Description

Technical Field

[0001] The utility model relates to a novel drying machine, belonging to the field of mushroom drying equipment. Background Art

[0002] When cultivated edible mushrooms are harvested, a small portion is sold fresh, but the vast majority must be dried before being shipped to various markets. Existing dryers have a hot air inlet at the bottom and an outlet at the top. Between the inlet and outlet are thirteen vertically arranged shelves for placing mushroom trays.

[0003] During the drying process, because the hot air gets hotter as it goes up, even with thirteen layers of drying boxes, it's difficult to finish drying all the mushrooms in one go. After four hours of drying, the drying chamber has to pause to remove the mushrooms from the bottom five layers, flip them upside down, and then continue drying. After another four hours of drying, the drying chamber pauses again to remove the dried mushrooms from the bottom five layers. The process then repeats, flipping the mushrooms from the top five layers and placing them on the bottom five layers for drying. When they're dry, the process repeats again. This results in a long drying time, low efficiency, and high labor intensity for operators. To meet the needs of mushroom farmers, improvements to the relevant equipment are needed.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] like Figures 1 to 7 As shown, this embodiment provides a new type of dryer, including a drying box 1, wherein the interior of the drying box is vertically provided with several layers of storage shelves 2, the inner top and inner bottom of the drying box are provided with hot air inlet components, and the inner middle of the drying box or a position near the inner middle is provided with a hot air exhaust component.

[0028] The storage shelves are composed of a left supporting angle iron and a right supporting angle iron, which are used to support the placement of mushrooms / mushroom trays (not shown in the figure).

[0029] Wherein, the hot air exhaust component is located on the back side of the drying box.

[0030] In this embodiment of the utility model, the storage shelves are mounted on a movable frame 3, the bottom of which is provided with movable wheels 4 to facilitate the movable frame to be pushed into or out of the drying box. After cleaning, the mushrooms are placed on the mushroom baskets, which are then directly placed on the storage shelves of the movable frame that is pushed out of the drying box.

[0031] Wherein, the left and right supporting angle irons are welded and fixed on the movable frame.

[0032] Wherein, the movable frame is a cubic frame, and its front, back, left, right, top and bottom are not closed.

[0033] The movable wheels are all universal wheels with brakes, which are screwed to the bottom of the movable frame. The movable frame can be moved in and out of the drying box more freely, which reduces the difficulty of operation.

[0034] The inner bottom surface of the drying box is fixedly connected with a support grid 5 above the bottom hot air inlet assembly for supporting the movable frame, and the support grid is flush with the ground to facilitate the pushing and ejecting of the movable frame.

[0035] In an embodiment of the present invention, the movable frame is horizontally provided with a partition 6 at a horizontal height position corresponding to the exhaust hot air component. Several layers of storage shelves above the partition form an upper storage area 7 as a whole, and several layers of storage shelves below the partition form a lower storage area 8 as a whole.

[0036] Among them, the partition is welded and fixed on the movable frame, and uses dual heat sources and is divided into upper and lower parts. That is, most of the hot air blown upward is blocked by the partition and concentrated in the lower storage area, and most of the hot air blown downward is blocked by the partition and concentrated in the upper storage area, so that the upper and lower storage areas are dried by hot air in different areas, the heat of the hot air is guaranteed, and the drying efficiency is high.

[0037] In an embodiment of the present invention, the hot air exhaust assembly includes an upper exhaust fan 9 and a lower exhaust fan 10 installed on the exhaust port. The horizontal height position of the upper exhaust fan corresponds to the bottom of the upper storage area, and the horizontal height position of the lower exhaust fan corresponds to the top of the lower storage area.

[0038] The upper exhaust fan guides and discharges the hot air in the upper storage area from top to bottom, and the lower exhaust fan guides and discharges the hot air in the lower storage area from bottom to top.

[0039] In the embodiment of the present invention, an entrance and exit are provided on the front of the drying box, and a switch door 11 is provided on the entrance and exit.

[0040] The switch door opens when the movable frame needs to be pushed out, and closes after the movable frame is pushed in.

[0041] Wherein, one side portion of the switch door is hinged on the entrance and exit to realize rotation opening and closing.

[0042] In the embodiment of the present invention, the hot air inlet components include an air inlet pipeline 12 , and a heat exchanger 13 and an air inlet fan 14 are provided inside the air inlet pipeline.

[0043] Wherein, the heat exchanger is a fin-type radiator.

[0044] The air inlet pipe is used to take in cold air, which is converted into hot air after contacting with the fins of the heat exchanger for heat exchange, and the hot air is then blown into the drying box by the air inlet fan.

[0045] In the embodiment of the present invention, a waste heat recovery pipeline 15 is connected to the exhaust port of the hot air exhaust component, and the waste heat recovery pipeline is connected to the air inlet pipelines at the top and bottom of the drying box.

[0046] The waste heat recovery pipeline is used to receive the hot air / waste heat discharged from the exhaust port.

[0047] In an embodiment of the present utility model, the waste heat recovery pipeline is provided with an air outlet 16 directly opposite the exhaust port, the air outlet is provided with an air outlet gate 17, and the air inlet pipeline is provided with an air inlet gate 18. The air inlet gates are located on the rear side of the connection between the waste heat recovery pipeline and the air inlet pipeline, and the heat exchanger and the air inlet fan are located on the front side of the connection between the waste heat recovery pipeline and the air inlet pipeline.

