[0002] Dough production is the primary step in pasta processing, and is usually produced using a dough making machine. The dough making machine squeezes and cuts the flour mixed with water into dough pieces of the same size. The dough pieces fall onto a conveyor belt and are sent to the next process by the conveyor belt.

[0003] An oil spray device is usually installed between the dough making machine and the conveyor belt. The oil spraying can prevent the dough pieces and the conveyor belt from sticking to each other. The oil spray devices currently used for dough making production on the market mostly use oil spray pumps and universal nozzles. The edible oil is pumped to the universal nozzle through the oil spray pump, and the universal nozzle sprays oil toward the dough pieces. There are some functional deficiencies in actual use, and there is room for improvement. For example, the current dough making machine oil spray nozzles are mostly set in front of the dough discharging port. The oil is sprayed at the moment the dough falls to the ground. Part of the oil mist will be blocked by the dough. The conveyor belt under the dough does not have sufficient oil, and powder sticking will still occur.

The nozzle 12 at the bottom of the secondary nozzle 23 simultaneously sprays an oil mist, forming an oil film on the surface of the dough to prevent it from drying out during transport. As the oil inside the cooking oil drum 3 is continuously pumped out, the weight of the drum 3 itself decreases. The weighing sensor 26 at the bottom of the drum support plate 25 monitors the weight of the drum 3 and feeds this data back to the controller 2. When the weight drops to a preset threshold, the speaker 27 automatically broadcasts a warning message, reminding staff to refill the drum promptly.
