Manufacture method for production of dextrin by microwave method

Abstract

The invention discloses a manufacture method for production of dextrin by a microwave method. the manufacture method comprises the following steps: Step 1, selecting corn starch as a material; Step 2, spraying the material into a nitric acid solution and uniformly stirring; Step 3, digging equal quantity of the material in a material barrel into a spreading device by the utilization of an automatic feeding system, and spreading the material onto a conveyor belt by the spreading device; Step 4, setting operation speed of the conveyor belt according to corresponding material thickness, sending the material into a multistage microwave drying oven, heating, drying, dextrinizing and sterilizing; and successively raising heating temperature of each stage in the multistage microwave drying oven; Step 5, sending the material into an agitator and detaching; Step 6, screening by a vibrating screen; Step 7, detecting dextrin; and Step 8, carrying out measurement packing according to standards. Due to line production of the whole production line, degree of automation is high. Meanwhile, temperature and moisture of the material can be monitored at real time, thus guaranteeing stability of product quality.

Description

technical field [0001] The invention relates to a method for producing dextrin by a microwave method, and belongs to the technical field of dextrin production. Background technique [0002] At present, the existing dry method of producing dextrin, due to the limitation of the volume of the reaction pot, this will cause a certain difference in the degree of dextrinization between the pots, so that the unit batch is too small (such as using a large volume Blender, on the one hand, the volume of the blender is limited, and on the other hand, the production cost is increased) to form a product whose quality is not stable enough. This method will also bring about uneven heating in the pot and uncontrollable dust, and at the same time greatly reduce the risk of dust explosion. Contents of the invention [0003] Objective: In order to overcome the deficiencies in the prior art, the present invention provides a method for producing dextrin by microwave method.
