Mash Filter Pneumatic Preheating

The patent applies pneumatic heating by using heated air instead of heated water to preheat the mash filter. The heating device introduces heated air into the mash filter, which circulates through the filter structure and heats the plates and internal components. This pneumatic approach eliminates the need to fill and empty large volumes of water, thereby preventing water waste while still achieving the required temperature of 50-60°C.

The patent introduces heated air as an intermediary heating medium between the heat source and the mash filter. The heating device acts as an intermediary system that generates heated air and directs it into the mash filter, allowing heat transfer without requiring direct contact with large amounts of water. This intermediary approach enables efficient heating while avoiding the water consumption and waste associated with traditional water-based preheating methods.

The patent uses pneumatic heating with heated air instead of hydraulic heating with water. The heating device generates heated air that circulates through the mash filter, transferring thermal energy efficiently. This pneumatic system reduces energy consumption compared to heating and circulating large volumes of water, as air has lower heat capacity and requires less energy to heat and move through the system.

The heating device operates continuously or in repeated cycles, introducing heated air into the mash filter until the desired temperature is reached. This continuous heating action ensures efficient heat transfer and minimizes energy waste by maintaining the heating process only as long as necessary to achieve the target temperature of 50-60°C, avoiding the energy-intensive repeated filling and emptying of water.

The patent uses heated air to uniformly heat the mash filter plates and internal structure before hot mash is introduced. The pneumatic heating system distributes heated air throughout the filter, ensuring even temperature distribution and gradual thermal expansion of materials. This prevents thermal shock and stress that would occur if hot mash were introduced into a cold filter, thereby protecting the filter materials while still allowing for relatively quick preheating.

The heating device performs preliminary heating of the mash filter before the hot mash is introduced. By preheating the filter to 50-60°C using heated air, the system prepares the filter materials to withstand the subsequent introduction of hotter mash without suffering thermal damage. This preliminary action protects the filter's reliability and extends its operational life.

The patent uses pneumatic heating with circulated heated air to achieve rapid and uniform temperature distribution throughout the mash filter. The heated air can penetrate and circulate through the filter structure more efficiently than water, achieving uniform heating in shorter time periods. This pneumatic approach reduces the contact time needed compared to traditional water-based methods while still ensuring temperature uniformity across all filter plates.

The heating device operates continuously, introducing heated air into the mash filter without interruption until the desired temperature uniformity is achieved. This continuous heating process is more efficient than intermittent water filling and emptying cycles, as it maintains constant heat input and promotes uniform temperature distribution more rapidly, reducing the overall heating time while ensuring thorough heating of all filter components.
