Pneumatic conveying solution for food-grade calcium carbonate
During the production of food additives, the transportation stage of food-grade calcium carbonate often faces risks such as dust dispersion, material loss, and cross-contamination. Based on years of pneumatic conveying experience, Head Powder has launched a customized food-grade calcium carbonate pneumatic conveying system, optimizing traditional manual feeding methods through fully enclosed pipeline transportation, supporting production cleanliness and material quality from the source.
Customer pain points
Traditional calcium carbonate conveying methods have three prominent problems: First, open handling causes large amounts of dust to disperse, polluting the workshop environment and endangering operator health; Second, materials are prone to moisture, clumping, or contamination during transportation, affecting food-grade standards; Third, manual feeding efficiency is low and accurate measurement is difficult, resulting in poor batch stability. Therefore, companies urgently need an automated solution that can deliver food while being sealed while meeting food hygiene requirements.
Material characteristics

Food-grade calcium carbonate is a white fine powder with a density of about 0.5–0.8 g/cm³, and particle fineness reaching over 325 mesh. This material has average fluidity and easily adheres to the inner wall of pipelines; At the same time, it has strong hygroscopic properties and must be operated in dry, sealed environments. Additionally, as a food additive, it has strict limits on contaminants such as metal foreign matter and lubricating oil intrusion during transportation.
Product Introduction

The Head powder food-grade calcium carbonate pneumatic conveying system uses positive pressure dense phase or dilute phase conveying methods, with customized designs based on customers' site layouts, conveying distances, and production capacity requirements. The core components of the system include a rotary feed valve, delivery pipeline, air supply device, dust separation and collector, and automatic control system. All parts in contact with materials are made of 304 stainless steel or food-grade wear-resistant materials, and are polished to a mirror finish for easy cleaning and no residue.
Product advantages

To address customer pain points, this solution provides the following support: fully enclosed pipeline transportation to reduce dust spillage to trace levels, and workshop air dust concentration meets GMP standards; Equipped with iron remover and screening devices, helping to remove metal impurities; The automated control system enables relatively accurate feeding and remote monitoring, reducing manual intervention; The pipeline interior uses a smooth runner design to reduce the risk of material residue and blockage, supporting production continuity.
