Problems solved by technology

The structure of the existing drying tower and its operating principle lead to the unsatisfactory drying effect, mainly as follows: 1. The drying uniformity is poor; 2. The free falling drying method of grain particles will produce a considerable amount of broken particles. It greatly affects the quality of grain processing and brings certain difficulties to normal storage; 3. The drying efficiency of the drying tower is relatively limited. Due to the retrograde between the drying air flow and the grain particles, the relative speed is high, and it is necessary to achieve large-scale drying. The operation index requires a high-temperature drying environment of 140-230°C, the particles are severely burnt, and the burnt rate is generally between 6-15%, especially in large-scale grain mechanized planting and grain production areas, such as corn planting areas. The maturity of corn is uneven, and the drying operation of the existing drying tower equipment will make the burnt situation more serious; 4. The processing cost of the existing drying method is high, and the processing cost is about 90 yuan / ton, and the grain reserve processing funds high pressure

Abstract

The invention discloses a double-layer tubular rice drying device with uniform material distribution. An inner barrel and an outer barrel define a double-layer structure, and a cover plate is arrangedat the top opening position of the outer barrel, and provided with an installation opening and a plurality of air outlets; a distributor is arranged at the installation opening, and used for feedingbetween the inner and outer barrels, and the inner barrel is internally provided with a blast cavity; and an upper barrel body of the inner barrel is provided with a conical guide surface of which theouter diameter is increased gradually from top to bottom, and the side wall of a lower barrel body of the inner barrel is provided with a plurality of blast holes. Through the optimized double-layertubular rice drying device with uniform material distribution, the structure design is optimal and rational, and material distribution is performed in the outer barrel through a distributor; dry air is fed through the blast cavity in the inner barrel, and moves upward after being used for drying grains, and the dry air with moisture and dust is discharged from the air outlets on the top; the drying effect between the inner and outer barrels is improved, so that hot air is thoroughly circulated in a drying barrel, and the temperature of the drying barrel is ensured at the middle part through adistribution barrel; and the utilization rate of heat is improved.

Description

Technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice drying and dust removal equipment. Background technique [0002] Effective control of the moisture content of stored grain is the basic requirement for long-term safe storage of grain. At present, the most widely used mechanized operation grain drying equipment is mainly the drying tower, which is the mainstream product of my country's grain drying equipment. The drying tower uses the upward blowing hot drying airflow and the continuous falling human grain particles to reverse each other to dry the grain particles. The structure of the existing drying tower and its operation principle lead to the drying operation effect is not very satisfactory, mainly: 1. The drying uniformity is poor; 2. The free fall drying method of grain particles will produce a considerable amount of broken particles. It greatly affects the quality of grain processing and brings certain difficul...
