Biostimulant Equipment

From raw seaweed to ready-to-use biostimulant preparations.

Containerized Modular Seaweed Extraction by Sirputis

Our modular system transforms freshly harvested seaweed biomass into high-value biostimulant ingredients, supporting the green transition in agriculture and related industries.

We design and manufacture equipment and modular processing systems that cover the entire technological chain — from raw seaweed to finished biostimulant products.

Process capabilities

  • Handles wet or semi-dry seaweed (including Sargassum, Alaria, Kappaphycus, Saccharina, Giant kelp, and others)

  • Input: 0.75–2.0 t/h of wet biomass

  • Operation time: 8–20 hours per day

  • Output:

    • Stabilized liquid biostimulant – 500–2,000 l/h

    • Dried granules/powder – 8–15% moisture

    • Key advantages

  • Sirputis mechanical cell disruption technology releases valuable alginate oligosaccharides, fucoidan, laminarin, and polyphenols from seaweed cells

  • Rapid deployment: fully operational within 6–8 months, compared to 1–1.5 years for conventional plants

  • Scalable capacity: easily expandable in 0.5 t/h increments using standardized modules — no redesign or downtime required

  • Compact footprint: 400–700 m²

  • Installed power: ~200 kW

High-Level Process Overview

The process begins with fresh seaweed biomass, which is mechanically disintegrated in a water-based slurry.
Valuable bioactive compounds are released and separated into a liquid extract, while the remaining fibrous pulp is pressed and optionally dried for further use.

Balanced Technical & Economic Summary

General assumptions

Parameter Unit Value

Pressing / fractionation balance (per hour)

Parameter Unit Value
DM retained in pressed cake % of input DM 78% (adjusted from 79% to balance)
Dry matter to cake kg/h 312
Pressed cake dry solids (DS) % 26

Liquid phase output kg/h 2,800
Dry matter to liquid phase kg/h 88
Solids concentration in liquid % (m/m) ≈3.14% (88/2,800)

Balance check (per hour):

Input = 4,000 kg (400 kg DM + 3,600 kg water)
Output = 1,200 kg cake (312 kg DM + 888 kg water) + 2,800 kg liquid (88 kg DM + 2,712 kg water) = 4,000 kg
DM in = 400 kg; DM out = 312 + 88 = 400 kg
