[0002] Shiitake mushrooms are an agricultural product. As a common edible fungus, shiitake mushrooms have a delicious taste, unique aroma, and are rich in nutrients, including various vitamins, minerals, and shiitake polysaccharides. They have the effects of improving immunity and anti-tumor properties. Shiitake mushroom drying is an important step in the processing of shiitake mushrooms. Dried shiitake mushrooms are easy to store and transport, and can be preserved for a long time and sold in the market.

[0003] The existing drying equipment for agricultural product processing still has the following shortcomings: the existing drying equipment for agricultural product processing lacks the function of waste heat recovery. During drying, a large amount of hot air is discharged along with the moisture, which wastes the heat energy contained therein, resulting in a sharp increase in energy consumption. At the same time, the discharged high-temperature gas increases thermal pollution, raises the temperature in the processing workshop, and deteriorates the working environment for workers. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a drying device for agricultural product processing with a waste heat recovery mechanism, which solves the problem that existing drying devices for agricultural product processing lack waste heat recovery function.

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution:

[0021] A drying device for agricultural product processing with a waste heat recovery mechanism includes a housing 1, a door 2 on one side of the housing 1, a servo motor 3 fixedly connected to the bottom of the housing 1, the output end of the servo motor 3 passing through the housing 1 and rotatably connected thereto, a turntable 4 fixedly connected coaxially to the output end of the servo motor 3, a placement rack 5 fixedly connected to the top of the turntable 4, multiple placement plates 6 arranged on the placement rack 5, an air outlet duct 7 connected to the top of the housing 1, a heat recovery component arranged at the top of the air outlet duct 7, heaters 8 arranged on both sides of the housing 1, preheating components arranged on the heaters 8, mushrooms placed on the placement plates 6, the heaters 8 are activated, and external heat is released. Air enters heater 8, which sends the heated air into chamber 1. Servo motor 3 is started, and the output of servo motor 3 drives turntable 4 to rotate slowly. Turntable 4 drives the placement plate 6 to rotate together through placement rack 5, which allows the shiitake mushrooms to be blown by hot air in all directions and evenly during the drying process. This avoids the situation where some shiitake mushrooms are over-dried or under-dried due to uneven heating in some areas, thus ensuring the drying quality. The hot air carrying moisture enters the recovery component through the air outlet duct 7 at the top of chamber 1. The recovery component can absorb the heat in the hot air, and the preheating component can use the recovered heat to preheat the outside air entering heater 8.

[0022] The recycling component includes a drying tank 9, which is connected to the top of the air outlet duct 7. A heat dissipation pipe 10 is connected to the top of the drying tank 9, and a water tank 11 is fixedly connected to the heat dissipation pipe 10. Hot air carrying water vapor passes through the drying tank 9 and the heat dissipation pipe 10 in sequence. The drying tank 9 contains a desiccant that can absorb water vapor. The heat dissipation pipe 10 is partially bent so that the heat in the hot air is transferred to the water in the water tank 11 through the heat dissipation pipe 10.

[0023] The preheating assembly includes an air inlet duct 12 and a water pump 13. The air inlet duct 12 is connected to one side of the heater 8, and the water pump 13 is fixedly connected to the top of the heater 8. An inlet 14 and an outlet 15 are connected to the air inlet duct 12. An outlet pipe 16 is connected to the outlet 15, with one end of the outlet pipe 16 connected to a water tank 11. An inlet pipe 17 is connected to the input end of the water pump 13, with one end of the inlet pipe 17 connected to the water tank 11. An inlet pipe 18 is connected to the output end of the water pump 13, with one end of the inlet pipe 18 connected to the inlet 14. Outside air passes through the air inlet duct 12. 2. The water enters the heater 8. A cavity is opened in the air inlet pipe 12. Multiple horizontal pipes are installed in the air inlet pipe 12. Both ends of the horizontal pipes are connected to the cavity of the air inlet pipe 12. The water pump 13 is started. The hot water in the water tank 11 enters the water pump 13 through the water inlet pipe 17. Then, the water pump 13 outputs through the water inlet pipe 18 into the water inlet 14. The hot water enters the cavity of the air inlet pipe 12 through the water inlet 14. The hot water exchanges heat with the outside air through the inner wall of the air inlet pipe 12 and the horizontal pipes. The water in the air inlet pipe 12 can flow back to the water tank 11 through the water outlet 15 and the water inlet pipe 17 to replenish the heat.

[0024] A filter 19 is installed at one end of the air inlet duct 12, which can filter dust and impurities in the air.

[0025] A mesh 20 is provided on the top of the heat pipe 10 to prevent dust and impurities from falling into the heat pipe 10.

[0026] Two pairs of support columns are fixedly connected to the bottom of the box 1. The support columns are used to support and stabilize the box 1.

[0027] The working principle of this utility model is as follows:

[0028] The shiitake mushrooms are placed on the placement plate 6, and the heater 8 is turned on. Outside air enters the heater 8 through the air inlet pipe 12. The heater 8 sends the heated air into the chamber 1. The servo motor 3 is turned on, and the output of the servo motor 3 drives the turntable 4 to rotate slowly. The turntable 4 drives the placement plate 6 to rotate together through the placement rack 5. This allows the shiitake mushrooms to receive hot air in all directions and evenly during the drying process, avoiding the situation where some shiitake mushrooms are over-dried or under-dried due to uneven heating in some areas, thus ensuring the drying quality.

[0029] Hot air carrying moisture passes through the air outlet duct 7 at the top of the housing 1, then through the drying tank 9 and the heat dissipation pipe 10. The drying tank 9 contains a desiccant to absorb moisture. The heat dissipation pipe 10 is partially bent, allowing heat from the hot air to be transferred to the water in the water tank 11. The water pump 13 is then activated, and the hot water in the water tank 11 enters the water pump 13 through the inlet pipe 17. The hot water is then pumped from the output end of the water pump 13 through the inlet pipe 18 into the inlet 14. The hot water then enters the cavity of the air inlet duct 12 through the inlet 14. The hot water exchanges heat with the outside air through the inner wall and horizontal pipe of the air inlet duct 12, preheating the outside air entering the heater 8. The water in the air inlet duct 12 can flow back to the water tank 11 through the outlet 15 and the inlet pipe 17 to replenish the heat.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
