Description
Technical field
The present invention relates to the grease manufacture field, relate in particular to a kind of soft solid grease.
Background technology
Shortening, margarine and other similar solid grease production of products technology, the general business-like mode of production is that the closed continous way is scraped slotting formula heat exchange production technology at present, is specially: emulsification-chilling-kneading-can.Also having a kind of product in addition in the margarine is sheet margarine (sheet grease thickness generally is 5-15mm) or rectangular-shaped margarine, and its manufacture craft is: emulsification-chilling-knead-chilling-stop-pack.In the grease production industry, call the A unit to quenching unit usually; The unit of kneading is called the B unit; Stopping, the unit is called the C unit or the pipe that stops (resting tube).Above-mentioned closed continous way is scraped the brand of inserting formula heat exchange process equipment to be had a lot, for example: Kombinator (German Schrocder company); Votator (U.S. Cherry-Burrell Votator company), Perfector (Denmark Gersternberg&Agger company), Chemctator (Britain Crown Chemtech company).It is that closed is scraped slotting formula heat exchange process continuously that the A unit of these brands all belongs to.Denmark GA company also has the open discontinuous formula A unit-Diacooler of a cover in addition.
The function of A unit is to carry out quick crystallisation by cooling to the grease or the grease emulsion of heating melting; The function of B unit is to follow the A unit, mixes the lubricant component of beginning crystallization curing to make it further homogeneously crystallized; The function of C unit also is further to increase grease emulsion or oil component slowly propelling in the pipe that stops of static state, to increase the crystal growth time of grease in system of processing.
Scrape by present general closed continous way and to insert formula heat exchange production technology gained solid grease product, leave production line after, will in the process that room temperature is placed, continue crystallization, will see that grease hardens gradually on macroscopical.Such solid grease product soft durometer of (20-30 ℃) at ambient temperature can satisfy most of user's preparing various kinds food dessert.But run into winter temperature, especially temperature is in the time of 0-10 ℃, and these greases are met low temperature will produce a large amount of post crystallizations, and the thick arrangement of these crystal grains is disorderly and unsystematic, causes oil and fat product structure on macroscopic view crisp hard, loses the user and makes the soft durometer that food needs.Be highly brittle when hard when grease becomes, the user need be provided with greenhouse, puts in grease in 1 day before use-3 days to rise again, and so both increased user's operating cost, and cost is higher.
Diacooler for GA company; Its crystallization processes route is: the grease emulsion of thawing drenches on the drum crystallizer surface with film like, thickness 1mm, then down with the cutter shovel; The crystallization fragment of collecting under the shovel send the growing the grain room to continue to support crystallization, and the most laggard make-up machine shaping is fuel-displaced.Such technology is because of open crystallization, not enough health; Add that labour and inefficiency cause this technology to lose commercial value gradually; This technology since crystallization time to such an extent as to enough grow crystallization enough abundant, when room temperature during the processing varieties of food items, it is good that the operating characteristics of oil and fat product is obviously scraped slotting formula heat exchange production technology than above-mentioned closed continous way; But run into winter temperature; Especially temperature is at 0-10 ℃; Scrape the slotting the same consequence of formula heat exchange production technology gained solid grease product with suffering with the closed continous way: meet low temperature and will produce a large amount of post crystallizations; And the thick arrangement of these crystal grains is disorderly and unsystematic, causes oil and fat product structure on macroscopic view crisp hard, loses the user and makes the soft durometer that food needs.
Along with the development of food processing, the food user is tending towards using low melting point grease (fusing point is consistent with common butter (butter), 30-36 ℃) for obtaining good mouthfeel in addition.Such low melting point grease must be stored under the 0-10 ℃ of refrigerator cold-storage condition all the year round, otherwise grease loses good operating characteristics with thawing.But after such grease is put refrigerator for a long time, the reason above similar will cause that post crystallization is serious, the thick arrangement of crystal grain is disorderly and unsystematic, cause finally that grease is crisp seriously to lose good operating characteristics firmly.
Therefore, this area presses for provides a kind of at the 0-10 ℃ of solid grease with improved flexibility, so that behind the long-term storage refrigerator, still has good operating characteristics.
