Mahesh Patil, RIECO

RIECO is an established name and has been a pioneer in engineering and manufacturing of Size Reduction Equipments (SREs) for a variety of applications, over the past 30 years. For fine grinding of a wide range of materials such as Spices, Food products, Sugar, Pesticides, Chemicals, Dyes & Pigments, Bulk Drug, Power paint and Food items (Sugar, spices, Wheat and many other materials), RIECO offers

  • Mikro-Pulveriser
  • Air Classifying Mills
  • Universal Mills and
  • Micron Separator for separation of super fine powders.

RIECO has a proven database and can design, engineer, manufacture and commission specialized Plants for Spices Grinding such as Red Chilly, Coriander, Turmeric as well as Mixed spices.

To ensure the production capacity and deliverable micron size (fineness) of the system a comprehensive and in-depth study of the various spices and their behavior at different temperatures has been undertaken at our laboratory that is certified by the DST. Various trials and experiments have been conducted and the results compiled and analyzed. All this scientific data has then been put to use while designing the equipment depending on the application and the Client's requirement. Many a times, our existing clients have partnered with us in this developmental activity and have reaped the benefits of new advancements. For instance, we have now developed a sophisticated system that can grind spices in controlled atmosphere. This new development is finding many takers already.

Process description

A typical project will envisage setting up of a Spices grinding unit (for Cumin, Turmeric, Chilly etc). This is a new concept in Spice processing, which results into higher production with better quality of the end product not just in terms of aroma but also the much desired color, than any conventional Spice grinding unit. RIECO technology uses chilled air at 15-17 degrees to control the grinding chamber, the result of which is reduction in loss of volatile or essential oils in the spices and higher production rate.

This type of grinding improves the aroma by minimizing the loss of essential oils (approximate 3-10% loss) which can be as high as approximate 15-43% in conventional processing. This type of technology is particularly important for Cumin processing. Spices are ground to a uniform fineness of 500 microns, as compared to a size range of anywhere between 600 to 1000 microns using conventional grinding processes.

Advantages with RIECO technology

The technology has been developed with many hours of analysis and engineering, as well as taking into consideration aspects to produce the best possible produce from the equipment. At the same time due consideration has been given to minimizing industrial hazards while designing the equipment.

RIECO offers the following distinct advantages.

  • Spices processed using cool-grinding retain natural colour to a far greater exent,
    as compared to those ground with conventional process. This is especially critical
    with products like Chilly and Turmeric powder.
  • Finer particle size with uniformity can be achieved.
  • Losses of natural aroma are greatly reduced.
  • Overall grinding capacity can be increased by 1.5 times, as process equipments
    will not have thermal fatigue due to heating up.
  • Fire risks too are eliminated as temperature during processing is controlled.

  • This method of grinding enhances unlocking of the natural flavors, aiding
    easy dispersion of the same and controlling the flavor strength.
