Screening device for gingkoes

Abstract

The invention discloses a screening device for gingkoes. The device includes a rack body (1) and at least one layer of transmission device arranged on the rack body (1). Each transmission device comprises a spiral shaft (2) and an optical shaft (3) arranged in parallel to each other. The spiral shafts (2) are rotatably connected to the rack body (1), and the optical shafts (3) are fixedly connected with the rack body (1). The optical shafts are provided with first grooves (31) in the radial directions of the optical shafts, and the first grooves (31) are opposite to the spiral shafts (2). Through the screening device for gingkoes, gingkoes can be screened and classified into different sizes and various specifications, and the shell removal rate of the shell removal process is thus improved.

Description

technical field [0001] The invention relates to the field of ginkgo processing devices, in particular to a ginkgo screening device. Background technique [0002] Ginkgo seed stone, also known as ginkgo, is composed of outer testa, middle testa, inner testa and seed kernel. The fleshy outer testa is generally removed before storage, and the middle testa is mainly composed of cellulose and hemicellulose. For the core shell, the shelling of ginkgo must be carried out before further processing. The traditional method of manually breaking shells to obtain nucleoli is inefficient and has a high rate of breaking kernels. The quality of ginkgo nuts processed by existing shelling equipment is poor, the shelling rate of ginkgo is low, the damage loss of nuts is relatively large, and the separation of shells and kernels is not complete. Therefore, the shelling of ginkgo is the technical bottleneck in the deep processing of ginkgo. After long-term practice, it is found that the main r...

The traditional method of manually smashing shells to obtain nucleoli is inefficient and the rate of breaking kernels is high

The quality of the ginkgo nuts processed by the existing shelling equipment is poor, the shelling rate of the ginkgo is low, the damage loss of the nuts is large, and the separation of the shell and the kernel is not complete, etc.

Therefore, the shelling of ginkgo is the technical bottleneck in the deep processing of ginkgo. After long-term practice, it has been found that the main reason for the difficulty in shelling ginkgo is that the size of ginkgo is not uniform. Larger seeds may be crushed by the shelling machine, resulting in seed The shell and the seed kernel are stuck together and are not easy to separate; the smaller seeds pass through the shelling device without shelling, and the purpose of shelling cannot be achieved, and it is difficult to screen out after mixing with the seed kernel
