Dry Puffing and Wet Puffing on Extruder TPH200C

Extruder is mainly consist of carriage, pulley cover, motor base, the main motor, lubricating oil, base, cutting device, extrusion assembly, bypass, conditioner and front support. Extruder is the key in the whole system. The extruder can be used for processing different materials such as corn, flour, soybean, suckling pig feed and beans. The physical properties of these materials vary widely, rice flour's starch content is very high; and soybean meal, fat content is high, without starch. Therefore, in the processing with different materials for an extruder, in order to get products with good qualities, it needs a good extruder. Selecting a different configuration generally refers to choose a different pressure ring, the screw and the feeding device.

TPH200C type extruder as a major processing machine, is a typical wet bulking device. The extruder is equipped with conditioner, the material in the conditioner role in the use of steam curing of materials for pre-obtained material and after pre-cooked and then extruded into the extruder, extruder can effectively improve the capacity and reduce feed power consumption, and can also reduce material loss in the process.

The extruder can also be used as dry puffing machine in some cases.
(1) Soybean
Extruded soybean can use dry puffing and wet puffing.
(2) Corn
Extruded soybean can use dry puffing and wet puffing.
a. The advantage of dry puffed corns:
It is don't need too many investments, just conditioner and boiler.
Polenta requires special high degree (> 98%) is more appropriate to use dry puffing;
b. Disadvantage of dry puffed corns:
Corn loss: Dry puffing is higher;
Loss of nutrients: Dry puffin is higher;
Processing power consumption: Dry puffin is higher;
Consumption of wearing parts: Dry puffin is higher.
(3) Suckling Pig Feed and Beans
Extrude pig feed and beans, wet puffing is better than dry puffing.
