Description
Technical field
The utility model relates to a kind of vapo(u)rization system that Wort boiling adopted in beer production.
Background technology
Existing Wort boiling system comprises boiling pot, whirlpool tank and water cooler, and wheat juice is heated in boiling pot, makes the dimethyl sulphide presoma in it be cracked into free dimethyl sulphide, and this cacogeusia material and other unfavorable flavour substances are evaporated gradually; Then, the wheat juice in the boiling pot flows in the whirlpool tank by pipeline, through leaving standstill and isolate hot trub; At last, effusive hot wheat juice then obtains required cold wheat juice after the water cooler cooling from whirlpool tank.But in such boiling process process; usually can find: because the wheat juice total evaporation in the boiling pot is lower; perhaps be contained in ducted pumping rate when excessive when string; make that the evaporation surface of wheat juice is too small relatively; the dimethyl sulphide presoma does not have the time enough cracking in the wheat juice; free dimethyl sulphide after the cracking does not separate fully yet, has exceeded the desired value of 100 μ g/T down to free dimethyl sulphide in wheat juice and presoma total amount thereof, thereby has caused the defective of beer flavor difference.And in order to overcome above-mentioned drawback, usually adopt the method that wheat juice is boiled strongly to overcome again, to guarantee that dimethyl sulphide has sufficient time to cracking, result that can be such usually makes again and the decline of solidifiable nitrogen content and the rising of wheat juice thermal load in the wheat juice also causes the big drawback of energy consumption simultaneously.Therefore, how to improve the vaporization efficiency of wheat juice, and can protect the effective ingredient in the wheat juice again, become to press for now the technical problem of solution.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, and a kind of content that can reduce the dimethyl sulphide in the wheat juice is provided, and can improve the solidifiable nitrogen content again, and the low flash evaporation system for wheat juice of energy consumption.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this flash evaporation system for wheat juice comprises boiling pot, whirlpool tank and water cooler, the discharge gate of wherein said boiling pot is connected with the opening for feed of above-mentioned whirlpool tank by pipeline, it is characterized in that: also comprise, the bottom is provided with the flashing chamber of opening for feed and discharge port, the opening for feed of this flashing chamber is connected in the discharge port of above-mentioned whirlpool tank by feed-pipe, the discharge port of described flashing chamber links to each other with the liquid material import of described water cooler by discharge nozzle, simultaneously on this flashing chamber, also be provided with the venting port that is connected with vacuum pump by vapor pipe, and make air pressure in the above-mentioned flashing chamber be lower than the saturated vapor pressure of described wheat juice.
As further improvement of the utility model, can be equipped with the vacuum-evaporation condenser on the described vapor pipe, the middle water of this vacuum-evaporation condenser into and out of the hole respectively the water pipe by separately be connected with the heat energy storage tank, and the middle water in this heat energy storage tank by pipe connecting be used for the interchanger of preheating wheat juice and link to each other.Like this, can further reclaim the heat energy in the secondary steam, realize the purpose of environmental protection and energy saving
Can also be equipped with wheat juice pump on the described feed-pipe, between the feed-pipe of this wheat juice pump inlet place and described discharge nozzle, also be connected with the intervalve of band control valve.So that the wheat juice circulating and evaporating in the flashing chamber is controlled the back steam output in the flashing chamber flexibly.
Compared with prior art, advantage of the present utility model is that (1) improved the quality of wheat juice: because the wheat juice that comes out from whirlpool tank in the utility model is imported into the flashing chamber, utilize bleeding of vacuum pump, make in the precipitation process of circling round and the vacuum-evaporation process in the unfavorable taste and the odoring substance that regenerate taken out of with the form of secondary steam, promptly produced back steam output, thereby made that unfavorable flavour substances obviously reduces in the wheat juice; Simultaneously by the vacuum-evaporation in the above-mentioned flashing chamber, shorten in the boiling pot boil between, reduce total evaporation and kept solidifiable nitrogen in the wheat juice as much as possible; Also reduce wheat juice thermal load in addition widely, finally improved the stability of wort quality and beer flavor.(2) energy consumption is low: utilize the evaporation again in the flashing chamber, and the original heat energy consumption that can reduce the heating of wheat juice greatly and boil, thus reached save energy, environmentally friendly purpose.(3) since flashing chamber in prior art between whirlpool tank and the water cooler, when therefore transforming, do not influence the carrying out of ordinary production, be not subjected to the restriction of existing Wort boiling system yet, can be linked in the existing sacchariferous equipment easily, can also be simultaneously use, and because the shortening of Wort boiling time, can improve the throughput of saccharification line widely for two or many saccharification lines.So the utility model cost of investment is low, throughput is strong, and energy consumption is low, can make wort quality optimized again, therefore is worth transforming on existing saccharification line using.
