Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a raw material puffing device with a loose structure. Background Technology

[0002] In the production process of wolfberry, lily bulb, lotus seed and white fungus soup, in order to shorten the soaking and cooking time and improve the taste and texture of the product, it is usually necessary to puff the raw materials of lotus seeds, lily bulbs and white fungus. In order to facilitate the puffing of raw materials of lotus seeds, lily bulbs and white fungus, workers usually use raw material puffing equipment. Existing raw material puffing equipment usually consists of a twin-screw puffer and a feeding box. For example, utility model patent application number CN202121529013.X discloses a twin-screw extruder, specifically including a frame, and a feeding device, an extrusion device, and a discharging device arranged sequentially from left to right on the frame; the feeding device includes a base, an extension tube, and an inlet groove, all of which are hollow structures. Several extension tubes are provided. The top of the base and the extension tubes are both fixedly provided with protrusions. The bottom of the extension tubes and the inlet grooves are both fixedly provided with sleeves that match the shape and contour of the protrusions. The sleeves are provided with locking attachments for locking them together with the protrusions. The extension tubes are located between the inlet grooves and the base, and the number of extension tubes between the inlet grooves and the bases is set according to the required height of the support. The sleeves of the bottom extension tubes are connected to the protrusions of the base. The protrusions of the extension tubes are connected to the sleeves of another extension tube or the sleeves of the inlet groove. The sleeves of the inlet grooves are connected to the protrusions of the top extension tubes. This utility model features an adjustable-volume feed hopper, offering the advantage of good practicality.

[0003] However, when puffing lotus seeds, lily bulbs, and white fungus, the raw materials are usually continuously fed into the twin-screw extruder through the feeding box. However, lily bulbs and lotus seeds are hard and irregularly shaped, and dried white fungus is fluffy and porous. During continuous feeding, they are prone to bridging and accumulation, which can lead to feeding interruptions and affect the puffing efficiency. At the same time, the density of lily bulbs, lotus seeds, and white fungus varies greatly. During continuous feeding, they are prone to stratification due to gravity, resulting in uneven material distribution within the screw. This leads to inconsistent taste of the puffed product and makes it inconvenient to use. Summary of the Invention

[0004] In view of this, the present invention provides a raw material puffing device with a loose structure, which has a sealing plate that can control the feed amount during the feeding process. During the rotation of the transmission shaft, the third transmission pulley will be driven to rotate. As the third transmission pulley rotates, the fourth transmission pulley will be driven to rotate through the transmission belt. As the fourth transmission pulley rotates, the control shaft will be driven to rotate. During the rotation of the control shaft, the eccentric pulley will be driven to rotate eccentrically. As the eccentric pulley rotates, the two swing frames will be pulled to swing simultaneously through the cooperation of the transmission belt and the control pulley. During the swing of the swing frames, the sealing plate will seal the discharge port of the second guide plate, so that the feed box can feed intermittently.

[0006] Furthermore, a control gear is coaxially fixedly connected to the left side of each of the two extrusion screws; both control gears are located inside the main body of the puffing device; the two control gears mesh with each other; a first drive motor is bolted to the rear left end face of the main body of the puffing device; the first drive motor is coaxially fixedly connected to the rear extrusion screw.

[0007] Furthermore, a second drive motor is bolted to the rear right end face of the second protective shell; the second drive motor is coaxially fixedly connected to the rear transmission shaft; a first transmission pulley is coaxially fixedly connected to the outside of the rear transmission shaft; a reversing shaft is rotatably connected inside the second protective shell; a second transmission pulley is coaxially fixedly connected to the outside of the reversing shaft; the second transmission pulley and the first transmission pulley are connected by a transmission belt.

[0008] Furthermore, an active reversing gear is coaxially fixedly connected to the external side of the reversing shaft; the active reversing gear is aligned with the second transmission pulley; the active reversing gear is located on the left side of the second transmission pulley; a driven reversing gear is coaxially fixedly connected to the external side of the front transmission shaft; the driven reversing gear meshes with the active reversing gear.

[0009] Furthermore, a loosening roller is coaxially fixedly connected to the outside of each of the two drive shafts; both loosening rollers are set inside the feed box; and multiple sets of beaters are fixedly connected to the outside of both loosening rollers in a ring array.

[0010] Furthermore, all of the aforementioned beaters are rectangular plate-shaped structures made of silicone; the beaters are arranged in an alternating pattern.

[0011] Furthermore, a third transmission pulley is coaxially and fixedly connected to the left side of each of the two transmission shafts; both third transmission pulleys are located inside the first protective housing; two control shafts are symmetrically and rotatably connected to the lower part of the feed box; a fourth transmission pulley is coaxially and fixedly connected to the left side of each of the two control shafts; both fourth transmission pulleys are located inside the first protective housing; and the two third transmission pulleys are respectively connected to the two fourth transmission pulleys via transmission belts.

