Description

Technical Field

[0001] This utility model relates to the field of negative pressure steamer technology, specifically a negative pressure steamer for softening bird's nest. Background Technology

[0002] Some food ingredients require a pre-treatment process of steaming and softening before processing, and negative pressure steamers are commonly used for this process. Existing negative pressure steamers require the ingredients to be placed on trays, which are then stacked layer by layer inside the steamer. This stacking method makes it difficult to ensure uniform temperature and humidity distribution to each layer of ingredients within the steamer, easily leading to over-softening or under-softening of certain layers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a negative pressure steamer that can spray airflow onto each tray individually, so as to increase the airflow circulation speed above any layer of raw materials in the steamer, improve the uniformity of steaming, improve the softening effect, and shorten the steaming time.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A negative pressure steamer for softening bird's nest includes two symmetrically arranged functional compartments, each containing several layers of supports for holding raw material trays; a layer-by-layer jetting mechanism is provided between the two functional compartments, the layer-by-layer jetting mechanism comprising:

[0006] Two columns positioned opposite each other;

[0007] Two sets of roller shutter assemblies are symmetrically arranged between the two columns. Each roller shutter assembly includes a guide cloth and two sets of winding components arranged at both ends of the columns. The upper and lower ends of the guide cloth are respectively wound around the two winding components. The guide cloth has airflow holes. The airflow holes of the two roller shutter assemblies correspond to each other, and the upper ends of the two airflow holes are connected to baffles. The baffles, the two airflow holes, and the two guide cloths form an airflow channel with a T-shaped cross section. The bottom of the airflow channel is connected to the gas input hole at the bottom of the negative pressure steamer.

[0008] The two guide cloths are simultaneously extended and retracted to raise and lower the baffle plate, thereby raising and lowering the airflow through hole to correspond to the layer support of any layer.

[0009] In one embodiment of this utility model, two outer baffles are symmetrically arranged on the inner side of the column, and two inner baffles are symmetrically arranged between the two outer baffles. The inner baffles and the outer baffles form a limiting gap, and the side of the guide cloth is located between the limiting gaps to guide the opening and closing of the guide cloth.

[0010] In one embodiment of this utility model, the winding component includes a roller shaft and a winding roller sleeved on the roller shaft. The winding roller is keyed to the roller shaft, and the upper or lower end of the guide cloth is wound around the winding roller.

[0011] One end of the roller is rotatably mounted on one side of the column, and the other end of the roller passes through the other side of the column and the negative pressure steamer and is fitted with a roller gear. The roller gears of the two winding components at the upper or lower end of the column mesh with each other.

[0012] In one embodiment of this utility model, the end of any of the rollers at the upper end of the column is connected to the output shaft of the drive motor.

[0013] The end of any of the rollers at the lower end of the column is connected to the output shaft of the drive motor.

[0014] In one embodiment of this utility model, the take-up roller is located between the two inner baffles, and the inner baffles protrude from the outer baffles on one side toward the guide cloth, so that when the take-up roller takes up and releases the guide cloth, the outer baffles abut against the guide cloth, thereby preventing the guide cloth from leaving the limiting gap.

[0015] In one embodiment of the present invention, the roller shaft includes a roller shaft connecting part, a roller shaft key part and a roller shaft end part connected in sequence. The roller shaft connecting part passes through the column on one side and is rotatably mounted on the column. The roller shaft key part passes through the take-up roller and is keyed to it. The roller shaft end part is rotatably mounted on the column on the other side.

[0016] In one embodiment of this utility model, the cross-sectional dimension of the roller shaft connecting part is larger than the cross-sectional dimension of the roller shaft key part, and the cross-sectional dimension of the roller shaft key part is larger than the cross-sectional dimension of the roller shaft end.

[0017] In one embodiment of this utility model, the bottom of the negative pressure steamer is provided with a flow guide plate with an annular cross-section between the two functional chambers. The lower end of the flow guide plate is connected to the gas input hole, and the upper end of the flow guide plate abuts against the lower end of the flow guide cloth.

[0018] The beneficial effects of adopting the above technical solution are as follows:

[0019] This application uses two guide cloths, baffles, and two columns to form an airflow channel. The lower end of the airflow channel is connected to the gas inlet at the bottom of the negative pressure steamer. By expanding and contracting the guide cloths, the height of the airflow through the holes can be adjusted, so that the airflow through the holes correspond to any layer of support. This allows for steam jetting or air jetting of the raw materials on the tray, thereby increasing the gas circulation above the raw materials, increasing the uniformity of steaming in the negative pressure steamer, and reducing the softening differences between each layer of raw materials.

