Washing food industry production line

automaticPLC-controlled

Overview
We specialize in manufacturing food-grade CMC cellulose production lines. We provide formulation support, plant layout, and installation and commissioning services to help you produce high-transparency, high-viscosity, gel-free CMC suitable for food applications.

Product Details
Our equipment meets requirements for producing food-grade CMC regarding material purity, reaction uniformity, and solvent recovery. Key equipment includes food-grade Sigma mixers and vacuum drying systems. We recently supported a client in Uzbekistan to establish a food-grade CMC production line.

Food-grade CMC Cellulose Production Process

• Alkaliization stage: Cellulose and liquid alkali are thoroughly mixed in a specialized Sigma mixer to form alkali cellulose.
• Etherification stage: Monochloroacetic acid is added and a controlled substitution reaction is performed under precise temperature control.
• Washing and Neutralization: Multiple washes with an alcohol solution remove sodium chloride byproduct, achieving product purity >99.5%.
• Drying and Pulverizing: Material is dried (vacuum/low temperature) and pulverized to target mesh size.

Food-grade CMC Cellulose Production Line Equipment Configuration
Equipment | Food-grade Dedicated Configuration | Purpose
Sigma mixer | SS304/316, mirror polished | Prevent metal contamination and ensure uniform alkaliization
Vacuum rake dryer | Jacketed heating / high vacuum system | Low-temperature rapid drying to protect cellulose molecular chains
Alcohol recovery tower | Multi-stage condensation / packed distillation | Improve solvent recovery rate (>95%) and reduce production cost
Automatic packaging scale | Cleanroom design / metal detector | Ensure finished product hygiene and prevent foreign matter contamination

Turnkey Project
We offer complete food-grade production solutions:

• Plant planning: Process layout design that meets cleanroom standards.
• Installation and commissioning: On-site engineer guidance to align equipment and process formulation.
• Technical training: Operational tutorials covering raw material selection, formula ratios, and finished-product testing.
• After-sales support: 24/7 online support and spare-parts inventory to ensure uninterrupted operation.

Why Choose Our Food-grade CMC Cellulose Production Line?

• Superior substitution uniformity (DS control) using a high-torque Z-shaped agitator with precisely controlled 2 mm gaps for even fiber–reagent contact and gel-free, transparent product.
• Strict food-hygiene construction: all product-contact parts in SS304/316; shaft seals with food-grade PTFE packing or mechanical seals to prevent lubricant leakage and heavy-metal contamination.
• Closed-loop solvent recovery: high-efficiency condensation and recovery to capture ethanol vapor, reduce VOC emissions and solvent costs.
• Intelligent control (PLC/DCS): fully automatic control of alkalization temperature and etherification addition rate for consistent batch-to-batch quality.
