Drying production line
Drying line (tunnel furnace) working principle: '
The dried wet material is sent to the hopper by a belt conveyor or a bucket elevator, and then fed through the hopper through the feeding pipe into the feeding end. The slope of the feeding pipe is greater than the natural inclination of the material so that the material flows smoothly into the dryer. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the lower end, and is in countercurrent contact with the material, and the heat carrier and the material are simultaneously flowed into the cylinder. As the rotating material of the cylinder is moved by gravity to the lower end. During the forward movement of the wet material in the cylinder body, the heat supply of the heat carrier is directly or indirectly obtained, so that the wet material is dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor. A copy board is arranged on the inner wall of the cylinder, and its function is to copy and sprinkle the material, so that the contact surface of the material and the air flow is increased to increase the drying rate and promote the advancement of the material. The heat carrier is generally classified into hot air, flue gas, and the like. After the heat carrier passes through the dryer, a cyclone is generally required to trap the material contained in the gas. If you want to further reduce the dust content of the exhaust gas, you should also discharge it after passing the bag filter or the wet dust collector. '
The working principle of the drying line is generally to use the far infrared to heat the furnace, and then the interior is made of ceramic and stainless steel, so that the infrared light can shine into every corner of the furnace, and then the temperature is evenly heated to transfer the energy. Give the object. '
The workshop belt line is a kind of equipment that uses the products and foods in the infrared technology team to heat the equipment. It is also a common food drying line on the market. The traditional drying line uses coal and fuel as fuel for heating. Since the energy crisis, countries around the world have developed various conservation and alternative energy technologies to improve energy efficiency and diversify energy. The radiant heating method has been widely used to replace the conventional hot air heating and drying system because of its particularity as one of the efficient heating and drying techniques. '
Radiation heating method includes infrared, ultraviolet, microwave and laser lamps, of which infrared is convenient and common. The working principle of infrared tunnel furnace is basically the principle of infrared electromagnetic radiation heat transfer. Directly heat transfer to achieve the purpose of heating and drying objects, thereby avoiding the energy loss caused by heating the heat transfer medium, saving energy, and at the same time, the infrared rays are easy to produce, controllable and good, and have rapid heating and drying time. Short, increased productivity, improved product quality and equipment space savings. '
In the electromagnetic spectrum, electromagnetic radiation having a wavelength between red light and microwave. Outside the range of visible light, the wavelength is longer than red light and has a significant thermal effect. Infrared drying technology utilizes its unique thermal effects. Infrared rays are easily absorbed by objects and have the characteristics of radiation, penetrating power and electromagnetic waves having special affinity for polar substances such as water molecules. They penetrate deep into the material and are converted into internal energy of the object, so that the object can be dried in a very short time. The required thermal energy, at the same time inside and outside, is more effective and completely removes the bound water in the material, thereby achieving a more ideal drying effect, thereby greatly improving the drying speed and improving the product quality.
