Macaroni/pasta is been produced by single-screw extruder through extruding cooking, using potato starch, corn starch, cassava starch, wheat flour, corn flour etc. as raw material, they are in different shape like shell, spiral, square tube, round tube, little springs, wheels and so on. It needs frying to get expanded. After dry fried puffing again, becomes a crisp delicious, delicious snack food.  

I. Technological process: raw material preparation, stir, extrusion, cooling, drying and fried, transport, ascend, seasoning, (packaging).

II. Equipment composition:

1. flour mixer:choose different models according to the different production of mixer machine, choose the production line of the BF-Ⅰ mix machine.
2. single screw host: according to the different varieties of products to choose different types of extrusion host, according to configuration of the production line is commonly used to form a complete set of the production line, the line choose single screw host;
3. delivery cut-off machine:delivery,cut off
4. cooling machine of the wind bed:used for rapid cooling blowing cadres to distribute sticky, stick together
5. hot air drier:used to dry products
6. automatic fryer: fried oil machine

III Main character:

1. This production line is reasonable design, high degree of automation, accurate parameter control.

2. Adopts advanced frequency control of motor speed technology, make the equipment run more smoothly and save electricity.

3. Screw using alloy steel nitriding treatment, screw longer life.

4. Forced lubrication system to guarantee the part equipment transmission with a longer life.

5. More intuitive visual automatic temperature control system, temperature control, parameter more accurate.

IV. Technological parameters:

V. Capacity:  15kg/h;30-40kg/h;50-60kg/h;100kg/h,260kg/h;400-500kg/h;600-800kg/h etc.  

VI. The features of the  snack equipment 

a. The screw is made of alloy (38CrMoAL) by nitriding process, high strength and wear- resting. And it as good selfcleaning ability and does not need to discharge or clean the barrel and screw, when roasting or replacing of materials.

b. It adopts speedadjusted converter on feeding system, extrusion system and cutting system. Food grade stainless steel twin screw feeding machine guarantees stable materials feeding in the whole food process.

c.The gearbox has automatic lubrication function, with extends gear life. 

d. Radiator is increased on driving part for forced cooling effect, and it ensures extruder operate safely.

e. Barrel with watercooled circulation, it makes extruder can be used not only for corn/rice, also for wheat flour/starch which are raw materials with high viscosity. Through different moisture-   extrusion temperature ratio, it can make whole- expanded and half xpanded as different  type of products.

f. Cutting knife fixed in the die head seat, rotary cutting by V-belt drive.
