Description

Technical Field

[0001] The present invention relates to the technical field of food processing equipment, and in particular to a puff premix powder raw material dispenser and a use method thereof. Background Art

[0002] During the puff manufacturing process, a layer of premix is ​​often sprinkled on the surface of the formed puff pastry. This process not only enhances the crispness of the baked puff crust but also improves its color, texture, and uniformity of expansion, resulting in a fuller, more three-dimensional finished product with a naturally cracked surface and an ideal golden color. Furthermore, the ingredients in the premix create a light, crispy layer during the high-temperature baking process, adding a layer of texture, preventing moisture loss, and extending the product's shelf life and flavor retention. This results in the puffs performing better in terms of appearance, taste, and commercial appeal.

[0003] However, when executing this process, existing spreaders often have uneven powder distribution, local over-thickness or omissions, and need to frequently stop to replenish powder, which not only increases manual intervention but also brings the risk of feed interruption. Moreover, the inability to recover the scattered premixed powder leads to a large amount of raw material waste. All these shortcomings seriously restrict the automation and standardization of puff production. Against the background of the growing development of high-efficiency and energy-saving industries, optimizing the energy-saving and work efficiency of spreaders is of great significance.

The puff premix powder raw material dispenser according to claim 2, characterized in that: A rotation speed regulator (700) is embedded in one side of the top block (501), and the rotation speed regulator (700) is electrically connected to the first drive motor (508). A top cover (701) is fixedly mounted on the top surface of the top block (501) via a hinge.

8. The puff premix powder raw material dispenser according to claim 2, characterized in that: Two adjustment grooves (800) are provided on one side of the top block (501), a gas spring (801) is fixedly installed inside the adjustment groove (800), a support frame (802) is provided inside the adjustment groove (800), the gas spring (801) and the support frame (802) are fixedly connected together, and a scrubbing brush (803) is fixedly installed on the bottom surface of the support frame (802).

9. The puff premix powder raw material dispensing machine according to claim 1, characterized in that: Two connecting holes (900) are respectively provided on the left and right sides of the top groove (200), bolts (901) are sleeved inside the connecting holes (900), and threaded grooves (902) are respectively provided on the left and right sides of the conveying frame (300).

10. A method for using a puff premix powder raw material sprinkler, based on the puff premix powder raw material sprinkler according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Pour the premixed powder into the storage tank (509) for storage, place the tray loaded with puff embryos on the crawler (601), close the top cover (701), and adjust the height of the scrub brush (803) by the gas spring (801) according to the height of the puff embryos to ensure that the scrub brush (803) maintains appropriate contact pressure with the surface of the puff embryos; Step 2: Start the electric push rod (510) to drive the inclined plate (513) and the premixed powder to rise, and at the same time start the second drive motor (517) to drive the cam (518) to rotate and vibrate the inclined plate (513), so as to push the powder material stably to the discharge trough (502), and then start the first drive motor (508) to drive the brush roller (507) to continuously rotate and clean the discharge screen (504), so that the premixed powder passes through the discharge screen (504) and falls evenly from the discharge hole (503); Step 3: Start the third drive motor (605) to drive the crawler belt (601) to operate, so that the puff embryos on the tray evenly receive the falling premixed powder. At the same time, the brush (803) gently sweeps along the surface of the puff embryos to remove excess powder. Step 4: When the premixed powder scattered on the crawler (601) moves along the crawler to the cleaning brush (607), the cleaning brush (607) sweeps the powder into the inclined hole (608), thereby realizing effective recovery of the scattered powder.
