Dvorak - engineering is an engineering company, in which on the basis of your task a team of professionals works on the optimal solution of the task. When searching for such a solution we first of all pay attention to several important factors. We pay great attention to energy saving - in some cases it is possible to achieve absolute energy independence of the project.

Dvorak - engineering is an engineering company, in which on the basis of your task a team of professionals works on the optimal solution of the task. When searching for such a solution we first of all pay attention to several important factors. We pay great attention to energy saving - in some cases it is possible to achieve absolute energy independence of the project.
No less important for us is the cost and profitability of the project - we take into account the amount of investment required, as well as the price of the raw material to be processed, the capacity of the line and the expected value of the finished product, which ultimately determines your profit. As an engineering company, we focus on finding new possibilities and technical solutions in production and line design. This is supported by the reputation and long tradition of the Czech Republic in mechanical engineering. Together with the experience accumulated over the years, this gives us the necessary freedom to find cheaper and energy-efficient technical options.
When implementing the project, we can achieve significant savings when selecting and completing the individual units of the process line. This is the main advantage of engineering - first and foremost, the planning, know-how and many years of experience of our engineers. As a result, you get a cost-effective process line instead of an idle pile of iron. We take full responsibility for our projects on all counts, including installation, commissioning, start-up, warranty and post-warranty service and spare parts. We also provide advice through our 24-hour technical support line.

Our Moscow office co-operates with experts from different regions, as well as with the Ministry of Agriculture and its representative offices in different regions in conducting research, which, if necessary, is part of the project. During the implementation of the project we also conduct market research, i.e. local supply and demand ratios, purchasing power, price and quality of competitive products and other important information. After that we prepare a document that provides maximum information for our clients to make a final decision on the project implementation.
In this area of the market, we co-operate with leading specialists in the industry. Whether it is for the supply of equipment for wind farms, chicken manure processing in poultry farms or for municipal waste management, we are always ready to fulfil our customer's requirements with the supply and subsequent completion of equipment manufactured mainly in the Czech Republic.
This is an important point for clients who wish to finance the project through the Czech Export Bank
with very favourable lending rates. The quality of all our projects, technical solutions and supplied equipment is confirmed by many years of experience gained in the realisation of projects of various degrees of complexity, as well as by the available certification.

Waste recycling
batch technology
The consumption of meat products in the Russian Federation, as well as in Europe, has been steadily increasing recently. The number of organisations involved in the breeding, fattening and slaughtering of poultry and poultry is also increasing.
The majority of poultry farms and meat processing plants have their own slaughterhouses, an integral part of which is the process of processing slaughter waste of a small volume of input raw materials. The quality of meat and bone meal and the ability to use it effectively in animal and poultry feeding depends on the technology used and the equipment installed in this area.

The quality of meat and bone meal and the ability to use it effectively in animal and poultry feeding depends on the technology used and the equipment installed in this area.
In the offer of Dvorak engineering company there are waste processing lines with batch technology, which are most often used for liquidation of confiscates of slaughtering and meat processing lines with the volume of input raw materials up to 3 tonnes per hour.

under these conditions for half an hour. After this time, the pressure is reduced and the temperature drops accordingly, resulting in the evaporation of about 5 per cent of the water. During the drying process, which follows the sterilisation of the raw material, a further 60% of the water evaporates. The final moisture content of the boneless meat porridge is 4 - 6 %. The resulting juice vapours flow through a valve into the condenser.

Designing responsibly
Engineering and integrated solutions for the utilisation of biological waste such as manure allow us to
not only find an efficient method of disposal, but also optimise production, which in the end
tangible benefits.
Many of our customers come to us already having the necessary equipment for manure processing, but not being able to achieve their goals. For example, we were recently approached by Mr Mihan Nanu, CEO of the Romanian agricultural holding company Recoltare. This company had built a biogas plant two years earlier to convert chicken manure into biogas.
However, according to the Italian design company that supplied the technology, the profit margins were never realised.

Our experts, having analysed the problem, came to the conclusion that the litter from this poultry farm is not suitable for the biogas plant.

Due to the high chemical activity of chicken manure, the processing technology involves mixing the material with a much larger volume of maize silage and dry grass. In the end, they were only able to

Our engineers modernised the plant and now Recoltare buys pig manure from a nearby farm and produces energy for sale. They burn the manure from their poultry farm in specially designed boilers designed and supplied by our company Dvorak-engineering. From 100 tonnes of manure per day they get 2.5 mWh of electricity, which more than covers the needs of the whole holding.
Many of our customers come back to us repeatedly because they are convinced that we focus on efficiency and customer needs, while other companies try to convince them that only their products can be efficient.
