Production process design of the main tasks include two aspects: one is to determine the sequence of the production process from raw materials to finished products, that is, to explain the changes in the production process of materials and energy and the flow direction, the application of which biological reaction or chemical process and equipment, and the second is to draw the process flow diagram.
17. The design of the production process generally undergoes three stages: the production process schematic stage, the production process sketch stage, the production process flow diagram stage.
18. The equipment involved in the fermentation plant is divided into specialized equipment, general equipment and non-standard equipment. Professional equipment refers to fermentation tanks, saccharification pots and other specialized, only for the fermentation plant equipment; general-purpose equipment refers to pumps, fans and other industries can be used in the equipment; non-standard equipment refers to the production plant in addition to professional equipment and general-purpose equipment used in the production of supporting storage, pools and other facilities.
19. Commonly used solid mechanical conveying equipment: belt conveyor, bucket conveyor, screw conveyor and so on.
20. Workshop layout design must be based on full investigation, master the necessary information as the basis for design or for reference. These materials include: production process flow chart; material accounting data and material properties; equipment information; utility system consumption, water supply and drainage, supply point, heating, refrigeration, compressed air, outside the pipe information, etc.; civil engineering information and labor safety, put live, explosion-proof information; workshop organization and staffing information; general layout of the plant; the layout of some of the normative information.
21. Fermentation plant generally consists of production plant, auxiliary workshop, power plant, warehouse and yard part, three waste management part, the administrative welfare part of the plant before the district.
22. The internal composition of the fermentation plant production workshop generally includes production, auxiliary, living three parts. Production part includes: raw materials section, production section, finished product section, recycling section; auxiliary part includes: ventilation and air-conditioning room, transformer and power distribution room, workshop laboratory, control room; life part includes: workshop office, meeting room, locker room, rest room, bathroom and toilet, etc..
23. For large-scale beer factory's main production workshop are: malt workshop, saccharification workshop, fermentation workshop and packaging workshop.
24. Cooling engineering is an important part of breweries, monosodium glutamate (MSG) factories and fruit wine factories in the fermentation industry. There are many methods of refrigeration, and the mechanical refrigeration method is the most widely used.
25. Fermentation workshop piping layout features: choose the right pipe and valve (to prevent contamination, seamless steel pipe); choose the right pipe connection (threaded, welded and flanged three ways); reasonable layout of the pipeline (to minimize the pipeline, reduce the chance of bacterial contamination); to eliminate the dead ends of the pipeline.
