VAC-0.8 真空冷却装置设计摘要真空预冷是一种理想的预冷技术,它是目前降温速度最快的一门制冷技术。它具有冷却速度快, 冷却效果均匀, 清洁无污染等众多优势, 因此被广泛应用于食品保鲜中的预冷环节。 它可在蔬菜、 水果和花卉收后第一时间内消除其田间热等生理活动和生化变化, 使产品在短时间内迅速均匀冷却,减少和抑制微生物, 并能保持原有产品的色、香、味和营养成分等。 该技术已在蔬菜、 果品和鲜花等农产品以及肉类,鱼类,烘焙类,熟食等众多食品加工领域得到了广泛的应用。但是,目前对熟肉的真空冷却的专用设备产品却较少。本装置是在真空原理和制冷原理以及产品的加工工艺的基础上进行设计的,通过对不同阶段的计算进行真空泵的选型和压缩机的选型; 以及与压缩机相适配的冷凝器进行设计计算,选取合理的风机;对捕水器进行结构计算,隔热层厚度计算,以及设计计算;对真空箱进行结构计算和形状设计; 通过对装置的各部件设计后, 对装置的整体布局进行设计, 使装置整体结构布局合理,紧凑。对于不同的产品,由于其加工工艺不同,对真空冷却装置的设计有一定的影响。本设计以熟牛肉为设计产品而进行设计,在实际选用产品时应加以注意。关键词真空冷却、预冷、制冷系统、食品工业VAC-0.8 Vacuum cooling device VAC-0.8 真空冷却装置设计2 ABSTRACT Pre-cooling vacuum is an ideal pre-cooling technology, it is now the fastest cooling a refrigeration technology. It is cooling fast, uniform cooling effect, clean non-polluting, and many other advantages, it is widely used in food preservation in the pre-cooling sectors. It can be vegetables, fruits and flowers to the first time to eliminate the hot field activities and physiological and biochemical changes, the products in a short period of time cooling quickly and evenly, reduce and inhibit microbial, and maintains the original color products, smell and taste and nutritional composition. The technology has been in vegetables, fruit and flowers, and other agricultural products as well as meat, fish, baking category, cooked food, and many other areas of food proce...
