Description

Technical Field

[0001] The utility model relates to the technical field of edible mushroom production equipment, in particular to a morel drying device. Background Art

[0002] Morel is a rare edible fungus belonging to the Basidiomycota. The growth temperature of artificially cultivated morel is between 10°C and 20°C. Too high or too low temperature will affect its growth. Maintaining a relatively high humidity (about 70% to 90%) during the growth process is crucial for the growth of morel, and a dry environment will inhibit its development.

[0003] Morel is usually dried and stored. First, gently brush off the soil on the surface to avoid soaking in water to prevent affecting the taste. If the morel is large, it can be cut into appropriate slices before drying. Too high or too low drying temperature during the drying process may damage its flavor or nutritional components, or may not be dried thoroughly, resulting in mildew in the later stage. In the conventional drying process, direct sunlight will also affect the loss of color and nutritional components, and the drying is insufficient and uneven, causing a large amount of morel to mildew and be wasted. Summary of the Invention

[0006] Drying components are provided on the inner walls of the drying box corresponding to the sides and the top of the multi-layer bracket for alternately supplying steam and cold air. By alternately supplying steam and cold air, the moisture in the morel can be quickly removed, improving the drying efficiency.

[0007] The drying component includes two groups of conveying pipe groups. One group of conveying pipe groups is externally connected to a steam supply system, and the other group of conveying pipe groups is externally connected to an air supply system;

[0008] Each group of conveying pipe groups includes a main conveying pipe arranged outside the drying box. Along the steam inlet direction, an inlet steam pump and an inlet steam valve are successively arranged on the main conveying pipe connected to the steam supply system. Along the air inlet direction, an inlet air pump and an inlet air valve are successively arranged on the main conveying pipe connected to the air supply system. The flow rates of steam and air are adjusted according to different drying requirements through the pumps and valves to adapt to the characteristics of different batches of morel mushrooms.

[0009] A number of conveying branch pipes are successively arranged on the main conveying pipe along the length direction. Each conveying branch pipe extends into the drying box and is vertically arranged along the inner wall of the drying box. At the tops of several conveying branch pipes on the same side, a connecting longitudinal pipe is provided. Several connecting cross pipes are arranged between the two groups of connecting longitudinal pipes.

[0010] The first air outlet nozzles are uniformly arranged along the length direction of the conveying branch pipes, and the first air outlet nozzles are arranged with their openings facing downward. The second air outlet nozzles are uniformly arranged along the length direction of the connecting cross pipes, and the second air outlet nozzles are arranged with their openings facing horizontally. The media sprayed by the first air outlet nozzles and the second air outlet nozzles are not directed at the mushroom bodies, so as not to cause damage to the mushroom bodies due to excessive pressure. The uniform drying process helps to maintain the nutritional components and flavor of the morel mushrooms and improve the market competitiveness of the products.

[0011] As a further solution of the present utility model, an inlet and an outlet are respectively arranged at both ends of the drying box. Two mutually parallel guide rails are arranged in the drying box along the direction from the inlet to the outlet. A multi-layer bracket for loading morel mushrooms is slidably matched with the guide rails. The guide rails provide a stable support platform, ensuring that the multi-layer bracket is not easily tilted or moved during the drying process, enabling the multi-layer bracket to smoothly enter and exit the drying box, simplifying the loading and unloading processes, and improving work efficiency. And it allows the multi-layer brackets to be stacked in the vertical direction, effectively utilizing the internal space of the drying box and increasing the number of morel mushrooms that can be processed.

[0012] As a further solution of the present utility model, the multi-layer bracket includes a bracket bottom plate. Two rows of guide rail wheels are arranged at the bottom of the bracket bottom plate along the length direction. Brake pads are arranged on the guide rail wheels.

A number of horizontally arranged placement plates are arranged on the plurality of columns along the vertical direction. A plurality of ventilation holes are densely arranged on each placement plate. The multi-layer bracket realizes layered placement in a limited space, greatly improving the space utilization rate for storing morel mushrooms. A plurality of ventilation holes are densely arranged on each placement plate, which can promote air circulation, ensure that the hot air is evenly transmitted to each layer of morel mushrooms, and improve the drying effect.

