Description
Technical field
The utility model relates to grease crystallization separating-extracting apparatus field, relates in particular to a kind of non-isothermal grease crystallization separating-extracting apparatus.
Background technology
The hard fat modification has received big quantity research recently and has paid close attention to; Because unique plasticity oil and fat product can be some oil and fat products such as cake, chocolate, candy, ice river in Henan Province icepro, margarine, shortening; Cocoa butters etc. provide stability and good mouthfeel, improve the quality of products and shelf life.At the hard fat that will expect high-quality, a variety of preparation methods are arranged, but the dry method branch of grease carry technology be one newer; And the technology that has great prospects for development of tool; Because there is not the use of chemical modification and organic solvent in should the technology production process, be a physical process based on fusion-crystallization, environmental sound; Cost is low, and is profitable.
Consider from healthy; Want to change fat constituent, fusion-crystallization possibly be a righttest selectable method, obtains better natural sweet three ester admixtures because can put forward process through the physics branch; Compare with ester exchange with hydrogenation; The biggest advantage of this method is that natural oil therefrom possibly have different metabolic effect to human body with the chemical modification fat by hydrogenation and ester exchange gained, and can not produce trans-fatty acid.
The fusion-crystallization condition has very big influence to crystallization process and characteristics of product, and in general, crystallization process comprises two dynamics steps: at first, become to endorse the birth that is called as crystal; In order to impel the formation of nucleus, supercooling or hypersaturated state begin growth and become crystal as the thermodynamics motive force after nucleus forms; In fact, nucleus formation and crystal growth are always simultaneous, for the branch of accomplishing the grease crystallization is put forward process; The crystallization equipment technology must be complete, controls certain temperature difference, and making has time enough to carry out nucleus formation in the grease molecular crystalline process; And crystal growth, but be applied to the equipment that the grease branch is carried at present, generally be an independent cooler crystallizer; Normally be heated to certain degree to grease, carry out supercooling then, in crystallizer, carry out crystallization, growing the grain; The temperature of grease keeps certain temperature crystallization in the process of crystallization like this, can't from lattice, turn back to behind the molecular crystalline in the oil of liquid, simultaneously because the two-way migration crystallization of crystallization process right and wrong; Sweet three ester molecules of some LMP also are brought in the crystalline solid, and the product purity of crystallization is reduced, and are poor for the applicability of different oils and fats system.
In order to overcome the defective of present prior art equipment, we develop a kind of non-isothermal grease crystallization separating-extracting apparatus, and this equipment has the following advantages; Equipment uses simple to operate, can effectively control the heating-up temperature and the crystallization temperature of material in the grease crystallization process, makes the two-way migration crystallization under non-isothermal condition of grease molecule; Can make sweet three ester molecule multiple degrees of freedoms collision crystallization, crystallization control speed makes the arrangement of the molecular assembly of crystallization; The grease purity of crystallization is than higher; Can realize grease continuous crystallisation under constant difference, use the surface crystallization device can obtain high-melting-point and the solid fraction leach-s/tive that is similar to the solid fat characteristic of butter, purity is high.
