KJG series hollow blade dryer is a kind of high efficiency and energy saving indirect conduction drying equipment, mainly through the heating medium in the hollow blade and shell jacket flow, heat conduction drying of materials. Its working principle, equipment structure and advantages are as follows:

First, KJG series hollow blade dryer working principle

The hollow blade dryer uses the principle of heat conduction to dry. The material enters the device through the feed port, and the hollow blade stirs the material to continuously turn over and renew the heated surface. A hot medium (such as steam or thermal oil) flows through the blades and jacket, transferring heat to the material and evaporating water. The evaporated water is discharged through a vacuum or tail gas treatment device, and the material is finally dried.

Second, KJG series hollow blade dryer equipment structure

1. ** Blade shaft ** : The core part of the equipment, the shaft is equipped with a plurality of hollow blades, stirring through rotation.

2. ** Jacket ** : used to transfer heat medium, improve heating efficiency.

3. ** Shell ** : closed container to ensure the material and heating medium isolation.

4. ** Feed port and discharge port ** : used respectively for feeding and discharging dried materials.

5. ** Drive device ** : Provide power to drive blade shaft rotation.

6. ** Exhaust gas treatment system ** : Remove water vapor and other gases.

Third, KJG series hollow blade dryer equipment advantages

1. ** High thermal efficiency ** : hollow blade dryer uses conduction heating, high heat transfer efficiency between material and heat source, high energy utilization rate.

2. ** Small footprint ** : Compact equipment design, suitable for limited space sites.

3. Wide adaptability ** * : Can handle a variety of types of materials, including viscous, slurry, powder and other materials.

4. ** Low energy consumption ** : Because the material is dried at low speed and constant temperature, the overall energy consumption is low.

5. ** Less material loss ** : closed operation, reduce the volatilization and loss of materials, maintain the quality of materials.

4, KJG series hollow blade dryer application range

1. ** Chemical industry ** : such as sludge treatment, aluminum hydroxide, calcium carbonate, etc.

2. ** Food industry ** : such as starch, grains, plant extracts, etc.

3. ** Pharmaceutical industry ** : such as drug intermediates, drug residue drying.

4. ** Environmental protection field ** : such as industrial wastewater treatment, sludge drying, etc.

The KJG series hollow blade dryer manufactured by Jiangsu Bohong Drying Company is widely used in various processes requiring low energy consumption and high efficiency drying because of its efficient heat transfer performance and multi-functional application scenarios.

KJG系列空心桨叶干燥机是一种高效节能的间接传导式干燥设备，主要通过加热介质在空心的桨叶和壳体夹套内流动，对物料进行热传导干燥。其工作原理、设备结构和优势如下：

一、KJG系列空心桨叶干燥机工作原理

空心桨叶干燥机利用热传导原理进行干燥。物料通过加料口进入设备，空心的桨叶搅拌物料，使其不断翻转、更新受热表面。热介质（如蒸汽或导热油）在桨叶和夹套中流动，将热量传递到物料上，使水分蒸发。蒸发的水分通过真空或尾气处理装置排出，*终实现物料的干燥。

二、KJG系列空心桨叶干燥机设备结构组成

1. **桨叶轴**：设备的核心部分，轴上装有多个中空的桨叶，通过旋转进行搅拌。

2. **夹套**：用于传递热介质，提升加热效率。

3. **壳体**：密闭容器，确保物料与加热介质隔离。

4. **加料口和出料口**：分别用于进料和排出干燥后的物料。

5. **驱动装置**：提供动力带动桨叶轴旋转。

6. **尾气处理系统**：排除水蒸气和其他气体。

三、KJG系列空心桨叶干燥机设备优势

1. **热效率高**：空心桨叶干燥机利用传导加热，物料与热源之间传热效率高，能量利用率高。

2. **占地面积小**：设备设计紧凑，适用于空间有限的场地。

3. **适应性广**：能够处理多种类型的物料，包括粘稠、浆状、粉状等物料。

4. **低能耗**：由于物料在低速、恒温下干燥，整体能耗较低。

5. **物料损失少**：密闭操作，减少了物料的挥发和损失，保持了物料的品质。
