Benchtop autoclaves with pressure support for food research

TERRA Food-Tech® autoclaves have been designed to cook, pasteurize or sterilize packaged foods at temperatures between 50 and 130ºC using saturated steam generated by the heating elements mounted inside the sterilization chamber. The temperature is regulated by chamber probe or by the F₀/P₀ values by means of a core probe placed inside a reference sample. This allows a perfect control of the process while preserving the organoleptic properties and minimizing possible changes in the nutritional values of the final product. Choose your model from a wide range of chamber volumes, either in vertical or benchtop configuration. In addition, all units can be supplied with different accessories for specific applications.

The CFS-H Series autoclaves are used in a wide variety of applications and sectors such as scientific research in universities, product development in the food industry, research in the packaging industry, and for training purposes at trade schools.

CFS H detalle1

State-of-the-art technology for research in the food and packaging industry

High productivity for research centers and industry. It has a pressure support system that can be adjusted up to 2.1 Barg to avoid damaging or breaking the containers. Regulation by F₀ and by P₀, with additional recording of Σ%F₀ and Σ%P₀.

Flexibility in the control of each process

A 5'' touchscreen controller offers up to 50 different customizable programs. For advanced users and research professionals, all units can be programmed with up to 11 independently adjustable temperature segments for temperature, time and pressure.

A. Heating phase
In this initial step, the heating elements mounted at the bottom of the sterilization chamber heat up dramatically, transferring energy to the water to produce steam.
B. Sterilization phase
At 100ºC sterilization begins and the autoclave starts to calculate the F₀ reached in real time. Upon reaching the target processing temperature, the temperature is maintained for the duration of this phase until the reference sample reaches the target F₀. In some acidic products, sterilization occurs at temperatures below 100ºC. This crucial step is controlled by two PT-100 Class A temperature probes located on the wall of the sterilization chamber and inside the reference sample.
C. Cooling phase
When the target F₀ value is reached, the fast cooling phase begins, with water being rapidly injected into the chamber while the pressure support is activated. Pressure control is essential to avoid damage or breakage of the containers due to the thermal shock caused by the injection of cold water into the chamber. The number and duration of water chamber fillings can be adjusted. The temperature at which the door can be opened can also be adjusted.
