Overview

The key performance parameters of the MVR drum scraper dryer have been carefully designed and optimized to meet the production needs of different industries. The soundproof cover design is adopted to provide a good working environment for operators.

Product Details

MVRDrum scraper dryerIt is an efficient and energy-saving drying system that combines mechanical steam recompression technology with drum scraper drying. By recovering the latent heat of evaporated steam, it reduces energy consumption by 50-70%, making it particularly suitable for low-temperature drying of heat sensitive and high-value materials.

1、 Working principle

MVRDrum scraper dryerThe workflow begins in the initial stage, with external steam preheating the system to the set temperature. In the drying cycle, the steam inside the drum evaporates the moisture in the material, and the generated evaporated steam is pressurized by the compressor, with a temperature rise of up to 10-25 ℃. The pressurized steam returns to the drum as a heat source, continuing to provide energy for material drying.

Core components:

roller

scraper

compressor

condenser

control system

2、 Technical features

Compared with traditional drying equipment, MVRDrum scraper dryerThe COP value (energy efficiency ratio) is 8-15, which is much higher than traditional drying equipment and suitable for low-temperature drying of heat sensitive and high-value materials.

3、 Key performance parameters

MVRDrum scraper dryerThe key performance parameters have been carefully designed and optimized to meet the production needs of different industries. The soundproof cover design provides a good working environment for operators.

4、 Workflow:

Initial stage: Connect the external steam preheating system to the set temperature.

Drying cycle:

The material forms a thin film (0.1-3mm) on the surface of the drum.

The evaporated steam is pressurized by the compressor (with a temperature rise of 10-25 ℃).

Compressed steam returns to the drum as a heat source.

Energy balance: Only 5-15% fresh steam is needed to maintain the system.

5Industry Applications

MVRDrum scraper dryerHas outstanding application performance in multiple industries. In the food industry, drying whey protein can avoid Maillard reaction and ensure product quality. In the field of fine chemicals, it can be used for drying dye intermediates and electronic chemicals.

6、 System selection and maintenance

Choosing MVRDrum scraper dryerIt is necessary to comprehensively consider factors such as production scale and material characteristics. Characterized by simple structure and easy maintenance; Strong resistance to liquid impact. At the same time, configuration solutions are also provided, suitable for industrial production.

In order to ensure the long-term stable operation of the equipment, it is necessary to develop comprehensive maintenance and energy-saving optimization measures. Regular preventive maintenance, such as daily compressor vibration testing; Check the wear of the scraper every week, and the blade thickness should be ≥ 85% of the original value; Every month, check the scaling situation of the heat exchange tubes and require a pressure difference increase of ≤ 10%. In addition, the waste heat of condensed water can be utilized to preheat the feed, which can save 12% energy.

7、 The advantages of MVR dryer in environmental protection are mainly reflected in the following aspects

Efficient and energy-saving: MVR (mechanical vapor recompression) technology compresses secondary steam to increase its pressure and temperature, allowing it to be reused as a heat source. This reduces the demand for externally generated steam, thereby significantly reducing energy consumption.

Reducing greenhouse gas emissions: Due to the efficient and energy-saving characteristics of MVR dryers, dependence on fossil fuels is reduced, thereby reducing greenhouse gas emissions such as carbon dioxide and helping to mitigate global warming.

Reduce wastewater discharge: The MVR dryer can evaporate and recover the water in the wastewater during treatment, reducing the amount of wastewater discharged. This is particularly important for industrial wastewater treatment, as it helps to reduce pollution to water bodies.

Resource recycling: MVR dryers can recycle the latent heat of secondary steam, achieving energy recycling. In addition, useful substances such as salts and organic compounds in the treated wastewater can also be recycled, reducing resource waste.

Reducing operating costs: Due to the high-efficiency and energy-saving characteristics of MVR dryers, long-term operation can significantly reduce the energy and operating costs of enterprises, thereby improving their economic benefits.

Reducing noise pollution: Modern MVR dryer designs often consider noise control, using measures such as soundproof covers to reduce the noise during equipment operation and minimize the impact on the surrounding environment.

Strong adaptability: MVR dryer is suitable for various industries and materials, including food processing, and can treat crystallization mother liquor and wastewater of various high concentration solutes, with wide applicability and flexibility.
