This process occurs each time a raw materials load enters our facilities. Reception is performed as follows:
1.- Transport registration and reception within our facilities.
2.- Load uncovering and subsequent review and checking of transport conditions (qualitycontrol).
3.-Sampling and entering analysis of raw materials (quality control).
4.- Unloading at reception yard.
It takes place in the reception area when unloading the raw material, for which there are two cleaning sieves. The process is performed in order to remove the greatest possible amount of foreign bodies bigger than 7 x 11 mm and those of less than 1.5mm diameter, together with the removal of a high percentage of fine dust, dirt and other particles. After pre cleaning, the raw material is stocked in one of our seven available silos.
The first stage of the process within our plant. Equipment in this line removes all the seeds and foreign materials.
This process begins when cleaned oats enter an air peeler where husks are removed through a system that throws the grains against a cylindrical steel surface that is coated with high-density polyurethane for the husks to open and release the kernels. Husks, kernels and fragments are thus obtained and subjected to a cleaning process by means of an air stream. Then they are transported to a scouring machine to help loosen the kernels that are still stuck within the husk. They are finally transported to a 'paddy table' where grains with husk are separated from totally clean kernels, which will follow to the next stage.
At this point, grains enter a vaporizer in which they are hydrothermally treated (steamed) at 104 °C for enzymatic deactivation. Afterwards, they are dried and roasted in three conduction heat transfer chambers, and then transported to a cooling chamber where they reach room temperature. After this process, grains might have two destinations: they either follow through to the cutting line until obtaining rolled oats, or being transported to the packaging silo for marketing as finished productsin 25kg.
The process is performed in four two-drum cutting machines. Grains are cut with stainless steel knives and the resulting product is sifted in order to remove airborne dust and light materials. It is then sent to a 'Planfsister' in which grains are classified according to two different measures; both types of grain go through a second cleaning and are eventually classified in a "trieur". This way, grains become clean and ready for flaking.
After hydrothermal conditioning, grains are passed to a cylinder laminator, where oats flakes are obtained. This product is then sent to a fluid-bed dryer and cooler in order to remove excess moisture and cool it to a temperature that allows adequate packaging and storage. The dried and cooled flakes are selected and cleaned in a separating machine and then sent to the packaging silos. The process ends at an automated bagging system, which packages the product in waterproof laminated polypropylene bags.
This line begins with the pneumatic transportation of rolled oats that might come directly from the rolling line or from temporary storage. For flour elaboration, a receiving silo is used for accumulation of flakes, which are subsequently taken to a hammer mill where, by means of different types of fabric, products of different grain sizes are obtained. Afterwards, products are sent to internal storage within the plant to be transported to the packaging silos, where they are bagged in laminated polypropylene bags in different weight presentations.
