Description

Technical Field

[0001] The invention belongs to the technical field of food production, and in particular relates to extrusion molding equipment for food production. Background Art

[0002] Extrusion equipment plays a vital role in the food industry, utilizing extrusion technology to process food materials into products with specific shapes and textures. Food extrusion involves pre-processing food materials (such as crushing, moisture conditioning, and mixing) before placing them in an extruder. The extruder then mechanically forces them through a specially designed die to form a product with a desired shape and texture.

[0003] Currently, most existing extrusion equipment can only extrude specific food ingredients into specific shapes. The resulting food's shape and firmness are essentially the same, and there's no way to adjust the firmness of the extruded food while maintaining the same shape. This imposes certain limitations on food processing, making it impossible to achieve a diverse taste without compromising on shape. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide an extrusion molding device for food production, aiming to solve the problems raised in the above background technology.

[0005] The embodiment of the present invention is implemented as follows: an extrusion molding device for food production includes a workbench and further includes:

[0006] A pre-processing module is installed on the workbench and is used to pre-extrude the food raw materials to be processed and make the extruded food raw materials into strips with a certain thickness;

[0007] A molding processing module, the molding processing module includes a second drive motor mounted on a workbench, the output end of the second drive motor is connected to a drive shaft, two connecting frames are symmetrically provided on the drive shaft, a plurality of molding dies are arranged in a ring between the two connecting frames, each molding die has a plurality of molding cavities equidistantly distributed along the axial direction of the drive shaft, and an adjustable pressure plate is slidably installed in each molding cavity along the radial direction of the drive shaft;

[0008] A control module, which includes a plurality of adjustment slides installed in a ring on the drive shaft, and the number of the adjustment slides is the same as the number of forming molds. The adjustment slide is installed on the drive shaft along the axial direction of the drive shaft. The end of the adjustment slide close to the second drive motor is connected to the drive shaft through a plurality of return springs. A plurality of adjustment links are equidistantly installed on the adjustment slide, and the number of adjustment links on one adjustment slide is the same as the number of forming cavities in a forming mold. One end of the adjustment link is hinged on the adjustment slide, and the other end of the adjustment link is hinged on the adjustable pressure plate. The control module also includes an adjustment unit arranged at the end of the drive shaft away from the second drive motor, and the adjustment unit is used to push the adjustment slide located at the bottom to perform a reciprocating motion along the axial direction of the drive shaft.

[0009] A further technical solution is that the pre-processing module includes a mounting frame installed on the workbench, a mounting plate is slidably installed on the mounting frame in the vertical direction, and a first telescopic member is also provided on the top of the mounting frame for driving the mounting plate to slide up and down, a pressure roller is rotatably installed on the bottom of the mounting plate, a first drive motor is also installed on the mounting plate, and the output end of the first drive motor is connected to the pressure roller through a transmission member.

During use, the food material to be processed is first extruded into a strip of a specified thickness through a pre-processing module. The pre-extruded food material is then transported to the molding module for extrusion molding. To perform food extrusion molding, the second drive motor is activated. The second drive motor rotates the drive shaft, which, via a connecting frame, drives the molding dies to rotate synchronously. As the molding dies rotate, the molding dies located directly below squeeze the food material, forming it into the cross-sectional shape of the molding cavity. Simultaneously, an adjustment unit pushes the lowest adjustment slide to slide axially along the drive shaft. A return spring provided on the adjustment slide drives the lower adjustable pressure plates to slide synchronously within the corresponding molding cavity, thereby squeezing the food material within the molding cavity.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] like Figure 1-Figure 5 As shown, an extrusion molding device for food production provided by one embodiment of the present invention includes a workbench 1 and further includes:

[0026] A pre-processing module 2 is installed on the workbench 1 and is used to pre-extrude the food material to be processed and make the extruded food material into strips of a certain thickness;

[0027] The molding processing module 3 includes a second drive motor 31 mounted on the workbench 1. The output end of the second drive motor 31 is connected to a drive shaft 32. Two connecting frames 33 are symmetrically provided on the drive shaft 32. A plurality of molding dies 34 are arranged in a circle between the two connecting frames 33. Each molding die 34 has a plurality of molding cavities 341 equidistantly distributed along the axial direction of the drive shaft 32. An adjustable pressure plate 35 is slidably installed in each molding cavity 341 along the radial direction of the drive shaft 32.

