Dehydroacetic acid, solid white or light yellow crystalline powder, odorless, odorless, melting point 108 ~ 110 ° C, boiling point 270 ° C, is a low toxicity high-efficiency anti-corrosion, anti-mold agent. It has certain antibacterial effects under acid and alkali conditions, especially for molds. It is an effective disinfectant.
Storage method:
1. Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat. Protect from direct sunlight. The package is sealed.
2. It should be stored separately from acids and food chemicals, and should not be mixed. The storage area should be provided with suitable materials to contain spills.
Dehydroacetic acid dryer Working principle:
The material enters the machine from the inlet of the feed. Under the action of the vibration force, the material is thrown along the fluidized bed of the horizontal plane and moves forward continuously. The hot air passes through the fluidized bed and exchanges heat with the wet material, and the humid air is removed by the cyclone. Exhausted by exhaust 1:3. The dry material is discharged from the discharge inlet.
Dehydroacetic acid dryer Adapt to materials:
It is suitable for drying and cooling of powdery and granular materials in chemical, pharmaceutical, food, dehydrated vegetables, grain, minerals and other industries. Such as: citric acid, monosodium glutamate, borax, ammonium sulfate, compound fertilizer, dill, silk, soybean meal, distiller's grains, seeds, slag, sugar and so on.
Dehydroacetic acid dryer Features:
◎The vibration source is driven by vibration motor, which is stable in operation, convenient in maintenance, low in noise and long in life.
◎The fluidization is well-proportioned, and there is no dead space and blow-through phenomenon, so that uniform drying and cooling of the product can be obtained.
◎ Good adjustability, suitable for wide surface. Stepless adjustment is achieved by layer thickness and movement speed in the machine as well as full amplitude changes.
◎The damage to the surface of the material is small. It can be used for the drying of fragile materials. When the material particles are irregular, it will not affect the working effect.
◎ adopts a fully enclosed structure. 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, energy saving 30-60% compared with general drying equipment.
Three braking methods for vibrating fluidized bed dryers:
1. The electromagnetic brake is to lock the shaft of the vibrating fluidized bed by mechanical means. The electromagnetic brake is normally started after SV and OFF. Otherwise, the amplifier may be overloaded. The dynamic brake is normally started after SV, OFF or the main circuit is powered off. Doing so may cause the dynamic braking resistor to overheat.
2. Regenerative braking means that the vibration fluidized bed feeds back the energy generated by the braking to the DC bus through the inverter loop during deceleration or stop, and is absorbed by the RC circuit. The regenerative braking must be performed when the servo is working normally. In the case of failure, emergency stop, power failure, etc., the vibrating fluidized bed cannot be braked, and the work is automatically performed by the system.
3. The dynamic brake is composed of dynamic braking resistor. When the fault, emergency stop and power supply are cut off, the mechanical feed distance of the vibrating fluidized bed is shortened by the energy consumption braking. The dynamic brake does not need power supply when working, and external relay control is required.
