Embodiment 1

[0050] (1) For ingredients, put glucose or F55 fructose with a concentration of 75% from the syrup storage tank into the ingredient tank, and then add ammonia water with a mass concentration of 25% through the metering tank. Note that the ammonia water pipe should be inserted into the bottom of the ingredient tank, and the addition ratio is according to Add concentrated ammonia water to 1% of the dry base of the syrup, and keep stirring. The process of adding ammonia water should be slow and uniform. Adjust the pH of the batching tank to 10-10.5, and the temperature will rise by 5-8°C (if there is a lot of foam, add a small amount of defoamer if necessary).

[0051] (2) Heat exchange. After the batching is completed, the materials are pumped into the plate heat exchanger to exchange heat with the high-temperature materials that have been reacted once to heat up the materials.

[0052] (3) Once sprayed, the material after heat exchange is instantly mixed with steam through the i...

[0057] (1) For ingredients, put glucose or F55 fructose with a concentration of 77% into the ingredient tank from the syrup storage tank, and then add ammonia water with a mass concentration of 25% through the metering tank. Note that the ammonia water pipe should be inserted into the bottom of the ingredient tank, and the addition ratio is according to Add concentrated ammonia water to 4% of the dry base of the syrup, and keep stirring. The process of adding ammonia water should be slow and uniform. Adjust the pH of the batching tank to 10-10.5, and the temperature will rise by 5-8°C (if there is a lot of foam, add a small amount of defoamer if necessary).

[0058] (2) Heat exchange. After the batching is completed, the materials are pumped into the plate heat exchanger to exchange heat with the high-temperature materials that have been reacted once to heat up the materials.

[0064] (1) For ingredients, put glucose or F55 fructose with a concentration of 76% into the ingredient tank from the syrup storage tank, and then add ammonia water with a mass concentration of 25% through the metering tank. Note that the ammonia water pipe should be inserted into the bottom of the ingredient tank, and the addition ratio is according to Add concentrated ammonia water to 3% of the dry base of the syrup, and keep stirring. The process of adding ammonia water should be slow and uniform. Adjust the pH of the batching tank to 10-10.5, and the temperature will rise by 5-8°C (if there is a lot of foam, add a small amount of defoamer if necessary).

[0065] (2) Heat exchange. After the batching is completed, the materials are pumped into the plate heat exchanger to exchange heat with the high-temperature materials that have been reacted once to heat up the materials.

Abstract

The invention discloses a production process of caramel pigment with adjustable chromaticity. The process comprises the following steps: First, glucose or F55 fructose and a catalyst are uniformly mixed in a batching tank, then enter a heat exchanger for heat exchange, and then pass through an injector Instantly mixed with steam to increase the temperature, then enter the reactor for reaction, after the reaction is completed, it will be cooled by the heat exchanger and enter the flash evaporator. The finished product storage tank, after filtering, packs the finished product. If the color value is low, the material enters the heat exchanger through the regulating tank, and the catalyst is added again, and then the above process is repeated. The process of the invention has low equipment requirements and is suitable for large-scale industrial production; the process can adjust the chromaticity according to different production tasks, produce caramel pigments with different chromaticities, expand product coverage, and meet the needs of different customers. The caramel pigment produced by this process has high stability and high red index.

Description

technical field [0001] The invention relates to the technical field of pigment manufacturing, in particular to a production process of caramel pigment with adjustable chromaticity Background technique [0002] Caramel coloring is one of the food colorings with the longest history of human use, and it is also the largest and most popular food additive used by people. It is a thick dark brown viscous substance, which is not a single compound (about 100 different compounds), and its physical properties are dark brown to black liquid, block, powder or paste substance, odorless or Slightly odorous (caramel aroma), with a pleasant bitter taste. [0003] There are two production processes for liquid caramel coloring: normal pressure method and pressurized method. In the past, solid caramel coloring was mainly obtained by spray-drying or freeze-drying liquid caramel coloring. The investment in freeze-drying equipment is too large, and the caramel pigment is easy to adhere to the ...
