After several years of development, the SHAKA™ technology is introduced to the market.

STERIFLOW SAS recently signed a manufacturing licence agreement with Zinetec, the inventor of this revolutionary system and will have the first laboratory-scale SHAKA™ retort ready by March 2006.

During processing time, the containers in the retort are vigorously shaken at a frequency of 100 to 200 cycles per minute. The agitation of the product is achieved through a horizontal movement of the baskets. This product agitation allows a rapid acceleration of heat penetration. Cycle times are reduced by a factor of 5 to10 compared to standard retorts.

The reduced process time has a highly positive impact on the quality of the product (colour, taste, vitamin preservation...) compared to that usually obtained with static or rotary autoclaves. The SHAKA™ retort can be used with all types of containers available from rigid cans, glass jars and trays to flexible packaging such as pouches. Products such as sauces, soups, babyfood, vegetables or petfood have been positively tested.

In addition, the sharp decrease in cycle times greatly improves the utilisation of the sterilization equipment. From 4 to 5 cycles per hour can be carried out in the SHAKA™ retort.

The development work was made with a prototype based at the CCFRA in Chipping Camden, UK, which was tested by major worldwide packaged food producers.

For the first stage, STERIFLOW SAS is proposing lab-scale SHAKA™ retorts. An industrial-scale SHAKA™ retort will be introduced in the middle of 2006.

Managing Director - F. Jahn & Co. Ltd.

I graduated from Nottingham University in 1975 with a degree in Production Engineering and Production Management.

In 1977, I joined my father at F. Jahn & Co. Ltd., working initially in the After Sales side of the business. I transferred to the Sales Department in 1980, with responsibility for the marketing and sales of the range of canning equipment, HEMA fillers and also retorts from Barriquand STERIFLOW, who had recently appointed F. Jahn as their UK representatives.

Together with my father, then Sales Director, we purchased the company in 1990 from the Chairman and last remaining member of the Jahn family, Charles Jahn. In 1991, I took over the position of Managing Director and from that time have continued to oversee the development of the company and our portfolio of overseas suppliers.
