Single Screw Snack Extruder for Puffed Food Processing

Product introduction of Single Screw Snack Extruder

The single screw snack extruder is an efficient food processing machine designed for manufacturing a wide range of crispy puffed snacks from flour, starch, and grain-based ingredients. During operation, materials are continuously conveyed through a sealed extrusion chamber where mechanical shear force and controlled heating transform the raw materials into an expanded texture.

By adjusting molds and processing conditions, the equipment can produce various snack shapes, including curls, spirals, shells, and other customized designs. The integrated extrusion system provides stable pressure, uniform expansion, and consistent product quality.

Equipped with automatic feeding, forming, cutting, and temperature control functions, the machine simplifies operation and improves production efficiency. It is suitable for snack manufacturers looking to produce innovative puffed food products with different flavors, shapes, and textures. The compact structure and reliable performance make it an ideal solution for modern snack processing applications.

Product Overview

Flexible Puffed Snack Processing Solution

This single screw extruder uses extrusion expansion technology to transform flour-based materials into lightweight and crispy snack products.

The machine combines:

• material feeding
• extrusion cooking
• shaping
• cutting
• expansion

in one continuous process.

Different molds can be installed to create various snack shapes, helping manufacturers produce multiple product types from the same processing system.

Working Principle

The raw materials are fed into the extrusion chamber and transported forward by the rotating screw.

During the extrusion process, mechanical pressure, friction, and external heating increase the temperature and pressure inside the barrel. The material gradually becomes a plasticized mass under controlled conditions.

When the material passes through the forming die, the sudden pressure release causes moisture inside the product to expand, creating a porous and crispy snack structure.

The formed snacks are then cut into required shapes and prepared for drying, seasoning, or packaging.
