糖化的批次高低关键看过滤槽；华艺公司对过滤槽从宏观到每一个细节都做了研发改进设计；特别是“结合糖”的快速溶出做了大量的理论研究和实验，建立了一系列的数学模型，突破了一些列技术难题。使过滤速度提上新的台阶。可以把全部过滤操作时间控制在 2 小时以内。
Key technology of fi lter tank:
The quality of saccharifying depends on the filter tank. Huayi Company has made R&D and improved design from macroscopic aspect to all details. A great number of theoretical researches experiments have been carried out according to the fast dissolving of sugar, and a series of mathematical models have been established, which fi nally solved the technical problem to enhance the fi ltering speed to a new height. The whole filtering operation can be controlled within 2 hours.
① Dynamic control mathematical model of fi ltration: The wort turbidity, fl ow rate and grain layer resistance ,proper fi ltering fl ow control, raker revolving speed and lifting height, are fed back through the master automatic control inspection means to ensure the wort to maintain smooth from the beginning to the end or execute necessary grain layer treatment timely by controlling the appropriate leaching fl ow, raker revolving speed and rise and fall height.
② Improvement of fi ltering raker and inner washing grain technology:
The special raker structure designed to a nicety is very helpful for the improvement of percolation property of the grain layer. The grain washing speed, intensity and time will influence the filtering efficiency of wort, leaching of harmful substances and oxidation. Especially, the application of washing tank technology makes the rapid digestion of the combined saccharides increase the fi ltering speed. A great number of theoretical researches and experiments have been carried out, and a series of mathematical models have been established, which is verifi ed by project cases.
③ Improvement of the cleaning system at the bottom of the sieve plate:
Incomplete cleaning of the mud-like stuff at the bottom will affect the fi ltering quality and speed of wort in the next pot. The special structure of the cleaning nozzle makes the spraying angles mutually overlapped. The total phased array layout guarantees the leaning has no dead corner left and there is no need to disassemble the sieve plate for cleaning manually, which would reduce the labor intensity and the deformation of the sieve plate.
