Biomass heating at 120°C (248°F)

Water’s ability to conduct heat is unparalleled. By using standard heating technology with a flow temperature of <120 ° C (≈250 ° F), a biomass heating system is now economically feasible for microbreweries. It’s all made possible by Kaspar Schulz‘s reliable wort technology—the Gentle-Boil System SchoKo 2.0 and the SchoKolino 2.0. Hot water with a temperature of <120°C (≈250 ° F) serves as a medium for heat transfer to warm the brewing vessel. Above all, the advantage lies in the fact that by employing said standardized boilers, the use of biomass furnaces in microbreweries becomes economically viable. In the long-term, you will observe an increase in energy efficiency and, eventually, the use of fossil fuels will be replaced by biomass material. In addition to adequate brewhouse technology is the need for an intelligent automation solution. Communicating the processes to be controlled is important in order to compensate for the inertia of a biomass boiler. A consistently high heating rate of the mash and wort make for a more reliable process sequence and consistently high wort quality.

When selecting a boiler manufacturer, Kaspar Schulz puts their trust in the experience of HEIZOMAT—over 20,000 boilers under their belt and an all in-house manufacturing philosophy to boot. 100% Made in Germany.

NO|CO[2] - Climate-friendy and autonomous 

Due to fossil fuel consumption, any given German brewery emits an average of 12.9 kg (28.4 lb) of CO2 per hl of beer. With the present electricity mix, radioactive waste accrues to 0.008 g (0.0003 oz.) per hectoliter of beer.

At the heart of the concept for a CO2-neutral brewery is the recovery of biogas from the 'waste' materials left over from the brewing process. Spent grain, yeast, sediment and waste water contain so much energy that they could provide nearly 82% of a brewery's total heating requirements. Harnessing this energy requires of course the use of the Gentle-Boil System SchoKo, since wort boiling is known to be the most energy-intensive process in the production of beer.

Through the use of of biogas in a dual function heat and power plant, 45% of the heat and 72% of electricity requirements can be recovered from 'waste' materials. In particular, the high coverage ratio for electricity makes it possible to obtain the missing quantity of electricity and heat from renewable energy sources. The area required for a photovoltaic system is reduced threefold. The necessary remaining heat can be easily acquired by use of the biomass.

The CO2-neutral brewery from KASPAR SCHULZ

We're taking it one step further with a CO2-depleting brewery. Through the acquisition of fermentation substrate and the gained quantities of gas, a power surplus can be generated, which in turn is fed back into the public network. The CO2 balance for operation is thereby negative. Even the CO2 emissions caused by transporting the finished beer could be reimbursed. The ecological footprint of the carbon-neutral manufactured products need not fear a labeling requirement in the future.
