Abstract
A colour monocrystal sugar with sandwich is made up through such technological steps as dissolving granular white sugar in water at 70-80 deg.C, filter, concentrating and loading in crystallizer; dissolving granular white sugar in water, filter, concentrating, colouring and crystallizing to obtain crystal seeds; putting the crystal seeds into swinging crystallizer and cultivating crystal seeds under 0.07-0.085 MPa for 100-150 min, supplementing sugar solution for crystal growth for 24-29 hr, washing in water and dewatering.
Description
The invention belongs to sugar industry, particularly relate to a kind of production technology of colour sandwiched single-crystal sugar.
Sucrose is the water white transparency crystallization, belongs to monoclinic system, and the aqueous solution of sucrose has strong crystallization tendency, and crystalline solid is point (molecule, atom or ion) well-regulated arrangement in the space of its formation, crystal looks like neat, well-regulated geometric shape; Sucrose crystal has 8-12 crystal face.Sucrose dissolves readily in water, and faint hygroscopicity is arranged.Sucrose solubility in water is very big, and increase along with the rising of temperature, chemically, solubility is defined as, under certain temperature and pressure, the maximum gram of the sucrose number that can dissolve in per 100 gram water is called the solubility of sucrose under this temperature, finds out that from its definition solubility is the saturated solution of liquid glucose under this temperature.
People it may be noted that at a certain temperature in daily life, in a certain amount of water, if can dissolve sucrose dissolved rapidly, add some sucrose again, resemble this type of solution that can also continue to dissolve and are called unsaturated solution.For a long time could dissolve if add the sucrose footpath, add Xiao Xu again and just can not dissolve again, this kind can just be the saturated solution under this temperature at a certain temperature with the solution that excessive sucrose reaches poised state.Dissolving is a unity of opposites with crystallization, and dissolving and crystallization are reversible.
When external condition changes, one side reversible reaction is promptly to carrying out.
Show as the dissolving (unsaturated) of crystal when dissolution velocity＞crystallization rate
When dissolution velocity=crystallization rate shows as poised state (saturated)
When dissolution velocity＜crystallization rate shows as crystallization (supersaturation)
With slowly cooling or slowly evaporation of saturated solution, when the sucrose amount of dissolving in the liquid glucose is spent above the sucrose dissolved under this temperature, separate out as no crystallization of sucrose, this liquid glucose is supersaturated solution, supersaturated sugar solution is under stable poised state, can keep constant for a long time, but it is also unstable, as imposes environmental stimuli, add a small amount of brilliant sucrose crystal, vibration, stirring or cold wind stimulate all can make crystallization of sucrose separate out, and is deposited on the crystal, and crystal is grown up.
Existing manufacturing technique can only be produced monochrome, no sandwich monocrystal rock sugar, so kind and tone are single, does not satisfy consumer's requirement.
The preparation technology who the purpose of this invention is to provide a kind of bright and colourful colour sandwiched single-crystal sugar.
Another object of the present invention provides a kind of product that adopts above-mentioned preparation technology to make.
Colour sandwiched single-crystal sugar production technology of the present invention is included under the 70-80 ℃ of temperature, with white granulated sugar and water through dissolving, peace and quiet, filter after, be that to be concentrated into weight concentration under the 0.07-0.085Mpa state be 67-83% at pressure, it is stand-by to drop into crystallizing tank; Again with white granulated sugar and water through dissolving, peace and quiet, filter after, be to concentrate under the 0.07-0.085Mpa state, pour in the bucket after the toning and be incubated at pressure, static crystallization is a crystal seed, colored crystal seed is taken out the back after 50-60 ℃ of following bake drying 24-48 hour, seed selection; At pressure is under the 0.07-0.085Mpa state, carries out growing the grain in the crystallizing tank that the colored crystal seed input of selecting is being rocked, and the time is 100-150 minute; Covering weight concentration then is the long crystalline substance of syrup of 40-50%, and the time is 24-48 hour, washes and dewater to get final product.
Described white granulated sugar course of dissolution should have different regulations by the concentration different needs.Concentration is low excessively, can prolong crystallization time, wastes energy; Excessive concentration, granulated sugar is difficult for off-bottom, and a large amount of sand returns when causing crystallization produce pseudo-brilliant.
Described peace and quiet process can be handled with static peace and quiet method or mechanical oscillation method.
Described filter process is to filter through dissolving with peace and quiet liquid glucose, to select for use 100-120 order copper or stainless steel bolting silk to be filtered usually.
In the syrup of the colored crystallization of described preparation, when white granulated sugar is 50000 parts, add water 10000-25000 part, edible natural pigment is 2-7 part.The color of described colored crystal seed can be made by market demand: red, orange, yellow, green, blue or green, blue, purple isochrome, its quality; to finished product colour sandwiched single-crystal sugar relation greatly, the crystal seed that chooses should be that color is pure; even particle size; must not be mingled with little crystal grain or Icing Sugar, the plane of disruption is many, is irregular; requirement is healed irregular good more; surface area is big like this, and particularly the crystal seed drying that heals is good more, and must not contain sand grains.
Described selection course is that crystal seed is divided into especially big, large size, medium size, trumpet etc. on request:
Extra large size is: the 9-13mm large size is: 7-9mm
Medium size is: the 5-7mm trumpet is: 3-5mm
Described growing the grain process is the process of irregular seed surface being added flat, polishing, typing.
The described long brilliant process of growing up in supersaturated sugar solution for the crystal seed of typing of crossing, the time needs to be controlled between 24-48 hour by size.
Described washing and dehydration are that available 40-60 ℃ hot water cleans because of the colour sandwiched single-crystal sugar surface in the crystallizing tank also speckles with the part liquid glucose, put thereafter and carry out processed in the centrifuge.
Described white granulated sugar through dissolving, peace and quiet after, under vacuum state, concentrate and reach hypersaturated state, making sucrose molecule in the liquid glucose enter space lattice on the seed surface that drops into aligns, promptly be deposited on the crystal grain, thereby crystal is grown up, under dynamic condition, crystallization becomes single, oarse-grained colour sandwiched rock sugar crystal, and this rock sugar is a colour sandwiched single-crystal body rock sugar.
The preparation technology of colour sandwiched single-crystal sugar of the present invention is scientific and reasonable, it is single to have overcome the prior art kind, can not produce the defective of numerous in variety, bright and colourful colour sandwiched single-crystal sugar, has filled up the blank of domestic and international this series products, products made thereby is sparkling and crystal-clear clear, high purity.
Further describe the present invention below in conjunction with embodiment
