The processing technology of concentrated orange juice whose annual output was 8000 tons was mainly introduced in the design,which focused on the factory process design of concentrated orange juice,took the workshop process design as the main body,and put forward various requirements to assist department as the basis of non-process design.The development prospect,pandect of design,technological process,balance of material and heat,equipment selection,calculation of water consumption and steam electricity for the factory,plane arrangement,sewage disposal and economic accounting were summarized respectively in the design that was divided into nine parts,and five design drawings of factory were drawn.The navel orange of Sichuan which had higher juice yield was used to be the raw material.The concentrated orange juice with 80%～85% of solid content was gained through the pretreatment of orange, squeezing juice,concentrating and sterilizing,there were a lot of terpenoids bitterness substances in orange peel and seeds,which had a great influence on the flavor and taste of concentrated orange juice,so oil removing was the special and essential step in the processing technology of orange juice.The heating temperature and time should be controled in the machining process,including the choice of equipment,in order to make the best economic benefit, reach the maximum efficiency.The ratio of saccharic acid was deployed in the process,so it not only prevented the breeding of microorganism,but also was convenient for transportation and reduced the economic loss,and it was a processing method that had a better prospect in the processing industry of fruit and vegetable juice. |
