125 years F.H. SCHULE Mühlenbau GmbH - We have a tradition of being innovative

As early as 1910, the following entry could be found in the F.H. Schule sales catalogue: "On October 11, 1897, the Rangoon-based company Walker & White wrote to us: Several rice millers visited us who had seen your machines in operation. They were all highly satisfied and spoke favourably of them back in their companies. Since then, we have delivered more than 400 large Paddy separators to Rangoon, the largest rice processing centre in the world."

Since 1892 our company has been well acquainted with all cereal-producing countries in the world - and the corresponding cereal treatment methods. Patent No. 77,786 for the table separator made the inventor Friedrich Hermann Schule and the company of the same name known in the rice milling industry at a very early stage.

It all began on 2nd February, 1892 with the establishment of an association of F.H. Schule Mühlenbau GmbH with a steel foundry in Hamburg. At the same time, the above-mentioned patent for the table separator was filed with the patent office. Since then the Schule table separator has been the best-selling machine of our production programme world-wide with more than 40,000 machines sold. The first machines to be sold successfully on a national scale were seed cleaning machines. Later on, a second production site was established in Hamburg. Being located directly at the Hamburg waterways, direct loading onto ships was possible - the "Gateway to the world" had opened.

As early as 1920, Schule delivered turnkey rice mills all over the world. Among them, a rice mill including a building with an incredible processing capacity of 2,000 tons of paddy a day. In the 1960s, a new generation of Schule machines was introduced, including the first rubber roll sheller, the revised table separator as well as the first complete rice parboiling plant.

In 1994, the company F.H Schule Mühlenbau was taken over by the KAHL Group. The Schule machines and plants are manufactured in Reinbek near Hamburg. So they are "made in Germany". This adds to the very high quality standard. In the modern Schule pilot plant, tests are carried out together with the customers, machines are continuously modernised and new machines and processes are studied and developed.

The current Schule highlights:

A new shelling process for quinoa

In recent months, Schule has successfully commissioned a processing plant for quinoa which uses the dry method. The plant is the first of this type worldwide. It was developed, installed and commissioned successfully together with the customer in the largest cultivation area of quinoa in South America.
Quinoa - for 6,000 years already a staple food in South America - enjoys worldwide a rapidly growing popularity. It is a pseudo-cereal, as it has a similar composition to cereals. Unprocessed, quinoa is inedible because of the bitter-tasting saponins on its seed coat for protection against pests. Classical industrial plants use water for removing saponins. By repeated washing of the quinoa, the saponins are removed. SCHULE Mühlenbau has developed a dry process in which the saponins are removed without the use of water. Using the dry process, the enormous water consumption required in other processes and thus the increasing wastewater problem are avoided.

Order for a complete oats plant with a capacity of 12 t/h

Schule received a major order for the supply of a complete 12 t/h oats plant. The scope of supply comprises a 40 t/h intake / silo section, a cleaning and shelling line, a stabilization section, a flaking unit as well as a bagging station. To produce further special products at the highest level, an oat meal production plant and other special processes were integrated into the plant.
From intake to packaging – all from one source!

Delivery of a 50 t/h rice mill to Bangladesh

In 2013, Schule delivered the first main machines for a 20 t/h long grain parboiled paddy rice mill to Bangladesh. In the last two years, the customer extended this rice mill by further lines to a total capacity of now about 50 t/h or 1,200 t paddy processing capacity per day.

Development of a new shelling process for buckwheat

In the pilot plant in Reinbek, Schule has developed a new shelling process for buckwheat. Usually, Russian shelling processes are used; however, they require a large number of machines. In these processes, the non-homogeneously shaped buckwheat has to be classified into 4 to 8 grain sizes and each size has to be shelled separately. Subsequently, the husks are separated by means of screening machines and air - once again separately for each grain size. The underrunner disc sheller which is commonly used produces a relatively high percentage of broken grains, which considerably reduces the yield of accepted product. The high service and maintenance demand is another disadvantage.
The new Schule shelling process does not require any separation and it uses a new innovative shelling process. Due to this newly developed method, the number of machines as well as the service and maintenance demand are reduced to a minimum whereas the yield of whole grains is increased considerably.

New drum groat cutter, highest capacity worldwide

Since the beginning of the 19th century, Schule has built the drum groat cutter. With the consumption of oats and other cereals rapidly increasing, the demand for the drum groat cutter has increased as well. For this reason, the drum groat cutter TGS 2000 and the TGS 3000 have been developed. The complete functional unit has been redesigned, which has significantly reduced the service and maintenance time. Thanks to the new knife basket which, unlike the former models, does not have any loose shims, the time for the knife change is reduced by 75 %. This enables the operator to replace the knives within a space of only 1 to 2 hours. Another advantage is the fact that each operator will be able to replace the knives on his own after a short training period. Furthermore, the new design prolongs the service life of the knives. Due to the extremely precise position of the knives, the cutting quality is greatly improved. Thus the use of indented cylinders for post-sorting may no longer be necessary in the future. The biggest advantage, however, is the highest production capacity worldwide.
