Modified starch reactor

Abstract

The invention provides a modified starch reactor and relates to the technical field of modified starch production equipment. The modified starch reactor comprises a support, a power device, a stirring shaft, a reaction tank and a stirring spiral tape; the two ends of the reaction tank are erected on the support; the stirring spiral tape is arranged inside the reaction tank; a feeding hole, an observation hole and an air outlet are formed on the upper side of the reaction tank, while a discharge hole is formed in the lower side of the reaction tank; the stirring spiral tape is mounted on the stirring shaft; the stirring shaft extends out of the middle parts of the two ends of the reaction tank and is mounted on the support; one end of the stirring shaft is connected to the power device by use of a crosshead coupling; a temperature control layer is arranged on the outer side of the reaction tank; the temperature control layer is a hollow cavity and filled with water or oil; the lower end of the temperature control layer is connected to a heating device. The modified starch reactor has the advantages that temperature in the reaction tank is monitored in real time by use of a temperature sensor arranged inside the reaction tank and control on the temperatures in the reaction tank is completed automatically, and therefore, the production efficiency is greatly improved and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of modified starch production equipment, in particular to a modified starch reactor. Background technique [0002] In the past ten years, the output of modified starch in the world has grown rapidly. At present, the annual output of modified starch in the world is close to more than 8 million tons. [0003] The development of modified starch in my country started relatively late, starting in the 1980s. It has been applied in many fields such as textile, papermaking, packaging, food, feed, casting, medicine, construction, petroleum, etc. The application of modified starch in my country is still an emerging business, and there is a big difference with foreign countries in terms of the type, quality and application range of modified starch. Only in terms of the types of modified starches, more than 2,000 kinds of modified starch products have been developed and listed abroad, including oxidized starch, acid-m...

Problems solved by technology

[0005] However, the current production equipment for modified starch is still very old and cannot meet the current production needs. A Chinese patent on a building material processing equipment (notification number CN 202778357 U) specifically relates to a new type of building material processing mixer

It consists of a cube-shaped body, with a stirring shaft connected to the stirring motor inside the body, and a double-helical ribbon-type stirring paddle on the stirring shaft; multiple feeding ports are provided on the top of the body, and at least one feeding port is connected to the The perforated plate in the body is connected; the side end of the bottom of the body is equipped with a discharge port, but it can only be used for materials with large particle sizes, and the mixing is not uniform, and the temperature control cannot be performed.
