[0002] With the improvement of people's living standards, pastries have gradually appeared in fast food restaurants to meet the dietary needs of different people. With the development of chain catering, existing chain fast food restaurants usually produce dishes, staple foods, and pastries in a central kitchen to ensure the unified taste and quality stability of the food.
[0003] In order to improve the production efficiency of pastries, when producing pastries in a central kitchen, an automated production line is usually used for pastry production; however, some pastries usually need to be brushed with food oil on the surface of the pastry dough before entering the baking process to enhance the taste of the pastries after baking.
[0004] Currently, there are two ways to brush food oil on the pastry dough. One is that workers need to dip a brush in edible oil and then brush it on the surface of the pastry dough. This method has low efficiency and affects the production efficiency of pastries. The other is to add a spraying pipe for spraying edible oil on the equipment to spray the pastry dough with the spraying pipe. However, this method has the defects of uneven spraying and uncontrollable spraying area, which affects the taste of the pastries and causes waste of edible oil. Utility Model Content
[0005] This application provides an oiling device for the surface of pastries during production to ensure the production efficiency of pastries, the taste of pastries, and avoid waste of edible oil.
[0006] The technical solution adopted in this application is as follows:
[0007] An oiling device for the surface of pastries during production includes an oil storage box and an oiling brush provided on the oil storage box. The interior of the oil storage box has an oil storage cavity. An oil outlet hole communicating with the oil storage cavity is provided outside the oil storage box, so that the edible oil in the oil storage cavity flows to the oiling brush through the oil outlet hole. A plurality of oil outlet holes are arranged along the length direction of the oil storage box. The oil storage box is provided with a plugging member, and the plugging member is movably connected to the oil storage box, so that the plugging member can plug at least part of the oil outlet holes.
[0008] By adopting the above technical solution, when using the surface oiling device in this application to oil the pastry dough pieces, the oil storage box is installed on the production equipment, and then edible oil is poured into the oil storage box so that the edible oil is stored in the oil storage cavity. Subsequently, the edible oil in the oil storage cavity flows through the oil outlet holes to the oiling brush and flows downward along the oiling brush. When the production equipment transports the pastry dough pieces to the baking tray, the bottom of the oiling brush contacts the pastry dough pieces, so that the edible oil on the oiling brush is brushed onto the pastry dough pieces, realizing the automatic brushing of edible oil on the pastry dough pieces, and thus ensuring the production efficiency of the pastries. Since the blocking member can block at least part of the oil outlet holes, the effective oiling area of the oiling brush can be adjusted, thereby avoiding the waste of edible oil and increasing the uniformity of the brushing of edible oil to ensure the edible taste of the pastries.

The blocking column can extend into the oil outlet holes to block the oil outlet holes.
[0014] By adopting the above technical solution, when adjusting the effective oiling area of the oiling brush, slide the adjusting column, and then the adjusting column drives the sliding block to move. The sliding block slides relative to the inner wall of the oil storage cavity, so that the blocking column extends into the corresponding oil outlet holes or disengages from the corresponding oil outlet holes to block or open the oil outlet holes. In this process, only the adjusting column needs to be slid, thereby reducing the operation difficulty of the staff.
[0015] Optionally, a protruding portion is provided at the bottom of the oil storage box, a connecting portion is extended and provided at the bottom of the sliding block, the plugging column is arranged on the connecting portion, and when the sliding block abuts against the top of the protruding portion, there is a gap between the connecting portion and the inner wall of the protruding portion, and the plugging column extends into the oil outlet hole.
[0016] By adopting the above technical solution, since the plugging column is arranged on the connecting portion, the length of the plugging column is shortened, so as to ensure the structural strength of the plugging column, thereby avoiding the situation that the plugging column is easily deformed and cannot plug the oil outlet hole; when the sliding block abuts against the top of the protruding portion, there is a gap between the connecting portion and the inner wall of the protruding portion, and the plugging column extends into the oil outlet hole. On the one hand, it realizes the reminder to the staff to avoid the situation of excessive operation when the staff plugs the oil outlet hole. On the other hand, it ensures that after some of the oil outlet holes are plugged, the edible oil can flow normally in the oil storage cavity.
[0017] Optionally, the plugging column has elasticity, and when the plugging column extends into the oil outlet hole, the plugging column undergoes elastic deformation in its radial direction.
[0018] By adopting the above technical solution, since the plugging column has elasticity, and when the plugging column extends into the oil outlet hole, the plugging column undergoes elastic deformation in its radial direction, the plugging effect of the plugging column on the oil outlet hole is increased, so as to increase the sealing performance between the two, and further avoid the waste of edible oil, so as to reduce the production cost of pastries and ensure the cleanliness of the production environment.
[0019] Optionally, a guiding surface is arranged along the circumferential direction at the bottom of the plugging column.
