Falling film type wheat juice boiling system and boiling process thereof

Abstract

The invention relates to a falling film type wheat juice boiling system. The falling film type wheat juice boiling system comprises a boiler, a falling film evaporator, a variable frequency pump and asteam jetting pump, wherein the boiler comprises a boiler body and shell; the falling film evaporator is located at the top of the boiler body, and the bottom end of a tube side, on which materials are located, of the falling film evaporator communicates with the inside of the boiler body; an inlet of the variable frequency pump communicates with the bottom of the boiler body, and an outlet of the variable frequency pump communicates with the top end of the tube side, on which materials are located, of the falling film evaporator; and a steam outlet of the steam jetting pump is connected withan inlet of the falling film evaporator and communicates with a shell side on which a heating medium is located. By replacing a traditional internal heating boiling manner with a falling film evaporation manner, the liquidity of wheat juice in a pipe is better, the heating is more uniform, and a coking phenomenon is relatively effectively avoided, so that the falling film type wheat juice boilingsystem has the advantages that the energy source is saved, water for saccharification and cleaning is saved, and the like.

Description

technical field [0001] The invention belongs to the technical field of wort boiling systems, in particular to a falling film wort boiling system and a boiling process thereof. Background technique [0002] In the beer brewing process, there are two main steps: wort preparation and fermentation. After the malt is crushed, it is mixed with hot water to form a mash, which is converted into sugary wort under the action of enzymes. The wort is filtered and added to the boiler, where it is heated and boiled. During the boiling phase, the wort is heated to a boil by internal or external heaters. After boiling, the thermal coagulation is separated in a cyclone (cyclone sedimentation). After that, the wort is cooled and passed into the fermenter, where yeast is put in and fermentation begins. [0003] Wort boiling is a key step in the preparation of wort in the brewing process, and it is also the most energy-consuming link in the entire beer production process (about 40-60% of th...

Problems solved by technology

However, the length of the internal heater tube in the craft brewing industry is generally less than 1.5m. Avoiding coking requires a large pump flow rate. While saving a small amount of heating steam and part of cleaning water, it consumes more electricity and more energy. Today, China's continuous development has fallen behind