[0015] Beneficial effects In the feeding process, the second drive motor is started, and then a series of transmissions cause the two transmission shafts to rotate in opposite directions. During the rotation of the transmission shafts, the loosening roller is driven to rotate. As the loosening roller rotates, it beats the lotus seeds, lily bulbs, and white fungus raw materials guided by the first guide plate, causing the agglomerates of the lotus seeds, lily bulbs, and white fungus raw materials to loosen, eliminating the risk of feeding blockage, realizing the preliminary premixing of multi-component raw materials, improving the uniformity of feeding, and effectively improving the practicality of the raw material puffing device.

[0016] During the rotation of the transmission shaft, the third transmission pulley rotates, which in turn drives the fourth transmission pulley via the transmission belt. The fourth transmission pulley then drives the control shaft, which in turn drives the eccentric pulley to rotate eccentrically. This rotation, in turn, pulls the two swing frames to swing simultaneously via the interaction of the transmission belt and the control pulley. During this swinging motion, the sealing plate seals the outlet of the second guide plate, allowing intermittent feeding from the feed hopper. This stabilizes the filling rate of the loose raw material and allows for precise, metered feeding, preventing excessive material intake and giving the screw sufficient time to push the material, thus preventing accumulation. Furthermore, during feeding pauses, the screw rotation carries away any hard particles (such as lotus seed fragments) remaining at the bottom of the feed hopper into the screw area, reducing the probability of blockage. This effectively improves the convenience of the raw material puffing device, making it more user-friendly. Attached Figure Description

[0037] The specific usage and function of this embodiment: In this invention, when puffing lotus seeds, lily bulbs, and white fungus, the lotus seeds, lily bulbs, and white fungus are injected into the puffing device body 1 through the feeding box 102. Then, the first drive motor 110 is started, causing the first drive motor 110 to drive the rear extrusion screw 106 to rotate. During the rotation of the rear extrusion screw 106, the rear control gear 109 will rotate. As the rear control gear 109 rotates, it will drive the front control gear 109, which meshes with it, to rotate. As the front control gear 109 rotates, it will drive the front extrusion screw 106 to rotate. With the rotation of the two extrusion screws 106, the lotus seeds, lily bulbs, and white fungus are extruded and conveyed. Then, the electric heating coil 108 is activated to... Lotus seeds, lily bulbs, and white fungus are heated during transport, subjecting them to high temperature and pressure. During this process, the moisture in the lotus seeds, lily bulbs, and white fungus is heated and vaporized, creating steam pressure. When the lotus seeds, lily bulbs, and white fungus are extruded from the extrusion die 107 into the discharge hopper 105, the pressure drops sharply, and the steam pressure inside the lotus seeds, lily bulbs, and white fungus is rapidly released, causing their volume to expand. During the puffing process, the raw materials are injected into the feeding box 102 through the feeding hopper 104. The raw materials entering the feeding box 102 are guided by the first guide plate 113. At this time, the second drive motor 118 is activated, causing it to drive the rear transmission. The rotating shaft 115 rotates, which in turn drives the first transmission pulley 117 to rotate. The rotation of the first transmission pulley 117, in turn, drives the second transmission pulley 119 to rotate via the transmission belt. The rotation of the second transmission pulley 119 drives the reversing shaft 116 to rotate. During the rotation of the reversing shaft 116, the driving reversing gear 120 rotates, which in turn drives the driven reversing gear 121 to rotate. The rotation of the driven reversing gear 121 then drives the front rotating shaft 115 to rotate, causing the two rotating shafts 115 to rotate in opposite directions. During the rotation of the rotating shafts 115, the loosening roller 122 rotates. As the loosening roller 122 rotates, it drives the loosening roller 122 to rotate as well. This rotation of the loosening roller 122 pats the lotus seeds, lilies, and white fungus raw materials guided by the first guide plate 113, loosening the agglomerates of these materials. Utilizing the properties of the silicone material in the patting paddle 123, the paddle gently breaks up the lotus seeds, lilies, and white fungus raw materials while preventing them from breaking. During the rotation of the transmission shaft 115, the third transmission pulley 124 rotates. The rotation of the third transmission pulley 124, in turn, drives the fourth transmission pulley 126 to rotate via a transmission belt. The rotation of the fourth transmission pulley 126, in turn, drives the control shaft 125 to rotate.During the rotation of the control shaft 125, the eccentric pulley 127 will rotate eccentrically. As the eccentric pulley 127 rotates, it will pull the two swing frames 128 to swing simultaneously through the cooperation of the transmission belt and the control pulley 129. During the swing of the swing frames 128, the sealing plate 130 will seal the outlet of the second guide plate 114, allowing the feed box 102 to feed intermittently.

[0039] The specific usage and function of this embodiment: In this invention, the elastic block 131 is designed so that when the two sealing plates 130 are closed, the elastic block 131 is pressed and generates a rebound force, which makes the contact surface fit more tightly, prevents dust from overflowing, and ensures the sealing effect between the two sealing plates 130.
