Technical Field

[0001] This utility model relates to the technical field of puffing and extrusion devices, specifically a puffing and extrusion device for whole grain meal replacement powder. Background Technology

[0002] Five-grain meal replacement powder is a nutritious meal replacement food made from a variety of grains such as wheat, rice, corn, oats, and buckwheat, through processes such as proportioning, grinding, and puffing.

[0003] In the production process of whole grain meal replacement powder, an extrusion device is usually used. An extrusion device is a device that restructures and improves the physical properties of grain raw materials under high temperature and high pressure, enabling the grain raw materials to have good extrusion degree and palatability.

[0004] Most existing puffing and extrusion devices employ a single-screw puffer combined with a feeding hopper. During feeding, operators typically use a funnel-shaped feeding hopper to deliver the raw materials into the extrusion chamber of the puffer. However, this type of feeding hopper is prone to clogging due to the poor flowability of the raw powder, resulting in poor powder feeding. Therefore, this invention aims to provide a puffing and extrusion device for whole grain meal replacement powder that can easily solve the problem of feeding hopper clogging for users.

[0007] Optionally, a spring is provided inside the moving cavity, with the two ends of the spring elastically abutting against the bottom wall of the feed cylinder and the bottom surface of the limiting member, respectively.

[0008] Optionally, the spring is sleeved on the feed rod.

[0009] Optionally, the mounting assembly includes at least two mounting plates; the two mounting plates are respectively fixed to the outer peripheral wall of the feed cylinder, and the top of the feeding hopper is provided with limiting grooves suitable for accommodating the free ends of the mounting plates.

[0016] (III) Beneficial Effects Compared with the prior art, this utility model provides a puffing and extrusion device for whole grain meal replacement powder, which has the following beneficial effects: 1. This utility model, by incorporating a material guide rod, addresses the issue of powder blockage in the feeding hopper due to poor flowability. First, the operator holds the top of the guide rod and pushes it up and down repeatedly within the moving chamber. Simultaneously, the bottom of the guide rod moves up and down at the discharge port, pressing and dislodging the powder blockage near the discharge port, thus restoring its flowability. After unblocking, the powder smoothly enters the extrusion chamber of the extruder from the feeding hopper, where it undergoes extrusion under high temperature and pressure. 2. This utility model is equipped with a motor, a first pulley, a second pulley, and a transmission belt. When it is necessary to clear the powder in the feeding hopper, the motor is started, and the output end of the motor drives the first pulley to rotate. The first pulley transmits power to the second pulley through the transmission belt. The second pulley drives the feeding rod to rotate around its own axis, so that the bottom end of the feeding rod rotates and stirs the blocked material. 3. This utility model uses feed blades that are radially and evenly distributed on the circumference of the bottom end of the feed rod, forming a structure similar to a stirring paddle. When the feed rod rotates under the drive of the motor, several feed blades rotate synchronously with the feed rod at high speed, continuously cutting, shearing and crushing the powder blocked at the feed inlet, completely destroying the bridging structure and agglomeration of the powder.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figures 1 to 5According to an embodiment of the present invention, a technical solution is provided: a puffing and extrusion device for a multigrain meal replacement powder, comprising an extruder 1 for puffing and extruding the powder, a feeding hopper 2 installed at the inlet of the extruder 1, and a feeding mechanism for loosening the feeding hopper 2; the feeding hopper 2 has a feeding port 3 and a discharging port 4; the feeding mechanism includes a feeding rod 18, a feeding cylinder 19, and an installation assembly; the installation assembly is used to selectively fix the feeding cylinder 19 at the feeding port 3; a movable cavity 5 is defined inside the feeding cylinder 19, the feeding rod 18 movably passes through the feeding cylinder 19, a limiting member 6 is fixedly sleeved on the feeding rod 18, the limiting member 6 is slidably disposed in the movable cavity 5, the limiting member 6 is used to restrict the middle part of the feeding rod 18 from leaving the movable cavity 5, and the bottom end of the feeding rod 18 is located at the discharging port 4.

[0021] In the multigrain meal replacement powder puffing and extrusion device with the above-described structure, when the powder in the feeding hopper 2 becomes clogged due to poor flowability, the operator first holds the top of the feeding rod 18 and pushes and pulls the feeding rod 18 up and down repeatedly in the moving chamber 5. During this process, the bottom end of the feeding rod 18 moves up and down synchronously at the discharge port 4, pressing and dislodging the powder that is clogged near the discharge port 4, thus loosening the lumps or bridging powder and restoring its flowability. After unblocking, the powder smoothly enters the extrusion chamber (not shown in the figure) of the puffer 1 from the discharge port 4 of the feeding hopper 2, where it undergoes puffing and extrusion processing under high temperature and high pressure.

