500-700kg/h Puffed Snack Extruder for Corn Rice Production

Product Introduction for Puffed Snack Extruder 

The 500–700kg/h puffed snack extruder is an industrial food processing machine designed for the production of grain-based puffed snacks. Built with durable steel construction and a single screw extrusion system, it processes raw materials such as corn, rice, wheat, oats, and barley into crispy snack products.

This equipment addresses the need for efficient and uniform snack manufacturing by combining high-temperature extrusion and die forming technology. It enables continuous production of different snack shapes while maintaining consistent texture and quality.

The machine is suitable for commercial snack factories, food processing plants, and industrial puffed food production lines that require reliable output and versatile snack shaping capabilities.

Working principle：

Raw grains such as corn, rice, wheat, oats, or barley are fed into the extruder hopper. The rotating screw moves the material forward while friction between the screw and barrel generates heat and pressure, cooking and gelatinizing the grains. The cooked mixture is forced through a die where the shape is formed. A rotating cutter trims the extruded product into the desired size. By changing dies, the machine can produce shapes such as balls, tubes, sticks, rings, stars, and flowers while maintaining uniform puffing and crisp texture.

Main features：

• Single screw extrusion system provides stable processing and consistent puffing quality.
• Compatible with multiple grains including corn, rice, wheat, oats, and barley.
• Interchangeable dies enable production of balls, tubes, rings, sticks, and decorative shapes.
• Efficient friction heating technology cooks grains evenly while maintaining product texture.
• Durable steel construction ensures long service life and reliable operation in factories.
• Continuous extrusion process improves productivity and reduces manual intervention.

 

Application scenarios：

• Corn puff snack production lines in commercial food factories
• Grain-based extrusion processing for wheat, oat, and barley snacks
• Industrial puffed snack production for supermarkets and wholesale markets
• Ready-to-eat snack manufacturing facilities with continuous extrusion processing
• Food processing plants developing new cereal-based puffed snack products

FAQ

Q1: What raw materials can this extruder apply to?
A: It is suitable for corn flour, rice flour, corn grits, rice and other grain raw materials, and can add seasonings to make flavored puffed snacks.

Q2: Is this extruder suitable for 24-hour continuous production?

A: Absolutely. It adopts heavy-duty structure and wear-resistant parts, supporting long-term continuous operation, ideal for industrial large-scale production.

Q3: Are all food-contact parts food-grade stainless steel?

A: Yes. All parts touching food are made of 304 food-grade stainless steel, which is corrosion-resistant, easy to clean and meets international food safety standards.

Q4: Can we change molds to make different snack shapes?

A: Sure. We provide various interchangeable molds, you can make strips, rings, balls and other shapes by replacing molds and adjusting parameters.
