Description

Technical Field

[0001] The invention belongs to the technical field of braised goose production lines, and particularly relates to an oil spraying device for braised goose. Background Art

[0002] In the production process of stewed goose, after the goose is stewed and drained, it is usually necessary to brush a layer of oil on the surface of the goose to improve the shelf life and taste of the stewed goose. At present, the conventional operation method is to manually take the goose and place it on the operating table, and then use a brush to brush the oil on the surface of the goose. Obviously, this operation method has the problem of low efficiency (usually it takes nearly one minute to brush the oil relatively evenly for each stewed goose), and it is impossible to master the uniformity of brushing the oil, and the waste of oil is also large.

[0003] In the existing method, document CN111136053A discloses a gear high-pressure steam cleaning and oil spraying device, including a device housing, a No. 1 partition extending upward and a No. 2 partition fixed on the right side of the No. 1 partition and a No. 3 partition fixed on the right side of the No. 2 partition fixed on the bottom wall of the device housing, a loading cavity is fixed between the No. 1 partition and the left inner wall of the device housing, and a fixed cleaning cavity is provided between the No. 1 partition and the No. 2 partition. Although this solution can be used for assembly line work, improve work efficiency, save labor costs, and recycle excess oil mist, it has the problems of complex structure and large space occupation, and it is difficult to achieve uniform oil spraying. More importantly, when using this assembly line oil spraying method, a lot of oil is lost due to adhering to the workpiece and its hanging rail. How to reduce this part of oil loss is a technical problem that needs to be solved. Summary of the invention

[0004] The object of the present invention is to provide a braised goose oil spraying device, which can at least solve the problems mentioned in the background technology.

[0005] The present invention adopts the following technical solution.

[0006] A braised goose oil spraying device comprises an oil sprayer and a vertically arranged tower body, wherein the oil sprayer is arranged at the bottom of the tower body, and the oil mist sprayed from the oil sprayer from bottom to top fills the inner cavity of the tower body, and when the braised goose is placed in the inner cavity of the tower body, the oil mist adheres to the surface of the braised goose. Preferably, the oil sprayer is an ultrasonic atomizer.

[0007] Furthermore, the tower body is provided with an inlet and an outlet, and door curtains are provided at the inlet and the outlet. The door curtains are composed of a plurality of silicone strips arranged closely and suspended. When the silicone strips are in a free hanging state, the gap between adjacent silicone strips is zero (without considering error factors).

[0008] Furthermore, it also includes a movable hanging rail for hanging the braised goose, and the movable hanging rail passes through the inlet and the outlet of the tower body.

[0009] Furthermore, an oil collecting plate is arranged above the atomizer and in the inner cavity of the tower body, an oil return pipe is arranged at the low point of the oil collecting plate, and the oil return pipe is connected to the oil inlet of the atomizer.

[0010] Preferably, the upper edge of the oil collecting plate is connected to the inner wall of the tower body, the lower edge of the oil collecting plate is connected to the tower body shell, and the angle between the oil collecting plate and the horizontal plane is not less than 15°.

[0011] Furthermore, there are multiple movable hanging rails, and all the movable hanging rails are located at different heights in the inner cavity of the tower body. With such a structure, the space occupied by the tower body can be further saved.

[0012] Preferably, the power system of the atomizer and the mobile hanging rail is connected to a controller, and the processor of the controller implements at least the following functions when executing the program: Step A1, controlling the power system to operate, causing the movable hanging rail to move forward at a set speed, and controlling the power system to pause when the suspended marinated goose enters the tower body cavity; Step A2, controlling the atomizer to open at a set time point so that the inner cavity of the tower body is filled with oil mist.

[0013] Preferably, the power system of the atomizer and the mobile hanging rail is connected to a controller, and the processor of the controller implements at least the following functions when executing the program: Step B1, controlling the power system to operate, so that the movable hanging rail always moves forward at a set speed; Step B2, control the atomizer to open so that the inner cavity of the tower body is always filled with oil mist.

[0014] Preferably, the silica gel strip is a cylindrical strip with a diameter of 3-5 mm, and the lower section of the silica gel strip is close to the inner wall of the tower body. With such a structure, oil waste can be better prevented.