[0028] The control module 4 includes a plurality of adjustment slides 41 mounted in a ring on the drive shaft 32, and the number of the adjustment slides 41 is the same as the number of the forming molds 34. The adjustment slide 41 is slidably mounted on the drive shaft 32 along the axial direction of the drive shaft 32. The end of the adjustment slide 41 close to the second drive motor 31 is connected to the drive shaft 32 through a plurality of return springs 43. A plurality of adjustment links 42 are equidistantly mounted on the adjustment slide 41, and the number of adjustment links 42 on one of the adjustment slides 41 is the same as the number of forming cavities 341 in a forming mold 34. One end of the adjustment link 42 is hinged on the adjustment slide 41, and the other end of the adjustment link 42 is hinged on the adjustable pressure plate 35. The control module 4 also includes an adjustment unit arranged at the end of the drive shaft 32 away from the second drive motor 31, and the adjustment unit is used to push the adjustment slide 41 located at the bottom to perform a reciprocating motion along the axial direction of the drive shaft 32.

[0029] In this embodiment of the present invention, during use, the food material to be processed is first extruded into a strip of a specified thickness through the pre-processing module 2, and the pre-extruded food material is then transported to the forming module 3 for extrusion molding. When the food extrusion molding is to be performed, it is only necessary to start the second drive motor 31. The second drive motor 31 can drive the drive shaft 32 to rotate. The drive shaft 32 can drive the various forming molds 34 to rotate synchronously through the connecting frame 33. As the various forming molds 34 rotate, the forming mold 34 located directly below will squeeze the food material, so that the food material is pressed into the cross-sectional shape of the forming cavity 341. At the same time, the adjusting unit will push the adjusting slide 41 at the bottom to slide along the axial direction of the driving shaft 32. The adjusting slide 41 can drive the adjustable pressure plates 35 located directly below to slide synchronously in the corresponding forming cavity 341 through the return spring 43 arranged thereon, thereby squeezing the food raw materials in the forming cavity 341. The single displacement of the adjusting slide 41 can also be adjusted by the adjusting unit, and then the compression amount of the adjustable pressure plate 35 can be adjusted, so that the food raw materials in the forming cavity 341 can be squeezed to different degrees, so that the processed food can obtain different firmness.

[0030] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the pre-processing module 2 includes a mounting frame 21 installed on the workbench 1, and a mounting plate 22 is slidably installed on the mounting frame 21 in the vertical direction, and a first telescopic member 23 for driving the mounting plate 22 to slide up and down is also provided on the top of the mounting frame 21, and a pressure roller 24 is rotatably installed on the bottom of the mounting plate 22, and a first drive motor 25 is also installed on the mounting plate 22, and the output end of the first drive motor 25 is connected to the pressure roller 24 through a transmission member.

[0031] In an embodiment of the present invention, the first telescopic member 23 may be an electric telescopic rod or a telescopic cylinder, and the transmission member may be a pulley-belt mechanism. During use, the first telescopic member 23 is simply controlled to extend and retract, thereby driving the mounting plate 22 to move up and down along the chute provided on the mounting frame 21. This, in turn, drives the pressing roller 24 to move up and down synchronously via the mounting plate 22, thereby adjusting the distance between the bottom end of the mounting plate 22 and the upper surface of the workbench 1. The first drive motor 25 is then activated, which drives the pressing roller 24 to rotate synchronously via the pulley-belt mechanism, thereby extruding the food material to be processed into a strip of a specified thickness. The pre-extruded food material is then transported to the forming module 3 for extrusion.

[0032] like Figure 6 As shown, as a preferred embodiment of the present invention, the pre-processing module 2 also includes a scraper 26 installed on the mounting plate 22, and the mounting plate 22 is arranged on the incoming material side of the pressure roller 24 (i.e., the side where the raw materials are put in) and abuts against the side wall of the pressure roller 24.

