Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food processing equipment, in particular to a micro liquid filling structure for a food extruder. Background Art
[0002] A food extruder is an efficient and continuous food processing equipment that extrudes food raw materials into a formed shape by mechanical force and is widely used in the production of various foods such as noodles, biscuits, and puffed foods.
[0003] During the working process of the food extruder, the raw materials are sent into the extruder after pretreatment and are extruded into the required shape under high temperature and high pressure through the rotation and propulsion of a screw or a plunger. In order to improve the taste, color, nutritional value of the product or meet specific process requirements, it is often necessary to add a small amount of liquid raw materials, such as water, flavoring liquid, etc., to the main material. The precise addition of these trace liquids is crucial for ensuring product quality.
[0004] However, there are at least the following defects in the above-mentioned prior art: Due to the high-pressure environment inside the food extruder, and the extremely small amount of liquid to be added and the need for precise control, the existing structures are difficult to achieve. Summary of the Utility Model
[0005] By providing a micro liquid filling structure for a food extruder in the embodiments of the present application, the technical problem in the prior art of difficult addition of a small amount of liquid into the food extruder is solved.
[0006] To solve the above technical problem, the utility model adopts the following technical solution. A micro liquid filling structure for a food extruder includes a support sleeve. One end of the support sleeve is provided with a material guiding disk. A liquid filling pipe is arranged at one end of the material guiding disk facing the support sleeve. The front end of the liquid filling pipe extends towards the inside of the support sleeve. The inside of the liquid filling pipe has a liquid flow channel A. The front end of the liquid flow channel A is communicated with the inside of the support sleeve through a through hole. The rear end of the liquid flow channel A extends to the material guiding disk. A liquid flow channel B is arranged in the material guiding disk. One end of the liquid flow channel B is communicated with the rear end of the liquid flow channel A. The other end of the liquid flow channel B extends along the radial direction of the material guiding disk and can be installed with a liquid injection pipe. The input end of the liquid injection pipe is located outside the support sleeve.
[0007] Since the inside of the liquid filling pipe has a liquid flow channel A, the front end of the liquid flow channel A is communicated with the inside of the support sleeve through a through hole, the rear end of the liquid flow channel A is communicated with the liquid flow channel B in the material guiding disk, and a liquid injection pipe can be installed at the port of the liquid flow channel B. Therefore, a small amount of liquid can be injected into the support sleeve through the liquid injection pipe to be mixed with the material, realizing precise control of liquid addition.
[0008] Furthermore, one end of the liquid flow channel B near the edge of the guide tray has internal threads. Correspondingly, the front end of the liquid injection pipe has external threads, and the external threads can be engaged with the internal threads; thus, a better sealing effect can be provided to prevent liquid from leaking from the connection during the liquid injection process, ensuring the accuracy and stability of the micro-liquid injection.
[0009] Furthermore, the guide tray is provided with a plurality of shunt holes, which penetrate through both axial ends of the guide tray and are arranged around the central position in the radial direction of the guide tray.
[0010] Furthermore, the rear end of the liquid injection pipe is fixed to the middle part in the radial direction of the guide tray.
[0011] Furthermore, the length of the liquid injection pipe is not less than twice the thickness of the guide tray, and the radial dimension of the front end of the liquid injection pipe is smaller than that of the rear end; thus, during the liquid injection process, it is beneficial for the liquid to be more evenly mixed with the material, thereby improving the product quality.
[0012] Furthermore, the diameter of the through hole at the front end of the liquid injection pipe is smaller than the diameter of the liquid flow channel A; thus, during the liquid injection process, it can effectively prevent liquid backflow and reduce the risk of blockage.
[0013] It can be seen from the above technical solutions that the present utility model has at least the following technical effects or advantages:
[0014] Since the liquid injection pipe has a liquid flow channel A inside, the front end of the liquid flow channel A is connected to the inside of the support sleeve through a through hole, the rear end of the liquid flow channel A is connected to the liquid flow channel B inside the guide tray, and a liquid injection pipe can be installed at the port of the liquid flow channel B. Therefore, micro-liquid can be injected into the support sleeve through the liquid injection pipe to be mixed with the material, realizing precise control of liquid addition.

[0019] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.
[0020] The present utility model discloses a micro liquid filling structure for a food extruder, which includes a support sleeve 1. One end of the support sleeve 1 is installed with a material guiding plate 2. The material guiding plate 2 is provided with diversion holes 3. During the food extrusion process, the food enters the support sleeve 1 through the diversion holes 3 on the material guiding plate 2. In one example, a liquid filling tube 7 is arranged at one end of the material guiding plate 2 facing the support sleeve 1. A liquid injection tube 6 can be installed on one side of the material guiding plate 2 outside the support sleeve 1. Channels for the liquid to flow through are provided in both the liquid filling tube 7 and the material guiding plate 2. The micro liquid can be injected into the support sleeve 1 through the liquid injection tube 6.
[0021] As Figure 1 shown, the material guiding plate 2 is provided with a plurality of diversion holes 3. The diversion holes 3 penetrate through both axial ends of the material guiding plate 2 and are arranged around the central position in the radial direction of the material guiding plate 2. Thus, during the food extrusion process, the food can be more evenly extruded into the support sleeve 1. The rear end of the liquid filling tube 7 is fixed to the middle of the material guiding plate 2, and the front end of the liquid filling tube 7 extends towards the inside of the support sleeve 1. During the liquid filling process, the liquid to be filled is injected from the rear end to the front end of the liquid filling tube 7 and finally enters the support sleeve 1 to be mixed with the food.
[0022] Specifically in this embodiment, the inside of the liquid filling tube 7 has a liquid flow channel A4. The front end of the liquid flow channel A4 is communicated with the inside of the support sleeve 1 through a through hole. The rear end of the liquid flow channel A4 extends to the material guiding plate 2. A liquid flow channel B5 is provided in the material guiding plate 2. The liquid flow channel B5 extends along the radial direction of the material guiding plate 2, so that one end of the liquid flow channel B5 is communicated with the rear end of the liquid flow channel A4, and the other end of the liquid flow channel B5 extends to the outer periphery of the material guiding plate 2. More specifically, the end of the liquid flow channel B5 close to the edge of the material guiding plate 2 has an internal thread. Correspondingly, the front end of the liquid injection tube 6 has an external thread. The external thread at the front end of the liquid injection tube 6 can cooperate with the internal thread of the liquid flow channel B5. This can provide a better sealing effect, prevent the liquid from leaking from the connection during the filling process, and ensure the accuracy and stability of the micro liquid filling.
[0023] In this embodiment, the length of the liquid filling pipe 7 is not less than twice the thickness of the material guiding plate 2, and the radial dimension of the front end of the liquid filling pipe 7 is larger than that of the rear end. Thus, during the liquid injection process, it is beneficial for the liquid to be more evenly mixed with the material, thereby improving the product quality. In addition, the diameter of the through hole at the front end of the liquid filling pipe 7 is much smaller than the diameter of the liquid flow channel A4. Thus, during the liquid injection process, liquid backflow can be effectively prevented, and at the same time, the risk of blockage is reduced.