[0020] By adopting the above technical solution, since a guiding surface is arranged along the circumferential direction at the bottom of the plugging column, the diameter of one end at the bottom of the plugging column is reduced, so that when the plugging column extends into the oil outlet hole, one end at the bottom of the plugging column can guide the plugging column, so as to reduce the difficulty of the plugging column extending into the oil outlet hole.
[0021] Optionally, a blocking piece is arranged at the top of the adjusting column, and the diameter of the blocking piece is larger than the diameter of the adjusting column.

[0023] Optionally, the adjusting column is provided with an indicating arrow pointing downward. When the plugging column extends into the oil outlet hole, at least part of the indicating arrow is located in the oil storage box.
[0024] By adopting the above technical solution, since the adjusting column is provided with an indicating arrow pointing downward, the indicating arrow can then remind the staff of the direction for operating the adjusting column to plug the oil outlet hole, so as to achieve the effect of facilitating the staff to plug the oil outlet hole. And when the plugging column extends into the oil outlet hole, at least part of the indicating arrow is located in the oil storage box, so that the indicating arrow can remind the staff that the plugging column has extended into the oil outlet hole, that is, the oil outlet hole has been plugged, thereby improving the use experience of the staff.
[0025] Optionally, an oil filling port is provided on the side of the oil storage box.
[0026] By adopting the above technical solution, since an oil filling port is provided on the side of the oil storage box, edible oil can then be poured into the oil storage cavity through the oil filling port, or the oil storage cavity can be directly connected to an oil barrel using a pipeline, so as to achieve the effect of facilitating the replenishment of edible oil into the oil storage cavity.
[0027] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

[0043] Refer to Figures 1 to 4 , a surface oiling device for pastry production is disclosed, which includes an oil storage box 1 and an oiling brush 2 provided on the oil storage box 1. The oil storage box 1 has an oil storage cavity 11 inside, and an oil outlet hole 12 communicating with the oil storage cavity 11 is provided outside the oil storage box 1, so that the edible oil in the oil storage cavity 11 flows to the oiling brush 2 through the oil outlet hole 12. A plurality of oil outlet holes 12 are arranged along the length direction of the oil storage box 1. The oil storage box 1 is provided with a blocking member 3, and the blocking member 3 is movably connected to the oil storage box 1, so that the blocking member 3 can block at least part of the oil outlet holes 12.
[0044] When using the surface oiling device in this application to oil the pastry dough pieces, install the oil storage box 1 on the production equipment, and then pour edible oil into the oil storage box 1 so that the edible oil is stored in the oil storage cavity 11. Subsequently, the edible oil in the oil storage cavity 11 flows through the oil outlet holes 12 to the oiling brush 2 and flows downward along the oiling brush 2. When the production equipment transports the pastry dough pieces to the baking tray, the bottom of the oiling brush 2 contacts the pastry dough pieces, so that the edible oil on the oiling brush 2 is brushed onto the pastry dough pieces, realizing automatic oiling of the pastry dough pieces, and thus ensuring the production efficiency of the pastries. Since the blocking member 3 can block at least part of the oil outlet holes 12, the effective oiling area of the oiling brush 2 can be adjusted, avoiding waste of edible oil and increasing the uniformity of oil brushing of the edible oil, so as to ensure the edible taste of the pastries.
[0045] This application does not specifically limit the position of the blocking member 3, and it can adopt any one of the following implementation manners:
[0046] Embodiment 1. In this embodiment, refer to Figure 1 , the oil storage box 1 has an intermediate section and adjustable sections at both ends of the intermediate section. The blocking member 3 is arranged in the adjustable section, so that the effective oiling areas at both ends of the oil storage box 1 in its own length direction can be adjusted, achieving the effect of facilitating the adjustment of the effective oiling area of the oil storage box 1.
[0047] Embodiment 2. In this embodiment, refer to Figure 4 , a plurality of blocking members 3 are arranged along the length direction of the oil storage box 1, and the blocking members 3 are arranged in one-to-one correspondence with the oil outlet holes 12, further increasing the flexibility of the surface oiling device. At the same time, when the production equipment stops working, all the oil outlet holes 12 can be blocked to avoid waste of edible oil.
[0048] Preferably, the plurality of blocking members 3 in the middle of the oil storage box 1 in the length direction are connected as a whole to reduce the number of blocking members 3 required for operation when blocking all the oil outlet holes 12, so as to improve the blocking efficiency of the oil outlet holes 12.
[0049] This application does not specifically limit the position of the oil outlet holes 12. Preferably, the bottom of the oil storage box 1 has a protruding portion 13, and the width of the protruding portion 13 gradually decreases from top to bottom. The oil outlet holes 12 are arranged at the bottom of the protruding portion 13, so that the edible oil in the oil storage box 1 can flow to the oiling brush 2 as much as possible to avoid waste of edible oil. The oiling brush 2 is arranged on both sides of the protruding portion 13, so that the edible oil flowing out of the oil outlet holes 12 flows downward from the inside of the oiling brush 2 to increase the cleanliness of the oiling brush 2.
