GOLFETTO SANGATI
Milling technology, not just for grains. An in-depth study of logistics and functional solutions of its plants represents the know-how thanks to which Golfetto Sangati develops specific proposals for their customers, working side by side with them as a technological partner. The firm aims at establishing relationships based on trust, ensuring specialised and qualified consultancy, developing an operation plan that undergoes feasibility studies, and in-depth technical analyses, in order to identify the best solutions and the most efficient technologies. One of Golfetto Sangati’s distinguishing strong points is the ability to develop technologies for milling products other than grains, particular raw materials the processing of which requires specific know-how. CAROB FLOUR In 2013 a series of Synthesis rollermills were developed, which were designed for processing Carob (Ceratonia siliqua) seeds, a plant belonging to the legume family, typical of Mediterranean countries. Carob flour is a natural additive, it represents a hydrocolloid derived from hulling and milling of its seeds, and it is classified in the European list of food additives with mark E410. This hydrocolloid product, 24
called ‘carob’, is a galactomannan. Its structure consists of a chain of mannose with ramifications of galactose, in the ratio of 1:4. It is widely used in the food industry as a thickening, emulsifying, stabilising and jellifying agent for canned products. Thanks to its content of glactomannans, carob is widely used also in cosmetics and pharmaceutical industry as a thickening and emulsifying agent for creams. The whole milling system for carob flour (dropping piping, hoppers, pneumatic manifold, filter, settling cyclones, star valves with rotor and case) is manufactured in stainless steel for food processing, the same applies to all parts of the machines that come into contact with the product, in order to satisfy the most demanding health and safety requirements. The newly designed rollermill is equipped with a bell shaped hopper conceived to enhance product entry inside the machine. Capacitive probes check product level in 8 different reading points, and electronic devices on board of the machine are able to make the speed of the supply rollers suitable with respect to the product level detected and set in the bell shaped hopper.
GRINDING OF SALT Amongst the most innovative projects, the design and accomplishment of a series of Synthesis rollermills developed for salt grinding stands out. These are installed inside a mine, at a depth of 140 metres. These machines, which are manufactured entirely in stainless steel, are able to process various grain sizes of product, between 1 to 5 mm, and they are equipped with a bell shaped hopper specifically developed to enhance entrance of rock salt. The laminating rollers are manufactured with a special material, to ensure the utmost precision and efficiency in grinding, which requires specific technical methods. Competence of personnel, as well as flexibility in the research for more efficient solutions, combined with sturdiness and manufacturing quality of the machines, represent the fundamental elements for choosing Golfetto Sangati as a partner who is able to ensure continuity and efficiency in any production context.
