What is Citric Acid
Citric acid (CA), also known as citric acid, has a molecular
formula of C₆H₈O₇. It is an important organic weak acid. It is a
colorless crystal, odorless, easily soluble in water, and its
solution is acidic. In biochemistry, it is an intermediate in the
citric acid cycle (tricarboxylic acid cycle), which occurs in the
metabolism of all aerobic organisms. Citric acid is widely used as
an acidity regulator (GB2760-2014), flavoring agent and chelating
agent.
Working Principle
The material enters the machine from the feed inlet. Under the
action of vibration force, the material is thrown along the
horizontal fluidized bed and moves forward continuously. After the
hot air passes through the fluidized bed upward and exchanges heat
with the wet material, the wet air is discharged by the exhaust air
at a ratio of 1:3 after dust removal by the cyclone separator. The
dry material is discharged from the discharge inlet.
Applicable materials
It is suitable for drying and cooling of powdered and granular
materials in the chemical, pharmaceutical, food, dehydrated
vegetables, grain, mineral and other industries. Such as: citric
acid, monosodium glutamate, borax, ammonium sulfate, compound
fertilizer, shredded radish, soybean meal, lees, seeds, slag,
sugar, etc.
Performance characteristics
◎The vibration source is driven by a vibration motor, which runs
smoothly, is easy to maintain, has low noise and long service life.
◎The fluidization is uniform, without dead gaps and blow-through
phenomena, and uniform drying and cooling products can be obtained.
◎Good adjustability and wide application. The thickness of the
material layer, the speed of movement in the machine and the change
of the full amplitude can all be adjusted steplessly.
◎ Little damage to the surface of the material. It can be used to
dry fragile materials. Even if the material particles are
irregular, it will not affect the working effect.
◎ Fully enclosed structure is adopted. It effectively prevents
cross infection between materials and air, and the working
environment is clean.
◎ High mechanical efficiency and thermal efficiency, good energy
saving effect, can save 30-60% energy compared with general drying
devices.
