The pin worker unit is mainly used for intensive treatment of margarine and edible fat products, in order to achieve a proper crystallisation and right texture during the production process. Depending on product and desired consistency the pin worker unit can either be placed between the cooling steps or at the end of the cooling process.
The RONO pin worker unit is based on proven technique. Our further development enhanced the pin worker to meet best flexibility, highest standard of hygiene, very long life expectancy and easy maintenance in daily operation. The RONO pin worker unit offers highest flexibility to the production process and allows to work with a wide diversity of fat products. Adjustments to the level and intensity of treatment can be made by adjustment of the pin rotor speed.
Production capacity and volume of the pin worker unit offers a variable duration of kneading. Product crystallisation can be influenced by the choice of high or lower pressure production.
