[0041] Furthermore, the punching plate 3222 is also designed with pattern embossing, and patterns can be added to the surface of the biscuits while the pressing and cutting mold 322 is cutting the biscuits.

[0042] Preferably, the end of the piercing column 32221 is a pointed end or a conical structure. Preferably, the piercing column 32221 is a conical columnar structure.

[0043] By pressing and cutting the biscuits, the edges are sealed completely, and the biscuits have the characteristics of uniform expansion, smooth surface, uniform color, crisp taste, etc., which improves the appearance of the biscuits.

[0044] According to some embodiments of the present application, a pre-pressing device 340 may also be provided in the pressing and cutting module and the crust making module 100. The upper crust and the lower crust that are about to enter the pressing and cutting module are pre-laminated by the pre-pressing device 340, so that the upper crust and the lower crust are pre-laminated, so as to facilitate the pressing and cutting of the pressing and cutting module. Specifically, the pre-pressing device 340 includes a second roller 342, a second liftable bracket 341, and a third roller 343, wherein the third roller 343 is installed on the second bracket 341, and the third roller 343 is rotatably connected to the second bracket 341. The third roller 343 is driven by the second bracket 341 to move away from or close to the second roller 342 to adjust the gap between the third roller 343 and the second roller 342. The upper crust and the lower crust are respectively conveyed to the feed end of the pre-pressing device 340 by the upper crust conveying device 130 and the lower crust conveying device 140. The upper crust and the lower crust pass through the gap between the third roller 343 and the second roller 342 at the same time, and then enter the pressing module for cutting.

[0045] The pressed and cut biscuit sheets are sent to the baking module 400 for swelling, shaping, dehydration, coloring, etc. Specifically, by controlling the oven temperature and baking time, the biscuits can have a good crispy taste and attractive color after swelling, shaping, dehydration, and coloring.

[0046] The present application also provides a method for making sandwich biscuits using the above-mentioned device.

[0047] When kneading the dough, the mixing time is controlled to be 12 to 16 minutes, and the dough temperature is 33°C to 38°C; Both the upper crust and the lower crust are smooth dough sheets, and the thickness of the upper crust and the lower crust is about 0.6mm-1.5mm, ensuring the combination of crispy and crunchy taste of the product.

[0048] By applying seasoning fillings on the surface of the crust, the upper and lower layers of crust can be better combined into a whole that is not easy to separate, and the filamentous or loose fillings can be more stable and not easily scattered or lost, while increasing the mellow flavor and texture of the biscuits.

[0049] Filling making, using the filling making module 200 to make the filling and evenly spread the filling between the upper crust and the lower crust; specifically, frying in a filamentous or loose state, wherein the filamentous or loose finished product contains 2%-8% water, 10%-14% fat, and 20%-28% total sugar, which can improve the crispy taste of the filamentous or loose state. The filling making module 200 is used to make filamentous or loose fillings for sandwich biscuits. In addition, there is a difference in the rotation speed between the first feeding roller 221 and the second feeding roller 222 of the spreading device 220, specifically, the rotation speed of the second feeding roller 222 is greater than the rotation speed of the first feeding roller 221. The specific rotation speed can be set according to the actual situation. It can be understood that the amount of spreading can be increased by increasing the speed and increasing the height of the discharge port.

[0050] During the production of the biscuit bowl, the upper and lower crusts are wrapped with the fillings and enter the pressing and cutting module 300 for pressing and cutting, and a pattern is embossed on the surface of the biscuit bowl; specifically, the design of the pattern can be changed according to the needs.

[0051] Baking: sending the biscuit dough into the oven to complete swelling, shaping, dehydration and coloring in sequence; specifically, the oven temperature is set as follows: 150±20℃ for the upper part and 200±20℃ for the lower part during swelling; During molding: upper temperature 200±20℃, lower temperature 230±20℃; Dehydration: upper 180±20℃, lower 210±20℃; When coloring: upper 175±20℃, lower 180±20℃; The baking time can be set according to the driver's situation. After the biscuits are finished, the moisture content is about 0.8%-3.0%.

[0052] Oil spraying, spraying edible oil on the surface of the baked biscuits, controls the proportion of calories generated by fat in the total energy, and better ensures the healthy nutritional value of the biscuits.

[0053] Compared with other products that sprinkle filamentous or loose materials or other materials on the surface of the biscuits, the sandwich biscuits of the present application sandwich filamentous or loose materials or other materials in the middle of the biscuits as a sandwich, which can solve the problems of easy burning during baking and limited addition amount. Especially when producing filamentous or loose sandwich biscuits, compared with the current conveyor belt spreader and the spreading device 220 of the present application, the spreading device 220 of the present application can well solve the problem of uniform spreading of filamentous or loose materials such as filamentous or loose materials.
