Ocrim completes new flour mill
PAVIA, ITALY - Società di Macinazione Molini
Certosa, based in Pavia, Italy, recently began operating a flour mill built by Ocrim SpA.
Construction of the plant took 14 months after the
owner obtained the relevant permits and licenses.
The facility is producing semolina for pasta at a capacity of 400 tonnes per day.
Cremona, Italy-based Ocrim said the facility is
utilizing the newest technologies, including optical
selection (sorting) and wheat de-branning.
Before the durum wheat is sent to the milling section, it is cleaned, tempered and de-branned. The debranning degree, on which Ocrim is basing its technology, depends on various factors and can range
from 8% to 12%.
Ocrim said the main advantages of its de-branning system are:
a) yield increase with the same ash percentage, or
lower ash content with the same yield;
b) improvement of mill performance, resulting in
much cleaner stock;
c) better visual quality of semolina, as the dark
brown spots are sensitively reduced, thanks to the
elimination of black tips;
d) a 70% to 80% reduction in wheat bacterial
count, and a 40% to 45% bacterial reduction in
flours;

The milling section has a processing capacity of 400 tonnes per
The optical color sorter employs technology from SEA, an Italian
company specializing in that field that signed a commercial agree- day and has 21 roller mills, 22 purifiers and four high-performance
ment with Ocrim in 2006. The color sorter eliminates the need for plansifters.
The semolina and byproducts are sent in bulk to the storage facylinder separators and gravity tables.
Using this color sorter technology allowed Ocrim to develop cilities. A positive pressure pneumatic conveying system sends the
equipment that simplifies the cleaning process. It assures not only semolina to a nearby pasta factory.
The whole milling complex is controlled by @mill, a highly autothe removal of foreign seeds but also defective kernels such as ergot, shrunken, vetch and infested grains that are the same size as the mated system fully developed by Ocrim that has an advanced infor"good" grain but difficult to separate with the traditional system, thus mation database for the management of the plant's data. The system
controls every single machine as well as the mechanical and electricreating problems with "black points" in the flours.
Ocrim said using the color sorter increases a mill's yield and the cal apparatuses. It also interacts with the management system (acquality of the flour produced. Besides the application of the new counting, issue of invoices and receipts).
The management@mill features stock control production, lot
technologies, the new plant was designed to meet local standards for
noise levels, dust issues in the atmosphere and anti-explosion sys- retrieval, receipt management, yield control and preventive maintenance management, according to length of operation of each single

The plant consists of a grain receiving facility with a capacity of with all the economic data.
Ocrim said all automation systems are supported by the tele-as150 tph, a 20-tph pre-cleaning section and nine steel storage bins