[0050] In other embodiments, the oil outlet hole 12 may also be provided on the side of the oil storage box 1, so that the cooking oil flows from the side of the oil storage box 1 to the oiling brush 2.
[0051] The present application does not specifically limit the structure of the plugging member 3. Preferably, referring to Figure 2 and Figure 3 , the plugging member 3 includes a sliding block 31 provided in the oil storage cavity 11, a plugging column 32 provided at the bottom of the sliding block 31, and an adjusting column 33 provided at the top of the sliding block 31 and passing through the oil storage box 1. The plugging column 32 can extend into the oil outlet hole 12 to plug the oil outlet hole 12.
[0052] It can be understood that the opposite sides of the sliding block 31 respectively abut against the opposite two cavity walls of the oil storage cavity 11, so that the sliding block 31 can guide the plugging column 32 to increase the stability of the movement of the plugging column 32.
[0053] When adjusting the effective oiling area of the oiling brush 2, slide the adjusting column 33, and then the adjusting column 33 drives the sliding block 31 to move. The sliding block 31 slides relative to the cavity wall of the oil storage cavity 11, so that the plugging column 32 extends into the corresponding oil outlet hole 12 or disengages from the corresponding oil outlet hole 12, so as to block or open the oil outlet hole 12. In this process, only the adjusting column 33 needs to be slid, thereby reducing the operation difficulty of the staff.
[0054] Further, referring to Figure 2 and Figure 3 , a protruding portion 13 is provided at the bottom of the oil storage box 1, a connecting portion is extended and provided at the bottom of the sliding block 31, and the plugging column 32 is provided on the connecting portion, thereby shortening the length of the plugging column 32 to ensure the structural strength of the plugging column 32, so as to avoid the situation that the plugging column 32 is easily deformed and cannot plug the oil outlet hole 12; when the sliding block 31 abuts against the top of the protruding portion 13, there is a gap between the connecting portion and the inner wall of the protruding portion 13, and the plugging column 32 extends into the oil outlet hole 12. On the one hand, it realizes the reminder to the staff to avoid the situation of over-operation when the staff plugs the oil outlet hole 12. On the other hand, it ensures that after some of the oil outlet holes 12 are plugged, the cooking oil can flow normally in the oil storage cavity 11.
[0055] Further, the plugging column 32 has elasticity. When the plugging column 32 extends into the oil outlet hole 12, the plugging column 32 elastically deforms in its radial direction, thereby increasing the plugging effect of the plugging column 32 on the oil outlet hole 12 to increase the sealing performance between the two, and further avoiding the waste of cooking oil, so as to reduce the production cost of pastries and ensure the cleanliness of the production environment.
[0056] The present application does not specifically limit the material for manufacturing the plug column 32. Preferably, the plug column 32 is made of silica gel material. In other embodiments, the plug column 32 can also be made of rubber or other elastic materials.
[0057] Furthermore, referring to Figure 3 , a guiding surface 321 is provided along the circumferential direction of the bottom of the plug column 32, thereby reducing the diameter of one end of the bottom of the plug column 32. When the plug column 32 extends into the oil outlet hole 12, one end of the bottom of the plug column 32 can guide the plug column 32, so as to reduce the difficulty of the plug column 32 extending into the oil outlet hole 12.
[0058] Further, referring to Figure 2 and Figure 3 , a blocking piece 331 is provided at the top of the adjusting column 33. The diameter of the blocking piece 331 is larger than that of the adjusting column 33. Thus, when an operator operates the adjusting column 33, the blocking piece 331 can be grasped, so that the blocking piece 331 drives the adjusting column 33 to move, avoiding the situation that the operator's hand is prone to slipping when operating the adjusting column 33, and thus improving the operation efficiency of the adjusting column 33.
[0059] Further, referring to Figure 2 and Figure 3 , the adjusting column 33 is provided with an indicating arrow 322 pointing downward. When the plug column 32 extends into the oil outlet hole 12, at least part of the indicating arrow 322 is located in the oil storage box 1.
[0060] Since the adjusting column 33 is provided with the indicating arrow 322 pointing downward, the indicating arrow 322 can remind the operator of the direction to operate the adjusting column 33 to block the oil outlet hole 12, so as to facilitate the operator to block the oil outlet hole 12. And when the plug column 32 extends into the oil outlet hole 12, at least part of the indicating arrow 322 is located in the oil storage box 1, so that the indicating arrow 322 can remind the operator that the plug column 32 has extended into the oil outlet hole 12, that is, the oil outlet hole 12 has been blocked, thereby improving the operator's use experience.
