Successful in the Saudi Arabian market: Best Brand Ready Mixes for both bakeries and the retail market.
In 1991 the Refco company arranged contracts with three partners to implement the project:
Macphie Export Ltd of Scotland as marketing advisor and licensor for the products to be made;
Buhler Ltd of Switzerland for the overall engineering and supply of the mechanical and electrical/electronic equipment.
And Al Mofti Engineering Consultants for designing and constructing the production building and infrastructure.
The 24m high blending tower houses not only the ingredient bins for various flours, sugar and starch but also the storage tank and metering and weighing system for liquid fats. The building is air conditioned, so the storage and processing temperatures do not exceed 25 [degrees] C, to maintain product quality. Following careful design and construction, and successful start-up, the plant was handed over to managing director M Najib Kheder in 1993.
Proportioning, Weighing, Mixing
The stainless steel DFMF-10 batch mixer is mounted directly on an electronic 500kg scale. First, the major ingredients are proportioned and weighed. Then the minor ingredient scale is discharged and the manually loaded ingredients added. Liquid fat is injected between the dry and the wet mixing operations. Before the batch - weighing 500kg and blended according to product formula is conveyed to the packaging section, it undergoes homogenization in an MOZJ unit. The proportioning and weighing system for minor ingredients, Type MWBU, includes six storage hoppers of stainless and mild steel for salt, emulsifiers and baking powders. The MZML microdosing units feed the ingredients into the pivoting batch scale, which is also of stainless design. Complete discharge into the mixer ensures both the accuracy of the product formula and a high degree of hygiene. Colouring and flavouring agents, and the baking aids, stored in twelve micro-ingredient containers, are manually proportioned and tipped into the mixer. The stainless steel movable hand dump container incorporates an MKSA-75 oscillating sieve that can be docked with any container. And connection to the exhaust system ensures dustfree loading of the micro-ingredients.
Low protein cake flours are being increasingly used in private households. However, the flour made from Saudi Arabian wheat is strong and therefore unsuitable for a number of baked goods. For this purpose, a classifier mill has been installed in the fine grinding and air classification section for milling normal bread flour to such a fineness that it can be fractionated, in the subsequent air classifier, into low protein coarse and high protein ultrafine fractions.
Automatic or Manual
The control system consists of standard modules developed by Buhler. The plant can be operated through the mimic diagram in the automatic or manual mode. For job processing, a colour visual display unit is available, offering the following functions: Material definition, Product formula management. Job processing with queues, Construction and formula statistics, and a Weighing log.
Quality Inspection and Assurance
In the in-plant experimental bakery, the ready mixes are tested, processed, presented and tasted. Product formula technology is under the responsibility of Macphie Export Ltd, a company that has established a reputation for speciality products by innovation and development work.
