Pneumatic conveying solution for food-grade calcium carbonate
In the production and processing of food additives, calcium carbonate serves as an important nutritional fortifier and anti-caking agent, and the cleanliness and stability of its transport process directly affect the quality of the final product. Traditional mechanical conveying methods easily cause dust leakage, material clumping, cross-contamination, and are difficult to meet the strict hygiene standards required for food-grade production. Head Powder addresses these industry pain points by launching a customized food-grade calcium carbonate pneumatic conveying system to help customers achieve efficient, sealed, and low-loss material flow.
Material Characteristic Analysis

Food-grade calcium carbonate is usually a white powder or fine granules, with particle sizes ranging from 10~50 microns. It features moderate density, average flowability, and is prone to moisture absorption and caking. At the same time, as a food additive, it imposes strict restrictions on metal foreign matter and microbial contamination during transportation, requiring the entire pipeline system inner wall to be smooth, without dead corners, easy to clean, and the medium to be transported must meet food hygiene standards.
Product Introduction

Head Powder's food-grade calcium carbonate pneumatic conveying system uses either positive pressure dense phase or negative pressure dilute phase conveying methods, with the entire process completed within a sealed pipeline. The system consists of a feeding device, conveying pipelines, air source equipment, dust separation device, and automation control unit. Depending on material characteristics and customer requirements, stainless steel 304/316L pipes, food-grade sealing gaskets, and oil-free air compressors can be selected, helping to transport media cleanly and without pollution. The entire conveying process is controlled by PLC, allowing for more accurate adjustment of conveying speed and material-gas ratio to prevent material damage or pipeline blockages.
Product advantages

To address customers' pain points such as dust pollution, inefficiency, and cleaning difficulties, Head Powder offers the following solutions:
- Fully sealed and dust-free transport: The system adopts a sealed pipeline design to prevent material contact with the external environment, effectively controlling dust dispersion, improving the working environment, and reducing raw material waste.
- Customized piping and fittings: Personalize pipeline routing based on the customer's site layout and conveying distance; The inner wall is polished to reduce material residue and facilitate cleaning and verification.
- Intelligent control and monitoring: Equipped with pressure and flow sensors and a touchscreen control system, it monitors conveying status in real time, automatically adjusts parameters, reduces manual operation risks, and improves operational stability.
- Food-grade compliant design: All parts that come into contact with materials are made of food-grade stainless steel and seals, meeting HACCP and GMP requirements to prevent contamination by metal ions or foreign objects.
Head Powder has long been deeply involved in the pneumatic conveying field and has extensive experience in transporting food-grade materials. From solution design to equipment delivery, we provide one-stop customized services to help food companies improve production efficiency while meeting increasingly stringent hygiene and environmental standards.
