Product catalog summary
Introduction
The document discusses the Ventilex continuous steam sterilization system, which is used for decontaminating spices, herbs, seeds, and nuts. This method is highlighted as a natural and effective way to eliminate bacteria and pathogens without leaving chemical residues.

Steam Sterilization Benefits
Steam sterilization is presented as a natural, renewable process that is globally accepted as safe. It offers continuous decontamination with typical 5 log reductions in bacteria and pathogens. The high-temperature, short-time processing (HTST) protects the taste, texture, and color of the products while minimizing the loss of volatile oils.

Technologies Offered
Ventilex offers two main technologies: steam sterilizers and steam pasteurizers. Sterilizers operate in closed pressure vessels at up to 3 bar, while pasteurizers work at atmospheric pressure with super-heated steam. The choice of technology depends on the product size and type of pathogens to be eliminated.

Process Description
The Ventilex system uses a continuous inflow of high-pressure steam to eliminate microorganisms while preserving the organoleptic characteristics of the products. The process involves feeding and discharging the product through a self-cleaning pressure rotary valve into an autoclave, where a shaking table transports the product through a steam-pressurized chamber.

System Features
The system features minimal operator intervention with automated controls, data logging, and PLC instrumentation for repeatability and traceability. It includes an automatic sanitary clean-in-place design and is recipe-based for processing multiple products. The system is designed for hygienic operation with low energy consumption and maintenance costs.

Applications
The system can process a variety of products, including chili powders, whole and ground pepper, paprika, garlic, cloves, and other spices and herbs. It is effective in deactivating enzymes like amylase and lipase, which cannot be achieved with irradiation or ethylene oxide treatment.

Conclusion
The Ventilex continuous steam sterilization system is a modern, hygienic, and chemical-free method for decontaminating spices, herbs, seeds, and nuts, ensuring product safety while maintaining natural qualities.

Steam Decontamination of Spices & Herbs, Nuts & Seeds-1

CONTINUOUS STEAM DECONTAMINATION OF SPICES & HERBS, SEEDS AND NUTS Spices, herbs, seeds and nuts and dehydrated vegetable substances bring a world of flavours, aromas and colours to food. The potential for pathogens like salmonella, yeasts, moulds, enterobacteraceae and sporeformers to get into the food supply has resulted in the trend towards more stringent Good Agricultural Practices and regulations. Spices, herbs are sourced worldwide and they may be heavily contaminated from the soil where they were grown and harvested. These microbes often remain after local processing due to simple treatments and processing at low temperatures. If left untreated, these products may encounter continued microbial growth that can easily lead to spoilage and consumer health issues. There are many commonly used methods to decontaminate natural products, such as ethylene oxide and irradiation but most have been or will soon be restricted due to their potential health risks and adverse consumer acceptance. Ventilex Steam Sterilization Benefits: A natural, renewable process that utilizes steam and is accepted worldwide as safe and wholesome Continuous decontamination of bacteria and pathogens – 5 log kills are typical High-temperature, short-time processing (HTST) which protects the taste, texture, and color of the product and a minimal loss of volatile oil Very gentle for leavy products Fluid bed sterilization of spices & herbs Ventilex continuous steam sterilization: Natural elimination of bacteria The use of steam is ideal as it is natural, inexpensive and can be produced in an unlimited supply. It is a natural “organic” process that does not leave behind any chemical residue or create toxins. Steam pasteurization / sterilization systems are the most effective “natural” method for reducing or eliminating bacteria, pathogens, and other food-borne causes of sickness. Effective steam treatment will eliminate listeria, salmonella, E. Coli, and a variety of other bacteria and pathogens. As a result, many of the world’s largest spice, herb and nut processing companies have selected Ventilex Continuous Steam Sterilizers/Pasteurizers. More than 100 systems have been supplied worldwide.

Steam Decontamination of Spices & Herbs, Nuts & Seeds-3

How Does Ventilex Steam Decontamination Work? The process works by feeding and discharging the product through a self-cleaning pressure rotary valve that isolates an autoclave from the ambient room. Inside this autoclave, a shaking table transports product through a steam-pressurized chamber at a specific speed and creates a thin layer of product. Condensation builds on the product surface and this imparts high energy into the surface of the product. This kills unwanted bacteria and pathogens. The time, pressure and steam temperature within the chamber is tightly controlled – just the minimum...
