1. Product Overview
This complete Edible Rice Straw Production Line is a fully integrated, turnkey solution designed for the mass manufacturing of biodegradable, food-safe edible drinking straws from rice flour, tapioca starch, and other plant-based raw materials. Built for efficiency, consistency, and scalability, it transforms simple grain ingredients into high-quality, zero-plastic drinking straws that meet the growing global demand for eco-friendly alternatives to single-use plastics.
The line is engineered to handle the entire production workflow—from raw material mixing and extrusion to cutting, drying, sorting, and packaging—delivering a streamlined, low-labor process that ensures uniform straw quality, consistent dimensions, and long shelf life. It is ideal for small to medium-sized food manufacturers, catering suppliers, and sustainable product brands looking to enter the fast-growing biodegradable straw market.
2. Key Features
- Turnkey & Fully Integrated System: Combines all necessary equipment (mixer, twin-screw extruder, cutter, multi-layer dryer, sorter, and packaging unit) into one seamless production line, eliminating the need for separate, uncoordinated machinery.
- Food-Grade & Hygienic Design: Constructed from 304 stainless steel for all product-contact parts, with easy-to-clean surfaces and food-safe seals to meet international food safety standards (FDA, CE, ISO).
- High Efficiency & Low Energy Consumption: Optimized twin-screw extrusion technology ensures uniform dough processing with minimal waste, while energy-efficient dryers reduce operational costs without compromising straw durability.
- Customizable Production: Supports adjustable straw diameters (6–12mm), lengths (150–250mm), and colors/flavors (natural rice, green vegetable-infused, or custom blends) to meet diverse market needs (coffee shops, bubble tea, restaurants, events).
- Durable, Water-Resistant Straw Output: Advanced high-temperature drying and curing technology produces straws that remain firm in both hot and cold beverages for 2–6 hours, with no sogginess or off-flavors.
- Low Labor & Easy Operation: Automated controls for mixing, extrusion, cutting, and drying reduce manual labor requirements, with a user-friendly HMI (Human-Machine Interface) for easy parameter adjustment and monitoring.
- 100% Biodegradable & Compostable Output: Produces straws that break down naturally in soil within months, leaving no microplastics, aligning with global sustainability regulations and eco-conscious consumer demands.
3. Production Workflow
- Raw Material Preparation & Mixing:
Rice flour, tapioca starch, water, and optional natural colorants/flavors are blended in a high-speed mixer to form a homogeneous, moisture-controlled dough with the ideal consistency for extrusion.
- Single-Screw Extrusion & Forming:
The dough is fed into the single-screw extruder, where it is kneaded, heated, and pressurized. It is then forced through a custom-designed die head to form a continuous hollow tube (the raw straw).
- Online Cutting:
A precision rotating cutter at the extruder outlet automatically cuts the continuous straw tube into pre-set lengths, ensuring uniform size across all products.
- Pre-Drying & Shaping:
Freshly cut straws pass through a low-temperature pre-dryer to remove surface moisture, preventing sticking and preserving their tubular shape.
- High-Temperature Drying & Curing:
Straws move through a multi-layer tunnel dryer at controlled temperatures (80–120°C) to remove internal moisture, gelatinize starch molecules, and develop water resistance and structural rigidity.
- Sorting & Quality Control:
A sorting unit removes broken, misshapen, or defective straws, ensuring only high-quality products proceed to packaging.
- Packaging:
Finished straws are automatically counted and packed into bulk bags, cartons, or custom retail packaging, ready for distribution.
