Introduction

In seaweed and microalgae processing, the effective mixing, homogenization, holding, and conditioning of biomass slurries, extract solutions, and intermediate products between unit operations is critical to maintaining product quality, process consistency, and downstream efficiency. Kerone’s Mixing and Storage Tanks for Seaweed Processing are purpose-engineered vessels designed to handle the specific challenges of marine algal biomass — including its high viscosity, corrosive salt content, tendency for biological degradation during holding, and the wide range of temperature and pH conditions encountered in different processing steps. From receiving and buffer tanks for fresh seaweed slurries, to conditioning tanks for post-blanching material, extraction vessels for polysaccharide solubilization, and formulation tanks for biostimulant and cosmetic intermediate production, Kerone’s tanks are precision-fabricated stainless steel vessels with optimized agitation, temperature control, and hygienic design for every application in the seaweed processing chain.

Why Choose Kerone Mixing and Storage Tank for Seaweed Processing

Kerone’s Mixing and Storage Tanks are engineered with a thorough understanding of the complex rheological behavior of seaweed slurries and extracts, which can exhibit highly non-Newtonian, pseudoplastic, or thixotropic flow behavior depending on the polysaccharide concentration and temperature. Kerone’s agitator designs are specifically selected and sized to handle these challenging fluid properties — ensuring uniform mixing without excessive shear that could degrade sensitive bioactives or cause foaming — using swept-blade, anchor, gate, or helical ribbon agitator configurations based on the application. All tanks are fabricated from SS316L stainless steel with electro-polished or bead-blast internal surfaces, full drain and cleanability, and CIP spray ball or jet cleaning systems for the highest hygiene standards. Temperature control is provided by integrated jacket, half-pipe coil, or internal heating/cooling elements, allowing precise thermal management from 4°C (cold storage) to 95°C (hot extraction).

Types and Features of Mixing and Storage Tank for Seaweed Processing

Kerone’s seaweed processing tanks range from compact 500-liter mixing vessels to large 50,000+ liter storage and buffer tanks, in vertical or horizontal configurations with conical, dished, or flat bottom designs based on process requirements. Agitated tanks are available with top-entry, bottom-entry, or side-entry agitators, with variable-speed drives for adjustable mixing intensity. Temperature-controlled tanks include full or half-pipe jacketing with glycol cooling or steam heating, along with insulated outer shells for energy efficiency. All tanks include hygienic manholes, spray balls or jet cleaners for CIP, sight glasses, sample valves, temperature and level instrumentation, and pressure-relief valves. Optional features include inline homogenizers, recirculation pumps with strainers, pH monitoring and dosing systems, dissolved oxygen monitoring, and sanitary butterfly or diaphragm valves throughout.

Applications of Mixing and Storage Tank for Seaweed Processing

Kerone’s Mixing and Storage Tanks for Seaweed Processing are extensively used across multiple applications in the seaweed and microalgae processing industry.
Typical applications include:
    • Fresh seaweed receiving and buffer tanks — holding and conditioning freshly harvested seaweed slurries before primary processing steps
    • Blanching and conditioning vessels — holding seaweed at controlled temperature and time for enzyme inactivation and iodine reduction
    • Polysaccharide extraction tanks — hot water or alkali extraction of alginate, carrageenan, and agar from pre-treated seaweed
    • Biostimulant formulation tanks — blending and conditioning liquid seaweed extract with additives for biostimulant fertilizer production
    • Microalgae cultivation and harvesting — open raceway pond supplements and closed photobioreactor harvest concentration vessels
    • Cosmetic and pharmaceutical intermediate storage — holding and mixing seaweed extract intermediates for cosmetic and nutraceutical formulation
Reliable, hygienic, and precisely controlled mixing and storage is a fundamental enabling capability throughout the seaweed processing chain. Kerone’s Mixing and Storage Tanks are purpose-engineered for the specific demands of marine algal biomass processing, providing the combination of materials quality, agitation performance, thermal control, and hygienic design that seaweed processors need to maintain product integrity across every step of the process. With a Kerone tank at every critical point in your processing line, you can be confident that your product quality is protected from receipt to dispatch.
