| Barbecue products and baked pasta products play an important role in the daily lives of residents in Xinjiang,and the market demand is large.However,the functions of machines on the market are relatively single,and there are no machines that can both cook meat products and bake pasta.In addition,the baking method is based on charcoal fire.During the baking process,harmful gases such as smoke,CO,CO2,and SO2 are generated.The working environment is very poor,the degree of mechanization and utilization of heat energy are low,and the operator's labor intensity is high.In order to solve these problems,this article designs and develops a baking method that is similar to the traditional roast whole lamb and roast roast,and uses gas as a heat source to rotate the roasting device.The device is mainly composed of a combustion system,a drum,a transmission system,an electrical control system,a collection tray mechanism,and an auxiliary tool.The combustion system consists of two infrared gas burners,which are placed on both sides of the furnace in an inclined manner so that the internal temperature of the furnace is evenly distributed.The transmission system has realized the mechanization of the barbecue and reduced the labor intensity of the workers.The electrical control system can automatically control the temperature inside the furnace and automatically alarm when the burner intake is insufficient or the ignitor operates abnormally.The oil collecting pan mechanism is composed of a collecting pan and a water circulation system.The oil collecting pan is placed on the burner pad and can collect the oil dripping during the baking of meat products.The water circulation system can reduce the evaporation of the water in the oil pan.Ancillary tools can reduce the risk of workers getting burned in hot working conditions and increase the utility of the device.Simulation software was used to simulate the improved structure and analyze the feasibility of the improved scheme.The FLUENT software is used to simulate the internal temperature field and air flow field of the barbecue device.The simulation results show that the improved internal temperature distribution of the barbecue machine is more uniform and the air flow is more smooth.The ANSYS Workbench was used to simulate the internal flow field in the grill body of the improved drum.The results show that the improvement of the drum cannot achieve the expected goal of improving the air convection inside the furnace.An orthogonal test was conducted on the barbecue test and roasting test.The results of the analysis showed that 1.5 times of the intake valve of the burner was vented,the discharge area of the vent hole was 282.6 cm2,and the motor was rotated at a rate of 15 r/min.The quality of the barbecue is the best.The heat utilization rate of the device under the best process is about 12.1%.The best technological process for roasting broilers is baking at 220-230°C for 11 min.Subsequently,a continuous baking test was conducted and the average baking time of the roast roast,the average diameter of the roast,and the efficiency of roasting roast per hour were measured. |