[0013] As a further solution of the present utility model, the dehumidification component includes a dehumidification pipe orifice provided at the upper part of the drying box body. A dehumidification pipe is provided on the dehumidification pipe orifice, and a dehumidification valve and a vacuum pump are provided on the dehumidification pipe. The humidity change during the drying process can be flexibly controlled according to actual needs. The opening and closing of the dehumidification valve can be accurately adjusted. The use of the vacuum pump can quickly reduce the air pressure in the box, thereby accelerating the evaporation of moisture, ensuring the best drying effect, and improving the drying efficiency.

[0014] As a further solution of the present utility model, the liquid discharge component includes an inclined groove on the bottom plate of the drying box body that slopes towards the central axis. Several liquid discharge ports are provided at the bottom of the inclined groove, a liquid discharge elbow is provided at the liquid discharge port, a horizontal liquid discharge pipe is provided at the free end of the liquid discharge elbow, and a liquid discharge pump is provided thereon. The inclined inclined groove enables the liquid in the drying box to naturally flow to the bottom of the groove, ensuring high drainage efficiency and avoiding water accumulation. Multiple liquid discharge ports can quickly discharge a large amount of liquid, improve the liquid discharge speed, and help maintain a good working environment.

[0015] As a further solution of the present utility model, supports are provided on both sides of the bottom of the drying box along the length direction of the box body. An opening is provided on the side wall of one of the supports, and the horizontal liquid discharge pipe extends out along the opening. The height of the support is higher than the horizontal height of the horizontal liquid discharge pipe. The supports are arranged along the length direction of the box body, which can effectively disperse the weight of the drying box. The opening design on the side wall of the support enables the horizontal liquid discharge pipe to extend out smoothly, forming a natural gravity flow, reducing the resistance during the liquid discharge process, and improving the drainage efficiency.

[0016] As a further solution of the present utility model, a number of U-shaped bolts are evenly distributed along the length direction of the connecting horizontal pipe. Each U-shaped bolt is arranged between two adjacent horizontal air outlet nozzles, and the two free ends of the U-shaped bolt are fixed on the top wall of the drying box;

[0035] As Figures 1 to 5 shown, a morel drying device includes a drying box 1. The two ends of the drying box are respectively provided with an inlet and an outlet. At the inlet and outlet of the drying box, there are mutually cooperating door frames 104 and door panels 102. On one side of the door frame and the door panel, there is a hinge 101, and on the other side, there is a locking member 103. The hinge includes a first hinge plate and a second hinge plate. The first hinge plate is fixedly arranged on the side of the door frame, and the second hinge plate is fixedly arranged on the door panel. Both the first hinge plate and the second hinge plate are provided with hinge holes, and a hinge shaft is arranged in the hinge holes. The door panel rotates along the hinge shaft to open or close.

[0036] In the non - use state, the doors at the inlet and outlet are both open. The drying box is provided with two mutually parallel guide rails 105 along the direction from the inlet to the outlet. The multi - layer bracket 8 for loading morels is slidably engaged with the guide rails. There is a movable multi - layer bracket inside the drying box. After loading the multi - layer bracket, before sending the multi - layer bracket into the drying box, rotate the door panel on the outlet side along the hinge shaft. There is a sealing groove on the door frame, and a sealing ring is arranged in the sealing groove. The sealing ring is a trapezoidal rubber sealing strip, which seals and cooperates the door panel and the door frame, and is locked and closed through the locking member.

