Continuous Sterilization Systems

Sterilization: Is a treatment that takes more time (around 1min), at a higher temperature. TPC will be reduced below a certain target according to customer or regulation policy.

The sterilization mode can kill all pathogen bacteria but also all forms of aerobic bacteria. In certain case sporulated form of bacteria need to be reduced. However, because the spores are usually very heat resistant, sterilization mode may need more drastic conditions (temperature and time), which may affect visual or organoleptic properties of the product.
Continuous sterilizer can guarantee a significant reduction of TPC (except spore/heat resistant germ content). A 5-log reduction on pathogens (E. Coli, Salmonella) is assured, even with a moderate temperature treatment.
Continuous cycle Steam Sterilizer unit for the sterilization treatment of chilli and other spices, powdered or whole up to 10 mm , without affecting the organoleptic properties and appearance (smell, taste).
After this, the product is immediately subjected to a flow of dry and cool filtered air that allows the product to stabilize.
The final moisture content of the product leaving the fluid bed is mainly a factor resulting from the chosen program.

General process description: The treatment consists in subjecting the product for a short time at a high temperature and pressure steam, so that the product does not reach high temperatures.

CHARACTERISTICS:

a) Sterilizing agent: Steam.
b) Type: continuous cycle.
c) Nominal Production: 1000 kg/hour chilli, in continuous cycle.
d) Steam consumption at 8 kg/cm2 : 400 kg/hour approximately.

Continuous Sterilization process relies on:

1) Steam sterilization, controlling time and temperature due to a first in, first out conveying system.
2) Homogeneous and gentle mixing of the product to get the most efficient treatment.
3) No condensation flash cooling system provides a thermal shock to the microbes, a good stabilization of the product, and a safe packaging operation.
