Description

Technical Field

[0001] The present invention relates to the field of food production, and in particular to a device and method for producing baked food. Background Art

[0002] While baked goods are designed to be free of foreign matter, finding them in them does occur. Research into foreign matter in foods has revealed that these include metal introduced from raw materials, coating loss from baking pans, and debris from friction. Careful screening of raw materials can prevent the incorporation of metal foreign matter, but this can significantly increase production costs. High-strength baking pans can reduce wear and coating loss due to deformation, but these are significantly heavier, placing greater demands on equipment and manpower during transport and transfer, increasing production costs. Finding a balance between production cost and product quality has become a pressing issue. Summary of the Invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a device and method for producing baked food with less foreign matter in the product.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a device for producing baked food, comprising:

[0005] The unloading device is used to unload the food dough onto the baking tray.

[0006] A conveying device, one end of which extends to the unloading device and is used to move the baking tray out of the unloading device;

[0007] The baking tray comprises an outer skin and a frame, the outer skin comprises a dish surface and side panels, the side panels surround the outer periphery of the dish surface and extend downward, and the side panels and the bottom of the dish surface form a groove cavity; the top of the dish surface is provided with a non-stick coating, and a separation area is provided between the outer edge of the non-stick coating and the outer edge of the dish surface; the frame is provided in the groove cavity, the frame comprises a ring frame, transverse ribs, longitudinal ribs, and a support plate, the ring frame is annular and is arranged along the side panels, there are two transverse ribs, both of which are arranged transversely in the ring frame, two support plates are provided between the two transverse ribs, both ends of the support plate extend to one side of the two transverse ribs respectively, and the other side of the two transverse ribs is provided with longitudinal ribs at the corresponding positions of the support plates, and the longitudinal ribs extend to the inner side of the ring frame; the thickness of the support plate is less than the thickness of the longitudinal ribs, and the width of the support plate is greater than the width of the longitudinal ribs; the side panels are provided with clamping areas at the positions corresponding to the longitudinal ribs;

[0008] A chuck device is provided between the conveyor device and the oven and is used to transfer the baking tray from the conveyor device to the oven. The chuck device includes two clamping arms, a receiving area for receiving the baking tray is provided between the two clamping arms, and two clamping protrusions are provided on the side of the two clamping arms facing the receiving area. When the clamping arms clamp the baking tray, the clamping protrusions press against the clamping area of ​​the baking tray.

[0009] An oven is used to bake food dough on a baking tray into finished food products.

[0010] The non-stick coating of the baking pan is applied only to the top of the pan and separated from the outer edge by a partition 5-10mm wide. The collision and friction during transportation of the baking pan will not impact the non-stick coating, greatly reducing the chance of the coating peeling off. Furthermore, the horizontal and vertical ribs, as well as the support plate of the baking pan's frame, effectively support the pan. In particular, the wider support plate positioned in the lower center of the pan provides ample support, preventing deformation. The clamping area on the sides of the baking pan's outer shell corresponds to the position of the vertical ribs. When clamping the pan, the force is concentrated on the highly compressive structures of the ribs, horizontal ribs, and support plate. This minimizes deformation of the pan and prevents the non-stick coating from cracking due to excessive deformation. During transportation and transfer of the baking pan, the non-stick coating is minimally affected by foreign matter, significantly reducing the risk of foreign matter in food.

[0011] Preferably, it also includes a magnetic rod device and a stirring barrel; the stirring barrel is arranged below the magnetic rod device, and is used to stir the flour and auxiliary materials screened by the magnetic rod device into noodle raw materials; the feeding device is used to make the noodle raw materials into food raw materials;

[0012] The magnetic rod device comprises a vertical channel and a plurality of magnetic rods. The plurality of magnetic rods are arranged in the vertical channel in a transverse direction and in parallel with each other. The plurality of magnetic rods are arranged alternately from top to bottom and front to back.

