DETAILED DESCRIPTION

[0024] See also Figure 1-4 , further illustrate the embodiments of the present utility model;

[0025] like Figure 1 As shown, an oil spraying device for producing cookies comprises a bracket 1, an oil pump 6 is fixed on the top of the bracket 1, an oil inlet pipe 7 is fixed to the oil inlet end of the oil pump 6, an oil outlet pipe 9 is fixed to the oil outlet end, the lower end of the oil outlet pipe 9 passes through the top of the bracket 1 and is fixed with an oil spraying assembly in communication therewith, a conveyor belt 3 is provided at the bottom of the bracket 1, baffles 2 are installed above the front and rear sides of the bracket 1, the baffles 2 are higher than the conveyor belt 3, an oil tank 4 is provided on one side of the bracket 1, a cannula 5 is inserted into the oil tank 4, and a hose 8 is connected between the cannula 5 and the oil inlet pipe 7; the conveyor belt 3 is used to convey the cookies. Cookies, the oil tank 4 is filled with palm oil, and the two baffles 2 are set to prevent a large amount of oil mist from diffusing into the working environment when the device sprays oil; when it is necessary to spray oil on the cookies on the conveyor belt 3, first close the conveyor belt 3, and then start the oil pump 6 to pump the oil in the oil tank 4 into the cannula 5, the hose 8, and the oil inlet pipe 7 in turn and then enter the oil pump 6, and then the oil is transported to the oil spray assembly through the oil outlet pipe 9. The oil spray assembly atomizes the oil into oil mist and sprays it on the cookies. Finally, close the oil pump 6 and start the conveyor belt 3 to transport the cookies after the oil spraying.

[0026] like Figure 1 and 2 As shown, the oil spray assembly includes an oil drain pipe 11 installed at the lower end of the oil outlet pipe 9 and several nozzles 12 installed on the lower side of the oil outlet pipe 9. The lower ends of the several nozzles 12 are detachably connected (such as embedded or clamped) with filters; the setting of the filter can prevent external particles from entering the nozzle 12, ensuring that the inside of the nozzle 12 remains clean for a long time to comply with food health and safety regulations; the filter needs to be inspected and cleaned regularly to ensure that the nozzle 12 sprays oil normally; after the oil pump 6 is started, the oil in the oil outlet pipe 9 will enter the oil drain pipe 11, and then flow into each nozzle 12 under the action of pressure. The nozzle 12 is a spray nozzle, and the nozzle 12 atomizes the oil into oil mist and then sprays it on the cookies through the filter.

[0027] Furthermore, the filter element includes several filter screen covers 18 and several connecting rods 19. The filter screen covers 18 are provided with several and are detachably connected (such as embedded or clamped) to the lower end of the nozzle 12. Each connecting rod 19 is fixed between two adjacent filter screen covers 18. The multiple filter screen covers 18 are connected together by multiple connecting rods 19, which makes it convenient for the staff to quickly install the multiple filter screen covers 18 one by one at the lower ends of multiple nozzles 12; when disassembling, the multiple filter screen covers 18 can be collectively removed from the lower ends of multiple nozzles 12 by pulling several connecting rods 19. This design improves the installation efficiency and disassembly efficiency of the filter element.

[0028] A negative pressure suction assembly is installed on the oil inlet pipe 7, which includes a negative pressure pump 14, a mounting pipe 15, a mounting pipe 2 16 and a connecting pipe 13. The mounting pipe 15 and the mounting pipe 2 16 are both fixed on the oil inlet pipe 7 and communicate with it. The liquid inlet end of the negative pressure pump 14 is communicated with the mounting pipe 15, and the liquid outlet end is installed with an oil-gas separator 21, which is communicated with the mounting pipe 2 16. The connecting pipe 13 is installed on the oil inlet pipe 7, and the lower end of the connecting pipe 13 passes through the top of the bracket 1 and is fixed with an oil pumping assembly communicated with it. The connecting pipe 13, the mounting pipe 15, the mounting pipe 2 16 and the oil pumping assembly are all installed with a solenoid valve 17. Two solenoid valves 20 are installed on the oil inlet pipe 7, and the mounting pipe 15 and the connecting pipe 13 are located between the two solenoid valves 20. The negative pressure pump 14 is a rotary vane vacuum pump.

[0029] The oil pumping assembly includes a square tube 22 and an oil suction head 23. The square tube 22 is connected to the connecting pipe 13. There are several oil suction heads 23 and they are all installed on the lower side of the square tube 22.

[0030] When the oil injection operation is implemented, the two solenoid valves 20 on the oil inlet pipe 7 need to be opened, and then the three solenoid valves 17 need to be closed to ensure that the oil pump 6 can pump oil normally.

[0031] When the oil mist needs to be recovered after the oil spraying process is completed, the staff can close the two solenoid valves 20 and open the three solenoid valves 17. Then the negative pressure pump 14 can be started. The suction force generated by the negative pressure pump 14 can suck the oil mist inside the bracket 1 into the multiple oil suction heads 23. Figure 1 and 2 As shown, it then enters the square tube 22, the connecting tube 13, the oil inlet pipe 7, the installation pipe 1 15, the negative pressure pump 14 and the oil-gas separator 21 in sequence. The oil-gas separator 21 separates the oil and gas, discharges the air to the outside, and sends the oil to the installation pipe 2 16. Finally, the recovered oil is returned to the oil tank 4 through the oil inlet pipe 7, the hose 8 and the cannula 5, which can effectively reduce the waste of oil mist and reduce the production cost. It should be noted that the device needs to be cleaned regularly and should be placed in a dust-free and sterile environment as much as possible to ensure the quality and sanitary conditions of the recovered oil mist.

[0032] The nozzles 12 and the oil suction heads 23 are both installed with pressure regulating valves 10, which are used to adjust the pressure inside the nozzles 12 and the oil suction heads 23 to ensure uniform oil spraying by the multiple nozzles 12 and uniform oil suction by the multiple oil suction heads 23.

[0033] Compared with the prior art, the advantages of this application are:

[0034] 1. The filter element prevents external particles from entering the nozzle 12, ensuring that the interior of the nozzle 12 remains clean for a long time, thus complying with food safety regulations. In addition, multiple nozzles 12 share a single filter element, and the filter element and nozzle 12 are detachably connected, making it easy for workers to install or remove the filter element from the bottom of multiple nozzles 12 at one time, resulting in efficient installation and removal.

[0035] 2. The negative pressure suction component and the oil pump 6 share the oil inlet pipe 7, which has a compact and neat structure, rationally utilizes resources, and reduces the size of the device;

[0036] 3. The interior of the bracket 1 is in a relatively closed environment, which can greatly reduce the diffusion of oil mist into the working environment. In addition, with the use of the negative pressure suction component, the excess oil mist inside the bracket 1 can be recovered, reducing resource waste and reducing the pollution of the working environment by oil mist.