[0015] In order to further reduce the loss of oil, a number of steel needles arranged in an array are arranged on the inner wall of the tower top cover. The steel needles are stainless steel injection needles with a diameter of no more than 5mm. The top of the stainless steel injection needles is closed, and the spacing between adjacent steel needles is no more than 3mm. The tower top cover is made of silicone that can be inserted by the steel needles without falling off. The first part of the steel needles located on both sides of the walking track of the stewed goose are arranged vertically, and the second part of the steel needles located directly below the walking track of the stewed goose are arranged obliquely, and the needle tips of the second part of the steel needles are located on the side of the walking track of the stewed goose. Compared with the traditional oil injection method of the assembly line, this solution can reduce oil loss by more than 50%.

[0016] Beneficial effects: Compared with the existing conventional oiling operation mode, the present invention can achieve an efficiency of at least twelve braised geese per minute, which significantly improves the work efficiency of evenly coating the surface of the braised goose with oil; more importantly, the present invention greatly simplifies the equipment for evenly coating the surface of the braised goose with oil, which not only significantly reduces its footprint, but also the required width of the footprint can be controlled within sixty centimeters. It can be directly installed at the entrance of the food workshop, which is beneficial to ensuring the hygiene in the food workshop, and can easily and long-term achieve even oil coating. It is very convenient to operate and can significantly reduce oil waste, especially the amount of oil waste attached to the mobile hanging rail can be greatly reduced.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0019] Combination Figures 1 to 4 As shown, a braised goose oil spraying device comprises an oil sprayer 1 and a tower body 2 arranged vertically and installed at the entrance of a food workshop. The oil sprayer 1 is arranged at the bottom of the tower body 2. The oil mist sprayed from the oil sprayer 1 from bottom to top fills the inner cavity 3 of the tower body. When the braised goose is placed in the inner cavity 3 of the tower body, the oil mist adheres to the surface of the braised goose. Among them, the oil sprayer 1 adopts an ultrasonic atomizer (rated power 25W, evaporation capacity 250-300ml / h). An inlet 4 and an outlet 5 are arranged on the tower body 2. A door curtain 6 is arranged at the inlet 4 and the outlet 5. The door curtain 6 is composed of a plurality of silicone strips 7 arranged closely and suspended. When the silicone strips 7 are in a free hanging state, the gap between adjacent silicone strips 7 is zero; the silicone strips 7 are cylindrical strips with a diameter of 3mm, and the lower section of the silicone strips 7 is close to the inner wall of the tower body 2.

[0020] In this embodiment, a mobile hanging rail 8 for hanging the marinated goose is also included, and the mobile hanging rail 8 passes through the inlet 4 and the outlet 5 of the tower body 2. An oil collecting plate 9 is arranged above the injector 1 and located in the inner cavity 3 of the tower body, and an oil return pipe 10 is arranged at the low point of the oil collecting plate 9, and the oil return pipe 10 is connected to the oil inlet of the atomizer. The upper edge of the oil collecting plate 9 is connected to the inner wall of the tower body, and the lower edge of the oil collecting plate 9 is connected to the shell of the tower body 2, and the angle between the oil collecting plate 9 and the horizontal plane is 25°.

[0021] In this embodiment, three movable hanging rails 8 are arranged, and all movable hanging rails 8 are located at different heights in the tower body inner cavity 3. Among them, the three movable hanging rails 8 near the inlet 4 are first arranged in parallel and separated from each other, and then the three movable hanging rails 8 rise to different heights, enter the tower body inner cavity 3 from the inlet 4, and pass through the outlet 5.

[0022] In this embodiment, the power system of the atomizer and the mobile hanging rail 8 is connected to the controller, and the processor of the controller implements at least the following functions when executing the program (control scheme 1): Step A1, control the power system to operate, and make the movable hanging rail 8 move forward at a set speed, and when the suspended marinated goose enters the tower body cavity 3, control the power system to pause; Step A2, controlling the atomizer to start at a set time point so that the inner cavity 3 of the tower body is filled with oil mist.

[0023] In this embodiment, the power system of the atomizer and the mobile hanging rail 8 is connected to the controller, and the processor of the controller implements at least the following functions when executing the program (control scheme 2): Step B1, controlling the power system to operate, so that the movable hanging rail 8 always moves forward at a set speed 2; Step B2, control the atomizer to open so that the inner cavity 3 of the tower body is always filled with oil mist.

