Corncob pith cutting and obtaining device for food chemical industry

Abstract

The invention discloses a corncob pith cutting and obtaining device for food chemical industry. According to the corncob pith cutting and obtaining device, corncobs are distributed to be consistent through vibration, then corncob piths with the high pentosan content are separated from other positions and separately extracted through annular cutting, and the grade of processed raw materials is increased. The corncob pith cutting and obtaining device is characterized in that a plurality of supporting columns are arranged on one side of a bottom plate, one end of the bottom plate is lower than the other end of the bottom plate, and a vibrating net is arranged on the bottom plate and is close to the other end of the bottom plate; a vibrating motor is placed on the bottom plate, side wing baffles are arranged at the edges of the two sides of the bottom plate, and a plurality of partition plates are arranged on the bottom plate in parallel; the partition plates and the side wing baffles areparallel, the partition plates extend from one end of the bottom plate to the middle of the bottom plate, and the multiple partition plates and the flange baffles on the two sides divide the bottom plate into sliding grooves with the same width; and an arc-shaped press plate is placed between every two adjacent partition plates and located at one end of the corresponding sliding groove, and a guiding plate is placed between every two adjacent partition plates and located at the other end of the corresponding sliding groove.

Description

technical field [0001] The invention relates to a corn cob pith cutting device for food chemical industry, which relates to a device for separately cutting corn cob pith in the corn cob during the deep processing of the corn cob, and belongs to the field of food processing. In particular, it relates to a method of vibrating to make the arrangement of corncobs consistent, and then separate and extract corncob pith with high pentosan content and other positions through circular cutting, so as to improve the grade of processed raw materials. Background technique [0002] At present, in the corn processing process, after the corn is separated, the corncob is directly used as a fuel for incineration, and some directly grind the corncob for use as feed, but the corncob pith in the corncob contains a large amount of pentosan , and pentosan is the main raw material for the preparation of furfural, carboxymethyl cellulose and xylitol, so the corncob pith can be cut and utilized.

[0002] At present, in the corn processing process, after the corn is separated, the corncob is directly used as a fuel for incineration, and some directly grind the corncob for use as feed, but the corncob pith in the corncob contains a large amount of pentosan , and pentosan is the main raw material for the preparation of furfural, carboxymethyl cellulose and xylitol, so the corncob pith can be cut and utilized. All the corncobs are crushed, and then the subsequent acid hydrolysis and other processes are carried out, and all the corncobs are used as raw materials. Compared with the fact that there is no distinction between the corncob pith and other parts of the raw material grade, the overall raw material grade is reduced, and the corncob is processed. The shell of the corncob has been treated uselessly, which wastes a lot of resources. Therefore, when using it as a raw material, it is necessary to separate the high-grade corncob pith separately. Because the corncob pith has a soft structure and the corncob shell is relatively hard, the existing corncob pith used The crushing equipment cannot guarantee the integrity of the corncob pith and the stability of the internal and external components, especially for crushing the whole corncob

[0003] Publication number CN105772194A discloses a corn cob crushing device, comprising an upper box, a lower box, a coarse powder mechanism, a fine powder mechanism and a suction mechanism; the coarse powder mechanism is installed on the top of the lower box; the fine powder mechanism Installed on the inner side of the lower box; the upper box is installed on the upper part of the lower box; the suction mechanism is installed on the bottom of the fine powder mechanism; the coarse powder mechanism is composed of a driving rod and a plurality of alloy knives; the fine powder The mechanism is composed of a thin screw; the suction mechanism is composed of a fan and an air pipe; one end of the air pipe is installed at the bottom of the lower box; the other end is installed in conjunction with the fan; the coarse powder mechanism and the fine powder mechanism are Driven by the power mechanism, the corncob crushing device of the invention crushes the whole corncob without separating and extracting the corncob pith separately, resulting in low-grade raw materials and low proportion of pentosan in the crushing process. The corn cob pith is crushed, so that part of the pentosan changes in the mechanical movement, affecting the internal components
