Embodiment Construction

[0010] A kind of production method of edible grade anhydrous glucose of the present invention, comprises the following steps:

[0011] 1. Spread glucose monohydrate evenly on the fixed plate of the oven, heat slowly with hot air, and control the heating rate at 20°C per hour. When the hot air temperature reaches 65°C, turn on the dehumidification fan to dehumidify, and control the heating rate at 30°C When the hot air temperature reaches 90°C, turn off the dehumidification blower, rapidly raise the temperature to 98°C, and keep it for 1 hour.

[0012] 2. The above process lasts for about 4 hours, and then the material is discharged, air-dried to cool down, crushed to the required particle size, packaged, and the food-grade anhydrous glucose product is obtained.

[0013] 3. Wherein, the distribution tray of the oven should be provided with vent holes with a diameter of 6mm, and heat insulation nets and white cloth should be laid.

[0014] The above-described embodiments are on...

Abstract

The invention discloses a production method of edible grade anhydrous dextrose. The production method comprises the following steps of 1, evenly laying dextrose monohydrate into a fixing disc of a drying oven, conducting heating slowly through hot air with the temperature rising speed being controlled to be 20 DEG C / h, when the temperature of the hot air reaches 65 DEG C, switching on a dehumidification fan for dehumidification, controlling the temperature rising speed to be 30 DEG C / h, when the temperature of the hot air reaches 90 DEG C, switching off the dehumidification fan, quickly raising the temperature to 98 DEG C, and maintaining the temperature for one hour, wherein a material distribution disc of the drying oven is required to be provided with gas vents with the diameter being 6mm, and a thermally-insulating mesh and white cloth are laid; and 2, maintaining the process described in the step 1 lasting for approximately four hours, then conducting discharging, airing and cooling, pulverizing the material to reach the required granularity, and conducting packaging, so that an edible grade anhydrous dextrose finished product is obtained. By means of the production method ofthe edible grade anhydrous dextrose, the defects that an old production process is long in procedure, complex to control and high in investment are overcome; and the production method is simple in process, wide in application and low in investment, the granularity is easy to control, and the production method can be applied and popularized on a large- scale conveniently.

Description

technical field [0001] The invention relates to a production method of anhydrous glucose, in particular to a production method of food-grade anhydrous glucose with simple process, wide application, small investment and easy particle size control. Background technique [0002] At present, all manufacturers of anhydrous glucose in China are of pharmaceutical grade and implement the standards of the Pharmacopoeia 2010 edition. Since there are few manufacturers using food-grade anhydrous glucose (GB / T20880-2007), the market demand is not large, so some food factories, veterinary drug factories, and refractory factories use pharmaceutical grade instead of food-grade glucose, which bears higher raw material costs. cost. [0003] In addition, the traditional corn method to produce anhydrous glucose is difficult to treat the three wastes, and it is difficult to control the particle size of the direct crystallization method. Contents of the invention [0004] In order to solve th...
