Inside Revtech: Questions About Our Industrial Solutions
What is the difference between a steam sterilizer and a steam pasteurizer?
In practice, the two terms overlap. “Steam sterilization” is the industry’s common name for the steam decontamination of spices and dried herbs — even though, strictly speaking, it is a high-level microbial reduction rather than absolute sterilization. Both a steam pasteurizer and a steam sterilizer use a controlled amount of steam to significantly lower the microbial load — pathogens such as Salmonella and E. coli, as well as total viable count, yeasts and molds. The main difference is the terminology and the target product: “pasteurization” is the term used for nuts, seeds and grains, while “sterilization” is used for spices and herbs, where buyers expect a deeper reduction of total flora. In both cases, the same Revtech tower reaches validated microbial targets using precise steam, temperature and residence time, while preserving the product’s color, aroma and flavor.
Can the same unit be used for roasting?
Yes! The Revtech heat treatment tower is versatile. The same continuous unit can steam-sterilize and, by adjusting temperature and residence time, also roast or toast the product in a single pass. It doubles as a continuous spice and seed roaster, for roasted cumin, coriander and fennel seeds as well as sesame seeds. This lets processors run several processes, pasteurization and roasting, on one electric line.
What are the main advantages of a Revtech steam sterilizer compared to other systems on the market?
The Revtech steam sterilizer is a 100% electric, continuous process — a clean, chemical-free alternative to ethylene oxide (ETO) and irradiation. Its precisely controlled steam, temperature and residence time deliver a validated, repeatable microbial reduction while preserving what matters most in spices and herbs: color, aroma and essential oils. The enclosed, vibratory REVE design treats fragile products gently and evenly, prevents recontamination, and handles high throughput on a compact footprint.
