The main tasks of production process design include two aspects: one is to determine the sequence of each production process from raw materials to finished products, that is, to explain the changes and flows of substances and energy in the production process, and which biological reaction or chemical processes and equipment are used, and the other is to draw a process flow chart.
17. The design of production technology generally goes through three stages: schematic stage, sketch stage and flow chart stage.
18. The equipment involved in the fermentation workshop is divided into professional equipment, general equipment and non-standard equipment. Professional equipment refers to professional equipment used only in fermentation plants, such as fermentation tanks and saccharifying pots; General equipment refers to pumps, fans and other equipment that can be used in various industries; Non-standard equipment refers to storage, pools and other facilities used in production workshops except professional equipment and general equipment.
19. Commonly used solid mechanical conveying equipment includes: belt conveyor, bucket conveyor, screw conveyor, etc.
20. Workshop layout design must be based on full investigation and necessary information, as the basis or reference for design. These materials include: production process flow chart; Material balance data and material characteristics; Equipment information; Consumption of public systems, water supply and drainage, supply points, heating, refrigeration, compressed air, external pipeline data, etc. Civil engineering data and labor safety, release and explosion-proof data; Workshop organization and personnel information; The overall layout of the factory; Some standard information about layout.
2 1. Fermentation plant generally consists of production workshop, auxiliary workshop, power workshop, warehouse and yard, three wastes treatment part, administrative welfare part before the plant, etc.
22. The internal composition of the production workshop of a fermentation plant generally includes three parts: production, assistance and life. The production part includes: raw material section, production section, finished product section and recovery section; Auxiliary parts include: ventilation and air conditioning room, power distribution room, workshop laboratory and control room; The living part includes: workshop office, meeting room, dressing room, lounge, bathroom and toilet.
23. For large breweries, the main production workshops are malt workshop, saccharification workshop, fermentation workshop and packaging workshop.
24. Cooling engineering is an important part of brewery, monosodium glutamate factory and fruit winery in fermentation industry. There are many kinds of refrigeration methods, and the mechanical refrigeration method is the most widely used.
25. The characteristics of pipeline layout in fermentation workshop are: selecting suitable pipelines and valves (pollution-proof, seamless steel pipes); Select the correct pipe connection method (including threaded connection, welding and flange connection); Reasonable arrangement of pipelines (minimize pipelines and reduce the chance of bacterial pollution); Eliminate the dead angle of pipeline.
26. Water supply and drainage design is divided into two parts: water supply project and drainage project, in which water supply project includes water intake, water treatment and water transmission and distribution. Drainage works include: drainage pipe network, sewage treatment and utilization.
27. The main task of heating engineering design is the design of boiler room or heating station. Its main contents are: to determine the steam supply for production, heating and living in the whole plant; Determine the steam source of steam supply; Selecting boilers according to steam consumption; Design the boiler room according to the model and quantity of the selected boiler; Boiler water supply and water treatment design; Configure the whole plant steam pipe network, etc.
28. The composition of product cost includes: raw material cost (refers to the processing materials that constitute the product); Expenses for auxiliary materials (directly or indirectly used for production, but not constituting expenses for various materials of products); Fuel cost (the cost of heat source material to provide heating steam for the process); Power consumption fee (energy cost directly consumed by production); Wages of production workers; Production workers' wage surcharge (labor fund, medical expenses, cultural and educational subsidies, welfare subsidies); Workshop expenses (all expenses required for the management and organization of production in the workshop); Enterprise management fee (all expenses incurred by the enterprise management department for managing and organizing production); Promotion expenses (including packaging expenses, transportation expenses, consignment distribution and other commercial expenses).
29. The process design drawing is the main drawing of production process design, which usually includes three aspects: process flow diagram, equipment layout diagram and pipeline layout diagram.
30. Design principle of process route: ensure that the product quality meets the national standards, and the exported products must also meet the quality requirements of the sales area; Try to adopt mature and advanced technology and equipment; Minimize the discharge of "three wastes" and have perfect treatment measures for "three wastes"; Ensure safe production and the safety of personnel and equipment; Mechanization and automation should be adopted in the production process as far as possible to achieve stable and high yield.
The purpose of 3 1. heat balance is to provide basis for process design and operation optimization in quantitative production.
32. Significance of heat balance calculation: Through heat balance calculation, the quota consumption index of energy consumption in the production process is calculated; Accounting data is the basis for selecting equipment types and determining their scale and quantity; It is the basis of organizational management, production, economic accounting and optimization. \
