辽宁石油化工大学毕业设计（论文）用纸PAGE IPAGE I15000吨/年浓缩梨汁厂的初步设计摘 要本设计主要是进行年产15000吨浓缩梨汁工厂设计。在对全球和我国梨产品产销和加工的现状进行充分调研的基础上，分析了我国浓缩果汁的生产和贸易现状。拟定在辽宁省葫芦岛市建昌县投资浓缩梨汁生产厂。首先依据拟定的产量对生产车间进行了物料衡算、热量衡算；进而依据国际市场要求进行了车间的工艺设计，进行了主要的设备选型。第三，对公用事业、土建等方面也作了一个初步的设计方案。整个设计从节能的角度出发选择设备。生产流程尽量提高机械化、自动化水平，同时力求技术上先进，质量上可靠，布局上合理、规范。关键词：浓缩，梨汁，蒸发，冷却，工厂设计The preliminary design of concentrated pear juice factory of 15000 tons/yearlyAbstractThis design is primarily for the annual treatment of 15000 tons concentrated pear juice. On the basis of full investigation for the global and Chinas pear production and processing status, the design analyses our countrys concentrated pear juice production and trade status. It plans to invest to build a concentrated pear production plant in Liaoning province, city of Huludao. First of all, calculate the number of production materials and aequum for the production workshop based on the elementary output; moreover, make a technologic design for the workshop and do the major equipment sampling according to the demand of the international market. Thirdly, make a preliminary design for the public sectors and earthwork.This design chooses equipments from the perspective of energy-efficient. Production processes to maximize mechanization, automation level, while seeking to technically advanced, reliable quality, reasonable and normal layout.Key words:concentrate; pear juice; evaporate; cooling; factory design目录TOC \o 1-2 \h \u HYPERLINK \l _Toc12432 1 文献综述 PAGEREF _Toc12432 1 HYPERLINK \l _Toc15104 1.1 梨的概述 PAGEREF _Toc15104 1 HYPERLINK \l _Toc2923 1.2 梨汁的发展及生产状况 PAGEREF _Toc2923 4 HYPERLINK \l _Toc26470 1.3 梨汁的生产工艺 PAGEREF _Toc26470 5 HYPERLINK \l _Toc22130 1.4 梨汁生产时所遇的问题 PAGEREF _Toc22130 6 HYPERLINK \l _Toc65 2 工艺流程及工艺论证 PAGEREF _Toc65 8 HYPERLINK \l _Toc24108 2.1 工艺流程 PAGEREF _Toc24108 8 HYPERLINK \l _Toc12752 2.2 工艺论证 PAGEREF _Toc12752 8 HYPERLINK \l _Toc12390 3 物料衡算与设备选型 PAGEREF _Toc12390 12 HYPERLINK \l _Toc17167 3.1 浓缩果汁班产量的确定 PAGEREF _Toc17167 12 HYPERLINK
