Method for preparing compressible cane sugar from cane sugar syrup

Abstract

The invention belongs to the technical field of cane sugar processing, and particularly relates to a method for preparing compressible cane sugar from cane sugar syrup. The method uses the following raw materials in percentage by weight: 85-98% of refined cane sugar syrup and 1-5% of an anti-crystallization agent, with the balance being water. The method comprises the following steps: mixing the refined sucrose syrup with the anti-crystallization agent and water in proportion, further adding a compressible sugar seed crystal, carrying out mixing, then performing crystallizing and drying in a rake type vacuum drier, and carrying out crushing and screening to obtain a finished compressible cane sugar product. With the method provided by the invention, the process of cane sugar dissolving orpre-crushing is omitted; the adopted rake type vacuum drier is high in drying efficiency, saves time and reduces energy consumption and equipment investment; the integral process is greatly simplified; the raw materials, the anti-crystallization agent and the water are fully stirred in the dissolving process and then are mixed and crystallized, so the prepared compressible cane sugar product is small in particle density, low in particle strength, uniform in particle size and better in flowability and compression formability.

Description

technical field [0001] The invention belongs to the technical field of sucrose processing, and in particular relates to a method for preparing compressible sucrose by using sucrose syrup. Background technique [0002] Sucrose is an abundant renewable resource. Industrial production of sucrose is mostly produced by crystallization method, which is easy to crystallize out of supersaturated aqueous solution. It is anhydrous crystal, colorless and transparent, and can produce large crystals under appropriate conditions. Sucrose crystals belong to the monoclinic crystal system, with large particles and difficult to compress. Even if the sucrose is directly crushed, it is not easy to compress into tablets because of its poor fluidity and high tendency of crystallization adsorption. In order to make sucrose easy to compress directly and meet the development needs of sweeteners in pharmaceutical tablets, food tablets and health care tablets, research on sucrose crystal modificatio...

Problems solved by technology

This method needs to cool down to 5-9°C for crystallization, which requires high energy consumption. In addition, the filter cake needs 10 times the amount of water for washing. The washing water contains sugar, which is easily infected with bacteria and cannot be recycled, resulting in great waste.

[0010] At present, there are generally problems in the production of compressible sucrose, such as large equipment investment, high energy consumption, long operation time, and insoluble auxiliary materials in the product.