[0048] Among them, an isolation plate 19 is provided inside the waste heat recovery pipeline between the upper exhaust fan and the lower exhaust fan. The isolation plate isolates the upper exhaust fan, the upper part of the air outlet, the upper part of the waste heat recovery pipeline, and the top hot air inlet component from the lower exhaust fan, the lower part of the air outlet, the lower part of the waste heat recovery pipeline, and the bottom hot air inlet component to achieve:

[0049] When the air inlet gate is open and the air outlet gate is fully open: on the one hand, fresh cold air enters the air inlet pipe, and the cold air contacts the fins of the heat exchanger for heat exchange and becomes hot air, which is then blown into the drying box by the air inlet fan; on the other hand, most of the hot air discharged by the upper exhaust fan is discharged from the air outlet, and a small part goes up through the waste heat recovery pipeline to merge with the cold air, and then enters the top hot air inlet component for a second time; most of the hot air discharged by the lower exhaust fan is discharged from the air outlet, and a small part goes down through the waste heat recovery pipeline to merge with the cold air, and then enters the bottom hot air inlet component for a second time, forming a Figure 1 The external circulation drying mode shown saves energy and thus reduces drying costs.

[0050] In the above external circulation drying mode, the air inlet gate can also be opened and the air outlet gate can be completely closed, so that all the residual heat can be combined with the cold air and then flow into the hot air inlet component (not shown in the figure).

[0051] When the air inlet gate is closed and the air outlet gate is fully closed: fresh cold air no longer enters the air inlet pipe. The hot air discharged by the upper exhaust fan all goes up through the waste heat recovery pipe and enters the top hot air inlet component for the second time; the hot air discharged by the lower exhaust fan all goes down through the waste heat recovery pipe and enters the bottom hot air inlet component for the second time, forming a Figure 2 The internal circulation drying mode shown saves energy and thus reduces drying costs.

[0052] In an embodiment of the present invention, water vapor interceptors are provided above and below the exhaust port / outlet inside the waste heat recovery pipeline.

[0053] Wherein, the water vapor interceptor is used to intercept part of the water vapor in the waste heat.

[0054] In the embodiment of the present utility model, the water vapor interceptor includes a water absorption component 20 with water absorption material, and a water receiving component 21 is provided below the water absorption component. The water receiving component includes a water receiving tray, and the water receiving tray is provided with a plurality of air holes 22, and the water receiving tray is connected to a drainage pipe 23 leading to the outside.

[0055] The water-absorbing components each include a non-woven fabric 24, which is secured to a frame 25 on all sides. A slot 26 for the frame is provided in the waste heat recovery pipeline, and the frame is inserted into the waste heat recovery pipeline through the slot, thereby enclosing the waste heat recovery pipeline on all sides. When waste heat passes through the non-woven fabric, the hot air can pass through it, while most of the water vapor is intercepted by the non-woven fabric, causing it to gradually become moist.

[0056] The water receiving pan is installed obliquely in the waste heat recovery pipeline, with its lower end leaning against the top notch of the water receiving trough 27, and the bottom of the water receiving trough is connected to the drain pipe.

[0057] The side cross-section of the water receiving tray is wavy, and a plurality of air holes are arranged in the crest area thereof.

[0058] The top surface of the isolation plate is provided with a water collecting trough 28 , which is connected to a drainage pipe.

[0059] When the non-woven fabric gradually becomes damp enough to drip, the non-woven frame can be removed from the slot and a new one inserted. If the non-woven fabric is not replaced promptly, the drip tray will catch some of the dripping water droplets, which will flow down the tray into the trough and then drain through the drainpipe. The remaining water droplets not caught by the drip tray (including those dripping from the tray and from the vents) will: 1. For the upper portion of the waste heat recovery pipeline, these droplets will either drip into the sump on the isolation plate and drain through the drainpipe, or be blown upward by the wind to the heat exchanger fins, where they evaporate. 2. For the lower portion of the waste heat recovery pipeline, these droplets will drip and be blown downward by the wind to the heat exchanger fins, where they evaporate. Overall, this does not affect the dryer's operation.

[0060] In this embodiment of the utility model, the new dryer is installed on a raised platform 29, wherein the bottom hot air inlet assembly is located below the raised platform floor. The drying box is provided with a slag removal port and a slag removal door 30 next to the air inlet fan at the bottom. This facilitates the operator to open the slag removal door below the raised platform floor to clean up fallen mushroom slag.

[0061] In the embodiment of the present invention, the operating principle of the new dryer is as follows: during the drying process, hot air from the bottom of the dryer is blown upward and discharged through the hot air exhaust assembly, drying the mushrooms on the shelves in the bottom area; hot air from the top of the dryer is blown downward and discharged through the hot air exhaust assembly, drying the mushrooms on the shelves in the top area. This solves the problem of low heat in the upper area of the dryer in the prior art, achieving shorter drying times, higher efficiency, and reduced labor intensity for operators.

[0062] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
