Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a mesh belt drying mechanism for a fluidized bed quick-freezing device. Background Technology

[0002] In the process of fluidized bed quick-freezing, the product usually needs to be pre-cleaned to remove impurities from the product surface. Since the product surface still contains moisture after cleaning, if the cleaned product is directly put into the quick-freezing device for surface freezing, the final quick-frozen product will stick together, affecting a series of subsequent operations and resulting in poor quick-freezing effect.

[0003] Existing drying mechanisms typically only have an upward or downward air supply structure. They dry the products on the conveyor belt by installing downward or upward air inlet pipes at the top of the drying chamber. This structure cannot provide uniform air supply to the upper and lower parts of the products, resulting in uneven drying effects. Utility Model Content

[0017] A mesh belt drying mechanism for a fluidized bed quick-freezing device, such as Figure 1 As shown, the system includes a vibrating screen 1 connected to a conveyor belt, a drying box 3 located on the right side of the discharge end of the vibrating screen 1, and a control cabinet. The vibrating screen 1 can initially remove residual moisture from the surface of the product. A water collection tank 2 is provided below the vibrating screen 1, which can collect the water that falls off when the vibrating screen 1 drives the product to vibrate.

[0018] The control cabinet is equipped with a PLC controller. The output terminals of the PLC controller are connected to the controlled terminals of the vibrating screen 1 and the drying box 3 respectively. The control cabinet is not shown in the figure. The internal structure and circuit connection method of the control cabinet are based on the industry's common design standards. The control cabinet adopts a standardized frame structure, and each functional unit is arranged according to the established specifications. The circuit connection follows the standard electrical connection specifications and uses mature connectors and terminals to ensure the reliability and stability of the circuit connection.

[0019] Vibrating screen 1 is connected to a vibrator, which is driven by a vibrating motor. The output terminal of the controlled PLC controller of the vibrating motor is connected to the vibrating screen 1.

[0020] A conveyor belt 4 is installed below the discharge end of the vibrating screen 1. The conveyor belt 4 passes through the drying box 3. The surface of the conveyor belt 4 is provided with a breathable mesh to facilitate the hot air in the drying box 3 to blow through and dry the surface moisture of the product on the conveyor belt 4.

[0021] The two ends of the conveyor belt 4 are connected to the drive shafts respectively. One of the drive shafts is driven by a rotary motor, and the controlled end of the rotary motor is connected to the output end of the PLC controller.

[0022] The left side wall of the drying chamber 3, located above the conveyor belt 4, is provided with an inlet 5 for the products on the conveyor belt 4 to pass through, and the right side wall of the drying chamber 3, located above the conveyor belt 4, is provided with an outlet 6 for the products on the conveyor belt 4 to pass through.

[0023] The upper part of the drying oven 3 is provided with an upper air inlet pipe 7 and a lower air inlet pipe 8 for intermittent air intake. The upper air inlet pipe 7 and the lower air inlet pipe 8 are respectively connected to the hot air box. The hot air box is a conventional structure known to those skilled in the art and can be obtained by purchasing existing products. It is not shown in the figure.

[0024] The upper air inlet duct 7 is installed on the left side wall of the drying chamber 3, which can dry the product surface from top to bottom. The lower air inlet duct 8 is installed on the right side wall of the drying chamber 3, which can dry the product surface from bottom to top.

[0028] In use, the cleaned product is conveyed to the vibrating screen 1 via a conveyor belt. The vibrating screen removes the moisture from the product surface. The water that falls off is collected in the water collection tank. The product that has been partially dehydrated is then conveyed to the conveyor belt 4 and conveyed to the drying oven 3 via the conveyor bag 4 for drying.

[0029] During drying, air is intermittently supplied to the drying chamber 3 through the upper air inlet pipe 7 and the lower air inlet pipe 8. That is, air is first supplied from top to bottom to dry the products on the conveyor belt. After the electronic timer on the upper air inlet pipe ends, air is supplied from bottom to top to dry the products. This process is repeated several times. After the products are dried, the air supply is stopped, and the dried products are sent out through the conveyor belt.