[0013] Multiple magnetic bars form a magnetic bar array. When flour and ingredients pass through the magnetic bar array, metal foreign matter in the flour and ingredients is more likely to be attracted by one of the magnetic bars. Moreover, the staggered and alternating magnetic bars can attract foreign matter over a wider range.

[0014] Preferably, the magnetic rod assembly further includes a toothed belt and a magnetic rod motor. A gear is provided at one end of the magnetic rod, the toothed belt meshes with the gears of all the magnetic rods, and the magnetic rod motor is connected to one of the gears to drive the gears to rotate. The movement of flour and ingredients within the magnetic rod array can easily cause blockages. The rotating magnetic rod can drive the flour and ingredients to move, reducing the risk of blockages.

[0015] Preferably, the lower ends of the side panels of the baking tray are folded inward, the bottom outer edges of the side panels are provided with insertion holes, the outer edges of the ring frame are provided with claws, the claws are inserted into the insertion holes, the four corners of the baking tray are arc-shaped, and the four corners of the baking tray are provided with welds covering the gaps between the ring frame and the side panels.

[0016] During transportation, the four corners of baking trays are most susceptible to collisions, leading to cracking and deformation. Deformed baking trays can easily get stuck on the conveyor line, causing production accidents. Rounding the corners and welding the frame to the side panels at these corners improves the structural strength of the baking trays and reduces deformation during collisions. Baking trays expand and contract as they move in and out of the oven. The outer shell and frame have different thicknesses. If the welds at the joints are small, they can easily fatigue and break after a period of use, releasing foreign matter. Using strip welds at these joints is costly, and the excessive number and density of welds can cause excessive deformation of the outer shell due to stress. Connecting the outer shell and frame with sockets and claws in locations less prone to collisions reduces costs and stress deformation of the outer shell.

[0017] A method for producing baked goods, comprising the following steps:

[0018] The flour and auxiliary materials pass through the magnetic rod device and enter the mixing barrel. The magnetic rod device includes a vertical channel and a plurality of magnetic rods. The plurality of magnetic rods are arranged horizontally and parallel to each other in the vertical channel. The plurality of magnetic rods are arranged alternately from top to bottom and front to back.

[0019] The mixing barrel mixes the flour and auxiliary materials into dough, divides the dough into food pieces and places them on the baking tray.

[0020] The baking tray includes an outer skin and a frame. The outer skin includes a dish surface and side panels. The side panels surround the outer periphery of the dish surface and extend downward, and the side panels and the bottom of the dish surface form a groove cavity. The top of the dish surface is provided with a non-stick coating, and a separation area is provided between the outer edge of the non-stick coating and the outer edge of the dish surface. The frame is arranged in the groove cavity. The frame includes a ring frame, transverse ribs, longitudinal ribs, and a support plate. The ring frame is annular and is arranged along the side panels. There are two transverse ribs, and the two transverse ribs are both arranged transversely in the ring frame. Two support plates are provided between the two transverse ribs. The two ends of the support plate extend to one side of the two transverse ribs respectively, and the other side of the two transverse ribs is provided with longitudinal ribs at the corresponding positions of the support plates, and the longitudinal ribs extend to the inner side of the ring frame. The thickness of the support plate is less than the thickness of the longitudinal ribs, and the width of the support plate is greater than the width of the longitudinal ribs. The side panels are provided with clamping areas at the positions corresponding to the longitudinal ribs.

[0021] The conveying device conveys the baking tray to the clamping device position. The two clamping arms of the clamping device clamp the clamping area of ​​the baking tray, clamp the baking tray and transfer it to the baking rack in the oven. The oven bakes the food dough on the baking tray to form bread.

[0022] By adopting the above-mentioned technical solution, the present invention has the following beneficial effects: the baking tray of the present invention does not deform, and the non-stick coating generates less foreign matter during transportation and transfer. This significantly reduces the generation of foreign matter in food. The magnetic array composed of multiple magnetic bars can effectively absorb metallic foreign matter in food ingredients without affecting the circulation of food ingredients. This reduces the generation of foreign matter during food production. BRIEF DESCRIPTION OF THE DRAWINGS
