o'clock position onto the horizontal plane and the rotation axis of the pre-crushing tool holder is 1.5-2.5°.

[0010] Furthermore, the axial blade includes a corrugated blade and a flat blade, which are circumferentially spaced apart on the double-edged disc support frame.

[0011] Specifically, the small end of the conical filter screen is adapted to the pre-crusher chamber, and the large end is adapted to the slag discharge device.

[0012] Specifically, the shape of the pulping knife holder is adapted to the conical filter screen.

[0013] Furthermore, the pulping blade holder includes a cylindrical support frame for fixing the drive shaft of the first drive motor, and multiple arc-shaped scrapers that are fixed axially along the cylindrical support frame and evenly arranged circumferentially.

[0014] Furthermore, the end of the arc-shaped scraper near the small end of the pulping knife holder has a radial bending angle β of 2-6° relative to the cylindrical support frame, and the end of the arc-shaped scraper near the large end of the pulping knife holder has a radial bending angle γ of 5-12° relative to the cylindrical support frame. The angle θ between the projection of the arc-shaped scraper on the horizontal plane at the twelve o'clock position and the rotation axis of the cylindrical support frame is 1.5-2.5°.

[0015] Specifically, one end of the slag discharge device is a slag discharge chamber adapted to the pulping knife holder, and the other end is fixed with a first bracket for rotating and fixing the drive shaft of the first drive motor. A slag discharge port is provided tangentially to the slag discharge chamber and in the vertical direction.

[0016] Specifically, it also includes a motor connection compartment, which is fixed between the slag discharge device and the first drive motor. A reducer connected to the drive shaft of the first drive motor is also provided on the side of the motor connection compartment near the first drive motor.

[0017] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention utilizes the combined action of convex strips and a high-speed rotating pre-crushing blade holder to pre-crush fruit pits. The structural design of the pulping blade holder and conical filter screen, along with the high-speed rotation of the pulping blade holder and the arc-shaped scraper creating a high-speed vortex flow semi-fluid, leverages fluid impact force to achieve efficient separation of pulp and hard materials like pits. This fundamentally changes the traditional pitting and pulping method. It effectively overcomes the shortcomings of traditional pulping machines, such as high pitting rate, low pitting rate, and low processing capacity caused by forced scraper impact. Pitting efficiency can reach ≥98%, and single-machine capacity is increased to 5-12 tons / day, significantly enhancing the continuity and economy of fruit processing.

[0018] Furthermore, this utility model equipment integrates functions such as fruit pre-crushing, pulping, pitting, peeling, and kernel removal, consolidating multiple scattered processes in traditional processing into an integrated process, significantly shortening the production process, effectively improving processing efficiency, and greatly reducing the production costs of enterprises.

[0028] Furthermore, the angle α between the projection of the protrusion 311 located at the twelve o'clock position onto the horizontal plane and the rotation axis of the pre-crushing tool holder 32 is 1.5-2.5°.

[0029] Furthermore, the axial blade 322 includes a corrugated blade and a flat blade, which are circumferentially spaced apart on the double-edged disc support frame 321. (See [reference]) Figure 8 and 9 As shown.

See [reference needed]. Figure 13-15 As shown.

[0034] Specifically, one end of the slag discharge device 5 is a slag discharge chamber 51 adapted to the pulping blade holder 43, and the other end is fixed with a first bracket for rotating and fixing the drive shaft of the first drive motor 6.

[0036] This embodiment also provides a method for using a pitting and pulping machine, as detailed below: The fruit to be processed (pitted or peeled) is placed into the feed hopper 2 and fed into the pre-crushing device 3 by the auger 21. Under the dual action of the protruding strips 311 and the high-speed rotating pre-crushing blade holder 32, the fruit pits are pre-crushed. Because the protruding strips 311 have a certain inclination angle, the crushed fruit enters the pulping device 4 from the small end of the pulping blade holder 43. Under the dual action of the high-speed rotation of the pulping blade holder 43 and the arc-shaped scraper 432, that is, under the combined action of centrifugal force and the arc-shaped scraper 432, the fruit is further crushed. Under the combined action of the local vortex flow, the pulp, pomace and pits roll in a circular motion within the blade cavity. The particles impact each other at high speed in the high-speed vortex, causing the smaller pulp particles with lower specific gravity to pass through the conical filter screen 42 and through the pulp outlet 44 to form pulp products. The larger particles and pit particles move towards the center of the local vortex and move along the conical filter screen 42 towards the larger end of the pulping blade holder 43. Finally, the pulp, peel and pits are formed in the residue outlet 51 and discharged from the residue outlet 52.

[0037] It should also be noted that the connection relationships between the first drive motor 6, the second drive motor 7, and other components to be driven in this utility model are all conventional techniques used by those skilled in the art and are not described in detail in this utility model.
