Production process and device of golden sugar

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...

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 undergoes long-term high-temperature evaporation to produce a Maillard reaction. The pigments in its products are not natural pigments, which are not beneficial to the human body; fourth, the concentration process of this method uses a multi-effect evaporator, which consumes a lot of energy, and the production cost remains high; fifth, the process is relatively complicated. There are a lot of equipment, the control process is complicated, and the area is large, and the infrastructure cost is also high

Sixth, the process does not have a desalination process section,
