SG type temperature and humidity double control tunnel dryer

The new SG type circulating through flow temperature and humidity double control drying equipment is divided into integral metal type, split drying room type or drying channel type. Different types can be flexibly selected first for different material varieties and different investment requirements of users.

The SG type circulating through flow temperature and humidity dual control drying equipment is composed of single or several drying units (depending on the drying materials, air inlet and circulation mode). Each drying unit section includes circulating fan, heating device, fresh air supplement system, tail gas emission system, temperature control system and tail gas humidity control system. The process flow is as follows: after the materials come out of the previous process, they enter the dryer after manual loading; The cold air enters the centrifugal fan from the fresh air make-up port and is heated by the heat exchanger (mixed with the dry hot air from the hot blast stove when the hot blast stove is heated), and then enters the tunnel to fully contact with the wet materials for heat and mass exchange. The moisture in the materials is evaporated into steam, which enters the air duct on the side (or top) of the box together with the hot air, and part of the wet air is emptied from the wet exhaust port, The other part is recycled; Due to the different moisture content of materials in each unit, the proportion of moisture discharge and circulating air in each unit is also different; In the whole drying process, the hot air humidity is also different; At the initial stage of drying, the moisture content of the material is high, and a higher hot air temperature can be selected; In the later stage of drying, the moisture content of the material is low, so a lower hot air temperature can be selected (the specific drying process selection is determined according to the process requirements of different products).

In the drying process, the machine adjusts the moisture discharge and the supplement of circulating air and cold air according to the humidity data to realize the utilization of heat energy, save energy and reduce consumption and improve the quality of products.

characteristic:

1. It is suitable for drying materials for a long time, making full use of effective space and large processing capacity;

2. Drying medium in different drying interval levels, up and down interactive transformation, recycling, high thermal efficiency;

3. The drying temperature and moisture discharge humidity can be set separately according to the characteristics of dry materials, with wide process adaptability;

4. Automatic operation, can be designed into full-automatic or semi-automatic according to the user's situation, which is more labor-saving;

Typical applicable materials:

1. Drying of preserved fruit, pericarp, dried fruit, vermicelli and other foods;

2. Mushroom, Pleurotus ostreatus, agaric and other edible fungi;

3. Hangzhou white chrysanthemum, jasmine, small rose and other flowers;

4. Paste materials, cotton yarn fibers, ceramic products and other materials suitable for drying by tunnel dryer;

5. Various materials that need to be dried for a long time;
