Abstract

The invention discloses a starch viscosity testing system and a starch viscosity measuring method. The starch viscosity testing system is characterized by comprising a constant-temperature heating andstirring device, a viscosity measuring device, a data transmission line and a data recording and displaying device. And the constant-temperature heating and stirring device is one of an air bath, a sand bath, a water bath and an oil bath. The heating mode can be that the viscosity is measured after heating is completed, and can also be that the viscosity is measured while heating. And the constant-temperature heating and stirring device is one of magnetic stirring and mechanical stirring. The starch can be added into a measuring cup at a time and is heated all the time to test the viscosity,or the starch can be replaced again to be dissolved, heated and tested after the viscosity is measured at constant temperature by heating each time. The system has the beneficial effects that the system is convenient to measure, accurate and comprehensive in measured data, wide in application range, low in price, durable, capable of being heated for a long time, convenient to replace and wash themeasuring cup, beneficial to rapid and accurate measurement of the starch viscosity, capable of ensuring accurate parameters in the impregnating compound preparation and control process, high in superior product rate and capable of reducing the cost in a disguised manner.

Description

technical field [0001] The invention relates to the fields of starch, food and infiltration materials, in particular to a starch viscosity test system and a test method. Background technique [0002] Starch is the main component of food. The main ingredient in many foods is starch. Gelatinization of starch refers to the process of swelling and breaking starch crystallites in a suspension composed of starch and water. The gelatinization process and conditions of starch have a significant impact on the properties of starch solutions and related products. By testing the viscosity curve of starch, it can provide a basis for the determination of starch gelatinization temperature, and can also provide guidance for temperature selection in the production process. Promote the correct use of starch raw materials and ensure the quality of their products. Therefore, it is very important for starch manufacturers or individuals to choose a viscosity testing system with reliable qualit...