[0024] According to the calculation of the tower body 2 with an inner diameter of 55 cm in this example, the number of braised geese located in the inner cavity 3 of the tower body in the same period is 12 to 15. Therefore, compared with the existing conventional oiling operation method (manually using a brush to dip oil and brush it on the braised goose, and each braised goose needs nearly one minute to be relatively evenly oiled), this embodiment can achieve an efficiency of at least twelve braised geese per minute, which significantly improves the work efficiency of evenly coating the surface of the braised goose with oil. More importantly, this solution greatly simplifies the equipment for evenly coating the surface of the braised goose with oil, not only significantly reducing its floor space, the required width of the floor space can be controlled within sixty centimeters, and it can be directly installed at the entrance of the food workshop, which is conducive to ensuring the hygiene in the food workshop, and can easily and long-term achieve even oil coating, which is very convenient to operate and can significantly reduce oil waste. Example 2

[0025] A braised goose oil spraying device, referring to Example 1 and combining Figure 5 and Figure 6 As shown, the difference from Example 1 is that: a plurality of steel needles arranged in an array are arranged on the inner wall of the top cover of the tower body 2, and the steel needles are stainless steel injection needles with a diameter of 3mm, and the spacing between adjacent steel needles is no more than 3mm. The top cover of the tower body 2 is made of silicone that can be inserted by the steel needles without falling off; the first part of the steel needles 11 located on both sides of the walking track of the stewed goose are arranged vertically, and the second part of the steel needles 12 located directly below the walking track of the stewed goose are arranged obliquely, and the needle tips of the second part of the steel needles 12 are located on the side of the walking track of the stewed goose. Compared with the embodiment, this embodiment has further advantages including: it can significantly reduce the waste of oil, especially it can greatly reduce the waste of oil attached to the mobile hanging rail.

[0026] Comparative Example 1, the braised goose oil spraying device refers to Example 1, and the difference between it and Example 1 is that: the door curtain 6 is omitted, and an oil spray pump (oil spraying amount 1000ml / h) and an oil storage container are used instead of the ultrasonic atomizer, and a nozzle with an aperture of 2mm is used to spray oil from top to bottom at the braised goose, and the oil dripping from the tower body during the oil spraying process can also be recovered into the oil storage container for recycling.

[0027] Comparative Example 2, the braised goose oil spraying device refers to Example 1, and the difference between it and Example 1 is that the door curtain 6 is omitted.

[0028] Oil loss determination method: add 5 liters of edible oil into each injector, hang multiple braised geese on the hook of the mobile hanging rail, control the power system to operate, and ensure that the mobile hanging rail always moves forward at a set speed of 2 (40 cm / min); control the atomizer in Example 1 and Example 2 to always be turned on, and the inner cavity of the tower body is always filled with oil mist; in Comparative Example 1, 5 liters of edible oil are added to the oil storage container, and whenever the braised goose is directly below the nozzle, the oil injection pump is controlled to be turned on, and each braised goose is continuously sprayed with oil for 30 seconds; in Comparative Example 2, the mobile hanging rail always moves forward at a set speed of 2 (40 cm / min), and the atomizer is controlled to always be turned on.

[0029] The results of the oil loss measurement are as follows: the oil usage time of each injector and oil storage container (from the start of injection to the end of the oil in the injector / oil storage container) is counted. The results are shown in Table 1 below. Table 1 Material usage time plan Fuel usage time Example 1 34.5 hours Example 2 67.6 hours Comparative Example 1 14.2 hours Comparative Example 2 22.7 hours

[0030] In comparative example 1, most of the sprayed oil was attached to the braised goose and the movable hanging rail and lost, and a large amount of oil dripped under the entire walking track of the movable hanging rail (on the ground); in comparative example 2, most of the sprayed oil mist escaped through the inlet 4 and the outlet 5 on the tower body 2 and was wasted, and a small amount attached to the braised goose, and the oil film (i.e., oil) on the braised goose was unevenly attached, and there was no oil film in some areas. In Example 1, a small amount of excess oil attached to the braised goose and the oil attached to the mobile hanging rail are wasted, and a small amount of dripping oil is seen below the traveling track of the mobile hanging rail. Part of the oil dripping from the top of the inner cavity 3 of the tower body directly drips on the mobile hanging rail and the braised goose and is carried away and wasted; in Example 2, very little oil is attached to the mobile hanging rail, and no oil droplets drip directly on the mobile hanging rail. No dripping oil is seen below the traveling track of the mobile hanging rail, and most of the oil is attached to the braised goose. The excess oil mist in the inner cavity 3 of the tower body forms oil drippings that are recycled, especially a large amount of oil mist is collected by steel needles with a specific structure and dripped for recycling.
