Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a drying device for convenient food processing. Background Technology

[0002] Convenience food processing requires dehydration to extend shelf life, such as dried fruit, dried meat, and dried vegetables. Drying or air drying are commonly used methods. Drying involves higher temperatures, which can damage food proteins and fibers; air drying is gentler on food, with lower temperatures, but it takes longer and requires longer conveyor belts to achieve automated air drying for convenience foods.

The air-drying box 1 has a feeding hopper 11 on one side of its upper end and a discharging hopper 12 on one side of its lower end. The conveying mechanism includes several sets of conveyors 2 vertically distributed inside the air-drying box 1. The conveyors 2 are chain plate 21 conveyors 2, and ventilation holes are distributed on the chain plate 21. The end of the upper conveyor 2 is located above the lower conveyor 2 to receive the material falling from the upper conveyor 2. The blower mechanism includes an air guide box 3 disposed on one side of the air-drying box 1 and an upper air pipe 31 and a lower air pipe 32 distributed and installed inside the air-drying box 1 to air-dry the food on the chain plate 21.

[0027] like Figure 2 As shown, in this embodiment, chains are provided on both sides of the conveyor 2. The chains are sleeved on the sprockets at both ends of the conveyor 2. The sprockets are fixedly installed on the rotating shaft and are connected to the servo motor 22 at the outer end of the drying box 1 through the rotating shaft. The chain plates 21 are rotatably connected to each other through pins and connected to the chain through pins to control the orderly movement of the chain plates 21.

[0028] The conveyor 2 has pedestals 23 distributed between the chain plates 21 on the upper and lower sides of the conveyor 2. The pedestals 23 are spaced apart and their upper and lower ends abut against the chain plates 21 to limit the chain plates 21. An air guide cavity 24 is formed between adjacent pedestals 23 to allow ventilation of the chain plates 21.

[0029] One side of each of the upper air duct 31 and lower air duct 32 is connected to the air guide box 3. The upper air ducts 31 are spaced apart and installed in the corresponding air guide chambers 24. The upper end of the upper air duct 31 is provided with an upper ventilation groove 33. The airflow from the upper ventilation groove 33 passes through the air guide chamber 24 and blows onto the chain plate 21, drying the food through the ventilation holes on the chain plate 21. The lower air ducts 32 are spaced apart and installed at the upper end of the conveyor 2. The lower end of the lower air duct 32 is provided with a lower ventilation groove 34. The airflow from the lower ventilation groove 34 dries the food on the chain plate 21. The upper air ducts 31 and lower air ducts 32 are staggered to avoid the upper and lower airflows from clashing and to improve the drying effect on the food.

[0030] like Figure 3 As shown in this embodiment, the outer end of the air guide box 3 is provided with an air guide pipe 35, and the air guide pipe 35 is connected to the fan through an external pipe. Heating pipes 36 are distributed inside the air guide box 3 to increase the temperature as needed.

[0031] like Figure 2 As shown, in this embodiment, the end of the conveyor 2 is provided with a guide slide 13 to guide the falling food, so as to guide the food to the chain plate 21 and ensure that the food is connected in an orderly manner between the conveyors 2.

[0032] like Figure 3 As shown, in this embodiment, the lower end of the conveyor 2 is also provided with a collecting plate 14 for receiving powder and slag. The collecting plate 14 is inclinedly arranged in the drying box 1. Multiple sets of collecting plates 14 are provided corresponding to the conveyor 2. The drying box 1 is provided with a collecting hole 15 on one side of the lower end of the collecting plate 14. The outer end of the drying box 1 is provided with a collecting box 16 to discharge the dust and airflow concentrated in the collecting hole 15 to the outside.

[0033] Specifically, personnel feed the food to be dried from the feed hopper 11 onto the conveyor 2 at the top of the drying box 1. The vertically arranged conveyors 2 are then connected in an orderly manner to extend the drying conveyor line and reduce the size of the equipment. The air guide box 3 directs airflow to the corresponding conveyor 2 through the distributed upper air pipes 31 and lower air pipes 32 to dry the food on the chain plate 21. The upper air pipes 31 and lower air pipes 32 are spaced apart to improve the drying effect. The hot and humid airflow is introduced into the collection box 16 on one side through the collection hole 15, and the dust falling off the chain plate 21 during conveying is collected by the collection plate. This device has a compact structure, good drying effect, and can greatly reduce drying time and improve food drying efficiency.
