Filter screen mechanism and fruit and vegetable squeezing and grinding machine using same

Abstract

The invention belongs to the field of a fruit and vegetable machine and particularly discloses a filter screen mechanism for a fruit and vegetable squeezing and grinding machine. The filter screen mechanism comprises an upper filter screen and a lower filter screen; a middle ring screen is also arranged between the upper filter screen and the lower filter screen; the middle ring screen is fixedly provided with a shielding ring; the shielding ring is provided with a plurality of notches; the notches are positioned in a mesh region of the middle ring screen; and the aperture of each mesh of the middle ring screen is respectively greater than those of each mesh of the upper filter screen and each mesh of the lower filter screen. The invention also discloses the fruit and vegetable squeezing and grinding machine utilizing the filter screen mechanism, which comprises the filter screen mechanism and a screw drive mechanism. The screw drive mechanism comprises a screw and a center shaft; the center shaft is connected with the screw; the screw is connected with a motor shaft; the screw is a spinning-cone-shaped sphere with a small upper part and a big lower part; the outer surface of the sphere is provided with a helix-shaped convex strip; the center shaft of the screw is coincided with a center shaft of the upper filter screen; gaps are formed between the edge of the screw and the inner walls of the upper filter screen, the middle ring screen and the lower filter screen; and fruits rotate along with the screw in the gaps to be processed. The filter screen mechanism and the fruit and vegetable squeezing and grinding machine have the advantage of multiple functions.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable processing equipment, and in particular relates to a filter screen structure for a fruit and vegetable pressing mill and a fruit and vegetable processing machine using the filter screen structure. Background technique [0002] The existing fruit and vegetable processing machine is used in the family to make a variety of food and beverages. Its science and convenience are recognized by people, and its greatest contribution is to play a positive role in people's dietary health. [0003] The working principles of the existing models can be divided into the following types: (1), horizontal or vertical screw extrusion, such as juice machines, fruit and vegetable machines, etc. (2) Crushing type with cross turret, such as soybean milk machine, blender and cooking machine, etc. (3) Grinding type of ratchet cutterhead, such as juicer, orange juicer, etc. Because there are structural process design pro...
