Embodiment 1

[0020] The production process of golden granulated sugar produced by air flotation sulfur-free method: machine-pressed cane juice (or mixed juice exuded from beets) is used as raw material, and its manufacturing process is shown in Figure 2. The mixed juice obtained from pressing (or oozing) is filtered through a vibrating curved sieve with a pitch of 2 to 3 mm (the pitch of a non-vibrating curved sieve can reach 3 to 4 mm), and then add H 3 PO 4 The total amount is about 400ppm (the sum of the phosphoric acid in the sugarcane itself and the added phosphoric acid), and at the same time, the pH of the ash is adjusted to 8.0-8.5, and the tube heater is heated at 95-105°C, and most of it is obtained by settling in the sedimentation tank. Clear juice, a small part of the mud juice is filtered with a vacuum suction filter or filter press without filter cloth, and the obtained filtered juice is evaporated and concentrated to 60-65°Bx together with the settled clear juice, which is c...

Embodiment 2

[0032] The production process of brown sugar produced by air flotation sulfur-free method: use machine-pressed sugarcane (or sugar beet oozing mixed juice) as raw material, and its manufacturing process is shown in Figure 3. Each technological index of the cleaning workshop section of this case is the same as embodiment 1. In the lower stage of boiling sugar: when the clear syrup is further concentrated and crystallized, its temperature and concentration are controlled according to the process requirements, and then stirred. When producing brown sugar, the mixture of young sand and mother liquor is formed during the stirring and cooling process to obtain brown sugar; sugar production When powdering, stir, cool down, and grind to get powdered sugar, which can be packaged and shipped after drying.

[0033] Drying process: heat and dry with hot air, or cool and dry naturally.

[0034] Product physical and chemical indicators:

[0035] Appearance: brown sugar is yellow, shiny, w...

Abstract

The invention relates to a flotation without sulfur for producing sugar or brown sugar with the mixed juice for sugar as raw material, which includes the following processes: Mixing juice -> sieve filter -> lime -> heating -> settlement separation -> evaporation -> floating or separation -> cook sugar-honey -> dry -> finished product. The entire process does not need sulfur-fumigation. In the above flotation separating process, it adds the floating agent in the syrup according to the formula to make water insoluble materials, pigments and other impurities adsorbed by flocculation, and then the flocculation floats up under the buoyancy to form dross, and then it removes the dross to further purify the syrup.

Description

technical field [0001] The invention relates to the technical field of sugar production. Background technique [0002] At present, my country's sugar consumption is dominated by white granulated sugar and soft white sugar, accounting for more than 95% of the total consumption. Most of the sugar factories that produce white granulated sugar and soft white sugar use the sulfurous acid process (the process flow is shown in Figure 1), and a small part of them use the carbonic acid process. Both of these production processes must use sulfur fumigation (adding SO 2 ) process to meet the requirements of the sugar cooking process. At the same time, sulfur fumigation plays a role in bleaching and decolorization. The products produced in this way contain a certain amount of SO 2 , which is detrimental to human health. [0003] The use of these two processes has a history of hundreds of years, but people have not been able to find a way to replace sulfur fumigation. With the progr...
