Method for directly preparing dispersive-type apple grunt high-fiber powder through apple pomace

The invention discloses a method for directly preparing dispersive-type apple grunt high-fiber powder through apple pomace. The method comprises the steps that firstly, the apple pomace which is processed through enzyme deactivation is separated to remove peel and seeds through a cold broken beater and processed through filter pressing through a frame filter press until the water content is reduced to 80%-85% and the soluble solid accounts for 2%-10%; secondly, a hollow blade dryer is adopted, the blade temperature and the blade rotating speed in the drying process are regulated according to the water content of the materials, the materials are dried while dispersed depending on the shearing dispersing and heating functions of blades on the materials and the dehumidification function of a draught fan until the materials are formed into a dispersive scaly shape, and then the dispersive-type apple grunt high-fiber powder is prepared. According to the method, the problems that when standing drying is performed, a high-viscosity dried pulp product is caked, the interior is not prone to being dried and the drying time is long, and when fuel gas drum drying is performed, the product is polluted are solved, the product is in the dispersive scaly shape or power shape after being dried, does not need to be smashed and can be widely applied to baking and various fiber health care products.
