Fumaric acid is a colorless crystals, soluble in water, slightly soluble in cold water, ether, benzene, soluble in water, soluble in ethanol. The product is a medical and optical bleaching agent fine chemical intermediates, as a food additive - sour agent for soft drinks, fruit sugar, jelly, ice cream, also used as sour condiment, is also used as a synthetic resin mordant intermediates. Fumaric special drying machine is widely used in chemical, light industry, medicine, food, plastics, oil, slag, salt, Yan Tang and other industries powder, dry granular materials, cooling, humidification and other operations, but also It can be used to dry cooling, humidification cooling operation.

       Fumaric acid, fumaric acid, also known as (fumaric acid), Corydalis acid or lichen acids, namely fumaric acid (IUPAC name (E) - maleic acid), is a colorless, flammable crystals, carboxylic acid derived from butene. Its chemical formula is C4H4O4. Burning will release fumaric acid maleic anhydride with irritating smoke. It tastes like fruit and Corydalis genus boletus, lichens and seaweed can be found in Iceland.

       Material from the feed inlet into the machine, under the effect of the vibration motor excitation force or otherwise made available in the air distribution plate jump forward, and after the air was filtered, heated to a certain temperature, the air into the dryer at the plenum the material in the dual role of vibration force hot air through the air distribution plate and all of the wind, was carried out between the suspension and the hot air in contact with the heat medium material particles intense turbulence, heat transfer and mass transfer process can be strengthening the dried product is discharged from the discharge port, evaporated water and exhaust gas recovered by the cyclone dust into the atmosphere. Bed body to the bed provides a stable with a certain pressure plenum. Adjusting fan, so that the upper portion of the box in the bed material to maintain slightly negative pressure, to maintain a good dry environment and prevent dust leakage.

① material is heated evenly and heat exchange is fully dry and high intensity, energy-efficient than conventional dryer about 30%. Vibration source is driven by vibration motor, smooth operation, easy maintenance, low noise and long life. Stable fluidization, no dead ends and broken phenomenon. Little damage to the surface of the material can be used for brittle dry material particles does not affect the effect of irregular work.

② fully enclosed structure, effectively prevent cross-contamination between the air and the material, the working environment clean. Adjustable resistance, wide adaptation, material thickness and moved inside the machine speed and amplitude can be adjusted steplessly.

③ Since vibrations are applied, can reduce the minimum fluidizing gas velocity, which can significantly reduce the demand for air, thereby reducing the entrained dust layer, matching heat, fans, cyclones and other specifications can also be reduced accordingly, reducing equipment, energy-saving effect . Can easily adjust the vibration to rely on parameters to change residence time in the dryer. Its plug flow operation reduces the particle size uniformity of the material and regulatory requirements, easy to obtain a homogeneous dry product.
