Through heat treating growing substrates (and other materials) using the FlowSteama Rova, commercial nurseries and greenhouses are able to significantly improve profits of their growing operations while reducing ongoing costs.

Creating clean growing media, reuable over multiple growing cycles ✔; Growing extra crop per season (higher yields compared to virgin substrate) ✔; Improving nutrient uptake ✔; Reducing losses from diseased crop ✔; Improving in-house hygiene control ✔; Lowering virgin substrate import costs & reduced CO₂ ✔; Reusing existing growing substrates; becoming resource-efficient ✔; Reducing disposal cost of used substrate ✔; Avoiding use of banned, health hazardous chemicals ✔; Meeting increasingly higher environmental standards from supermarkets & customers ✔

Customers owning the FlowSteama Rova enjoy the benefits of mobile in-vessel sterilizing equipment that can be easily relocated on-site between stockpiles of used substrates and topsoil’s, minimising handling costs of moving material around large commercial sites.

The Rova heat treatment unit can be moved between adjacent sites, enabling smaller commercial growers to share a single sterilisation system. Recycling yards often also have various organic fractions on different parts of the site; the Rova enables these stockpiles to be cleaned in-situ from bacteria, fungi and weed seeds. Coupled with a mobile, low-pressure super-heated steam generator, suitable water supply and fuel source, Rova can be located adjacent to stockpiles for hours, days or longer, before moving on to sterilise contaminated material elsewhere.

Wherever there are topsoils contaminated with weed seeds, or substrates contaminated with pathogens, the Rova can be transported there inside a 12 metre ISO shipping container. Minimal assembly is required to get the mobile process up and running, and commissioning is led by our experienced steam-team.

1. The "dirty-side" in-feed hopper is loaded using a telehandler, tractor loader or conveyor, depending on clients requirements.
2. Substrate is automatically distributed along the sterilising bed, mixing and tumbling to give maximum steam penetration into the material. Sterilisation occurs in a controlled, insulated in-vessel environment where material temperature and sterilisation residency time are user-controlled via the HMI.
3. The unloading auger automatically empties the sterilised substrate from the Rova onto a suitable conveyor for stockpiling the clean material away from the contaminated input material.
4. The suitably-cleaned, valuable sterilised output material can be sold or used in-house in commercial growing operations; creating added value for the owners of the FlowSteama equipment.

FlowSteama Rova is equipped with a modern SteamStation™ HMI touchscreen together with smart, self-protecting control systems, providing safe shutdown in the rare event, for example, of oil over-temperature situations. Sensors provide operators with real-time key data to enable optimised efficiency of output and material sterilisation.

Optional equipment is available for logging, reporting and evidencing material temperature and residency time, enabling clients to demonstrate to local certification bodies that the sterilizing process has been completed to specified parameters. This is particularly important when onward selling composts, soils and substrates, and is particularly relevant when the material is crossing borders, to prevent international spread of disease and invasive species.

While there are regional differences in the hygiene standards for organics and compost quality, there is a growing understanding of the need to avoid cross-border contamination, reduce the risks of invasive species transfer, and ensure high hygiene standards for food growing substrates.

Output material parameters of the FlowSteama Rova are optimised to comply with your local certification standards for composts, growing media substrates, topsoil and more. Take control of your process with Stronga substrate steaming and the new steam age.

Increasing public health concern related to excessive chemical and pesticide use, plus increasing awareness of residual effects of chemical use in soil biomes and upwards through the food chain, has led to a new era of clean-steam renaissance. FlowSteama enables a chemical-free, safe and efficient solution for commercial-scale food production, and the benefits are substantial.

Reduced harmful chemical use ✔; Avoid chemical residual & build-up effects ✔; Clean steam future for substrates, topsoils & food production ✔; Improved long-term public health ✔; Improved soil ecosystem & environment ✔; Increased food crop production & reduced losses from disease ✔
