Energy Saving Small-sccupied space Hollow Paddle Dryer for Spent Grain
Product
Shengman company by absorbing foreign advanced technology, based on to improve and optimize the design of the wedge-shaped hollow paddle dryer can treat paste, granular, powder, paste material through indirect heating or cooling, to achieve drying, cooling, heating, sterilization reaction, low temperature calcination and other unit operations. Wedge-shaped mixing device in a special heat transfer blade, has a high heat transfer efficiency and heat transfer surface self-cleaning function.
Paddle dryer has following main features:
1. Compact structure, large efficient heat transfer area, and small occupied
area.
2. Stirring is uniform, heat efficiency is high, and drying efficiency is good.
3. Paddle shafts can mesh each other, and have self-clean function, it can
avoid material stick on the wall.
4. Energy consumption is low, and operating cost is low
5. Little dust carried out, little material loss
6. Heat indirectly, material can not be polluted
7. Rotary speed of paddle shaft is low, it will not destroy the shape and
property of product
8. Operating flexibility is large, running is stable and reliable.

Performance characteristics
1. The energy consumption of pulp-leaf dryer is low: because of indirect heating, there is no large amount of air to take away heat. The outer wall of the dryer is also equipped with insulation layer. For slurry material, only 1.2 kg of water vapor is needed to evaporate 1 kg of water.
2. The cost of the pulp-leaf dryer system is low: having a huge heat transfer surface in the unit effective volume shortens the processing time and reduces the size of the equipment. It greatly reduces the building area and space.
3. Processing materials in a wide range: using different thermal media, can not only deal with heat-sensitive materials, but also deal with materials that need high temperature treatment. Common media are: steam, heat conducting oil, hot water, cooling water, etc.It can be operated continuously or intermittently, and can be applied in many fields.
4. Small environmental pollution: do not use carrying air, dust material entrainment is very little. Solvent evaporation is very small and easy to handle. For contaminated materials or working conditions requiring recovery of solvents, it can be used.Closed circuit circulation.
5. Low operating cost: structure. Small wear and tear, low maintenance costs. A kind of
6. Operation stability: Because of the special compression-expansion stirring action of the wedge-shaped blade, the material particles are fully in contact with the heat transfer surface. In the axial region, the gradient of temperature, humidity and mixing degree of the material is very small, thus ensuring the stability of the process.
