What are the commonly used heating equipment and heating elements in drying industry? Let's talk about it today。
Commonly used electric equipment 1 far infrared drying oven drying industry principle: also called infrared radiation heater, infrared drying machine is transform electricity or other forms of energy into radiant energy, is the key component in the infrared heating system, infrared drying machine is mainly composed of two parts, namely the application of heat and radiation substrate: anticorrosive coating baking paint dry curing paper drying tea dried vegetable and fruit dehydration, drying, baking bread cookies dry grain such as artificial environment warm home heating heating stage 2 tunnel dryer Principle: by car loading material, make full use of the effective drying space, suitable for a variety of shapes material dry material in drying medium level through the dry range, up and down interaction, and recycling of heat with steam boiler and furnace, the platoon is wet, temperature adjustable, applications are widely used: jelly fruits paste dried fruit dehydration dry fruits and vegetables and other agricultural products baking finish drying silicon force board electrical components such as other industrial materials need to be dry for a long time。
Microwave dryer principle: the use of microwave heat penetrability raise the temperature of the material, make the moisture in the material vaporized evaporation, evaporation of water vapor discharged by the platoon is wet system and achieve the purpose of drying materials application: drying food, medicinal materials, wood, building materials, cardboard or other materials may return the dryer to three principles: the three return the dryer is made up of three concentric diameter different cylinder nested together, instead of interlocking, it was the chain, the structure of this particular decides the size of its production, so this kind of new type dryer is also called three return dryers 6 electrode drying oven Principle: the heating element of the electrode drying box is to convert electric energy into heat energy, through the far infrared radiation element with a large number of far infrared ray irradiation on the electrode, under the action of radiant heat, make the moisture inside the electrode coating quickly evaporate, achieve the removal of moisture, drying electrode application: mechanical electric metallurgy chemical petroleum。
Drum dryer principle: drying machine is a horizontal tilt slightly into the cylinder, materials from high end to join, and the high temperature hot flue gas and material flow into the cylinder, with the rotation of the cylinder, materials run due to the effect of gravity on the low side on the inner wall of the cylinder is equipped with copy board, and sprinkle with copy material, the contact surface is increased and the air flow of material, in order to improve the drying rate and promote the product after drying of material on collecting applications: from the bottom of the lower coal diatomite kaolin straw forage pomace soy sauce residue bagasse abattoir waste organic fertilizer and inorganic fertilizer ammonium phosphate fertilizer sulphur 8 High temperature heat pump dryers principle: using the inverse cano principle, absorbing heat air and transferring them to the room, and realize the temperature of drying room, cooperate with relevant equipment to realize the material drying heat pump dryer choke by compressor heat exchanger heat absorber device such as compressor constitute a circulation system application: nine electric heat drying herbs fruits and vegetables such as sludge drying Principle: by the power make the heating, electric heating tube produces heat source, and through the blower to form inside the oven wind circulation and achieve uniform temperature, to obtain rapid drying effect, to shorten the production cycle, save energy, improve product quality purpose applications such as: mold, spraying, printing, medical, aerospace electronic communications, plastic, cable, plating, hardware, automobile, photoelectric, rubber products。
Principle of rotary dryer, rotary dryer is mainly composed of shell and the central tube is dry material along the shell inner wall and the annular space between the outer wall of the central tube, flue gas burning into the central tube, flowing from left to right, and to pass through the wall to be part of heat drying materials, and then into and through the annular space and the dry material in direct contact, and then by the exhaust fan or chimneys application: metallurgy, building materials, light industry, in the chemical industry, such as ammonium sulfate, alcali sulphide, upcoming powder, ammonium nitrate, urea, oxalic acid, rotary kiln, calcium-magnesia phosphate fertilizer, ordinary superphosphate, heavy calcium superphosphate and three phosphorus Sodium acid drying, mostly using rotary kiln dryer。
Drying industry commonly used electric heating element 1 PTC heating element features, constant temperature heating PTC thermistor temperature fever after the PTC thermistor is the principle of electricity has entered the jump area hot heat resistance, constant temperature heating PTC thermistor surface temperature will remain constant, the temperature and PTC thermistor only the Curie temperature and applied voltage, and has nothing to do with the environment temperature basic applications: electric mosquito medicine mosquito dispeller hand warmers dryer electric hot plate steam iron electric heating bonding apparatus curl hair curler warm hand and foot warmers hand dryer small low heater hair dryer heating machine Dryer dry wardrobe dryer industrial drying equipment 2 electric wire electric wire electric oven oven works the same as the other metal heating elements, are metals after electrify the electric heating phenomenon is refers to the current through a conductor, electric current will produce certain heat conductor and is passed out heating wire itself is metal conductor, namely after the electricity will radiate heat to provide heat energy application: tea dry the clothes drying, etc
