Basic dimensions of tunnel dryer:

Is the length less than 50m and the width generally not exceeding 3.5? The inclination of the length direction of the m tunnel is 1/200

The length of the drying car is generally 2m, and the width is generally not more than 1.5m?

The thickness of the baking material layer is 20-30mm, and the distance between layers is over 100mm. The specific size depends on the material.

The running speed of the drying car depends on the final moisture content of the material.

The size and quantity of circulating fans should be determined according to specific measures

Introduction to Tunnel Drying Machine:

Place the dried materials in the trolley, on the conveyor belt, on the shelf, or freely stack them on the transportation equipment. The material moves forward along the channel in the drying chamber and is discharged from the other end. For most of the leaf, fiber, and block materials with high moisture content, high yield, and low added value, the tunnel dryer is an economical and practical drying equipment.

It can be composed of metal materials such as bricks, cement, or insulation layers.

The longer and more uniform the dry tunnel, the greater the resistance.

Hot air from tunnel dryers: hot air from coal-fired hot air furnaces, hot air generated from natural gas, coal gas, and oil fired hot air furnaces, hot air generated from electric heating elements and steam, hot air generated from thermal oil furnaces, and waste heat from flue gas can also be utilized.

The tunnel can enter from the upper or lower part of one end, exit from the other end can enter from both ends, and exit from the middle (this method has low resistance and high thermal efficiency) can also be recycled in multiple sections. Further improving thermal efficiency and achieving uniform and rapid drying can be done in parallel or in reverse, depending on the properties of the material.

The entry and exit of the drying car can be carried out by tracks, electric reducers, or manually.

The drying car can have a metal cabinet frame structure, and the drying tray can be made of metal mesh or stainless steel mesh, as well as wooden strips, bamboo mesh, sieves, etc.

The DC circulating drying tunnel is an improved technology introduced from Russia's PY type drying chamber. When the material has a high moisture content, it can be set as a DC drying chamber. When the material is close to drying, it can be set as a circulating drying chamber. Not only does the dried material have a good color, but it also greatly reduces production costs for users.

The drying room is equipped with our factory's developed product - S-shaped flow control plate (which can make the material heated more evenly), and high-temperature dust removal filter (which can filter out all external dust and ensure that the dried product meets the export requirements). Our factory's aim is to provide every customer with information on seafood drying technology.

  & nbsp; Suitable for drying operations of fish, shrimp, shellfish, seaweed, and agricultural and sideline products.

  & nbsp; Heating methods: combustible coal, fuel oil, gas, and electric heating.

  & nbsp; The size of the drying room can be designed and manufactured according to user requirements and production capacity.
