Problems solved by technology

Resulting in low product purity and poor taste
This process also has many disadvantages: First, the process uses lime precipitation to remove impurities. After natural precipitation or plate and frame pressure filtration, a large amount of residue will be produced, which will seriously pollute the environment; secondly, the method uses Lime needs to be calcined. On the one hand, it consumes a lot of energy and is accompanied by waste discharge. At the same time, it also adds a process section and increases production costs. Third, the product undergoe...

Embodiment 1

[0029] Such as figure 1 Shown, a kind of novel process of directly edible syrup of the present invention comprises the following steps:

[0030] Juicing: Squeeze sugarcane through a juicer to obtain sugarcane juice;

[0031] Pre-filtering, after the gained sugarcane juice is pre-filtered through a sieve, larger bagasse is removed, and the aperture of the sieve is 100 mesh;

[0032] Microfiltration membrane filtration: the sugarcane juice collected by pre-filtration is microfiltered through a 500nm ceramic membrane, the feed liquid temperature is 20°C, and the filtration pressure is 0.5Mpa to obtain sugarcane juice clear liquid with a sucrose concentration of 12%;

[0033] Membrane concentration: the sugarcane juice clear liquid enters the nanofiltration membrane filter for concentration. The material of the nanofiltration membrane is polyethersulfone, the molecular weight cut-off is 100Da, the nanofiltration pressure is 4.0Mpa, and the volume of the sugarcane juice clear liqu...

Embodiment 2

[0040] The difference between this embodiment and embodiment 1 is: lack the step of microfiltration, concrete process is as follows:

[0041] Juicing: Squeeze sugarcane through a juicer to obtain sugarcane juice;

[0042] Pre-filtering, after the gained sugarcane juice is pre-filtered through a sieve, larger bagasse is removed, and the aperture of the sieve is 100 mesh;

[0043] Membrane concentration: the sugarcane juice clear liquid enters the nanofiltration membrane filter for concentration. The material of the nanofiltration membrane is polyethersulfone, the molecular weight cut-off is 100Da, the nanofiltration pressure is 4.0Mpa, and the volume of the sugarcane juice clear liquid is concentrated to 30%;

[0044] Ion exchange desalination: the concentrated sugarcane juice is desalted and decolorized with an anion and cation exchange resin bed, the diameter to height ratio is 1 / 7, the flow rate is 4BV / h, and the temperature is 30°C; the anion and cation exchange resin mixed...

Embodiment 3

[0051] The difference between this embodiment and embodiment 1 is that the concentration process adopts a two-effect evaporator, and the specific process is as follows:

[0052] Juicing: Squeeze sugarcane through a juicer to obtain sugarcane juice;

[0053] Pre-filtering, after the gained sugarcane juice is pre-filtered through a sieve, larger bagasse is removed, and the aperture of the sieve is 100 mesh;

[0054] Microfiltration membrane filtration: the sugarcane juice collected by pre-filtration is microfiltered through a 500nm ceramic membrane, the feed liquid temperature is 20°C, and the filtration pressure is 0.5Mpa to obtain sugarcane juice clear liquid with a sucrose concentration of 12%;

[0055] Membrane concentration: the sugarcane juice supernatant enters the second-effect evaporator for concentration, and the volume of the sugarcane juice supernatant is concentrated to 30%;

[0056] Ion exchange desalination: the concentrated sugarcane juice is desalted and decolo...

Abstract

The invention provides a production process and a production device of golden sugar. The production process comprises the following steps: pressing sugarcane or beets to obtain cane sugar juice; pre-filtering the cane sugar juice through a coarse filter and feeding the pre-filtered crane sugar juice into a microfiltration membrane for filtering to obtain clear cane sugar juice; pre-concentrating the clear cane sugar juice to obtain a pre-concentrated solution; feeding the pre-concentrated solution into ion exchange resin for desalting to obtain a permeation solution; feeding the permeation solution into an evaporator for concentrating to obtain cane sugar concentrated liquid; heating the cane sugar concentrated liquid to be oversaturated, adding crystal seeds, naturally cooling and crystallizing, and centrifuging the obtained crystals to obtain golden sugar crystals; drying the golden sugar crystals to obtain a finished product of the golden sugar. The production device comprises the coarse filter, a microfiltration membrane filter, a nanofiltration membrane filter, an anion exchange resin bed, a cation exchange resin bed and the evaporator which are connected in sequence. The production method provided by the invention is capable of continuously producing high-quality golden sugar, the chromatic value of the obtained product is 800-3,000, the desalting rate is high, and the yield is high.

Description

technical field [0001] The invention belongs to the technical field of sugar production, and in particular relates to a production process and device of golden sugar. Background technique [0002] Golden sugar, also known as yellow granulated sugar and golden granulated sugar, is sugar without honey that contains certain nutrients. The color is pale yellow. Its production process is similar to that of white sugar, but the nutrients inside are not completely filtered during the production process, so it retains part of the sugarcane flavor and nutrition, and retains a lot of natural minerals. [0003] With the continuous improvement of the production level of our people, people's consumption of sugar is also increasingly diversified. In recent years, the edible demand for brown sugar in northern my country and other places is also increasing year by year. Therefore, in Guangxi, my country's main sugar-producing area, some small and medium-sized sugar factories produce yell...
