When refrigerated trucks transport more perishable food, they need to be aware of the air circulation in the cabin, and air circulation is also one of the main factors that can protect easily corroded foods. If it is said that the braked air has not been able to properly protect the temperature of the article since it can perform a normal cycle, then it has no meaning whatsoever for the capacity of refrigeration. The air circulation brings the heat of the item through the floor, the ceiling and the heat from the bulkhead to the refrigeration unit. After passing through the refrigeration unit, the heat is discharged.

The thermal insulation of refrigerated trucks is mainly suitable for transporting those perishable food vehicles must be well insulated to block the flow of heat carriers through the bulkheads of refrigerated trucks. The thermal insulation quality of the vehicle can be measured, and the thermal conductivity coefficient is U, which indicates that the thermal insulation performance is the best. The most commonly used thermal insulation material for refrigerated vehicles is foam. Because they contain the lowest U factor, the weight is also the lightest, and the water resistance is good and no corrosion will occur. At the time of manufacturing, the foaming of the plastic in place was performed, and the advantage of better thermal insulation performance was obtained. Moreover, this manufacturing process can block the air well and may also pass through cracks and cracks. The use of highly polished aluminum and steel skins has the advantage of maximum thermal insulation. Because this kind of material can be reflected on the pavement and the sun's heat, there is also a reflective paint that is used for refrigerated vehicles . However, it should be noted that if the outside of the refrigerated truck does not perform external cleaning, the effect of reflection on any material will also be reduced. If leakage occurs in the door seal of a cold car, there is no more value in using high quality insulation.

Working Principles
The powdery materials is in fluidizing state in the container. It is first heated and mixed by filtered hot air. Then the powder combines with atomizing adhesive solution. After that, the prototype of granule is formed.

The moisture in granules is evaporated, as hot air constantly heats the granules. The adhesive is also solidified in the process of drying. The repeated drying process finally contributes to the microporous spherical granules.

The Fluidized Drying Granulator can be used to make tables, instant herbal medicine and capsule in pharmaceutical industry, cocoa, coffee, milk powder, fruit granules and flavoring in food industry, and agricultural pesticide, feedstuff, fertilizers, pigments and dyestuff in other industries. It is also suitable for drying of wet powder materials or wet particles.

1. Granules made by our fluidized drying granulator have good dissolvability and fluidity. So there is no dust pollution.
2. It has functions of mixing, drying and granulation.
3. Anti-static electricity filter cloth is adopted to make the fluidized drying granulator safe to use.
4. Pressure bleeder hole is designed for security.
5. It features easy charging and discharging of materials, and it is also easy to clean.
6. Our fluidized drying granulator conforms to the standards of GMP.
