Description

Technical Field

[0001] This utility model relates to the field of edible fungi processing technology, and in particular to an air-source heat pump dryer for drying edible fungi. Background Technology

[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. China has nearly 950 known species of edible fungi, including: shiitake mushrooms, straw mushrooms, button mushrooms, wood ear mushrooms, silver ear mushrooms, monkey head mushrooms, bamboo fungus, matsutake mushrooms, button mushrooms, red mushrooms, reishi mushrooms, cordyceps, truffles, white lingzhi mushrooms, and porcini mushrooms, among others.

[0003] In the prior art, a search revealed a Chinese patent disclosing "An Air-Source Heat Pump Dryer for Edible Fungus Drying," application number "202022284374.4." This patent mainly includes a drying shell, with a support fixedly connected to the bottom of the shell, a drying pipe fixedly connected to the top wall, an external exhaust pipe fixedly connected to the bottom wall, a motor fixedly mounted on the right outer wall, a clamping plate fixedly connected to the motor's output shaft, auxiliary frames fixedly connected to the inner walls of the left and right sides, auxiliary rolling balls movably connected to the inner walls of the auxiliary frames, and a cover movably connected to the left side of the shell. While this air-source heat pump dryer for edible fungus has a good overall structure and facilitates uniform drying of edible fungus, and is convenient to operate and environmentally friendly, effectively solving the problems of high pollution and difficulty in uniform drying associated with traditional methods, the use of rotating drying racks means that the edible fungus's structure is relatively fragile and easily damaged before drying. When edible fungi are dried using a rolling method, they constantly tumble and collide within the drying rack, easily causing surface damage or even breakage, thus affecting their integrity and quality. Therefore, this invention provides an air-source heat pump dryer for drying edible fungi to solve the problems mentioned in the background section. Utility Model Content

[0026] Reference Figure 1-4 This utility model discloses an air-source heat pump dryer for drying edible fungi, comprising a drying chamber 1 with a door 19 installed on the front side. Multiple U-shaped movable frames 2 are equidistantly arranged inside the drying chamber 1, each with one end rotatably connected to the inner wall of the drying chamber 1. U-shaped support frames 3 are fixedly connected to the inner side of each movable frame 2. A feeding plate 4 is provided above the support frame 3, and the feeding plate 4 is designed with a hollow structure to allow hot air to pass through evenly, improving drying efficiency. Multiple limiting blocks 5 are symmetrically fixedly connected to the outer side of each feeding plate 4 at equal intervals. Each movable frame 2 has a limiting groove 6 that engages with the limiting blocks 5, ensuring stable positioning of the feeding plate 4 during placement and removal. A connecting plate 7 is rotatably connected between every two adjacent movable frames 2. Two connecting rods 8 are symmetrically rotatably connected to the top side of the uppermost movable frame 2. A control component for driving the connecting rods 8 to move up and down is provided on the top of the drying chamber 1. The control component includes an electric push rod 10 fixedly connected to the top of the drying chamber 1 and an end plate 9 fixedly connected to the top of the piston rod of the electric push rod 10. The top of the connecting rods 8 passes through the top side of the drying chamber 1 and is rotatably connected to the end plate 9. A sealing sleeve is fixedly connected to the top side of the drying chamber 1 at the point where the connecting rods 8 pass through. A good mechanical seal structure is used to form a sealing sleeve, which can ensure the airtightness of the drying chamber 1.

[0027] The support frame 3 on the movable rack 2 supports the feeding plate 4. The feeding plate 4 is movable, making it easy to remove and place the edible fungi to be dried on it. Placing the feeding plate 4 back on the support frame 3, with each layer spaced apart, ensures uniform hot air circulation for the edible fungi during drying, guaranteeing their integrity and quality. After drying, the electric push rod 10 controls the downward movement of the end plate 9 and its connecting rod 8. Connected by the connecting plate 7, each layer of the movable rack 2 moves around its rotating connection with the drying chamber 1, allowing the feeding plate 4 to tilt downwards. A collection box is placed at the discharge port of the feeding plate 4. The tilted feeding plate 4 allows the dried edible fungi to be discharged into the collection box for collection, improving the dryer's ease of operation and efficiency, making it highly practical.

[0028] A main air duct 11 is fixedly connected to one side of the drying chamber 1 near the bottom. A branch air duct 12 located below the feeding plate 4 is fixedly connected to one side of the main air duct 11. There are multiple branch air ducts 12, which are evenly fixedly connected to the main air duct 11. Each branch air duct 12 has an air outlet 13 fixedly connected to its top side to ensure that hot air can be evenly blown onto the edible fungi on the feeding plate 4, so that the hot air is evenly distributed and the drying is not uneven.

[0029] To provide hot air, an air heat pump 16 is installed on one side of the drying chamber 1. A blower 17 is installed between the air heat pump 16 and the drying chamber 1, and the blower 17 and the air heat pump 16 are connected by a pipe. An air supply main pipe 11 is connected to the blower 17, and the blower 17 delivers the hot air generated by the air heat pump 16 into the air supply main pipe 11. An exhaust fan 14 is fixedly connected to the top of the drying chamber 1, and an exhaust pipe 15 is fixedly connected to the top side of the drying chamber 1. The exhaust pipe 15 is connected to the exhaust fan 14 and is used to exhaust the moisture in the drying chamber 1. A temperature and humidity sensor 20 is fixedly connected to the inner wall of the drying chamber 1, and a controller 18 is also installed on one side of the drying chamber 1 for convenient monitoring and control of the temperature and humidity in the drying chamber 1.

[0030] To improve the heat preservation performance of the dryer, the outer sides of the drying chamber 1 and the door 19 are fixedly connected with a heat preservation layer, which is a polyurethane board and has a good heat preservation effect.

[0031] Working Principle: The support frame 3 on the movable frame 2 supports the feeding plate 4. The feeding plate 4 is movable, making it easy to remove and place the edible fungi to be dried onto it. The feeding plate 4 is then placed back on the support frame 3. The spacing between each layer ensures uniform hot air circulation for the edible fungi during drying, guaranteeing their integrity and quality. After drying, the electric push rod 10 controls the downward movement of the end plate 9 and its connecting rod 8. Connected by the connecting plate 7, each layer of the movable frame 2 moves around its rotating connection with the drying chamber 1, allowing the feeding plate 4 to tilt downwards. A collection box is placed at the discharge port of the feeding plate 4. The tilted feeding plate 4 allows the dried edible fungi to be discharged into the collection box for collection, improving the dryer's ease of operation and efficiency, making it highly practical.