[0022] In this embodiment, a spring 7 is provided in the moving cavity 5. The two ends of the spring 7 elastically abut against the bottom wall of the feeding cylinder 19 and the bottom surface of the limiting member 6, respectively. With this arrangement, the spring 7 will be in a compressed state, constantly pushing the limiting member 6 and the feeding rod 18 upward, so that the feeding rod 18 will automatically return to the lifting state when it is not subjected to external force.

[0023] Specifically, when the operator presses down on the material feeding rod 18 to perform the material feeding operation, the spring 7 is further compressed and stores energy. The bottom end of the material feeding rod 18 pushes down to loosen the blocked material. After releasing the hand, the spring 7 immediately releases its elastic force and bounces the material feeding rod 18 back to its initial position, achieving automatic reset. The operator only needs to press repeatedly to complete the continuous material feeding action without manually lifting the material feeding rod 18, which reduces labor intensity and improves material feeding efficiency.

[0024] In this embodiment, the spring 7 is sleeved on the feed rod 18; this arrangement allows the feed rod 18 to guide and limit the spring 7, preventing the spring 7 from shifting laterally, twisting, deforming, or dislodging during repeated compression and extension, and keeping the spring 7 in the correct working position at all times.

[0025] In this embodiment, the installation assembly includes at least two mounting plates 8; the two mounting plates 8 are respectively fixed to the outer peripheral wall of the feed cylinder 19, and the top of the feeding bin 2 is provided with limiting grooves 9 suitable for accommodating the free ends of the mounting plates 8; with this configuration, during installation, the operator only needs to align the free ends of the mounting plates 8 with the limiting grooves 9 and insert them downwards, and the mounting plates 8 can be embedded in the limiting grooves 9 to achieve quick connection and positioning between the feed cylinder 19 and the feeding bin 2.

[0026] Specifically, at least two mounting plates 8 are circumferentially distributed, and the multi-point support makes the feeding cylinder 19 more firmly and stably fixed at the feeding port 3, preventing the feeding cylinder 19 from shaking or falling off when the feeding rod 18 moves up and down, thus ensuring the safety and reliability of the feeding operation.

[0027] In this embodiment, the mounting plate 8 has an L-shaped structure, and its free end is detachably fixed to the feeding bin 2 by a locking member. With this configuration, during installation, the operator first inserts the mounting plate 8 into the limiting groove 9, and then locks the free end of the mounting plate 8 onto the feeding bin 2 using the locking member, achieving dual positioning and locking, resulting in a more secure and reliable connection.

[0028] In this embodiment, the locking component is a screw 10; the screw 10 moves through the free end of the mounting plate 8 and is threadedly connected to the feeding bin 2; with this configuration, during installation, after the operator positions the mounting plate 8 in place, they can rotate the screw 10 by hand or with a screwdriver to screw it into the free end of the mounting plate 8 and into the feeding bin 2.

[0029] In this embodiment, a hand-tightening disc 11 is fixed to the end of the screw 10; this arrangement makes it convenient for the user to turn the screw 10.

[0030] In this embodiment, a number of friction-enhancing parts 12 are arranged at intervals along the circumference of the top of the feed rod 18; this arrangement makes it easier for the user to hold the feed rod 18.

[0031] In this embodiment, a motor 13 is mounted on the mounting plate 8. A pulley 14 is fixedly fitted onto the output end of the motor 13, and a pulley 15 is fixedly fitted onto the feed rod 18. A transmission belt 16 is fitted between pulley 14 and pulley 15. When it is necessary to clear the powder from the feed hopper 2, the motor 13 is first started, causing the output end of the motor 13 to drive pulley 14 to rotate. Pulley 14 transmits power to pulley 15 through the transmission belt 16. Pulley 15 drives the feed rod 18 to rotate around its own axis, causing the bottom end of the feed rod 18 to rotate and stir the blocked material. It can be understood that the rotational motion can effectively break up the powder bridging and agglomeration structure, significantly shortening the feeding time.

[0032] In this embodiment, a number of feed blades 17 are installed at intervals along the circumference of the bottom end of the feed rod 18. With this arrangement, the feed blades 17 are radially and evenly distributed on the circumference of the bottom end of the feed rod 18, forming a structure similar to a stirring paddle. When the feed rod 18 is driven by the motor 13 to rotate, the number of feed blades 17 rotate synchronously with the feed rod 18 at high speed, continuously cutting, shearing and crushing the powder blocked at the discharge port 4, completely destroying the bridging structure and agglomeration of the powder.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
