As long as there is air, in theory there are shaped equipment use。
As the society for the improvement of energy saving, environmental protection, and to the continuous development of the technology itself, can gather comprehensive advantage technology and its product is fully play, also is expanding its application field.
Roca's heat can get together to industrial hot water technology and drying technology, has been steamed wine, lees drying, drying of flue-cured tobacco and betel nuts, urban sludge, seafood, agricultural and sideline products, medicine, food, textile, chemical, electroplating, heating, slaughtering, aquaculture and other widely used in different industries and sectors, has created a huge social benefit and economic benefit.
What is dry
Usually refers to the dry heat in the wet material and send out volatile water and process of solid product to obtain a certain moisture content. Thermal drying, have the following two kinds of process, and control the drying rate.
1: the process of energy transfer to the surface of the material from the surrounding environment, make the material surface water evaporation, liquid discharge from the material surface in the form of water vapor, the process rate depends on the temperature, air humidity, air velocity, heat transfer area of material and pressure conditions。 Also known as the constant speed drying process。
Process 2: internal moisture to the surface of materials, surface evaporation to occur again. Material internal moisture migration is a function of material properties, temperature and humidity. This process is also called the falling rate drying process.
Roca, production of high temperature drying system system design generally follow the following principles:
1, must ensure the stability and reliability of the drying system。 To ensure the quality of the drying material is not damaged in the process of drying;
2, according to the actual needs, tailored product system;
3, ensure drying process of green, environmental protection, energy saving;
4, the combination of limited use different ways of drying equipment and, in order to achieve the best drying quality and drying efficiency;
5, as far as possible ensure the generality, multi-usage, improve equipment efficiency, reduce the investment cost.
The drying process
Using the equipment in the evaporator absorbs the heat from the air, or recovery of exhaust gas residual heat in the process of drying, after compressor power, the energy transport (transfer) to the drying room, hot air drying room after repeated circulation heat absorb the moisture in the material, is water vaporizing discharge material surface, after hot platoon is wet or the process of condensation, water the water out of the material, finally realizes the continuous drying of materials.
