Bakery qualities of grain — Cambridge, Great Britain

In Cambridge in August 2012 Plot Feeds Ltd company on the basis of national agricultural centre Niab-Tag, Great Britain, conducted a number of experiments on CAD separators. In particular, researches concerned the impact of calibration of wheat with the CAD separator on the change of the Hagbert number (falling number).

Hagbert number - indicator of flour quality, the optimal value of which is - 250. Hagbert number in flour that is less than 200 leads to the fact that dough becomes sticky, bread-crumbs rough, dark with a sticky texture, and noodles or paste from such flour is fragile and soft.

The research was carried out on three varieties of wheat: Hereward, Solstice and Cardiale.

In first experiment substandard material with the low Hagbert number after the first calibration on CAD machine was improved in 2,3 times, and when re-calibtaed in 2,9 times (see table 1).

Table 1
Variety Initial hlw weight Initial hagberg % grain taken hlw after cleaning hagberg after cleaning
Hereward 70,3 98 64% 77,8 222
Hereward 74,7 104 80% 80,1 227
Hereward повт. Тест 74,7 104 50% 81,2 342
Solstice 68 211 50% 78,3 382
Solstice 69,3 216 72% 76,8 342

In second experiment the task was: as much as possible increase the Hagbert number with the help of grain separation on CAD machine. Results showed that in 2,6 times after first separation and 3,5 times during second (see table 2).

Table 2
Variety Initial hlw weight Initial hagberg % grain taken hlw after cleaning hagberg after cleaning
Hereward 74,9 116 72% 80,6 296
Hereward повт. Тест 74,9 116 30% 82 401
Hereward 75,8 154 72% 80,7 359
Cardiale 75,9 260 64% 79,8 387
Solstice 70,8 193 76% 76,9 368
Solstice 78 280 86% 80,3 348
Cordiale 76,3 233 70% 79,9 350
Solstice 64,4 204 68% 77,9 304

In third experiment the task was to obtain the optimal Hagberg number - 250. After the re-separation of it was achieved (see table 3).

Table 3
Variety Initial hlw weight Initial hagberg % grain taken hlw after cleaning hagberg after cleaning
Solstice 74,8 243 80% 78,4 319
Solstice повт. Тест 74,8 243 92% 76,8 250

Conclusions: Separation on CAD machine - is simple and highly-effective means of improving the baking qualities of grain!

Recommendations: CAD separators are recommended to be used in technological lines of the flour production, especially with low quality of initial grain.

We remind, leaders of the flour-grinding industry of Ukraine, such as: Myronivsky Hliboproduct, Luganskmlyn, Khmelnitsky Mlyn, Milam and others are our business partners and use in their work CAD separators.

We invite enterprises of the flour-grinding industry to cooperation!

During the harvesting and preparation of grain crops for storage, it is very important to accurately complete all stages of the post-harvest process. One of the most significant steps is grain cleaning. It makes it possible to save the crop from dust and impurities, weeds, pests, dry mass, separate the seeds, and also qualitatively prepare the grain for further storage and processing. Universal grain cleaning equipment CAD separators has a high capacity, processing almost all types and varieties of crops, legumes, oilseeds, industrial, small-seed herbs and vegetables. The grain separator can be used independently or in combination with other units, performing the complete chain of processing crops. AEROMEH company offers grain cleaning machines for various tasks. From us you can buy small separators CAD-4 and CAD-5 for small farms, as well as grain separators CAD-100 and CAD-150 - more productive and always efficient. Grain cleaning equipment of AEROMEH production consists of several components. Grain enters the hopper feeder of the CAD separator. With the help of the vibrating tray, the grain is evenly distributed in the separation chamber over its entire width. Air flow generator of the CAD grain separator processes each element of the separated stream with the powerful flows. During this process, the heap is cleaned of dust, light impurities, crushed grain, weed seeds and other mineral and green impurities. Separation or sorting of grain with the CAD separator is done into 5 fractions. After cleaning with the separator CAD, the best and cleanest grain goes to the 2nd and 3rd fractions. Small impurities, crushed seeds and waste of various origins go to the 4th and 5th fractions. In the calibration mode, the 2nd and 3rd fractions of CAD separators is proper seed material, which is obtained by selecting the grain by the specific weight. The equipment has durable body, and does not have replaceable elements and lubrication points, therefore it can work for many years without failures in operation. At the peak of the season, when the grain cleaning is carried out for many hours in a row, it is very important that the machines work clearly and smoothly, because every day of a downtime can bring losses to the agricultural economy. We offer reliable equipment that does not require expensive consumables or special care, it gives maximum efficiency without taking significant investments. AeroDynamic separator CAD is a modern and reliable grain cleaning equipment. Innovative solutions used in the CAD separator allow to solve a lot of problems in the field of grain cleaning. In addition, CAD is a technology for producing high-yielding seeds. Time tested. phones.
