Method for producing powder caramel color through combination of spiral conveyer and extruder

Abstract

The invention relates to a method for producing powder caramel color through the combination of a spiral conveyer and an extruder, which can effectively solve the problems that the operation is easy, the product quality is poor and the production efficiency is low. The method is characterized by comprising the following steps of: firstly mounting the spiral conveyer and the extruder to form a conveyance and extrusion integrated production device, conveying a raw material of glucose or cane sugar into the spiral conveyer, mixing the raw material with water and acid liquid, regulating the pH value of the raw material, enabling the raw material to enter an area I of the spiral conveyer, heating a saccharification reaction to form an acidolysis sugar liquid, feeding the acidolysis sugar liquid into an area II of the spiral conveyer, injecting an amino compound to carry out a Maillard reaction to form the liquid high-temperature caramel color, heating the mixture by an area III of the spiral conveyer, feeding the mixture into the extruder, carrying out vacuum air-liquid separation on the mixture, cooling down by a coolant to obtain a solid, and crushing the solid to obtain finished-product caramel color. The method for producing the powder caramel color through the combination of the spiral conveyer and the extruder has the advantages of simpleness and easiness for operation, integration of conveyance and extrusion, good product quality and high production efficiency, and is an innovation on the production of the caramel color.

Description

technical field [0001] The invention relates to chemical industry, in particular to a method for producing powdered caramel pigment by combining a screw conveyor and an extruder. Background technique [0002] Caramel pigment, also known as caramel color, is a dark brown to black liquid, block or powder, slightly bitter and slightly caramel flavored. The country has used it as a food additive in 1974 for wine, beverages, soy sauce , chocolate, syrup and other industries, caramel coloring is one of the most popular food additives used in the food industry. [0003] At present, the production methods of domestic caramel pigments are mostly traditional workshop-style manual methods, and there are few manufacturers with more scientific methods. What is commonly used now is that one is the normal pressure method, that is, the open pot production method. The sugar raw material is heated to a certain temperature under normal pressure, and various additives such as ammonia water and...
