The screw squeeze dryer is a dehydration equipment widely used in the industrial field. It places the material in a rotating spiral cylinder and uses the action of mechanical extrusion to quickly remove the moisture in the material, thereby achieving the purpose of dehydration. Screw squeeze dryers are widely used in food processing, chemical industry, agriculture, environmental protection and other fields, and can handle various types of materials. This article will explore the application and advantages of screw squeeze dryers in the dehydration treatment of various materials.

1. Working principle of screw squeeze dryer

The working principle of the screw squeeze dryer is based on the extrusion and separation process of materials in the rotating screw barrel. Specifically, the screw squeeze dryer includes a spiral barrel. The material enters through the feed port, and then through the rotation of the spiral barrel, the material is gradually squeezed in the barrel, the moisture is quickly separated, and finally discharged through the drain port. , and the dry material is discharged through the discharge port.

The working principle of the screw squeeze dryer makes it suitable for a variety of different types of materials, including but not limited to:

1. Food materials: The moisture in food materials such as vegetables, fruits, and meats can be quickly removed by a screw squeeze dryer, thereby extending the shelf life of food and reducing food waste.

2. Chemical raw materials: Powder and granular materials in the chemical industry can reduce the moisture content through a screw squeeze dryer and improve the stability and quality of the product.

3. Agricultural waste: Agricultural waste such as straw, feed residue, etc. can be dehydrated through a screw squeeze dryer to reduce the volume of waste and facilitate subsequent processing and utilization.

4. Environmental protection field: Sludge dehydration in sludge and wastewater treatment is also a common application of screw squeeze dryers, which can reduce the cost of wastewater treatment and environmental pollution.

2. Advantages of screw squeeze dryer

The screw squeeze dryer has several advantages over traditional dehydration methods, making it an ideal choice for dewatering a variety of materials.

1. Efficient dehydration: The screw squeeze dryer can quickly dehydrate materials through mechanical extrusion, greatly shortening the processing time.

2. Low energy consumption: Compared with traditional methods such as drying, the screw squeeze dryer consumes less energy because it does not require heating or high-temperature processing.

3. Maintain material quality: The screw squeeze dryer will not cause damage to the quality of the material during the dehydration process, and maintains the taste, color and nutritional content of the original material.

4. Automated operation: The spiral squeeze dryer can realize automated operation, reducing labor costs and operating difficulty.

5. Strong adaptability: The screw squeeze dryer is suitable for a variety of materials and can be adjusted and customized according to the requirements of different materials.

3. Application cases of screw squeeze dryer

Food Processing: Dehydration of fruits and vegetables is a common application in food processing. The screw squeeze dryer can quickly remove the moisture from fruits and vegetables and make products such as dried fruits and vegetables.

Chemical industry: Dehydration of chemical raw materials is crucial to product stability and quality. The screw squeeze dryer can be used to dehydrate various powder and granular chemical raw materials.

Agricultural waste treatment: Dehydrating agricultural waste such as straw, feed residue, etc. can reduce storage and transportation costs and reduce environmental pollution.

Environmental protection field: Sludge dewatering is one of the important tasks in the environmental protection field. Screw squeeze dryers can be used for sludge dewatering, reducing wastewater treatment costs and environmental impact.

in conclusion

As a high-efficiency, low-energy-consuming dehydration equipment, the screw squeeze dryer plays an important role in the dehydration treatment of various materials. It can not only improve production efficiency and reduce energy consumption, but also maintain the quality of materials and has wide applicability. Therefore, it has broad application prospects in food processing, chemical industry, agriculture, environmental protection and other fields. With the continuous development of industrial technology, the application of screw squeeze dryers in various fields will become more diversified and efficient.