[0037] The multi - layer bracket includes a bracket bottom plate. Along the length direction at the bottom of the bracket bottom plate, there are two rows of guide wheels 803. Brake pads are arranged on the guide wheels. Each row of guide wheels is slidably engaged with the corresponding side guide rail. Along the circumferential direction on the bracket bottom plate, there are multiple vertical columns 802. Along the vertical direction, there are several layers of horizontally arranged placing plates 801 on the multiple columns. Air - vent holes 811 are densely arranged on each layer of placing plate. The morels are transferred to each layer of the placing plate of the multi - layer bracket manually or by mechanical equipment, and are laid evenly. Air - vent holes are densely arranged on each layer of the placing plate, and air or steam is evenly transmitted to each layer of morels through the air - vent holes for drying.

[0038] An inclined gradient support plate is erected on the inlet side of the drying box. The multi - layer bracket slides into the drying box along the gradient support plate and enters the drying box along the guide rail. When the multi - layer bracket moves to the set position of the guide rail, start the brake pads to fix the multi - layer bracket in the drying box.

[0039] The door panel at the inlet is rotated and sealed with the door frame, and locked and closed through the locking member. A sealed drying space is formed inside the drying box.

[0040] On the side and top of the multi-layer bracket, a drying component 3 for alternately supplying steam and cold air is provided on the inner wall of the corresponding drying box. The drying component includes two groups of conveying pipe groups. One group of conveying pipe groups is externally connected to a steam supply system, and the other group of conveying pipe groups is externally connected to an air supply system;

[0041] Each group of conveying pipe groups includes a main conveying pipe 301 arranged outside the drying box. Along the steam inlet direction, a steam inlet pump 311 and a steam inlet valve 312 are successively arranged on the main conveying pipe connected to the steam supply system. Along the air inlet direction, an air inlet pump 3511 and an air inlet valve 305 are successively arranged on the main conveying pipe connected to the air supply system.

[0042] Four conveying branch pipes 302 are successively arranged along the length direction of the main conveying pipe. Each conveying branch pipe extends into the drying box and is vertically arranged along the inner wall of the drying box. A number of reinforcing cross ribs 322 are evenly arranged along the length direction of the two groups of conveying branch pipes. The other ends of the reinforcing cross ribs are fixed on the inner wall of the drying box body.

[0043] At the tops of several conveying branch pipes on the same side, a connecting vertical pipe 304 is provided. Between the two groups of connecting vertical pipes, a number of connecting horizontal pipes 303 are provided; a number of U-shaped bolts 332 are evenly arranged along the length direction of the connecting horizontal pipe. Each U-shaped bolt is arranged between two adjacent horizontal air outlet nozzles. The two free ends of the U-shaped bolt are fixed on the top wall of the drying box;

[0044] At the beginning, first open the steam inlet pump 311 and the steam inlet valve 312, and at the same time close the air inlet pump and the air inlet valve.

[0045] The steam in the steam supply system, with a temperature between 40°C and 70°C, is conveyed along the main conveying pipe to each conveying branch pipe 302. The first air outlet nozzles 321 are evenly arranged along the length direction of the conveying branch pipe. The first air outlet nozzles are arranged with their openings facing downwards and spray through the first air outlet nozzles.

[0046] At the tops of four conveying branch pipes on the same side, a connecting vertical pipe 304 is provided. The steam continues to flow upwards along the conveying branch pipe. There are four connecting horizontal pipes between the two groups of connecting vertical pipes. The connecting horizontal pipes are filled with steam. The second air outlet nozzles 331 are evenly arranged along the length direction of the connecting horizontal pipe. The second air outlet nozzles are arranged with their openings facing horizontally. The steam sprays out through the second air outlet nozzles. The media sprayed out by the first air outlet nozzles are not aligned with the bacteria bodies and will not cause damage to the mushroom bodies due to excessive pressure.

[0047] A dehumidification component 4 is provided at the upper part of the drying oven. The dehumidification component discharges the humidity in the drying oven in a timely manner. The dehumidification component includes a dehumidification pipe orifice provided at the upper part of the drying oven body. A dehumidification pipe is provided on the dehumidification pipe orifice. A dehumidification valve 401 and a vacuum pump 402 are provided on the dehumidification pipe. The change of humidity during the drying process can be flexibly controlled according to actual needs. The dehumidification valve is opened and closed, and the vacuum pump is started to quickly reduce the air pressure in the oven, accelerating the evaporation of moisture in the drying oven.

