Description

TECHNICAL FIELD

[0001] The utility model relates to gluten detection technical field, concretely relates to a centrifugal screen device for gluten instrument. BACKGROUND

[0002] Before the appearance of the gluten instrument, the traditional gluten content determination method is mainly hand washing method, this method is time-consuming, laborious, and the accuracy is not high. The appearance of the gluten instrument greatly improves the determination efficiency and accuracy, and makes the determination of gluten content more scientific and convenient.

[0003] The working principle of the gluten instrument is based on the characteristics of wheat gluten, that is, the gliadin protein and the glutelin protein are not soluble in water, but can swell by absorbing water, forming a gel-like hydrate with elastic-plasticity. When measuring, a certain amount of flour or whole wheat flour is added to a certain amount of salt water in a washing cup with a screen, mixed to form a dough, then washed with salt water to remove starch and other water-soluble substances in the dough, and obtain gluten. Under the action of centrifugal force, the gluten centrifugates the water on the surface, and part of the wet gluten passes through the screen box hole plate, and the wet gluten content and gluten index in the flour can be obtained after weighing and calculating. After drying the wet gluten, the dry gluten content and gluten water holding rate can be obtained. The gluten is placed in the centrifugal screen for centrifugal operation. Since the gluten is subjected to the action of centrifugal force during centrifugation, the force and friction of the screen are large, so the screen is easily damaged and needs to be replaced. Sometimes the gluten adheres to the screen, and the screening is located at the connection between the first containing groove and the second containing groove, which is not convenient to clean.
