00IN-HOUSE STERILIZATION

Food Sterilization Unit

Protect your contracts, not just your product.

When a buyer rejects a batch on a microbial spec, or a market closes to chemically treated goods, the bill lands on you: lost contracts, returned shipments, broken trust. A BioSteam unit puts a validated kill step in your own hands, using saturated steam under vacuum to hit your microbial targets while protecting flavor, color and active compounds. No chemicals, no residues, full traceability, on your site and on your schedule.

Pharma-grade documentation rigor. Adapted for dry food at industrial scale.

01The steam cycle

Four controlled phases. One dry, validated batch.

Vacuum, saturated steam, time and temperature work as one instrumented process. Watch the cycle run, or click a phase to inspect it.

Schematic illustration. Temperature, hold time and pressure are set for each product.

Hover the monitor to pause it, or click a phase to jump to it.

01

No cross-contamination

Product stays in its own bag throughout the batch process.

02

One program per product

Time, temperature and vacuum are configured to the product, not forced through a fixed line.

03

Static product

No mechanical movement means less breakage, dust and quality loss.

04

Batch traceability

itech records the process conditions and makes every batch auditable.

05

No chemical residue

Saturated steam delivers the treatment without chemical sterilants.

04Next step

Bring your product to the cycle.

Share the product, volume and target reduction. We will map the right program and the evidence needed to validate it.
