Directed fermentation technology

Beside our standard equipments (which can be found first of all in mini- and small vineries) we locate technologies after custom-made designs for medium- and large vineries too. Their capacity and engineering parameters are determined by the feature of the vinery, that is why we can not pan out about this.

Main equipments of our technology are absolutely factor-specific due to unique needs but of course they were built by similar principle. These are the following:

Speciality of our operative technology in a few words

Our technology is capable to heat or cool all kinds of fluid rations (vine, must) among given limits. Even by high-temperature cicumstances it provides facilities to keep the defined heat- and cool- parameters. In vineries it is able to heat and cool must or vine, and keep its temperature automatically in level among defined limits, and this way effecting directed fermentation. In addition it is excellente for decomposing malic acid and cold treatment.

Its guidance is automatic, does not require any supervision. The temperature of product, the coolant and the heat-agent are observed by a digital displayer and programmed heat-adjusters. They transmit the information and data to the computer that controls the system by the right of them. Heating and cooling of the products have indirect method that is matelialized by a permenantly regulated temperature heat-transfer medium. By means of modern-microprocess process control the technology can be tuned up with severly lange accuracy among wide limits, act upon the microbiological attributes of the handling product.

Short-technology process

In virtue of the technical solution, more than fifty directed fermentation systems are in operation, equally abroad and home.

According to operative technology the buildup of liquid cooler and the cooling cycle of tanks archieve with unattached rounds (primer and seconder) in the way, that the liquid cooler cools the coolant directly in the so called ˝puffer˝ tank. It is cooled until it reaches the correct temperature. The fluid of this tank is circulated by a wheeling pump, in right regulated procession in the tanks cooler-cloak (secunder) through cooling cycles because of the buildup of the ideal stream and heat-transfer conditions.

In case of heatable tanks, technology is similar. The difference is, we produce warm water concurrent cooling and heating with the liquid coolers discart heat. Without syncronism we manufacture it with gas-boiler or electric boiler, which is going to be detached from the system by a heat exchanger.

We use the similar solution with heatable and coolable tanks and if necessary with tubular heat exchanger too.

Advantages:

• Energy-safe factory;
• Less on/off swiching;
• Resilient technology can be realized by keeping the optimal (variable) level of coolant temperature (ideal microbiological effects are achievable);
• Due to restored heat in puffer tank, the system is more unaffected to sudden heat-load;
• There is no deaeration problem, the status of coolant can be checked easily.

The calculated electric control of the system aims for maximum factory-safety from operation aspect, that is why we developed a contructed error-indicating system. This guarantees signs in time if the equipment failures. So it encumbers the formation of an irreversible microbiologycal process. It has reference to full protection and cooling cycle.

We design and stylish the system by industrial computer hydraulical adjustment. This means that even in worst factorical circumstances standard mass flow coolant circulates in every single consumer of the system.

The electrical guidence of the system happens during installation in the way, that beside full-loading we observe (by the industrial computer) the conditions of the cooling cycle of tanks. In line with this, the computer observes tanks and also the changes of glycol-temperature and then records the results. The parameters of the tank depends on these data. On the grounds of this during fermentation period we can reach the optimal product temperature by the help of computer. This way we adapt to peculiarity of the product.

Till now this dual-regulating solution is being used in Hungary only by us. The consequence of this product-orientated technology is that the product gets only the most needful heat load.

The effects are the following:

• No overheat, overcool, heatshock;
• Larger safety of factory and technology;
• Nature-like heat load;
• Better product quality;
• Easier supervision and handling;
• More consistant coolant temperature at every point of the system;
• Favourable power expenditure (energy saving).

We designed cooling technology that it is capable to preparate –10 °C glycol. In tanks –3 –4 °C product temperature can be generated, so cold treatment achieves.