[0033] In an embodiment of the present invention, the scraper 26 can scrape off the food raw materials attached to the pressing roller 24. The scraped raw materials will fall to the bottom and be squeezed again together with other food raw materials through the pressing roller 24 and transported to the forming processing module 3, thereby effectively preventing excessive food raw materials from remaining on the pressing roller 24 and affecting the subsequent processing quality.

[0034] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the adjustment unit includes a limiting triangle block 44 installed on the inner wall of the adjustment slide 41, and a second telescopic member 46 arranged on the workbench 1, the second telescopic member 46 can be linearly telescopic along the axial direction of the drive shaft 32, and the telescopic end of the second telescopic member 46 is connected to the adjustment lever 45.

[0035] In an embodiment of the present invention, the second telescopic member 46 is an electrically operated telescopic rod. During use, as the drive shaft 32 rotates, the adjustment slides 41 rotate synchronously. When an adjustment slide 41 reaches its lowest position, the limiting triangle block 44 provided at its end contacts the adjustment lever 45. The adjustment lever 45 limits the inclined surface of the limiting triangle block 44. As the drive shaft 32 rotates, the adjustment slide 41 slides axially along the drive shaft 32. The adjustment slide 41, via a return spring 43 provided thereon, drives the adjustable pressure plates 35 located directly below it to slide synchronously within the forming cavity 341, thereby squeezing the food material in the forming cavity 341. By controlling the extension and retraction of the second telescopic member 46, the contact position of the adjusting lever 45 and the limiting triangle block 44 can be controlled, thereby adjusting the single displacement of the adjustment slide 41 and, in turn, the compression of the adjustable pressure plates 35. This allows the food material in the forming cavity 341 to be squeezed to varying degrees, resulting in different degrees of firmness of the processed food.

[0036] When the limiting triangle block 44 rotates to disengage from the adjusting lever 45, the elastic restoring force of the reset spring 43 will restore the adjusting slide 41 to its initial position, thereby causing the adjustable pressure plate 35 to simultaneously restore to its initial position and wait for the next processing.

[0037] Working Principle: During use, the first telescopic member 23 is first controlled to extend and retract, thereby driving the mounting plate 22 to move up and down along the slide groove provided on the mounting frame 21. This, in turn, drives the pressing roller 24 to move up and down synchronously through the mounting plate 22, thereby adjusting the distance between the bottom end of the mounting plate 22 and the upper surface of the workbench 1. The first drive motor 25 is then activated. The first drive motor 25 drives the pressing roller 24 to rotate synchronously via a pulley and belt mechanism, thereby extruding the food material to be processed into a strip of a specified thickness and conveying the pre-extruded food material to the forming processing module 3 for extrusion molding. The second drive motor 31 is then activated, which drives the drive shaft 32 to rotate. The drive shaft 32 drives the various forming molds 34 to rotate synchronously via the connecting frame 33. As each forming mold 34 rotates, the forming mold 34 located directly below squeezes the food material, causing it to be pressed into the cross-sectional shape of the forming cavity 341. At the same time, as the drive shaft 32 rotates, each adjusting slide 41 will rotate synchronously. When an adjusting slide 41 rotates to the lowest position, the limiting triangle block 44 provided at its end will abut against the adjusting stop rod 45. Through the limiting effect of the adjusting stop rod 45 on the inclined surface of the limiting triangle block 44, as the drive shaft 32 rotates, the adjusting slide 41 will slide along the axial direction of the drive shaft 32. The adjusting slide 41 can drive the respective adjustable pressure plates 35 located directly below to slide synchronously in the forming cavity 341 through the return spring 43 provided thereon, thereby squeezing the food raw materials in the forming cavity 341. By controlling the extension and retraction of the second telescopic member 46, the contact position of the adjusting stop rod 45 and the limiting triangle block 44 can be controlled, thereby adjusting the single displacement of the adjusting slide 41, and then adjusting the compression amount of the adjustable pressure plate 35, so that the food raw materials in the forming cavity 341 can be squeezed to different degrees, so that the processed food obtains different firmness.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
