Dehydroacetic acid dryer

What is dehydroacetic acid? Dehydroacetic acid, solid white or light yellow crystalline powder, odorless, tasteless, melting point 108 ~ 110 ℃, boiling point 270 ℃, is a low toxicity, high-efficiency antiseptic and mildew inhibitor. In acid and alkali conditions have a certain antibacterial effect, especially on mold inhibition. It is an effective disinfectant. Storage method: 1. Store in a cool, dry and well ventilated warehouse

What is dehydroacetic acid?

Dehydroacetic acid, solid white or light yellow crystalline powder, odorless, tasteless, melting point 108 ~ 110 ℃, boiling point 270 ℃, is a low toxicity, high-efficiency antiseptic and mildew inhibitor. In acid and alkali conditions have a certain antibacterial effect, especially on mold inhibition. It is an effective disinfectant.

Storage method:

1. Store in a cool, dry and well ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The package is sealed.

2. It should be stored separately from acids and edible chemicals, and should not be mixed. The storage area should be equipped with suitable materials to contain the leakage.

Working principle of dehydroacetic acid dryer:

  the material enters the machine from the feed inlet. Under the action of the vibration force, the material is thrown along the horizontal fluidized bed and moves forward continuously. The hot air passes through the fluidized bed upward to exchange heat with the wet material. After the wet air is removed by the cyclone separator, the exhaust air is 1:3 discharged. The dry material is discharged from the discharge inlet.

Dehydroacetic acid dryer is suitable for materials:

  it is suitable for drying and cooling of powdery and granular materials in chemical industry, pharmaceutical industry, food industry, dehydrated vegetable industry, grain industry and mineral industry. Such as: citric acid, monosodium glutamate, borax, ammonium sulfate, compound fertilizer, lol, silk, soybean meal, distiller's grains, seeds, slag, sugar, etc.



The performance characteristics of dehydroacetic acid dryer are as follows

The vibration source is driven by vibration motor, with stable operation, convenient maintenance, low noise and long service life.

Uniform fluidization, no dead space and blow through phenomenon, can obtain uniform drying and cooling products.

It has good adjustability and wide application range. The thickness of material layer, moving speed in the machine and the change of full amplitude can be adjusted steplessly.

It can be used for drying fragile materials, and the irregular particles will not affect the working effect.

Fully enclosed structure can effectively prevent cross infection between materials and air, and clean working environment.

High mechanical and thermal efficiency, good energy saving effect, 30-60% energy saving than general drying device.

There are three braking modes of vibrating fluidized bed dryer

1. Electromagnetic braking is to lock the shaft of vibrating fluidized bed by mechanical device. Electromagnetic braking is generally started after SV and off, otherwise the amplifier may be overloaded. The dynamic brake is generally started after SV, off or main circuit is powered off, otherwise the dynamic braking resistance may overheat.

2. Regenerative braking refers to that the energy generated by the braking is fed back to the DC bus through the inverter circuit when the vibration fluidized bed decelerates or stops. After being absorbed by the resistance capacitance circuit, the regenerative braking can only work when the server is working normally. In the case of fault, emergency stop, power failure, etc., there is no legal vibration fluidized bed, and the work is carried out automatically by the system.

3. The dynamic brake is composed of dynamic braking resistor. In case of fault, emergency stop and power failure, the mechanical feed distance of vibrating fluidized bed is shortened by energy consumption braking. The dynamic brake does not need power supply and needs external relay control.
