Design Of Dairy Plant With Annual Output 90,000 Tons

A plant of Jinan Wei Wei Dairy Company with annual output of 90,000 tons was designed.The design includes product project making, technique design, shop-floor diagram, material andcalories balance in the process of dairy, device selection, water-electricity-steam balance, laborbalance, organizational control chart, environmental protection programming and dirty waterprocessing, investment cost, profits, wax and wane balance point evaluation.In the product selection, Jinan Wei Wei Dairy Company considered the neutral milk andvarious type lactobacillus beverages as their major product. According to the characteristics andshelf of the pure milk and the lactobacillus beverage, UHT and the high temperature with shorttime sterilization was applied respectively.This factory address was chosen in the Jinan south Yaoqiang industry area with beautifulenvironment and convenience transportation. The whole design of the plant was rational,especially in the shop design, the main part was in the workshop central while other assistanceestablishments around the main workshop, then the whole factory design was packed tightly, atthe same time it infinitely reduced the distance of the piping and material transportation,economized obviously energy sources.On the basis of the characteristics of the raw milk and different product, the materialcalculation was carried out with the difference of dissimilar packing was considered. The plankand tube type heat exchanger was choosed respectively as the heat exchanger equipments. Thecalories calculation was carried out in the different phase of cooling off, preparing heat,homogenizing and UHT sterilizing the raw milk, and its heat recycle percentage amounts to56.41%.The production equipments were selected in the different phase as the economy andtechnique and the production craft was took into account roundly. In order to control the wholeproduct process and make sure the dairy safety and quantity stabilities, the assistance facilities ofrefrigeratory base, material base, assay room and research and development room was designed.According to the production demand of the plant, the usage amount of the water, electricity,vapor was estimated, their biggest dosage was 49 t/h, 400 kW, 2383kg/h respective. The diameterof the different pipeline was calculated, the running water, ice water, steam and cleaning pipelinewas DN100, DN76, DN125, DN80, respective.A new management mode of "company+base+peasant household" was adopted to carry outthe factory organization and managements. The labor plan was very reasonable, and the threeclasses system was applied to continue the production.Jinan Wei Wei Dairy Company can keep on the developing strategy to protect theenvironment, the anaerobic assimilation method was used to deal with the dirty water.In this design, the total investment was 79,280,000 RMB, the year profits amount to27,103,500 RMB, the wax and wane balance point was 11620 tons which was only 11.67% ofthe design ,the conducting safety percentage was up to 55.11%, and the investment recycleperiod was expected about 3 years.
