Video: The new Shaka® 1600 agitation retort

The Allpax 1600 Shaka high-speed agitation retort equals the output of four-basket static retorts because of an up to 90 percent reduction in cycle time. Shaka opens the doors to new products that would typically be difficult to retort and improves the taste and appearance of products now available on the market. Booth # N-3910

Allpax Products, powered by Pro Mach, said today it is now manufacturing the Shaka® 1600 high-speed agitation retorts. These single-basket retorts are the largest capacity Shaka retorts in the world.  With a one-ton capacity, they can equal the output of four-basket static retorts because of an up to 90 percent reduction in cycle time.

“Because of the significantly reduced processing time, Shaka opens the doors to new products that would typically be difficult to retort and improves the taste and appearance of products now on the market,” said Greg Jacob, vice president and general manager, Allpax. “For example when compared to static retorting, the improved taste and appearance difference is like night and day for pasta dishes, soups with particulates, sauces, and many other foods. The first production Shaka retorts were shipped last year and new Shaka retorted products from a major brand are now on the market.”

Jacob said that the dramatically shortened batch times of the Shaka process means less overall heat degradation of the food and this has a profound effect on quality. In many cases low acid, shelf stable foods using the Shaka process can match or exceed the higher echelon of chilled, frozen, and aseptic products, but with an overall lower cost per case and the flexibility of batch retorting.

Shaka retorts are ideal for producing shelf-stable food packaged in cans, glass, semi-rigid, and flexible containers. In a Shaka retort, packaging is loaded in a horizontal orientation to obtain the highest benefit. Unlike other retorts where packaging at the outside or the center of the basket experience different heat profiles, all containers in a Shaka retort experience the same profile which leads to greater consistency in each batch.

Product innovation with Shaka starts in the lab

            Because processing times are reduced so dramatically with Shaka retorts, development personnel will typically be reformulating recipes for current products and recasting formulations for new products. Shaka broadens horizons to include a host of new products that may have had some limitation in current batch retort technology. Brand owners should expect particulate products to mix better, dairy products to be scorch or burn free, and starches to have improved hydration. To assist in the research and development process, Allpax offers for sale or lease laboratory and developmental retorts that simulate the Shaka process. A lab unit will be on display at Pack Expo 2012 Allpax Booth #3910. Allpax also jointly participates in testing with its customers.

            Shaka offers solutions for these manufacturers:

  • Major brands looking for market differentiation or new products
  • Smaller niche brands with premium (organic) products
  • Co-packers that supply all market sector sized companies
  • Pharmaceutical companies looking to gain a nutritional edge for nutraceutical products or drugs requiring homogeneous mixing
  • Manufacturers that want to introduce new products in a shelf-stable format

Shaka retorts are compatible with existing batch lines relative to footprint, utilities, and operating procedures. Validating a Shaka retort line is similar to existing batch retort installations. An up to 90 percent reduction in cycle time ensures high throughput.
