Method for processing sulfur-free konjaku flour

Abstract

The invention discloses a method for processing sulfur-free konjaku flour. Adopted processing equipment is grinding and drying equipment, raw materials are added from a hopper on an external circulating pipe feeding opening, and the raw materials enter an auxiliary grinding machine through a first-stage internal circulating pipe after being smashed by a centrifugal fan impeller of a main grindingmachine; the materials enter the main grinding machine to be smashed again after being smashed by a centrifugal fan impeller of the auxiliary grinding machine; the materials are smashed to the required particle size in a circulating manner, powder enters a cyclone dust remover through a feeding pipe of the auxiliary grinding machine to achieve airflow drying, moisture is exhausted by a bag filter,the materials return to the main grinding machine through an external circulating pipe to be smashed, and the moisture of the other materials is absorbed; and after the materials are smashed and dried to be qualified, a valve of a dust exhaust opening of the cyclone dust remover is closed, and the materials are collected by the bag filter. In the smashing and drying process, airflow guided in bythe internal circulating pipe impacts a kinetic energy recycling impeller to achieve cyclic utilization of kinetic energy, the materials are not bonded in the smashing process, and low energy consumption is achieved; the operation temperature is controllable, and the operation temperature is low; and the original taste of food can be kept, and the defects of an existing method are overcome.

Description

technical field [0001] The invention relates to a processing method of sulfur-free konjac flour, which belongs to the technical field of dry crushing of materials. Background technique [0002] Konjac is usually made into powder and eaten. Konjac flour is rich in starch and glucomannan, which has the effect of preventing high blood pressure and hyperlipidemia. During the process of processing fresh konjac into konjac flour, it is easy to oxidize and change color, and it is difficult to control the crushing and drying temperature , is not conducive to maintaining the nutrition and taste of konjac. Contents of the invention [0003] The equipment adopted in the processing method of sulfur-free konjac flour of the present invention is a grinding and drying equipment, and the grinding and drying equipment includes a main mill, an auxiliary mill, a first-level internal circulation pipe, a secondary internal circulation pipe, and an external circulation pipe , cyclone dust coll...