[0048] During the process of drying with steam filling the drying oven, a liquid drainage component 6 is provided at the bottom of the drying oven. The liquid drainage component includes an inclined groove on the bottom plate of the drying oven body that slopes towards the central axis. Several liquid drainage orifices are provided at the bottom of the inclined groove. A liquid drainage elbow is provided at the liquid drainage orifice. A horizontal liquid drainage pipe is provided at the free end of the liquid drainage elbow, and a liquid drainage pump 601 is provided on it. The water vapor condenses to form liquid water, and the inclined inclined groove enables the liquid in the drying oven to naturally flow towards the bottom of the groove.

[0049] Two supports 2 are provided on both sides of the bottom of the drying oven along the length direction of the oven body. An opening is provided on the side wall of one of the supports. The horizontal liquid drainage pipe extends out along the opening, and the height of the support is higher than the horizontal height of the horizontal liquid drainage pipe. The condensed water flows by natural gravity. The liquid drainage pump is opened to drive the collected condensed water to be discharged along the horizontal liquid drainage pipe.

[0050] After steam drying, the surface of the mushroom body is relatively moist. Then, the air inlet pump 3511 and the air inlet valve 305 are opened, and the steam inlet pump and the steam inlet valve are closed, and the air supply system is started.

[0051] The high-pressure cold air in the air supply system is transported along the main transport pipe to each transport branch pipe 302 and sprayed out through the first air outlet nozzle. The cold air continues to flow upward along the steam along the transport branch pipe and is further transported into the connecting horizontal pipe. The connecting horizontal pipe is filled with cold air, and the cold air is sprayed out through the second air outlet nozzle. The medium sprayed out by the second air outlet nozzle is not aligned with the mushroom body, and it will not cause damage to the mushroom body due to excessive pressure, and the mushroom body is finally dried.

[0052] During the process of drying with cold air filling the drying oven, the moisture on the mushroom body falls downward into the inclined groove for collection. After flowing by gravity, the liquid drainage pump is opened to drive the collected liquid to be discharged along the horizontal liquid drainage pipe.

[0053] A thermometer orifice, a pressure gauge orifice and a pressure relief orifice are provided at the top of the drying oven. A thermometer 9 is provided at the thermometer orifice, a pressure gauge 7 is provided at the pressure gauge orifice, and a pressure relief valve 5 is provided at the pressure relief orifice. The settings of the thermometer and the pressure gauge can monitor the internal temperature and pressure in real time to ensure that the equipment operates within a safe and efficient working range.

[0054] During the entire drying state, the operator monitors the pressure in real time. When the pressure is too high, the pressure relief valve is opened to effectively release the excessive pressure, and the progress of the drying process is adjusted through the real-time feedback of the thermometer.

[0055] After the drying is completed, first open the pressure relief valve 5 to release the pressure in the drying box. When the pressure in the drying box is zero, unlock the locking member 103 at the outlet, and drive the door panel to rotate relative to the hinge axis, and the door panel opens relative to the door frame.

[0056] The drying box is provided with two parallel guide rails 105 along the inlet to the outlet direction, and the multi-layer bracket for loading morel mushrooms is slidably matched with the guide rails. A movable multi-layer bracket 8 is provided in the drying box. After loading the multi-layer bracket, before the multi-layer bracket is sent into the drying box, rotate the door panel on the outlet side through the hinge axis. A sealing groove 141 is provided on the door frame 104, and a sealing ring is provided in the sealing groove. The sealing ring is a trapezoidal rubber sealing strip 1, and the door panel and the door frame are hermetically fitted and locked and closed through the locking member.

[0057] An inclined slope support plate is erected on the outlet side of the drying box. Loosen the brake pads, and the multi-layer bracket 8 slides along the guide rail 105 and is transferred from the slope support plate to the outside of the drying box to complete the drying, cooling and transfer of the morel mushrooms.

[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0059] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
