Batchwise refining of chocolate, compounds, coatings, spreads and fillings based on high quality standards
The product The Duyvis/Wiener patented UNIROTO is an installation designed to combine the advantages of two very different, but well proven chocolate processing systems. The first system is the Duyvis/Wiener process, which utilizes the Duyvis/Wiener ball mill, Taste-Changer, automatic lecithin dosing and premixer. The second system is the Refiner Conche, which has been used for many years as a compact chocolate production machine. The Refiner Conche is an excellent coarse grinder and the Duyvis/Wiener ball mill an efficient fine grinder. Combining these two machines together with the Taste-Changer into one installation, the result is a complete chocolate processing plant, the Uniroto. This Uniroto concept is highly efficient and cost effective. The following types of Uniroto are: Uniroto 500 with batch capacity of 500 kg; Uniroto 1500 with batch capacity of 1500 kg; Uniroto 3000 with batch capacity of 3000 kg. The complete Uniroto system includes the following modules: one Refiner Conche; one Duyvis/Wiener ball mill, including one steel ball charge; one Taste-Changer complete with ventilator and heating element; connecting piping, jacketed for product temperature control; one electrical control panel for automatic operation. Specific advantages are: reduced processing time; better particle-size distribution; better viscosity and yield values.
The process The Refiner Conche is charged with the liquid components, such as cocoa butter (or vegetable fat) and cocoa mass followed by the solid substances, such as cocoa powder, milk powder (for the production of milk chocolate) and finally sugar (crystal or powdered sugar). Once circulating, the product pump feeds the premixed mass from the Refiner Conche via the ball mill refiner and the Taste-Changer back into the Refiner Conche. Depending upon recipe the circulation can be started either as soon as the mass is mixed or part way through the process. The Taste-Changer, also a Duyvis/Wiener patented unit, has a most important function. This unit, which mainly reduces volatile acids and humidity and adds shear forces to the mass, consists of a profiled disc which rotates at high speed in a housing. The chocolate mass is fed into the top of the housing and is subjected to shear forces caused by the pin disc arrangement. Preheated air is then blown through a separate slot and is brought into intense contact with the mass when this is spread by the disc. During the circulation process the entire mass is simultaneously ground and conched, until the required end product is obtained, which will be discharged from the Refiner Conche with the transport pump. The exact processing time is a matter of practical experience and composition of the recipe. Once known, the cycling time can be controlled and no supervision is required during the operating process.
The other advantages of the UNIROTO are: compact floor area; no skilled staff required for machine operation; minimal number of man hours required per charge; totally closed system, therefore hygienic; very low power consumption; suited to use crystal or powdered sugar; fully automated process possibility; only staff attendance required during loading and unloading; scrap can be used in the recipe; consistency of product not dependent on operator's experience.
