5 Steam Sterilization of Spices and Herbs High Pressure Steam Technology: HTST : High Temperature / Short Time Log 5 kill typical for reducing pathogens from either whole or ground spices Proven European Technology Three Standard Sizes

6 Typical Microbiological Quality of Products Treated With the Ventilex Continuous HTST System: (specific examples to follow) + Total count <10,000 often <1,000 + Enterobacteriaceae: <10/gram (n.d.) + Salmonella absent + Yeasts and moulds <100/gram (n.d.) + Bacilles Cereus <100/gram (n.d.) + Clostridium Perfringers: <100/gram (n.d.) + Stafylococcus Aureus: <100/gram (n.d.) Success with difficult leaf spices like mayoram (oregano) and basil n.d. = not detectable

10 Steam Pasteurization System

11 Principles of Ventilex Technology for Steam Sterilization & Pasteurization:

12 Steam Decontamination High pressure steam is introduced for a specific time period typical: 20 to 50 seconds time within 4% 107 C to 123 C (224 F to 253 F) 1.3 to 3 bar Product is conveyed in a thin layer, exposing all surfaces to the steam Hot condensate forms on product- perfect distribution Correct temperature and time provides desired kill of pathogens Flash cooling down to 55 C (132 F) within 30 seconds Product immediately dried and cooled to the desired moisture in the fluid bed dryer/cooler

25 Ventilex/Trecom Automated Control System Fully Pre-programmed Operation Continuous operation of system - accurately controlled Automated controls with data logging/acquisition

26 MCC + PLC

27 MCC + PLC

28 Advantage MCC + PLC: Operator only needs to select the right recipe The set points are always the same DATA Logging = Traceability, Validation

29 Advantage Ventilex System No residual chemicals No special labels on product Low energy use Minimal operator intervention automated controls Can be operated efficiently over a wide range of production rates Will not degrade product and very gentle for leafy products
