Popis projektu: Projekt je realizován v rámci Operačního programu Podnikání a inovace pro konkurenceschopnost. Předmětem předkládaného projektu je zvýšení konkurenceschopnosti společnosti J4 s.r.o. na zahraničních trzích, a to pomocí podpory účasti firmy na 7 mezinárodních veletrzích v letech 2017 až 2019. Účast na vybraných veletrzích přispěje společnosti k novým zakázkám, zvýšení obratů a také k celkovému růstu společnosti. Projekt je spolufinancován Evropskou unií.

The company J4 s.r.o. deals with the development, production, repair, service and supply of cyclothermic, electric, convection, direct heat and hybrid tunnel baking band ovens and the supply of complete baking lines for bakeries. In 2007, J4 took over all technical documentation, including trademarks, and thus became the sole legal successor of the company Továrny mlýnských strojů Pardubice (TMS – milling machinery works), which used to produce and supply ovens all over the world from 1973 – 1998.

The company production assortment includes technologies suitable for semi as well as fully automated high capacity production factories and middle size bakeries or pastries. The entire baking process is controlled by a computer according to the wishes of the client, together with special software enabling to manage up to 300 various recipes, so that the complete process is unmanned.

Production of band ovens

We produce baking band ovens in single-deck and double-deck design, in widths ranging from 0.6 to 4 m, in lengths and design according to our client’s needs, with wire mesh, plate (louver), granite plate and steel conveyor bands. As a source of energy for baking, these types of heating mediums can be used – gas, diesel, oil, black oil and last but not least electrical power. Ovens not only serve for baking rye, rye-wheat and wheat bread but also for various types of pastry and fine short pastry (such as rolls, buns, Kaisers, hamburger and hotdog buns), Arab bread, pita bread, sponge cake dough (e.g. children’s sponge cake biscuits), gingerbread, cookies, solet salted sticks and other sticks, pretzels. Overview can be found here.

The principle of the equipment, designed and developed by our company, stems from the original licence of the German company Winkler. During over twenty-five years of development and supply, more than 1500 pieces of equipment have been installed throughout Europe and Asia, all functioning reliably upon this principle, primarily in food businesses.

The company’s headquarters are situated in its very own production site in Předměřice nad Labem. Here we produce not only new PPP type baking ovens, but also the spare parts for repairing ovens.

According to client demands, we also supply the turnkey complete production lines in addition to individual ovens.
