HAMBURG, GERMANY — F.H. Schule Mühlenbau, a member of the KAHL Group, is celebrating 125 years of supplying grain and oilseed processing plants, rice mills and related equipment.

The company offers comprehensive services from planning of the plants and operator training to repair. This includes plants for oat processing and machines for the treatment of barley, millet, sorghum, legumes and specialty crops; plants for oilseed processing; customized rice mills; plants for the production of instant food, special rice and oat flour; plants for hydrothermal treatment of parboiled rice, bulgur, cereals and legumes; and plants for pelleting related by-products.

“Due to the permanent technical advancement, 125 years of know-how and practical experience in the construction of grain mills, F.H. Schule Mühlenbau has become a competent supplier all over the world,” the company said. “Ever since Schule has become a member of the KAHL Group of companies with more than 800 employees, Schule has been able to safeguard and even increase its market share.”

Schule became a part of the KAHL Group in 1994. Schule’s machines and plants are manufactured in Reinbek, Germany, near Hamburg.

“In the modern Schule pilot plant, tests are carried out together with the customers, machines are continuously modernized and new machines and processes are studied and developed,” the company said.

The Schule story began in 1892 with Patent No. 77,786 for a table separator made by inventor Friedrich Hermann Schule. The invention made the company known in the rice milling industry, and it has continued to be the company’s best-selling machine. More than 40,000 machines have been 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 and the "gateway to the world" was opened.

As early as 1920, Schule delivered turnkey rice mills all over the world. Among them, a rice mill including a building with processing capacity of 2,000 tonnes 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.

Some of Schule’s more recent equipment includes a new shelling process for quinoa using the dry method. It also has developed a new shelling process for buckwheat that does not require any separation of grain sizes.

Due to this newly developed method, the number of machines as well as the service and maintenance demand are reduced whereas the yield of whole grains is increased considerably.

Schule has developed new drum groat cutters to meet the demand from the increased consumption of oats and other cereals.

With the TGS 2000 and the TGS 3000 models, the complete functional unit has been redesigned, which has significantly reduced the service and maintenance time. With the new knife basket, which 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 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 company also recently completed an oat plant with a capacity of 12 tph that included a 40 tph intake/silo section, a cleaning and shelling line, a stabilization section, a flaking unit and a bagging station.

To produce additional special products, an oat meal production plant and other special processes were integrated into the plant.

In 2013, Schule delivered the first main machines for a 20 tph long grain parboiled paddy rice mill in Bangladesh.

In the last two years, the customer expanded this rice mill with additional lines to a total capacity of about 50 tph or 1,200-tonne paddy processing capacity per day.
