Spiral heat exchanger 60m2, 12/12 mm AISI 304

Spiral heat exchangers for distilleries. At the distillery, a bioethanol plant where alcohol is produced from starch-containing raw materials, the following technological cycle is used: - mixing with hot water that comes out of the spiral heat exchanger heated to a temperature of 80-90 degrees . The water is heated on a spiral heat exchanger, in technology it is called a recuperative spiral heat exchanger of the cooking compartment . - spiral heat exchanger for cooling the wort after GDFO (hydro-enzymatic treatment) cooling the wort with the inclusion of 20-25% of dry substances from a temperature of 90 ° C to a temperature of 60 ° C (in the case of using a saccharifier) or to a temperature of 32-35 ° C (in schemes that do not use a saccharifier in the technology). Spiral heat exchangers have proven themselves very well instead of built-in coils in fermentation tanks (built-in coils-heat exchangers inside the fermentation tank) are poorly washed due to the design features of the placement and therefore leads to microbiological contamination of the Braga. The removed spiral heat exchanger for wash cooling is well washed. When washing the fermentation tank, water is also pumped through a spiral heat exchanger. Spiral heat exchangers have also proven themselves in recycling water supply systems using natural sources that act as a refrigerant. Spiral heat exchangers or spiral heat exchanger stands on the primary circuit-pond, river, storage. Heat exchangers with a removable cover are easily cleaned from dirt and can be used for heat carriers with solid inclusions or biological deposits, thereby clogging the flow, as in plate heat exchangers. Structural features of manufacturing spiral heat exchangers. In order to strengthen the design of the spiral heat exchanger, spacers are used between the sheets of the spiral heat exchanger-pins. The pins between the sheets of the spiral heat exchanger are made of a material similar to that of the sheet of spiral heat exchangers. Fix the pins by welding to the sheet of the spiral heat exchanger. Spacers between the sheets of the spiral heat exchanger-pins
