SIRV
Classification
- Sterilization
- Food and Beverage
- Pharma and Nutraceutical
"SIRV” system is designed to sterilize grain materials only, resulting in a compact, cost-efficient, and low-maintenance system. This system was developed by taking advantage of the features of the high-pressure rotary valve, in which the material is continuously fed and instantaneously sterilized (3 to 10 seconds) like if it was processed by a continuous rotary autoclave. Standard system includes a vibrating dryer/cooler suitable
for grain materials.
for grain materials.
Features
- Minimal System Configuration
The key component is the in-house designed high-pressure rotary valve. Due to that the system is compact, cost-efficient and requires minimal maintenance. - Excellent Sterilization Effect
Superheated steam with big thermal energy is directly blown into the pockets of the rotary valve to kill E coli, viable cells and thermoduric cells (sterilization time: 3 to 10 seconds depending on feed rate and material properties). - Wide working range and easy to use
Pressure, temperature and heating time can be set as desired, making SIRV suitable for sterilization of a wide variety of grain materials. - Easy Cleaning
The pneumatic pipe can be easily cleaned by flushing water from the material feeder and dried with the inline heater.
EXAMPLE OF APPLICATIONS
Spices/cereals/seeds and other grain materials

Capacities and Utilities
| Model | Capacity | Utilities | |||
|---|---|---|---|---|---|
| Capacity (kg/hr) | Max. pressure (MPaG) | Sterilization time (sec.) | Steam (kg/hr) | Power (kW) | |
| SIRV-20 | 200 | 0.55 | 3 to 12 | 80 | 30 |
| SIRV-50 | 500 | 0.55 | 3 to 12 | 200 | 50 |

※Capacities are based on grains with a bulk density of 0.5kg/L and may change depending on material properties.
※Steam consumption depends on the material being processed as well as operation conditions.
※Steam consumption value is for stable operation. In equipment startup and cleaning, approx. 5X of steam may be required.
※Cleaning water is needed (equipment cleaning process).
