Liwayway (Oishi), Asian multinational and market leader in over 10 states when it comes to reconstituted products and snack foods, has chosen OMAS technology to build the first alternate mill in the world, to process multi-grains and legumes.
In July 2017 the company LIWAYWAY and OMAS tried out the world’s first alternate mill, able to produce 20 types of semolina or 15 types of fine flour, alternating between the two.
The new plant, installed in Ho Chi Minh City, has been built to produce raw materials for the three processing sites in the south, centre and north of Vietnam.
It has been installed in a combined cement-steel structure inside an existing hangar, reconditioned and raised to the vigorous hygiene standards required for food production.
The plant will alternately produce the semolina and flours that are the ingredients for extrusion, expansion, baking, drying and frying over 30 snack food lines.
LIWAYWAY in fact has a 70% share of the Vietnamese market with over 45 different types of snack, known by the trademark “Oishi”, founded in 1974 and a great success throughout the Far East.
The innovatively designed mill will manufacture all products in an entirely automated manner, using repeatable recipes, stored to memory.
Omas, competing against the most important milling system manufacturers has been awarded the contract to supply the plant thanks to the following advantages:
One-of-a-kind technological flexibility, thanks to the cutting-edge LEONARDO roller mills that allow independent roller speed variation and milling configuration.
This technology, created for the first time, allows the passage from the “Cut-Cut” configuration for maximum extraction of coarse semolina to a “Back-Back” configuration for maximum fine flour milling.
This solution prevents the need for a dedicated complementary section that is in stand by to re-mill coarse semolina into flour.
The roller mill, which has 300 mm diameter rollers with variable rpm, can achieve any milling ratio from 1:1.25 up to 1:5 and can mill maize, rice and legumes with a better ratio.
The Galileo plansifter with variable rpm, lightened aluminium framework and sandwich insulation panels in stainless steel with 25 mm polyurethane core prevents the dew point and cultivation of bacteria. Frames and supporting frames in aluminium alloy also stop the wear and tear that occurs when processing highly abrasive materials such as rice and maize.
In just one step, the Verdi horizontal degerminator is able to separate 65% of low-fat content grits from the germ, bran, and flour, for animal feed use.
Energy use is reduced by 50% for the roller mills, thanks to the installation of the KERS device.
The complete absence of transmission belts on the roller mills, which means no maintenance, breakages, dust or dirt.
The automation project together with changes in production between semolina and flour with dedicated recipes complete with different speed settings between rollers without having to change their positions.
The software for the main milling equipment is made to communicate working data to a remote maintenance management station compliant with European standards for plant efficiency: “INDUSTRY 4.0”.
A plant that is one of a kind, a great success for LIWAYWAY and OMAS, a co-project with a vision that looks to the future for continued research into new processes and a relationship of trust going back 10 years now.
