SARP SOLUTIONS
Thermal processing lines for Doypack and Pouch
From concept to global support: engineering built around you.
We do not adapt your work to our machines: we design technology so that it integrates into your world.
CONNECTED ENGINEERING, 100% CUSTOM-MADE
Every SARP system is completely customized. Our lines automatically connect different work areas, reducing waiting times between production and packaging. Thanks to the flexibility of the belt in all directions and the design with free internal space, we ensure the utmost respect for the integrity of your product.
Thermal Processing in Pouch
We develop custom systems for the thermal processing of food products such as fruit juices, purees, baby food, and sauces packaged in flexible pouches (Doypack, stand-up pouch, spout pouches, cheerpack). Our spiral lines cover the entire thermal processing cycle, from pasteurization to cooling (from +100°C to +4°C), integrating perfectly into your plant to optimize timing and preserve product quality.
Technological advantages
Our strength: Pouch Pasteurization and Cooling
The thermal processing of pouches is based on a two-phase process, designed to guarantee the complete safety of both the contents and the packaging:
Phase one: Heating and Holding
The product and the pouch are heated and maintained at a constant temperature between 95°C and 98°C. This treatment is used to achieve the required P-value, eliminating bacteria even in the most critical points of the primary packaging, such as the folds of the pouch, the spout and the corrugations of the cap. The time and temperature parameters are custom-calculated based on the recipe, the pH, and the product’s fat concentration.
Second phase: Controlled Cooling
The cooling process slows bacterial growth, improving the product’s shelf life. It also prepares the pouch for secondary packaging and prevents thermal shock during the storage phase.
OUR AIR TREATMENT SYSTEM
EFFICIENCY AND ABSOLUTE HYGIENE
Our systems operate entirely through a controlled airflow that envelops every component, including the mechanical gears. This system eliminates the use of water, offering extraordinary advantages for your line
Maximum hygiene and sanitization
The absence of stagnant moisture makes the system perfectly hygienic and easy to clean. Moreover, in the event of the accidental breakage of a package, the air system is not compromised.
Product ready for packaging
At the end of the treatment, the pouches are completely dry and ready to immediately enter the secondary packaging area (cartons and boxes).
Constant temperature and recirculation
The air is heated and continuously recirculated inside the insulated chamber, maintaining the ideal climate throughout the entire cycle.
Minimal maintenance and reduced costs
The air heating system drastically reduces operating costs and maintenance times compared to traditional systems.
DESIGN CHOICE
TUNNEL OR SPIRAL?
The perfect configuration for your space
There is no single solution for pouch processing: the choice between a tunnel or spiral layout depends on the characteristics of the facility and production goals:
We analyze space constraints and internal logistics to recommend the geometric configuration capable of giving you maximum production output.

LINEAR INTEGRATION
When linear precision is needed
It is perfect when the facility mainly extends in length or when the production flow requires a linear and continuous transfer between machines positioned on the same operating level (suitable for medium and low production capacities).
SPACE OPTIMIZATION
When vertical capacity is needed
It is the ideal choice if floor space availability is limited. By making use of the building’s height, it minimizes floor footprint and ensures high production capacity within the same
OPTIMIZATION
The value of energy efficiency and space
SARP technology is designed to deliver heat exchange close to 100% between air and product, minimizing the time needed to reach the desired temperature.
Ground space savings
Vertical development takes advantage of the facility’s height, minimizing the footprint and eliminating costs per square meter.
External air recovery (up to -50% consumption)
By placing coils and evaporators inside the insulated chamber, we optimize energy flow. In addition, thanks to the possibility of integrating an external air recovery system, it is possible to achieve energy savings of up to 50% compared to market standards.
