During the communication with customers, some customers asked:

one twin-screw extruder that can make all products or as many products as possible.

I.Food Category

Before answering this question, let’s make sure we have same understanding on foods category.

The chart below illustrates some common classifications of extruded leisure foods.

According to the production process/taste/application, it is divided into 9 major categories.

 

Category No.	Category Name
1	Baked Puffed Snacks
2	Fried Puffed Snacks
3	2d/3d Pellets Snacks
4	Fortified Rice, Instant Rice
5	TVP (Soya Chunks)
6	Corn Flakes
7	朝食用シリアル
8	Baby Rice Cereal
9	Bread Crumbs
10	Dog Food

II.Multi-Purpose Extruder and Specific Extruder

We have Specific extruder that is especially for a certain category of food, and also have Multipurpose extruder.

 

If your product target is clear: you need an extruder to make all the shapes of products under a CERTAIN category.

Then, for example, our WINCI model extruder is specially designed for 2d/3d pellets.

It can produce 90% of the 2d/3d pellets products on the market with perfect quality.

You only need to add the corresponding molding machine or mold shape.

PS: The remaining 10% of the 2d/3d pellets products are made by non-extrusion process, which will not be introduced here.

 

If your product target is NOT clear:

For example, our SLG-70A twin-screw extruder is good at all baked puffed snacks, some fried puffed snacks, breakfast cereals, baby rice cereal, bread crumbs, and some dog food.

 

Our 72-BJ-9 twin-screw extruder is good at producing all 2d/3d pellets products , fortified rice, nutritious rice, textured protein, corn flakes, and some dog food.

By changing the screw, 72-BJ-9 extruder can also produce baked puffed snacks, some fried puffed snacks, breakfast cereals, baby rice cereal, and bread crumbs.

That said, the 72-BJ-9 can produce almost every product type.

III. Food Competitiveness

You may really like 72-BJ-9, as it can make all kinds of categories.

While considering the advantage of multi-purpose extruder, please also pay attention to other factors.

We know, the purpose to open a food factory is to make business.

So any food factory need to make competitive products to win the market.

The following table shows the factors which affect the competitiveness of food.

	Food Competitiveness Factors
1	Food Quality	Texture, appearance, taste,mouth feel
2	Average Manufacturing Cost per KG	Raw materials, electricity, gas, labor cost
3	Marketing Advantage	Weight-to-volume ratio, new shape, others
4	Machine Maintenance Cost	Simplicity and complexity of production line and machine

 

 

IV.Multi-Purpose Extruder’s Different Performance

When all the above factors are taken into account, when the multi-purpose extruder 72-BJ-9 compares to each product’s Specific extruder, we get following charts:

 

 

 

From chart above, we can get:

A multi-purpose twin screw extruder has different performance for producing different foods.

For some foods, it performs very well, some has such or that disadvantages.

 

V.Summary:

-We have Specific extruders that are specifically used for the production of a certain category of product.

– We also have extruders that are very suitable for the production of 4-5 category of products.

– We also have extruders that can produce all 10 category of products, but for 2 of which are VERY SUITABLE, and the other 8 are not as good as the production effects of Specific extruders.

 

Which extruder to choose depends on your production plan.

Not a simple ‘yes’ or ‘no’ .

If you plan to produce 3-5 categories firstly with extremely competitiveness on your market, then specific extruder is best choice for you.

If categories diversification is very important for you, and has less attention on the competitiveness, then an universal extruder is better.
