摘 要：山梨酸又称花楸素，是从天然山梨果中提取的新型食品防腐剂。由于其安全性高，毒性低，防腐性能能好，能保持食品原有的风味易被人体吸收，有一定的营养价值等优良性能。普遍应用与食品加工工业，用在保存果品、乳制品、脂肪制品、肉制品等。本文在对比近几年主流的生产方法后选择最新的有机电化学法合成山梨酸法，设计了一个年产1000吨山梨酸的生产车间，对物料、热量、釜体、车间布置等进行了研究。设计内容包含了釜体各部分尺寸、搅拌传动装置、附件(法兰、人孔等)及车间布置等方面的设计，并给出了生产工艺的反应流程简图、车间布置图和反应釜体装配图。

The process design of Sorbic acide for annual output 1000 tons
Abstract: Sorbic acid, also known as Su-Sorbus is from natural mountain extracted pome new food preservatives. Because of its high safety, low toxicity, anti-corrosion performance can be better able to maintain the original flavor of food easily absorbed into the human body, there are some excellent properties, such as nutritional value. General applications and food processing industry, used in preserving fruits, dairy products, fat products, meat products and so on. In this paper, in contrast to the mainstream in recent years after the selection of the latest production methods of organic electrochemical synthesis of sorbic acid method, Designed with an annual production capacity of 1,000 tons of sorbic acid production workshop, the materials, heat, autoclave body, workshop layout, etc. was studied. Design includes body parts of the reactor size, stirring gear, accessories (flanges, manhole, etc.) and plant layout design, etc., and gives the response of the production process flow diagram, plant layout and the reactor body assembly drawing.