[0035] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0036] like Figures 1 to 8 The bird's nest softening negative pressure steaming box shown includes two symmetrically arranged functional compartments. Several layers of supports 200 are arranged within each functional compartment, and these supports 200 are used to hold raw material trays 300. A layer-by-layer jetting mechanism is provided between the two functional compartments. The layer-by-layer jetting mechanism includes:

[0037] The two columns are set opposite each other at 400.

[0038] Two sets of roller blind assemblies are symmetrically arranged between the two columns 400. Each roller blind assembly includes a guide cloth 600 and two sets of winding components arranged at both ends of the column 400. The upper and lower ends of the guide cloth 600 are respectively wound around the two winding components. The guide cloth 600 has airflow holes 601. The airflow holes 601 of the two roller blind assemblies correspond to each other, and the upper ends of the two airflow holes 601 are connected to baffles 602. The baffles 602, the two airflow holes 601 and the two guide cloths 600 form an airflow channel with a T-shaped cross section. The bottom of the airflow channel is connected to the gas input hole at the bottom of the negative pressure steamer 100.

[0039] The two guide cloths 600 are simultaneously extended and retracted to raise and lower the baffle plate 602, thereby raising and lowering the airflow through hole 601 to correspond to any of the layer supports 200.

[0040] In this embodiment, the hot steam jetted out of the airflow channel can individually heat and humidify the raw materials in any layer, increasing the consistency of softening of the raw materials in each layer; the air jetted out of the airflow channel can increase the air circulation above the raw materials in a single layer, reducing the humidity and temperature of that layer.

[0041] See Figures 5 to 7 The inner side of the column 400 is symmetrically provided with two outer baffles 403, and two inner baffles 402 are symmetrically provided between the two outer baffles 403. The inner baffles 402 and the outer baffles 403 form a limiting gap. The side of the guide cloth 600 is located between the limiting gaps to guide the expansion and contraction of the guide cloth 600, while increasing the sealing of the airflow channel and improving the jet effect.

[0042] The winding component includes a roller shaft 501 and a winding roller 500 sleeved on the roller shaft 501. The winding roller 500 is keyed to the roller shaft 501. The upper or lower end of the guide cloth 600 is wound around the winding roller 500.

[0043] One end of the roller shaft 501 is rotatably mounted on one side of the column 400, and the other end of the roller shaft 501 passes through the other side of the column 400 and the negative pressure steaming box 100 and is fitted with a roller shaft gear 502. The roller shaft gears 502 of the two winding components at the upper or lower end of the column 400 mesh with each other to achieve synchronous winding and unwinding of the two guide cloths 600. In this embodiment, a gearbox 700 is provided on the outside of the negative pressure steaming box 100 corresponding to the roller shaft gear, and the roller shaft gear 502 is disposed in the gearbox 700.

[0044] See Figure 2 and Figure 6 The end of any one of the rollers 501 at the upper end of the column 400 is connected to the output shaft of the drive motor 800. The end of any one of the rollers 501 at the lower end of the column 400 is connected to the output shaft of the drive motor 800.

[0045] See Figure 7 The take-up roller 500 is located between the two inner baffles 402. The inner baffles 402 protrude from the outer baffles 403 on one side toward the guide cloth 600, so that when the take-up roller 500 takes up and releases the guide cloth 600, the outer baffles 403 abut against the guide cloth 600, thereby preventing the guide cloth 600 from leaving the limiting gap.

[0046] See Figures 6 to 8 The roller 501 includes a roller connecting part 501-1, a roller key part 501-2, and a roller end part 501-3 connected in sequence. The roller connecting part 501-1 passes through the column 400 on one side and is rotatably mounted on the column 400. The roller key part 501-2 passes through the take-up roller 500 and is keyed to it. The roller end part 501-3 is rotatably mounted on the column 400 on the other side.

[0047] The cross-sectional dimension of the roller connecting part 501-1 is larger than the cross-sectional dimension of the roller key part 501-2, and the cross-sectional dimension of the roller key part 501-2 is larger than the cross-sectional dimension of the roller end 501-3, so that the roller 501 can pass through the column 400 on one side, pass through the take-up roller 500 and then pass through the column 400 on the other side, so as to achieve quick installation.

[0048] The bottom of the negative pressure steam chamber 100 is provided with a flow guide plate 101 with an annular cross section between the two functional chambers. The lower end of the flow guide plate 101 is connected to the gas inlet, and the upper end of the flow guide plate 101 abuts against the lower end of the flow guide cloth 600. With the help of the limiting gap, the airflow can be guided into the airflow channel to reduce diffusion and increase the jet effect.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
