CT-C Hot Air Circulating Drying Oven

Description of CT-C Hot Air Circulating Drying Oven

The CT-C series hot air circulation oven is equipped with a low-noise, high-temperature-resistant axial flow fan and an automatic temperature control system. The entire circulation system is fully enclosed, which improves the thermal efficiency of the oven from 3%-7% of the traditional drying room to the current 45%-50%, the highest thermal efficiency can reach 60%. The successful design of the CT-C series hot-air circulation oven has enabled China's hot-air circulation oven to reach the advanced level at home and abroad, saving a lot of energy for China and improving the economic benefits of the enterprise.

Most of the hot air circulates in the oven, with high thermal efficiency and energy saving. Using the effect of forced ventilation, the oven is equipped with an adjustable air distribution board, so that the materials are dried evenly. The heat source can be steam, hot water, heat-conducting oil, electricity, hot blast stove, of a wide range of choices. The whole machine has low noise and stable operation. Automatic temperature control, easy installation and maintenance.

Basic principles of plant design

  • The ground should be paved with non-permeable, non-absorbent, non-toxic, non-slip materials, and the ground should be seamless and easy to clean and disinfect. The ground should have an appropriate slope (1.0%-1.5% is appropriate) and have a good drainage system. The drainage ditch is an arc-shaped open ditch. If it is drained in a dark ditch, rodent nets must be set up. The ground is solid, the thickness of the concrete layer is not less than 50mm, and the ground should be covered with tiles or terrazzo or painted with environmental resin.
  • The wall should be paved or coated with light-colored, mildew-proof, anti-permeable, non-toxic materials, and the surface should be smooth and easy to wash and disinfect. The top corners, wall corners, and ground corners are arc-shaped to prevent dirt from accumulating and facilitate cleaning.
  • The ceiling should be coated or decorated with light-colored materials that do not absorb water, have a smooth surface, anti-mold, and anti-leakage. It should have an appropriate slope to reduce condensation and dripping on the structure.
  • Doors and windows should be tight and made of non-deformable and corrosion-resistant materials. If there is an inner window sill, it should be inclined down 45°. Doors and windows must be equipped with effective facilities for preventing mosquitoes, flies and insects. The door should be able to close automatically and tightly.
  • Ventilation equipment: the workshop must be equipped with ventilation equipment. The air flow direction should avoid flowing from the unclean area to the clean area. The vent must be equipped with a corrosion-resistant protective cover that is easy to clean and replace, and the air inlet must be at least 2m above the ground and far away from pollution sources and exhaust vents.
  • Daylighting and lighting: The workshop or working surface should have sufficient natural or artificial lighting. The lighting coefficient of the workshop should not be lower than the standard IV level; the mixed illuminance of the working surface of the inspection site should not be less than 540lx; the illuminance of the working surface of the processing site should not be less than 220lx; other places should not be less than 110lx. The lamps installed above the production line in the workshop must have safety protection devices to prevent the lamps from being broken and contaminating food.
  • Fire-fighting requirements: The process system does not require special fire-fighting facilities, and the fire-fighting of the factory building is set by the construction unit in accordance with the law.
  • All equipment does not require anchor bolts, protective barriers and enclosures.
