The Ventilex Continuous Steam Sterilizing System is ideal for H.T.S.T. (High Temperature / Short Time) decontamination of Spices, Herbs, Seeds, and other Organic Materials. The H.T.S.T. process exposes contaminated material to saturated steam for a very short time, then dries and cools the product.
This is a simple idea, but is one of the most practical and effective methods for treating products in this industry. The continuous system treats powders next to whole spices, which is a unique feature of the Ventilex system.
The process works by feeding the product through a high-pressure rotary valve that isolates an autoclave from the ambient room. Inside this autoclave, a shaking table transports product to a steam-pressurized chamber. Condensation builds on the product surface and the controlled heat creates the appropriate amount of steam. This kills unwanted bacteria and pathogens. After it has been treated, the product is discharged through a secondary rotary valve, into the fluid bed dryer. Here, the condensed moisture is driven off and the product is returned to the original moisture level or dried to a new moisture level.
Benefits of the Ventilex Steam Sterilization system include:
A natural, renewable process that utilizes steam
Continuous sterilization of bacteria and pathogens
Deactivation of enzymes
Sanitary Clean-in-Place (CIP) design
Repeatable and verifiable process
Our system can be used to process chili powders, whole and ground pepper, paprika, garlic, cloves, and a variety of herbs, seeds, and other spices. If your process requires exact treatment times, the Ventilex Steam Sterilization System is the answer.
The use of steam is ideal as it is natural, non-toxic, cheap and in unlimited supply. Steam offers many advantages including, the fastest possible way of heating product to an exact preset temperature, condensation on the product and provides the water activity required for effective sterilization while protecting the product against overheating and burning. The steam condensed on the product also enables flash cooling of the product when it leaves the sterilizer and is returned to pretreatment specifications in an integrated Ventilex Dryer / Cooler system.
The presence of pathogens including salmonella, yeasts, moulds, enterobacteraceae and sporeformers can never be excluded despite frequent checking and is the main reason for the requirement of sterilization. Frequently, raw materials are heavily contaminated from the soil and these microbes often remain after processing due to simple treatments and processing at low temperatures in their countries of origin. If left untreated, these products can provide perfect conditions for continued growth of the microbes which can lead to spoilage and customer health issues.
Some commonly used decontamination methods, such as ethylene oxide and irradiation may be restricted due to health risk and adverse consumer acceptance. Aside from health risks, food technological aspects such as the inactivation of enzymes, e.g. amylase and lipase, cannot be solved by irradiation or ethylene oxide treatment. These enzymes have been shown to cause a breakdown of fat and starch components in sauces, salads and many ready-made meals.
As a result, many of the world’s largest spice processing companies have selected the Ventilex Continuous Steam Sterilizer. With the Ventilex system, you get the continuous “inflow” application of saturated, high pressure steam that provides the ideal environment for the inactivation of enzymes and the elimination of undesired micro-organisms while causing minimum harm to the organoleptic characteristics of spices and herbs.
Ventilex, founded in 1965 in the Netherlands, has earned a worldwide reputation in providing tailored drying solutions in many industrial branches for example pharmaceuticals, food and dairy, chemicals, energy, biomass and minerals industries.
Ventilex is one of the biggest global players in industrial product drying and is known for providing the highest quality, greatest energy saving equipment of its type in the world.
With offices in The Netherlands and in the USA we have been marketing for more than 50 years:
Fluid bed drying and cooling technology
Belt dryer technology
In our own extended laboratory we are able to provide our customers with an optimal drying solution. We test the products here to match the drying solution to the customer’s production process.
We can provide the complete project if required, from testing and engineering to implementation, start-up and after sales. We often supply the installation complete with air input and output and the PLC controls.
We are well known for our reliable systems, designed to withstand decades of 24/7 operation with minimal maintenance. Ventilex has all the disciplines on board to make your industrial drying a smooth and smart process.
