The safe, energy-efficient, and scalable process for producing high quality shelf stable bulk fruit and vegetable purees.

Raleigh, NC: SinnovaTek, a leading developer and integrator of advanced food processing equipment and technology, announces the SinnovaTek Continuous Flow Bulk Microwave Sterilization Systems for processing high quality shelf stable bulk fruit and vegetable purees. The safe, energy-efficient, and scalable process rapidly and gently produces high quality products with excellent retention of colors, flavors, aromas, textures, and nutrients.

The SinnovaTek sterilization skid can plug into new or existing production lines to improve the flavor, texture and color of existing products and to convert frozen puree products to shelf stable product lines. Shelf stable products sterilized with the system have tested as equivalent to pasteurized, refrigerated products in terms of freshness perception, likability, and purchase intent.

Microwave processing is extremely efficient. It is a direct, volumetric form of thermal processing that is 2.5x more energy-efficient than steam processing, an indirect form of thermal processing characterized by energy loss through thermal transfer. Microwave sterilization may be powered by a range of sources including renewable energy. The SinnovaTek continuous flow process uses only 1/10 of the pipe length of a conventional heating system, resulting in a smaller footprint and a reduction of product waste.

Three models are available. The portable Nomatic system, designed to accommodate throughputs from 0.5 – 3 liters per minute, is ideal for commercial applications where limited quantities are needed and small frequent runs are optimal. The Nomatic systems operate at 2450MHz and can range from 6kW to 18kW of applied microwave power.

The Pilot and Commercial Scale systems are for larger scale processing and operate at 915MHz.  These systems are designed to accommodate throughputs from 2 – 30 gallons per minute (gpm). They can range from 75kW to over 1,000kW.

SinnovaTek microwave sterilization systems are highly versatile, meaning they can be used to process thin, liquid-type products such as juices or milk all the way up to thick and viscous products such as mashed potatoes or hummus. The larger systems can also run products that can contain particles, including salsas, soups, and fruit purees with chunks.
