TsungHsing Food Machinery is a continuous fluidized dryer and roaster machine manufacturer and supplier. TsungHsing Food Machinery (TSHS) provides continuous, large-volume, baking, heating, and drying equipment for manufacturing.
The continuous fluidized bed dryer/ roaster has the principle of operation is using floating hot air and being heated by float hot air to achieve uniform drying and roasting effect. First, the air is heated by the heating system, and the hot air is blown to the product by the blower. At the same time, the hot air is circulated through the filter system through the circulation system, and the temperature is controlled, the heat exchange rate is increased, and achieves the energy saving effect.

Drying: Flakes or granules such as rice, wheat, breadcrumbs (raw materials used in pork coating process).
Roasting: Rice, peanuts, coffee, nuts and snack foods (e.g. Shrimp Strips) puffing.

The continuous fluidized bed dryer/ roaster of TSHS is mainly divided into heating system, conveying system, filtration system and circulation system according to the structure and function:

1. Heating System:

The heating system is arranged at the uppermost part of the equipment. It’s function is to heat the air flowing through to the set temperature, and then blow the hot air through the air blowing pipe to the surface of the product through the blowing of the air blower to mature the product and achieve the effect of drying or roasting.


2. Conveying System:

After the raw material enters the fluidized bed from the feeding conveyor, the vibration device under the fluidized bed can make the raw materials jump off the surface of the fluidized bed and then fall down. During the process, the touch area between the raw materials and the hot air can be increased, and the heat exchange rate is improved. In order to achieve the purpose of uniform product maturity. At the same time, there is also a blower device in the conveying system, which blows the product from the feeding section to the discharging section, so that the raw materials can not only have vertical movement, but also move laterally parallel to the discharging port, thereby achieving the purpose of continuous production.


3. Filtration System:

After heating the raw materials, the hot air temperature drops suddenly but there is still residual temperature. At this time, it will be fed into the filtration system, filtering the dust in the air and the particulate impurities generated in the production to avoid polluting the product, and then return to the heating system for hot air recycling and heating.

4. Circulation System:

The hot air passes through the heating system → conveying system → filtering system and then returns to the heating system, which is a hot air circulation system; by the recycling and reheating of the hot air, the energy saving and the heat exchange rate can be achieved.
