Embodiment 1

[0028] A production process of polycrystalline rock sugar, the operation steps are:

[0029] (1) Dissolving sugar: dissolve white granulated sugar in water at 85°C, stir until the white granulated sugar is completely dissolved, and obtain 62°Bx soluble syrup;

[0030] (2) Ceramic membrane microfiltration: Send the soluble syrup to the ceramic membrane microfiltration working tank, and use a ceramic membrane with a pore size of 200nm for microfiltration clarification, where the transmembrane pressure difference is 0.15MPa, and the filtration temperature is 75°C. Flow velocity is 5m / s, obtains clear syrup standby;

[0031] (3) Ion exchange resin desalination and decolorization: the clear syrup is cooled to 40°C through a plate heat exchanger, and then sent to the first ion exchange resin tower to obtain the first permeate. The flow rate in the resin is 2.0BV / h, and the diameter-to-height ratio is 1 / 3, and then the first permeate is sent to the second ion exchange resin tower to...

[0038] A production process of polycrystalline rock sugar, the operation steps are:

[0039] (1) Dissolving sugar: dissolving the white granulated sugar in water at 80°C, stirring until the white granulated sugar is completely dissolved, to obtain a 60°Bx soluble syrup;

[0040] (2) Ceramic membrane microfiltration: send the slurred syrup to the ceramic membrane microfiltration work tank, and use a ceramic membrane with a pore size of 500nm for microfiltration clarification, where the transmembrane pressure difference is 0.25MPa, the filtration temperature is 80°C, Flow velocity is 6m / s, obtain clear syrup for subsequent use;

[0041] (3) Ion exchange resin desalination and decolorization: the clear syrup is cooled to 43°C through a plate heat exchanger, and then sent to the first ion exchange resin tower to obtain the first permeate. The flow rate in the resin is 2.5BV / h, and the diameter-to-height ratio is 1 / 4, and then the first permeate is sent to the second ion exchange re...

Abstract

The invention discloses a production process of poly-crystal rocky candy. The production process comprises the following six steps: by taking first-grade white sugar as a raw material, dissolving the sugar, micro-filtering and clarifying, desalting and decolorizing by using ion exchange resin, concentrating in vacuum, charging seeds for crystallization, drying and packaging to produce the poly-crystal rocky candy. The poly-crystal rocky candy produced by the method disclosed by the invention is sweet and delicious in taste and white and transparent in color and luster; no sodium hydrosulfite is added for color protection during the overall production, so the product is environmental friendly and safe; the crystallization rate of the rocky candy is above 95%; the problem of low crystallization rate during production of the poly-crystal rocky candy for a long time is solved.

Description

technical field [0001] The invention relates to a production process of polycrystalline rock sugar, belonging to the technical field of rock sugar production. [0002] technical background [0003] Rock sugar is a crystallized re-product of white granulated sugar and is a kind of refined sugar. Because its crystallization is like ice, hence the name rock sugar, also called "ice grain". Rock sugar is pure in quality and not easy to deteriorate. In addition to being edible as candy, it can also be used as a sweetener for high-end foods. Chinese medicine believes that rock sugar has the functions of nourishing the lungs, relieving cough, clearing phlegm and reducing fire. It is also an auxiliary material for making medicinal wine and stewing tonic, and has always been loved by people. In addition to the habit of eating rock sugar in my country, rock sugar is also very popular in countries such as Japan and Southeast Asia. With the development of society and the continuous pro...
