 摘 要：山梨酸又稱花楸素，是從天然山梨果中提取的新型食品防腐劑。由于其安全性高，毒性低，防腐性能能好，能保持食品原有的風(fēng)味易被人體吸收，有一定的營養(yǎng)價值等優(yōu)良性能。普遍應(yīng)用與食品加工工業(yè)，用在保存果品、乳制品、脂肪制品、肉制品等。本文在對比近幾年主流的生產(chǎn)方法后選擇最新的有機(jī)電化學(xué)法合成山梨酸法，設(shè)計了一個年產(chǎn)1000噸山梨酸的生產(chǎn)車間，對物料、熱量、釜體、車間布置等進(jìn)行了研究。設(shè)計內(nèi)容包含了釜體各部分尺寸、攪拌傳動裝置、附件(法蘭、人孔等)及車間布置等方面的設(shè)計，并給出了生產(chǎn)工藝的反應(yīng)流程簡圖、車間布置圖和反應(yīng)釜體裝配圖。

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.

Keywords：Sorbic acid；Mass Balance；Heat Balance；Kettle Design；Plant Layout
