Product Description
Here are the detailed steps to make puff snack food using a twin - screw extruder: ### 1. Raw material preparation - **Base materials** - **Starches**: Corn starch, potato starch, or tapioca starch are commonly used. They form the structural basis of the puff snack. These starches should be of high quality and free from impurities. - **Flours**: Wheat flour, corn flour, or rice flour can be added. Flours contribute to the taste and texture of the snack. For example, corn flour can enhance the corn - like flavor. - **Protein sources**: Plant proteins such as soy protein isolate or whey protein can be included to increase the nutritional value. They also help in improving the texture and structure of the snack. - **Additives** - **Sugar**: Adds sweetness and can also affect the browning and flavor development during processing. The amount can range from 5 - 15% of the total dry ingredients, depending on the desired taste. - **Salt**: Enhances the flavor. Usually, 1 - 3% of the total dry ingredients is sufficient. - **Flavorings**: Natural or artificial flavorings like cheese powder, barbecue flavor, or fruit flavors can be added to give the snack a specific taste. The amount varies according to the intensity of the flavor required. - **Leavening agents**: Baking powder or sodium bicarbonate can be used to promote the puffing effect. These agents release gases during the extrusion process, causing the snack to expand. ### 2. Mixing the ingredients - Combine the starches, flours, protein sources, sugar, salt, flavorings, and leavening agents in a large mixer. - Gradually add water while mixing. The water content is crucial and typically ranges from 20 - 40% of the total weight of the dry ingredients. Mix until a homogeneous dough - like mixture is formed. The mixture should have a consistency that allows it to be easily fed into the twin - screw extruder. ### 3. Twin - screw extruder setup - **Temperature settings** - **Feed zone**: Set the temperature in the feed zone at around 40 - 60°C. This low temperature helps in the smooth feeding of the mixture into the extruder without premature reactions. - **Compression and mixing zones**: As the materials move through these zones, the temperature gradually increases. Temperatures in these zones can range from 60 - 100°C. The heat in these zones starts to gelatinize the starches and activates the chemical reactions between the ingredients. - **Die zone**: The temperature at the die is set relatively high, usually between 120 - 160°C. This high temperature causes the rapid expansion of the snack as it exits the die, creating the puffing effect. The heat also fully cooks the product. - **Screw speed**: Adjust the screw speed according to the viscosity of the mixture. A screw speed of 100 - 300 revolutions per minute (RPM) is common. A slower speed (100 - 150 RPM) is suitable for a more viscous mixture, ensuring proper mixing and conveying. A faster speed (200 - 300 RPM) can be used for a less viscous mixture to increase the production rate. ### 4. Extrusion process - **Feeding the mixture**: Feed the prepared mixture into the hopper of the twin - screw extruder. The twin - screws rotate, conveying the mixture through the barrel. The screws also apply shear and pressure, which further mix the ingredients and heat them up. - **Extrusion through the die**: The fully cooked and pressurized mixture is extruded through a die at the end of the extruder. The die is designed to give the snack its final shape, such as round, square, or ring - shaped. As the mixture exits the die, the sudden drop in pressure causes the water within the mixture to vaporize rapidly. This vaporization creates steam, which expands the snack and gives it the characteristic puffed texture. - **Cutting**: After extrusion, the continuous extruded product is cut into individual pieces using a cutter attached to the extruder. The cutting speed can be adjusted to control the size of the snack pieces. ### 5. Post - extrusion processing - **Cooling**: Allow the freshly extruded puff snacks to cool at room temperature or in a cooling tunnel. Cooling helps to solidify the structure of the snack and makes it crispy. The cooling time can range from 5 - 15 minutes, depending on the size and thickness of the snacks. - **Coating (optional)**: If desired, the puff snacks can be coated with various substances. For example, they can be dusted with powdered sugar, cheese powder, or a mixture of spices. Coating can be done by spraying or tumbling the snacks in a container with the coating material. - **Packaging**: Once the snacks have cooled and any optional coatings have been applied, package them in appropriate packaging materials, such as plastic bags, boxes, or trays. Ensure proper sealing to maintain the freshness and crunchiness of the puff snacks. ### 6. Quality control - **Appearance inspection**: Check the snacks for uniformity in shape, size, and color. There should be no visible signs of cracking, uneven puffing, or discoloration. - **Texture evaluation**: The snacks should be crispy and have a light, airy texture. They should break easily when bitten into, without being too hard or too brittle. - **Flavor testing**: Taste the snacks to ensure that the flavor is well - balanced and appealing. The flavorings should be evenly distributed, and the overall taste should meet the product specifications. - **Moisture content analysis**: Measure the moisture content of the snacks. The ideal moisture content for puff snacks is usually low, around 2 - 5%. This low moisture content helps to maintain the crispness and shelf - life of the product.
